Add wp_reset_postdata() after your while loop: endwhile; wp_reset_postdata(); endif; This will ensure that, after your shortcode runs, the actual current post is restored, so that any template tags display the right data.
Transients are probably not the way to go here. From what I understand: You want to know if a post has a shortcode by doing some form of look up You want to be able to get a list of permalinks / posts that have this shortcode. Here’s what I suggest. /** * Checks for … Read more
If your only issue is that the format is incorrect then switch it in the_content hook with the correct version. Non-local content: Place in a plugin or functions.php // hook earlier than 10 add_filter(‘the_content’, ‘wpse_20160110_the_content_fix_audio’, 0); function wpse_20160110_the_content_fix_audio($content){ return str_replace ( ‘[audio:’, ‘[audio src=”https://wordpress.stackexchange.com/questions/214052/, $content ); }
I would prefer two array of images, captions. For example: I have added comments on the code for better understanding. function wpse216239_slider_shortcode( $atts , $content = null ) { // Attributes $atts = shortcode_atts( array( ‘slides’ => ”, // one master attribute for slides ‘captions’ => ” // one master attribute for captions ), $atts, … Read more
I wasn’t able to directly add a repeating field (with let’s say a + button) but I was able to create a 2 step process whereby the end-user can use a numeric field to set the number of repeatable areas on the next screen: Step 1 – Select Shortcode Step 2 – Shortcode Builder Step … Read more
Nope, that won’t work. By the time WordPress starts evaluating the shortcode in your content, the head of the site has already been assembled, so you can no longer add an action to it. Looking at the execution order of hooks gives you a clue how to do this. First, you must avoid echoing scripts. … Read more
Uninitialized string offset: 0 This error is showing because there is an empty value. Try checking if the value is !empty() (not empty) first. Here’s the source code you provide in your question with my update. function cf_form_message() { global $errors; if ( is_wp_error( $errors ) && empty( $errors -> errors ) ) { ?> … Read more
Oops – too late to withdraw the question, I guess – but realized while out taking a walk that the answer was obvious: The query within the main query creates an infinite loop, since the post containing the shortcode would be within the main loop, so opens a hole in the universe etc. Will be … Read more
It should be as simple as this: function item_count() { $dir=”/PATH TO DIRECTORY/”; $filecount = 0; $d = dir( $dir ); while ( $f = $d->read() ) { if ( ( $f!= “.” ) && ( $f!= “..” ) ) { if( ! is_dir( $f ) ) { $filecount++; } } } return ‘(‘ . … Read more
The shortcodes only run if they are used in the WordPress environment. It appears you are using the shortcode in a page that the WordPress’s engine has not been loaded. Also, always store your data in a variable and then return the value instead of using echo: function sac_form() { $data=” <html> <head></head> <body> <form> … Read more
