Uploading Both Data and Files in One Form Using Ajax

Uploading both data and files in one form using Ajax?

The problem I had was using the wrong jQuery identifier.

You can upload data and files with one form using ajax.

PHP + HTML

<?php

print_r($_POST);
print_r($_FILES);
?>

<form id="data" method="post" enctype="multipart/form-data">
    <input type="text" name="first" value="Bob" />
    <input type="text" name="middle" value="James" />
    <input type="text" name="last" value="Smith" />
    <input name="image" type="file" />
    <button>Submit</button>
</form>

jQuery + Ajax

$("form#data").submit(function(e) {
    e.preventDefault();    
    var formData = new FormData(this);

    $.ajax({
        url: window.location.pathname,
        type: 'POST',
        data: formData,
        success: function (data) {
            alert(data)
        },
        cache: false,
        contentType: false,
        processData: false
    });
});

Short Version

$("form#data").submit(function(e) {
    e.preventDefault();
    var formData = new FormData(this);    

    $.post($(this).attr("action"), formData, function(data) {
        alert(data);
    });
});

Sending file together with form data via ajax post

Can you try using FormData():

$("form#files").submit(function(){

    var formData = new FormData($(this)[0]);

    $.ajax({
        url: window.location.pathname,
        type: 'POST',
        data: formData,
        async: false,
        success: function (data) {
            alert(data)
        },
        cache: false,
        contentType: false,
        processData: false
    });

    return false;
});

The above is a sample code, but you may use it to modify it.

Uploading both data and files in one form using POST method, AJAX and jQuery (Error)

I have already undestood my mistake.

$_FILES will show me only file data, but if I want to see id_element I have to use $_POST.

The result is:

array(1) {
  ["id_element"]=>
  string(1) "1"
}

Ajax file upload more than one input and some data

You can use following javascript code to submit form.

var form = $("#formId")[0];
var data = new FormData(form);

$.ajax({
  type: "POST",
  url: "form-submit-url",
  data: data,
  processData: false,
  contentType: false,
  cache: false,
  success: function(data) {}
});

jQuery AJAX multiple files upload but send one file at a time to server using ajax

You can just use forEach method of FormData:

$('#submit-form').submit(function(e) {
  e.preventDefault();
  var formData = new FormData(this);
  var url = "upload-files.php";

  formData.forEach(function(entry) {
    if (entry instanceof File) {
      var fileForm = new FormData()
      fileForm.append('resume', entry)

      $.ajax({
        url: url,
        type: 'post',
        data: fileForm,
        success: function(response) {
          alert(response);
        },
        cache: false,
        contentType: false,
        processData: false
      })
    }
  })
})

form data upload multiple files through ajax together with text fields

Here is ajax, html and php global you can access. Let me know if it works for you.

// Updated part
jQuery.each(jQuery('#file')[0].files, function(i, file) {
    data.append('file-'+i, file);
});

// Full Ajax request
$(".update").click(function(e) {
    // Stops the form from reloading
    e.preventDefault();

        $.ajax({
        url: 'post_reply.php',
        type: 'POST',
        contentType:false,
        processData: false,
        data: function(){
            var data = new FormData();
            jQuery.each(jQuery('#file')[0].files, function(i, file) {
                data.append('file-'+i, file);
            });
            data.append('body' , $('#body').val());
            data.append('uid', $('#uid').val());
            return data;
        }(),
            success: function(result) {
            alert(result);
            },
        error: function(xhr, result, errorThrown){
            alert('Request failed.');
        }
        });
        $('#picture').val('');
$('#body').val('');
});

Updated HTML:

<form enctype="multipart/form-data" method="post">
  <input id="file" name="file[]" type="file"  multiple/>
  <input class="update" type="submit" />
</form>

Now, in PHP, you should be able to access your files:

// i.e.    
$_FILES['file-0']
