Using thinkphp automatic completion to implement an infinite class of classification examples _php examples

First, the realization effect

　

Second, the main code

1, template

　2. Controller

Index Module

Add Module

　

3. Model

Third, the Code

So you can reader copy the test.

　1, template

<form action= "__url__/add" method= "POST" >
column <select name= "FID" size=20> <option
"0" > Columns </option>
<volist name= ' list ' id= ' vo ' >
<option value= ' {$vo [' id ']} ' >
{$vo [' Blank ']}{$vo [' name ']}</option>
</volist>
</select><br/>
Add column: <input type = "text" name= ' name '/><br/>
<input type= "Submit" value= "Add"/>
</form>

　　2. Controller

<?php
class Indexaction extends Action
{
/**
+------------------------------------------------ ----------
* Default action
+----------------------------------------------------------/public
function Index () {
$Column =new columnmodel ();
$list = $Column->field ("Id,name,fid,sort,concat (Sort, '-', id) nsort")->order (' nsort asc ')->select ();
foreach ($list as $key => $val) {
$layer =count ('-', $list [$key] [' nsort ']);
$list [$key] [' Blank ']= '];
For ($i =0 $i < $layer; $i + +) {
if ($i = = $layer-1) {
$list [$key] [' Blank '].= '---| ';
} else{
$list [$key] [' Blank '].= '---'
;
}
}} $this->assign (' list ', $list);
$this->display ();
}
Public function Add () {
$Column =new Columnmodel;
$Column->create ();
if ($Column->add ()) {
$this->success (' Add success ');
} else{
$this->error ($Column->geterror ());}} 
? >

　3. Model

<?php
class Columnmodel extends model{
protected $_auto=array (
array (' name ', ' trim ', 0, ' function '),// Filter the blank character
array (' sort ', ' createsort ', 0, ' callback ') that the user accidentally enters
;
*
* Auto-complete sort field
* Query the superior sort based on the FID from the post to determine that this level of sort
*
/protected function Createsort () {
$fid =$ _post[' FID ']? (int) $_post[' FID ']:0;//if the user does not select a parent column, the default parent column ID is 0
if ($fid!= ' 0 ') {
$list = $this->where ("id= $fid")-> Find ();
$data = $list [' sort ']. -'. $fid;
} else{
$data = ' 0 ';
}
return $data;
}

The above is a small set of thinkphp to introduce the automatic completion of the implementation of an unlimited number of classification examples, I hope to help you, if you have any questions please give me a message, small series will promptly reply to everyone. Here also thank you very much for the cloud Habitat Community website support!
