Hi all, I’ve created a custom widget to display some info, it works ok in the back-end but I can’t display the data on the front-end. It worked fine when I was using simple fields but I realized that repeater fields are better for this.
This is what I have so far…
add_action( 'widgets_init', 'services_widget' );
function services_widget() {
register_widget( 'services_widget' );
}
class services_widget extends WP_Widget {
public function __construct() {
$widget_ops = array(
'classname' => 'services_widget',
'description' => 'Add a service description.'
);
$control_ops = array( 'width' => 400, 'height' => 350 );
parent::__construct( 'services_widget', 'Services', $widget_ops, $control_ops );
}
public function widget( $args, $instance ) {
$title = apply_filters( 'widget_title', empty( $instance['title'] ) ? '' : $instance['title'], $instance, $this->id_base );
echo $args['before_widget'];
if ( ! empty( $title ) ) {
echo $args['before_title'] . $title . $args['after_title'];
}
if( have_rows('service', 'widget_' . $widget_id) ):
echo '<ul>';
while ( have_rows('service', 'widget_' . $widget_id) ) : the_row();
echo '<li class="service one-half">';
$title = get_sub_field( 'title', 'widget_' . $widget_id );
$body = get_sub_field( 'body', 'widget_' . $widget_id );
$button = get_sub_field( 'button', 'widget_' . $widget_id );
$button_link = get_sub_field( 'button_link', 'widget_' . $widget_id );
if( $title ) {
echo '<h4>' . $title . '</h4>';
}
if( $body ) {
echo '<p>' . $body . '</p>';
}
if( $body ) {
echo '<a class="more" href="' . $button_link . '">' .$button . '</a>';
}
echo '</li><div class="clearfix"></div></ul>';
endwhile;
endif;
echo $args['after_widget'];
}
public function form( $instance ) {
$instance = wp_parse_args( (array) $instance, array( 'title' => '', 'text' => '' ) );
$filter = isset( $instance['filter'] ) ? $instance['filter'] : 0;
$title = sanitize_text_field( $instance['title'] );
?>
<p><label for="<?php echo $this->get_field_id('title'); ?>"><?php _e('Title:'); ?></label>
<input class="widefat" id="<?php echo $this->get_field_id('title'); ?>" name="<?php echo $this->get_field_name('title'); ?>" type="text" value="<?php echo esc_attr($title); ?>" /></p>
<p><input id="<?php echo $this->get_field_id('filter'); ?>" name="<?php echo $this->get_field_name('filter'); ?>" type="checkbox"<?php checked( $filter ); ?> /> <label for="<?php echo $this->get_field_id('filter'); ?>"><?php _e('Automatically add paragraphs'); ?></label></p>
<?php
}
public function update( $new_instance, $old_instance ) {
$instance = $old_instance;
$instance['title'] = sanitize_text_field( $new_instance['title'] );
if ( current_user_can( 'unfiltered_html' ) ) {
$instance['text'] = $new_instance['text'];
} else {
$instance['text'] = wp_kses_post( $new_instance['text'] );
}
$instance['filter'] = ! empty( $new_instance['filter'] );
return $instance;
}
}
I appreciate any help with this, I’m sure there’s something wrong with the code, it’s my first time creating a widget.
