How to transfer a variable from a Joomla template to FC template or module? was created by lipatovroman

Hello!
For example I created variable in Protostar template in file

/templates/protostar/index.php

How to transfer a variable from a Joomla template to FC template or module?

for example in

/modules/mod_flexitagcloud/tmpl/default.php

Explain.

I use some code in template like:

Code:

$app  = JFactory::getApplication();
$menu = $app->getMenu()->getActive()->link;
$menu = JRoute::_($menu);

	 if ( strpos($menu, '/bmw') !==false) {
		 $modcolor = " bmwstyle ";
	 }	 
	 elseif ( strpos($menu, '/audi') !==false) {	
	     $modcolor = " audistyle ";	 
	 }	 
	  elseif ( strpos($menu, '/mercedes') !==false) {
	     $modcolor = " mercedesstyle ";		 
	 }
	   elseif ( strpos($menu, '/peugeot') !==false) {
	     $modcolor = " peugeotstyle ";		 
	 }
	 else $modcolor = false;

So, I want to make it once in template and then to get $modcolor variable in several modules and some FC fields.

Of course, I can duplicate this code (above) several times in modules and FC fields.
But I'm afraid this will slow down the site.
Thanks.

Hello you can use Joomla session

Set variable

Code:

$app = JFactory::getApplication();
$option = $app->input->getCmd('option');
$myvarname = 'some_calculated_value';
$app->setUserState( $option . '.myvarname' , $myvarname); 

Read variable

Code:

$app = JFactory::getApplication();
$option = $app->input->getCmd('option');
$myvarname = $app->getUserState( $option . '.myvarname'); 

Just the code that sets variable should run before the code that reads it

Thank you.
It will be faster than, my code above running 3 times on a page loading?

the code that you posted costs almost zero time

Code:

$app  = JFactory::getApplication();  // zerp
$menu = $app->getMenu()->getActive()->link; // almost zero because the active item has already been calculated and cached by system
$menu = JRoute::_($menu);  // almost zero because the link include Item id
// ... then a few strpos almost zero time again

you can measure it like this

Code:

$start_microtime = microtime(true);

// ... ADD your code here

$time_diff_micro_seconds = round(1000000 * 10 * (microtime(true) - $start_microtime)) / 10;

echo '<h2>Costed ' . sprintf(" %.2f seconds", $time_diff_micro_seconds/1000000) . ' </h2>';

Hmmm...

I inserted Set variable code in Protostar index.php

and Read variable code in components/com_flexicontent/templates/downloads/item.php

It works, but only after refreshing page.

When I open page first time - $myvarname is empty, because cookies are still empty.

So, when crawlers scaning site (which not use cookies) will not see $myvarname value on page.

Hello

if it is empty then it means that the code that uses it is executed before the code that sets it

you are suppoed to creation on the first place that is used
