主题化可帮助您用另一视图替换一组视图,而无需修改原始视图文件。您应该将视图应用程序组件的theme属性设置为使用主题。
您还应该定义以下属性-
yii \ base \ Theme :: $ basePath-定义CSS,JS,图像等的基本目录。
yii \ base \ Theme :: $ baseUrl-定义主题资源的基本URL。
yii \ base \ Theme :: $ pathMap-定义替换规则。
例如,如果您在UserController中调用$ this-> render(’create’) ,则将呈现@ app / views / user / create.php视图文件。但是,如果像下面的应用程序配置中那样启用主题设置,则将呈现视图文件@ app / themes / basic / user / create.php。
步骤1-以这种方式修改config / web.php文件。
'basic',
'basePath' => dirname(__DIR__),
'bootstrap' => ['log'],
'components' => [
'request' => [
// !!! insert a secret key in the following (if it is empty) - this
//is required by cookie validation
'cookieValidationKey' => 'ymoaYrebZHa8gURuolioHGlK8fLXCKjO',
],
'cache' => [
'class' => 'yii\caching\FileCache',
],
'user' => [
'identityClass' => 'app\models\User',
'enableAutoLogin' => true,
],
'errorHandler' => [
'errorAction' => 'site/error',
],
'mailer' => [
'class' => 'yii\swiftmailer\Mailer',
// send all mails to a file by default. You have to set
// 'useFileTransport' to false and configure a transport
// for the mailer to send real emails.
'useFileTransport' => true,
],
'log' => [
'traceLevel' => YII_DEBUG ? 3 : 0,
'targets' => [
[
'class' => 'yii\log\FileTarget',
'levels' => ['error', 'warning'],
],
],
],
'view' => [
'theme' => [
'basePath' => '@app/themes/basic',
'baseUrl' => '@web/themes/basic',
'pathMap' => [
'@app/views' => '@app/themes/basic',
],
],
],
'db' => require(__DIR__ . '/db.php'),
],
'modules' => [
'hello' => [
'class' => 'app\modules\hello\Hello',
],
],
'params' => $params,
];
if (YII_ENV_DEV) {
// configuration adjustments for 'dev' environment
$config['bootstrap'][] = 'debug';
$config['modules']['debug'] = [
'class' => 'yii\debug\Module',
];
$config['bootstrap'][] = 'gii';
$config['modules']['gii'] = [
'class' => 'yii\gii\Module',
];
}
return $config;
?>
我们添加了视图应用程序组件。
步骤2-现在创建web / themes / basic目录结构和theme / basic / site 。在主题/基本/站点文件夹中,使用以下代码创建一个名为about.php的文件。
title = 'About';
$this->params['breadcrumbs'][] = $this->title;
$this->registerMetaTag(['name' => 'keywords', 'content' => 'yii, developing,
views, meta, tags']);
$this->registerMetaTag(['name' => 'description', 'content' => 'This is the
description of this page!'], 'description');
?>
= Html::encode($this->title) ?>
This is the About page. You may modify the following file to customize its content:
步骤3-现在,转到http:// localhost:8080 / index.php?r = site / about ,将呈现themes / basic / site / about.php文件,而不是views / site / about.php文件。
步骤4-对于主题模块,以这种方式配置yii \ base \ Theme :: $ pathMap属性。
'pathMap' => [
'@app/views' => '@app/themes/basic',
'@app/modules' => '@app/themes/basic/modules',
],
步骤5-对于主题小部件,以这种方式配置yii \ base \ Theme :: $ pathMap属性。
'pathMap' => [
'@app/views' => '@app/themes/basic',
'@app/widgets' => '@app/themes/basic/widgets', //
有时您需要指定一个基本主题,其中包含应用程序的基本外观。要实现此目标,可以使用主题继承。
步骤6-以这种方式修改视图应用程序组件。
'view' => [
'theme' => [
'basePath' => '@app/themes/basic',
'baseUrl' => '@web/themes/basic',
'pathMap' => [
'@app/views' => [
'@app/themes/christmas',
'@app/themes/basic',
],
]
],
],
在上述配置中, @ app / views / site / index.php视图文件的主题将为@ app / themes / christmas / site / index.php或@ app / themes / basic / site / index.php,具体取决于在哪个文件上。如果两个文件都存在,则将使用第一个文件。
步骤7-创建themes / christmas / site目录结构。
步骤8-现在,在themes / christmas / site文件夹内,使用以下代码创建一个名为about.php的文件。
title = 'About';
$this->params['breadcrumbs'][] = $this->title;
$this->registerMetaTag(['name' => 'keywords', 'content' => 'yii, developing,
views, meta, tags']);
$this->registerMetaTag(['name' => 'description', 'content' => 'This is the
description of this page!'], 'description');
?>
Christmas theme
This is the About page. You may modify the following file to customize its content:
步骤9-如果您访问http:// localhost:8080 / index.php?r = site / about ,您将看到使用圣诞节主题的更新后的关于页面。
