function returns no value
Hello,
with the following call I try to print a string out of DB echo $allg->translate($db, $lang, 14, "auth/authCallback", 4); function translate () should do a DB querry and returns the requested string. Although the querry yields a positive result, the function returns no value. Here is the function: function translate ($db, $lang, $MaiKey, $page, $pid) { $statement = "SELECT fa FROM language WHERE MaiKey='$MaiKey' AND page='$page' AND pid='$pid'"; $result = $db->Execute($statement); if ($result=== false) die(); return $result->fields[0]; } Could anybody see what is going wrong here? I appreciate any hint. Ali

Re: [PHP] function returns no value
Can't really know without the rest of the code.
Check if the function really returns and not Dying (Add some messege like: die("help me I'm dying"); ). Also use print_r or something like to see what's inside the fields array. it is possible that it's an associative array and you are using the wrong index (0) Liran ----- Original Message ----- From: "Ali Reza Sajedi" <arsajedi@khanehjou.com> To: <php-general@lists.php.net> Sent: Sunday, April 20, 2008 11:51 PM Subject: [php] function returns no value > Hello, > > with the following call I try to print a string out of DB > > echo $allg->translate($db, $lang, 14, "auth/authCallback", 4); > > function translate () should do a DB querry and returns the requested > string.

Re: [PHP] function returns no value
I added var_dump($result); to the function.
As part of the output I get the following: ["fields"]=> array(1) { ["fa"]=> string(22) "ورود به سایت"} which is the string which should be returned and printed. The result is there, however, it couldn't be printed. Any ideas?

Re: [PHP] function returns no value
using $result->fields["fa"] did solve the problem.
