I can't add an image Web Service Prestashop - php

Question

When I try to add an image to a product I don't get any errors, but the image doesn't get added.
This is my code:
function addImage($idProduct)
{
$key = 'XXXXXXXXXXXXXXXXXXX';
$url = "http://192.168.1.81/api/images/products/".$idProduct;
$image_path = 'image2.jpg';
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_USERPWD, $key);
curl_setopt($ch, CURLOPT_POSTFIELDS, array('image' => '#'.$image_path.';type=image/jpg'));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$result = curl_exec($ch);
curl_close($ch);
echo '<h2>Image Added</h2>';
}
I also made a change on PSWebServiceLibrary.php, because Prestashop Web Service API keeps asking for authentication. This is the link where I got the code Prestashop Web Service API keeps asking for authentication .
This is the code I added:
$url .= '&ws_key=' . $this->key;
The problem is that the code to add an image was working before I made that change on PSWebServiceLibrary.php, and I don't know how to solve it.
I am using prestashop 1.6.1.5
Any help will be appreciated.
Greetings!

Answer 1

I think it's only a missing of "?" in your url.
If I follow your $url logic the result will be for product of ID 1234567 by example :
http://192.168.1.81/api/images/products/1234567&ws_key=ZOEJFD3429JD209AZJX0DJF20
So your server waits this url to hanlde ws_key as GET parameter :
http://192.168.1.81/api/images/products/1234567?ws_key=ZOEJFD3429JD209AZJX0DJF20
You need to add this "?" at the end of you URL like this :
$url = "http://192.168.1.81/api/images/products/".$idProduct."?";

For me works like this:
curl_setopt($ch, CURLOPT_POSTFIELDS, array('image' => curl_file_create($image_path)));
