Question

这已经消耗了我的星期六。请帮忙。

我有一个大表单，我需要更新GoDaddy共享帐户上托管的MySQL数据库表中的记录。在提交表单时，我有18条记录试图更新，但到目前为止，我只有17条记录。当我将其包含在UPDATE语句中时，倒数第二个字段＆＃34; blackTowellCount＆＃34;会导致问题。

如果从SQL语句中排除有问题的字段，则所有18个字段都成功将数据发送到PHP文件，并且SQL语句中列出的17个字段上传就好了。当我包含blackTowellCount字段时，UPDATE停止工作，表单不再将数据发送到PHP表单。 WTF？！

您还会注意到，这里有一个几乎相同的字段，＆＃34; whiteTowellCount＆＃34;更新就好了。

表单的一部分：

<div class="well">
               <div class="row">
                 <div class="col-md-1">
                 </div>
                 <div class="col-md-2"> 
                   <label for="blackTowellCount" class="pull-right">Black Towells</label>
                 </div>
                 <div class="col-md-3">
                      <input type="text" class="form-control" id="blackTowellCount" name="blackTowellCount" placeholder="black towell #"/>
                 </div>
                 <div class="col-md-2">
                         <label for="whiteTowellCount" class="pull-right">White Towells</label>
                 </div>
                 <div class="col-md-3">                
                   <input type="text" class="form-control" id="whiteTowellCount" name="whiteTowellCount" placeholder="white towell #"/>
                 </div>
                 <div class="col-md-1">
                 </div>


               </div>       
             </div>

Answer 1

嗨首先，因为所有人都建议您的代码向SQL injections开放，请改用PDO。第二个php的功能是显示错误，包括它们，如果你不想做的话。

在页面顶部添加这些行

error_reporting(E_ALL);
ini_set('display_errors',1);

你还没有给mysqli_error()个参数

将die(mysqli_error());替换为die(mysqli_error($link));

Answer 2

There was a space in front of "blackTowellCount" in the database. I hate programming.

一个字段保持SQL UPDATE语句不起作用
