What terms did you try when SEARCHING for a solution: spaces, multiple spaces, line breaks...

Hi! I have 2 questions, (maybe they are the same):

Q1:
I would like to know if there is a way to avoid a user entering multiple empty lines. In other words: if a user enters something like this:

test

test

I would like to change it into this (turn n empty lines (spaces) into just one):

test

test

Q2:
Another problem is the following: If a user enters a lot of empty lines between words (see example here: http://gabsal.100webspace.net/testingbook/ ) Then a strange < br> tag appears and the end of the comments became bold (in the example I ONLY entered the word "test" at the first line and again the word "test" at the last line). Can that be avoided?

Thanks for your help.

[Maybe a way to avoid these problems would be to set a maximum number of characters that a user can enter in the text field, then that would refrain the user from doing this stupid input. If that is so, do you know how that can be accomplished?]

(Sorry if my questions look too naive; I am a php newbee and my mother tongue is not english!)

So you finally were able to login to the forum

Try opening gbook.php in a plain text editor (Notepad) and change lines 620 to 623 from

Code: Select all

$comments = str_replace("\r\n","<br>",$comments);
$comments = str_replace("\n","<br>",$comments);
$comments = str_replace("\r","<br>",$comments);
$comments = wordwrap($comments,$settings['max_word'],' ',1);

to this:

Code: Select all

$comments = wordwrap($comments,$settings['max_word'],' ',1);
$comments = preg_replace('/(\n|\r)+/','<br>',$comments);

Haven't really tested it so please come back and say if it worked or not.

I think I'll include this in the next version by default.

Thank you again!
