please, what is my mistake here?
<?php
// This function will run within each post array including multi-dimensional arrays
function ExtendedAddslash(&$sql){
foreach($sql as $sql){
// check if $var is an array. If yes, it will start another ExtendedAddslash() function to loop to each key inside.
is_array($sql) ? ExtendedAddslash($sql) : $sql=addslashes($sql);
}
}
// Initialize ExtendedAddslash() function for every $_POST variable
ExtendedAddslash($_POST);
if ($_POST["submit"]==true)
echo'you submitted this form';
else{
