PHP - Add, Delete Rows In Database Using Checkboxes
Hey everyone i having some trouble updating records in my databse using checkbox from a form.
I can update the records, but i can't figure out how to remove records at the same time. I've posted the code that i'm using to update below foreach($_POST['tag'] as $k=>$l){ $tag = mysql_real_escape_string($_POST['tag'][$k]); $check_tags = mysql_query("SELECT * FROM file_cats WHERE category='$tag'") or die(mysql_error()); $num_tags = mysql_num_rows($check_tags); if($num_tags==0){ $add_tag = mysql_query("INSERT into file_cats (fileID, category) VALUES('$fileID', '$tag')") or die(mysql_error()); } } This code inserts new records based on what the user checked. If it exist it won't add a new row, if it doesn't exist then it will add a new row. but like i said how can remove a row if the box is no longer checked? I've tried using foreach(empty($_POST['tag'] as $k => $l){ $tag = empty($_POST['tag']['$k']; } But that didn't work basically nothing was deleted. Has anyone done something like this before? if so i would appreciate any help you could give Similar TutorialsHi, I have created a table named multipath with database name "mydatabase".. I have created a table to store the data in the tables. Check boxes are created to select one row each to delete. But I am unable to delete the rows. Why?? Here's my PHP code <?php $host="localhost"; // Host name $username="root"; // Mysql username $password=""; // Mysql password $db_name="mydatabase"; // Database name $tbl_name="multipath"; // Table name // Connect to server and select databse. mysql_connect("$host", "$username", "$password")or die("cannot connect"); mysql_select_db("$db_name")or die("cannot select DB"); $sql="SELECT * FROM $tbl_name"; $result=mysql_query($sql); $count=mysql_num_rows($result); ?> <table width="400" border="0" cellspacing="1" cellpadding="0"> <tr> <td><form name="form1" method="post" action=""> <table width="400" border="0" cellpadding="3" cellspacing="1" bgcolor="#CCCCCC"> <tr> <td bgcolor="#FFFFFF"> </td> <td colspan="4" bgcolor="#FFFFFF"><strong>Delete multiple rows in mysql</strong> </td> </tr> <tr> <td align="center" bgcolor="#FFFFFF">#</td> <td align="center" bgcolor="#FFFFFF"><strong>Path ID</strong></td> <td align="center" bgcolor="#FFFFFF"><strong>Path</strong></td> </tr> <?php while($rows=mysql_fetch_array($result)){ ?> <tr> <td align="center" bgcolor="#FFFFFF"><input name="checkbox[]" type="checkbox" id="checkbox[]" value="<? echo $rows['id']; ?>"></td> <td bgcolor="#FFFFFF"><?php echo $rows['path_id']; ?></td> <td bgcolor="#FFFFFF"><?php echo $rows['path']; ?></td> </tr> <?php } ?> <tr> <td colspan="5" align="center" bgcolor="#FFFFFF"><input name="delete" type="submit" id="delete" value="Delete"></td> </tr> <? // Check if delete button active, start this if($delete){ for($i=0;$i<$count;$i++){ $del_id = $checkbox[$i]; $sql = "DELETE FROM $tbl_name WHERE id='$del_id'"; $result = mysql_query($sql); } // if successful redirect to delete.php if($result){ echo "<meta http-equiv=\"refresh\" content=\"0;URL=delete.php\">"; } } mysql_close(); ?> </table> </form> </td> </tr> </table> Please u can reply me at sawyerford007ATgmail DOTcom <body> <?php

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! Hi, I want to build into my html table that populates my database table to have a column for checkboxes with a delete button that takes the user to another page to confirm the deletion by outputting a message: Are you sure you want to delete ____, followed by a for loop to see how many checked records to get its ID in order to get its appropriate name. So I have a submit button with name attribute of "delete0" and the values of the input type of checkbox is $row['ID'], for some reason, I get the notice: "Notice: Undefined index: modifyArray in C:\display.php" and modifyArray is the name I give to the checkbox attribute (please see this in my display.php below) Here is my display.php Code: [Select] <table border="border"> <!--NB: checkbox form for multiple delete/update/insert--> <form method="post" action=""> <input type='submit' value='DELETE' name='delete0' /> <?php session_start(); require 'bellSessionDisconnect.inc'; require 'bellConnect.inc.php'; $result=mysql_query("SELECT ID, Image, Name, Manufacturer, Price, Description, SimSupport FROM bellProducts"); //phpinfo(); //NB: print table headings if(mysql_num_rows($result))//if there is at least one entry in bellProducts, make a table { //$counter+=1; print "<table border='border'>"; print "<tr> <th>ID</th> <th>Select entries to modifiy</th> <th>Image</th> <th>Name</th> <th>Manufacturer</th> <th>Price</th> <th>Description</th> <th>SimSupport</th> <th colspan='2' align='center'>Modify</th> </tr>"; //NB: now output each row of records while($row=mysql_fetch_assoc($result)) { //extract($row); "<tr align='center'> <td>$row[ID]</td> <td><input type='checkbox' name='modifyArray[]' value='$row[ID]' /></td> <td>"; if(!empty($row['Image'])) { $curImage=$row['Image']; } else if(empty($row['Image'])) { $curImage='fileUploadIcon.jpg'; //$title="please upload item image"; } print "<img src=$curImage width='70px' height='90px' /> </td> <td> $row[Name] </td> <td> $row[Manufacturer] </td> <td> $$row[Price]</td> <td align='left'>$row[Description]</td> <td>$row[SimSupport]</td> <td><a href='bellUploadForm.php?ID=$row[ID]'>UPLOAD IMAGE</a></td> <td><a href='bellUpdateForm.php?ID=$row[ID]'>UPDATE</a></td> </tr>"; //}//END INNER IF }//END WHILE }//END BIG IF ?> <?php if(array_key_exists('delete0', $_POST)) { $modifyArray=$_POST["modifyArray"]; if(!empty($modifyArray)) { header("Location: http://localhost/bellDeleteForm.php"); exit(); } } ?> </form> </table> I will worry about redirecting to bellDeleteForm.php to confirm the records the user wants to delete after I get this going, please help!!! thanks Hi,
I wish to find out is there any possible that I can delete some data inside my php website but inside my sql database, the record will still at there?
Thank you.

I have a very tricky php problem here. At least for me. On a page that is editing a job entry. I have a database generated group of checkboxes some of which have been checked when the job was entered. So the script has to do two things generate the complete list of checkboxes and check the ones that have already been selected in the job request. The below script is what I've done trying to figure it out. Description of what I'm trying to do: I'm generating the the boxes with a call to my database for the list of checkboxes. Then I'm building an array with all the possible items that could be checked to compare against. Ok here is where I think my first problem is. I need to make a second query to another table "worklog" in the same database. This is where the list of checked items are stored. What is the best way to do this? A second query seems wrong "or at least not efficient" Code: [Select] <div class="text">Job Type (<a class="editlist" href="javascript:editlist('listedit.php?edit=typelist',700,400);">edit list</a>):</div> <div class="field"> <?PHP $connection=mysql_connect ("localhost", "user", "password") or die ("I cannot connect to the database."); $db=mysql_select_db ("database", $connection) or die (mysql_error()); $query = "SELECT type FROM typelist ORDER BY type ASC"; $sql_result = mysql_query($query, $connection) or die (mysql_error()); $i=1; echo '<table valign="top"><tr><td>'; while ($row = mysql_fetch_array($sql_result)) { $type = $row["type"]; if ($i > 1 && $i % 26 == 0) echo '</td><td>'; else if ($i) echo ''; ++$i; $aTypes = array ("Spec Ad Campaign", "100 x 100 Logo", "100 x 35 (Featured Developer/Broker)", "100 x 40 (Featured Lender)", "120 x 180 (Home Page Auto)", "120 x 45 (Half Tile - Jobs)", "120x60 (Section Sponsor)", "125 x 40 (Profile Page logo)", "135 x 31 (Autos)", "135 x 60 (Autos)", "135 x 60 (Logotile - Jobs)", "150 x 40 (Auto Logo)", "160 x 240 (monster tile)", "160 x 400 (Skyscraper)", "160 x 600 (Tower)", "170x30 (Section Sponsor)", "240 x 180 JPG/GIF Auto Video", "240 x 180 size FLV video ", "300 x 250 (Story Ad)", "300 x 600 (Halfpage)", "468 x 60 (Banner Jpg/Gif)", "728 x 90 (Leaderboard)", "95 x 75 (Sweeps Logo) ", "Agent Profile Page", "Contest", "Creative Change", "Employer Profile", "Holiday Shop", "Home of the Week", "HP Half Banner (234 x 60 Static)", "Mobile Ads (320x53 *300x50*216x36*168x28)", "Newsletter", "Peelback", "Pencil Ad", "Print", "Real Deals", "Resize ad campaign", "Roll-Over Skyscraper", "Site Sponsor logo (170x30)", "Splash Page Production", "Travel Deals Update", "Video Ad", "Web Development", "Web Maintenance", "Web Quote (or Design)"); $dbTypes = explode(',',$row['type']); foreach ($aTypes as $type){ if(in_array($aType,$dbTypes)){ echo "<input style='font-size:10px;' name='type[]' type='checkbox' value='$type' CHECKED><span style='color:#000;'>$type</span></input><br/>"; }else { echo "<input style='font-size:10px;' name='type[]' type='checkbox' value='$type'><span style='color:#000;'>$type</span></input><br/>"; } } } echo '</td></tr></table>'; ?> </div> in my code i have $query = "DELETE " . $DBPrefix . "bids WHERE auction = " . $Auction['id']; $system->check_mysql(mysql_query($query), $query, __LINE__, __FILE__); but if WHERE auction = " . $Auction['id'] doesnt match anything i returns the error Quote You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'WHERE auction = 8' at line 1 I really dont understand why its returning an error is this just a case of having to add some code to check if theres anything that actualy needs deleting first? Can I use php to delete multiple rows that have a checkbox selected. I'm not sure how to go about doing this. Any suggestions? I have a table with several fields, one of which is an amount of days after which the row will be deleted. Every time the script is run, I want to check for old entries and delete them. How would I do this? Hey Guys. I have tried looking this up on Google but the only answers I am finding is using there where clause. I wanted to know if I can update or delete a range of rows like from id 100-200. Is there a way to do that? Thanks!
Hello all, im new to this forum, im a noobie, just started coding about 3 weeks ago, don't be too hard on me.
My question is I wan't to check for challenges a user's team posted that have not been excepted after 1 day, then auto refund the user's team back there credits, and then also delete all the challenges. So far here is my code.
//Delete all matches not accepted after 1 day
$arrayin = array();
$autorefund = mysql_query("SELECT * FROM `challenges` WHERE `a` = " . $team['id'] . " "
. "AND `accepted` = 0 AND `completed` = 0 AND `chtype` = 1 AND (`expires` < " . ((int) time()) . ")");
if (mysql_num_rows($autorefund) > 0) {
while ($autorefund = mysql_fetch_assoc($autorefund)) {
$arrayin[] = $autorefund['id'];
mysql_query("UPDATE `teams` SET `balance` = `balance` + " . $autorefund['credits'] . " "
. "WHERE `id` IN (" . mysql_real_escape_string(implode(',', $arrayin)) . ")");
mysql_query("DELETE FROM `challenges` WHERE `a` IN "
. "(" . mysql_real_escape_string(implode(',', $arrayin)) . ") "
. "AND `accepted` = 0 AND `completed` = 0 AND `chtype` = 1 "
. "AND (`expires` < " . ((int) time()) . ")");
}
}
FYI here is the code i had, it works fine, however it will only delete 1 challenge per team, not all of there challenges.
$autorefund = mysql_query("SELECT * FROM `challenges` WHERE `a` = " . $team['id'] . " AND `accepted` = 0 AND `completed` = 0 AND `chtype` = 1 AND (`expires` < ".((int)time()).")");
if (mysql_num_rows($autorefund) > 0) {
while ($autorefund = mysql_fetch_assoc($autorefund)) {
if ($autorefund['accepted'] == 0 and $autorefund['expires'] < time()) {
mysql_query("UPDATE `teams` SET `balance` = `balance` + " . $autorefund['credits'] . " WHERE `id` = " . $team['id'] . "");
mysql_query("DELETE FROM `challenges` WHERE `a` = " . $team['id'] . " AND `accepted` = 0 AND `completed` = 0 AND `chtype` = 1 AND (`expires` < ".((int)time())."));
}
}
}
I inherited this script, its using deprecated statements, i know im not skilled to rewrite the entire site to use prepared statements.Hi people. I have a form which inputs into a database. Here is the code that inserts a yes no option... Code: [Select] <select name = "consent"> <option value = "Yes" <?php if ($_POST['consent'] == 'Yes') { echo 'selected="selected"'; } ?>>Yes</option> <option value = "No" <?php if ($_POST['consent'] == 'No') { echo 'selected="selected"'; } ?>>No</option> </select> However, I have been asked if I can make it a yes or no checkbox instead. Please can you tell me how I need to code it so that the "yes" or "no" is recorded in the DB. At the moment I just have this Code: [Select] <input name="consent" type="checkbox" value="Yes" />Yes<br /> <input name="consent" type="checkbox" value="No" />No<br /> Thanks in advance VinceG I use the following code to generate a scrollable checkbox list of options: Code: [Select] <html> <form action="SCRIPT.php"> <?php $expList = array('Engineering ','Science', 'Art', 'IT', 'Electronics', 'Communications'); sort($expList); $tmp = array(); $i = 1; $tmp[] = '<ul style="height: 95px; overflow: auto; width: 200px; border: 1px solid #480091; list-style-type: none; margin: 0; padding: 0;">'; foreach ($expList as $option) { $tmp[] = '<li id="li' . $i . 'b"><label for="chk' . $i . 'b"><input name="chk' . $i . 'b" id="chk' . $i . 'b" type="checkbox" onchange="Enable(\'chk' . $i . 'b\',\'li' . $i . 'b\')">' . $option . '</label></li>'; $i++; } $tmp[] = '</ul>'; echo implode("\n",$tmp) . "\n"; ?> <input type="submit"> </form> </html> But there are in fact over 50 options (not just 6) and they are in fact stored in an array $expList in an external php file called LISTS.php. As you can see, the checkbox list consists of checkboxes chk1b, chk2b, chk3b, etc. with associated labels (Art, Communications, Electronics, etc.). What I need in SCIPT.php is code that will insert each of the labels where the associated checkbox has been checked in my MySQL database. E.g. in this particular case: if chk1b & chk3b have been checked, 'Art' & 'Electronics' will be inserted. Also, I want the label of the first checked checkbox to be inserted in the (database) table column 'Exp1', the 2nd one in 'Exp2'.........25th one in 'Exp25' (I already have a script that allows a maximum of 25 checkboxes to be checked). I'm guessing some sort of 'foreach' loop is required, but I can't quite work it out. Pls help! Many thanks! Hi guys, I am recent working on my php to delete the information in a database. When I insert the value in the url bar something is like: www.mysite.com/delete.php?myfavorites=what ever it is&user=test. When I inserted the value in the url bar, it did not search for the value in a database to delete it while match with the username in the url bar. Code: [Select] <?php session_start(); define('DB_HOST', 'localhost'); define('DB_USER', 'mydbuser'); define('DB_PASSWORD', 'mydbpass'); define('DB_DATABASE', 'mydbname'); $link = mysql_connect(DB_HOST, DB_USER, DB_PASSWORD); if(!$link) { die('Failed to connect to server: ' . mysql_error()); } $db = mysql_select_db(DB_DATABASE); if(!$db) { die("Unable to select database"); } function clean($var){ return mysql_real_escape_string(strip_tags($var)); } $favorites = clean($_GET['favorites']); $username = clean($_GET['user']); if($favorites == '' && $username == '') { // both are empty $errmsg_arr[] = 'Favorites are missing.'; $errflag = true; if($errflag) { $_SESSION['ERRMSG_ARR'] = $errmsg_arr; echo implode('<br />',$errmsg_arr); } else { $insert = array(); if(isset($_GET['favorites'])) { $insert[] = 'favorites = \'' . clean($_GET['favorites']) .

Any advise would be much appreciated. Thanks, Mark Hi guys, I need a bit of your help. I have successfully deleted a row in a database after I have inserted the value name with a var function that match with a username in the url bar. Now I would like to delete more than one row, but I don't know how to do this? What I am trying to achieve is to enter the url something like this: www.mysite.com/delete.php?favorites=the value1&use=test It will search for a value in the database and then delete it. But if I add the &favorites=the value2 or more than 2, then search for the values in each row while looking for a username before delete the rows Here's the current code: Code: [Select] <?php session_start(); define('DB_HOST', 'localhost'); define('DB_USER', 'mydbuser'); define('DB_PASSWORD', 'mydbpass'); define('DB_DATABASE', 'mydbname'); $errmsg_arr = array(); $errflag = false; $link = mysql_connect(DB_HOST, DB_USER, DB_PASSWORD); if(!$link) { die('Failed to connect to server: ' . mysql_error()); } $db = mysql_select_db(DB_DATABASE); if(!$db) { die("Unable to select database"); } function clean($var){ return mysql_real_escape_string(strip_tags($var)); } $favorites = clean($_GET['favorites']); $username = clean($_GET['user']); if($favorites == '' && $username == ''){ // both are empty $errmsg_arr[] = 'Both name and email are missing. You must enter one or the other.'; $errflag = true; } if($errflag) { $_SESSION['ERRMSG_ARR'] = $errmsg_arr; echo implode('<br />',$errmsg_arr); } else { $insert = array(); if(isset($_GET['favorites'])) { $insert[] = 'favorites = \'' . clean($_GET['favorites']) . '\''; } if(($favorites) && isset($username)) { mysql_query("DELETE FROM favorites WHERE username='$username' AND favorites='$favorites'"); $deleted = mysql_affected_rows(); if($deleted > 0) { echo "favorites rows is deleted"; } else { echo("favorites are already deleted"); } } } ?> Any advice would be much appreciated. Thanks, Mark I'm working on an old cms I built a few years ago and for some reason my Delete page isn't working. It has to be something simple I'm overlooking. The database connection is made just above this code and is pulling the thumb and title listed by id. When I push delete I'm getting the cmd=delete&id=2 passed on so something is up with my last if statement (I think). Here is the code: if(!isset($cmd)) { //display all the news $result = mysql_query("select * from verizon order by id"); //run the while loop that grabs all the news scripts while($r=mysql_fetch_array($result)) { //grab the title and the ID of the enws $title=$r["title"];//take out the title $id=$r["id"];//take out the id $thumb=$r["thumb"]; echo "<div id='delete'> <table> <tr> <td width='350px'><strong>$title</strong></td><td><a href='verizondelete.php?cmd=delete&id=$id'> Delete</a></td> </tr> <td colspan='2' align='center'><img src='../upload/verizon/$thumb'></td> </table> </div><br />"; } } if($cmd=="delete") { $sql = "DELETE FROM verizon WHERE id='$id'"; $result = mysql_query($sql); echo "<h1 style='text-align:center;'>deleted!</h1>"; } } ?> |
