WordPress WP_Customize_Image_Control()无法使用icon(.ico)文件 _WordPress主题

我在主题定制器中添加了一个图片控件来更改收藏夹图标。问题是我无法上传.ico文件。它可以与其他文件格式(.jpg, .png)配合使用。现在, 我正在使用WP_Customize_Upload_Control()更改收藏夹图标。我想知道有什么方法可以使用WP_Customize_Image_Control()上传.ico文件。在Codex中没有此类的文档。
提前致谢
#1我的解决方案是扩展WP_Customize_Image_Control类以能够接受.ico文件。为此, 请使用以下代码创建一个名为” customize-favicon.php” 的新文件：

< ?php class SO_Customize_Favicon_Control extends WP_Customize_Image_Control { public function __construct( $manager, $id, $args ) {$this-> extensions[] = 'ico'; return parent::__construct( $manager, $id, $args ); } } ?>

然后, 在你的custom_register回调函数中, 在新文件中添加一个include, 并将标准图像控件类替换为刚创建的类：

include 'customize-favicon.php'; $wp_manager-> add_control( new Custom_Customize_Favicon_Control( $wp_manager, 'favicon_image', array( 'label'=> 'Favicon Image (16x16 px or 32x32 px)', 'section' => 'some_global_section', 'settings'=> 'favicon_image', 'priority' => 1, ) ) );

#2我必须使用几个过滤器来允许WP Media Library中的.ico MIME类型。然后, 我为Favicon上传创建了一个自定义设置处理程序和控件。
【WordPress WP_Customize_Image_Control()无法使用icon(.ico)文件】在媒体库中允许.ico

add_filter( 'getimagesize_mimes_to_exts', array($this, 'add_ico_mime'), 99999 ); add_filter( 'upload_mimes', array($this, 'add_ico_ext'), 99999 ); /*Add Ico Mime Type to Allowed Extension*/ public function add_ico_mime( $mime ) { $mime[ 'image/vnd.microsoft.icon' ] = "ico"; $mime[ 'image/x-icon' ]= "ico"; $mime[ 'image/ico' ]= "ico"; return $mime; }/*Add Ico File Extension to Allowed Mimes*/ public function add_ico_ext( $site_mimes ) { if (isset($site_mimes['ico']) === false) $site_mimes['ico'] = 'image/vnd.microsoft.icon'; return $site_mimes; }

设置处理程序

/*Setup WP Customizer Options*/ public $transport = 'refresh'; // 'PostMessage'; public $option_type = 'theme_mod'; /*Handle Uploader Settings*/ public function add_favicon_control($setting_id, $section_id, $label = '', $priority = 0) { global $wp_customize, $theme_namespace; $setting_args = array( 'type'=> $this-> option_type, 'capability'=> 'edit_theme_options', 'transport'=> $this-> transport, 'sanitize_callback' => 'esc_url_raw', ); $wp_customize-> add_setting( $setting_id, $setting_args ); $favicon_control = new Favicon_Control( $wp_customize, $setting_id, array( 'label'=> __( $label, $theme_namespace ), 'section'=> "ds_theme_{$section_id}_section_id", 'priority'=> $priority, 'settings'=> $setting_id, 'context'=> 'favicon' ) ); $wp_customize-> add_control( $favicon_control ); return $favicon_control; }

声明自定义图标控件

/*Custom Favicon Control Class*/ class Favicon_Control extends WP_Customize_Image_Control { public $setting_id; public function __construct( $manager, $id, $args = array() ) { $this-> extensions[] = 'ico'; $this-> setting_id = $id; parent::__construct( $manager, $id, $args ); }public function tab_uploaded() { $my_context_uploads = get_posts( array( 'post_type'=> 'attachment', 'meta_key'=> '_wp_attachment_context', 'meta_value' => $this-> context, 'orderby'=> 'post_date', 'nopaging'=> true, ) ); ?> < div class="uploaded-target"> < /div> < ?php if ( empty( $my_context_uploads ) ) return; ?> < div class="uploaded-favicons" data-controller="< ?php esc_attr_e( $this-> setting_id ); ?> "> < ?php foreach ( (array) $my_context_uploads as $my_context_upload ) { $this-> print_tab_image( esc_url_raw( $my_context_upload-> guid ) ); } ?> < /div> < ?php } }

最后, 初始化处理程序
