实例操作文章与栏目相关表单验证：
表单验证操作：application/controllers/admin/article.php
<?php /** * Created by PhpStorm. * User: Administrator * Date: 2017/10/7 * Time: 9:08 */ if ( ! defined('BASEPATH')) exit('No direct script access allowed'); class Article extends CI_Controller{ //发表模板显示 public function send_article(){ //加载表单验证辅助函数 $this ->load ->helper('form'); $this ->load ->view('admin/article.html'); } //发表文章动作 public function send(){ //载入表单类 $this ->load ->library('form_validation'); //配置规则 $this ->form_validation ->set_rules('title','文章标题','required|min_length[5]');//标题不能为空,至少为5个 $this ->form_validation ->set_rules('type','类型','required|integer');//类型不能为空，保存在数据库里为整数； $this ->form_validation ->set_rules('cid','栏目','integer');//保存在数据库里为整数； $this ->form_validation ->set_rules('info','摘要','required|max_length[155]'); $this ->form_validation ->set_rules('content','内容','reguired|max_length[2000]'); //验证规则 $status = $this ->form_validation ->run(); if($status){ echo '数据库操作'; }else{ $this ->load ->helper('form'); $this ->load ->view('admin/article.html'); } } }

<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<link rel="stylesheet" href="<?php echo base_url().'style/admin/css/public.css'?>">
<title>Title</title>
</head>
<body>
<form action="<?php echo site_url('/admin/article/send')?>" method="post" enctype="multipart/form-data">
<table class = "table">
<tr>
<td colspan="10" class="th">发表文章</td>
</tr>
<tr>
<td>标题</td>
<td><input type="text" name="title" value="<?php echo set_value('title') ?>">
<?php echo form_error('title','<span>','</td>') ?>
</td>
</tr>
<tr>
<td>类型</td>
<td>
<input type="radio" name="type" value="0" <?php echo set_radio('type','0','TRUE') ?> > 普通
<input type="radio" name="type" value="1" <?php echo set_radio('type','1') ?>> 热门
</td>
</tr>
<tr>
<td>栏目</td>
<td>
<select name="cid" id="">
<option value="1" <?php echo set_select('cid','1','TRUE') ?>>情感</option>
<option value="2" <?php echo set_select('cid','2') ?>>生活</option>
</select>
</td>
</tr>
<tr>
<td>缩略图</td>
<td>
<input type="file">
</td>
</tr>
<tr>
<td>摘要</td>
<td>
<textarea name="info" id="" style="width: 550px;height: 160px;"><?php echo set_value('info') ?></textarea>
<?php echo form_error('info','<span>','</span>')?>
</td>
</tr>
<tr>
<td>内容</td>
<td>
<textarea name="content" id="" style="width: 550px;height: 160px;"><?php echo set_value('content')?></textarea>
<?php echo form_error('content','<span>','</span>')?>
</td>
</tr>
<tr>
<td colspan="10"><input type="submit" class="input_button" value="发布"></td>
</tr>
</table>
</form>
</body>
</html>
==========================
如何设置编辑和发表共用这一套规则：
1、在application/config/下新建文件名为：form_validation.php（必须是这个名字）
2、写入：
<?php /** * Created by PhpStorm. * User: Administrator * Date: 2017/10/8 * Time: 8:11 */ $config = array( 'article' => array( array( 'field' => 'title', 'label' => '标题', 'rules' => 'required|min_length[5]' ), array( 'field' => 'type', 'label' => '类型', 'rules' => 'required|integer' ), array( 'field' => 'cid', 'label' => '栏目', 'rules' => 'integer' ), array( 'field' => 'info', 'label' => '摘要', 'rules' => 'required|max_length[155]' ), array( 'field' => 'content', 'label' => '内容', 'rules' => 'required|max_length[2000]' ) ), );
3、在application/controllers/admin/article.php 中修改代码，把表单验证规则设置为公共规则：
<?php /** * Created by PhpStorm. * User: Administrator * Date: 2017/10/7 * Time: 9:08 */ if ( ! defined('BASEPATH')) exit('No direct script access allowed'); class Article extends CI_Controller{ //发表模板显示 public function send_article(){ //加载表单验证辅助函数 $this ->load ->helper('form'); $this ->load ->view('admin/article.html'); } //发表文章动作 public function send(){ //载入表单类 $this ->load ->library('form_validation'); // //配置规则 // $this ->form_validation ->set_rules('title','文章标题','required|min_length[5]');//标题不能为空,至少为5个 // $this ->form_validation ->set_rules('type','类型','required|integer');//类型不能为空，保存在数据库里为整数； // $this ->form_validation ->set_rules('cid','栏目','integer');//保存在数据库里为整数； // $this ->form_validation ->set_rules('info','摘要','required|max_length[155]'); // $this ->form_validation ->set_rules('content','内容','reguired|max_length[2000]'); //验证规则 $status = $this ->form_validation ->run('article'); if($status){ echo '数据库操作'; }else{ $this ->load ->helper('form'); $this ->load ->view('admin/article.html'); } } }
====================================================================================
在application/controllers/admin/article.php控制器中添加：编辑文章方法、编辑动作方法
<?php /** * Created by PhpStorm. * User: Administrator * Date: 2017/10/7 * Time: 9:08 */ if ( ! defined('BASEPATH')) exit('No direct script access allowed'); class Article extends CI_Controller{ //发表模板显示 public function send_article(){ //加载表单验证辅助函数 $this ->load ->helper('form'); $this ->load ->view('admin/article.html'); } //发表文章动作 public function send(){ //载入表单类 $this ->load ->library('form_validation'); // //配置规则 // $this ->form_validation ->set_rules('title','文章标题','required|min_length[5]');//标题不能为空,至少为5个 // $this ->form_validation ->set_rules('type','类型','required|integer');//类型不能为空，保存在数据库里为整数； // $this ->form_validation ->set_rules('cid','栏目','integer');//保存在数据库里为整数； // $this ->form_validation ->set_rules('info','摘要','required|max_length[155]'); // $this ->form_validation ->set_rules('content','内容','reguired|max_length[2000]'); //验证规则 $status = $this ->form_validation ->run('article'); if($status){ echo '数据库操作'; }else{ $this ->load ->helper('form'); $this ->load ->view('admin/article.html'); } } //编辑文章 public function editor_article(){ $this ->load ->helper('form'); $this ->load ->view('admin/editor_article.html'); } //编辑动作 public function editor(){ $this ->load ->library('form_validation'); $status = $this ->form_validation ->run('article'); if($status){ echo '数据库操作'; }else{ $this ->load ->helper('form'); $this ->load ->view('admin/editor_article.html'); } } }
相对应的html页面：在application/views/admin下新建editor_article.html，代码如下：
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<link rel="stylesheet" href="<?php echo base_url().'style/admin/css/public.css'?>">
<title>Title</title>
</head>
<body>
<form action="<?php echo site_url('/admin/article/editor')?>" method="post" enctype="multipart/form-data">
<table class = "table">
<tr>
<td colspan="10" class="th">编辑文章</td>
</tr>
<tr>
<td>标题</td>
<td><input type="text" name="title" value="<?php echo set_value('title') ?>">
<?php echo form_error('title','<span>','</td>') ?>
</td>
</tr>
<tr>
<td>类型</td>
<td>
<input type="radio" name="type" value="0" <?php echo set_radio('type','0','TRUE') ?> > 普通
<input type="radio" name="type" value="1" <?php echo set_radio('type','1') ?>> 热门
</td>
</tr>
<tr>
<td>栏目</td>
<td>
<select name="cid" id="">
<option value="1" <?php echo set_select('cid','1','TRUE') ?>>情感</option>
<option value="2" <?php echo set_select('cid','2') ?>>生活</option>
</select>
</td>
</tr>
<tr>
<td>缩略图</td>
<td>
<input type="file">
</td>
</tr>
<tr>
<td>摘要</td>
<td>
<textarea name="info" id="" style="width: 550px;height: 160px;"><?php echo set_value('info') ?></textarea>
<?php echo form_error('info','<span>','</span>')?>
</td>
</tr>
<tr>
<td>内容</td>
<td>
<textarea name="content" id="" style="width: 550px;height: 160px;"><?php echo set_value('content')?></textarea>
<?php echo form_error('content','<span>','</span>')?>
</td>
</tr>
<tr>
<td colspan="10"><input type="submit" class="input_button" value="发布"></td>
</tr>
</table>
</form>
</body>
</html>
===================================================================================
1、在application/controllers/admin下新建栏目管理控制器category.php：
在application/views/admin下新建html页面add_cate.html：
需在后台首页中引入新建模板add_cate.html;<?php echo site_url('admin/category/add_cate')?>
将验证写入到application/config/form_validation.php里面；
编辑栏目：在application/views/admin下新建html页面editor_cate.html
在category.php控制器中写入编辑栏目方法：
附代码：application/controllers/admin/category.php栏目控制器：
<?php /** * Created by PhpStorm. * User: Administrator * Date: 2017/10/8 * Time: 12:03 */ if ( ! defined('BASEPATH')) exit('No direct script access allowed'); class Category extends CI_Controller{ //添加栏目 public function add_cate(){ $this ->load ->helper('form'); $this ->load ->view('admin/add_cate.html'); } // 添加动作 public function add(){ //载入表单验证类库 $this ->load ->library('form_validation'); $status = $this ->form_validation ->run('cate'); if($status){ echo '数据库操作'; }else{ $this ->load ->helper('form'); $this ->load ->view('admin/add_cate.html'); } } //编辑栏目 public function editor_cate(){ $this ->load ->helper('form'); $this ->load ->view('/admin/editor_cate.html'); } //编辑栏目动作 public function editor(){ //载入表单验证类库 $this ->load ->library('form_validation'); $status = $this ->form_validation ->run('cate'); if($status){ echo '数据库操作'; }else{ $this ->load ->helper('form'); $this ->load ->view('admin/editor_cate.html'); } } }
附code：application/views/admin/add_cate.html:
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <link rel="stylesheet" href="<?php echo base_url('style/admin/css/public.css')?>"> <title>Title</title> </head> <body> <form action="<?php echo site_url('/admin/category/add')?>" method="post"> <table class="table"> <tr> <td class="th" colspan="10">添加栏目</td> </tr> <tr> <td>栏目名称</td> <td><input type="text" name="cname" value="<?php echo set_value('cname')?>"> <?php echo form_error('cname','<span>','</span>')?></td> </tr> <tr> <td colspan="10"><input type="submit" value="添加" class="input_button"></td> </tr> </table> </form> </body> </html>
附code：application/views/admin/editor_cate.html:
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <link rel="stylesheet" href="<?php echo base_url('style/admin/css/public.css')?>"> <title>Title</title> </head> <body> <form action="<?php echo site_url('/admin/category/editor')?>" method="post"> <table class="table"> <tr> <td class="th" colspan="10">编辑栏目</td> </tr> <tr> <td>栏目名称</td> <td><input type="text" name="cname" value="<?php echo set_value('cname')?>"> <?php echo form_error('cname','<span>','</span>')?></td> </tr> <tr> <td colspan="10"><input type="submit" value="添加" class="input_button"></td> </tr> </table> </form> </body> </html>
附code：application/config/form_validation.php:公共表单验证规则：
<?php /** * Created by PhpStorm. * User: Administrator * Date: 2017/10/8 * Time: 8:11 */ $config = array( 'article' => array( array( 'field' => 'title', 'label' => '标题', 'rules' => 'required|min_length[5]' ), array( 'field' => 'type', 'label' => '类型', 'rules' => 'required|integer' ), array( 'field' => 'cid', 'label' => '栏目', 'rules' => 'integer' ), array( 'field' => 'info', 'label' => '摘要', 'rules' => 'required|max_length[155]' ), array( 'field' => 'content', 'label' => '内容', 'rules' => 'required|max_length[2000]' ) ), 'cate' => array( array( 'field' => 'cname', 'label' => '栏目名称', 'rules' => 'required|max_length[20]' ), ), );
