Php Tinymce编辑器从数据库问题中检索数据[条带化反斜杠]

保存到数据库是好的

var emailReg = /^([\w-\.]+@([\w-]+\.)+[\w-]{2,4})?$/;   

从数据库检索会去掉我的反斜杠

var emailReg = /^([w-.]+@([w-]+.)+[w-]{2,4})?$/;

我正在做一个使用CodeIgniter的项目。 我有一个验证电子邮件地址的表单，如果确定，则保存到DB。 我使用的是Tinymcetextarea编辑器，我将数据保存到这个数据库，我的页面显示ok。 问题是，当我将数据返回到textarea时，由于缺少反斜杠，验证无法工作

var emailReg = /^([w-.]+@([w-]+.)+[w-]{2,4})?$/;

我不确定这是来自CodeIgniter还是Tinymce的问题
