[SOLVED] BBCode help? =)

[Twister1004]

Hey everyone! I have another question, still with my PHP skills still in development =)

 

Objective:

I am trying to make a BBCode for a webpage so it will just register it when it sees it. More like Using a Smiley and not the "=P" stuff. This is not for forums. This is for like a little comments on a users profile.

 

Issue:

I don't know exactly how to go about this. I was told I was doing it wrong, which now I believe I am, however, I don't know of another way. Either I'm too stupid or I've just never used it. (I've not done anything like this!!!!!)

 

So without further due, here is the original code I wrote,

<?php
error_reporting(E_ALL);
if("[b]" || "[b]"){
echo "<b>";
} elseif("[/b]" || "[/b]"){
echo "</b>";
} elseif("[i]" || "[i]"){
echo "<i>";
} elseif("[/i]" || "[/i]"){
echo "</i>";
} elseif("[u]" || "[u]"){
echo "<u>";
} elseif("[/u]" || "[/u]"){
echo "</u>";
} elseif("
[center]"){
echo "<center>";
} elseif("[/center]
"){
echo "</center>";
} elseif("
[right]"){
echo "<span align=\"right\">";
} elseif("[/right]
"){
echo "</span>";
} elseif("
[left]"){
echo "<span align=\"left\">";
} elseif("[/left]
"){
echo "</span>";
} elseif("[img]http://"){
echo "<img src=\"";
} elseif("[/img]"){
echo "\" alt=\"Image\"";
} elseif("[url=http://"){
echo "<a href=\"$\">";
} elseif("]"){
echo "<a href=\"$\">";
} elseif("[/url]"){
echo "</a>";
} elseif("[font]"){
echo "<font face=\"";
} elseif("[/font]"){
echo "\"</font>";
} elseif("[color]"){
echo "<font color=\"";
} elseif("[/color]"){
echo "\"</font>";
} elseif("" || "=)"){
echo "<img src=\"parser/smileys/smile.gif\" alt=\"sad\"";
} elseif("" || "=P"){
echo "<img src=\"parser/smileys/tounge.gif\" alt=\"sad\"";
} elseif(":/" || "=/"){
echo "<img src=\"parser/smileys/bored.gif\" alt=\"sad\"";
} elseif(""){
echo "<img src=\"parser/smileys/lol.gif\" alt=\"sad\"";
} elseif("" || ">=("){
echo "<img src=\"parser/smileys/mad.gif\" alt=\"sad\"";
} elseif("" || "=O"){
echo "<img src=\"parser/smileys/smile.gif\" alt=\"sad\"";
} elseif("" || "=("){
echo "<img src=\"parser/smileys/sad.gif\" alt=\"sad\"";
} elseif(":wink:" || "^_~" || "" || ""){
echo "<img src=\"parser/smileys/wink.gif\" alt=\"wink\"";
}
?>

 

 

Any help would be greatly appreciated!

Don't take this the wrong way, but you're doing that entirely wrongly.

 

 

 

When ever you do if(condition), the yes branch of the if tree only executes if the "condition" evaluates to true.

 

 

So essentially, you're doing:

 

if("[b]" == true) {
    echo '<b>';
}

 

 

You need to be replacing the codes inside of strings though.

 

 

http://php.net/str_replace.

 

 

For example, to replace [ b] (ignore the space) with <b>, you could do:

 

$content = "Look at the [b]bold word.[/b]";
$content = str_replace(array('[b]', '[/b]'), array('<b>', '</b>'), $content);

 

 

Or, you could go the regexp route (which you will probably want to avoid unless you have to use if you're new to PHP.

 

$content = "Look at the [b]bold word.[/b]";
$content = preg_replace('~[b](.*?)[/b]~', '<b>\1</b>', $content);

No offense taken Corbin. I'm not easily offended when I'm trying to learn something new.

 

So, by how this is setup (Really confuzzling to me, but still learning its structor), there is a loop going on, and it is named $c.

 

So to do what your saying I need to do, but I think I get it, please correct me if I'm wrong,

 

$code = str_replace("[-b]", "<b>", "bold");

 

The first one would be if it finds it ([-b]) then it will replace it with <b>. Then the "bold" is its name?

[corbin]

str_replace works like this:

 

 

mixed str_replace ( mixed $search , mixed $replace , mixed $subject [, int &$count ] )

 

 

 

The first param is what to replace, the second param is what to replace it with, and the third param is the input.

 

 

So, for example:

 

echo str_replace("world", "Twister1004", "Hello world!");

 

 

Would output "Hello Twister1004!"

[Twister1004]

OMG CORBIN I LOVE YOU!!! <3

 

*IS EXCITED~!*

 

I actually get it now =D!!!!

 

str_replace("hey!", "Go die!", "Hey! Tyler!");

 

So let me get this clear and make sure!

 

1st parameter ("hey!") Is what it is looking for.

2nd parameter ("Go Die!") is what it will replace once it finds the "hey!".

3rd parameter ("Hey! Tyler!") is the input and will look in this parameter and look for the "hey!" and then it will replace it?

 

 

Final Clear up, This is my final answer for $50,000!!! IS IT CORRECT?! *Waits for the answer!*

[corbin]

Yup.

 

 

Except it's case sensitive.  str_ireplace is the case-insensitive version.

 

;p

[Twister1004]

Kay kay!!!! I love you <3333333 *hugs tightly*

 

 

Thank you =)

[corbin]

No problem.

[Twister1004]

ok,

 

Well, I just wrote a few codes, but they doesn't wanna work.

 

Any ideas what I did wrongly? xD

 

str_replace(array("[b]", "[/b]"), array("<b>", "</b>"), $c['comment']);
str_replace(array("[i]", "[/i]"), array("<i>", "</i>"), $c['comment']);
str_replace(array("[u]", "[/u]"), array("<u>", "</u>"), $c['comment']);
str_replace(array("
[center]", "[/center]
"), array("<center>", "</center>"), $c['comment']);
str_replace(array("
[right]", "[/right]
"), array("<span align=\"right\">", "</span>"), $c['comment']);
str_replace(array("
[left]", "[/left]
"), array("<span align=\"left\">", "</span>"), $c['comment']);
str_replace(array("[img=http://", "]"), array("<img src = \" \">", "</img>"), $c['comment']);
str_replace(array("[url=http://", "]", "[/url]"), array("<a href=\"\">","</a>"), $c['comment']);
str_replace(array("[color]", "[/color]"), array("<font color=\"\">", "</font>"), $c['comment']);
str_replace(array("[font]", "[/font]"), array("<font face=\"\">", "</font>"), $c['comment']);

Now on every page you going to use bbcode. Put:

 

include('bbcode_engine.php');

 

at the top of your page.

 

Then to display this:

 

$bbc->bbcode_parse($output);

 

now put this above the above code:

 

$output = '[b]Look im bold?[/b]
[i]Im italicalized[/i]

[center]Centered?[/center]

[u]Not centered but underlined[/u]';

 

All the spaces are already included and there for you do not need to add <br>.

 

Enjoy

Thank you for the script from microsoft, however, I wish to try and make one.

 

[Twister1004]

I fixed, I just needed to put a variable there!

 

 

Ok, nect question, how would I be able to put [-color=green] and make it green? I've not figured it out yet.

[corbin]

If you're going to make a full out BBCode system, you should stop now, learn some basic regular expressions and then restart.

 

This one is easy with regular expressions:

 

$content = preg_replace('~\{1,6})|black|red|green|blue|purple|yellow)](.*?)\[\/color\]~', '<font style="color: \1;">\2</font>');

 

But without regular expressions....  You would have to find all instances of [-color in the text, then capture the part after the =, then find the part in between [-color] and [ /color]

[Twister1004]

Well, the main one I wanted to do was color and urls. But, anyways, Thanks for the help again

[corbin]

No problem again ;p.
