如何在 MySql 中保存 DIV 的内容？
我有连接 index.php 和 mydata_post.php 的脚本，我在其中调用要保存在 MySql 中的数据。
现在的问题是，在 DIV 中显示数据后，我尝试将数据保存到哪里，但 MySql 表中的内容为空。
如果我从 Input 而不是 Div 调用脚本，则该脚本有效。
我要保存的div内容在:
<form name="form1" method="POST" action="mydata_post.php">
<div id="name2" name="name"></div>
<div id="lastname2" name="lastname"></div>
<input type="submit" name="Submit" value="Submit">
</form>
任何人都可以提供帮助，哪里可能是错误的？

最佳答案
您必须使用输入，而不是 div，以便通过表单传递它们的内容。这行不通:
<div id="name2" name="name"></div>
这将:
<input type="text" name="name" value="" />
另外，在 mydata_post.php 中使用它时，您在 HTML 中缺少“电子邮件”输入。所以你必须使用这样的东西:
<form name="form1" method="POST" action="mydata_post.php">
<input type="text" id="name2" name="name" value="" />
<input type="text" id="lastname2" name="lastname" value="" />
<input type="text" id="email2" name="email" value="" />
<input type="submit" name="Submit" value="Submit">
</form>
还记得在使用 mysql_real_escape_string 的 SQL 请求中使用数据之前对数据进行转义.或者切换到 PDO 或 mysqli 并使用准备好的语句。
