PHP - Deleting Multiple Rows From Mysql Table In Php Using Checkboxes
Hi,
I am having difficulty deleting rows in my table using check boxes. I have all the check boxes displaying for each row and a delete button below the table. However when i click on the delete button it isnt deleting the checked rows, i have displayed the code below that i am using; Code: [Select] <?php $result = mysql_query("SELECT * FROM contact ORDER BY msg_id ASC"); echo "<table border='1'> <tr> <th>Delete</th> <th>Message ID</th> <th>Name</th> <th>Email</th> <th>Message</th> </tr>"; while($row = mysql_fetch_array($result)) { ?> <td align="center" bgcolor="#FFFFFF"><input name="checkbox[]" type="checkbox" id="checkbox[]" value="<?php echo $row['del_id']; ?>"></td> <?php echo "<td>" . $row['msg_id'] . "</td>"; echo "<td>" . $row['name'] . "</td>"; echo "<td>" . $row['email'] . "</td>"; echo "<td>" . $row['msg'] . "</td>"; echo "</tr>"; } echo "</table>"; ?> <td colspan="5" align="center" bgcolor="#FFFFFF"><input name="delete" type="submit" id="delete" value="Delete"></td> </tr> <?php // Check if delete button active, start this if(isset($_GET['delete'])) { for($i=0;$i<$count;$i++){ $del_id = $checkbox[$i]; $sql = "DELETE FROM contact WHERE id=".$_GET['del_id']; $result = mysql_query($sql); } // if successful redirect to delete_multiple.php if($result){ } } mysql_close(); ?> Please help Thank you Similar TutorialsHi, guys. I am a php newb and stuck (see title). I it will only send the value of 1 tick box over to the page "delete_message.php" This is what i have so far: Code: [Select] <?php // get messages $result = mysql_query("SELECT * FROM tbl_pvt_msg WHERE to_UID='$UID'"); if (!$result) die("Query to show fields from table failed"); while ($data=mysql_fetch_array($result)) { $_SESSION['from_UID']=$data['1']; UIDtoemail(); $from_email=$_SESSION['from_email']; $contents=$data['3']; $timesent=$data['4']; $msg_ID=$data['0']; echo "<form action='scripts/delete_message.php' method='POST' >"; echo "<tr><td>$from_email</td><td>$contents</td><td>$timesent</td><td><input type='checkbox' value='$msg_ID' name='msg_ID' /></td> </tr>"; } // turn uid into email function UIDtoemail(){ $from_UID=$_SESSION['from_UID']; $result = mysql_query("SELECT * FROM tbl_usr WHERE UID='$from_UID'"); if (!$result) die("Query to show fields from table failed"); $data=mysql_fetch_array($result); $_SESSION['from_email']=$data['7']; } ?> </table> <input type="submit" value="Delete" id="delete" /> </form> How would I make a script that would delete any row in a MySQL table that was more than 7 days old? Ok I am trying to delete some rows from a database. I have done this before with success so I thought I could use the same method just modify it a little and it would work. Man was I wrong. Any help on this is much appreciated below is my code. Code for the Query to get the data from the database and for displaying the results in a table: Code: [Select] //GET DATA $sql = "SELECT * FROM `".$tblname."` ORDER BY $orderby $sort LIMIT $startrow,$limit"; $result = mysql_query($sql) or die(mysql_error()); $result2 = mysql_query($sql); //START TABLE AND TABLE HEADER echo "<form name='form1' method='post' action=''><table style='font-size:9.5px;'>\n<tr><th>Delete</th>"; $array = mysql_fetch_assoc($result); foreach ($array as $key=>$value) { if($config['nicefields']){ $field = str_replace("_"," ",$key); $field = ucwords($field); } $field = columnSortArrows($key,$field,$orderby,$sort); echo "<th>" . $field . "</th>\n"; } echo "</tr>\n"; //reset result pointer mysql_data_seek($result,0); //start first row style $tr_class = "class='odd'"; //LOOP TABLE ROWS while($row = mysql_fetch_assoc($result)){ echo "<tr ".$tr_class.">\n<td><a href='remove_rec.php?id=". $rows['ID'] . "'><p>Delete</p></a>"; echo "</td>"; foreach ($row as $field=>$value) { echo "<td>" . $value . "</td>\n"; } echo "</tr>\n"; //switch row style if($tr_class == "class='odd'"){ $tr_class = "class='even'"; }else{ $tr_class = "class='odd'"; } } //END TABLE echo "</table>\n</form>"; Here is the code that should delete the row: Code: [Select] $tblname = 'tablename'; // get value of id that sent from address bar $id=$_GET['ID']; // Delete data in mysql from row that has this id $sql="DELETE FROM $tblname WHERE ID='$id'"; $result=mysql_query($sql); // if successfully deleted if($result){ echo "Deleted Successfully"; echo "<BR>"; echo "<a href='leads3.php'>Back to Results</a>"; } else { echo "ERROR"; } When I click on the link to delete a record it redirects me to the appropriate page with the "Deleted Successfully" message but when I go to view the results the row was not deleted. Any help on this would, again, be greatly appreciated. Hey All, I tried seraching, but I'm not sure what exactly to search for. Here's what I need to do, and any push in the right direction would be great: I have a PHP form, with the Following: Text Box: Student ID Checkboxes for Activities What I need to do is somehow loop through and make a new row for each activity. Example, if I entered Student ID 105 and Activities are Basketball, Baseball, and Chess Team, I need three different rows in the database each listing the individual activity and the student ID. Any suggestions? I know how to do this if it was one entry (radio buttons) but want to be able to enter multiple rows at a time. Thanks! I want to delete rows in a table of my database using check-box. Here are my codes below: Code: [Select] <?php $con = mysql_connect('localhost', 'root', '') or die ('Connection Failed'); mysql_select_db('img', $con) or die ('Connection Failed'); $display = mysql_query("SELECT * FROM photos WHERE email='$lemail'"); echo '<input type="submit" value="Delete" name="del"/>'; echo "<table> <tr> <th>#</th> <th>Images</th> <th>Image description</th> <th>Delete</th> </tr>"; while($row = mysql_fetch_array($display)) { echo "<tr>"; echo "<td>".$row['img_ID']."</td>"; echo "<td><img src='folder/".$row['imaged']."' alt='alt text' width='100' height='100' class='thumb'/> </td>"; echo "<td>".$row['image_description']."</td>"; echo '<td><input type="checkbox" name="delete[]" value="'.$row['img_ID'].'"/></td>'; echo "</tr>"; } echo "</table>"; echo "</form>"; if (isset($_POST['delete'])) { $del = $row['img_ID']; for($i=0;$i<count($_POST["delete"]);$i++) { if($_POST["delete"][$i] != "") { $str = "DELETE FROM photos WHERE img_ID='$del' "; mysql_query($str); echo "Record Deleted."; } } } mysql_close($connect); ?> Here are the problems: 1/ Not working at all, I mean no image is being deleted 2/ At then end, I display a message that the record has been deleted, but if I check multiple checkbox, it keeps writing the message "Records deleted" multiple times My images are stored in a folder while its details in database... Help, thank you Hello all, i have a table that displays data from mysql, now i want to update multiple rows from that table with checkboxes, the value will basically just switch from 'new' to 'done' so far i have this: Code: [Select] <tbody> <tr class="first"> </tr> <?php $ticketde=0; while ($ticketde < $numpscde) { $f1pscde=mysql_result($ticketresultde,$ticketde,"id"); $f2pscde=mysql_result($ticketresultde,$ticketde,"ticket"); $f4pscde=mysql_result($ticketresultde,$ticketde,"date"); $f5pscde=mysql_result($ticketresultde,$ticketde,"ip"); $f6pscde=mysql_result($ticketresultde,$ticketde,"done"); $setdone = ($f6pscde["done"] == 'n') ? "<a href=\"donepsc.php?id=".$f1pscde."\"><img src=\"ico_new.gif\" alt=\"new\" /></a>" : $f6pscde["done"]; if(isset($_POST['setdone'])){$checkbox = $_POST['checkbox']; $id = "('" . implode( "','", $checkbox ) . "');" ; $sql = "UPDATE ticket SET done='done' WHERE id='$f1pscde'"; $result = mysql_query($sql) or die(mysql_error()); } ?> <tr class="first"> <td class="tc"><font face="Arial, Helvetica, sans-serif"><?php echo $f1pscde; ?></font></td> <td class="tc"><font face="Arial, Helvetica, sans-serif"><?php echo $f2pscde; ?></font></td> <td><font face="Arial, Helvetica, sans-serif"><?php echo $f4pscde; ?></font></td> <td class="tc"><font face="Arial, Helvetica, sans-serif"><?php echo $f5pscde; ?></font></td> <td class="tc"><font face="Arial, Helvetica, sans-serif"><?php echo $setdone; ?></font></td> <td class="tc"><input name="checkbox[]" type="checkbox" id="checkbox[]" value="<? echo $f1pscde['id']; ?>"></td> </tr> <?php $ticketde++; } ?> </tbody> </table> <center><input type="submit" name="setdone" id="setdone" value="Set selected to done" class="button"/> - <input type="submit" name="exporttxt" id="exporttxt" value="Export selected to .txt" class="button"/> </center> </fieldset> </form> I found that checkbox code sample on some other site and tried to implement it, i don't really know where to go from here, as it's a total mess to me now, any help would be greatly appreciated. Ok I'm trying to insert multiple rows by using a while loop but having problems. At the same time, need to open a new mysql connection while running the insert query, close it then open the previous mysql connection. I managed to insert multiple queries before using a loop, but for this time, the loop does not work? I think it is because I am opening another connection... yh that would make sense actually? Here is the code: $users = safe_query("SELECT * FROM ".PREFIX."user"); while($dp=mysql_fetch_array($users)) { $username = $dp['username']; $nickname = $dp['nickname']; $pwd1 = $dp['password']; $mail = $dp['email']; $ip_add = $dp['ip']; $wsID = $dp['userID']; $registerdate = $dp['registerdate']; $birthday = $dp['birthday']; $avatar = $dp['avatar']; $icq = $dp['icq']; $hp = $dp['homepage']; echo $username." = 1 username only? :("; // ----- Forum Bridge user insert ----- $result = safe_query("SELECT * FROM `".PREFIX."forum`"); $ds=mysql_fetch_array($result); $forum_prefix = $ds['prefix']; define(PREFIX_FORUM, $forum_prefix); define(FORUMREG_DEBUG, 0); $con = mysql_connect($ds['host'], $ds['user'], $ds['password']) or system_error('ERROR: Can not connect to MySQL-Server'); $condb = mysql_select_db($ds['db'], $con) or system_error('ERROR: Can not connect to database "'.$ds['db'].'"'); include('../_phpbb_func.php'); $phpbbpass = phpbb_hash($pwd1); $phpbbmailhash = phpbb_email_hash($mail); $phpbbsalt = unique_id(); safe_query("INSERT INTO `".PREFIX_FORUM."users` (`username`, `username_clean`, `user_password`, `user_pass_convert`, `user_email`, `user_email_hash`, `group_id`, `user_type`, `user_regdate`, `user_passchg`, `user_lastvisit`, `user_lastmark`, `user_new`, `user_options`, `user_form_salt`, `user_ip`, `wsID`, `user_birthday`, `user_avatar`, `user_icq`, `user_website`) VALUES ('$username', '$username', '$phpbbpass', '0', '$mail', '$phpbbmailhash', '2', '0', '$registerdate', '$registerdate', '$registerdate', '$registerdate', '1', '230271', '$phpbbsalt', '$ip_add', '$wsID', '$birthday', '$avatar', '$icq', '$hp')"); if (FORUMREG_DEBUG == '1') { echo "<p><b>-- DEBUG -- : User added: ".mysql_affected_rows($con)."<br />"; echo "<br />-- DEBUG -- : Query used: ".end($_mysql_querys)."</b></p><br />"; $result = safe_query("SELECT user_id from ".PREFIX_FORUM."users WHERE username = '$username'"); $phpbbid = mysql_fetch_row($result); safe_query("INSERT INTO `".PREFIX_FORUM."user_group` (`group_id`, `user_id`, `group_leader`, `user_pending`) VALUES ('2', '$phpbbid[0]', '0', '0')"); safe_query("INSERT INTO `".PREFIX_FORUM."user_group` (`group_id`, `user_id`, `group_leader`, `user_pending`) VALUES ('7', '$phpbbid[0]', '0', '0')"); mysql_close($con); } include('../_mysql.php'); mysql_connect($host, $user, $pwd) or system_error('ERROR: Can not connect to MySQL-Server'); mysql_select_db($db) or system_error('ERROR: Can not connect to database "'.$db.'"'); } So I need to be able to insert these rows using the while loop.. how can I do this? I really appreciate any help. I have a bad way with words, so if the title doesnt make much sense nor my post, I apolagize! But I am using a while loop and mysql_fetch_array to echo all information in a table in mysql. With each entry, I have included a button that executes a delete query for that entry. Code: [Select] $delquery="DELETE FROM requests WHERE user = '".$row['user']."'"; mysql_query($delquery,$link2); echo "<font size='19px' color='#009933'>User deleted from request database.When I click the button, the message is echod in every entry listed on the page, and nothing happens. I figured Id use delete from the username, so that way mysql will know which one to delete... but Idk when I think about it thats dumb and makes no sense. Im stuck. This side of the application im trying to make is the admin side where I can process requests. After I process the request I delete it from the database so I know I processed it. I have no idea what query to use for this. Anybody know how I could do this?

I'm working on a csv upload script (part of a bigger thing i'm building), so i read in the csv to a multipdimensional array and then build a query that inputs all rows in one query - i read this is the most efficient way to import multiple rows of data at once(rather than multiple insert statements). Just for illustration here's the code i use to build the query so you understand what i'm on about: Code: [Select] $sql = "INSERT INTO teams (company, teamname, teamnum, amountraised, country, president) VALUES "; // $rows is a count of the rows in the csv for($i=1; $i<$rows; $i++){ $sql.="('{$myarray[$i][0]}','{$myarray[$i][1]}','{$myarray[$i][2]}','{$myarray[$i][3]}','{$myarray[$i][4]}','{$myarray[$i][5]}')"; echo $i . "<br/>"; if($i >= 1 && $i < $rows - 1) { $sql.= ","; } } Anyway, the issue is that one of the fields("teamnum") needs to be unique - so i've set this as unique on the table in mysql. But when i run my query it doesn't import anything if one of the records isn't unique. What i really want is for it to import the ones it can and catch the ones it cant import to present to the user. So my question is - to acheive the above would i need to rewrite the query so that it inserts each row one at a time, instead of all together? Or can someone point me in the right direction for a better solution? Probably something very simple i've missed i am sure... Thanks chaps! I'm trying to echo multiple rows from a MySQL database with no luck. I've tried this code and many other combinations with it, but can't seem to get a result. Quote $query = "select email,mens,womens from newsletters"; $result = mysql_query($query); while ($row = mysql_fetch_assoc($result)) {foreach ($row as .$email. .$mens. .$womens.) {echo "$email - $mens - $womens<BR>";}} What am I doing wrong? Hi All, I'm hoping someone can help me. I'm looking to create a form that will submit multiple entries to a MySQL database depending on the options selected on the form. I am able to submit single entries, but the multiple entire is a bit of a mystery to me. I have attached an JPG image to show an example of how I would like the form to work. I have also added the description/explination below to this example: Example 1 The form was completed and three access types were selected. Thus Three entries, all with the Same Reference number were captured into the database Example 2 The form was completed and Two Access Types were selected. Thus Two entries, all with the Same Reference number were captured into the database Example 3 The form was completed and Four Access Types were selected. Thus Four entries, all with the Same Reference number were captured into the database Hi, I'm very new to these forums and php alike. I've been working on this bit of code for weeks now. I've written numerous versions and made endless revisions; trying pieces from many similiar source and well, it's still not quite working out for me. The form I've been trying to finish will have multiple rows. The user will input values specific to each row, but I'm trying to make it so that each row is synonymous with each other in regard to the database table. Like an order form, an inventory form, or a roster. I'd really like to make this code work out because I can think of numerous applications for it's use. I'm sure others could use it for even more. So, as you see; the html code represents the table that contains the form. Currently, I only have five of these rows in the form, but would like for anybody using the code to be able to add in code for as many rows in the table as needed. Code: [Select] <html> <head> <title></title> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"> </head> <body> <FORM action="post_multiple.php" method="POST"> <table width="80%" border="1"> <tr> <td>Vendor</td> <td>Item Description</td> <td>Quantity</td> <td>Price</td> </tr> <tr> <td><select name="vendor" id="vendor" > <option value="other1">other1</option> <option value="other2">other1</option> <option value="other3">other3</option> <option value="other4">other4</option> <option value="other5">other5</option> </select></td> <td><input name="description" type="text" id="description" size="50" /></td> <td><input name="quantity" type="text" id="quantity" size="50" /></td> <td><input name="price" type="text" id="price" size="50" /></td> </tr> <tr> <td><select name="vendor" id="vendor"> <option value="other1">other1</option> <option value="other2">other1</option> <option value="other3">other3</option> <option value="other4">other4</option> <option value="other5">other5</option> </select></td> <td><input name="description" type="text" id="description" size="50" /></td> <td><input name="quantity" type="text" id="quantity" size="50" /></td> <td><input name="price" type="text" id="price" size="50" /></td> </tr> <tr> <td><select name="vendor" id="vendor"> <option value="other1">other1</option> <option value="other2">other1</option> <option value="other3">other3</option> <option value="other4">other4</option> <option value="other5">other5</option> </select></td> <td><input name="description" type="text" id="description" size="50" /></td> <td><input name="quantity" type="text" id="quantity" size="50" /></td> <td><input name="price" type="text" id="price" size="50" /></td> </tr> <tr> <td><select name="vendor" id="vendor"> <option value="other1">other1</option> <option value="other2">other1</option> <option value="other3">other3</option> <option value="other4">other4</option> <option value="other5">other5</option> </select></td> <td><input name="description" type="text" id="description" size="50" /></td> <td><input name="quantity" type="text" id="quantity" size="50" /></td> <td><input name="price" type="text" id="price" size="50" /></td> </tr> <tr> <td><select name="vendor" id="vendor"> <option value="other1">other1</option> <option value="other2">other1</option> <option value="other3">other3</option> <option value="other4">other4</option> <option value="other5">other5</option> </select></td> <td><input name="description" type="text" id="description" size="50" /></td> <td><input name="quantity" type="text" id="quantity" size="50" /></td> <td><input name="price" type="text" id="price" size="50" /></td> </tr> <tr> <td><select name="vendor" id="vendor"> <option value="other1">other1</option> <option value="other2">other1</option> <option value="other3">other3</option> <option value="other4">other4</option> <option value="other5">other5</option> </select></td> <td><input name="description" type="text" id="description" size="50" /></td> <td><input name="quantity" type="text" id="quantity" size="50" /></td> <td><input name="price" type="text" id="price" size="50" /></td> </tr> </table> <input type="submit" name="Submit" value="Submit" /> </FORM> </body> </html> In the php script I've tried using the count, loop, if, several others functions to try to get it to insert all the completed rows from the form into the table but just can't seem to get it to work out. Anyways, here's a representation of what i'd like to achieve. Not necessarily the code I've written trying to accomplish this, I'd have to upload a book if that were the case. <?php ini_set('display_errors','On'); error_reporting(E_ALL); $host="localhost"; // Host name $username="root"; // Mysql username $password="password"; // Mysql password $db_name="testing"; // Database name $tbl_name="test_multiple"; // Table name // Connect to server and select databse. mysql_connect("$host", "$username", "$password")or die("cannot connect"); mysql_select_db("$db_name")or die("cannot select DB"); //declarations $vendor = $_POST['vendor']; $description = $_POST['description']; $quantity = $_POST['quantity']; $price = $_POST['price']; // Check if button name "Submit" is active, do this $sql1="INSERT INTO $tbl_name (vendor, description, quantity, price) VALUES ('".$vendor."', '".$description."', '".$quantity."', '".$price."')"; $result1=mysql_query($sql1); mysql_close(); ?> If anybody can suggest where I need to go with that, that would be great. Like I said above, I've tried about everything I could find any reason to from forum threads I had found in google searches and whatnot. Also, if there is a good article, link or tutorial that would address this that anybody knows about that would be great. However, I'm not looking for a link to a product or plugin that will do this stuff for me. I'm trying to get halfway decent at php and would like to have working code for myself to build upon, modify, and learn from. Any help is greatly appreciated!!!!

ROW ID #44108) product_ section.catpage (MUST BE ONLY THE ROW WITH THE LOWEST SECTION ID, I.E. ROW ID #44108) product_ section.relative_order (MUST BE ONLY THE ROW WITH THE LOWEST SECTION ID, I.E. ROW ID #44108) I currently have.... SELECT customer_favourites.cust_id, customer_favourites.prod_id, product.code, product.product_name, product.hidden, product_section.section_id, product_section.relative_order, product_section.catpage FROM customer _favourites INNER JOIN product ON customer_favourites.prod_id = product.id INNER JOIN product_section ON product_section.product_code = product.code WHERE `cust_id` = '17' AND `hidden` = '0' GROUP BY `code` ORDER BY `section_id` ASC, `relative_order` ASC, `catpage` ASC LIMIT 0,30 This gives me what I want but only sometimes, at other times it randomly selects any row from the product_section table. I was hoping that by having the row I want as the last row (most recent added) in the product_section table then it would select that row by default but it is not consistent. Somehow, I need to be able to specify which row to return in the product_section table, it needs to be the row with the lowest section_id value or it should by the last row (most recent). Pulling my hair out so any help is gratefully received. customer_favourites id cust_id prod_id 70 4 469 product id code product_name hidden 469 ABC123 My Product 0 product_section id section_id catpage product_code relative_order recommended 44105 19 232 ABC123 260 1 44106 3 125 ABC123 87 1 44107 2 98 ABC123 128 1 44108 1 156 ABC123 58 0 I'm trying to delete rows in the database, based on what checkboxes are left empty by the user... What i have is small application in which a user can add an item to the database and give it tags... for example there is "apple" and it has the tags of "fruit, red, round" What i want is for the user to be able to edit those tags, so the user can remove "fruit" and add "sweet" instead or just remove "fruit" all at the same time. The code i have, somewhat works... This code below loops through the checkboxes and should remove the items that are no longer checked, by going through the database and grabbing all the tags and them checking it against those that are still checked and remove the ones that it didn't find checked...?? However whats happening is when i unchecked say "red" it removes all the other items..so if i had "red, fruit, round' and i want to remove "red" it leaves red but removes the rest. foreach($_POST['tag'] as $r=>$n){ $t = mysql_real_escape_string($_POST['tag'][$r]); $get_tag2 = mysql_query("SELECT * FROM file_cats WHERE fileID='$fileID'") or die(mysql_error()); while($t2 = mysql_fetch_assoc($get_tag2)){ $tmp_tag1 = $t2['category']; if($t==$tmp_tag1){ $remove_tag = mysql_query("DELETE FROM file_cats WHERE fileID='$fileID' AND category='$t' LIMIT 1") or die(mysql_error()); } } } This following piece of code just adds a new tag...however i want it to check to see if that tags already exist in the database, if it does then don't add it just add the new ones.. foreach($_POST['tag'] as $k=>$l){ $tag = mysql_real_escape_string($_POST['tag'][$k]); $add_tag = mysql_query("INSERT into file_cats (fileID, category) VALUES('$fileID', '$tag')") or die(mysql_error()); } My final problem is that i can't remove items if the second snippet of code is there, i have to remove those lines of code in order to remove items, however i can add items with both loops there. I'm basically stuck and hope that someone here can shed some light on what i'm doing wrong, because i know i'm doing something wrong i just can't find it Anyway thank you in advanced I use this this same exact delete for users to delete their own account with no problem for some reason this code below is deleting all my rows in each table Code: [Select] <?php if(isset($_POST['delete'])) { // this is a check box you need to check in order to confirm if(empty($_POST['confirm'])){ echo "You need to check confirm"; }else{ mysql_query("DELETE FROM `users` WHERE `goauld`= ".(int)($_POST['delete_goauld'])); mysql_query("DELETE FROM `game` WHERE `goauld`= ".(int)($_POST['delete_goauld'])); echo "$delete_goauld was deleted<br />\n"; } } ?> I have a mysql table that looks like this: id int(11) autoincrement artist varchar(50) title varchar(50) I need to check for any rows that have the same titles. So for example, if I had the following rows: 1 - Bob - Hello World 2 - Charlie Brown - Theme Song 3 - Joe - Hello World 4 - Joe - Is Cool 5 - Bob - Magic Dude The query would display Row 1, and Row 3 as duplicates. Any idea how I can do something like this? |
