[RESOLVED] recaptcha

[tommyrulez]

I am calling a form from within another page. Do I really need recaptcha? I have a test for a hidden field that resets the form if it is filled out.

Thanks

there's no yes or no answer to this, there are circumstances in which captcha's are a bad idea.

NogDog, empty fields response.

Could I change your response to:

foreach($_POST as $key => $row)
{
$row = trim($row);
if($row == '')
{
$message .= "I\'m sorry, but ". $row. " is empty." \n";
header("Location: something.php?msg=$err");
exit();
}
}

f($row == '')
should be f($row == ''")

Thanks for the response, the reason I was asking because I keep get white something error and my public key shows in the form.

the $message line should be:

$message .= "I\'m sorry, but ". $row. " is empty \n";

however --

message would never be seen as you are redirected before its displayed; and if you did not use header you want $key not $row in the message as $row would be blank

Something like this or would I still need $key?

foreach($_POST as $key => $row)
{
$row = trim($row);
if($row == '')
{
$err .= urlencode("I\'m sorry, but ". $row. " is empty. \n");
header("Location: something.php?msg=$err");
exit();
}
}

You're checking if $row is empty, if it is you create the error message, therefore displaying the value of $row makes no sense, as it has to be empty to be displayed as part of the error message.

Perhaps you meant to use $key instead of $row in that message?
