Ajax form submit with file upload

Hi guys,

I’m using the built-in wordpress AJAX handler to run all of my front-end AJAX.

I currently have a contact form in place which works perfectly. Now I want to add a file upload option to it, however, by default, $_FIELS is not sent.

I’ve seen some solutions online involving either creating an iframe or implementix AjaxForm jQuery but I don’t know how to implement them properly withing WordPress.

This is my current jQuery code:

$('#request-newjob-form').on('submit', function(e){
	var formID = '#' +$(this).attr('id');
	var formParrentID = '#' +$(this).parent().attr('id');

		$('<div/>', {style:'display:none;'}).appendTo($(formParrentID)).append($('<div/>', {id:'request-form-loading', class:'fancybox-alert', text:ajax_request_submit.loadingmessage}));
		$.fancybox({href:'#request-form-loading'});
        //$(formParrentID +' p.status').show().text(ajax_request_submit.loadingmessage);

        $.ajax({
            type: 'POST',
            dataType: 'json',
            url: ajax_request_submit.ajaxurl,
            data: {
                'action': 'prp_email_newjob_aj',
				'formData' : $(formID).serialize(),
				'security' : $(formID +' #security').val(),
 		 },
            success: function(data){
				$('<div/>', {style:'display:none;'}).appendTo($(formParrentID)).append('<div id="request-form-success" class="fancybox-alert" style="max-width:560px;"><h3 class="no-margin-top">Thank you for submitting your artwork request.</h3>Please allow 12 hours for processing of your request. If you have an urgent request please contact Adriana Poglia or Rebecca Adair on 0207 420 3550</div>');
				$.fancybox({type:'inline', href:'#request-form-success'});
            },
			error: function(data){
				$('<div/>', {style:'display:none;'}).appendTo($(formParrentID)).append('<div id="request-form-error" class="fancybox-alert" style="max-width:560px;"><h3 class="no-margin-top">We have encountered an error. Please try again later.</div>');
				$.fancybox({type:'inline', href:'#request-form-error'});
			}
        });
        e.preventDefault();
    });

How should I change it?

Thank you.
