项目需求：
1.添加多套style文件不定期 切换风格
2.后台方便切换管理
插件实现
步骤1.
在当前的主题文件下找到functions.php文件 没有的话自己写一个
copy如下代码到文件
$themename = "My theme";
$shortname = "MT";
$options = array (
array( "name" => "Style Sheet",
"desc" => "Enter the Style Sheet you would like to use for Sweet Ass Theme",
"id" => $shortname."_style_sheet",
"type" => "select",
"options" => array("default", "green", "blue", "yellow"),
"std" => "default"),
);
//presentation//
function mytheme_add_admin() {
global $themename, $shortname, $options;
if ( $_GET['page'] == basename(__FILE__) ) {
if ( 'save' == $_REQUEST['action'] ) {
foreach ($options as $value) {
update_option( $value['id'], $_REQUEST[ $value['id'] ] ); }
foreach ($options as $value) {
if( isset( $_REQUEST[ $value['id'] ] ) ) { update_option( $value['id'], $_REQUEST[ $value['id'] ] ); } else { delete_option( $value['id'] ); } }
header("Location: themes.php?page=functions.php&saved=true");
die;
} else if( 'reset' == $_REQUEST['action'] ) {
foreach ($options as $value) {
delete_option( $value['id'] ); }
header("Location: themes.php?page=functions.php&reset=true");
die;
}
}
add_theme_page($themename." Options", "".$themename." Options", 'edit_themes', basename(__FILE__), 'mytheme_admin');
}
function mytheme_admin() {
global $themename, $shortname, $options;
if ( $_REQUEST['saved'] ) echo ''.$themename.' settings saved.
';
if ( $_REQUEST['reset'] ) echo ''.$themename.' settings reset.
';
?>
Settings
