Re: multiple select option alternative to field_name[]

Use this.form.elements['select1[]'] Terence wrote:

Dear All, The only way I know to retrieve all the values from a multiple select field is to use the square brackets after the field name ie. user_id[] The problem however is that when I use a javascript function to transfer the items from multiple_select_list1 to multiple_select_list2, I cannot use the square brackets in a field name, as this obviously conflicts with something in the script. So I am wondering if there's any other way in PHP to get the items, or do I have to find an alternative way in javascript? If anyone has ideas it would be great. Thanks Terence my code:
