问题描述
<?PHP
$pros_array_id= array_column($_SESSION['cart'],'paint_id');
$productee = $productn->getData('paint');
foreach($productee as $pro):
if($pro['paint_id'] == $pros_array_id):
?>
<table>
<tr>
<td class="imgTag">
<a href="#"><img class="img-fluid" src="<?PHP echo $pro['paint_image'] ?? 1; ?>" ></a>
</td>
</tr>
</table>
<?PHP
endif;
endforeach;
?>
Am trying to display session cart items and its not showing anything. When I print_r($productee) and print_r($pros_array_id) after the foreach statement both display the accurate data,yet nothing displat in the <tr> tag.
是显示结果 当我像这样内爆 $pros_array_id 时 "$imp = implode(" ",$pros_array_id);"并将变量放在 if 语句中,如果会话中只有一种产品,它可以正常工作,但是当我在会话中添加多个产品时,不再显示任何内容。 请问有人可以指点我应该怎么做吗? 谢谢
解决方法
试试这个:
<table>
<?php
$pros_array_id = array_column($_SESSION['cart'],'paint_id');
$productee = $productn->getData('paint');
foreach($productee as $pro) {
//Also see and try to disable this check to see if it works then!
if($pro['paint_id'] == $pros_array_id) { ?>
<tr>
<td class="imgTag">
<a href="#"><img class="img-fluid" src="<?php echo $pro['paint_image'] ?? 1; ?>"></a>
</td>
</tr>
<?php
}
}
?>
</table>
在调试此类代码时始终确保消除任何可能导致错误的检查,因此也尝试禁用“if 子句”,以查看它是否显示某些内容。
