[RESOLVED] 3d array index not found?

[webnick]

Why doesn't this work?!?

$i = 3;
foreach($contact as $key => $val) {
if($val['name'] == 'tom'){
echo $val['name']; // Tom
echo $val['email'][$i] //DOESN"T PRINT [e-mail]
echo $val['email'][4]; //[e-mail]
...

Well, are you sure that $val['email'][3] is set and has the expected value of "[e-mail]"? You might want to do a print_r($val); to find out what the array's actual contents are.

It's not the value. I'm using a custom function to return either the email for question '2' the group emails for other questions. Echoing $fund[2]['email'][2] works but $i=2; echo $fund[2]['email'][$i] doesn't ??

The post looks like

$_POST[TrustFunds] => Array
        (
            [0] => AGC-International Union of Operating Engineers 07
            [1] => Alaska Carpenters Trust Funds 40
        )

And the source array:

$fund[] = array(
	'num' => '07',
	'name' => 'AGC-International Union of Operating Engineers',
	'email' => array( 
		0 => '',
		1  => '',
		2  => '[e-mail]',
		3  => '[e-mail]',
		4  => '[e-mail]',
		5  => ''
		)
	);
$fund[] = array(
	'num' => '40',
	'name' => 'Alaska Carpenters Trust Funds',
	'email' => array( 
		0 => '',
		1  => '',
		2  => '[e-mail]',
		3  => '[e-mail]',
		4  => '[e-mail]',
		5  => ''
		)
	);

The function is:

function findrecipient()
{
		global $question, $fund;
		if(isset($_POST['recipient']) && $_POST['recipient'] !== '') 
		{
				return $_POST['recipient'];
		}
		if(isset($_POST['ContactReason']) && !is_array($_POST['ContactReason']) && $_POST['ContactReason'] != '') 
		{ // return an email for the one question
				$qnum = substr(trim($_POST['ContactReason']), -2);
				foreach($question as $key => $val) 
				{
						if($qnum == $val['num'] && $val['email'] != '') {
								return $val['email']; 
						}
				}
		}
		if(isset($_POST['ContactReason']) && isset($_POST['TrustFunds']) && $_POST['TrustFunds'] != '') 
		{ // if question[email] skipped return the fund emails
				$holder = "";
				foreach($_POST['TrustFunds'] as $key => $val) 
				{ // form contains fund question, find the email for each fund
						$fnum = substr(trim($val), -2);
						foreach($fund as $key => $val) 
						{ // match funds array and an email
								if($fnum == $val['num']) && $val['email'][$qnum] != '') {

									$holder[] =  $val['email'][$qnum];
							}
					}
			}
			if(is_array($holder)) 
			{
					return implode(', ', $holder);
			}
	}
	// default return 
	return '[e-mail]';
}

Thanks for any help!
