将数组从字段发送到javascript，然后发送到php

Question

Im stuck with a ajax function im creating. Here is the deal, I have a form that i am sending to php via ajax. In my form i have another form that is uploading images and stores the url in a new created inputfield array. My problem is i dont know how to send these new fields to the php from ajax/jquery

here is some of the code

The uploaded file is working great and i get a new field from every uploaded file into my existing form.

<input name="img[]" type="hidden" value="mynewfile1.jpg">
<input name="img[]" type="hidden" value="mynewfile2.jpg">
etc...

Im declaring the other form objects like this and then sends them to my php file like this

Declaring

var event_title = $('input[name=event_title]');
var event_tags = $('input[name=event_tags]');

//This is my array im also trying to send to php but how?

var event_img = $('input[name=img[]]');

Sending This is done by regular ajax via POST method.

var data = 'event_title=' + event_title.val() etc...

My php

$event_title =  $_POST['event_title'];
$event_url =  $_POST['event_url'];
etc..

Here im getting the stuff from ajax and then using the variables to post and do other stuff.

Im getting the image array like this

if ($_POST['event_img']) {

  $array=$_POST['event_img'];
  foreach ( $array as $value ) {

etc...

My guess is that the problem lies in the sending from ajax, how do i fetch a array field declare it in javascript and send it to php and handle it there?

Thanks for any thoughts and help!!

Answer 1

I would use .serialize() to serialize the entire form and send it on with ajax

var data = $('form').serialize();

then if you send data with your ajax, all the current form data will be available as if you actually submitted the form.
