调用cakephp中的函数 [英] Calling functions in cakephp

问题描述

public function data()
{ 
if($old != $status || $prev_lat != $lat || $prev_long != $long)
            {
                if($status == 'Village' || 'Unknown')
                {
                    exec_query();
                }
                else if($status == 'Town' || 'City')
                {
                    exec_query();
                }   
            }
}


public function exec_query()
{
    //Some data;
}

但是每当我调用这个函数时，

But whenever i call this function i get error like:-

Call to undefined function exec_query() 

任何人都可以告诉我hw在cakephp中调用函数

Can anyone tell me hw to call a function in cakephp

推荐答案

添加 $ this-> 之前的函数名称：

public function data()
{ 
if($old != $status || $prev_lat != $lat || $prev_long != $long)
            {
                if($status == 'Village' || 'Unknown')
                {
                    $this->exec_query();
                }
                else if($status == 'Town' || 'City')
                {
                    $this->exec_query();
                }   
            }
}


public function exec_query()
{
    //Some data;
}
