在 Codeigniter 中为卖家创建和添加自定义组

Question

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);
                  }
                 ?>

        }
        if (isset($groups_in)) {
            foreach ($groups_in as $group) {
                $this->db->where('vendor_id', $id);
                $this->db->where('groupid', $group);
                $_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++;
                    }
                }
            }
        }
    } else {

                }
                $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;
}

}

我在输出中得到这个错误：

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

正如我从您在视图中的代码中看到的那样，您已将 foreach($vendor_groups 定义为 $group) 并在声明下拉菜单时 "render_select_with_input_groups('groups_in[]',$groups, ....)" 你已经声明了 $groups 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);
      }
 ?>
