ThinkPHP study notes ThinkPHP paging and the use of verification code

CommonAction

[php]

/**

in ThinkPHP

* Just let other Actions inherit the current CommonAction

class CommonAction extends Action{

public function verify(){

//Import verification code class

//Method 1:

import('ORG.Util.Image');

//Method 2: @ represents the lib folder of the current project (you need to copy it yourself or write a new class yourself)

// import('@.ORG.Image')

// Image::buildImageVerify();

//Extended modifications

/**

* @param string $length digits

* @param string $mode Type (0 letters, 1 number, 2 uppercase letters, 3 lowercase letters, 4 Chinese, 5 mixed)

* @param string $type image format

* @param string $width width

* @param string $height Height

* buildImageVerify($length=4,$mode=1,$type='png',$width=48,$height=22,$verifyName='verify')

Image::buildImageVerify(5,5,'png',80,22);

//Chinese verification code (2.0 will have a problem: msubstr has an error)

//1. Modify function::msubstr

//2. Adding font ttf needs to be placed under the same level directory as image

//Extensions can be viewed in the class file

// Image::GBVerify();

}

/**

in ThinkPHP

class PageAction extends CommonAction{

public function index(){

//Import page

import('ORG.Util.Page');

$user=M('User');

$count=$user->count();

$page=new Page($count, 3);

//Modify prompt information

$page->setConfig('header', "member");

$page->setConfig('prev', "previous group");

$page->setConfig('next', "next group");

$page->setConfig('first', "Homepage");

$page->setConfig('last', "last page");

//Define theme style (see documentation)

// $page->setConfig('theme', '

');

$show=$page->show();

$list=$user->order('id desc')->limit($page->firstRow.','.$page->listRows)->select();

$this->assign('title','page demo');

$this->assign('alist',$list);

$this->assign('page',$show);
