List custom data in Wordpress

阅读更多关于 List custom data in Wordpress

I'm developing a plugin which has its own table. I need to display the data from the table in the Wordpress frontend (for example: category page). I don't need to JOIN this table with posts table, I just need to display the data from the table, with pagination. I need a separate page/custom template from my plugin directory (talking in a context of MVC frameworks — controller), on which this data should be displayed and paginated. Please give me an advice, what is the best practice to implement it? Thanks. If I understood your question then I think you need to add template_include hook to use

Need help with remove_action()

阅读更多关于 Need help with remove_action()

I'm trying to remove the unsightly embedded <STYLE> tag the built-in Recent Comments widget puts in my <HEAD> , but I can't seem to get the syntax right. It originally calls add_action( 'wp_head', array(&$this, 'recent_comments_style') ); to add it (in wp-includes/default-widgets.php, line 609 ), and I'm trying to undo it. I think it should be something like this: remove_action('wp_head', 'WP_Widget_Recent_Comments::recent_comments_style'); but with all the variations I've tried I still can't get it right. Does anyone know how to achieve this? Possibly Helpful: Function Reference: remove

Does a PHP library exist to work with PRC/.mobi files?

阅读更多关于 Does a PHP library exist to work with PRC/.mobi files?

问题 I'm writing a WordPress plugin to create an eBook from a selected category in most major eBook formats. I would like to support MobiPocket since that's the format used by the Kindle but I'm not sure how to go about it. From what I've read .mobi files are actually Palm Resource Databases (PRC) but I haven't been able to find a PHP class to work with these. I thought about using exec along with KindleGen but that would be undesirable as it would complicate initial setup. I've also thought about

问题 Is there a way to overwrite the default search function in wordpress? I have tried using the filters, but they only allow adding to the query... or possibly rewriting the whole query using posts_request. If I overwrite that though, no other querys will work. I have the following code function my_posts_request_filter($input) { if ( is_search() && isset($_GET['s'])) { global $wpdb; } return $input; } add_filter('posts_request','my_posts_request_filter'); I could override $input with my custom

Custom Page vs Plugin Slug

阅读更多关于 Custom Page vs Plugin Slug

I'm currently integrating information from a third party API into a wordpress site. What i need to do is create a "dynamic page" where it displays the details of a specific record from the API. Since there are 1000's of records i dont want to create a seperate page in wordpress for every record detail view. I've been looking around and it seems there are two main solutions (i've discarded the custom post type option as i dont think it fits my needs, but im open to re-evaluate). The first is to create a page in the wordpress pages admin, then setup a custom template for that page which calls

Modify Wordpress plugin function in functions.php

阅读更多关于 Modify Wordpress plugin function in functions.php

I need to change the value of a function from a Wordpress plugin that I'm using. If I do it in the original plugin file, it works perfectly, but I'd rather make it in functions.php to avoid problems on plugin update. I need to change this: public static function loop_shop_per_page() { return get_option( 'posts_per_page' ); } Into this: public static function loop_shop_per_page() { return '-1'; } How would I go to create a filter in functions.php to do just that? Without changing the core plugin code, I don't think you can achieve what you want. Well written plugins usually have apply_filters
