我已经为我的网站使用php和mysql创建了一个大小的图表。该表是9列宽，但并非总是使用所有列。
到目前为止，我还没有找到一种方法让它跳过列标题为NA的列。希望有人可以对此有所了解或指出我正确的方向。
以下是代码：
if (!empty($insizes)) {
?>
<div class="ui-widget infoBoxContainer">
<div class="ui-widget-header ui-corner-top infoBoxHeading">
<span><?php $products_name = $product_info['products_name']; echo $products_name; ?> Sizing Chart</span></div>
<table border="0" cellpadding="5" cellspacing="0" id="sizeChart" bgcolor="#ffffff" width="100%">
<tbody width="90%">
<tr>
<td>Size</td>
<?php foreach ($headings as $headingo) { $heading = strtolower(str_replace(" ", "<br>", $headingo)); ?>
<td><?php echo ($product_info["$heading"]); ?></td><?php } ?>
<td>Price</td>
</tr>
<?php
foreach ($insizes as $size)
{
$sizeo = strtolower(str_replace(" ", "", $size));
$sizeo = str_replace("-", "", $sizeo);
?>
<tr>
<td> <?php echo $size; ?></td>
<?php
foreach ($measurements as $measurement) {
$measurementx = $sizeo . '_' . $measurement;
?>
<td><?php echo number_format($product_info["$measurementx"], 0, '.', ''); ?>"<br><span class="sizeChartSm">(<?php echo number_format($product_info["$measurementx"] * 2.54, 1, '.', ''); ?>cm)</span></td>
<?php
}
?>
<td>
<?php
echo $sizeprices["$size"];
?>
</td>
</tr>
<?php
}
?>
</tbody>
</table>
</div>
</p>
<?php
}
非常感谢！ 克里斯

我是否应该能够使用标记（例如NA和0）的if，else语句来存储在数据库中的数据？像这样：
<?php if ($heading != "NA") {?>
<td><?php echo ($product_info["$heading"]); ?></td><?php }} else { ?>
<td>Price</td>
</tr>
<?php } ?>
和
<?php if ($measurement != 0) {?>
<td><?php echo number_format($product_info["$measurementx"], 0, '.', ''); ?>"<br><span class="sizeChartSm">(<?php echo number_format($product_info["$measurementx"] * 2.54, 1, '.', ''); ?>cm)</span></td>
<?php
}} else {
?>
<td>
<?php
echo $sizeprices["$size"];
?>
</td>
</tr>
<?php
}}
?>
但是我似乎无法正确使用语法并继续抛出T_ELSE错误。

跳过列会导致表格绘制错误。
<table>
<tr>
<td>1</td>
<td>2</td>
<td>3</td>
</tr>
<tr>
<td>1</td>
... skipped
<td>3</td>
</tr>
将呈现为
1 2 3
1 3
不
1 2 3
1 3

您应修改$ headings和$ insizes以隐藏某些列或更改脚本的逻辑。但我认为你可以很容易地修改用于生成表的数组。请展示如何构建这两个数组。
答案 2 :(得分：0)
我认为您的错误来自if else语句的括号过多。试试这个：
<?php if ($measurement != 0) {?>
<td><?php echo number_format($product_info["$measurementx"], 0, '.', ''); ?>"<br><span class="sizeChartSm">(<?php echo number_format($product_info["$measurementx"] * 2.54, 1, '.', ''); ?>cm)</span></td>
<?php
} else {
?>
<td>
<?php
echo $sizeprices["$size"];
?>
</td>
</tr>
<?php
}
?>
此外，如果您使用短标记来回显表中的变量，那么您的代码看起来会更清晰：
<?php if ($measurement != 0) {?>
<td>
<?=number_format($product_info["$measurementx"], 0, '.', '')?>
<br>
<span class="sizeChartSm">
(<?=number_format($product_info["$measurementx"] * 2.54, 1, '.', '')?>cm)
</span>
</td>
<?php } else { ?>
<td>
<?=$sizeprices["$size"]?>
</td>
</tr>
<?php } ?>
