I am building an assessment tool. The logic is:

  1. In each question, once I click 'Upload/View Files', it will pop up a modal;
  2. In the modal, there is a section you can select pic/document/video to upload. The code is as:Html code
  3. Once you click submit, it will trigger jquery as below:
        var formData = new FormData($(this)[0]);
            url: "ajax/upload-attachment.ajax.php",
            type: "POST",
            data: formData,
            async: false,
            cache: false,
            contentType: false, 
            processData: false,
            'success': function(data){
        }); //End of ajax

})//End of submit


  1. And the following is ajax php code:
require_once '../php-includes/';
global $db;

if($type=="file"){ $file=$_FILES["file"]; $fileName=$file["name"][0]; if(empty($fileName)){ echo "No File Selected"; return; } $fileType=$file["type"][0]; $fileData=$file["tmp_name"][0];

mysqli_query($db, "INSERT INTO files VALUES('$assess_id','$quest_ref','$fileName','$fileType','$fileData', NOW(), '$email', '')"); echo "Success";


  1. However, when I check database after uploading the file, it only upload the name like 'C:xampp mpphpFE6F.tmp' into the blob, apparently the $fileData is not correct. Could you please help me how i can do this?
