The best way would be to create a custom plugin for your site. Take a look at the plugin handbook to get started https://developer.wordpress.org/plugins/ In the plugin, you can just put the libraries in a folder, and include them in your main plugin code. Your plugin can then do one of these Register a shortcode … Read more
To keep posts updated, I am working with WordPress 4.4 and to enable/disable post revisions programmatically use: remove_action( ‘post_updated’, ‘wp_save_post_revision’ ); $post_id = wp_update_post( $arg ); add_action( ‘post_updated’, ‘wp_save_post_revision’ );
Like any other php object, you can add items to the $post object like so: $post->my_new_val_name=”my new value”; I don’t know exactly what you’re trying to do, but inside a function hooked to the_post, you can assign new values and return the object. function my_func($post) { $post->my_new_val_name=”my new value”; return $post; } add_action( ‘the_post’, ‘my_func’ … Read more
Setting page to be “posts page” changes its template hierarchy to follow home page rules. So your custom template is ignored and it looks for home.php or index.php, which might or might not be the reason it fails to render.
something like this maybe: function my_class_names($classes) { $useragent = $_SERVER[‘HTTP_USER_AGENT’]; if(strchr($useragent,’Safari’)) $classes[] = ‘Safari’; // etc.. return $classes; } add_filter(‘body_class’,’my_class_names’); Edit – as per Chip’s suggestion, here’s the function using the WordPress useragents checks: function my_class_names($classes) { global $is_lynx, $is_gecko, $is_IE, $is_opera, $is_NS4, $is_safari, $is_chrome, $is_iphone; if($is_lynx) $classes[] = ‘lynx’; elseif($is_gecko) $classes[] = ‘gecko’; elseif($is_winIE) … Read more
your function never defines a value for that field so when you check if its equal to 1 you never get true. try this: add_action( ‘show_user_profile’, ‘module_user_profile_fields’ ); add_action( ‘edit_user_profile’, ‘module_user_profile_fields’ ); function module_user_profile_fields( $user ) { ?> <h3>Module Options</h3> <table class=”form-table”> <tr> <th><label for=”module_activation”>Module Activation</label></th> <td> <input id=”module_activation” name=”module_activation” type=”checkbox” value=”1″ <?php if ( … Read more
You need to globalize it before you set the value, so in your header.php global $myBool; $myBool = false; and then in your page.php global $myBool; echo $myBool; just make sure you page.php includes the header.php file either directly or by calling get_header();
So, let’s say $query is your WP_Query object. I.e. $query = new WP_Query($some_query_args ); Then you can set up ‘the loop’, by $query->get_posts(); Then to check if there are actually any returned results: if ( $query->have_posts() ) : //Use a While loop to show the results else: //No results, let’s show a message instead. //This … Read more
As found here: http://codex.wordpress.org/Function_Reference/add_meta_box /** * Calls the class on the post edit screen */ function call_someClass() { return new someClass(); } if ( is_admin() ) add_action( ‘load-post.php’, ‘call_someClass’ ); /** * The Class */ class someClass { const LANG = ‘some_textdomain’; public function __construct() { add_action( ‘add_meta_boxes’, array( &$this, ‘add_some_meta_box’ ) ); } /** … Read more
Only under some circumstances. If the parent theme’s functions are wrapped in function_exists conditionals then you should be able to replace them. For example: // Parent if (!function_exists(‘p_wpse_95799’)) { function p_wpse_95799() { // } } If the child theme defines a function named p_wpse_95799 then the parent function will not be used. If this is … Read more
