Bbcode function issue

[pandailo]

Hi all,

 

Actually i manage to create bbcode function but there is a problem especially with user accidentally mistype the bbcode

For example, if user type the bbcode like this test, it will give an parse error. How do i solve the issue

 

Here is my bbcode function

 

function getbbcode($text, $ses="", $filtered)

{

  $text = htmlspecialchars($text);

  $text=preg_replace("/\[b\](.*?)\[\/b\]/i","<b>\\1</b>", $text);

  $text=preg_replace("/\[b\](.*?)\[\/u\]/i","<b>\\1</b>", $text);

  $text=preg_replace("/\[i\](.*?)\[\/i\]/i","<i>\\1</i>", $text);

  $text=preg_replace("/\[u\](.*?)\[\/u\]/i","<u>\\1</u>", $text);

  $text=preg_replace("/\[u\](.*?)\[\/b\]/i","<u>\\1</u>", $text);

  $text=preg_replace("/\[big\](.*?)\[\/big\]/i","<big>\\1</big>", $text);

  $text=preg_replace("/\[small\](.*?)\[\/small\]/i","<small>\\1</small>", $text);

  return $text;

}

 

I tried belows way to solve the issue:

$text=preg_replace("/\[b\][u\](.*?)\[\/b\][\/u\]/i","<b>\\1</b>", $text);

$text=preg_replace("/\[b\][u\](.*?)\[\/b\]\[\/u\]/i","<b>\\1</b>", $text);

$text=preg_replace("/\[b\]/\[u\](.*?)\[\/b\]\[\/u\]/i","<b>\\1</b>", $text);

 

but none is working. Anybody can solve the issue?

For BBCode, try this instead, it's what I use

 

$Find = array
(
'/\[b\]/is',
'/\[\/b\]/is',
'/\[i\]/is',
'/\[\/i\]/is'
'/\[u\]/is',
'/\[\/u\]/is',
'/\[big\]/is',
'/\[\/big\]/is',
'/\[small\]/is',
'/\[\/small\]/is'
);

$Replace = array
(
'<b>',
'</b>',
'<i>',
'</i>',
'<u>',
'</u>',
'<big>',
'</big>',
'<small>',
'</small>'
);

$Text = preg_replace($Search, $Replace, $Text);

 

Your problem was it replaced [xx]aa[/xx] with <xx>aa</xx>. You didn't say what to do if the [/xx] wasn't matched with anything. My code tells it to replace, no matter what

[pandailo]

sorry i have to make you clear on this. Actually the actual problem is like below

 

when user type [xx][yy]testing[/xx][/yy]  <-- this is mistype by user and give me parse error. So i do i solve that kind of issue?

[Garethp]

Use my code, again, it will work

[pandailo]

your function is working but the result is empty message(no single word appear in message)..and still not solve..any way to improve it?

im using this one

$txt = str_replace("[b]", "<b>", $txt);
$txt = str_replace("[/b]", "</b>", $txt);
$txt = str_replace("[i]", "<i>", $txt);
$txt = str_replace("[/i]", "</i>", $txt);
$txt = str_replace("[u]", "<u>", $txt);
$txt = str_replace("[/u]", "</u>", $txt);
$txt = str_replace("[quote]", "<div id=quote><b>QUOTE:</b>", $txt);
$txt = str_replace("[/quote]", "</div>", $txt);
$txt = preg_replace("#\[color=(.+?)\](.+?)\[/color\]#is","<font color=\"\\1\">\\2</font>",$txt);

[Garethp]

Nah, I wrote up what you need, here it is

 

<?php

function BBCode($Text)
{
$Find = array
	(
	'/\[b\]/is',
	'/\[\/b\]/is',
	'/\[i\]/is',
	'/\[\/i\]/is',
	'/\[u\]/is',
	'/\[\/u\]/is',
	'/\[big\]/is',
	'/\[\/big\]/is',
	'/\[small\]/is',
	'/\[\/small\]/is'
	);

$Replace = array
	(
	'<b>',
	'</b>',
	'<i>',
	'</i>',
	'<u>',
	'</u>',
	'<big>',
	'</big>',
	'<small>',
	'</small>'
	);

$Text = preg_replace($Find, $Replace, $Text);
return $Text;
}

$Text = "[u][b]Your message here[/u][/b]";

echo BBCode($Text);

?>

i know what y'all trying to help but all your function is working bbcode..no problem to me also...my above function also 4 working bbcode.....my problem still remain unsolve because what i explain in this topic is mistype bbcode just as show in the example above...and to prove the mistype bbcode is working prefectly is in this forum itself. If i type

 

[b ][u ]test[ /b][ /u]  --> see the result test

 

that is what i want, when user mistype the bbcode, the function automatically detect bold and underline bbcode like example above.

[Minase]

i will give you what i use right now , should be good enough no problem at those "errors"

 

function bb($bbcode){
     $bbcode = htmlentities($bbcode);
     $searchFor = array(
 '/\[b\](.*?)\[\/b\]/is', 
 '/\[i\](.*?)\[\/i\]/is', 
 '/\[url\=(.*?)\](.*?)\[\/url\]/is'
 );
     $replaceWith = array(
 '<b>$1</b>',
 '<i>$1</i>',
 '<a href="$1">$2</a>'
 );
     $html = preg_replace($searchFor, $replaceWith, $bbcode);
     return $html;
}

 

 

//edit

 

now saw -.-

why do you use [ b] and [ /b] in different arrays? * no space lol*

[pandailo]

i use space for example of "test" word result...i know there is no space using bbcode...anyway thank you for the function..i will test it out right away. tq

how to match [b ]blabla[/u] with bold bbcode <b>blabla</b>

[wildteen88]

this will require much more complex code. It is always best to parse BBCode tags in pairs and never on a singular basis. That way if users mistype a tag or place a tag where it shouldn't be your layout wont screw up.

 

You should look into adding a "Preview" area so the user can check whatever they are about to post looks correctly and apply any amendments before posting their message.
