How to preserve hyperlink when submitting via php form into MySQL

Question

I've created a form that stores free text fields into a MySQL database.

All works fine and the data is displayed back as intended when viewed. Except for one niggle.

In an attempt to prevent malicious attacks I have used mysql_real_escape_string to remove any unwanted code from the input.

However, I need to be able to preserve hyperlinks and basic html.

For example, I want to store the following:

<p align="left">Please follow this <a href="link.html">link</a></p>

But the link is being stored as \\"link.html\\" as the quotes are being escaped.

How can I preserve this link and other html?

Many thank

TT

Answer 1

This looks like you quote string twice. Did you turn off magic_quotes_gpc in your php.ini?

Answer 2

那不是mysql_real_escape_string（）-我怀疑这实际上是魔术引号

Answer 3

您可以使用PHP函数stripslashes从引号中删除转义的斜杠：

echo stripslashes($textos);

Answer 4

使用PHP5，最好的方法是使用带有PDO扩展名的准备好的语句-这可以为您处理所有事情。
