Question

I am using JQuery and SimpleModal Confirm Modal Dialog to show a confirm box before uploading. The form is submitting fine but as i’m checking isset submit button in PHP therefore it fails. How could i submit post using JQuery with setting submit button.
Here is the code

HTML

<form enctype="multipart/form-data" action="#duc" method="post" id="uploadform" >
    <input name="file" type="file" >
    <input name="Submit_upload" type="submit" value="Upload" id="Upload" >
</form>

JQuery

jQuery(function ($) {
  $('#Upload').click(function (e) {
    e.preventDefault();
    confirm("Continue to the Upload?", function () {
        $('#uploadform').submit();
    });
  });
})

PHP

if(isset($_POST['Submit_upload']) && $_FILES['file']['name'])
{
    // file uploading process.
}

I think as after confirm JQuery submitting the form so the actual submit button is not adding in the post array. any help will be much appreciated.

Answer 1

When you submit the form via .submit, type=submit input values are not sent at the same time. There are a ton of different ways to solve/handle this. One is to do:

<input name="Submit_upload" type="hidden" value="true">
<input type="submit" value="Upload" id="Upload">

The hidden input will be sent.
