checkboxes to an array

[EddieFoyJr]

Seems like a lot of people have problems with checkboxes. I did a search and the forum is replete with them but, either the problem doesn't relate to mine, or the "solutions" don't work.

I have a list of checkboxes. The name is being pulled up from a database. Each checkbox has the value 1 and looks like this...

<input type=checkbox name=assnid$assnarray[assnid] value=1>

or...peaking at the HTML (minus all the irrelevent stuff), the list looks like this

<input type=checkbox name=assnid1 value=1>
<input type=checkbox name=assnid2 value=1>
<input type=checkbox name=assnid3 value=1>
and so on...

Anybody know how can I post the selected checkboxes into $assnidarray where, assuming all are chosen, $assnidarray would be (1,2,3,...)?

I think you are talking about something that would look more like this.

<input type=checkbox name=assnid[$assnarray[assnid] ]value=1>

<input type=checkbox name=assnid[1] value=1>
<input type=checkbox name=assnid[2] value=1>
<input type=checkbox name=assnid[3] value=1>

would equal

array
(
0 => 1
1 => 1
2 => 1
)

if all were selected

but that's not what I was referring to. I want to parse the data into an array of the assnid$assnarray[] values for the selected boxes. I'm not really interested in the "1" values and wouldn't it be implicit anyway due to the fact it's been checked? The array I'm after would be (0,1,2...)

Actually, the array would equal

array
(
1 => 1
2 => 1
3 => 1
)

You assigned the keys [for some reason] in the form. Even if only the first and last were selected, then you'd have access to the keys $POST['assnid']['1'] and $POST['assnid']['3']

Unless you need to, I wouldn't assign keys to the array.

<input type=checkbox name=assnid[] value="whatever">
<input type=checkbox name=assnid[] value="whatever">
<input type=checkbox name=assnid[] value="whatever">

Then to loop through the array (for EddieFoyJr), you could use a foreach loop

foreach($_POST['assnid'] as $key => $value) {
   echo "Key: " . $key . " Value: " . $value . "<br>";
}

Where $key would be 0 1 2 3 and so on (the array key), and $value would be the value that each key holds.

Thanks for the try but it only gives me: Parse error: parse error, unexpected T_STRING.

I think this question probably goes beyond the scope of this Forum. If there are any hired guns out there who actually have a clue on how to modify a PostNuke module, please send me a private message so we can connect. Thanks.

Well, since the example started at one, the keys would be 1, 2, 3; not 0, 1, 2 (as cgraz noted).

I take it that the array keys are what you're after (and that you don't really care about the values, 'cos they're all 1s anyway). That would be [man]array_keys[/man]
