I’m trying to upload product to my PHP upload system, that includes multiple variables, images among them.

I’m using ajax function to transfer string variables and newForm() (that related to images fetched from input[type="file"]). The main goal is to upload the image and strings in upload.php file using the data I’m fetching from ajax.

But there are troubles transfering the image value, once I send all the data together (including images) the system fails to transfer the data, because I’m forced to use processData: false, otherwise it fail to run the ajax function.

This attribute blocks the entire data transfer to my PHP file.

How can I over come processData: false influence, and transfer multiple strings and newForm() using AJAX to upload.php file?

AJAX:

      var proname = $('#proname').val();
      var prodescription = $('#prodescription').val();
      var content = $('#content').val();
      var price = $('#price').val();

      //Main image upload
      var file_main = $('#file').prop('files')[0];
      var main = new FormData();
      main.append('file', file_main);


      //Serval images upload
      var file_images = $('#files').prop('files')[0];
      var images = new FormData();
      images.append('files', file_images);




      //Checkboxes
      var tag = new Array();
      $("#tag input:checked").each(function() {
         tag.push($(this).val());
      });
      var color = new Array();
      $("#color input:checked").each(function() {
         color.push($(this).val());
      });


      //Ajax data transfer to upload.php
      $.ajax({
          type: 'POST',
          dataType: 'json',
          processData: false,
          url: 'upload.php',
          data: { proname: proname,
                  prodescription: prodescription,
                  content: content,
                  price: price,
                  tag: tag,
                  color: color,
                  file: main,
                  files: images
                }, // All the data as $_GET in php
          cache: false,
          success: function (result) {
            $('#success').html(result);
            console.log(result);
          }
        });

Note: If I remove Ajax data request and run the PHP code in the same page the code works.

Here, I would use only one instance of the FormData class.

var data = new FormData();
data.append('proname', proname);
data.append('prodescription', prodescription);
data.append('content', content);
data.append('price', price);
data.append('tag', tag);
data.append('color', color);
data.append('file', $("#file")[0].files[0]);

$.each($("#files")[0].files, function(i, file) {
    data.append('files[]', file);
});

Change/add in the ajax() call:

data: data, // change
contentType: false, // add

I use this following code to upload my form data including images/files. Hope it helps.

let yourForm = $('#yourForm');
let actoin = // your action page;
$.ajax({
        url: action,
        data:new FormData(yourForm[0]),
        async:false,
        type:'post',
        processData: false,
        contentType: false,
        success: function (data) {
           // your code here
        },
        error: function (data) {
            // your code here
        }
    });
