CI Framework Notes 2

1,

<input type="radio" name="type" value="0" <?php echo set_radio(&#39;type&#39;,&#39;0&#39;,TRUE)?> />普通
<input type="radio" name="type" value="0" <?php echo set_radio(&#39;type&#39;,&#39;0&#39;,TRUE)?>/>情感

2,

<select name="cid" id="">
<option value="1" <?php echo set_select(&#39;cid&#39;,&#39;1&#39;,TRUE)?>>情感</option> 注意：TRUE意思是默认选中的；1是值
<option value="0" <?php echo set_select(&#39;cid&#39;,&#39;2&#39;)?>>生活</option>
</select>

3,

<a href=" <?php echo site_url(&#39;admin/admin/index&#39;)?>">

4, Operation database model

//添加动作
public function add(){
$this->load->library("form_validation");
$status = $this->form_validation->run('cate');
if($status){
//操作模型；
$this -> load -> model( "category_model" ); model( "category_model","cate");给模型起个别名
$data = array(
' cname' => $_POST['cname'],
);
$this -> category_model -> add($data); //执行到模型中的添加方法
}else{
$this->load->helper("form");
$this -> load->view(" admin/add_cate.html");
}
／／注意：模型model是建在application/models/的这个目录下面;
<?php
//栏目管理模型 配置数据库是在 application/config/database.php去配置下 此处时model层
class Category_model extends CI_Model {
//添加
public function add ($data){
//使用AR模型
$this -> db -> insert(&#39;category&#39;,$data);
}
}
?>
}
／＊＊
＊ 开启AR模型 一般文章管理系统会使用到AR模型
＊／
$active_record = TRUE; //可以直接在控制器中$this -> db -> insert();

5, When an error occurs, the return method of bool input class is safer to use.

$this -> input -> post("abc"); 以post的方式接收
$this -> input -> get("abc"); 以get的方式接收
¥this -> input -> server("name");

6. The global function is edited and defined in system/core/common.php

7 , Function definition in common.php

／／定义成功的提示函数
function success($url , $msg){
heard('Content-type:text/html;charset=utf-8');
$url = site_url($url);
echo "<script type=&#39;text/javascript&#39;>alert(&#39;$msg&#39;);location.hrerf=&#39;$url&#39;</script>";
die; 
}
function error($msg){
heard(&#39;Content-type:text/html;charset=utf-8&#39;);
echo "<script type=&#39;text/javascript&#39;>window.history.back();</script>";
}

8, Debug mode

$this -> output -> enable_profiler(TRUE);
