[英]How can I change the background color of div if the condition is met?
Here is the code for notification code: 这是通知代码的代码:
<?php if(isset($notification) && $notification->result() >0 ){?>
<div class="panel-heading pull-right col-md-6"
style="height:140px; margin-top:-140px; background-color:white; overflow-y: scroll;">
<h5><strong>Student with 3 Consecutive Absences</strong></h5>
<table class="table">
<thead>
<th>Course Code-Section</th>
<th>Student Name</th>
<th>View</th>
</thead>
<tbody>
<?php foreach($notification->result() as $notif)
{
if($notif->Total >=3)
{
?>
<tr>
<td><?php echo $notif->Course_Code_Section?</td>
<td><?php echo $notif->Student?></td>
<td>
<form action="<?php echo base_url();?>index.php/attendance/check" method="post" target="_blank">
<input type="hidden" name="CID" value="<?php echo $notif->CID;?>">
<button class="btn btn-xs btn-success"><i class="icon-eye-open"></i> View</button>
<?php echo form_close();?>
</td>
</tr>
</div>
<?php }?>
<?php }?>
</tbody>
</table>
</div>
<?php }?>
Here is the notification view, the default background color is white. 这是通知视图,默认背景颜色为白色。 Therefore, I want it to make the background color red when the condition met.
因此,我希望在满足条件时将背景颜色设为红色。
Try this: 尝试这个:
<?php
$style = '';
if(isset($notification) && $notification->result() > 0 )
{
$style = 'style="color:red"';
// Put your css style property here
}
?>
Html: HTML:
<div <?php echo $style ?>>
</div>
If your condition is true in PHP you can just this line in your tag: 如果您的条件在PHP中为true,则可以在代码中添加以下行:
<tr bgcolor="#FF0000">
I don't know if my html code will appear or not. 我不知道我的HTML代码是否会出现。 Please refer this site:
