How to detect first page entry?

Hello,

On first entry of my webpage(.php) a specific function must be omitted.
On next entries (by clicking a submit button on that page) the specific
function must be executed.

How does my php file distinghuis between first entry and next entries?

I tried isset()/empty()/is_null() variable functions and $GLOBALS but all
variables seems to be cleared/reset on re-entry of the webpage.

How to solve this problem?

Thanks

Henk

You can check, wether submit button was pressed. If it was,
execute the function. (if $_POST['button_name'])

Hello,

thanks for your quick answer.

Well I was mistaken, it's not a submit button, it's a picture with an
onclick/submit event:

(A HREF=''><img Src="" OnClick="submit();"></A>

so there's no 'button_name'

Set then you have to assign a value to a hidden input by
javascript and check this value in the same way

Use sessions.

C.

if the form has method="post" you could do -


if( $_SERVER['REQUEST_METHOD'] == 'POST' ){
//
}
