This tutorial will show you how to return data from a column you've created and parse template conditionals.

PHP Code:


			
<?php



// ######################## SET PHP ENVIRONMENT ###########################

error_reporting(E_ALL & ~E_NOTICE);



// ##################### DEFINE IMPORTANT CONSTANTS #######################

define('THIS_SCRIPT', 'my_script'); 



// #################### PRE-CACHE TEMPLATES AND DATA ######################

// get special phrase groups

$phrasegroups = array();



// get special data templates from the datastore

$specialtemplates = array();



// pre-cache templates used by all actions

$globaltemplates = array();



// pre-cache templates used by specific actions

$actiontemplates = array();



// ########################## REQUIRE BACK-END ############################

require_once('./global.php');



//You must include this in order to parse HTML based conditionals 

require_once(DIR . '/includes/adminfunctions_template.php');

// ########################################################################

// ######################### START MAIN SCRIPT ############################

// ########################################################################



//First we need to query the table.

$sql = $db->query_first("SELECT * FROM " . TABLE_PREFIX . "my_table WHERE column = 'X' ");



//Now we need to convert the HTML based conditionals to PHP based 

eval('$done = "' . compile_template($sql['my_field']) . '" ;');



//Print the results to the screen

eval('print_output("' . fetch_template('my template') . '");');



?>

For sake of this article let's say "$sql['my_field']" contains the following

HTML Code:

<if condition="is_member_of($bbuseruserinfo, 12)">
To access the arcade click on "Links" to access the menu.<br />
Within the menu choose "Arcade".
<else />
<if condition="!is_member_of($bbuseruserinfo, 12)">
To access the arcade you need a minimum of 1000 posts. Currently you only have $bbuserinfo[posts]
</if>
</if>

You'll need to take the variable "$done" and place it in "my_template".

HTML Code:

$stylevar[htmldoctype]
<html dir="$stylevar[textdirection]" lang="$stylevar[languagecode]">
<head>
$headinclude
<title>$vboptions[bbtitle]</title>
</head>
<body>

$header
$navbar

<table class="tborder" cellpadding="$stylevar[cellpadding]" cellspacing="$stylevar[cellspacing]" border="0" width="100%" 

align="center">
<tr>
<td class="tcat">My Custom Page Title</td>
</tr>
<tr>
<td class="alt1">$done</td>
</tr>
</table>

$footer
</body>
</html>

I have tested the security and it returns dangerous code as plain text. This means that no one can perform mischievous actions towards your forums.

Can you explain in detail WHY you would want to create such a tool?

Many members won't understand; therefore, limiting the help that you are trying to achieve.

I'm sorry Princeton but I'm not good at explaining how stuff works.

I would have never thought of using a template conditinal in that manner, very interesting. Thanks!

I had no idea this could be done, which is ridiculous since it's perfectly obvious now it's been pointed out. Thank you, I've made good use of it.
