这是我的 php 中的产品列表文件，我尝试在 https://stackoverflow.com/a/48837052/12033292 的帮助下显示所有产品的列表。 。 我的类别表名称是category，产品表名称是products。 我从另一个页面获取类别名称并显示此页面中的所有产品
Product list
I want to show all products but in output i see only one product in screen.

这是我的输出，但我想展示我的所有产品
最佳答案
如果您想查看所有产品，您需要循环遍历从查询中获得的所有结果并回显您需要的每个键。
我没有测试这段代码，但这里有一个它应该如何工作的示例:
<table class="product-details">
<tr>
<td class="label">Name</td>
<td class="label">Quantity</td>
<td class="label">Description</td>
<td class="label">Images</td>
</tr>
<?php foreach($products as $product) { ?>
<tr>
<td><?php echo $product['title']; ?></td>
<td><?php echo $product['price']; ?></td>
<td><?php echo $product['description']; ?></td>
<?php foreach ($images as $image) {
$imageId = $image['id'];
$imageFilename = $image['filename']; ?>
<td><img src="admin_4/<?php echo $imageFilename; ?>" alt="" /></td>
<?php } ?>
</tr>
<?php } ?>
</table>
