Hello,

I’m not a programmer. I’m trying to display a catalog view with images. Prices are only to be displayed to web users logged in to the "Retailers" group. I’m using Ditto with pagination. I have one template for normal view and a different one with the prices. What is the best way to accomplish this?

I’m using Evo 1.0.1

Any advice is much appreciated.

You can use 2 different Ditto calls

Thanks for your reply. How do I add the logic to choose between one call or the other?

I am not familiar with how you could test if a user is logged in or not but here’s how I think you should do it

create a snippet called showProducts and call it uncached

<?php
if( put here a way to check if a web user is logged in  ){
	
	$dittoOutput = $modx->runSnippet("Ditto", array('parents' => 33, 'tpl' => 'loggedInTpl'));
	
}else{

	$dittoOutput = $modx->runSnippet("Ditto", array('parents' => 33, 'tpl' => 'notLoggedInTpl'));
	
}

return $wayfinderOutput;
?>

This just the basic so you will need to modify your ditto calls

Untested but try :

<?php
if($modx->getLoginUserID()){
	
	$dittoOutput = $modx->runSnippet("Ditto", array('parents' => 33, 'tpl' => 'loggedInTpl'));
	
}else{

	$dittoOutput = $modx->runSnippet("Ditto", array('parents' => 33, 'tpl' => 'notLoggedInTpl'));
	
}

return $dittoOutput;
?>

Expanding on the above snippets, to denote specific web groups I think this would work better.

<?php
/*  showProducts
    usage: [!showProducts!]
*/

if($modx->isMemberOfWebGroup( array('Retailers'))){

	$dittoOutput = $modx->runSnippet("Ditto", array('parents' => 33, 'tpl' => 'loggedInTpl'));
	
}else{

	$dittoOutput = $modx->runSnippet("Ditto", array('parents' => 33, 'tpl' => 'notLoggedInTpl'));
	
}

return $dittoOutput;
?>

Breezer: THANK YOU, THANK YOU!

I was unsure of what arguments to pass to isMemberOfWebGroup() function.. it’s not listed on the documentation yet. It is now working as it should except for one pretty big detail: pagination. I have to call the [[showPrices]] snippet uncached to get Ditto to paginate.

I’m using a Ditto call that requires pagination... there are 72 products spread over 5 pages. The prices now toggle on and off based on my login group status BUT... I lose the pagination because Ditto needs to be called cached and I uncached my page to accommodate that.

Help! I’m sure there is someone out there who understands this better than I do.

Here is my code:

<?php
if($modx->isMemberOfWebGroup(array('Retailers'))){
  $dittoOutput = $modx->runSnippet("Ditto", array('parents' => 5, 'tpl' => 'tpl-catalog-ws', 'display' => 15, 'paginate' => 1, 'showInMenuOnly' => 0, 'paginateAlwaysShowLinks' => 1, 'orderBy' => 'menuindex asc', 'filter' => 'type,reference,2'));
} else { 
// Page visitor is not logged in as a Retailer.
   $dittoOutput = $modx->runSnippet("Ditto", array('parents' => 5, 'tpl' => 'tpl-catalog-noe', 'display' => 15, 'paginate' => 1, 'showInMenuOnly' => 0, 'paginateAlwaysShowLinks' => 1, 'orderBy' => 'menuindex asc', 'filter' => 'type,reference,2'));
}
return $dittoOutput;
?>

Again, many thanks.

SOLVED

That was my bad. I tested using [!showPrices!] instead of [[showPrices]] and that was what caused the problem. It is fixed now.

So to recap, I have the document Resource uncached, the snippet call cached and the pagination is working in Ditto as is the user group detection. Very clever. Thank you to everyone who replied! This community is great.
