多个设置 Wordpress 选项页面插件 [英] Multiple settings Wordpress Options Page plugin
问题描述
我想为我的插件制作一个包含多个设置的选项页面.我想使用此代码作为开始:http://codex.wordpress.org/Creating_Options_Pages#Example_.232
<div class="wrap"><?php screen_icon();?><h2>设置</h2><form method="post" action="options.php"><?php//这会打印出所有隐藏的设置字段settings_fields('test_option_group');do_settings_sections('test-setting-admin');?><?php submit_button();?></表单><?php}公共函数 page_init(){register_setting('test_option_group', 'array_key', array($this, 'check_ID'));add_settings_section('setting_section_id','环境'，数组($this，'print_section_info')，测试设置管理员");add_settings_field('some_id','一些 ID(标题)',数组($this, 'create_an_id_field'),'测试设置管理员','setting_section_id');}公共函数 check_ID($input){if(is_numeric($input['some_id'])){$mid = $input['some_id'];if(get_option('test_some_id') === FALSE){add_option('test_some_id', $mid);}别的{update_option('test_some_id', $mid);}}别的{$mid = '';}返回 $mid;}公共函数print_section_info(){打印 '在下面输入您的设置:';}公共函数 create_an_id_field(){?><input type="text" id="input_whatever_unique_id_I_want" name="array_key[some_id]" value="<?=get_option('test_some_id');?>"/><?php}}$wctest = 新 wctest();
一切都如页面上的代码所示，但我想添加第二个设置.如何添加另一个设置部分和设置字段并能够保护这些值?我已经困惑了半天了，但没有运气.
有人可以帮我吗?这是我的第一个插件，如果我理解了这部分，我可以做剩下的.
我刚刚修改了 Codex 中的示例:Creating_Options_Pages#Example_.232.现在它包括第二个设置字段.消毒功能更易于理解和扩展.还更改了变量的名称并在代码中添加了文档.我认为现在更容易遵循逻辑.这是完整的:
options = get_option('my_option_name');?><div class="wrap"><?php screen_icon();?><h2>我的设置</h2><form method="post" action="options.php"><?php//这会打印出所有隐藏的设置字段settings_fields('my_option_group');do_settings_sections('我的设置管理员');提交按钮()；?></表单><?php}/*** 注册并添加设置*/公共函数 page_init(){寄存器设置('my_option_group',//选项组'my_option_name',//选项名称array( $this, 'sanitize' )//消毒);add_settings_section('setting_section_id',//ID'我的自定义设置',//标题array( $this, 'print_section_info' ),//回调'my-setting-admin'//页面);add_settings_field('id_number',//ID'身份证号码',//标题array( $this, 'id_number_callback' ),//回调'my-setting-admin',//页面'setting_section_id'//部分);add_settings_field('标题'，'标题'，数组( $this, 'title_callback' ),'我的设置管理员','setting_section_id');}/*** 根据需要清理每个设置字段** @param array $input 包含所有设置字段作为数组键*/公共函数消毒( $input ){$new_input = array();if( isset( $input['id_number'] ) )$new_input['id_number'] = absint( $input['id_number'] );if( isset( $input['title'] ) )$new_input['title'] = sanitize_text_field( $input['title'] );返回 $new_input;}/*** 打印部分文本*/公共函数print_section_info(){打印 '在下面输入您的设置:';}/*** 获取设置选项数组并打印其值之一*/公共函数 id_number_callback(){打印输出('<input type="text" id="id_number" name="my_option_name[id_number]" value="%s"/>',isset( $this->options['id_number'] ) ?esc_attr( $this->options['id_number']) : '');}/*** 获取设置选项数组并打印其值之一*/公共函数 title_callback(){打印输出('<input type="text" id="title" name="my_option_name[title]" value="%s"/>',isset( $this->options['title'] ) ?esc_attr( $this->options['title']) : '');}}if( is_admin() )$my_settings_page = new MySettingsPage();
如果您想添加新的设置部分，只需将所需的设置字段指向新部分即可.
在需要的地方使用:get_option('my_option_name');拉取信息.
I want to make an Options page with multiple settings for my plugin. I want to use this code as a start: http://codex.wordpress.org/Creating_Options_Pages#Example_.232
<?php
class wctest{
public function __construct(){
if(is_admin()){
add_action('admin_menu', array($this, 'add_plugin_page'));
add_action('admin_init', array($this, 'page_init'));
}
}
public function add_plugin_page(){
// This page will be under "Settings"
add_options_page('Settings Admin', 'Settings', 'manage_options', 'test-setting-admin', array($this, 'create_admin_page'));
}
public function create_admin_page(){
?>
<div class="wrap">
<?php screen_icon(); ?>
<h2>Settings</h2>
<form method="post" action="options.php">
<?php
// This prints out all hidden setting fields
settings_fields('test_option_group');
do_settings_sections('test-setting-admin');
?>
<?php submit_button(); ?>
</form>
</div>
<?php
}
public function page_init(){
register_setting('test_option_group', 'array_key', array($this, 'check_ID'));
add_settings_section(
'setting_section_id',
'Setting',
array($this, 'print_section_info'),
'test-setting-admin'
);
add_settings_field(
'some_id',
'Some ID(Title)',
array($this, 'create_an_id_field'),
'test-setting-admin',
'setting_section_id'
);
}
public function check_ID($input){
if(is_numeric($input['some_id'])){
$mid = $input['some_id'];
if(get_option('test_some_id') === FALSE){
add_option('test_some_id', $mid);
}else{
update_option('test_some_id', $mid);
}
}else{
$mid = '';
}
return $mid;
}
public function print_section_info(){
print 'Enter your setting below:';
}
public function create_an_id_field(){
?><input type="text" id="input_whatever_unique_id_I_want" name="array_key[some_id]" value="<?=get_option('test_some_id');?>" /><?php
}
}
$wctest = new wctest();
Everything works as shown below the code on the page, but I want to add a second setting. How do I add another settings section and a settings field and being able to safe the values? I have been puzzling for half a day now, but no luck.
Could someone help me out please? This is my first plugin and if I understand this part I can do the rest.
I just modified the example in the Codex: Creating_Options_Pages#Example_.232. Now it includes a second Settings Field. The sanitization function is simpler to understand and expand. Also changed the names of the variables and added documentation in the code. I think it's easier to follow the logic now. Here it is in full:
<?php
class MySettingsPage
{
/**
* Holds the values to be used in the fields callbacks
*/
private $options;
/**
* Start up
*/
public function __construct()
{
add_action( 'admin_menu', array( $this, 'add_plugin_page' ) );
add_action( 'admin_init', array( $this, 'page_init' ) );
}
/**
* Add options page
*/
public function add_plugin_page()
{
// This page will be under "Settings"
add_options_page(
'Settings Admin',
'My Settings',
'manage_options',
'my-setting-admin',
array( $this, 'create_admin_page' )
);
}
/**
* Options page callback
*/
public function create_admin_page()
{
// Set class property
$this->options = get_option( 'my_option_name' );
?>
<div class="wrap">
<?php screen_icon(); ?>
<h2>My Settings</h2>
<form method="post" action="options.php">
<?php
// This prints out all hidden setting fields
settings_fields( 'my_option_group' );
do_settings_sections( 'my-setting-admin' );
submit_button();
?>
</form>
</div>
<?php
}
/**
* Register and add settings
*/
public function page_init()
{
register_setting(
'my_option_group', // Option group
'my_option_name', // Option name
array( $this, 'sanitize' ) // Sanitize
);
add_settings_section(
'setting_section_id', // ID
'My Custom Settings', // Title
array( $this, 'print_section_info' ), // Callback
'my-setting-admin' // Page
);
add_settings_field(
'id_number', // ID
'ID Number', // Title
array( $this, 'id_number_callback' ), // Callback
'my-setting-admin', // Page
'setting_section_id' // Section
);
add_settings_field(
'title',
'Title',
array( $this, 'title_callback' ),
'my-setting-admin',
'setting_section_id'
);
}
/**
* Sanitize each setting field as needed
*
* @param array $input Contains all settings fields as array keys
*/
public function sanitize( $input )
{
$new_input = array();
if( isset( $input['id_number'] ) )
$new_input['id_number'] = absint( $input['id_number'] );
if( isset( $input['title'] ) )
$new_input['title'] = sanitize_text_field( $input['title'] );
return $new_input;
}
/**
* Print the Section text
*/
public function print_section_info()
{
print 'Enter your settings below:';
}
/**
* Get the settings option array and print one of its values
*/
public function id_number_callback()
{
printf(
'<input type="text" id="id_number" name="my_option_name[id_number]" value="%s" />',
isset( $this->options['id_number'] ) ? esc_attr( $this->options['id_number']) : ''
);
}
/**
* Get the settings option array and print one of its values
*/
public function title_callback()
{
printf(
'<input type="text" id="title" name="my_option_name[title]" value="%s" />',
isset( $this->options['title'] ) ? esc_attr( $this->options['title']) : ''
);
}
}
if( is_admin() )
$my_settings_page = new MySettingsPage();
If you want to add new Settings Sections, just do it and point the desired Settings Fields to the new section.
Pull the information wherever needed using: get_option( 'my_option_name' );.
