Обсуждение: newlines won't display in browser

Hi,

hi, how do you put a newline in a TEXT data type?

when inputting from a form into a textarea box..the return key creates
a newline, which is reflected in psql monitor but not when displaying
the page with php

when I try inputting \n in the browser textarea form, they appear in
the webpage for some reason, in psql monitor, they appear as "\n" but
also make a newline

Do newlines show up in HTML?  No, they don't, you have to use a <br /> tag
for that, which is why PHP provided the nl2br() function.

I'd suggest doing this in your postgresql statement. Makes it easy when
you use views and don't want to use php functions everywhere to do the
task that postgresql can do for you.

Perhaps plphp ? (since you know php)

https://www.commandprompt.com/entry.lxp?lxpe=294

# Here is an example plphp function.

CREATE OR REPLACE FUNCTION line_breaks(text) RETURNS text AS '

   $txt = str_replace("\n","<br>\n",$arg0);

   if ($txt) {

     return $txt;

   }

   else {

     return $arg0;

   }

' LANGUAGE 'plphp';


Then on a select, I'd run

SELECT id, line_breaks(textbox_field) as textbox_field FROM table;

It would then replace all instances of \n with <br>\n.


Cheers,

Robby
