重写 CakePHP 中的验证方法

我想 ovveride CakePHP 中的默认 url() 验证方法，因为它不允许在 url 中使用 ~ 。我认为在 AppModel 中声明一个 url() 方法就足够了，但似乎核心方法相对于用户定义的方法具有优先权。

我认为（但我没有尝试过）一种可能的方法是使用

$validate = array('url' => array(
    'rule' => array('Userdefined', 'url'),
    'message' => 'This is not an URL!!!'
));

或类似的东西（正确的语法是什么？）。但这并不完全令人满意。

事实上，我将 $validate 变量作为 JSON 对象传递给我的 javascript，然后相应地进行客户端验证。基本上我已经用 JavaScript 重写了 CakePHP 验证 automagic 的一部分。所以我真的很想这样做，

$validate = array('url' => array(
    'rule' => 'url',
    'message' => 'This is not an URL!!!'
));

以免破坏客户端验证。

编辑：事实证明我错了。问题是 Validation 中的方法与 Model 中的方法的调用方式不同，因此在复制/粘贴时必须注意。

第一个区别是 $check 现在将是一个数组而不是字符串，但我已经弄清楚了。我没有意识到的是另一个参数数组被传递给模型中的验证方法。由于 url() 的签名结果

url($check, $strict = false)

是 $strict 始终具有 true 值，因此需要带有协议前缀的完整 URL。看到带有波形符的预期 URL 没有得到验证，我认为问题在于 CakePHP 仍然使用旧方法。

I want to ovveride the default url() validation method in CakePHP, since it does not allow the use of ~ inside urls. I thought it would be enough to declare a url() method in AppModel, but it seems that core methods have the precedence with respect to user defined ones.

I think (but I have not tried) one possible way would be to use

$validate = array('url' => array(
    'rule' => array('Userdefined', 'url'),
    'message' => 'This is not an URL!!!'
));

or something like that (what is the correct sintax?). But this is not completely satisfying.

Indeed I pass the $validate variable as a JSON object to my javascript, and then I do client validation accordingly. Basically I have rewritten part of the CakePHP validation automagic in javascript. So I really want to have

$validate = array('url' => array(
    'rule' => 'url',
    'message' => 'This is not an URL!!!'
));

in order not to break client-side validation.

EDIT: It turns out I were wrong. The problem is that methods in Validation are called differently from methods in Model, so one has to pay attention when copying/pasting.

The first difference is that $check will now be an array instead of a string, but this I already figured out. What I did not realize is that another array of parameters is passed to Validation methods in Model. Since the signature of url() was

url($check, $strict = false)

the result was that $strict always had the value true, thereby requiring full URLs with protocol prefix. Seeing that the intended URL with tilde was not validating I assumed that the problem was that CakePHP still used the old method.
