Re: addslashes + stripslashes + mysql question

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



You have the string " ' \ "
With addslashes it becomes " '\ \\ "

When you insert it into the database
it goes into a query like this

"update table set field=' '\ \\ ' "

But that inserts into the field only " ' \ ",
in other words the original string. 

It is a normal behaviour and you should 
omit the stripslashes function.

Hope it helps
