Retrieving data from form arrays

[Thierry]

I have a form in which several fields share the same name via an array (<input name="cookie[]" id="cookie[]">).

 

I've been trying to use 'document.getElementById("cookie")[0]' and also 'document.getElementById("cookie[0]")', but neither yield any results.

 

Anyway of getting the field object while its a form array? (The error I get: "Object expected");

name="cookie[]"

 

the name is cookie[] not the id, getElementById is only for searching elements with id's.

and you may be tempted now to try set id's for all your input elements called 'cookie[]', but ids have to be unique (cant have many elements with all their ids called 'cookie[]');

hence why u must use the name attribute like you are doing so php knows its an array when you submit...

 

You need to access the values via getting the elements in the form.

document.forms[0]['cookie[]']

or

document.forms['nameOfForm']['cookie[]']

 

or

document.forms[0].elements['cookie[]']

or

document.forms['nameOfForm'].elements['cookie[]']
