我有一个主题,扩展Visual Composer插件与首页上的滑块.该滑块将显示来自五个不同客户的五个推荐.我想将每个推荐的特色图片添加为滑块中的缩略图.
function jo_customers_testimonials_slider( $atts ) { extract( shortcode_atts( array( 'limit' => 5,"widget_title" => __('What Are People Saying','jo'),'text_color' => "#000" ),$atts ) ); $content = ""; $loopArgs = array( "post_type" => "customers","posts_per_page" => $limit,'ignore_sticky_posts' => 1 ); $postsLoop = new WP_Query( $loopArgs ); $content = ""; $content .= '...'; $content .= '...'; $content .= '...'; wp_reset_query(); return $content; } add_shortcode( 'jo_customers_testimonials_slider','jo_customers_testimonials_slider' );
function jo_customers_testimonials_slider_with_thumbnail( $atts ) { extract( shortcode_atts( array( 'limit' => 5,'ignore_sticky_posts' => 1 ); $postsLoop = new WP_Query( $loopArgs ); $content = ""; $content .= '...'; $content .= get_the_post_thumbnail( get_the_ID(),'thumbnail' ); $content .= '...'; $content .= '...'; wp_reset_query(); return $content; } add_shortcode( 'jo_customers_testimonials_slider','jo_customers_testimonials_slider_with_thumbnail' );
在理论上,我的functions.PHP文件中的函数应该覆盖父主题的短代码.但是当我使用这个代码时,似乎没有发生任何事情.我究竟做错了什么?
编辑:
试过这段代码,但仍然不行.
function wpa_add_child_shortcodes(){ remove_shortcode('jo_customers_testimonials_slider'); add_shortcode( 'jo_customers_testimonials_slider','jo_customers_testimonials_slider_with_thumbnail' ); } add_action( 'after_setup_theme','wpa_add_child_shortcodes' );
也改了
add_action(‘after_setup_theme’,’wpa_add_child_shortcodes’);至
add_action(‘init’,’wpa_add_child_shortcodes’);
,但结果没有差异.
编辑2(带解决方案):
更改add_action(‘after_setup_theme’,’wpa_add_child_shortcodes’); to add_action(‘wp_loaded’,’wpa_add_child_shortcodes’);解决了
你需要像这样调用
remove_shortcode();:remove_shortcode(‘jo_customers_testimonials_slider’);在您添加新的短代码之前,他将使用相同的名称来“覆盖”它.
您还需要在父主题运行后调用它,以便我们在名为wp_loaded的动作钩上触发
function overwrite_shortcode() { function jo_customers_testimonials_slider_with_thumbnail( $atts ) { extract( shortcode_atts( array( 'limit' => 5,'thumbnail' ); $content .= '...'; $content .= '...'; wp_reset_query(); return $content; } remove_shortcode('jo_customers_testimonials_slider'); add_shortcode( 'jo_customers_testimonials_slider','jo_customers_testimonials_slider_with_thumbnail' ); } add_action( 'wp_loaded','overwrite_shortcode' );
