Probably. But, I now picture a long post having the words LONG POST at the bottom of the post and wonder what the purpose of that is except that it makes the post even longer.
Any idea as to how I could do it? I just said 'LONG POST', it would be something else but I don't think it's appropriate for these forums <_<. Would be "disregard that ...." and if you know it you'll fill in the blank.
Well, you'll have to create a plugin which checks the length of the $post[message] and then if it's longer than xx, you would append "LONG POST" (keeping with the example) to the end.
PHP Code:
if (strlen($post[message]) > '200') $post[message] = $post[message] . "LONG POST";
I'm not sure of the plugin location or variable names (you can look them up in newpost.php file).
But then you are counting on line breaks inserted by the user, no? So they can write a huge paragraph and it would just be considered one line? I guess the OP can try the code and see how it works.
