PHP validation checkbox

Question

I\'ve scoured the entire internet trying to find a solution to what I\'m missing here (or doing wrong). My form doesn\'t validate even when the check box is checked. Everything

The problem with your current validation is that you're using if-else wrongly and that you're using exit on every statement which will terminate your script prematurely.

You can do this instead:

For Terms:
    

//set an error counter to trigger the `exit`
$error_counter = 0;
if(trim($name) == '') {
    echo '
Attention! You must enter your name
';
    $error_counter++;
} 
if(trim($email) == '') {
    echo '
Attention! Please enter a valid email 
address.
';
    $error_counter++;
}
if(!isEmail($email)) {
    echo '
Attention! You have entered an invalid e- 
mail address, try again.
';
    $error_counter++;
} 
if(trim($subject) == '') {
    echo '
Attention! Please enter a subject.
';
    $error_counter++;
}
if(trim($comments) == '') {
    echo '
Attention! Please enter your message.
';
    $error_counter++;
}
if(empty($terms)) {
    echo '
Attention! Please agree to our terms of service.
';
    $error_counter++;
}
//if `$error_counter > 0 > 0` it will trigger the `exit()` to stop the script and display the errors.
if($error_counter > 0){
    exit();
}

There's a more beautiful approach to do this. Feel free to add suggestions for the OP.
