First of all, this is extremely unsafe, you should not use this code without further safety measures!

PHP Code:
// thisfile.php

function del_entrie($entrie)
{
    
$query "DELETE FROM Brochures WHERE column = '" $entrie ."'";
    
$result mysql_query($query);
    
    if (!
$result)
    {
        echo 
mysql_error();
    }

}

if (isset(
$_GET["text"]))
{
    
del_entrie($_GET["text"]);

Now you will delete one row from the table Brochures where column has the value of $entrie.

For example:
HTML Code:
<a href="thisfile.php?text=foo">Delete me!</a>
If the user clicks that link, he will delete the entire row where ever the column "column" includes the text "foo".

If you want to do something like this, you should search this forum for "SQL injection", since that will become a big problem for you if you use code like this.
