错误“函数的参数太少"； [英] Error "Too few arguments to function"

问题描述

我在以下代码段中出错:函数showtbl :: GetTabellen_ns()的参数太少，第153行的abcde/folder/php.php中传递了0，而恰好是2个期望

I got an error in the following code piece: Too few arguments to function showtbl::GetTabellen_ns(), 0 passed in abcde/folder/php.php on line 153 and exactly 2 expected

不知道我为什么得到这个.我对PHP Prado和所有编程语言都是新手，所以也许是一个愚蠢的错误.

Don't know why I get this. I'm quite new to PHP Prado and in all programming so maybe a stupid mistake.

protected function GetTabellen_ns($offset, $limit) 
{
    $criteria=new TActiveRecordCriteria;
    $criteria->Condition = 'name = $name';
    $criteria->OrdersBy['name'] = 'asc';
    $criteria->Limit = 15;
    $criteria->Offset = 20;

    return prdtblRecord::finder()->findAll($criteria);           
}

protected function populateData_ns($offset, $limit) 
{
    $offset=$this->Repeater->CurrentPageIndex*$this->Repeater->PageSize;
    $limit=$this->Repeater->PageSize;
    if($offset+$limit>$this->Repeater->VirtualItemCount) {
        $limit=$this->Repeater->VirtualItemCount-$offset;
    }
    $this->Repeater->DataSource=$this->GetTabellen_ns($offset,$limit);
    $this->Repeater->dataBind();
}

寻求帮助，希望有人能帮助我.

Thx for help hope someone can help me.

如果有人可以告诉我$ offset和$ limit的设置也将对我有很大帮助.

edit: If someone can tell me how $offset and $limit get set would help me alot too.

推荐答案

您可以这样调用函数: $ this-> GetTabellen_ns()

You call the function like this: $this->GetTabellen_ns()

但是函数需要两个参数( offset 和 limit ).

But function needs two arguments (offset and limit).

如果要将这些参数设置为可选参数，则可以给它们一个默认值，如下所示:

If you want to set these argument as optional argument, you can give them a default value like this:

protected function GetTabellen_ns($offset = 0, $limit = 0){
 .

 .
}
