我创建了一个自定义窗口小部件,其中一个字段是一个完整的电话号码(代码中的全电话)。它的用途是侧边栏的号召性用语小工具(例如输入数字,某些文字,按钮网址等)。有没有办法从这个字段中获取内容(如果它在窗口小部件中填充)并将其添加到模板的某个位置?我想在页脚中添加一个电话号码,但不是在页脚中对其进行硬编码,我认为只要抓住已经在号召性用语中输入的号码就行了。这可行吗?感谢。
这是我的小部件代码:
add_action( 'widgets_init', 'sidebarctawidget' );
function sidebarctawidget() {
register_widget( 'sidebarctawidget' );
}
class sidebarctawidget extends WP_Widget {
function sidebarctawidget() {
$widget_ops = array( 'classname' => 'sidebarctawidget', 'description' => __('A widget for the sidebar call to actions ', 'sidebarctawidget') );
$control_ops = array( 'width' => 300, 'height' => 350, 'id_base' => 'sidebarctawidget' );
$this->WP_Widget( 'sidebarctawidget', __('Sidebar Call to Action', 'sidebarctawidget'), $widget_ops, $control_ops );
}
function widget( $args, $instance ) {
extract( $args );
//Our variables from the widget settings.
$title = apply_filters('widget_title', $instance['title'] );
$text = $instance['text'];
$prefix = $instance['prefix'];
$number = $instance['number'];
$fullnumber = $instance['fullnumber'];
$url = $instance['url'];
echo $before_widget;
echo '<div class="sidebarcta">';
// Display the title
if ( $title )
echo $before_title . $title . $after_title;
//Display the text
if ( $text )
printf( '<p class="text">' . __('%1$s', 'sidebarctawidget') . '</p>', $text );
//Display the text
if ( $prefix )
printf( '<span class="prefix">' . __('%1$s-', 'sidebarctawidget') . '</span>', $prefix );
//Display the text
if ( $number )
printf( '<span class="number">' . __('%1$s', 'sidebarctawidget') . '</span>', $number );
//Display the text
if ( $fullnumber )
printf( '<p class="fullnumber">' . __('(%1$s)', 'sidebarctawidget') . '</p>', $fullnumber );
//Display the button and URL
if ( $url )
printf( '<a class="button" href="%1$s">' . __('Learn More', 'sidebarctawidget') . '</a>', $url );
echo '</div>';
echo $after_widget;
}
//Update the widget
function update( $new_instance, $old_instance ) {
$instance = $old_instance;
//Strip tags from title and name to remove HTML
$instance['title'] = strip_tags( $new_instance['title'] );
$instance['text'] = strip_tags( $new_instance['text'] );
$instance['prefix'] = strip_tags( $new_instance['prefix'] );
$instance['number'] = strip_tags( $new_instance['number'] );
$instance['fullnumber'] = strip_tags( $new_instance['fullnumber'] );
$instance['url'] = strip_tags( $new_instance['url'] );
return $instance;
}
function form( $instance ) {
//Set up some default widget settings.
$defaults = array( 'title' => __('Get Connected TODAY!', 'sidebarctawidget') );
$instance = wp_parse_args( (array) $instance, $defaults ); ?>
