我正在创建自定义主题选项，我收到了这个PHP错误：警告：字符串偏移量非法。。。在线75

// adding the page to menu
add_menu_page(\'Theme Options\', \'Theme Options\', \'manage_options\', \'rm-options\', \'rm_display_options_page\');

// form to display options
<form method="post" action="options.php">
            <?php
                settings_fields(\'rm_theme_options\'); // options name
                do_settings_sections(\'rm-options\'); // page
                submit_button();
            ?>
</form>

// adding a section
add_settings_section(\'rm_general_section\', \'General options\', \'rm_general_section_callback\', \'rm-options\');

// register the options
register_setting( \'rm_theme_options\', \'rm_theme_options\', \'esc_attr\' );

// register a field
$some_option_args = array(\'type\' => \'text\', \'id\' => \'some_option_name\', \'name\' => \'some_option_name\', \'desc\' => \'Description\');
add_settings_field(\'some_option_name\', \'Some Option\', \'pu_display_setting\', \'rm-options\', \'rm_general_section\', $some_option_args);

// finally a function to display the fields
function pu_display_setting($args){
    extract( $args );
    $options = get_option( \'rm_theme_options\' );

    switch ( $type ) {  
          case \'text\':
              //$options[$id] = stripslashes($options[$id]);  
              //$options[$id] = esc_attr( $options[$id]);
              // this is line 75 where im getting the warning
              echo "<input type=\'text\' id=\'$id\' name=\'" . \'rm_theme_options\' . "[$id]\' value=\'$options[$id]\'>";
              echo ($desc != \'\') ? "<br /><span class=\'description\'>$desc</span>" : "";  
          break;  
    }
}

现在，当我试图保存选项时，错误仍然存在，输入的值是“A”，当我检查数据库时，实际值只是“Array”。75号线怎么了？在我获得显示设置功能的教程中，还有另外两行正在剥离slahes和esc\\u attr。

编辑：

现在我的代码就是这样的，我用这个函数来显示页面，但我不想把每一段代码都放在这里，这样就不会太乱了。这就是它的完整性：

function rm_display_options_page() { ?>
    <div class="wrap">
        <h2><?php echo \'Theme options: \' . wp_get_theme(); ?></h2>
        <div class="description">Theme options description</div>

        <?php settings_errors(); ?>

        <form method="post" action="options.php">
            <?php
                settings_fields(\'rm_theme_options\'); // options name
                do_settings_sections(\'rm-options\'); // page
                submit_button();
            ?>
        </form>
    </div>
<?php
}

第75行是：

echo "<input type=\'text\' id=\'$id\' name=\'" . \'rm_theme_options\' . "[$id]\' value=\'$options[$id]\'>";

// adding the page to menu
add_menu_page(\'Theme Options\', \'Theme Options\', \'manage_options\', \'rm-options\', \'rm_display_options_page\');

// form to display options
<form method="post" action="options.php">
        <?php
            settings_fields(\'rm_theme_options\'); // options name
            do_settings_sections(\'rm-options\'); // page
            submit_button();
        ?>
</form>

// adding the page to menu
add_menu_page(\'Theme Options\', \'Theme Options\', \'manage_options\', \'rm-options\', \'rm_display_options_page\');

            settings_fields(\'rm_theme_options\'); // options name

            submit_button();
        ?>
