I figured it out!! My final code looks like: <?php $images = intval($wpdb->get_var(“SELECT COUNT(*) FROM $wpdb->nggpictures”)); $ngg_options = nggGallery::get_option(“ngg_options”); $maxElement = $ngg_options[“galImages”]; if ($images > $maxElement) { echo “duck”; } ?> Basically the code checks see if the number of images IS larger than the number of images displayed per page…if it is larger I … Read more
You might want to consider using the WordPress function body_class() <body <?php body_class($class); ?>> Then you could use the body class as your current page reference. This function is for example used by the Twenty-Twelve theme. For a single post it will become <body class=”single single-post …”> and for the home page: <body class=”home blog … Read more
Conditional tags mostly derive from and rely on main query. is_page() function calls $wp_query->is_page() method which checks $wp_query->is_page property (set during load) and some more stuff if you asked to check for specific page. So the likely reason for conditional tag not to produce expected return is issue with global $wp_query, for example it getting … Read more
The dynamic sidebar code you are using uses the page title of the topmost page to name the sidebar. get_the_title finds the title of the page you are on, not the topmost page title. You need a function that tells you the title of the topmost page in a page hierarchy. /** * Get the … Read more
is_tag checks whether the page being displayed is the tag archive page for the named tag. It does not check whether the post in a Loop has that tag, which is what you ask: “…to show if the post has tag premium…”. For that you need has_tag if has_tag( ‘premium’ ){ ?> <a href=”https://wordpress.stackexchange.com/questions/125158/<?php the_permalink(); … Read more
If your certain sidebar widget area is page-specific then I think you need to load classes only to those pages. If so, use is_page() with it: if( is_page(‘that-page’) && is_active_sidebar(‘your-sidebar’) ) { $class=”your-class “; } If it’s true for all the inner pages other than the front-page, use: if( !is_front_page() && is_active_sidebar(‘your-sidebar’) ) { $class=”your-class … Read more
is_page() requires WP_Query to be initialized and I assume your code runs before this. You can use this function within the filter callback instead: add_filter(‘the_content’, function($c){ return is_page() ? luc_add_cutom_fields_to_content($c) : $c; });
Your code seems identical to FacetWP’s. The only variable I can think of is code placement. You might not be placing the code where it belongs (functions.php or a plugin). A quick fix would be adding their code to your theme’s functions.php: function fwp_add_facet_labels() { ?> <script> (function($) { $(document).on(‘facetwp-loaded’, function() { $(‘.facetwp-facet’).each(function() { var … Read more
According to the docs the input parameters can be: has_tag( string|int|array $tag = ”, int|object $post = null ) so you could try e.g. if( has_tag( ‘test’ ) ) { … } to check if the current post has the test tag.
[EDIT] Here is the modified code: $post_id = get_the_ID(); // ID of the current post. $user_id = get_current_user_id(); // ID of the current user. $post_author_id = get_post_field( ‘post_author’, $post_id ); $is_post_author = ( $user_id && $post_author_id == $user_id ); $can_comment = $is_post_author; /* * If $can_comment is not yet TRUE, then it’s because either: * … Read more
