tr bgcolor dependant on row value

本文关键字：依赖于 bgcolor Tr | 更新日期: 2023-09-27

我是php的新手，我有一个表，显示来自我们的支持门户的案例。案例被设置为"高、中或低"的优先级，我希望每行的bgcolor根据该案例的优先级显示不同的颜色。例如:High = Red, Low = White, Medium = Yellow.

下面是我的代码。我该如何实施呢?任何建议将非常感激!

<?php
              $priority = $val['priority'];
                  switch($priority)
                  {
                      case P3:
                       $prior_value = "Low";
                        break;
                      case P2:
                       $prior_value = "Medium";
                        break;
                      case P1:
                       $prior_value = "High";
                  }
?>
 <tr  height="30px">
    <Td class="gridcontentredmid" style="width:65px;"><a href="showcase.php?case_id=<?=$val['id']?>">
      <?=$val['case_number']?>
      </a></Td>
    <Td class="gridcontentmid" style="width:270px; text-align:left;">&nbsp;
      <?=$val['name']?></Td>
    <Td class="gridcontentmid" style="width:85px;" ><?=$val['status']?></Td>
    <Td class="gridcontentmid"><?=$name?></Td>
    <Td class="gridcontentmid" style="width:65px;"><?=$prior_value?></Td>
    <Td class="gridcontentmidd" style="border-right:#000 1px solid"><?=$date_create?></Td>
  </tr>

这里有一个快速的方法:

              $priority = $val['priority'];
                  switch($priority)
                  {
                      case P3:
                       $prior_value = "Low";
                        break;
                      case P2:
                       $prior_value = "Medium";
                        break;
                      case P1:
                       $prior_value = "High";
                  }
                  $colors = array("High" => "red", "Medium" => "yellow", "Low" => "white");
                  $color = $colors[$prior_value];

 <tr style="background-color: <?php echo $color; ?>" height="30px">
    <Td class="gridcontentredmid" style="width:65px;"><a href="showcase.php?case_id=<?=$val['id']?>">
      <?=$val['case_number']?>
      </a></Td>
    <Td class="gridcontentmid" style="width:270px; text-align:left;">&nbsp;
      <?=$val['name']?></Td>
    <Td class="gridcontentmid" style="width:85px;" ><?=$val['status']?></Td>
    <Td class="gridcontentmid"><?=$name?></Td>
    <Td class="gridcontentmid" style="width:65px;"><?=$prior_value?></Td>
    <Td class="gridcontentmidd" style="border-right:#000 1px solid"><?=$date_create?></Td>
  </tr>

但是一个更好的方法是使用CSS:

.priorityHigh {
    background-color: red;
}
.priorityMedium {
    background-color: yellow;
}
.priorityLow {
    background-color: white;
}

和

              $priority = $val['priority'];
                  switch($priority)
                  {
                      case P3:
                       $prior_value = "Low";
                        break;
                      case P2:
                       $prior_value = "Medium";
                        break;
                      case P1:
                       $prior_value = "High";
                  }

 <tr class="priority<?php echo $prior_value; ?>" height="30px">
    <Td class="gridcontentredmid" style="width:65px;"><a href="showcase.php?case_id=<?=$val['id']?>">
      <?=$val['case_number']?>
      </a></Td>
    <Td class="gridcontentmid" style="width:270px; text-align:left;">&nbsp;
      <?=$val['name']?></Td>
    <Td class="gridcontentmid" style="width:85px;" ><?=$val['status']?></Td>
    <Td class="gridcontentmid"><?=$name?></Td>
    <Td class="gridcontentmid" style="width:65px;"><?=$prior_value?></Td>
    <Td class="gridcontentmidd" style="border-right:#000 1px solid"><?=$date_create?></Td>
  </tr>

只需在switch中添加一个$color -变量，然后可以将其插入TR, class或style属性中。

switch($priority)
{
    case P3:
        $prior_value = "Low";
        $bgColor = '#fff';
        break;
    case P2:
        $prior_value = "Medium";
        $bgColor = '#ff0';
        break;
    case P1:
        $prior_value = "High";
        $bgColor = '#f00';
}

…

<tr style="background-color: <?php echo $bgColor; ?>;">
