    Asked on August 18, 2020 at 10:54 AM

    I have a jotform and I am trying to submit the form using Curl, but it is not working!

    Here is the link for the jotform:


    I got the message the submission has been received, but the curl_file_create didn't work. Is there any way to fix this issue? 

    Here is the code:

    $linfox = $_POST['linfox'];

    $linfox = json_decode($linfox,false);

    for ($count = 0; $count <= count($linfox)-1; $count++) {

        foreach ($linfox[$count] as $key => $value) {

    if (stripslashes($key) == "q46_photoOf"){

      $data['temp_upload'][$key] = stripslashes($value); 

    //   $data[$key] = stripslashes($value);


      if (stripslashes($key) != "file"){

    $data[$key] = stripslashes($value); 


      $basename = pathinfo($value,PATHINFO_BASENAME);

      $url_remove = stripos($value,"files");

      $full_path = getcwd() . "/" . substr($value,$url_remove);

      $extension = "image/" . pathinfo($value,PATHINFO_EXTENSION);

    //$file = fopen ($value, 'w+');

          $file = curl_file_create($full_path,$extension,'IMG'.rand(1,10000000));

    //     $file = new CURLFile($full_path,$extension,'IMG'.rand(1,10000000));

      $data[$key] = $file;




     if (!function_exists('curl_init')){

        die('Sorry cURL is not installed!');


    $url = '';

    $ch = curl_init();

    curl_setopt($ch, CURLOPT_URL, $url);

    curl_setopt($ch, CURLOPT_POST, $count);

    curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-type: multipart/form-data;'));

    curl_setopt($ch, CURLOPT_POST, true);

    curl_setopt($ch, CURLOPT_SAFE_UPLOAD, true);

    curl_setopt($ch, CURLOPT_POSTFIELDS, $data);

    curl_setopt($ch, CURLOPT_HEADER, FALSE);

    curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);

    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, TRUE);

    $result = curl_exec($ch);

    Please note that you need to create an API key to post submission data. You can click here for additional information.

    I don't need to create API to post submission. This already works without API. I just need to know how I upload files using curl. Can you please help me with it?

    Can you please confirm, is other information successfully saved in the form? Are you unable to save only the image? You can also contact our API team using the following email:

    They will be able to provide your more relative information. 

    Thank you for your cooperation.

    Yes, the other information successfully saved in the form. I am not able to save only the image when I use curl. I posted all the information in the first question.

    We apologize for inconvenience. But please take note that the support system was meant for resolutions related to the Form Builder.

    Not all support members are programmers, or have knowledge related to curl programming.  You have higher chance of getting a resolution with our developers from the API team . So we suggest contacting them instead.
