php foreach results - php

Question

foreach ($flr_array as $flr) {
if (!($flr = trim($flr)))
continue;
//list($flr, $keyword) = explode('|', $flr, 2);
$ip = '';
$err_msg = isValidFLR($flr, $ip);
if (!$err_msg) {
list($randlink, $lastid, $scr) = addLink($flr, $ip);
$flr = stripslashes($flr);
$url_array[$i]['number'] = $i + 1;
$url_array[$i]['flr'] = $flr;
$url_array[$i]['flr_substr'] = (strlen($flr) > 33) ? substr($flr, 0, 33) . '...' : $flr;
$url_array[$i]['randlink'] = $randlink;
$url_array[$i]['fullrand'] = $config['indexurl'] . $config['mod_rewrite_char'] . $randlink;
$url_array[$i]['scr'] = $scr;
$url_array[$i]['id'] = $lastid;
$url_array[$i]['flr_length'] = strlen($flr);
$url_array[$i++]['randlink_length'] = strlen($config['indexurl'] . $config['mod_rewrite_char'] . $randlink);
////
//$smarty->assign("flr_length", strlen($_REQUEST['flr']));
//$smarty->assign("randlink_length", strlen($config['indexurl'] . $config['mod_rewrite_char'] . $randlink));
////
} else {
js_alert($err_msg);
}
}
In function isValidFLR these is part of captcha check:
if ($config['captcha_check']) {
if (verifyCaptcha() == false) {
return 'Wrong code!';
}
}
Let's say in textarea i enter:
google.com
google.de
google.net
and enter wrong captcha code, so it gives me 3 messages of Wrong code!
It's happen i think because of foreach. Any ideas how to make in foreach display only one error message ?

Answer 1

Your question is hard to understand but I think you are right (in the foreach)....
if err_msg <> '' then you should put a break in your code to get out of the foreach (if that is what you want).

Answer 2

else {
js_alert($err_msg);
break; //this will break out of for loop
//or return false if it a function
}
