问题描述

使用与特质函数同名的PHP类

请参阅上面我刚才问的问题.这是我的原始代码.

Refer to the question I just asked above here. Here was my original code.

trait sampletrait{
   function hello(){
      echo "hello from trait";
   }
}

class client{
   use sampletrait;

   function hello(){
      echo "hello from class";
      //From within here, how do I call traits hello() function also?
   }
}

由于问题的答案,我可以像这样调用trait函数.

I can call the trait function like this thanks to the answer to the question.

class client{
   use sampletrait {
       hello as protected sampletrait_hello;
   }

   function hello(){
      $this->sampletrait_hello();
      echo "hello from class";
   }
}

我的问题是我的类客户端是否没有函数hello()但想调用它吗?

My question is if my class client did not have a function hello() but wanted to call it is this possible?

例如...

trait sampletrait{
   function hello(){
      echo "hello from trait";
   }
}

class client{
   use sampletrait {
      hello as protected sampletrait_hello;
   }
}

我知道我可以简单地说出use sampletrait;它将具有功能,但是在我的用例中,我也无法做到这一点.如果在类中不存在别名,是否可以使用别名但仍使用默认特征名称?

I'm aware that I could just simply say use sampletrait; and it would have the function but in my use case I can't do that either. Is it possible to have the aliased name but still use the trait name default if it does not exist in the class?

我的确切用例涉及PHP-ActiveRecord

My exact use case involves PHP-ActiveRecord

我有一个称为uniquecheck的特征

I have a trait called uniquecheck

trait uniquecheck {

    //@JA - Used temporarely to determine if editing for the unique checker
    static $isEditing = false;

    //@JA - This is used by PHPActiveRecord to trigger events before validation on update calls only.
    static $before_validation_on_update = array('before_validation_on_update_callback');

    //@JA - This is function used as callback from PHPActiveRecord
    public function before_validation_on_update_callback(){
        self::$isEditing = true; //@JA - Requires Uniquecheck trait to work
    }

    //@JA - This function can do single and multi-unique checks.
    //@JA - This is programmed to be replaced at a later date when validates_uniqueness_of is fixed (http://www.phpactiverecord.org/projects/main/wiki/Validations#validates_uniqueness_of)
    //@JA - EXAMPLES
    //SINGLE    -- array('name','message' => 'Can't do this')
    //MULTIPLE  -- array( array('name1','name2'), 'message' => 'can't do this and that together')
    //@JA - To be clear multiple does not mean 2 different uniques but a unique on 2 columns.  Just use this function twice for 2 separate unique checks.
    public function uniquecheck($rules = array()) {

        $classname = get_class($this);

        //@JA - Basic validation to confirm assumptions for function properties
        if(count($rules)<=0){
            die('uniquecheck.php -> Property array can not be empty');
        }

        //@JA - If its an array use the MULTIPLE method
        if(is_array($rules[0])){
            //@JA - First create the condition string
            $conditionstring = '';
            $conditionarray = array();

            $uniques = $rules[0];
            foreach($uniques as $unique){
                $conditionstring .= "$unique = ? AND ";
            }
            $conditionstring = substr($conditionstring, 0, -5);

            //@JA - Then generate the array we will use for the conditions
            $conditionarray['conditions'][] = $conditionstring;
            foreach($uniques as $unique){
                $conditionarray['conditions'][] = $this->read_attribute($unique);
            }

            $results = $classname::find('all',$conditionarray);

            if($classname::$isEditing == true){
                die('was editing');
            }else{
                die('was creating');
            }

            //@JA - If in edit mode, if the values are exactly the same as it was before then ignore this check.
            if (count($results)>=1) {
                foreach($uniques as $unique){
                    $this->errors->add($unique, $rules['message']);
                }
            }

        }else{ //@JA - Otherwise use the SINGLE method
            $unique = $rules[0];
            $results = $classname::find('all',array('conditions' => array("$unique = ?", $this->read_attribute($unique))));

            //@JA - If there is more then 1 result then its not unique!
            if (count($results)>=1) {
                $this->errors->add($unique, $rules['message']);
            }
        }
    }
}

我正在尝试使用它来解决phpactiverecords独特的检查错误,因为它不适用于我正在从事的项目的系统.

I am trying to use this to get around phpactiverecords unique check bug since it does not work in there system for a project I'm working on.

它使用这样的回调(before_validation_on_update_callback),在该回调中必须具有该名称.

It uses a callback like this (before_validation_on_update_callback), where it has to have that name.

我想使用特征将其包含在我的所有模型中,以便轻松地进行唯一检查.

I wanted to use a trait to include it in all my models for unique checking easily.

请参考此内容( http://www.phpactiverecord.org/projects/main /wiki/Callbacks )

推荐答案

尝试在trait函数上设置public,然后在重命名时受保护

Try setting public on the trait function and then protected when you rename

trait sampletrait{
   public function hello(){
      echo "hello from trait";
   }
}

class client{
   use sampletrait {
      hello as protected sampletrait_hello;
   }
}

$c = new client();
$c->hello();

如此处所说使用与以下名称相同的PHP类特性功能 hello和sampletrait_hello都将存在,但是由于hello是公共的,并且sampletrait_hello受保护,只有hello可以从外部范围调用.

As said here PHP Class Using Same Name as Trait Function both hello and sampletrait_hello will exist, but as hello is public and sampletrait_hello protected only hello will be callable from an outer scope.

如果您覆盖了hello,则可以在其中调用sampletrait_hello.

And if you overwrite hello, you will be able to call sampletrait_hello inside it.

这篇关于使用具有相同名称但可选的特征功能的文章就介绍到这了,希望我们推荐的答案对大家有所帮助,也希望大家多多支持!
