UPDATE正在更新某些字段，但不更新其他字段

好吧，出于某种原因，这是一个奇怪的。 UPDATE正在更新字段，但它完全绕过这一个字段，我似乎无法找到原因。

该字段为 partdesc

以下是整个代码：

<?php
require_once('connectvars.php');
echo '<div id="postwrap">'

据我所知，这些部分正在处理有问题的代码。

清理剧本的部分：

   $partdesc = cleanPostVar($dbc,'partdesc');

更新脚本的部分。

$query = "UPDATE ncmr SET ab = '$ab', date = '$date', part = '$part', rev = '$rev' , partdesc = '$partdesc' , ncmrqty = '$ncmrqty' , comp = '$comp' , ncmrid = '$ncmrid' , rma = '$rma' , jno = '$jno' , fdt = '$fdt' , cof = '$cof' , fab1 = '$fab1' , fab2 = '$fab2' , fab3 = '$fab3' , non = '$non' , dis = '$dis' , comm = '$comm' , caad = '$caad' , po = '$po' , pod = '$pod' , dri = '$dri'  WHERE id = '$id'";

显示所述字段描述的部分，如果没有，则在字段中输入Empty，直到由其他人输入。

if (empty($row['partdesc'])) $row['partdesc'] = "Empty";

            echo '<div id="partdesc"><span class="b">Part Description:&nbsp;&nbsp;</span><textarea rows="4" cols="22">' . $row['partdesc'] . '</textarea></div>';

就是这样。每个人都有一种形式或另一种形式正确地认为你是 partdesc 。现在还要记住，这也是在Notepad ++中编辑的，并且在没有BOM的情况下以UTF +8进行编码，因此就我所知的代码而言，没有任何不确定性。

是否有我遗漏的东西，或者这只是因为所有其他代码都在发布，而且它看起来完全相同。

答案 0 :(得分：3)

您的textarea没有name属性。由于$_POST中的密钥基于名称，这意味着文本不会存储在您认为的位置。

调试这样的问题的好方法是在php文件的开头打印出$_POST的值，以便确保它实际包含您期望的数据。如果您认为特定的SQL查询失败，那么一个好的调试策略是打印出查询，以便您可以手动尝试并查看SQL对象。
