Create a new Global Variable/constant for use in all TPL

[dianacd]

Hello!! I want to create some custom global constants that I can access from all TPL, this is some information like specific emails or external URLs that I want to put across the webpage, and in case that they change I just need to update the global constant and not all the TPLs that contain the information.

 

Is there a way to create a custom global constant?

hello, its possible using two different methods
1st is by override the front controller "classes/controller/FrontController.php" and assign your new variable in function assignGeneralPurposeVariables
by using templateVars array.

second is using hook, for this you need to make small module and use hook actionFrontControllerSetVariables

Example:

public function hookactionFrontControllerSetVariables()
{
    $new_variable = 'hello world';
    return array(
        'new_variable' => $new_variable
    );
}

And you can use this in template like this:

${modules.module_name.new_variable}

In tpl:

{$new_variable}

Thanks for your advice! I did it in the fast way, I override the FrontController and it works as expected

I was wondering, is there a way to use this variables from tpl created in Ap ShortCode? I tried but they are not recognized!

Finally I created a module to set my global variables. They are accesible only from TPL files though. Here is the code in case that it may be useful for anyone:

You can access from .tpl with {$your_variable1} ?
I am trying to send variables from a module to the invoice template. I can't get it to work, I'm doing something wrong: S
I have also tried to load these variables into $data array of "HTMLTemplateInvoice.php", trying to save from the module as smarty variable, but I also can't

edit:
By doing tests, with the override I can show the variable in the theme's .tpl, but not in the invoice tpl.
With the module method I can't, I have tested the functions; "hookDisplayPDFInvoice ()" and "hookactionFrontControllerSetVariables ()"
what am I missing?

You can access from .tpl using {$modules.mcr_global_var.your_variable}

 

To use my code you can download the only the mcr_global_var.php file and compress it into a folder and install it as a module from the BO, or just add it manually to your modules folder, then you can update the files from the modules folder with your variables anytime.

Thank you very much for your quick reply, I managed to get it to work with your module in the theme's .tpl, but I still can't get it to work in "invoice.addresses-tab.tpl".
Maybe I have to first bring the information to "HTMLTemplateInvoice.php" and load it into the $ data array?
