近期在看YII
public $template='{view} {update} {delete}';
以上这种写法,如何单独输出{view},{update}呢
同时以下代码片段还会报错
foreach(array('view','update','delete') as $id) { $button=array( 'label'=>$this->{$id.'ButtonLabel'}, 'url'=>$this->{$id.'ButtonUrl'}, 'imageUrl'=>$this->{$id.'ButtonImageUrl'}, 'options'=>$this->{$id.'ButtonOptions'}, ); if(isset($this->buttons[$id])) $this->buttons[$id]=array_merge($button,$this->buttons[$id]); else $this->buttons[$id]=$button; }
报错提示:Fatal error: Using $this when not in object context in D:\Wamp\Apache\htdocs\1.01\this.php on line 9

public $template='{view} {update} ';
不久可以单独输出view和update了么?
<?php $template='{view} {update} {delete}'; echo $template; ?>
output:
{view} {update} {delete}
<?php $template='{view} {update} {delete}'; echo $template; ?>
output:
{view} {update} {delete}
view ,update,delete 分别对应yii grid中的查看按钮,更新按钮和删除按钮组件,需要哪个就加哪个。
比如,只需要view按钮:
$template='{view}';
这个我也知道的,我想知道如何单独输出view,update啊

You should care about DependencyInjection(DI) because it makes your code clearer and easier to maintain. 1) DI makes it more modular by decoupling classes, 2) improves the convenience of testing and code flexibility, 3) Use DI containers to manage complex dependencies, but pay attention to performance impact and circular dependencies, 4) The best practice is to rely on abstract interfaces to achieve loose coupling.

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.
