PHP - Deleting Rows With Check Boxes
I really need some huge help on deleting rows with check boxes. Im completly lost on how to do this. Read some examples online and even with the code being small to do this i cant figure it out on intergrading it with the code I wrote. sorry that the code is long on this. I have decent comments though. At the very bottom i have started writing the delete code. My problem is figuring out how to make the script know what check box is checked. I have a select all check box java script on this page too
Code: [Select] <form name="frm1" id="frm1" action="" method="post" 15.onsubmit="javascript:return submitIt('frm1')"> <p> <center> <table width="60%" border="1" cellspacing="1" cellpadding="0"> <tr align="center"> </tr> <tr align="center"> <td><input type="checkbox" name="checkAll" value="x" id="checkall" onclick="checkUncheckAll('association[]', this.checked)" /></td> <td>Recipient</td> <td>Subject</td> <td>Sent</td> <td>read/unread</td> </tr> <?php // find out how many rows are in the table $count3 = "SELECT COUNT(*) FROM sent WHERE id = '".($_SESSION['user_id'])."'";; $count2 = mysql_query($count3) or trigger_error("SQL", E_USER_ERROR); $r = mysql_fetch_row($count2); $numrows = $r[0]; // number of rows to show per page $rowsperpage = 10; // find out total pages $totalpages = ceil($numrows / $rowsperpage); // get the current page or set a default if (isset($_GET['sent']) && is_numeric($_GET['sent'])) { // cast var as int $currentpage = (int) $_GET['sent']; } else { // default page num $currentpage = 1; }// end if // if current page is greater than total pages... if ($currentpage > $totalpages) { // set current page to last page $currentpage = $totalpages; }// end if // if current page is less than first page... if ($currentpage < 1) { // set current page to first page $currentpage = 1; } // end if // the offset of the list, based on current page $offset = ($currentpage - 1) * $rowsperpage; // get the info from the db $count3 = "SELECT * FROM sent WHERE id = '".($_SESSION['user_id'])."' ORDER BY time DESC LIMIT $offset, $rowsperpage "; $count2 = mysql_query($count3) or trigger_error("SQL", E_USER_ERROR); // while there are rows to be fetched... while ($list = mysql_fetch_assoc($count2)) { // these are variables to place in the echo $sent_id = $list['sent_id']; $recipient = $list['sendto']; $subject = $list['subject']; $read = $list['read']; // grabs the time offset $take3 = "SELECT time_offset FROM users WHERE id='".mysql_real_escape_string($_SESSION['user_id'])."'"; $take2 = mysql_query($take3) or die(mysql_error()); $take1 = mysql_fetch_array($take2); $recieved = $list['time']; // adds the users time offset to the inputed time $time = ($recieved + $take1['time_offset']); // sets default time to UTC then formats the inputed time that was offset with the users offset date_default_timezone_set('UTC'); $user_offset = date('h:i:s a M/d', $time); ?> <tr> <td><center><input type="checkbox" name="association[]" id="<?php echo $sent_id; ?>" value="1" /></center></td> </label></td> <td><center><a href="search_goaulds.php?goauld=<?php echo $recipient; ?>"><?php echo $recipient ?></a></center></td> <td><center><a href="sent_view.php?sent_id=<?php echo $sent_id; ?>"><?php echo $subject ?></a></center></td> <td><center><?php echo $read ?></center></td> <td><center><?php echo $user_offset ?></center></td> </tr> <?php } // while loop ?> </table> </center> <div class="deletecontainer"> <div class="delete"> <br/> <input type="submit" name="delete" id="delete" value="Delete"></p> </form> </div> </div> <?php if(isset($_POST['delete'])) { // if checkbox is checked with the matching sent_id if(isset($_POST['sent_id'])) { // then delete sent_id matching the checkbox id mysql_query("DELETE FROM `sent` WHERE `sent_id`= '".($_POST['sent_id'])."'"); } } ?> 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> 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 "$delete_goauld was deleted<br />\n"; } } ?> I'm trying to delete rows in the database, based on what checkboxes are left empty by the user... What i have is small application in which a user can add an item to the database and give it tags... for example there is "apple" and it has the tags of "fruit, red, round" What i want is for the user to be able to edit those tags, so the user can remove "fruit" and add "sweet" instead or just remove "fruit" all at the same time. The code i have, somewhat works... This code below loops through the checkboxes and should remove the items that are no longer checked, by going through the database and grabbing all the tags and them checking it against those that are still checked and remove the ones that it didn't find checked...?? However whats happening is when i unchecked say "red" it removes all the other items..so if i had "red, fruit, round' and i want to remove "red" it leaves red but removes the rest. foreach($_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 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. How would I make a script that would delete any row in a MySQL table that was more than 7 days old? 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? Hi guys, I am trying out this code but it does not work, any idea what I am doing wrong? <?php include 'connect.php'; $tbl_name="users"; $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>Id</strong></td> <td align="center" bgcolor="#FFFFFF"><strong>Firstname</strong></td> <td align="center" bgcolor="#FFFFFF"><strong>Lastname</strong></td> <td align="center" bgcolor="#FFFFFF"><strong>Location</strong></td> <td align="center" bgcolor="#FFFFFF"><strong>Email</strong></td> <td align="center" bgcolor="#FFFFFF"><strong>Website</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"><? echo $rows['userID']; ?></td> <td bgcolor="#FFFFFF"><? echo $rows['firstname']; ?></td> <td bgcolor="#FFFFFF"><? echo $rows['lastname']; ?></td> <td bgcolor="#FFFFFF"><? echo $rows['location']; ?></td> <td bgcolor="#FFFFFF"><? echo $rows['email']; ?></td> <td bgcolor="#FFFFFF"><? echo $rows['website']; ?></td> </tr> <?php } ?> <tr> <td colspan="5" align="center" bgcolor="#FFFFFF"><input name="delete" type="submit" id="delete" value="Delete"></td> </tr> <? if($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($result){ echo "<meta http-equiv=\"refresh\" content=\"0;URL=showusers2.php\">"; } } mysql_close(); ?> </table> </form> </td> </tr> </table> I want to delete rows in a table of my database using check-box.

Hi, I am trying to figure out how to insert the following values into another table if they have a checked box:
$class_id = $_POST['class_id']; // This value is from a dropdown on the top of the page basically, each row in the table has a checkbox If the checkbox is checked then it should insert the user_id field from the checked rows and the value from a drop down (class_id) at the top of a page into another table. I have managed the code up to here but I need a tutorial or guidance to do the rest. At the moment I am getting error HTTP 500 I understand that the code is subject to sql injection, but will sort that out later Edited August 11, 2020 by PythonHelpHi, im new to php and got a simple query. i have built a web gallery and i want to add keywords to pictures, ive built the interface and mysql statements so it lists all possible keywords and creates a tick box for the user to use. ive created a table to join the image id's to my keyword id's as its going to be a many to many relationship, ive also built the sql statement below to select the highlighted image, but im not sure how i can join the looping of all keywords to generate the tick boxes and then to loop again to populate the tickboxes that are saved within the DB - if that makes sense?? SELECT * FROM images,img_key,keywords where img_key.img_id=images.id and keywords.id=img_key.key_id and images.id='2' I cannot figure out why my checkbox values are not being included in my emails I am posting my html and my php.

Hi guys On the edit profile page on my website, im trying to get is so that when the user first opens the page, if the database field reads "1" the checkbox is checked. However if the user unchecks it and makes a mistake on the form which returns an error, the checkbox remains unchecked. Also if the user unchecks the text box, the 1 in the database is changed to a 0. And vise versa. The only way i have got it to work succesfully is by using the following: <?php $test = $_POST['test']; $submit = $_POST['submit']; if (!isset($test)) { $test="0"; } else { $test="1"; } if ($submit) { mysql_query("UPDATE profiles SET test='$test' WHERE username='user'"); echo "ok"; } ?> <html> <form action="test.php" method="POST"> <input type="checkbox" name="test" <?php if ($submit) { if ($test=="1") { echo "checked='checked'";}} else { if ($row['test'] == "1") {echo "checked='checked'";}} ?> /> <input type="submit" name="submit" /> </form> </html> My problem is, i have about 60 check boxes on the page, and i dont really want to write the code below for all of them: if (!isset($test)) { $test="0"; } else { $test="1"; } Does anybody know a better way to do this so i dont end up with 420 lines of extra code? Many thanks. I was using this wonderful tutorial on dynamic check boxes and databases http://www.phpfreaks.com/tutorial/working-with-checkboxes-and-a-database . This example is uses checkboxes to give users admin rites. I have tried to revamp this code to handle more inputs from checkboxes but some where I have made some errors. <?php include("db.php"); $updated = FALSE; if(count($_POST) > 0){ $DEP = $_POST['MMARS_DEP']; array_map('intval',$DEP); $DEP = implode(',',$DEP); mysql_query("UPDATE master_roles SET MMARS_DEPT=0") or trigger_error(mysql_error(),E_USER_ERROR); mysql_query("UPDATE master_roles SET MMARS_DEPT=1 WHERE id IN ($DEP)") or trigger_error(mysql_error(),E_USER_ERROR); $MD = $_POST['MMARS_MD']; array_map('intval',$MD); $MD = implode(',',$MD); mysql_query("UPDATE master_roles SET MMARS_MD=0") or trigger_error(mysql_error(),E_USER_ERROR); mysql_query("UPDATE master_roles SET MMARS_MD=1 WHERE id IN ($MD)") or trigger_error(mysql_error(),E_USER_ERROR); $ORG = $_POST['MMARS_ORG']; array_map('intval',$ORG); $ORG = implode(',',$ORG); mysql_query("UPDATE master_roles SET MMARS_ORG=0") or trigger_error(mysql_error(),E_USER_ERROR); mysql_query("UPDATE master_roles SET MMARS_ORG=1 WHERE id IN ($ORG)") or trigger_error(mysql_error(),E_USER_ERROR); $SEC = $_POST['MMARS_SEC']; array_map('intval',$SEC); $SEC = implode(',',$SEC); mysql_query("UPDATE master_roles SET MMARS_SEC=0") or trigger_error(mysql_error(),E_USER_ERROR); mysql_query("UPDATE master_roles SET MMARS_SEC=1 WHERE id IN ($SEC)") or trigger_error(mysql_error(),E_USER_ERROR); $BOG = $_POST['MMARS_BOG']; array_map('intval',$BOG); $BOG = implode(',',$BOG); mysql_query("UPDATE master_roles SET MMARS_BOG=0") or trigger_error(mysql_error(),E_USER_ERROR); mysql_query("UPDATE master_roles SET MMARS_BOG=1 WHERE id IN ($BOG)") or trigger_error(mysql_error(),E_USER_ERROR); $SW = $_POST['MMARS_SW']; array_map('intval',$SW); $SW = implode(',',$SW); mysql_query("UPDATE master_roles SET MMARS_SW=0") or trigger_error(mysql_error(),E_USER_ERROR); mysql_query("UPDATE master_roles SET MMARS_SW=1 WHERE id IN ($SW)") or trigger_error(mysql_error(),E_USER_ERROR); $updated=TRUE; } ?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" /> <title>phpfreaks checkbox tutorial</title> </head> <body> <form action="<?php echo $_SERVER['PHP_SELF'];?>" method="post"> <?php if($updated===TRUE){ echo '<div>Privileges Updated!</div>'; } ?> <table> <tr> <th><td>DEPT</td><td>MD</td><td>ORG</td><td>SEC</td><td>BOG</td><td>SW</td></th> <?php $label = array('MMARS','LCM','NM SEC','Classic MMARS','CAPS','PMIS','WRK COMP'); $table = array('MMars','LCM', 'NMSec', 'ClassMars', 'CAPS', 'PMIS', 'WrkComp'); $i= 0; while($i < 1){ echo "<tr>" ."<td>".$label[$i]."</td>"; $array = array(); $count = 0; $Aid = mysql_query("SELECT DISTINCT id FROM DB") or die (mysql_error()); while ($row= mysql_fetch_assoc($Aid)){ $ID = $row['id']."<br>"; $array[$count] = $ID; $count++; } $Disabled =""; $sql = "SELECT id, UAID, DB_NAME, MMARS_DEPT, MMARS_MD, MMARS_ORG, MMARS_SEC, MMARS_BOG, MMARS_SW FROM master_roles WHERE `UAID`='1000' AND id <= 6"; $result = mysql_query($sql) or trigger_error(mysql_error(),E_USER_ERROR); $row = mysql_fetch_row($result); list($id, $UAID, $DB_NAME, $MMARS_DEP, $MMARS_MD, $MMARS_ORG, $MMARS_SEC, $MMARS_BOG, $MMARS_SW)= $row; $checked = ($MMARS_DEPT==1) ?

If a box is not selected I want an error message to echo. With what I've done so far, if a box is selected the form works but if one is not selected my error message does not show and I get an undefined Index Notice. Can anyone tell me where I'm going wrong. Page 1- form <form action="processPage7.php" method="post"> <br /> <p>Check the times you are most likely to have available:</p> <input type="checkbox" name="days[]" value="Evenings" <?php if(isset($_POST['days']) == 'Evenings') echo 'checked' ?>> Weekday evenings<br /> <input type="checkbox" name="days[]" value="Weekdays" <?php if(isset($_POST['days']) == 'Weekdays') echo 'checked' ?>> Week Days<br /> <input type="checkbox" name="days[]" value="Weekends" <?php if(isset($_POST['days']) == 'Weekends') echo 'checked' ?>> Weekend Days<br /> </div><br /><br /> <p><input type="submit" value="Next Page" /></p><input type="reset" value="Reset" /> </form> Page 2- <?php session_start(); if($_SERVER['REQUEST_METHOD']== 'POST'){ $valid_form = TRUE; // NO PROBLEMS if(!isset($_POST['days'])){ echo "Error, no time selected. Please go back and select a time."; }else{ $_SESSION['days'] = $_POST['days']; } if($valid_form == TRUE){ header('Location: FormProcess.php'); } } ?> And Page 3 <?php session_start(); $days = $_SESSION['days']; $chkResults = $days; for ($i = 0;$i<=count($chkResults)-1;$i++){ echo "<p>". $days[$i]; } ?> Thanks in advance. I have a set of 26 checkboxes that are stored in an array. The below code dumps the comma separated array values into a single record column. Code: [Select] // dumping the type of job checkboxes $type = $_POST['type']; var_dump($type); // Setting up a blank variable to be used in the coming loop. $allStyles = ""; // For every checkbox value sent to the form. foreach ($type as $style) { // Append the string with the current array element, and then add a comma and a space at the end. $allTypes .= $style . ", "; } // Delete the last two characters from the string. $allTypes = substr($allTypes, 0, -2); // end dumping the type of job checkboxes This works great! But my needs go past this. The record can be edited. So I need to get the values back out of the database and populate the correct check boxes for editing. The checkboxes are generated by this code. 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", "name", "pass") 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 ''; ++$i; echo "<input style='font-size:10px;' name='type[]' type='checkbox' value='$type'><span style='color:#000;'>$type</span></input><br/>"; } echo '</td></tr></table>'; ?> </div> I am having a problem getting these checkboxes repopulated. I think that a way to do this is to: Get the values out of the database in a array Compare the values the list of all possible values. Check the boxes of the values confirmed to be there. I didn't build the application so I need help to work through this problem. 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? Is it possible to check if multiple rows exist at the same time. For example, if a row with the id "1" and another row with id "2" exists, and return something like true then false if only the first exists?
I have a file that provides tens of thousands to check and it takes forever. I know this sounds bad off the start, but it's not something that is run normally. Only to update my database with new additions.
Is there any good way to check a lot at once? I know you can insert many at a time and save a lot of time.
