How to retrieve form data?

我想保存输入数据的值并检索它。我刚开始创建WordPress插件，但我不知道如何从表单中获取值。我看过一些插件开发教程，但我无法正确开发它。这是我的代码：

/*
Plugin Name:  My Custorm Form
Plugin URI:   https://abcd.com
Description:  New plugin
Version:      0.1
Author:       RB
*/

function my_plugin_settings()
{
    add_menu_page( \'My Plugin\',
                    \'myCust Form\',
                    \'administrator\',
                    \'insert-my-plugin_bro\',
                    \'my_plugin_settings_page\',
                    \'dashicons-translation\',
                    \'60\'
                );  
}
add_action(\'admin_menu\', \'my_plugin_settings\');


function my_plugin_options()
{
    register_setting(\'my-form-group\',\'user_input_name\');
}
add_action(\'admin_init\', \'my_plugin_options\');


function my_plugin_settings_page()
{
    echo "<h1>My Plugin Settings</h1>";
    ?>
    <div class="wrap">
        <form  action="options.php" method="post">
        <?php settings_fields(\'my-form-group\'); ?>
            <b>Enter a name to display:</b><br/>
            <input type="text" name="default-image-url" value="" >

            <?php submit_button(); ?>
        </form>
    </div>
    <?php
}
?>

<?php add_action(\'admin_menu\', \'my_plugin_create_menu\'); function my_plugin_create_menu() { //create new top-level menu add_menu_page( \'My Plugin\', \'myCust Form\', \'administrator\', \'insert-my-plugin_bro\', \'my_plugin_settings_page\', \'dashicons-translation\', \'60\' ); //call register settings function add_action( \'admin_init\', \'register_my_plugin_settings\' ); } function register_my_plugin_settings() { //register our settings register_setting( \'my-plugin-settings-group\', \'display_name\' ); } function my_plugin_settings_page() { ?> <div class="wrap"> <h1>My Plugin Settings</h1> <form method="post" action="options.php"> <?php settings_fields( \'my-plugin-settings-group\' ); ?> <?php do_settings_sections( \'my-plugin-settings-group\' ); ?> <table class="form-table"> <tr valign="top"> <th scope="row">Enter a name to display</th> <td><input type="text" name="display_name" value="<?php echo esc_attr( get_option(\'display_name\') ); ?>" /></td> </tr> </table> <?php submit_button(); ?> </form> </div> <?php } ?>

Link Forms on Wordpress

在我们的Wordpress网站上，我们有一个由一系列（单选按钮式）问题组成的表单。根据用户对特定问题的回答，我们希望向用户显示不同的表单。也就是说，我们希望将多个表单链接到一个主表单。这可能吗？如果是这样的话，有人能解释一下如何做到这一点，或者给我指一些可能有用的资源吗？我对Wordpress很陌生。
