Form maxlength

corblimey

I have a form on my page where I've set the maxlength to 20. All well and good, however, the client wants to be able to enter double quotes into that field now and then. If I just allow them to enter "Hello", then when I'm showing that value in the form field later, I'll get
[PHP]<input type="text" value=""Hello"">[/PHP]
which will result in at the very least an empty field. So I have a bit of encoding on the the php backend to handle the double quotes, converting it to ". This worked well until I entered
[PHP]"This is 16 chars"[/PHP]
This converts to
[PHP]"This is 16 chars"[/PHP]
and when written back to the form field becomes
[PHP]"This is 16 cha[/PHP]
because of maxlength limit

So is there something I'm missing when it comes to encoding double quotes for size limited fields?

Are you using PHP?

Then you need to look into stripslashes.

If you use MySQL you're better of looking into mysql-real-escape-string

I normally swap double-quotes with two single quotes to achieve this.

hobbit, I'm using both, but the issue is less to with how the value is saved and more with how to display double quotes in form field. I could use " no issue but the size limitation is cutting it off.

Liam, the two single quotes idea is a good one, although they still take up more room than one double quote, and the client will notice when modifying the field containing ''Hello'' rather than "Hello".
