【问题描述】：

我是 Codeigniter 的新手，任务是基于 Codeigniter 在 Perfex CRM 中创建和添加自定义组

view.php

 <?php 
                 $selected = array();
                 if(isset($vendor_groups))
                   foreach($vendor_groups as $group)
                      array_push($selected,$group['groupid']);
                   
                 
                 if(is_admin() || get_option('staff_members_create_inline_customer_groups') == '1')
                  echo render_select_with_input_groups('groups_in[]',$groups,array('id','name'),'vendor_groups',$selected,'<a href="#" data-toggle="modal" data-target="#customer_group_modal"><i class="fa fa-plus"></i></a>',array('multiple'=>true,'data-actions-box'=>true),array(),'','',false);
                   else 
                    echo render_select('groups_in[]',$groups,array('id','name'),'vendor_groups',$selected,array('multiple'=>true,'data-actions-box'=>true),array(),'','',false);
                  
                 ?>

                $_exists = $this->db->get(db_prefix().'vendor_groups')->row();
                if (!$_exists) 
                    if (empty($group)) 
                        continue;
                    
                    $this->db->insert(db_prefix().'vendor_groups', [
                        'vendor_id' => $id,
                        'groupid'     => $group,
                    ]);
                    if ($this->db->affected_rows() > 0) 
                        $affectedRows++;

    if ($affectedRows > 0) 
        return true;
    

    return false;

我在输出中收到此错误：

A PHP Error was encountered Severity: Notice

Message: Undefined variable: groups

Filename: groups/profile.php

Line Number: 70

在数据库中，我创建了特殊的表和键，那里一切正常

【问题讨论】：

如何将变量发送到视图？显示控制器的基本部分（顺便说一句，将显示的模型代码也减少到基本部分）

我们需要看看 Filename: groups/profile.php 中第 70 行附近发生了什么。

【参考方案1】：

正如我在视图中的代码中看到的那样，您已经定义了 foreach($vendor_groups as $group) 并且在声明下拉菜单 "render_select_with_input_groups('groups_in[]',$groups,....)" 时，您已经声明了 $组而不是 $group。

代码应该如下所示。

view.php

 <?php 
     $selected = array();
     if(isset($vendor_groups))
       foreach($vendor_groups as $group)
          array_push($selected,$group['groupid']);
       
     
     if(is_admin() || get_option('staff_members_create_inline_customer_groups') == '1')
      echo render_select_with_input_groups('groups_in[]',$group,array('id','name'),'vendor_groups',$selected,'<a href="#" data-toggle="modal" data-target="#customer_group_modal"><i class="fa fa-plus"></i></a>',array('multiple'=>true,'data-actions-box'=>true),array(),'','',false);
       else 
        echo render_select('groups_in[]',$groups,array('id','name'),'vendor_groups',$selected,array('multiple'=>true,'data-actions-box'=>true),array(),'','',false);
      
 ?>
