forms and arrays

[Anon]

Hi

I've got a form as below, I tried to join up the values of the checked boxes into an array. Where could have I gone wrong ?

<input type="checkbox" name="interests[0]" value="XXX">
<input type="checkbox" name="interests[1]" value="ETC">

I'd like to join some the interests[x] into $interests. As I'd be inserting into the db through http post vars of interests.

I've tried this..

$interests = array("interests[0]", "interests[1]");

But when I posted form checking both boxes. I got 'Array' as the input into the db. 🙁

change interests[0] and [1] --> [].

does 'checkbox' input has value? You cannot set value for it - you can set 'checked' if you want it to be checked and in this case it will return 'on' as a value. So, your array can contain only names of these checkboxes and their states 'on' or 'off'. Am I wrong?

Well, Yes! ;-)

For the name of the checkboxes, you need to assigned it to an array, i.e.

name=array[]

AS for the values, you can assign them to anything you like.

<input type=checkbox name=array[] value=apple> Apple

<input type=checkbox name=array[] value=orange> Orange

<input type=checkbox name=array[] value=lemon> Lemon

When this form is submitted, you will need code to handel this array. Here is an example:

$fruit = implode($array, ",");

Result will be (if all checked) ->
apple,orange,lemon

Cheers,

Thanks, but I still cannot understand why it works. It is written in any HTML manual that checkbox has no value... But anyway, it is very helpful for me for earlier I've solved this problem in a slightly more complicated way.
