Change template on the fly

Hi all,

I’m looking for a way to change the template on the fly. I’m building serval sites witch need a jquery-colorbox to view general conditions for example. But in a colorbox view I don’t want to see the whole site design, I only want the text view.

I was thinking to add a get parameter like ...html?popup=true and create a plugin to catch this and set the template temporary to another template id wich is empty. In this way all pages are viewable in the colorbox. The colorbox pages are somewhere in the menu of the site so the page couldn’t have the template set. But how he handles cache etc. I don’t know.

Maybe one you have done this before or had a better idea?

Regards, Bert

I use this snippet.

named it ’ajaxSwitch’

<?php

$output = '';

$properties =& $scriptProperties;
$properties['ajaxid'] = isset($_REQUEST['ajaxid']) ? $_REQUEST['ajaxid'] : 'none';
$properties['cache'] = isset($cache) ? (boolean) $cache : (boolean) $modx->getOption('cache_resource', $properties, false);
$properties[xPDO::OPT_CACHE_KEY] = $modx->getOption('cache_resource_key', $properties, 'default');
$properties[xPDO::OPT_CACHE_HANDLER] = $modx->getOption('cache_resource_handler', $properties, 'xPDOFileCache');
$properties[xPDO::OPT_CACHE_EXPIRES] = (integer) $modx->getOption(xPDO::OPT_CACHE_EXPIRES, $properties, 0);

if ($properties['cache']) {
    $properties['cachePageKey'] = $modx->resource->getCacheKey() . '/' . $properties['ajaxid'] . '/' . md5(implode('', $modx->request->getParameters()));
    $properties['cacheOptions'] = array(
        xPDO::OPT_CACHE_KEY => $properties[xPDO::OPT_CACHE_KEY],
        xPDO::OPT_CACHE_HANDLER => $properties[xPDO::OPT_CACHE_HANDLER],
        xPDO::OPT_CACHE_EXPIRES => $properties[xPDO::OPT_CACHE_EXPIRES],
    );
}
$cached = false;
if ($properties['cache']) {
    if ($modx->getCacheManager()) {
        $cached = $modx->cacheManager->get($properties['cachePageKey'], $properties['cacheOptions']);
    }
}
if (empty($cached) || !isset($cached['properties']) || !isset($cached['output'])) {

if ($properties['ajaxid'] == 'none'){
    $output = $modx->getChunk($defaultChunk);      
}else{
    $output = $modx->getChunk($ajaxChunk,$_REQUEST);  
}



    if ($properties['cache'] && $modx->getCacheManager()) {
        $cached = array('properties' => $properties, 'output' => $output);
        $modx->cacheManager->set($properties['cachePageKey'], $cached, $properties[xPDO::OPT_CACHE_EXPIRES], $properties['cacheOptions']);
    }    

} else {
    $properties = $cached['properties'];
    $output = $cached['output'];
}


return $output;

in my template i put something like that:

[[!ajaxSwitch? 
&ajaxChunk=`ajaxTemplate` 
&defaultChunk=`baseTemplate`
&cache=`1`
]]

than I create two chunks, one for default and one for ajax-calls.
On my ajax-chunk I can place different snippets, which return output for ajaxcalls with different ajaxids.
This way I can call different cached parts of my page by ajax with &ajaxid=`sidebox` or &ajaxid=`slider` in the URL.

I did this by adding the following as my only line in the template

[[$[[!gallerySwitch]]]]

this snippet checks to see if the get parameter exists to decide which chunk to call

<?php
if(isset($_GET['popup']) && $_GET['popup'] == 1) {
	$template = 'galleryHighslide';
} else {
	$template = 'galleryStandardPage';
}
return $template;

The chunk ’galleryStandardPage’ then cross references other chunks that are the site building blocks e.g.

[[$header1]]
[[$header2]]
[[*content]]
[[$footer1]]
[[$footer2]]

and the chunk ’galleryHighslide’ is just

[[$header3]]
[[*content]]
[[$footer3]]

you know, this is completly unchached, then.

Thanks for this guys!

Uncached.. Could this be cached also or do you need to write your own mechanism for that?

this does the same as my snippet above, but my snippet can cache the results.

you would use it this way in this case:

[[!ajaxSwitch? 
&ajaxChunk=`galleryHighslide` 
&defaultChunk=`galleryStandardPage`
&cache=`1`
]]

send with your URL a &ajaxid=something

Hi Bruno

I wasn’t too worried about caching, I just needed a solution

But you’re solution looks better if it achieves the same AND caches.

Not sure how your code decides to use ajaxChunk - how do I send it the parameter?

[[!ajaxSwitch? 
&ajaxChunk=`galleryHighslide` 
&defaultChunk=`galleryStandardPage`
&cache=`1`
]]

just send with your ajax-request

&ajaxid=something

I use the ajaxid to get different parts from my ajax-chunk into the frontpage.
