Here is the error

Warning:  Invalid argument supplied for foreach() in /home/zybersca/public_html/news/deletebeta.php on line 17

Here is the php

<?php

if( isset($_POST['submit']) )
{
    $error['2'] = true;

    if( count($_POST['box']) < 1)
    {
        $error['0'] = ture;
        $error['1'][] = "Please choose something to delete";
    }

    if( $error['0'] == false )
    {
        foreach( $_POST['box'] as $delete )
        {
            mysql_query("DELETE FROM `test` WHERE `news` = '$delete'") or die(mysql_error());
            mysql_query("DELETE FROM `test` WHERE `shout` = '$delete'") or die(mysql_error());
        }
        
        $error['1'][] = "Successfully deleted news";
    }

while( $array = mysql_fetch_assoc($query) )
{
    $content[] = "    <td> <input type=\"checkbox\" name=\"box\" value=\"{$array['news']}\" /> </td>
                <td> {$array['news']} </td>
                <td><input type=\"checkbox\" name=\"box\" value=\"{$array['shout']}\" /></td>
                <td> {$array['shout']} </td>\n";
}
echo "    <form action=\"deletebeta.php\" method=\"post\">";
echo "        <table>\n";

foreach( $content as $tds )
{
    echo "        \t<tr>
                \t$tds
        \t</tr>\n";
}

        <input type=\"submit\" name=\"submit\" value=\"delete\" />
    </form>";

foreach is for looping through an array. $_POST['box'] isn't an array, it is an item in an array.

Just forget the loop and append the $_POST['box'] where you currently have $delete.

So how would that part of the code look? im really new with PHP

I got it to not show an error but it doesn't delete when a check box is selected, and then when you just click delete it still echo's Success.

<?php
include("include/config.php");
include("include/opendb.php");

if( isset($_POST['submit']) )
{
    $error['2'] = true;

    if( count($_POST['box']) < 1)
    {
        $error['0'] = ture;
        $error['1'][] = "Please choose something to delete";
    }

    if( $error['0'] == false )
    {
            mysql_query("DELETE FROM `test` WHERE `news` = '$delete'") or die(mysql_error());
            mysql_query("DELETE FROM `test` WHERE `shout` = '$delete'") or die(mysql_error());
        }
        
        $error['1'][] = "Successfully deleted news";
    }

if( $error['2'] == true )
{
    foreach( $error['1'] as $message )
    {
        echo "$message<br />\n";
    }
}

$content = array();

$query = mysql_query("SELECT * FROM `test`");
while( $array = mysql_fetch_assoc($query) )
{
    $content[] = "    <td> <input type=\"checkbox\" name=\"box\" value=\"{$array['news']}\" /> </td>
                <td> {$array['news']} </td>
                <td><input type=\"checkbox\" name=\"box\" value=\"{$array['shout']}\" /></td>
                <td> {$array['shout']} </td>\n";
}
echo "    <form action=\"deletebeta.php\" method=\"post\">";
echo "        <table>\n";

foreach( $content as $tds )
{
    echo "        \t<tr>
                \t$tds
        \t</tr>\n";
}
echo "        </table>
        <input type=\"submit\" name=\"submit\" value=\"delete\" />
    </form>";
?>
