插入仅存储第一个数字，余数被忽略
我对我的数据库有疑问。我开发了一个系统，当用户插入值时，它会自动计算百分比。我现在的问题是，我的数据库只存储了第一个数字。例如，如果我输入4000，它将只存储4，并且一开始我认为可能有一些事情发生了3个零但不是它，如果我插入3245，它仍然只存储3。
以下是我的数据库;
以及与此数据库相关的代码。
添加记录：
<form action="" method="post">
<div>
<?php if ($id != '') { ?>
<input type="hidden" name="id" value="<?php echo $id; ?>" />

请指出我做错的地方，导致我的数据库只将第一个数字存储到数据库中。

答案 0 :(得分：2)
number_format将逗号放入千位分隔符中。如果数字是＆gt;那么这将会破坏MySQL（或大多数其他数据库）的任何插入。 1,000 - 例如4,000或3,245。人们需要number_format才能轻松阅读信息，而不是数据库。
