Content filter hook in wordpress
10.12.25
``` Add Conditional Logic (Optional but Recommended): To prevent unintended filtering of content in sidebars, footers, or custom loops, it's crucial to add conditional checks within your callback function. Common conditionals include is_main_query(), in_the_loop(), is_singular(), is_single(), or is_page() [1]. function filter_the_content_in_the_main_loop( $content ) { // Check if we're inside the main loop in a single Post or Page. if ( ( is_single() || is_page() ) && in_the_loop() && is_main_query() ) { return $content . esc_html__( "I'm filtering the content inside the main loop", "my-textdomain" ); } return $content; } add_filter( 'the_content', 'filter_the_content_in_the_main_loop', 1 ); ```
