最好的方法是添加Meta Box 添加/编辑页面仪表板。

然后，在将脚本排队时，可以检查该帖子的元数据，如果设置了元数据，则将脚本排队。

注意：这里有很多活动部件。我会把它分解成可消化的小块。

示例代码。注意-您需要在函数中插入。php，并根据您的特定主题进行调整：

First, let\'s get the metabox registered to show up

function slider_script_add_meta_box() {
    add_meta_box(
        \'do_script_sectionid\',
        \'Include Slider Script\',
        \'slider_script_meta_box\',
        \'page\'
    );
}

add_action( \'add_meta_boxes\', \'slider_script_add_meta_box\' );

Now, let\'s display the metabox option

function slider_script_meta_box( $post ) {
    // Add an nonce field so we can check for it later.
    wp_nonce_field( \'slider_script_action_name\', \'slider_script_meta_box_nonce\' );
    // Get existing value if set
    $value = get_post_meta( $post->ID, \'_do_slider_script\', true );
    $checked = ($value) ? \' checked\' : \'\';
    echo \'<label for="myplugin_new_field">\';
    echo \'Include Slider Script:\';
    echo \'</label> \';
    echo \'<input type="checkbox" id="do_slider_script" name="do_slider_script"\' . $checked . \' />\';
} 

Next, hook the page save to ensure the data gets saved

function myplugin_save_meta_box_data( $post_id ) {
    // Check if our nonce is set and verifies.
    if ( ! isset( $_POST[\'slider_script_meta_box_nonce\'] ) || ! wp_verify_nonce( $_POST[\'slider_script_meta_box_nonce\'], \'slider_script_action_name\' ) ) {
        return;
    }

    // If this is an autosave, our form has not been submitted, so we don\'t want to do anything.
    if ( defined( \'DOING_AUTOSAVE\' ) && DOING_AUTOSAVE ) {
            return;
    }

    // Check the user\'s permissions.
    if ( isset( $_POST[\'post_type\'] ) && \'page\' == $_POST[\'post_type\'] ) {
        if ( ! current_user_can( \'edit_page\', $post_id ) ) {
            return;
        }
    }

    // Finally! Safe for us to save the data now.
    // Sanitize user input.
    $do_script = (isset($_POST[\'do_slider_script\'])) ? 1 : 0;
    // Update the meta field in the database.
    update_post_meta( $post_id, \'_do_slider_script\', $do_script );
}

add_action( \'save_post\', \'myplugin_save_meta_box_data\' );

FINALLY, add this section to actually register / enqueue your script on the relevant pages

function enqueue_slider_scripts() {
    global $post;
    $do_script = get_post_meta($post->ID, \'_do_slider_script\', true);
    if ($do_script) {
        // Alter the path to your script as needed
        wp_enqueue_script(\'slider_script\', get_template_directory_uri() . \'/js/example.js\');
    }
}

add_action( \'wp_enqueue_scripts\', \'enqueue_slider_scripts\' );

Again, 所有这些都可以粘贴到函数中。php文件。或者，一种更有条理的方法是在主题文件夹中创建一个新的php文件，并将其包含到函数文件中。这将允许您为文件指定一个有意义的名称，并将代码“组织”到相关的组中。
