[SOLVED] Post and valadation.

[redarrow]

advance thank you.

 

if i got a huge form and i want to make a condition using $_POST and

only let it update the database if there no $warning.

 

is it ok using it this way or not.

 

<?php
foreach($_POST as $key=>$val){

if(empty($val)){

echo"<div style='font-size: 36; color: #FF0000; text-align: center;'> PLEASE USE ALL THE FORM!</div>";

$warning="stop";

break;

}
}	

if(!$warning){

//do somethink

}
?>

Something like this would probably be better:

 

$requiredFields = array('field1', 'field2', 'field3' /* etc. */);
$missingFields = array();

foreach ($requiredFields as $field) {
if (!isset($_POST[$field]) || empty($_POST[$field])) {
	$missingFields[] = $field;
}
}

if (count($missingFields)) {
echo 'Please fill out the remaining fields: ' . join($missingFields, ', ');
// show form
}
else {
// process form
}

 

That'll be more user friendly seeing as you give feedback about which fields they are missing. This will be especially helpful considering that the form is "huge". It would also allow you to have optional fields should you decide that at a later point.
