How to check lines in textarea

MichaelHe

I have a textarea that I need to limit a little.

I get limit it to a number of charecters, but it is important that there are no more than 4 lines before it is inserted in the database.
I have tried asking people who are good at javascript, and it is not very easy to do that way.

So is it possible to check how many lines (breakes) there are in the message with PHP, so I can stop the insert if it has to many..??

It is not a limit I need, but a check, so I can write "too many lines" and people can try again.

Note, lines in <textarea>'s are not really in an HTML standard. Blooberry says this:

wrap=off: default in Netscape.
wrap=soft: default in IE
wrap=hard.
Then wrap=virutal and wrap=physical are discussed in the notes
http://www.blooberry.com/indexdot/html/tagpages/t/textarea.htm)

But IIRC, I had a problem with Opera 7. It ignored "wrap" completely and acted like IE. So the data would be all on one line, with no way to fix it in HTML.

It's unfortuante, but the only way to get line breaks from the user for sure is to use multiple
<input type="text">'s.
But if you're not worried about standards, wrap=off will work for most browsers, AFAIK.
