Error 401 uploading images using the web service with cURL and php 5.4.4

[qhe]

I have a problem when trying to upload an image with cURL in php 5.4.4: returns  HTTP/1.1 401 error
The php code is:
 

define("PS_SHOP_PATH", 'http://mydomain.com/');
define("PS_WS_AUTH_KEY", 'XXXXXXXXXXX' );
$img= _PS_TMP_IMG_DIR_  .$myfoto ;
$crlf = '<br>'; 

$curl = curl_init();
curl_setopt($curl,CURLOPT_HEADER, true);
curl_setopt($curl,CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl,CURLINFO_HEADER_OUT, true);
curl_setopt($curl, CURLOPT_URL, PS_SHOP_PATH . '/api/images/products/' .  $id_produc );
curl_setopt($curl, CURLOPT_POST, true);
curl_setopt($curl, CURLOPT_HTTPAUTH, 'CURLAUTH_BASIC');
curl_setopt($curl, CURLOPT_USERPWD, PS_WS_AUTH_KEY  );
curl_setopt($curl, CURLOPT_POSTFIELDS, array('image' => '@'.$img) );
if( ! $result = curl_exec($curl))
     { echo $crlf .'Error : '.$id_produc.' '.$img.' -> '. curl_error($curl). $crlf; }
else { echo $result. '<br>. Image added: ' . $img . $crlf  ; }

curl_close($curl);  

curl_exec ($curl) does not return false, but it does nothing.
The images are not added to ps_images table and the thumbnails do not regenerate

 

The result:

------------------------------------------------------------

I get the same error with different versions of prestashop (1.4.10.0, 1.5.6.1 and 1.6.0.5) in php 5.4.4.

However, at the same stores in php 5.2 works well

Do you know if there is any problem with prestashop webservice and php 5.4.4?

Thank you very much.

Quim

Hi,

 

I assume you already checked that $id_produc is there.

if( ! $result = curl_exec($curl))

Another possible source of trouble may be the line above. This kinda control is not considered as a good practice and may return unexpected results sometimes (what will be the case for "if", when curl_exec returns false? )

 

I hope this helps.

Thank you, Prestashopninja

How you would control the result of curl_exec?

[prestashopninja]

Normally, of course there's nothing wrong to do it the way you did and your code will naturally compile. 

On the other hand, to assign a value within a conditional really might cause some confusion especially when debugging the code as you both check a condition and assign a variable in the same statement.

To debug fast, I would assign the value first

$result = curl_exec($curl);

and then check the condition

if($result === FALSE)

or, as curl_exec will return only TRUE or FALSE,

if($result !== TRUE)

... and see if there's a problem with the value assignment, and then, in the conditional, in separate steps.

Once you verify everything works good with both of them, if you cannot live without assigning value in a conditional, you can change the code back to

if( ! $result = curl_exec($curl))

Thank you very much for your explanation Prestashopninja. I will change the code and all that I have like this.
