Appending multidimensional array to form data

Question

Ok I'm trying to append data to an existing form when someone submits it.

function submitCustOpts() {
var custoptsids=new Array(".implode(",",$optids).");
var pfrm=document.forms['promotion".$promo_data["promo_id"]."'];
for(var i in custoptsids) {
 selectedVal = $('#'+custoptsids[i]).val();
 var input = $('<input>').attr(
 {
 type: 'hidden',
 name: 'cf_'+custoptsids[i],
 value: selectedVal
 }).appendTo(pfrm);
}
pfrm.submit();
}

EVERYTHING works. So just ignore the first half. The part I can not get it the appending to the form. The custoptsids[i] holds the id and the selectedVal holds the value. It's all working dandy, but I need to put this in a multidimensional array. Right now it submits like this:

<!-- REQUEST: Array
(
 [promo_id] => 164792
 [station_id] => 2478
 [lang] => en
 [cf_28] => 55
 [cf_29] => 61
 [PHPSESSID] => 375ee178f5de3blahblahblah
)
-->

When it should look like this:

<!-- REQUEST: Array
(
 [promo_id] => 164792
 [station_id] => 2478
 [lang] => en
 [cf] => Array
 (
 [28] => 55
 [29] => 60
 )
 [PHPSESSID] => 375ee178f5de3blahblahblah
)
-->

So my question is how do I put those values into the cf array.. cf_28 should be just cf with 28 and 29 as the array keys for the inner array..

• sixFingers: Maybe i'm missing somehing, but shouldn't "name: 'cf_'+custoptsids[i]" be instead "name: 'cf['+custoptsids[i]+']'"?
• Peanut: Omg... You are the BEST!!!!!!! Thank you! I can't believe I overlooked that. I guess that's what you get for programming for 9 straight hours x_x
• Peanut: Do you want to go ahead and answer it and I'll mark you answer correct? =)

Answer 1

I'm happy to help, also if you were really a step from the "solution". The solution would be "pause for a while", "have a coffee/tea", go back to code. But anyway:

var input = $('<input>').attr(
{
 type: 'hidden',
 // name: 'cf_'+custoptsids[i], <- look twice :)
 name: 'cf['+custoptsids[i]+']',
 value: selectedVal
}).appendTo(pfrm);

Its the same for me. EVERY time. Glad I could help.

• Peanut: Thank you again <333 Yeah I haven't taken my lunch yet, but I'm eating now =) I never seem to take breaks until I get it working, but I should try and do that more often :P
