curl_exec returns false when trying to upload image to Prestashop using PHP

Question

I'm trying to add photo for existing product in my Prestashop 1.7.5.1 shop. I found example code on: https://devdocs.prestashop.com/1.7/development/webservice/tutorials/change_product_image/ and changed it so it has my shop addres and my key. I also changed line

$args['image'] = new CurlFile($image_path, $image_mime); to

$args['image'] = new CurlFile($image_path, $image_mime, '1.jpg'); beacause Visual Studio Code highlighted that CurlFile also needs third argument - postname. Here is my code:

<?php
    define('DEBUG', true);
    $url = 'http://test.my_shop.com';
    $key  = 'MY_AUTH_KEY';

    $psProductId = '2364';
    $urlImage = $url.'/api/images/products/'.$psProductId.'/';

    $image_path = '/img/1.jpg';
    $image_mime = 'image/jpg';
    $args['image'] = new CurlFile($image_path, $image_mime, '1.jpg');

    $ch = curl_init();
    curl_setopt($ch, CURLOPT_HEADER, 1);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLINFO_HEADER_OUT, 1);
    curl_setopt($ch, CURLOPT_URL, $urlImage);
    curl_setopt($ch, CURLOPT_POST, 1);
    curl_setopt($ch, CURLOPT_USERPWD, $key.':');
    curl_setopt($ch, CURLOPT_POSTFIELDS, $args);

    print("<pre>");
    echo '<br>curl_exec <br>';
    $data_exec = curl_exec($ch);
    var_dump($data_exec);
    echo '<br>curl_getinfo <br>';
    var_dump(curl_getinfo($ch));
    echo '<br>curl_errno <br>';
    var_dump(curl_error($ch));
    echo '<br>curl_error <br>';
    var_dump(curl_error($ch));
    print("</pre>");

    curl_close($ch);
?>

I placed all those var_dumps because I wanted to gather as much info as possible. When I run this code in my browser using XAMPP i get following output:


curl_exec

}

curl_errno

curl_error 
string(0) ""

I have no idea what I'm doing wrong. I don't know why code posted on documentation page is not working dor me. If someone has any suggestion please post them, thanks.

You're printing `curl_error()` when you should be printing `curl_errno()`. — Barmar, Sep 17 '19 at 16:16
@Barmar thank you for your comment. I changed my code and thanks to that I was able to correct my code. I post it in my answer. — piterz, Sep 17 '19 at 22:17

I corrected first var_dump(curl_error($ch)); in my code and replaced it with var_dump(curl_errno($ch));. After i ran the code I got error no. 26

curl_errno
int(26)

I looked it up and found this answer: curl: (26) couldn't open file. I changed relative path to full path and now my code is fully working, photos are uploaded correctly. Here is my corrected code:

<?php
    define('DEBUG', true);
    $url = 'http://test.my_shop.com';
    $key  = 'MY_AUTH_KEY';

    $psProductId = '2364';
    $urlImage = $url.'/api/images/products/'.$psProductId.'/';

    $image_path = 'C:/xampp/htdocs/my_folder/img/1.jpg';
    $image_mime = 'image/jpg';
    $args['image'] = new CurlFile($image_path, $image_mime, '1.jpg');

    $ch = curl_init();
    curl_setopt($ch, CURLOPT_HEADER, 1);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLINFO_HEADER_OUT, 1);
    curl_setopt($ch, CURLOPT_URL, $urlImage);
    curl_setopt($ch, CURLOPT_POST, 1);
    curl_setopt($ch, CURLOPT_USERPWD, $key.':');
    curl_setopt($ch, CURLOPT_POSTFIELDS, $args);

    print("<pre>");
    echo '<br>curl_exec <br>';
    $data_exec = curl_exec($ch);
    var_dump($data_exec);
    echo '<br>curl_getinfo <br>';
    var_dump(curl_getinfo($ch));
    echo '<br>curl_errno <br>';
    var_dump(curl_errno($ch));
    echo '<br>curl_error <br>';
    var_dump(curl_error($ch));
    print("</pre>");

    curl_close($ch);
?>

It's too bad that `curl_error()` doesn't show that. I guess it only shows errors that come from the server, not local errors. — Barmar, Sep 18 '19 at 15:19
