Hallo zusammen!
In meinem neuen Theme möchte ich es einrichten, das in einem Widget statt einer Kategorie die Artikeln aus mehreren Kategorien erscheinen.
Ich habe es mir anhand eines vorher genutzten Themes schon soweit umgebaut, das ich im Backend die ID's eingeben kann. Nur leider erscheint im Frontend nichts, wenn ich das Auswahlfeld für die einzelne Kategorie leer lasse.
Der Code schaut so aus:
PHP
/** * Featured Posts widget */class colormag_featured_posts_widget extends WP_Widget {
function __construct() { $widget_ops = array( 'classname' => 'widget_featured_posts widget_featured_meta', 'description' =>__( 'Display latest posts or posts of specific category.' , 'colormag') ); $control_ops = array( 'width' => 200, 'height' =>250 ); parent::__construct( false,$name= __( 'TG: Featured Posts (Style 1)', 'colormag' ),$widget_ops); }
function form( $instance ) { $tg_defaults['title'] = ''; $tg_defaults['text'] = ''; $tg_defaults['number'] = 4; $tg_defaults['type'] = 'latest'; $tg_defaults['category'] = ''; $tg_defaults['cats'] = ''; $instance = wp_parse_args( (array) $instance, $tg_defaults ); $title = esc_attr( $instance[ 'title' ] ); $text = esc_textarea($instance['text']); $number = $instance['number']; $type = $instance['type']; $category = $instance['category']; $cats = $instance['cats']; ?> <p><?php _e( 'Layout will be as below:', 'colormag' ) ?></p> <div style="text-align: center;"><img src="<?php echo get_template_directory_uri() .

function update( $new_instance, $old_instance ) { $instance = $old_instance; $instance[ 'title' ] = strip_tags( $new_instance[ 'title' ] ); if ( current_user_can('unfiltered_html') ) $instance['text'] = $new_instance['text']; else $instance['text'] = stripslashes( wp_filter_post_kses( addslashes($new_instance['text']) ) ); $instance[ 'number' ] = absint( $new_instance[ 'number' ] ); $instance[ 'type' ] = $new_instance[ 'type' ]; $instance[ 'category' ] = $new_instance[ 'category' ]; $instance[ 'cats' ] = $new_instance[ 'cats' ]; return $instance; }
