Question

I have a jQuery variable. It’s a text string. I want to create a .txt file on the server, then write that string to the text file.

How do I trigger this without reloading the page? I know PHP will have to get involved somewhere…

My attempts to do this with $.ajax(); haven’t worked.

You could pass this variable to a php script:

var data = 'foo bar';
$.post('/foo.php', { data: data }, function(result) {
    // success
    alert('the data was successfully sent to the server');
});

or if you prefer using $.ajax:

var data = 'foo bar';
$.ajax({
    url: '/foo.php',
    type: 'POST',
    data: { data: data },
    success: function(result) {
        alert('the data was successfully sent to the server');
    }
});

and then inside your foo.php script read the data from $_POST["data"] and save the contents to some file on the server.
