我正在创建我的第一个wordpress插件,它应该在激活时创建一个页面(相对较大)。
目前我可以创建一个文件:
$_p['post_title'] = $the_page_title;
$_p['post_content'] = '<h1>PAGE CONTENT</h1>';
$_p['post_status'] = 'publish';
$_p['post_type'] = 'page';
$_p['comment_status'] = 'closed';
$_p['ping_status'] = 'closed';
$_p['post_category'] = array(1); // the default 'Uncatrgorised'
// Insert the post into the database
$the_page_id = wp_insert_post( $_p );
问题是,我不能把文件的所有内容(这是大)作为字符串'post_content'索引。我想知道是否有一种方法,我可以简单地:
- 'post_content' =>链接到我的插件目录
- 'post_content' =>调用一个返回html内容字符串的函数:([最坏的情况]
- 或者,一些更简单的方法来实现目标。
请帮帮我。
我解决这个问题的方法是:
//**SECTION : 1**
function user_login_foo() {
return get_login_form(); // get_login_form() function will return the html template i want to display.
}
add_shortcode('user_login', 'user_login_foo'); // created a shortcode
**// SECTION: 2**
function get_login_form()
{
ob_start(); ?>
<h3><?php __('Login'); ?></h3>
<form action="" method="post">
<fieldset>
// the login form comes here
</fieldset>
</form>
<?php
return ob_get_clean();
}
function validate_login_user() {
// the login validation logic comes here
}
add_action('init', 'validate_login_user');
SECTION 1:注册了一个短代码,它将调用函数[例如,foo1()]并返回值。函数foo1()调用另一个函数[例如foo2()],该函数返回一个干净的html表单以响应调用(当调用短代码时)。
第2节:在本节中,我定义了函数foo2(),其中定义了html表单[login form]并返回给foo1()[显示它的地方]。然后我创建了一个动作[add_action('init', 'validate_login_user');在初始化时调用函数validate_login_user(),在这个函数中,我检查了isset(METHOD[username])和isset(METHOD[password]),然后执行相应的逻辑。
就像这样,我为每个我想在激活时创建的页面创建了多个[短代码],然后:
**step 1:** register_activation_hook(__FILE__,'activation_plugin');
**step 2:** activation_plugin(){
'390' => [ // '390' is page id
'post_title' => 'Page title say login',
'post_content' => "[user_login]",
'post_status' => 'publish',
'post_type' => 'page',
'comment_status' => 'closed',
'ping_status' => 'closed',
'post_category' => array(1)
],
'391' => [
'post_title' => 'page title 2',
'post_content' => "[short_code2]",
'post_status' => 'publish',
'post_type' => 'page',
'comment_status' => 'closed',
'ping_status' => 'closed',
'post_category' => array(1)
],
// like this add multiple shortcodes
}
// this foreach will create all the pages
foreach ($_ as $key => $value) {
$the_page_title = $value['post_title'];
$the_page_name = $value['post_title'];
// the menu entry...
delete_option($value['post_title']);
add_option($value['post_title'], $the_page_title, '', 'yes');
// the slug...
delete_option($value['post_title']);
add_option($value['post_title'], $the_page_name, '', 'yes');
// the id...
delete_option($key);
add_option($key, '0', '', 'yes');
$the_page = get_page_by_title( $the_page_title );
if ( ! $the_page ) {
$the_page_id = wp_insert_post( $value );
}
else {
$the_page_id = $the_page->ID;
$the_page->post_status = 'publish';
$the_page_id = wp_update_post( $the_page );
}
delete_option( $key );
add_option( $key, $the_page_id );
}
创建关于插件激活的页面
$page_content= 'Content of page';
$demo_page = array(
'comment_status' => 'closed',
'ping_status' => 'closed' ,
'post_author' => 1,
'post_content' => $page_content,
'post_date' => date('Y-m-d H:i:s'),
'post_name' => 'page_name',//display on address bar
'post_status' => 'publish' ,
'post_title' => 'Page Display Name',
'post_type' => 'page',
);
//insert page and save the id
$demo_page_value = wp_insert_post( $demo_page, false );
//save the id in the database
update_option( 'testpage', $$demo_page_value );
