That’s because get_post_meta_by_key() isn’t a WordPress function. What you’re likely looking for is get_post_meta(): add_action( ‘woocommerce_after_shop_loop_item’, ‘display_author’ ); function display_author() { global $post; echo get_post_meta( $post->ID, ‘author’, true ); } Not tested, because I don’t have a WooCommerce install handy (and WooCommerce specifics are off-topic here anyway) but this is pretty standard so it should … Read more
The ‘contact’ function should return a string instead of echoing. So the above, should look like: function contact() { $contact = get_field(‘contact’,options); return $contact; } add_shortcode(‘contact’, ‘contact’); Shortcodes are written by providing a handler function. Shortcode handlers are broadly similar to WordPress filters: they accept parameters (attributes) and return a result (the shortcode output). See … Read more
The functions.php file doesn’t know where you want that code to be shown on the front end. You need to put the code into a template page (ie the woocommerce account page) or attach it to that page with a woocommerce hook to the template. You’ll need to add it into a function to properly … Read more
To change the text of the “Read More” link, you simply need to hook into the_content_more_link at a higher priority. You can add this to your child theme functions.php file and it should replace the “Read More” text with “Your Preferred Link Text”. add_filter( ‘the_content_more_link’, ‘wpse_260911_more_link’, 11, 2 ); function wpse_260911_more_link( $more_link, $not_used ) { … Read more
The is_single is WordPress function so you should add parentheses after it as displayed in the following correct code. <?php if ( ! is_single() ){ ?> <meta property=”og:image” content=”<?php echo get_template_directory_uri(); ?>/images/image.png”/> <?php } ?>
You will want to use get_template_directory_uri() to load files from the parent theme. get_stylesheet_directory_uri() is for the current theme, which is your child theme.
Doing this with a WordPress hook would be difficult to do reliably. But it’s straightforward with jQuery and some CSS. jQuery(‘a’).wrap(‘<div class=”brackets”/>’); .brackets:before { content: “\005B”; } .brackets:after { content: “\005D”; }
wp_tag_cloud() accepts a separator parameter, so you can modify your call like this: wp_tag_cloud( array( ‘separator’ => “, “, // Default value: “\n” ‘unit’ => ‘px’, // font sizing choice (pt, em, px, etc) ‘include’ => $tag_ids, // ID’s of tags to include, displays none except these ) );
You should use standard php function if class_exists(‘WC_Product_Variation’) { …}
*Without quotes PHP interprets the REQUEST_URI as a constant** but corrects your typo error if there is no such constant and interprets it as string. When error_reporting includes E_NOTICE, you would probably get an error such as: Notice: Use of undefined constant REQUEST_URI – assumed ‘REQUEST_URI’ in <file path> on line <line number> But if … Read more
