Php 编码点火器->；编辑页面

我尝试访问时出现以下错误：

domain.co.nz/admin/editpage/home/

我得到以下错误：

PHP Fatal error:  Call to a member function getCMSPage() on a non-object in controllers/home.php on line 22 

问题是，我无法理解为什么会将其传回主控制器“主”控制器

默认情况下，将加载我的所有模型-

理想情况

我正试图这样做是加载到一个文本区域的内容进行编辑，当提交被点击时，我希望它返回到同一页的消息说，内容更新

管理模板

<li><?php echo anchor('#','Edit Pages');?>
            <?php if(is_array($cms_pages)): ?>
                    <ul>
                        <?php foreach($cms_pages as $page): ?>
                        <li><a >permalink?>"><?=$page->name?></a></li>
                        <?php endforeach; ?>
                    </ul>
                <?php endif; ?>
                </li> 

查看：

<?php
//Setting form attributes
$formpageEdit = array('id' => 'pageEdit', 'name' => 'pageEdit');
$formInputTitle = array('id' => 'title', 'name' => 'title');
$formTextareaContent = array('id' => 'content', 'name' => 'content');
?>

<section id = "validation"><?php echo validation_errors();?></section>

<h4><?= $title ?> </h4>
<?php
echo form_open('admin/editpage/'.$page->permalink, $formpageEdit);
echo form_fieldset();
echo form_label ('Content', 'content');
echo form_textarea("content", $page['content']);
echo form_submit('submit','Submit');
echo form_fieldset_close();
echo form_close();
?> 

function index(){
        if($this->session->userdata('logged_in')){

        }else{
            redirect('admin/home');
        }
       $page = $this->navigation_model->getCMSPage($this->uri->segment(3));
        $data['cms_pages'] = $this->navigation_model->getCMSPages();
        $data['title'] = $page->name;
        $data['content'] = $this->load->view('admin/editpage', array('page' => $page, TRUE));

        $this->load->view('admintemplate', $data);

    }

我还没有真正测试过这个，但它应该给你一个好的开始。您所要求的是快速完全编码的相当多的工作

这是页面模型，本质上是你发布的，只是做了一些小的调整。最好使用id而不是字符串。在将它们传递给数据库之前，您可能还需要执行一些htmlspecialchars或mysql劫持验证

<?php
/**
 * This is the Page_model model, this model handles the retrieval and modification of all pages.
 *
 **/
class Page_model extends CI_Model {
/**
 * the getCMSPage function retrieves the data from the db given the ID that was passed via $id.
 **/
    function getCMSPage($id = NULL) {
        $this->db->where('permalink', $permalink);
        $query = $this->db->get('pages', 1);

        #check to make sure row's were returned, if so continue, otherwise return false.
        if ($query->num_rows() > 0){
            #set the results into an array and return $row, should return $row['content'], and $row['id'];
            #if you were editing more than one page this is where you would use a foreach($query)
            $row = $query->result_array();
            return $row;
        }else{
            return false;
        }// END if ($query->num_rows() > 0)
    }// END function getCMSPage()
}// END Page_model class
?>

需要整个控制器功能请发布导航_模型中的getCMSPage（）方法。Mike，我已经完成了上面所说的，但是每次我访问“permalink”页面时，似乎都认为它是我访问时的主“主控制器”：我得到了对成员函数getCMSPage（）的调用在第22行的/House/application/controllers/home.php中的非对象上
<?php
/**
 * This is the Page_model model, this model handles the retrieval and modification of all pages.
 *
 **/
class Page_model extends CI_Model {
/**
 * the getCMSPage function retrieves the data from the db given the ID that was passed via $id.
 **/
    function getCMSPage($id = NULL) {
        $this->db->where('permalink', $permalink);
        $query = $this->db->get('pages', 1);

        #check to make sure row's were returned, if so continue, otherwise return false.
        if ($query->num_rows() > 0){
            #set the results into an array and return $row, should return $row['content'], and $row['id'];
            #if you were editing more than one page this is where you would use a foreach($query)
            $row = $query->result_array();
            return $row;
        }else{
            return false;
        }// END if ($query->num_rows() > 0)
    }// END function getCMSPage()
}// END Page_model class
?>

<?php
