I am using wordpress 4.8, contactform7 4.8 and jquery file upload
and trying to add multiple file upload support in contact form 7.
now, my script is
( function( $ ) {
'use strict';
var url = window.location.hostname === 'blueimp.github.io' ?
'//jquery-file-upload.appspot.com/' : ajax_object.ajax_url;
$('.wpcf7-multifile').fileupload({
url: url,
dataType: 'json',
autoUpload: true,
acceptFileTypes: /(\.|\/)(gif|jpe?g|png)$/i,
maxFileSize: 99900000,
// Enable image resizing, except for Android and Opera,
// which actually support image resizing, but fail to
// send Blob objects via XHR requests:
disableImageResize: /Android(?!.*Chrome)|Opera/
.test(window.navigator.userAgent),
previewMaxWidth: 100,
previewMaxHeight: 100,
previewCrop: true
}).on('fileuploadadd', function (e, data) {
//console.log(data.files);
data.context = $('<div/>').appendTo('#files');
data.formData = {action : 'do_file_upload'};
$.each(data.files, function (index, file) {
var node = $('<p/>')
.append($('<span/>').text(file.name));
if (!index) {
node
.append('<br>')
}
node.appendTo(data.context);
});
}).on('fileuploadprocessalways', function (e, data) {
var index = data.index,
file = data.files[index],
node = $(data.context.children()[index]);
if (file.preview) {
node
.prepend('<br>')
.prepend(file.preview);
}
if (file.error) {
node
.append('<br>')
.append($('<span class="text-danger"/>').text(file.error));
}
}).on('fileuploadprogressall', function (e, data) {
var progress = parseInt(data.loaded / data.total * 100, 10);
$('#progress .progress-bar').css(
'width',
progress + '%'
);
}).on('fileuploaddone', function (e, data) {
console.log(data.result.files);
$.each(data.result.files, function (index, file) {
if (file.url) {
var link = $('<a>')
.attr('target', '_blank')
.prop('href', file.url);
$(data.context.children()[index])
.wrap(link);
} else if (file.error) {
var error = $('<span class="text-danger"/>').text(file.error);
$(data.context.children()[index])
.append('<br>')
.append(error);
}
});
}).on('fileuploadfail', function (e, data) {
//console.log("upload failed");
console.log(e);
$.each(data.files, function (index) {
var error = $('<span class="text-danger"/>').text('File upload failed.');
$(data.context.children()[index])
.append('<br>')
.append(error);
});
}).prop('disabled', !$.support.fileInput)
.parent().addClass($.support.fileInput ? undefined : 'disabled');
} )( jQuery );
and this is my UploadHandler.php.
my html is
<p><label> Multi File<br>
<span class="wpcf7-form-control-wrap multifile-966"><input type="file" name="multifile-966[]" size="40" class="wpcf7-form-control wpcf7-multifile multi-file" id="multi-file" multiple="multiple" aria-invalid="false"></span></label></p>
server site ajax callback is
add_action('wp_ajax_do_file_upload', 'do_file_upload');
add_action('wp_ajax_nopriv_do_file_upload', 'do_file_upload');
if ( ! function_exists('do_file_upload') ){
function do_file_upload(){
$options = [
'param_name' => key($_FILES)
];
require('server/php/UploadHandler.php');
$upload_handler = new UploadHandler($options);
}
}
file upload getting failed.

I converted these two response to array in UploadHandler.php file post method and both are 100% same !!only difference is a 0 at the end of the json response, may be that is giving some idea, but now I have no idea why not it is showing file upload failed, the file are getting uploaded but temporarily when I am refreshing the page, they disappeared .
also updated UploadHandler.php .
Update
changed
return $this->generate_response($response, $print_response);
to
$print_response = false;
wp_send_json($this->generate_response($response, $print_response));
makes the extra 0 disappeared, but still the upload is temporary, but expected behavior is upload to be permanent.
update2
in UploadHandler.php for
move_uploaded_file($uploaded_file, $file_path);
I am getting true. echo var_dump(move_uploaded_file($uploaded_file, $file_path)); is true.
changing UploadHandler.php
these two lines
'upload_dir' => dirname(dirname($this->get_server_var('SCRIPT_FILENAME'))) . '/wp-content/uploads/wpcf7_uploads/',
'upload_url' => $wp_content_url . 'wpcf7_uploads/',
to any other folder beside wpcf7_uploads makes it work.
I changed it to
'upload_dir' => dirname(dirname($this->get_server_var('SCRIPT_FILENAME'))) . '/wp-content/uploads/2017/wpcf7_uploads/',
'upload_url' => $wp_content_url . '2017/wpcf7_uploads/',
