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

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
For some reason, Woocommerce doesn’t seem to want you to do this. Not sure why, because requiring it to be done manually is a problem for scalability in a number of cases (not to mention, if you have attributes with a lot of possible values, the interface they provide loads really slowly). After digging a … Read more
