You should do this in the shortcode/plugin itself. An easy way to do it may be something like this: // if the shortcodes empty: if ( empty( $shortcode_content ) ) { // set a default nothing found message $shortcode_content=”Sorry! Nothing found”; } return $shortcode_content;
Not quite like that, but you can achieve the same result if you use a pre-defined value or argument in your shortcode to act as a “flag”: [authoorsposts author=”post”] …then in your handler: function wpse_209684_author( $atts ) { if ( ! empty( $atts[‘author’] ) ) { $author = $atts[‘author’]; if ( $author === ‘post’ ) … Read more
You don’t have any validation mechanism. Your logic should be somewhat along those lines Submit form Check submitted fields ($_POST) against expected values If all looks good send If something is not as expected, log error ( you can use WP_Error() ) and rebuild form showing error message (and maybe repopulating fields with previous “good” … Read more
I checked your code in my install. It works, except that you made a typo (missing backslash): [icon]cog[/icon] Few notes: You must make sure to enqueue the Font Awsesome stylesheet. You must close the shortcode, like: [icon]cog[/icon] Remember to escape the class name with esc_attr(). Another shortcode idea: [fa icon=”cog”]
This is more about php than wp, but ob_get_contents returns the buffer without clearing it. So you get your buffer content twice. Use ob_get_clean to erase the buffer on returning it.
This will list the 3 most recent posts from the post type us_portfolio. <?php $args = array( ‘posts_per_page’ => 3, ‘post_type’ => ‘us_portfolio’ ); $custom_query = new WP_Query($args); while ($custom_query->have_posts()) : $custom_query->the_post(); ?> <div class=”image bg-image” style=”background-image: url(‘<?php the_post_thumbnail_url(‘full’); ?>’)”></div> <?php the_category(); ?> <h3> <a title=”<?php the_title(); ?>” href=”https://wordpress.stackexchange.com/questions/289627/<?php the_permalink(); ?>”> <?php the_title(); ?> </a> … Read more
I’m afraid hiding the shortcode once the plugin is deactivated is simply not possible. The only way to “hide” a shortcode from the content is to register the shortcode with a calback that returns nothing, as in: add_shortcode( ‘related’, function(){ return null; } ); But of course you cannot do that without an active plugin. … Read more
The var_dump() before using shortcode_atts() reveals the problem. Lets look at that output in a more readable format: array(5) { [0] => string(42) “phonePrefix=”0581″,phoneFlatOption=”true”,” [1]=> string(21) “accessModeDsl=”true”,” [2]=> string(24) “accessModeCable=”false”,” [3]=> string(22) “accessModeLte=”false”,” [“accessmodesat”]=> string(5) “false” } As you can see, the attributes are not being parsed correctly. Instead of ‘attribute’ => ‘value’ you’re getting … Read more
If I got it right – I can only use wc_get_product if the current page is using the WooCommerce plugin. Since it’s a post page it does not includes the WooCommerce plugin and hence I can’t use the wc_get_product. (Please currect me if I’m wrong – I’m here to learn 😀 ) You are wrong … Read more
This problem has pretty simple explanation 😉 All you need to do is to take a look at Codex page for WP_Query and read about offset parameter: offset (int) – number of post to displace or pass over. Warning: Setting the offset parameter overrides/ignores the paged parameter and breaks pagination (Click here for a workaround). … Read more
