我可以使用POST将AJAX与PHPMailer连接吗？

Question

I'm trying to make a contactform and I have js and php but no connection between them. Am I correct to use $_POST['Name'] when receiving a string as data from AJAX? Is there a way for me to find out what that string looks like?

EDIT: Ok, I've managed to find out that I constantly get NULL or empty array. I've also found out that it might be the header from jQuery and stringify that isn't a match with PHP. But that's too advanced for me to get. But I think a better question here is: How do I get a read out from PHP of the data I send?

EDIT2: var_dump($_POST); gives "array(0) { }". How do I get all raw data that's sent?

My javascript looks like this (found it online inorder to learn).

/*-------------
//lots of code to check validity of form
//-------------*/


    });
    if( ferror ) return false; 
    else var str = $(this).serialize();     
        $.ajax({
            type: "POST",
            url: "contactform.php",
            data: str,
            success: function(msg){
               // alert(msg);
                if(msg == 'OK') {
                    $("#sendmessage").addClass("show");         
                    $("#errormessage").removeClass("show"); 
                }
                else {
                    $("#sendmessage").removeClass("show");
                    $("#errormessage").addClass("show");
                    $('#errormessage').html(msg);
                }
            }
        });
    return false;
});
});

And my PHP looks like this.

<?php 
parse_str($_POST['str'], $var1);
var_dump ($var1);
$data = json_decode($_POST['data'], true);
var_dump($data);
?>

Answer 1

A data object needs to be sent with the ajax request so that you can access it in the php code. Which will generally look like-

data: {name: name, email: email}

In your code you are using str variable in the data object. So ensure that str represents the data object. I would say probably that is causing your problem.

Answer 2

Your PHP code needs an update.

Try this:

<?php
parse_str(file_get_contents("php://input"), $var1);
var_dump ($var1); //this will give you the array.
?>

You're close with your thoughts about jQuery and headers so I'll let you finish reading up and not go into detail.
