Delete multiple rows in mysql

[andrew_biggart]

im trying to use the following code to delete some of my site users in my admin section can anyone see any reason why it isnt working?

 

thanks in advance

 

<?php

$host="localhost"; // Host name

$username=""; // Mysql username

$password=""; // Mysql password

$db_name="test"; // Database name

$tbl_name="test_mysql"; // 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>

<?

// 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_multiple.php

if($result){

echo "<meta http-equiv=\"refresh\" content=\"0;URL=delete_multiple.php\">";

}

}

mysql_close();

?>

</table>

</form>

</td>

If you use mysql_error() after your queries, it would show you any error.

Where do you set $delete?

 

// 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);

}
