How to escape slashes in TEXT boxes?

[AthlonInside]

Assume that I want a TextBox with data

I'm "Superman"

How do I escape the double slashes so the intermediate slashes are not treated as closing slash?

<input type=text value="I'm "Superman"">

Using &quot; doesn't help because I am passing them to MySQL.

It looks as if you are calling this character (') a slash. That is an apostrophe.

If you want to escape the character (') use quotes (") around the string or put a back slant (\) in front of the apostrophe like this (\').

So, to recap:

<input type=text value="I'm \"Superman\""> ...will do it

Now, say that you wanted this text in the box:

A slash looks like this: "\"

How would one go about doing that? :)

<input type=text value="A slash looks like this: \"\\\"">

A slash looks like this: "\"

Uhmm, isn't that a backslash?

[AthlonInside]

Ok, I get the idea.

Sorry, it is definitely not slash, what in my mind is actually 'quote' - single quote and double quote.

/ is a slash
\ is also a slash but back slash.

But as long as we understand each other, do words really matter? :)

I agree. I was just define terms so that I would be sure I was answering the question you asked. :)

What about this

<a href="somefile.php?data=""">

" inside HREF, how to escape?

[tombola]

In that case, you must use an urlencoded string (hexadecimal value of the ASCII character):
Here are a few examples:

space (ASCII = 32) = %20
! (ASCII = 33) = %21
" (ASCII = 34) = %22
# (ASCII = 35) = %23
$ (ASCII = 36) = %24
% (ASCII = 37) = %25
& (ASCII = 38) = %26
' (ASCII = 39) = %27
( (ASCII = 40) = %28
) (ASCII = 41) = %29

So, <a href="somefile.php?data="""> must be written as: <a href="somefile.php?data=%22%22">
