Error, warning and success messages

[rasmusb]

I am creating a module and need to show error, warning and success messages on the configuration page.

 

I have seen code like this in other modules:

$this->warnings[] = $this->l('Warning...');
$this->context->smarty->assign('form_infos', $this->warnings);

... but i can't seem to make it work.

 

Is there a way to add messages to an array as text strings and have them rendered using the default error, warning and success prestashop templates?

Maybe have a look in a file like 

 

   /modules/blocklink/blocklink.php

in function:

  public function getContent()

 

 

Where they use calls to functions (defined in classes/module/Module.php)

 

  $this->_html .= $this->displayError($this->l('Bad URL'));

and 

  $this->_html .= $this->displayConfirmation($this->l('The link has been added.'));

 

 

Have a look.

 

 

My 2 cents,

pascal.

Thanks Pascal, that's very helpful.

 

I managed to find the last bit I was looking for on my own. By adding...

$this->warning = $this->l('Bad configuration.');

...to the __contruct method a warning is shown whenever the modules admin page is opened.
