Display error message or warning in backoffice

[Shwamateur]

Hi everyone, im struggling with this problem:

 

I want to display a warning or an error message (whichever is easier to do) from a module.

More concretely i'm trying to achieve this from a module.

 

The goal is that a message like this is shown:

 

 

whenever any user updates a product and he or she doesn't select a supplier for the product.

I'm trying to trigger this from the hook  "hookupdateproduct".

 

Can anyone help me, please?

 

Thank you in advance.

Anyone? I thought this shouldn't be so difficult....

you are light on details, does your module have a form that is interacting with the shop owner?

 

if so then when they save or do some other action then display the message in the form.

I have this same question, but I'll add some more info as the OP seems to have left the thread.

 

I'm using PS1.6 and I've created a module that adds a new product tab to the back office.

This works just fine, but I want to throw an error when someone forgets to fill out a specific field.

 

Inside of my module, during actionProductSave, actionProductUpdate and actionObjectProductUpdateAfter I've added $this->displayError('Oh dear!'); and made the method return false, but that didn't help.

Neither did $this->errors[] = Tools::displayError('Oh dear');

 

Any ideas?

Ha! That did the trick.

I guess I need to learn a bit more about that context object.

 

Thanks a lot!

What did the trick? There is no previous message.

Anyway, the way to achieve what OP was asking for is 

$this->adminDisplayWarning('Your message');
