[SOLVED] Inserting php in a custom module

[pedrogon]

Hi, I want to use insert some php code (this: http://www.finalwebsites.com/forums/topic/how-to-use-maxmind-geoip-for-websites#post-1591) in order to show the result in the right column of my site.

 

I've read quite a bit about this and I got the impression that the cleanest solution is to create a custom module (please, tell me if I'm wrong and there is a better solution).

 

I've created my custom module following the instructions of http://www.technoreply.com/how-to-create-a-prestashop-1-5-module/ and a little bit of http://doc.prestashop.com/display/PS15/Creating+a+PrestaShop+module.

 

It works OK for showing some text (either putting the text directly in the tpl file or putting something like 'mymodule_message' => $this->l('example text') in mymodule.php).

 

But I don't want show a "fixed" text message, I want to insert php code and show the result of that code. I don't have any idea of where shoud I put the php code to make it work.

 

Now the "interesting" part of mymodule.php says:

public function hookDisplayLeftColumn()
{
$this->context->smarty->assign(array(
'placement' => 'left',
'my_module_message' => $this->l('example text') // Do not forget to enclose your strings in the l() translation method
));

return $this->display(__FILE__, 'left.tpl');
}

Should I put the php code in this part, create a new php file and call it from here or what?

 

Thanks for your help and sorry for asking noobie questions, but that's what I am right now (I don't know much about prestashop or php, but willing to learn)...

if you want a variable text in my_module_message

 

then before assiging the smart array variable

 

add php code above this assign and withing the function to set my_module_message = ($variable_message)

 

for example

if ($x == foo)

   $variable_message = 'equal to foo';

else

  $variable_message = 'not equal foo';

then assign:

'my_module_message' => $variable_message,

I hope I understood your question and helped accordingly.

Yes you can put the code there, or you can call some external function and then assign the result in the tpl which will be rendered into the HOOK_LEFT_COLUMN

Thanks a lot for your quick responses!

 

I've tried El Patron's solution and works like a charm.

 

Enrique, could you please give me an example of what would be the code for calling a external function and assigning it? (or a link to the relevant documentation)

jajaja..two Spanish speakers...yo soy malo hablo espanol...but I have houses in Colombia and Spain.

 

as for your question, here is an example of obtaining a price

 

where Tools is the classand  displayPrice is the funciton within Tools

			$this->smarty->assign(array(
				'total_to_pay' => Tools::displayPrice($params['total_to_pay'], $params['currencyObj'], false),

[Enrique Gómez]

I was about to put a similar example.... The Autoload class makes available the php code in /classes and /controllers folder (and override folders) so you have available the utility static methods of Tools class. But you can also import your classes with for example

require_once( _PS_MODULE_DIR_ . 'your_module_folder/your_module_subfolder/init.php');

Jajaja, good one Enrique. Did you knew that they have registered it as a trademark and opened an online store only for products with this phrase!!?? http://www.antena3.com/noticias/sociedad/hija-exalcalde-madrid-solicita-registrar-relaxing-cup-cafe-leche_2013091400021.html

 

Thanks for your examples! Marking this as solved.
