//r /n's and stupid things

saltious

Hi All.

i have html text area that is used to display a field. The user can then edit this field and then save it back to the database.

when saving back i output the text contained within to the user on a page say..... calll update etce etc.

however, if my text has any paragraph spaes in (like the user pressed return while typing in the text area) i get fun /n's and strange /r/ things appearing in the variable which captured the text area.

does anyone know how i might get rid of them?

many thanks for your help.

\r\n are line feed/carriage return characters. to complicate matters each popular OS has a different standard:

win: \r\n
mac: \r
unix: \n

i suggest you strip out all of the \r's using [man]str_replace[/man] and only store the \n's in your database. you can then use [man]nl2br[/man] to output to the browser which will convert them all to <br> tags

many thanks for this, i read up on it and it seems the way to go.

my first problem was that i got the following output for str replace.

Warning: Wrong parameter count for str_replace() - do you know why this may be.

secondly. when i tried the nl2br i got neither an error nor did the effect change. i still go all the /n's and things.

thanks for the reply.

...not without seeing your code but i take the error message at it's word 🙂

Not without seeing what you wrote; but [man]str_replace[/man] expects at least three: what to look for, what to replace it with, and the string you're actually trying to use it on.

And, just to check, but you do mean \n when you say /n, right?

hi guys, many thanks for your replies.

i think im stupid.....

ive read up on this function now but still dont quite get it.

im not sure how i use str_replace() to take out the \r and \n's (yea it was that kind of slash weedpacket).

basically its the thing i replace it with. how do i generate that without these funny slashes in?

cheers!!

to strip out all \r's

$text = str_replace("\r", '', $text);
