This is not an attribute. It is a method. It is not defined before.

class Java_Pagination{    protected $_total = 0;    protected $_total_page = 0;    protected $_page = 1;    protected $_page_size = 10;    protected $_link = '';    protected $_grep = 3;     protected $_admin = false;    protected $_css_next = 'next-page';    protected $_css_prev = 'prev-page';    protected $_css_curr = 'curr-page';    protected $_css_page = 'page-nav inline-block';     public function __construct ( $page, $page_size, $total, $admin = false )    {        $this->set_current_page( $page );        $this->set_page_size( $page_size );        $this->set_total( $total );         if ( $admin )        {            $this->_admin = $admin;        }        //$this->_link = $_SERVER['REQUEST_URI'];        $this->set_link( $_SERVER['REQUEST_URI'] );    }    }

There are two possibilities:

1. You didn't fully understand the code. The class method is available below;

2. Does this class inherit other classes, namely:

class Java_Pagination extends SomeClass{    //your code...}

Is this class not inherited?

Set_current_page

This seems to be a database operation in ThinkPHP.

One possibility is that subclass implementation is required.

Your code should not be fully-viewed, there are inherited classes, or there are implementation methods below. In this case, php will report its own errors.
