issue using jquery/javascript submit() to send form to php

Hello,

I'm trying to use the javascript submit() to submit my form from my dialog window instead of using the input submit button in the form.  The form never gets submitted when I call the  $("#uploadFrm").submit(); any suggestions?

<?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");
      }
?>

lines of interest are:

105 - 111:  form input buttons. Button with an id="upload" is the one that I attach the .click event to and launches my dialog window.  In that dialog window, I have a save button that calls the javascript form submit.

84:  javascript form submit called

I am not sure why the submit isn't working but you can try replacing

$("#uploadFrm").submit();  

with

$("#submit").click();

which should submit the form

The problem seems to be in line 6.  The isset($_POST['submit'] isn't true when I do a submit from the javascript side but it's true when I click a submit button in the browser

SilhouetteCommented:
isset($_POST['submit']) checks to see if there is a value for 'submit' which only happens if you press a button with the name 'submit'.
A better options is to check
    if(isset($_FILES['image']['name']) && $_FILES['image']['name'] != ''")
This will show you if a file has been uploaded
