🌐 Web query:
WordPress developer reference strip_shortcodes registered shortcode tags implementation
💡 Result:
The strip_shortcodes function in WordPress is designed to remove shortcode tags from a given content string [1][2]. A critical implementation detail is that it only removes shortcodes that are currently registered in the global $shortcode_tags array [1][3][2]. If a shortcode is present in the content but is not registered (for example, if the plugin providing it is deactivated), strip_shortcodes will not remove it [2]. Key implementation mechanics include: 1. Global Check: The function accesses the global $shortcode_tags array to determine which shortcode tags are currently known to WordPress [1][3]. 2. Performance Optimization: It first checks if the content contains a '[' character [1]. If not, or if $shortcode_tags is empty, it returns the content immediately without processing [1][3]. 3. Filtering: It uses the strip_shortcodes_tagnames filter, which allows developers to programmatically modify the list of tags intended for removal before the regex processing occurs [1][3]. 4. Regex Matching: It identifies potential shortcodes in the content using a regular expression pattern generated by get_shortcode_regex [1][3]. This ensures that only patterns matching the structure of registered shortcodes are targeted [2]. 5. Stripping: It uses preg_replace_callback with the strip_shortcode_tag function to remove the matched tags while preserving non-shortcode text [1][3]. 6. Safety: The function performs steps to unescape invalid shortcodes and handle shortcodes within HTML tags to prevent breaking markup (e.g., conditional comments) [1][3]. Because this function relies on the active state of shortcode registrations, it is common practice in some scenarios to manually register "dummy" shortcodes if you need to strip them from content when the original plugin is no longer active [2].

Sanitize all shortcode-shaped header text before storage.
strip_shortcodes() removes only currently registered shortcode tags. An unregistered value such as [future_tag]text[/future_tag] remains stored and can be processed by a later do_shortcode() call if future_tag is registered. Use a sanitizer that neutralizes all shortcode-shaped header input, and add a regression test for a tag registered after storage.
