我有一个代码点火器的现有项目，并希望开始使用杂货crud . 我在最近安装的wamp，php 5.4，apache 2.4.4上运行它 .
我按照基本设置，将文件复制并粘贴到我的代码igniter目录，然后设置一个控制器来显示一个带有crud功能的表，如教程中所示，但是在查看时出现以下错误：
致命错误：未捕获的异常'异常'，消息'在状态'更新“你必须有帖子数据”在第3185行的C：\ wamp \ www ... \ application \ libraries \ Grocery_CRUD.php
控制器：
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class Previousqualification extends CI_Controller {
function __construct(){
parent::__construct();
/* Standard Libraries of codeigniter are required */
$this->load->database();
$this->load->helper('url');
/* ------------------ */
$this->load->library('grocery_CRUD');
}
public function test(){
$this->grocery_crud->set_table('previousqualification');
$output = $this->grocery_crud->render();
$this->_crud($output);
}
function _crud($output = null){
$this->load->view('view_previousqualification.php',$output);
}
}
在控制器中引用的视图：
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8" />
<?php
foreach($css_files as $file): ?>
<link type="text/css" rel="stylesheet" href="<?php echo $file; ?>" />
<?php endforeach; ?>
<?php foreach($js_files as $file): ?>
<script src="<?php echo $file; ?>"></script>
<?php endforeach; ?>
<style type='text/css'>
body
{
font-family: Arial;
font-size: 14px;
}
a {
color: blue;
text-decoration: none;
font-size: 14px;
}
a:hover
{
text-decoration: underline;
}
</style>
</head>
<body>
<!-- End of header-->
<div style='height:20px;'></div>
<div>
<?php echo $output; ?>
</div>
<!-- Beginning footer -->
<div>Footer</div>
<!-- End of Footer -->
</body>
</html>
我已经改变了我的基本网址，因为我看到这可能是有些类似错误的问题 . 这没有效果 . 我确实在apache和.htaccess中启用了mod_rewrite来摆脱url中的index.php - 这可能是个问题吗？
我一直在查看导致错误的文件（Grocery_CRUD.php），当我调用 render() 方法时会发生这种情况，该方法调用方法 getStateInfo() 调用另一种方法将状态设置为6或'update'，然后检查是否 $_POST 变量在 getStateInfo() 中是空的，我不确定，但到目前为止我只是试图了解究竟发生了什么 . 如果您需要任何信息，请询问 .
.htaccess文件：
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /codeIgniter
#Removes access to the system folder by users.
#Additionally this will allow you to create a System.php controller,
#previously this would not have been possible.
#'system' can be replaced if you have renamed your system folder.
RewriteCond %{REQUEST_URI} ^system.*
RewriteRule ^(.*)$ /index.php?/$1 [L]
#When your application folder isn't in the system folder
#This snippet prevents user access to the application folder
#Submitted by: Fabdrol
#Rename 'application' to your applications folder name.
RewriteCond %{REQUEST_URI} ^application.*
RewriteRule ^(.*)$ /index.php?/$1 [L]
#Checks to see if the user is attempting to acces a valid file,
#such as an image or css document, if this isn't true it sends the
#request to index.php
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php?/$1 [L]
</IfModule>
<IfModule !mod_rewrite.c>
# If we don't have mod_rewrite installed, all 404's
# can be sent to index.php, and everything works as normal.

我有同样的问题 . 这就是我解决它的方法：我删除了与杂货crud库交互的select boostrap库（js文件）......
