1-----Create a Controller

2-----Access View page

3-----Register variable to view page

4-----Get form data

Create a controller under the home module

Example: Table of Contents tp/application/home/controller Create TestController.class.php

Access the controller localhost/i/tp/home/test/how to do it

　　　　

<? phpnamespace Home\controller;  Use Think\controller; class extends Controller {        publicfunction  Test () {        echo "hello!" ;    }      // access the method hello   
Http://localhost/i/tp/index.php/Home/Test/test}

Two-way access method Display View page

--In the View folder under the Home module

--Create A view page in this folder just like the controller name in the new folder

For example:

--if there is a TestController.class.php Controller under the Home/controller folder, and the controller has a Ceshi method, The Ceshi () method in the TestController class under the test controller

The--ceshi method has $this->show (); Access the view page for this method corresponding to the view folder for the controller

--Then create the T-est folder under the home/view folder and create the View page ceshi.html

--This page is accessed by: localhost/i/tp/index.php/home/test/ceshi Home module Test (testcontroller.class,php) Ceshi () method under the TestController class of the Controller

<? phpnamespace Home\controller;  Use Think\controller; class extends Controller {    publicfunction  Ceshi () {        $thisShow ();    }}

Three registered variables to the view page

①--method in TP frame:

--The Controller's method registers the variable $this->assign ("Variable name", "Variable Value");　　　

such as: $this->assign (' uname ',' Zhang San ');

--View page access method {$ variable name} curly braces inside write $ symbol with variable name, cannot have space line wrapping etc.

such as: {$uname}　　

②--If the registered variable is an array, get the method: {$arr [' 0 ']} or {$arr [' id ']}

③--Loop Output

--<foreach> label , TP-specific cyclic output

--The value ofname is the variable name (consistent with the variable name in the method), and the value ofitem is the value of the obtained array (custom named)

--Register an array

     Public function Test () {        $arr=array          ("Code" = "n001", "name" and "=" Han "),          array(" Code "=" n002 "," name "=" Heavenly Clan ")        );         $this->assign ("Nation",$arr);         $this-Show ();    }

--Front-end access

 <Select>       <foreachname= "Nation"Item= "V">            <optionvalue= ' {$v. code} '>{$v. Name}</option>       </foreach> </Select>

④--if judgment

--<if> tags and else tags , TP-specific front-end judgment

The value of the condition attribute in the--<if> tag is the judging condition ,

--The variable name in the judging condition must have the $ character prefix, for example a registered variable name is an ID, the value is 0, then the ID should be condition= "$id ==0"

For example, registering variables in the test method $this->assign ("DC", 0);

The front page is judged and output because the DC is not equal to 1 so the page displays John Doe

 <  if  condition  = "$DC ==1"               >  <  b  >  Zhang San </ b           >  <  else               />  <  i  >  John Doe </ i         >  </ if  >  

⑤-- <literal> tags are displayed as-is,<if> tags <foreach> labels are not executed in this tag. Judgment and Loop

Four Get form data　　　　

①--by Get_defined_constants (true); method gets the path of the method and returns a two-dimensional associative array

--The path is in ' user ' so Var_dump (Get_defined_constants (true) [' user ']);

--Root path of __root__ TP frame

--The path of __self__ 's own method

--__app__ Entry directory

--__module__ Current module path

--__CONTROLLER__ to the Controller directory

--__action__ to the directory of Operation Methods

②--Front-End CREATE view page sub.html and write to form form, submit address to This page action method directory __action__

<formAction= "__action__"Method= "POST">    <inputtype= "text"name= "UID">    <inputtype= "Password"name= "pwd">    <inputtype= "Submit"value= "Login"></form>

③--some sub methods in the test controller to get the data

     Public functionSub () {if(Empty($_post)){            $this-Show (); //if post is empty, continue to show submission page}Else{            Echo $_post[' UID ']; //If there is a post then operate on it, or output or deposit the database, etc.        }        Var_dump(get_defined_constants(true) [' User ']); }
