[英]How to change background color of table row if quantity column has numeric value less than 10
[英]How to change background color of table row if quantity column has numeric value less than or equal to 10
我正在實施布料購物網站,在該網站中,管理員將庫存添加到庫存中,並且管理員也可以查看,更新和刪除庫存。 在數據庫中的表中顯示記錄時,我希望客戶購買該行顏色后,具有數量的庫存項目變為10或少於10,因此該行顏色變為紅色,因此應提醒管理員特定的庫存數量少。 這是我的代碼:
<table>
<tr>
<th>Sr.No</th>
<th>Product ID</th>
<th>Brand</th>
<th>Price</th>
<th>Gender</th>
<th>Category</th>
<th>Material</th>
<th>Size</th>
<th>Description</th>
<th>Quantity</th>
<th>Image</th>
</tr>
<?php
$query = "SELECT * FROM add_stock ORDER BY id DESC";
$rs_result = mysqli_query ($query);
while ($result=mysqli_fetch_array($rs_result) )
{
?>
<?php $qty =$result['dress_quantity']; ?>
<tr <?php if($qty<=10){echo 'style="background:red"';} ?> >
<td><?php echo $result['id']; ?></td>
<td><?php echo $result['brand_name'];</td>
<td><?php echo $result['price']; ?></td>
<td><?php echo $result['gender_name']; ?></td>
<td><?php echo $result['category_name']; ?></td>
<td><?php echo $result['material_name']; ?></td>
<td><?php echo $result['size_name']; ?></td>
<td><?php echo $result['dress_description']; ?></td>
<td><?php echo $result['dress_quantity']; ?></td>
<td><a href="javascript:window.open('<?php echo $result['image'] ?>','mypopuptitle', '_parent')" >View Image</a></td>
</tr>
</table>
<?php
}
?>
CSS代碼:
table {
color: #333;
font-family: Helvetica, Arial, sans-serif;
border-collapse:
collapse; border-spacing: 0;
}
td, th {
border: 1px solid; /* No more visible border */
height: 30px;
transition: all 0.3s; /* Simple transition for hover effect */
}
th {
background: #DFDFDF; /* Darken header a bit */
font-weight: bold;
text-align: center;
height: 50px;
}
td {
background: #FAFAFA;
height: 40px;
}
/* Cells in even rows (2,4,6...) are one color */
tr:nth-child(even) td { background: #F1F1F1; }
/* Cells in odd rows (1,3,5...) are another (excludes header cells) */
tr:nth-child(odd) td { background: #FEFEFE; }
在CSS中創建一個類,如.isLess
.isLess { background-color:red;}
然后執行以下操作:
一個三元運算符,回顯該類,如果qty <10,則添加該類,否則不輸出任何內容。
<tr <?php echo ($result['dress_quantity'] < 10 ? "class='isLess'" : ""); ?> >
<td><?php echo $result['id']; ?></td>
<td><?php echo $result['brand_name'];</td>
<td><?php echo $result['price']; ?></td>
<td><?php echo $result['gender_name']; ?></td>
<td><?php echo $result['category_name']; ?></td>
<td><?php echo $result['material_name']; ?></td>
<td><?php echo $result['size_name']; ?></td>
<td><?php echo $result['dress_description']; ?></td>
<td><?php echo $result['dress_quantity']; ?></td>
<td><a href="javascript:window.open('<?php echo $result['image'] ?>','mypopuptitle', '_parent')" >View Image</a></td>
</tr>
或者,您可以執行類似
$class = "";
if($result['dress_quantity'] < 10) { $class='isLess'; }
<tr <?php echo $class; ?> >
