PHP json响应不起作用

Question

I am doing an ajax update. I just want a response of success or failure so I know how to handle some things in the front end. Problem is it isn't working. Brand new to all of this.

$('.delete-template-popup .confirm').on('click', function() {
    var templateName = $('.loaded-template-name').html();

    var templateArray = {};

    templateArray.templateName = templateName;

    var JSONObject = [templateArray];
    var templateJson = JSON.stringify(JSONObject);

    $.ajax({
        url: 'http://localhost/ds-layouts/public/delete-template.php',
        type: 'post',
        data: {"templatePHP" : templateJson},
        success: function(data) {
            console.log(data)
            if (data.status == "success") {
                console.log(1)
            }
            // if (data.status == "success") {
            //  closePopup($('.delete-template-popup'));
            //  window.location.replace("http:////localhost/ds-layouts/public/manage-layouts.php");
            // } else {
            //  $('.delete-template-popup .error').show().html('An error occurred processing your request.  Please try again.  If this error persists contact blah.');
            // }                        
        }
    });
});

and the php

if ($flag) {
        //mysqli_commit($connection);
        if ($debug) {
            echo "pass";
            echo "
";
        }
        //$_SESSION["message"] = "Template delete was successful.";
        //header('Content-Type: application/json');
        header('Content-Type: application/json; charset=UTF8');
        echo json_encode(array('status' => 'success'));
    } else {
        if ($debug) {
            echo "fail";
            echo "
";
        }
        //mysqli_rollback($connection);
        // header('Content-Type: application/json');
        // echo json_encode(array('status' => 'failure'));
    }

So the deal is I am getting into the if block of the php statment fine. If I have the header part of the block I get all of my echo statements passed properly and I can read them in Chromes developer console. The moment I uncomment the header statement nothing works. This is for either one of $flag cases true or false.

I have this same type of script in another area and it works absolutely fine. Don't mind the comments. I was just commenting things out as a way to figure out where things were breaking. That is how I determened the header was causing it.

Maybe adding the dataType: "json", to your AJAX request object will help?
