First, Here is the full error:
PHP Fatal error: Call to undefined function download_url() in /path/to/wordpress/wp-admin/includes/media.php on line 562 I have also posted the related functions at the bottom of my question.
I am modifying a script for my company's website which allows us to automate the retrieval and uploading of content from our content provider. Due to the way they organize their XML, I need to upload the images related to the articles separately from the main body of the articles. I tried using media_sideload_image() to do this, but I recieved the error:
The function (media_sideload_image()) which calls download_url and results in the error:
PHP Fatal error: Call to undefined function download_url() in /path/to/wordpress/wp-admin/includes/media.php on line 562 As can be seen, I successfully included media.php - and the rest of my script has already been implemented on to the site, and I have not run into any other issues with accessing Wordpress files. The error would appear to be with media.php itself - which I find unusual.
Any ideas on how I can resolve this problem? Alternatively, if you know of another function I can use to do this, that would also be appreciated.
By all means, if you require any more details on the issue just ask.

//Upload the image if it exists, and return the post_id function upload_image($post_id, $image_url) { require_once('wp-admin/includes/media.php'); $image_url = 'http://admin.gkbusiness.com/gkbusiness/files/2011/04/LOGOGKMBUS1.jpg'; media_sideload_image($image_url, $post_id); return $post_id; }
