Question

I have a session array [cart] of which contains user id numbers. I am trying to generate a list of email addresses from the contact table WHERE the contact id numbers in the session = the contact_id in the database.

Here is my code.

// Find cart members from the session array
foreach ($_SESSION['cart'] as $key=>$val) {
    $contactid = $val;

    // Query the database for cart members
    $cartresult = mysql_query("SELECT contact.email FROM contact WHERE contact.contact_id = '$contactid'");
    $emailresult = mysql_query($emailquery) or DIE (mysql_error());
    while ($r = mysql_fetch_array($emailresult)) { 
        $emailAry[] = $r['email']; 
    }
}

// Create comma separated list from email array
if (count($emailAry)) {
    $list = implode(", ", $emailAry);

    $list = str_replace(" ,", "", $list);

Apparently there is no value for $emailAry because the if statement is being neglected.

Any idea why this would be?

Answer 1

$emailquery from my perspective is undefined.

    $emailAry = array();

    // Find cart members from the session array
    foreach ($_SESSION['cart'] as $key=>$val) {
        $cartresult = mysql_query("SELECT email FROM contact WHERE contact_id = '$val'");
        while ($r = mysql_fetch_array($cartresult)) { 
            $emailAry[] = $r['email']; 
        }
    }

    // Create comma separated list from email array
    if (count($emailAry)) {
        $list = implode(",", $emailAry);

        // no need to replace ', ' with '', implode will do all the job creating a CSV :)
        //$list = str_replace(" ,", "", $list);
    }
