Show error after redirections

[el_caveman]

Hello guys,

 

I'm fairly new to presta development

 

I need to create a module that allows the user to upload some files on his order.

Everything seems to be working nicely except the errors when the user uploads an invalid file.

 

What I'm trying to do is something like this

 

$this->errors[] = "invalid file";
Tools::redirectLink(Context::getContext()->link->getPageLink("History"));

And I can understand why i'ts not showing the error, and I have an idea on how to make it work.

My idea was to create an instance of the historyController and display it instead of doing a redirection, but I'm not sure if that is the best option, and I'm looking for some opinions around here.

 

Thanks for your help,

Francisco
