trying to implement BBcode

Gnuff

Hello!

I'm making a site where users can post news, and I'm trying to implement bbcode to make it simple for all the users, I'm not very experienced with php, so I hope someone can help me.

firstly I have have the form script.

<?php include("header.php"); ?>
<br><h3>New news article</h3>
<div id="addnews">
<br><br>
<form method="post" action="/lodge/addnewsprocess.php">
Title:<br><input type="Text" name="title" cols=30><br>
Content:<br><textarea name="content" rows=30 cols=55></textarea>
<br><input type="submit" value="Submit" name="register">
</form>
</div>
<?php include("footer.php"); ?>

Then the processing to the database

<?php
ob_start();
session_start();
?>
<?php include("header.php"); ?>
<?php
//variables from the form
$title = $_POST['title'];
$content = $_POST['content'];
$date = date("F j Y");
$user = $_SESSION['username']; 
//check that user have filled in everything
$errors = 0;
$emessage = "<center>Sorry, we enounctered the following errors when processing your article:<br /><ul>";
if(empty($title) || empty($content))
{
 $errors = 1;
 $emessage .= "<li>Sorry, you must fill in <strong>all</strong> fields.  Please go back and try again.</li>";
}
//if the user made errors, show messages
if($errors != 0)
{
 $emessage .= "</font></center>";
 die("$emessage");
}

//perform query, inseting user submitted data
mysql_query("INSERT INTO news (title, content, date, user) VALUES ('$title', '$content', '$date', '$user')") or die(mysql_error());
//message if everything went well.
echo("<center><br><br><br>Thanks for posting.  Click <a href=\"/lodge/mainpage.php\">here</a> to return to the member's page.</font></center>");
ob_end_flush();
?>
<?php include("footer.php"); ?>

I have downloaded a bbcode script from http://www.bbcode.org/implementations.php

<?php

function BBCode($Text) {

	// Replace any html brackets with HTML Entities to prevent executing HTML or script

	return $Text;
}
?>

How can I modify my scripts to make this work? I've try'd some things, but nothing seem to work.

Well the easiest way to do this (and its simple) is the str_replace function.

Heres an example

$content = $_POST['content'];

$bbcode = array(":)", ":(" , ":D", ":p"); // separate with commas.

$newbbcode = array("<img src=\"./smile.gif\">", "<img src=\"./frown.gif\">", "<img src=\"./big-smile.gif\">", "<img src=\"./tongue.gif\">");

$content =  str_replace($bbcode, $newbbcode, $content);

echo $content;

the main thing to remember is that the "$bbcode" has to line up with the "$newbbcode"

thank you for your reply!
But what should I do, what script should I modify and so on?

thank you

knowj

require_once 'includes/bbcodeinclude.php';
$text = "[url]http://www.myurl.com[/url]";
echo BBCode($text);

Also get rid of the <center> tag its been depreciated for years

Hi, I've been working with your code and I've modified it so it will work a little easier (for me atleast).

Hope this helps!

<?php 
ob_start(); 
session_start(); 
?> 
<?php include("header.php"); ?> 
<?php 
//variables from the form 
$title = $_POST['title']; 
$content = $_POST['content']; 
$date = date("F j Y"); 
$user = $_SESSION['username']; 

// Starts the BBcode.
$bbcode = array("[u]", "[U]", "[/u]", "[/U]", "[i]", "[I]", "[/i]", "[/I]", "[b]", "[B]", "[/b]", "[/B]", ":)", ":(" , ":D", ":p"); // separate with commas. 

$newbbcode = array("<u>", "<u>", "</u>", "</u>", "<i>", "<i>", "</i>", "</i>", "<b>", "<b>", "</b>", "</b>", "<img src=\"./smile.gif\">", "<img src=\"./frown.gif\">", "<img src=\"./big-smile.gif\">", "<img src=\"./tongue.gif\">"); 

$content =  str_replace($bbcode, $newbbcode, $content);

// this is something that I'm including to help you from getting hacked.

// to block more words just add them in quotes and seperate with commas.
$badWords = array("<?php", "<?PHP", "?>");

foreach($badWords AS $v) {
	// Replaces the words to nothing.
	$content = str_replace($v, "", $content);
	$title = str_replace($v, "", $content);
}

//check that user have filled in everything 
if(!$title && !$content) {
	$error = "<li>Sorry, you must fill in <strong>all</strong> fields.  Please go back and try again.</li>";
}else if(!$title) {
	$error = "<li>Sorry, you must fill in the field <b>Title</b>. Please go back and try again.</li>";
}else if(!$content) {
	$error = "<li>Sorry, you must fill in the field <b>Content</b>. Please go back and try again.</li>";
}

// This counts the errors and if there was more than one then echo out the error.
if(count($error) > 0) {
	echo $error;
// If there wasn't an error than insert into the table.
}else {
//perform query, inseting user submitted data 
mysql_query("INSERT INTO news (title, content, date, user) VALUES ('$title', '$content', '$date', '$user')") or die(mysql_error()); 
//message if everything went well. 
echo("<center><br><br><br>Thanks for posting.  Click <a href=\"/lodge/mainpage.php\">here</a> to return to the member's page.</font></center>");	
}

ob_end_flush(); 
?> 
<?php include("footer.php"); ?>

Thank you! This works like a charm!
I understand more now!

This is a great forum!

While the script is actually functioning, I'm trying to add "", "[/img]); // separate with commas.

$newbbcode = array("", "", "", "", "", "", "", "", "", "", "", "", "<img src=\"./smile.gif\">", "<img src=\"./frown.gif\">", "<img src=\"./big-smile.gif\">", "<img src=\"./tongue.gif\">", "<img src="", "<img src="", "" width="500px">", "" width="500px">"); [/code]

Try this

Oh yeah, the reason I did double was because one one one is lowercase and the other is uppercase. (but the forum made them all to lower 🙁)

<?php

$content = "[url]http://www.google.com[/url] - [img]http://www.brwpages.com/images/logo.png[/img] = [url=http://www.brwpages.com]BRWPages[/url]";

$bbcode = array('/\[url\=(.*?)\](.*?)\[\/url\]/is', '/\[img](.*?)\[\/img\]/is', '/\[url](.*?)\[\/url\]/is');

$newbbcode = array('<a href="$1">$2</a>', '<img src="$1">', '<a href="$1">$1</a>');

$content = preg_replace($bbcode, $newbbcode, $content);

echo $content;

?>

Your problem was one. You forgot to add your last quote in bbcode variable.

and two you have to add a \ before every double quote in the quotes. Like this

$bbcode = array("<a href=\"http://www.google.com\">Google</a>", "<a href=\"http://www.someurl.com\">SomeUrl</a>"); // ect.

You may also want to look at the PHP [man]bbcode[/man] extension, or the PEAR HTTP_BBCodeParser package.
