Question

嗨，我正在尝试将第一个td值显示为静态，所以我将这些值保留在一个数组中，我尝试增加这些值并尝试显示，但是当我得到它时，如果有在foreach中有一条记录显示一个值，如果我有2条记录，则显示两个值。

但是如果我在foreach中也有值，我想显示所有td值。

这是我的代码：

 <tbody>
                                <?php
                              $arr = array(0=>'On Hold',1=>'Asset Incomplete',2=>'SME Discussion',3=>'a',4=>'b',5=>'c',6=>'d',7=>'e',8=>'f',9=>'g',10=>'h');
                              $i = 0;
                                foreach($getCourse as $report)
                                  $status= $report->status;
                                  {
                                    ?>
                                  <tr>
                                      <td><?php echo $arr[$i]; ?>
                                      <?php $i++;  ?></td>
                                    <td><?php
                                                 if($status==1)
                                                 {
                                                    echo "On Hold";

这是我的控制人：

public function index()
{
        if ($this->session->userdata('is_logged')) {
        $data['getCourse']=$this->Report_model->getTopicReports();
    $this->load->view('template/header');
        $this->load->view('reports/report',$data);
        $this->load->view('template/footer');
}
    else {
        redirect("Login");
    }
}

这是我的模特：

public function getTopicReports()
{
     $this->db->select('count(t.status) as statuscount,t.topicName as topicname,c.coursename,t.status')
     ->from('topics t')
     ->join('course c', 't.courseId = c.id')
     ->where('t.courseid',1)
     ->where('t.status',5);
     $query = $this->db->get();
     return $query->result();
}

最终更新和工作版本

对我来说，这很棘手。原来这是我觉得很尴尬的索引问题。

问题是您的数据不能很好地优化以适应您要执行的任务。遍历表格时，您必须进行奇怪的比较。我能够完成它。

我实际上对看到一种更精致的方法非常感兴趣。但是在此之前，此代码将动态生成一个表，该表与您在问题中发布的示例图片的输出匹配。

我已经用一些示例数据测试了此代码，这些示例数据与您在注释中发布的数组结构相匹配。

代码如下：

//Create an array with your status values.
$rowName = array(

  'On Hold',
  'Asset Incomplete',
  'Yet to Start',
  'SME Discussion',
  'Development',
  'PB Review',
  'PB Fixes',
  'PB2 Review',
  'PB2 Fixes',
  'Alpha Development',
  'Alpha Review',
  'Alpha Fixes',
  'Beta Review',
  'Beta Fixes',
  'Gamma'

);

//Generate a list of class names and get rid of any duplicates.
foreach($getCourse as $report){

  $courseNames[] = $report->coursename;

}

$courseNames = array_unique($courseNames);


//Create the header.
echo
'<table>
  <thead>
    <tr>
      <th>#</th>';

      foreach($courseNames as $course){

        echo '<th>' . $course . '</td>';

      }

    echo
      '<th>Total</th>
    </tr>
  </thead>

<tbody>';

  //Iterate across the array(list) of status values.
  for($i = 0; $i < count($rowName); $i++){

    echo
    '<tr>';

        echo '<td>' . $rowName[$i] . '</td>';

        //Iterate through all combinations of class names and status values.
        for($j = 0; $j < count($courseNames); $j++){

          //Set flags and intial values.
          $found = FALSE;
          $total = 0;
          $value = NULL;

          for($k = 0; $k < count($getCourse); $k++){

            //***Note - The ""$getCourse[$k]->status - 1" is because the status values in your data do not appear
            //to start with an index  of 0.  Had to adjust for that.

            //Sum up all the values for matching status values.
            if(($getCourse[$k]->status - 1) == $i){

              $total += $getCourse[$k]->statuscount;

            }

            //Here we are checking that status row and the status value match and that the class names match.
            //If they do we set some values and generate a table cell value.
            if(($getCourse[$k]->status - 1) == $i && $courseNames[$j] == $getCourse[$k]->coursename){

              //Set flags and values for later.
              $found = TRUE;
              $value = $k;

            }

          }

          //Use flags and values to generate your data onto the table.
          if($found){

            echo '<td>' . $getCourse[$value]->statuscount . '</td>';

          }else{

            echo '<td>' . '0' . '</td>';

          }

        }

        echo '<td>' . $total . '</td>';

   echo
   '</tr>';

  }

echo '</tbody>
</table>';

Answer 2

尝试一下。我将课程状态存储在$used_status中，然后显示未显示在foreach中的剩余状态。

$arr = array ( '1' =>'On Hold', '2' => 'Asset Incomplete', '3' => 'SME Discussion', '4' => 'a', '5' => 'b', '6' => 'c', '7' =>'d', '8' => 'e', '9' => 'f', '10' => 'g', '11' => 'h' );
    $used_status = array();
    foreach($getCourse as $report) { ?>
        <tr>
            <td>
                <?php $course_status = isset($arr[$report->status]) ? $arr[$report->status] : "-";
                echo $course_status;
                $used_status[] = $course_status; ?>
            </td>
            <td>
                <?php echo $report->coursename; ?>
            </td>
            <td>
                <?php echo $report->statuscount; ?>
            </td>
        </tr>
    <?php }
    foreach($arr as $status) {
        if(!in_array($status, $used_status)) { ?>
            <tr>
                <td>
                    <?php echo $status; ?>
                </td>
                <td>
                    <?php echo "-"; ?>
                </td>
                <td>
                    <?php echo "-"; ?>
                </td>
            </tr>
        <?php }
    } ?>
