php form multiple input

Question

I have a PHP page with a list of items pulled from a database. Each item has an input form next to it, and right at the bottom, a submit button.

How can i do a POST check to find out which inputs have had data added? I can get the data, but how do I know the names of the particular inputs that have been filled?

" Each item has an input form next to it" Is it input form or input box ? — Prasad Rajapaksha

Iterate over $_POST and list the keys which have nonempty values.

foreach ($_POST as $key => $value) {
  if (!empty($value)) {
    echo $key . " was filled in.";
  }
}

Take a look at the isset() function of PHP - http://php.net/manual/en/function.isset.php.

For Example,

<?php
if(isset($_POST['somevar'])) {
    // if the value has been set, this code is executed
} else {
 //value not set, so execute this code.

}
?>
