 Snippet name: ShowMetaData
 Short Desc: Displays db table metadata
 Version: 0.5
 Author: Bob Ray
 Date: May 7, 2007
::::::::::::::::::::::::::::::::::::::::
Description:
 Shows the metadata (table structure) of a table in the MODx database.
 I wrote this as a quick and dirty way to look at the structure of any 
 table in the database. 

 I'm hoping to create a generic snippet that will
 allow front-end editing of tables in the database.
 I did this as a first step but thought it might be
 useful, or at least instructive, for others.


::::::::::::::::::::::::::::::::::::::::
Example Usage:
    [!ShowMetaData? &tableName=`modx_active_users`!]
    
    The table name is just the name of the database
    table you want to see the structure of.

    Note: $tableName is a required parameter and must be
          surrounded by backticks, not single quotes.


    To use this snippet, just paste this code (minus the php tags)
    into a new snippet called ShowMetaData. Then create a new document
    with the snippet call: [!ShowMetaData? &tableName='name of your table'!]
::::::::::::::::::::::::::::::::::::::::
*/


//Check for $tableName parameter

if (!isset($tableName)) {  
    
    return 'Error: No table name in Snippet call.<br>
    Example: [!showMetaData? &tableName=`mydbtable`!]<br>';
}

// Get the metadata from the MODx db

$structureArray = $modx->db->gettablemetadata($tableName);

echo '<h2>Structure of table: ',$tableName,'</h2>';

// Raw view of structure
// Comment out the following two lines if you don't want raw view

echo '<h3>Raw View</h3>';
print_r(array_values($structureArray)); //prints raw table structure



echo '<h3>Prettified View</h3>';

reset($structureArray); //may not be necessary but can't hurt

while (list($key, $val) = each($structureArray)) // walk through fields
  {
  echo "<b>$key</b>";echo "<br />";   // field header

     while (list ($newkey, $newval) = each($val)) { //walk through each field's specifiers
        echo "<span style='color:#ff0000;'>   <b>$newkey:</b></span> $newval";
        echo "<br />";
     }
  
  echo '<p> </p>';  //separate the fields
  }
  echo "Note: If Null: is not YES then field doesn't allow null values.";
?>

<?php
// get the current time and apply the offset
$timestamp = time() + date_default_timezone_set('America/Los_Angeles');
// Set the current year
$today_year = date('Y',$timestamp);

print $today_year;
?>

$output = date(Y);

#	Snippet Name:	Logout Manager Links
#	Written By:		Jay Gilmore (smashingred)
#	Created:		19-12-2007
#	Updated:		12-12-2007
# 	Notes:			Based on Adam Crownoble's LoginLogoutLink (8/3/2005) 
#					and QuickEdit. 
#	Description:	Generates "Logout" and "Go to Manager" Links.
#	Version:		0.2
#
#::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::
#	Changes
#
#	Version: 0.2 - 07-01-2008
#	-added ability to use a chunk to customise output with placeholders.
#
#
#:::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::
#	Usage
#	
#	Simple (No Params/Default)
#
#	[!LogoutManagerLinks!]
#
#	With optional user template
#	
#	[!LogoutManagerLinks? &tpl=`chunkname`!]
#
#	Where chunkname is the name of your chunk that contains a template
#	with the required placeholders [+loURL+] and [+mgrURL+]
#
#	1. Create a chunk called "lmlTml" (or whatever you want) and place your link template as below:
#		<a href="[+loURL+]" title="Logout Link Title">Logout Now!</a><br/>
#		<a href="[+$mgrURL+]" title="Go to Manager Title">Go to Manager Now!</a>
#	2. Place your call in your page as below:
#		[!LogoutManagerLinks? &tpl=`lmlTpl`!] (or using whatever you named the chunk)
#
#	Important!: Do not place the chunk call in the document as it will be visible to all users.
#
#
#:::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::
#	Parameters
#		
#	&lo_link_name - Link text to appear on page. (String)[Optional] Default: Logout
#	&lo_link_title - Link title for the link to appear in <a> element as title value.(String)[Optional] Default: Click here to logout.
#	&lo_doc_id - Document to send user to on logout.(String)[Optional] Default: current document.
#	&mgr_link_name - Link text to appear on page.(String)[Optional] Default: Go to Manager.
#	&mgr_link_title - Link title for the link to appear in <a> element as title value.(String)[Optional] Default: Click here to go to manager.
#	&tpl - Name of chunk to use for ouput. (String)[Optional]
#		
#::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::
#	TODO
#	- Clean Code
#	- Add ability to use chunk id, @code:, @file:
#


// Link Titles and Names

# Logout Link Name
$lo_link_name = isset($lo_link_name) ? $lo_link_name : 'Logout';

#Logout Link Title
$lo_link_title = isset($lo_link_title) ? $lo_link_title : 'Click here to logout';

# Manager Link Name
$mgr_link_name = isset($mgr_link_name) ? $mgr_link_name : 'Go to Manager';

# Manager Link Title
$mgr_link_title = isset($mgr_link_title) ? $mgr_link_title :'Click here to go to the manager';

# Document to go to on logout
$lo_doc_id = isset($lo_doc_id) ? $lo_doc_id : $modx->documentIdentifier;

# Generates Logout URL
$loURL= "index.php?id={$lo_doc_id}&LML_logout=logout";

# User template chunk to output 
$tpl = isset($tpl) ? $tpl : ''; 

#:::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::
# Checks to see if the optional template chunk exists and outputs it
$userTpl = $modx->getChunk($tpl);
	


# Generates Manager URL
$mgrURL = $modx->getManagerPath();
$lml_logout= (isset($_GET['LML_logout'])? $_GET['LML_logout']: '');

#:::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::
# Default Template to be used if no user template exists.

$defaultTpl = <<<EOD
<a href="{$loURL}" title="$lo_link_title">$lo_link_name</a> | <a href="{$mgrURL}" title="$mgr_link_title">$mgr_link_name</a>
EOD;

#:::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::
# Placeholders Stuff
		$pholders = array('[+loURL+]','[+mgrURL+]');
		$swap = array("$loURL", "$mgrURL");
		$tplOutput = str_replace($pholders, $swap, $userTpl);
		
#:::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::
# The Logic

//Checks to see if user is logged in as manager.
if($_SESSION['mgrValidated']){
	
	//Checks to see if the logout link has been clicked
    if($lml_logout == 'logout') {
    	//If logout link clicked is true then clear the Manager session and end the snippet.
     $_SESSION = array();
     } 
     	//If User Template exists return its contents
     elseif ($userTpl){
                return $tplOutput;
        }
     else
     {
     	//Otherwise return the default template
     return $defaultTpl;
     }
 } 
 else 
{
 	//End the script

 * **************************
 * Snippet: prevtv V.1.0
 * By: sharkbait / @kunane
 * Date: Nov 2009
 * inspired & borrowed some parts of: PrevJumpNextXHTML Snippet
 * from the version modified by PMS
 * **************************
 
installation:
1. create a new snippet "prevtv" and copy this code into the  Snippet code-field
2 in your template call the snippet like this: [!prevtv? &direction=`1` &tvname=`yourtvname` !]

&direction=`1` will return the value of the TV from the previous ressource
&direction=`2` will return the value of the TV from the next ressource

enter the name of the TV you want to retrieve the value
&tvname=`yourtvname`

enter the text you want to be displayed if there's no image (ressource prev. to the first / next to the last) - leave it empty if you want no text to be displayed
&text=`no image`

currently a text will be displayed "no image available" for the previous ressource of the first item and for
the next ressource of the last item. If you don't want do display a value, just delete the string in line 72 & 89

the order of the TVs  currently reflects the defauld order of Wayfinder
 
 sorry for the ugly code - #itsmyfirstsnippet :)
