Сохранение нескольких просмотренных файлов в папку [дубликат]

Используя этот исходный код, вы можете загружать несколько файлов, например google, один за другим через ajax. Также вы можете увидеть прогресс загрузки

HTML

 <input type="file" id="multiupload" name="uploadFiledd[]" multiple >
 <button type="button" id="upcvr" class="btn btn-primary">Start Upload</button>
 <div id="uploadsts"></div>

Javascript

<script>

function uploadajax(ttl,cl){

var fileList = $('#multiupload').prop("files");
$('#prog'+cl).removeClass('loading-prep').addClass('upload-image');

var form_data =  "";

form_data = new FormData();
form_data.append("upload_image", fileList[cl]);


var request = $.ajax({
          url: "upload.php",
          cache: false,
          contentType: false,
          processData: false,
          async: true,
          data: form_data,
          type: 'POST', 
          xhr: function() {  
      var xhr = $.ajaxSettings.xhr();
      if(xhr.upload){ 
        xhr.upload.addEventListener('progress', function(event){
                        var percent = 0;
                        if (event.lengthComputable) {
                            percent = Math.ceil(event.loaded / event.total * 100);
                        }
                        $('#prog'+cl).text(percent+'%')

                    }, false);
       }
      return xhr;
     }    
      })
      .success(function(res,status) {

        if(status == 'success'){

            percent = 0;
            $('#prog'+cl).text('');            

                $('#prog'+cl).text('--Success: ');

            if(cl < ttl){
                uploadajax(ttl,cl+1);
            }else{
               alert('Done ');

            }     

            }

      })
      .fail(function(res) {
      alert('Failed');
      });

}



$('#upcvr').click(function(){

var fileList = $('#multiupload').prop("files");
$('#uploadsts').html('');
var i
for ( i = 0; i < fileList.length; i++) {
$('#uploadsts').append('<p class="upload-page">'+fileList[i].name+'<span class="loading-prep" id="prog'+i+'"></span></p>');
if(i == fileList.length-1){
    uploadajax(fileList.length-1,0);
}
}

});

</script>

PHP

upload.php
    move_uploaded_file($_FILES["upload_image"]["tmp_name"],$_FILES["upload_image"]["name"]);

HTML

<form enctype="multipart/form-data" action="upload.php" method="post">
    <input name="file[]" type="file" />
    <button class="add_more">Add More Files</button>
    <input type="button" value="Upload File" id="upload"/>
</form>

Javascript

 $(document).ready(function(){
    $('.add_more').click(function(e){
        e.preventDefault();
        $(this).before("<input name='file[]' type='file'/>");
    });
});

для загрузки ajax

$('#upload').click(function() {
    var filedata = document.getElementsByName("file"),
            formdata = false;
    if (window.FormData) {
        formdata = new FormData();
    }
    var i = 0, len = filedata.files.length, img, reader, file;

    for (; i < len; i++) {
        file = filedata.files[i];

        if (window.FileReader) {
            reader = new FileReader();
            reader.onloadend = function(e) {
                showUploadedItem(e.target.result, file.fileName);
            };
            reader.readAsDataURL(file);
        }
        if (formdata) {
            formdata.append("file", file);
        }
    }
    if (formdata) {
        $.ajax({
            url: "/path to upload/",
            type: "POST",
            data: formdata,
            processData: false,
            contentType: false,
            success: function(res) {

            },       
            error: function(res) {

             }       
             });
            }
        });

PHP

for($i=0; $i<count($_FILES['file']['name']); $i++){
    $target_path = "uploads/";
    $ext = explode('.', basename( $_FILES['file']['name'][$i]));
    $target_path = $target_path . md5(uniqid()) . "." . $ext[count($ext)-1]; 

    if(move_uploaded_file($_FILES['file']['tmp_name'][$i], $target_path)) {
        echo "The file has been uploaded successfully <br />";
    } else{
        echo "There was an error uploading the file, please try again! <br />";
    }
}

/** 
    Edit: $target_path variable need to be reinitialized and should 
    be inside for loop to avoid appending previous file name to new one. 
*/

Пожалуйста используйте сценарий выше скрипта для загрузки ajax. Он будет работать

Мое решение

• Предполагая, что форма id = "my_form_id"
• Определяет метод формы и форму action из HTML

Код jQuery

$('#my_form_id').on('submit', function(e) {
    e.preventDefault();
    var formData = new FormData($(this)[0]);
    var msg_error = 'An error has occured. Please try again later.';
    var msg_timeout = 'The server is not responding';
    var message = '';
    var form = $('#my_form_id');
    $.ajax({
        data: formData,
        async: false,
        cache: false,
        processData: false,
        contentType: false,
        url: form.attr('action'),
        type: form.attr('method'),
        error: function(xhr, status, error) {
            if (status==="timeout") {
                alert(msg_timeout);
            } else {
                alert(msg_error);
            }
        },
        success: function(response) {
            alert(response);
        },
        timeout: 7000
    });
});
