Deleting Multiple Rows from a MySQL database with PHP
Hey,
For the past few days I've given my visitors the ability to delete multiple documents from their folder. Only recently did I realise it isn't working anymore and now it's driving me nuts. Here is the basis markup:
Code:
<?php
include("t.php");
include("u.php");
$fetchimages = mysql_query("SELECT * FROM iuplogs WHERE username = '$_SESSION[username]' ORDER BY id DESC");
?>
<form method="post" name="form">
<table width="100%" cellpadding="0" cellspacing="0">
<?
if ($_POST['delete']) {
foreach ($_POST['delete'] as $value) {
mysql_query("DELETE FROM iuplogs WHERE id = '$value'");
$fetchdelete = mysql_fetch_array(mysql_query("SELECT * FROM fuplogs WHERE id = '$value' ORDER BY id DESC LIMIT 1"));
$explode = explode("/", $fetchdelete[url]);
$filetodelete = "urs/$explode[4]";
$delete = unlink($filetodelete);
header("location: $url");
}
}
?>
<tr>
<td style="padding: 4px; padding-left: 12px;"><b>My Images</b></td>
</tr>
<?
while ($image = mysql_fetch_array($fetchimages)) {
?>
<tr>
<td><input type="checkbox" name="delete[]" value="<?=$image[id];?>"></td>
</tr>
<?
}
?>
</tr>
<tr>
<td align="right" style="padding-top: 5px;"><input type="button" value="Select All" onClick="this.value=check(this.form)" name="selectsq" /><input type="submit" value="Delete Selected" name="submit" /></td>
</tr>
</table>
</form>
<?
include("b.php");
?>
I really can't see any problem with this. For the record, here is the error message which I receive when I select "Delete Selected".
Warning: Invalid argument supplied for foreach() in /home/urload/public_html/test.php on line 10
If I didn't mark any checkboxes then I would understand why I receive this error, but even when I do select one or more checkbox(s) I still receive this. Previously, I used error_reporting(E_ERROR); to hide the message if they selected "Delete Selected" without marking a checkbox.
Any help would be very appreciated.
Thanks in advance,
