错误:当我试图保存在设置页面中所做的更改时，找不到选项页

Question

我在开发一个插件。一切都很好但突然间当我试图保存插件设置..。我发现的错误是页面选项没有找到。

我在找答案，但没有一个能弥补我的错误.下面是一些生成设置页面并将选项保存在数据库中的代码：

admin.php

 *
 * @link    https://webstower.com.ar/wtdomcheck
 * @since   1.0.0
 *
 **/

require_once WTDOMCHECK_PLUGIN_DIR.'admin/class/class-admin.php';

$wtdomadmin = '';

//All the magic is done here!
if ( class_exists('admin') ) {
    
    $wtdomadmin = new admin();
    $wtdomadmin->WTRegister();

}
?>

class_admin.php

function __construct() 
    {

        //Instantiate the API that will construct our admin pages
        $this->settings = new ApiWpadmin();

        //Array of pages to create
        $this->pages = [
            [
                'page_title' => 'My plugin settings page', 
                'menu_title' => 'Settings page', 
                'capability' => 'manage_options', 
                'menu_slug'  => 'wtdomaincheck', 
                'callback'   => array($this, 'WTLoadSettingTemplate'), 
                'icon_url'   => 'dashicons-admin-generic', 
                'position'   => 117
            ]
        ];
        
    
        //Register the settings in the database
        add_action('admin_init', array($this, 'WTSaveSettings'));
    }



    //
    // PARAM
    // Register all the actions & filters for wp-admin
    //
    public function WTRegister() 
    {

        $this->settings->
            WTAddPages( $this->pages ) ->
            WTWithSubPage( 'Dashboard' ) ->
            WTAddSubPages( $this->subpages ) ->
            WTRegister();

    }


    //
    // PARAM
    // Register the settings values in the database
    //
    public function WTSaveSettings()
    {
            $wt_options = array (
                'display-on-free'       => $_POST['display-on-free'],
                'display-on-registered' => $_POST['display-on-registered'],
                'display-on-invalid'    => $_POST['display-on-invalid'],
                'before-whois-output'   => $_POST['before-whois-output'],
                'after-whois-output'    => $_POST['after-whois-output'],
                'callurl'               => $_POST['callurl'],
                'varname'               => $_POST['varname'],
                'resp-free-domain'      => $_POST['resp-free-domain'],
                'resp-registered-domain'=> $_POST['resp-registered-domain'],
                'resp-invalid-domain'   => $_POST['resp-invalid-domain'],
                'custom-css'            => $_POST['custom-css'],
                'license-key'           => $_POST['license-key'],
                'style-box-bgcolor'     => $_POST['style-box-bgcolor'],
                'style-www-color'       => $_POST['style-www-color'],
                'style-button-color'    => $_POST['style-button-color'],
                'style-button-bgcolor'  => $_POST['style-button-bgcolor'],
                'style-result-color'    => $_POST['style-result-color'],
                'style-result-bgcolor'  => $_POST['style-result-bgcolor']
            );

            if (isset($_POST['enable-multiple-search'])) 
                $wt_options[] = array('enable-multiple-search' => $_POST['enable-multiple-search'] );

            if (isset($_POST['show-www'])) 
                $wt_options[] = array('show-www' => $_POST['show-www'] );

            if (isset($_POST['show-whois-output'])) 
                $wt_options[] = array('show-whois-output' => $_POST['show-whois-output'] );

            update_option( 'wtdomaincheck', $wt_options );
    }



    //
    // PARAM
    // Loads the template that shows the settings page
    //
    public function WTLoadSettingTemplate()
    {
        
        require_once WTDOMCHECK_PLUGIN_DIR.'admin/html/settings.php';
    }

?>

setings.php

                    WTBuildPillTabs($sections);
                    ?>
                
            

            
                
                    WTBuildPillPanes($sections);
                    ?>

当我安装插件时，选项记录将在wp_options表中创建。将显示“设置”页。但当我试图保存这些变化时..。未找到的选项页出现在屏幕上。

任何帮助都将不胜感激。

Answer 1

问题在我的文件settings.php (它呈现表单)中。看表格动作。它说action="options.php"，然后settings_field()用正确的操作插入一个隐藏字段。但是WordPress优先处理表单操作，所以当提交表单时，WordPress尝试加载options.php，而不是在隐藏字段中加载正确的操作。

解决方案是什么？简单：

在表单action="options.php"中用action=""替换。

这个简单的补丁修复了错误。
