我正在尝试开发一个插件来帮助上传与之相关的图像标题和描述。之后在前端显示相同。这是我的代码：
<?php
/*
Plugin Name: Custom News Scroller
Plugin URI: http://url.com
Description: description.
Author: name
Version: 1.0
Author URI: http://url.com
*/
class CustomNewsScrollerWidget extends WP_Widget
{
function CustomNewsScrollerWidget() {
$widget_options = array(
'classname' => 'custom-news-scroller-widget',
'description' => 'Helps to scroll news'
);
parent::WP_Widget('custom_news_scroller_widget', 'Custom News Scroller', $widget_options);
}
function widget( $args, $instance ) {
extract ( $args, EXTR_SKIP );
$title = ( $instance['title'] ) ? $instance['title'] : 'A simple widget';
$body = ( $instance['body'] ) ? $instance['body'] : 'A simple message'
?>
<?php echo $before_widget ?>
<?php echo $before_title . $title . $after_title ?>
<p><?php echo $body ?></p>
<?php
}
function update() {
}
function form($instance) {
?>
<label for="<?php echo $this->get_field_id('title'); ?>">
Title:
<input id="<?php echo $this->get_field_id('title'); ?>"
name="<?php echo $this->get_field_name('title'); ?>"
value="<?php echo esc_attr($instance['title']) ?>" />
</label>
<label for="<?php echo $this->get_field_id('description'); ?>">
Description:
<input id="<?php echo $this->get_field_id('description'); ?>"
name="<?php echo $this->get_field_name('description'); ?>"
value="<?php echo esc_attr($instance['description']) ?>" />
</label>
<?php
}
}
function custom_news_scroller_widget_init() {
register_widget("CustomNewsScrollerWidget");
}
add_action('widgets_init','custom_news_scroller_widget_init');
我有一个输入标题和描述的 2 输入文本框。如何将这些信息存储在数据库中？以及如何从数据库中检索相同的内容？
