how to open a jquery dialog window after form is submitted

Hello,

I have a web page that uses an html submit button that submits a form to itself and runs some php code. At the end of that php code (after the form is submitted), I would like to open my jquery dialog window, but I'm unsure how to accomplish this...any ideas?

<?php
	$folder = 'images/';
	$orig_w = 500;
	$caption = $_POST[caption]; 
	$albumCoverImage = $_POST[albumCoverImage]; 
	if( isset($_POST['submit']) )
	{
		$imageFile = $_FILES['image']['tmp_name'];
		$filename = basename( $_FILES['image']['name']);
		$info = pathinfo($folder.$filename);
		$fileext = $info['extension'];
		list($width, $height) = getimagesize($imageFile);		
		$src ='';
		if (strtolower($fileext) == 'png') {
			$src = imagecreatefrompng($imageFile);
		}
		else if(strtolower($fileext) == 'gif'){
			$src = imagecreatefromgif($imageFile);
		}
		else if(strtolower($fileext) == 'jpg'){
			$src = imagecreatefromjpeg($imageFile);
		}
		else{
			echo "File type not supported, .gif, .jpg or .png required!";
		}			
		$orig_h = ($height/$width)* $orig_w;
		$tmp = imagecreatetruecolor($orig_w, $orig_h);
		imagecopyresampled($tmp, $src, 0,0,0,0,$orig_w,$orig_h,$width,$height);	
		if (strtolower($fileext) == 'png') {
			imagepng($tmp, $folder.$filename,100);
		}
		else if(strtolower($fileext) == 'gif'){
			imagegif($tmp, $folder.$filename,100);
		}
		else if(strtolower($fileext) == 'jpg'){
			imagejpeg($tmp, $folder.$filename,100);
		}
		else{
			echo "File type not supported, .gif, .jpg or .png required!";
		}
		imagedestroy($tmp);
		imagedestroy($src);
		$filename = urlencode($filename);
		header("Location: crop.php?filename=$filename&height=$orig_h");
	}
?>

Open in new window

Mrunal

have you tried this:

http://api.jquery.com/unload/

cgray1223

ASKER

The only downside to the unload function is that it gets called when the user hits back or forward button and I can't detect the difference between that action and a form submittal to the page itself. Thanks for the idea.

Mrunal

if you want to fire jquery dialog only on form submit...check this out:

Thanks for the suggestion mroonal. It got me a little closer, but I still can't resubmit the form from the dialog window.

the $('form#uploadFrm').submit(function() gets called when I click my input submit button and launches the dialog window, and then the button function on the dialog calls the .submit function again by executing $("#uploadFrm").submit() but the form doesn't get submitted even though I have a conditional that forces the function to return empty or true (tried both). If I just leave the .submit function empty it will submit. So that seems to tell me the dialog's .submit() call isn't working properly or the form is in a weird state.
