Arrays and form problem

[micmac]

Hi all,
I'm trying to send a form that looks like this:

if ($_POST['sendclientid'])
{
$count = count($_POST['response_check']);

for ( $i = 0; $i < $count; $i ++ )
{

$client[] = array ($_POST['response_check'][$i], $_POST['email_responses'][$i]);

}
print_r($client);
}

<form name="ifrm" action="<?php echo $PHP_SELF; ?>" method="post">
// query database for results here
    <input name="response_check[]" type="checkbox" value="<?php echo $temp_userid;?>">
    <select style="width:110px;" name="email_responses[]">
        <option value="">SELECT AN EMAIL RESPONSE</option>
        <option value="1">1<option>
        <option value="2">2<option>
        <option value="3">3<option>
    </select>
<input type="submit" name="sendclientid" value="Send Details" style="width:37px; cursor:hand;">
<form>

Lets say that there are 2 results from the db query. If i check both checkboxes and select option 1 and 3 from the select box and press the submit button i get the following output:

Array ( [0] => Array ( [0] => 1 [1] => 1 ) [1] => Array ( [0] => 2 [1] => 3 ) )

However if i only only check the second results checkbox and select an option from the select box corresponding with it i get these results:

Array ( [0] => Array ( [0] => 2 [1] => ) )

Why doesn't it pass the value for the select box?

Could you do a print_r($_POST) instead to clarify?

Thanks for the reply:
This is what i get when i check both checkbox results and select an option from the select box:

Array ( [response_check] => Array ( [0] => 1 [1] => 2 ) [email_responses] => Array ( [0] => 1 [1] => 3 ) [sendclientid] => Send Details )

This is what i get when i only check the second results checkbox and select an option from the select box corresponding to it:

Array ( [email_responses] => Array ( [0] => [1] => 3 ) [response_check] => Array ( [0] => 2 ) [sendclientid] => Send Details )

Those results imply that your conclusion that it doesnt "pass the value for the select box" is actually incorrect.

Incidentally, I only see one checkbox in the source provided.

I didn't include the query...just added a comment for brevity.

It appears to pass a blank value ie. [0] => , i am only wanting to get the second value [1] => 3 but as [0] => 3.

Array ( [email_responses] => Array ( [0] => [1] => 3 )

That I'm guessing would be the "unselected" select box - if you gave it a value of "Wibble" my guess would be that you'd see [0]=>Wibble in the results of print_r().

And of course unselected checkboxes don't become part of the form submission; so if any are unselected, the two arrays will end up out of sync.

So I think I've figured out what this form is supposed to look like: several checkbox/selection pairs.

Try explicitly indexing your fields (i.e., use [0], etc. instead of [] when you name them). Then checkbox[0] will correspond to select[0], checkbox[1] will correspond to select[1] and so on; if checkbox[n] isn't present, that means the field wasn't checked, so you can ignore select[n].

Going further into your code and what you do with these fields once you've got them, you might find it even easier to pair them explicitly in the name: call the checkboxes "response[check][0]", "response[check][1]", etc., and the corresponding slsect boxes "response[email][0]", "response[email][1]", etc.. See what print_r() gives for that: you could end up avoiding that whole loop.

Thanks for the reply Weedpacket.
I think your solution will work.
I used your example by pairing them explicitly in the name.
This is what i get:

Array ( [response] => Array ( [email] => Array ( [0] => [1] => 3 ) [check] => Array ( [1] => 2 ) ) [sendstudentid] => Send Details )

and you are correct in saying that the select box value is displaying empty (as it should i guess).
My question is how do i now ignore that and get the [1] => 3 instead?
