Send blob from javascript to PHP and save it as a file on server

We are looking for a PHP / JAVASCRIPT / AJAX / JQUERY developer with experience in files use. It's a simple job. We provide two downloadable scripts, without execution environment, to modify the code and we perform the tests. We have two files: 1) [login to view URL] This file contains an HTML / PHP form with text inputs and a file type input. We used it to upload a file by sending the data via $_POST to the second file. 2) [login to view URL] This file is a PHP script that obtains the $_POST and $_FILES data and saves the image to the server and the inputs to the database. We are integrating a javascript image editor, so the user can now edit the image before uploading it. It works correctly but this script returns a blob, not a file in an input as we had before. We can visualize the blob in the body, we have its url: // Create preview image and append to body element var image = new Image(); [login to view URL] = [login to view URL]([login to view URL]); We want, instead of previewing this blob, to send it together with the text inputs to the [login to view URL] file to continue the same data collection process. We are looking for someone able to *save the content of this blob in a hidden input file*, together with the rest of the values of the form, or to *send all the values of the form from javascript* and collect them in PHP in the second file [login to view URL], or able to *save the file in a temp folder in the server and save this url to the form so we can read the file from PHP*. Currently we obtain the file with $_FILES: if (isset($_FILES['uploadedFile']) && $_FILES['uploadedFile']['error'] === UPLOAD_ERR_OK && $_FILES['uploadedFile']['size'] > 1) { // get details of the uploaded file $fileTmpPath = $_FILES['uploadedFile']['tmp_name']; $fileName = $_FILES['uploadedFile']['name']; $fileSize = $_FILES['uploadedFile']['size']; $fileType = $_FILES['uploadedFile']['type']; $fileNameCmps = explode(".", $fileName); $fileExtension = strtolower(end($fileNameCmps)); // sanitize file-name $newFileName = md5(time() . $fileName) . '.' . $fileExtension; // check if file has one of the following extensions $allowedfileExtensions = array('jpg', 'png', 'jpeg'); (...) ImageJPEG($dst_img,'./i/laspichas/' . $user_nicename .'/' . date("m") . date("Y") . '/'. $newFileName,65); The image name is not important, must be random. The type will be image (jpg jpeg gif png). The size should be calculated. We are using DOKA to generate the blob. -> [login to view URL]
