codebox

[james182]

i need to create a code box that will display information and code like this.

information goes here

<?php function codeView(){
echo "test";
}
?>codebox initiated

the above is my goal.

this is what i have so far, but won't allow for

 [code] tags or text either side of area..
[code=php]<?php


$code = '<?php
/* COMMENT */
define("TEST","poo");

function checkPass($login, $password) {
	/*
	Password checking function:
	This is a simple function that takes the $login name and
	$password that a user submits in a form and checks that a
	row exists in the database where:
	*/

global $link;

$query = "SELECT * FROM tbl_users WHERE user_username = \'$login\' AND user_password = \'$password\' ";
$result = mysql_query($query, $link) or die("checkPass fatal error: ".mysql_error());

// Check exactly one row is found:
if(mysql_num_rows($result) == 1) {
	$row = mysql_fetch_array($result);
	return $row;
}
//Bad Login:
return false;
}

?>';


printCode($code, '1');

/*
$content = secure($code);
function secure($code) {
	$code = strip_tags($code);
	$code = htmlspecialchars($code);

[dagon]

have you looked at:

highlight_string() and highlight_file()

[james182]

so is this phpbb do it, as thats my goal.

text copy here then adding code.
['code']
<?php
echo "my code";
?>
['/code']

the above should look like this:

text copy here then adding code.

<?php
echo "my code";
?>

This is how you do it. This code is minimal, there are some sercurity issues you need to deal with. but, run this and you will get the idea.

<style>
.code {
  border-width: 1px;
  border-style: inset;
  padding: 8px;
  background-color: #FFFFDD;
}
.quote {
  border-width: 1px;
  border-style: inset;
  padding: 8px;
  background-color: #DDDDFF;
}
.link {
  border-width: 1px;
  border-style: inset;
  padding: 8px;
  background-color: #DDFFDD;
}
</style>

<?php

function ExtractTag($haystack, $tag, &$start, &$middle, &$end)
{
  $k = strlen($tag) + 2;
  if(($i = strpos($haystack, "[$tag]")) !== false)
  {
    $j = strpos($haystack, "[/$tag]", $i);
    if($j === false) $j = strlen($s);
    $start = substr($haystack, 0, $i);
    $middle = trim(substr($haystack, $i + $k, ($j - $i) - $k));
    $end = substr($haystack, $j + $k + 1);
    return true;
  }
  return false;
}

function EncodeCode($s)
{
  return "Code:<div class=code>" . highlight_string($s, true) . "</div>";
}

function EncodeQuote($s)
{
  return "Quote:<div class=quote>" . nl2br($s) . "</div>";
}

function EncodeLink($s)
{
  return "Link:<div class=link><a href='$s'>$s</a></div>";
}

function EncodeText($s)
{
  return "<div class=text>" . nl2br($s) . "</div>";
}

function EncodePost($s)
{
  if(ExtractTag($s, "code", $start, $middle, $end))
    $s = EncodePost($start) . EncodeCode($middle) . EncodePost($end);
  else
    if(ExtractTag($s, "quote", $start, $middle, $end))
      $s = EncodePost($start) . EncodeQuote($middle) . EncodePost($end);
  else
    if(ExtractTag($s, "link", $start, $middle, $end))
      $s = EncodePost($start) . EncodeLink($middle) . EncodePost($end);
  else
    $s = EncodeText($s);
  return $s;
}

echo EncodePost("This is my post
[code]
<?php
echo \"my code\";
?>

Hello, this is more of my post and here is a quote,

Man who stand on toilet is high on pot

[link]http://www.buzzphp.com[/link]");
?>[/code]

[james182]

thanks for that.
So is this how phpbb do it?

[Weedpacket]

You could look at the phpbb source code to find out....

[james182]

thanks again for the code.

one question why does it add slash like below ( \" )

define("TEST\",\"poo\"); 

and can i remove it?

[james182]

below is the entire code, my question is how do i get the hightlighting to work properly. I think i need to remove \" but not sure how.
