Multipel Checkboxes not working in form

roguewonder · August 15, 2014

I keep getting the warning "unable to send"

and yet I use everything in the for correctly.

Please help me out. I have spent hours looking for an answer.

It also posts the checkboxes I select at the bottom. I just want to be sent to the email, not necessarily echoed so I can view it.

Thanks

Have you checked your error log? It probably has an error message describing why mail() failed.

roguewonder · August 15, 2014

No error message in log file at all for that.

requinix · August 15, 2014

Check your mail settings in PHP, check your sendmail client's error logs... There is something out there that is wrong and I can't tell you what it is because I can't see your computer.

roguewonder · August 15, 2014

The mail settings are in the code I posted. So, you see nothing wrong in the code for the checkboxes?

There is nothing externally wrong as I can receive mail fine with another pph script that does not have multiple checkboxes.

Well of course it's not sending in the mail and echoing on the screen below, that's where the code for processing it is, at the bottom after all the other stuff that already processed. PHP reads the code from top to bottom, if things are in the right order, they won't process in the right order.

Put this block of code under your Validate User Comment check and remove it from the bottom of the page.

if(!empty($_POST['Activity'])) {
    $Activity = implode(', ', $_POST['Activity']);
    $message = $message."\r\n\r\nActivities Selected:".$Activity
}

Lastly, $Activity is not a mail() parameter, so take that out of there. You don't just list out the vars you want sent in the mail(). You need to build up the actual message to be sent and then use only the parameters that the mail() uses to send. You can read the php manual on how to use the mail()

Thanks Fastsol,

I didnt' hide my lack of php knowledge very well here. That's a very helpful source.
