How can I properly test PHP scripts that have been POSTed to using AJAX?

I'm struggling to work out how to test my code.

I have a script in PHP which takes values from a string and puts them together into a message to be mailed.

The form is submitted using AJAX as follows:

$.ajax({
    type: "POST",
    url: "actions/sendForm.php",
    data: dataString,
    success: console.log('Success!')
});

The data is supposed to be passed to the PHP script. The var dataString looks like this:

var dataString = 'name='+name+'&company='+company+'&email='+email+'&phone='+phone+'&message='+message+'&signup='+signUp;

I am then trying to access these vars as such:

parse_str($dataString);

echo $name;
echo $company;
echo $email;
echo $phone;
echo $message;
echo $signUp;

My issue is that something is not happening, and I cannot test my PHP script any more because I am submitting via AJAX, so I never actually hit the script with the correct data.

How can I test a script working/echo variables etc when the form is submitted via AJAX?

Best How To :

As the method is POST, just echo the $_POST value:

print_r($_POST);

Or, like in your example, but instead of parse_str use extract:

extract($_POST);

echo $name;
echo $company;
echo $email;
echo $phone;
echo $message;
echo $signUp;

And in your ajax function change success to:

success: function( msg ) {
    console.log(msg);
}

to see what was printed in PHP script.
