Anyone know the how to pass long data through ajax. I need to pass the base 64 image string to php file. i didn’t pass

        // alert(images);
        $.ajax({
                method : 'POST',
                url  : 'saveImage.php',
                processData: true,
                data :  {

                   data : chart.getImageURI()
                },
                success: function (result) {
                    alert(result);
                    alert('image saved');

                 }
                
        });

What parameter is saveImage.php expecting the image string to belong to?

What is images after the following line?

var images = chart.getImageURI();

In the following, why do you call this same function again and assign it to the data property?

                data :  {
                   data : chart.getImageURI()
                },

Actually, i doing testing that parameter pass the value getting through the images variable. I try to pass that variable to data in ajax call.

//var images = chart.getImageURI();
        // alert(images);
        $.ajax({
                method : 'POST',
                url  : 'saveImage.php',
                processData: true,
                data :  {

                   data : chart.getImageURI()
                },
                success: function (result) {
                    alert(result);
                    alert('image saved');
                }                 
        });

chart.getImageURI() This function return a string which base 64 png image string which i want save on the server in png file for that i use ajax. So, i want post that string to my function so that i can process that string and save on to server.

I got an error somthing like URI is too long.
