ThinkPHP where conditional paging instance with variables

This paper describes the implementation method of where conditional paging with ThinkPHP variables. Share it for your reference.

The main function codes are as follows:

$Form= D('Announcement');

import("ORG.Util.Page");

$count = $Form->count();    // Calculate the total 

$p = new Page ( $count, 5 );

$map = array();//  Use indexed arrays or objects as query conditions , The conditional effects of using object mode and array mode are the same and interchangeable. 

$map['user_id']=$_SESSION['loginUserId'];  //

$list=$Form->limit($p->firstRow.','.$p->listRows)->order('announcement_id desc')->where($map)->findAll();  // Writing of paging statement   where Direct application 

//dump($Form->getLastSql()); // Print out sql Statement 

$page = $p->show ();        // Paging mapping 

I hope this article is helpful to everyone's PHP programming.
