How Can I Solve Common Ajax Image Upload Problems?

Ajax Upload Image

Q&A

Q1. Ajax Fails to Upload Image

Your initial Ajax code appears to be missing crucial elements. To enable form submission, you must include success and error functions within your Ajax call.

Solution:

Modify your Ajax code as follows:

$(document).ready(function (e) {
    $('#imageUploadForm').on('submit',(function(e) {
        e.preventDefault();
        var formData = new FormData(this);

        $.ajax({
            type:'POST',
            url: $(this).attr('action'),
            data:formData,
            cache:false,
            contentType: false,
            processData: false,
            success:function(data){
                console.log("success");
                console.log(data);
            },
            error: function(data){
                console.log("error");
                console.log(data);
            }
        });
    }));
});

Q2. Trigger Upload on File Selection

To have the upload function trigger immediately when a file is selected, you need to modify the HTML input.

Solution:

Add the following to your HTML:

<input type="file">

This will submit the form and trigger the upload process once a file is selected.
