Cannot send form with checkboxes PHP - php

Question

I want to send a form that have checkboxes in it, it was working fine but I do not what I did that now I received an error everytime I send it. I think the problem has to do with the checkboxes because I recall that I had problems with them in the past. I am working with a single file in PHP.
This is the code for the form:
<div class="contactFrm">
<?php if(!empty($statusMsg)){ ?>
<p class="statusMsg <?php echo !empty($msgClass)?$msgClass:''; ?>"><?php echo $statusMsg; ?></p>
<?php } ?>
<form action="" method="post">

Any help pointing out my error would be appreciated.

Answer 1

If you are getting this message:
Your contact request submission failed, please try again.
Then this portion of the code is throwing that message:
// Send email
if(mail($toEmail,$emailSubject,$htmlContent,$headers)){
$statusMsg = 'Your contact request has been submitted successfully !';
$msgClass = 'succdiv';
}else{
$statusMsg = 'Your contact request submission failed, please try again.';
$msgClass = 'errordiv';
}
Which means that the mail() function is returning false. Make sure that the mail() function works by passing in parameters you know are valid, such as those from the other contact form you say is working. Also, maybe try removing the $headers and see if that helps, since that part is optional.

Answer 2

i have checked your code and every time it's working but you don't handle it if checked box not selected that time occurring error just handle it,
may be use miss it checked boxed selection .
