All filters applied to the ‘the_content’ hook (including shortcode rendering) are not applied when you call get_the_content(). This is why you get raw shortcode from your content. You could use the_content() instead, or use apply_filters directly in your template. In other words, replace this line: echo ‘<p class=”p-paragraph” style=”text-align:left”>’. get_the_content().'</p>’; with either (preferred method): echo … Read more
If you look at the gallery shortcode function the opening div (to match that closer you’re missing) looks like this: $gallery_div = “<div id=’$selector’ class=”gallery galleryid-{$id} gallery-columns-{$columns} gallery-size-{$size_class}”>”; then this filter is run $output = apply_filters( ‘gallery_style’, $gallery_style . $gallery_div ); More than likely there’s code somewhere in your theme or a plugin that’s messing … Read more
As I pointed in the comments, if for example you’re displaying 9 posts per page, which means there would be 3 gallery images shown per page, and you want page #1 to show images 1-3, page #2 to show images 4-6, and so on, then you would want to paginate the gallery images: // the … Read more
wp.media is the JavaScript API WordPress uses to display the media library modal. You can use it yourself by enqueueing a custom JS script on your admin page: wp_enqueue_script(‘media-upload’); wp_enqueue_media(); wp_enqueue_script( ‘pb-admin-script’, ‘admin.js’, array( ‘jquery’, ) ); Then work with it like this: HTML: <button class=”upload_image_button button button-primary”> <?php _e(‘Upload Image’, ‘pb’); ?> </button> <img … Read more
What’s wrong with the built-in gallery functionality? Seems to match your description pretty well. 😉
<a rel=”lightbox” href=”https://wordpress.stackexchange.com/questions/10191/<?php $image_id = get_post_thumbnail_id(); $image_url = wp_get_attachment_image_src($image_id,”large’, true); echo $image_url[0]; ?>”> <?php the_post_thumbnail(‘thumbnail’); ?> </a> Yeah the above (posted by @null) is correct on getting the url, here it is all put together. Including the rel=lightbox. I call to WP’s large image size here personally for the lightbox image to be linked to. … Read more
<?php function modified_post_gallery( $blank = NULL, $attr ) { echo ‘<pre>’; print_r( $attr ); echo ‘</pre>’; } add_filter( ‘post_gallery’, ‘modified_post_gallery’, 10, 2); ?> In media.php it shows the filter like this: // Allow plugins/themes to override the default gallery template. $output = apply_filters(‘post_gallery’, ”, $attr); Its passing two variables not one and $attr is on … Read more
This is all sorts of wrong, you need to first decide if you want to use posts, pages or custom post types. You alluded at the end that you wanted a new tab like you have seen in some themes, this would be the right way to do it using Custom Post Types. You can … Read more
This is a lot of customization, but can definitely be done. I do not know of a plugin that will do this for you: Each slideshow is a category. Each slide is a post. Build a custom template for the post, so it displays the navigation and the content exactly how you want it. Design … Read more
Attachments are post objects, with post_parent set to the ID of the post they belong to (ie your ‘session’). The WP Codex page on wp_get_attachment_image() has an example almost exactly like what you’re trying to do: https://codex.wordpress.org/Function_Reference/wp_get_attachment_image#Display_all_images_as_a_list Make sure that you replace the post_parent parameter in that example with the ID of the current session … Read more
