Updating Profile Image

[Samurai Legend]

Hello all, I have an issue which I can not identify the issue why it occurs. Whenever, someone uses an Photobucket link to update their image it gives an error however, using an alternative image host it gives no errors?

Error Message -

 

Samurai Assault - Critical Error

 

A critical error has occurred, and page execution has stopped. Below are the details:

try going to the link... it's not an image. http://s1104.photobucket.com/user/Jordan_Pollard/media/YWN.png

[Magictallguy]

Heh, that's my isImage function..

[Samurai Legend]

[uSER=53425]Magictallguy[/uSER] - Yes indeed, it is your function. You was helping me out remember :P

But yeah I can't seem to see the issue why it don't work with Photobucket links?

[Magictallguy]

Exactly what Hax-guy said; that URL isn't an image

Edit: Just tested with a direct URL given by PhotoBucket itself (http://i871.photobucket.com/albums/ab277/ANNNNNNNNA_bucket/Animated%20Gif/Psychedelic%20Animated%20Gifs/AnimatedAura.gif), seems to work fine for me

[Samurai Legend]

Aha, understood. How would I make it not show the error?

[Magictallguy]

Set DEBUG to false in the error handler

[Samurai Legend]

I need that switched on, can I not use an IF statement?

[Magictallguy]

I suppose you could do this:

$fp = @fopen($url, 'rb', false, $ctx);  

[Samurai Legend]

[uSER=53425]Magictallguy[/uSER] - Thank you MTG however, I am still receiving an error:

$fp = @fopen($url, 'rb', false, $ctx) or exit('Couldn\'t load URL');

?

[Samurai Legend]

[uSER=53425]Magictallguy[/uSER] I still get the error

[Magictallguy]

My tests show no error with my code..

[TheMasterGeneral]

The issue appears to only happen when the URL itself does not return a "Success" header. (404, 403, etc.)

When I input "http://somerandomwebsite.com/fake/url/image/watever.png" it failed on the fopen.

"PHP Warning: fopen(http://somerandomwebsite.com/fake/url/image/watever.png): failed to open stream: HTTP request failed! HTTP/1.1 403 Forbidden (2)

 

Perhaps test for the returned header/response?

[Magictallguy]

'twas the fopen() before hitting the headers.

Code updated and repiared

 

function isImage($url = null) {
   $url = filter_var($url, FILTER_VALIDATE_URL) ? filter_var($url, FILTER_SANITIZE_URL) : null;
   if(empty($url))
       return false;
   $params = ['http' => ['method' => 'HEAD']];
   $ctx = stream_context_create($params);
   $fp = @fopen($url, 'rb', false, $ctx) or false;
   if(!$fp)
       return false;  // Problem with url
   $meta = stream_get_meta_data($fp);
   if ($meta === false) {
       fclose($fp);
       return false;  // Problem reading data from url
   }
   $wrapper_data = $meta['wrapper_data'];
   if(is_array($wrapper_data))
       foreach(array_keys($wrapper_data) as $hh)
           if (substr($wrapper_data[$hh], 0, 19) == "Content-Type: image") {
               fclose($fp);
               return true;
           }
   fclose($fp);
   return false;
}

[TheMasterGeneral]

Weirdly enough, it works in a single file (test.php)

However, in a live (in-dev) application, it does not. I find this quite strange.

Code, if you need it. That's exactly how it is handled right now in my application.

function isImage($url = null) { 
   $url = filter_var($url, FILTER_VALIDATE_URL) ? filter_var($url, FILTER_SANITIZE_URL) : null; 
   if(empty($url)) 
       return false; 
   $params = ['http' => ['method' => 'HEAD']]; 
   $ctx = stream_context_create($params); 
   $fp = @fopen($url, 'rb', false, $ctx) or false; 
   if(!$fp) 
       return false;  // Problem with url 
   $meta = stream_get_meta_data($fp); 
   if ($meta === false) { 
       fclose($fp); 
       return false;  // Problem reading data from url 
   } 
   $wrapper_data = $meta['wrapper_data']; 
   if(is_array($wrapper_data)) 
       foreach(array_keys($wrapper_data) as $hh) 
           if (substr($wrapper_data[$hh], 0, 19) == "Content-Type: image") { 
               fclose($fp); 
               return true; 
           } 
   fclose($fp); 
   return false; 
}

URL given: "asdf"

Code:

<?php
require_once __DIR__ . '/includes/globals.php';
function isImage($url = null) {
   $url = filter_var($url, FILTER_VALIDATE_URL) ? filter_var($url, FILTER_SANITIZE_URL) : null;
   if(empty($url))
       return false;
   $params = ['http' => ['method' => 'HEAD']];
   $ctx = stream_context_create($params);
   $fp = @fopen($url, 'rb', false, $ctx) or false;
   if(!$fp)
       return false;  // Problem with url
   $meta = stream_get_meta_data($fp);
   if ($meta === false) {
       fclose($fp);
       return false;  // Problem reading data from url
   }
   $wrapper_data = $meta['wrapper_data'];
   if(is_array($wrapper_data))
       foreach(array_keys($wrapper_data) as $hh)
           if (substr($wrapper_data[$hh], 0, 19) == "Content-Type: image") {
               fclose($fp);
               return true;
           }
   fclose($fp);
   return false;
}
$images = [
   null,
   '',
   'http://google.com',
   'http://somerandomwebsite.com/fake/url/image/watever.png',
   'https://image.freepik.com/free-icon/teddy-bear_318-104767.jpg'
];
foreach($images as $image)
   echo (isImage($image) ? 'Yup.. <em>'.$image.'</em> is an image' : 'Nah, no image here - <em>'.($image ? $image : 'No URL given').'</em>!').'<br />';

 

First test (single file):

Usage of code (minor update to fit my system):

Second test (within [settings|preferences].php):

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

Url given: https://s-media-cache-ak0.pinimg.com...1983a96c11.jpg

Exact same code

Output:

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

If it's failing in your code, your server's settings (php.ini) may not allow remote file opening via fopen()
