javascript - PHP doesn't process the form -

i'm having little problem here.
have form jquery disables submit input when form submited.
the problem is: use php process data when input submit clicked. apparently button being disabled first, php can not perform processing. need find way prevent this, take in code snippets:

<form class='send' action='{$_server['php_self']}' method='post'>     <!--form data-->     <input type='submit' name='finish' value='send'/> </form> 

jquery function disable:

$('.send').on('submit', function() {     $(this).find('input[type="submit"]').prop("disabled", true); }); 

and php code process:

if(isset($_post['finish'])) {     //do things } 

as said, php don't process form because js disabled button prevent multiple submitions. how process php before disable button? thanks!

since disabling submit button not send on to server in $_post variable code doesn't work, have said.

another way looking create hidden html input

<input type="hidden" name="form"> 

then when check if form send, use

if(isset($_post['form'])) {     //do things }
