我有一系列行为$actas。问题是当我在数组字符串上添加 date() 函数时,它返回一个错误:
例:
public $actas = array(
'Uploader.Attachment'=>array(
'books' => array(
'maxWidth' => 1200,
'maxHeight' => 1200,
'extension' => array('pdf'),
'nameCallback' => '',
'append' => '',
'prepend' => '',
'tempDir' => TMP,
'uploadDir' => '/var/www/html/apps/webroot/files/uploads/books' . date('d-m-Y'),//this is where I want to add the function.
'transportDir' => ''
)
)
);
但是它不起作用。我也喜欢这个:
public $actas = array(
'Uploader.Attachment'=>array(
'books' => array(
'maxWidth' => 1200,
'maxHeight' => 1200,
'extension' => array('pdf'),
'nameCallback' => '',
'append' => '',
'prepend' => '',
'tempDir' => TMP,
'uploadDir' => "/var/www/html/apps/webroot/files/uploads/books'".date('d-m-Y')."'",//this is where I want to add the function.
'transportDir' => ''
)
)
);
也没有工作。
所以我的问题是如何做到这一点?如果我有很多错误,请告诉我,以便我了解更多有关此事的信息。
提前谢谢。
这是Post.php模型的完整源代码

啊,
好吧,我没有戴着OO帽子看它。 您不能这样做,因为:
Properties
类成员变量称为"属性"。您可能还会看到它们 指使用其他术语,例如"属性"或"字段",但 出于此参考的目的,我们将使用"属性"。他们是 通过使用关键字之一定义 公共、受保护 或 私有, 后跟一个正态变量声明。本声明可以 包括初始化,但此初始化必须是 常量值 - 也就是说,它必须能够在编译时进行评估 时间,并且不得依赖于运行时信息才能 评价。
您需要使用 __construct()
