Let’s give this a guess out of the blue: Check the encoding of your plugin file. It should be ASCII, also named US-ASCII or ascii-7bit. This ensures that your plugin is most compatible to wordpress installations out there. This information is probably useful for you to find out about the actual encoding of your plugins … Read more
It’s hard to say from your code. The exclude_tree parameter of wp_dropdown_categories() is pretty undocumented in codex. It’s making use of get_categories() which does not list it at all. If you don’t have children within that category, you can consider to use the exclude parameter instead / additional. Just give it a test if that … Read more
Contact plugin’s developer and ask him to fix?.. But I guess that is probably not an option if plugin is broken badly and remains that way. For a quick band-aid try this right after object is created, to handle case of constructor not setting up field properly: if( !isset( $paypal_ipn->paypal_post_vars ) ) $paypal_ipn->paypal_post_vars = array();
The $current_user global isn’t setup until right before the ‘init’ action is called. So any code using it shouldn’t be fired until that action or later. I would also suggest using the get_current_user_id() method instead of getting the global directly.
First, the setting you want is ‘upload_max_filesize’, not ‘upload_max_size’. Second, both of those settings are PHP_INI_PERDIR, which means they can only be set with php.ini, .htaccess, or httpd.conf. For more information see the PHP documentation on php.ini directives and their configuration. I would suggest using .htaccess, personally. You might look into writing the information directly … Read more
Not sure is that a rule or just something that happens to work that way, but most of function that take capability as argument also accept roles in same argument. If I am not mistaken passing lowest role you want to grant access (‘author’) should work for that role and upwards. Please test before use.
Hi @Scott B: Your example doesn’t work for me when I use if (is_home()) but does when I use if (is_front_page()). Is there any chance that is the problem? Other than that it seems to work fine on my WordPress v3.0.3 install. Do you have other plugins that might be disabling the output of wp_list_categories()? … Read more
wp_html_excerpt($category->description, 25). Or you can create your own function. I’m using this: /** * Filters content based on specific parameters, and appends a “read more” link if needed. * Based on the “Advanced Excerpt” plugin by Bas van Doren – http://sparepencil.com/code/advanced-excerpt/ * * @since 1.0 * * @param string $content What to filter, defaults to … Read more
For unlinking, try: function superDeactivation() { $myFile = “testFile.txt”; if(is_file(“$myFile”)) { unlink(“$myFile”); } } Or alternatively: function superDeactivation() { $myFile = “testFile.txt”; unset($myFile); unlink(“$myFile”); }
Here’s a simple solution. Append the ratings to the end of the post content: add_filter(‘the_content’, ‘add_ratings_to_content’, 4); // remove ratings from excerpts add_filter(‘get_the_excerpt’, create_function(”, ‘remove_filter(“the_content”, “add_ratings_to_content”, 6); return;’), 5); function add_ratings_to_content($content){ global $post; if(is_single()) $content .= the_ratings($post->ID); return $content; } Displays the current rating: function get_current_rating($post_id){ $votes = get_option(“votes_{$post_id}”); // handle your rating format here … Read more
