How to use PHP to check form field for specific value?

The value '7' would need to be inserted or else the form field will be invalid; so invalid with all other numbers then 7.

if(empty($_POST['captcha']))
{
    $this->add_error("Did you solve the captcha?");
    $ret = false;
}

Works to check if any value -- but I need to specify, must be 7.

if(strlen($_POST['captcha']) =!7) // tried this but form completely died or disappeared
{
    $this->add_error("Did you solve the captcha?");
    $ret = false;
}

You have two problem:

=! should be !=

if(strlen($_POST['captcha']) != 7)

You also need to turn on error reporting.
