jQuery Forum

Hello,

I am having a problem using the jQuery Form from www.malsup.com.  I am using the ajaxForm call as follows:


First, here is my HTML:

1. <form id="formID" action="someScript.php" enctype="multipart/form-data">
2.       <input id="textField" name="textField" type="text" />
3.       <input id="fileField" name="fileField" type="file" />
4.       <input id="submitButton" name"submitButton" type="submit" value="submit" />
   
5. </form>
   

And here is my jQuery:

1. $("#formID").ajaxForm ({
2.       type: "post",
3.       dataType: "json",
4.       iframe: true,
5.       data: {
6.             additionalDataItem1ToSubmit: "value1",
7.             additionalDataItem2ToSubmit: "value2",
8.             arrayToSubmit: someArray // This is the line causing the problem (read below for details)
   
9.       },
10.       beforeSubmit: function () {
11.       // Do something before making the submit call to someScript.php
    
12.       },
13.       success: function (data) {
14.       // Do something with the return value (data) from someScript.php
    
15.       }
    
16. });
    

Now, if I comment out line number 8 in the ajaxForm function (arrayToSubmit), everything is fine.  However, when this line is commented out and when I try to pass an array as shown in the code, then I get an error and form submission fails (please note that someArray is already initialized, and could either be an empty array or could contain some array items).

The error I receive is:

TypeError: 'undefined' is not a function (evaluating 'this._each(function(value) { iterator.call(context, value, index++); })')

I am not sure how to work around it either.  All I need is the following requirements.

1. Submit a form via jQuery (preferably using ajaxForm)
2. Use it to upload a file and other input types (such as text)
3. Also submit other information from outside the form, including an array to PHP
4. Run a simple code prior to making the submit
5. Handle a JSON response from PHP in the callback function

As you can see, everything is OK except part of step 3 of the requirements, which is the array.

Please help, and I really really thank you.
