如何在codeigniter中查看查询结果

如何在codeigniter中查看查询结果,codeigniter,Codeigniter,我使用了两个查询来获得视图的结果。 要获得resultq1的结果,我使用foreach,但如何才能在视图中获得resultq2的结果 对于resultq1的每一行,我在resultq2中得到记录“reccount” Array ( [0] => stdClass Object ( [reccount] => 0 ) [1] => stdClass Object ( [reccount] => 0 ) [2] => stdClass Object ( [reccoun

我使用了两个查询来获得视图的结果。 要获得resultq1的结果,我使用foreach,但如何才能在视图中获得resultq2的结果

对于resultq1的每一行,我在resultq2中得到记录“reccount”

Array ( [0] => stdClass Object ( [reccount] => 0 ) [1] => stdClass Object ( [reccount] => 0 ) [2] => stdClass Object ( [reccount] => 0 ) [3] => stdClass Object ( [reccount] => 2 ) ) 0002
//控制器

     //Query 1
     $q = $this->db->select(array(
                'spf.id as id' ,
                'spf.name',
                "if(u.username != '',u.username,spf.added_by) as added_by ",
                'spf.added_on'
              ))->from('sp_forum spf')->join('sp_users u', 'spf.added_by = u.id', 'left')->where($where)->order_by('spf.id desc')->limit(10, $page * 10)->get();

            $resultq1= $q->result_array();
            $data['resultq1'] = $resultq1;

            $resultq2 = array();
             $i=0;
            foreach($resultq1 as $rec)
             {
                      //query 2
                 $id = $rec['id'];
                 $q1 = $this->db->select("count('id') as reccount ")->from('sp_forum_topic spft')->where('spft.forumid',$id)->get();
                 $resultq2[$i] =  $q1->row_object();
                 $i++; 
               }

$this->load->view('forumview', $data, true);
//查看文件

<table width="100%">
      <tr>
        <td class="th"> Details</td>
        <td width="5%" class="th"> Answer</td>
        <td width="15%" class="th">Started by</td>
        <td  width="15%" class="th">Created on</td>
      </tr>
      <?php foreach($resultq1 as $row):?>
       <tr>
        <td><?php echo $row['name'] ;?></td>

         <td >---- </td> // here i want to use resultq2

         <td><?php echo $row['added_by'] ;?></td>
        <td ><?php echo $row['added_on'];?></td>
      </tr>
      <?php endforeach;?>
    </table>

您还需要将
$resultq2
传递给视图

在控制器中,在调用视图之前

$data['resultq2'] = $resultq2
现在,您可以在视图中使用
$resultq2


PS-SQL查询应该在模型中,而不是在控制器中。

加载视图之前只需写入“$data['resultq2']=$resultq2”

$data['resultq2'] = $resultq2
$this->load->view('forumview', $data, true);
您可以通过$result2变量在视图中检索它

只需执行
var\u转储($result2)
在视图文件中,您将获得$result2 varaible的完整数据


xbonez是对的,一定要在模型中编写DB查询,controller只用于登录,以及在(模型、视图、库、助手等)之间进行协调。

我对第二个查询进行了一些优化,但逻辑基本相同

$q = $this->db->select(array(
    'spf.id as id' ,
    'spf.name',
    "if(u.username != '',u.username,spf.added_by) as added_by ",
    'spf.added_on'
    ))->from('sp_forum spf')->join('sp_users u', 'spf.added_by = u.id', 'left')->where($where)->order_by('spf.id desc')->limit(10, $page * 10)->get();

    $resultq1= $q->result_array();
    $data['resultq1'] = $resultq1;
    $ids = array();
    foreach($resultq1 as $result)
        $ids[] = $result['id'];

     $resultq2 = $this->db->select("count('id') as reccount ")->from('sp_forum_topic spft')->where_in('spft.forumid',$ids)->get();

    foreach( $resultq2->result_array() as $res )
        $newArr[$res['forumid']] = $res;

    $data['resultq2'] = $newArr;
在resultq2被原始id索引之后,resultq1循环中的id很容易使用,以显示正确的数据

<table width="100%">
      <tr>
        <td class="th"> Details</td>
        <td width="5%" class="th"> Answer</td>
        <td width="15%" class="th">Started by</td>
        <td  width="15%" class="th">Created on</td>
      </tr>
      <?php foreach($resultq1 as $row):?>
       <tr>
        <td><?php echo $row['name'] ;?></td>

         <td >
            <?php

                print_r( $resultq2[$row['id']]);

            ?>
        </td> // here i want to use resultq2

         <td><?php echo $row['added_by'] ;?></td>
        <td ><?php echo $row['added_on'];?></td>
      </tr>
      <?php endforeach;?>
    </table>

细节
答复
开始于
创建于
//在这里,我想使用resultq2
这应该可以解决问题。 修改控制器-另请参见注释
Xbonez:我也使用这个,但问题是如何在我的视图中获得它。请查看我的视图。您可以为我做一件事:在运行此命令时给我返回的内容:
$resultq1=$q->result_array();打印($resultq1)
因为我没有数据库,我可以严格测试数组([0]=>Array([id]=>4[name]=>newforum[added\u by]=>16[added\u on]=>2012-08-04 21:55:12)[1]=>Array([id]=>3[name]=>Third forum[added\u by]=>innovation[added\u on]=>2012-08-04 21:55:12][2]=>Array[id]=>2[name]=>secondary forum[added\u]=>robert[added_on]=>2013-02-18 02:44:38][3]=>Array([id]=>1[name]=>First Forum[added_by]=>joyson[added_on]=>2013-02-18 02:44:38))
$resultq1=$q->result_Array();打印($resultq1)
。你给我的是第二个问题。我需要第一个查询。这就是我认为你现在的问题所在抱歉,你能做一个var_导出,这样我就可以使用这些值了。那会让我更快。thanksarray(0=>数组('id'=>'4','name'=>'新论坛','added_by'=>'jack','added_on'=>'2012-08-04 21:55:12',),1=>数组('id'=>'3','name'=>'第三论坛','added_by'=>'创新','added_on'=>'2012-08-04 21:55:12',),2=>数组('id'=>'2','name'=>'Second Forum','added_by'=>'robert','added_on'=>'2013-02-18 02:44:38',3=>数组('id'=>'1','name'=>'First Forum','added_by'=>'joyson','added_on'=>'2013-02-18 02:44:38',),)
