Refering to form elements with PHP

[cineplex]

With Javascript, we can do stuff like this:

window.document.forms[n].elements[n] .....

to refer to form elements.

Is there a similar approach to refering to elements with PHP?

Thanks.

Depends on what you mean. If you mean accessing data input by the user in a form, search the forums for $POST and $GET.

If you want to access elements of a form before they are posted, PHP can't do that. Because PHP is a sever-side language, you cannot access elements of HTML in the same way you can with Javascript. Form validation before submission, etc. should be performed by Javascript snippets, not by PHP.

EXAMPLE

If the user submits an entire page. Can I cycle through all the HTTP_POST_VARS posted from a page. Sort of like using HTTP_POST_VARS as an array?

HTTP_POST_VARS IS an array in itself, you can loop thru it like this:

<?
foreach($HTTP_POST_VARS as $varName => $value)
{
echo "Variable: " . $varName . " Value: " . $value . "<br>";
}
?>
