Question

I’m sending an ajax call to my PHP script as follows:

function load(){
    var request = {};
    request['action'] = 'load';
    request['file'] = 'lorem_ipsum.txt';
    $.ajax({
        type: 'POST',
        url: cgi_file,
        data: JSON.stringify(request),
        processData: false,
        dataType: 'html',
        contentType: 'application/html',
        success:function(response){
            console.log("received " + response);
        }
    });
}

and my PHP script is as follows:

$content_dir = '/static/content/';

$action = $_POST['action'];

switch ($action){
    case 'load':
        $file = $_POST['filename'];
        echo file_get_contents($content_dir . $file);
        exit();
}

The PHP is responding with the following failure:

Notice: Undefined index: action in /var/www/river/api.php on line 5

What’s the issue here?

Try ditch processData: false and contentType: 'application/html' and it should work

$.ajax({
    type: 'POST',
    url: cgi_file,
    data: request,
    dataType: 'html',
    success:function(response){
        console.log("received " + response);
    }
});
