[Solved] Override class still existing

[MacroProg]

Hello.

 

I need to override the PDF class to add it a new static function.

 

My problem is the next : there is yet an override of the PDF class done.

 

How can I do to add mine ?

 

Can I name PDF2.php my file ? DO I have to add it to the existing file ?

 

Thanks for your answers.

if PDF.php already exists in the override/classes folder, then you would just edit that existing one, and include your new function.

[MacroProg]

That's what I think about, but this isn't a very good solution because, if the other module that firstly installed the override of PDF is uninstall, it will broke my module.

 

Well, I will think about it, and if I found another way or a solution for this problem, I will post it.

 

Otherwise, if anyone has another solution, thanks to telling me.

it is the only solution if you want to override the PDF class. otherwise add your code somewhere else. why do you want to add a new static function to the PDF class? what would execute the function?

[MacroProg]

it's because I need to print a specific document whith Prestashop data from the front-end and the back-end. So, I thought that the override was the best way, isn't it ?

[bellini13]

yes, creating an override is the appropriate action, however you do not want to because an override already exists. your options then are

1) edit the existing override and add your functionality

2) create your own custom PDF class (ie. PDF2.php) that perhaps extends PDF.php

[MacroProg]

Well, I start with your first solution but I didn't thougth about your 2nd. It's interesting. Ok, thanks, for your help, I will see which one is better for me (probably the 2nd because this avoid the problem of uninstall).

 

Thanks

one other thing to review. the module that overrides PDF.php, have you reviewed the module uninstall code to see if it actually deletes the override file?

[MacroProg]

yes, it overrides it, unfortunately.

[bellini13]

but when the module is uninstalled, does it delete the override file? please provide the modules uninstall function here

[MacroProg]

yes, it's shure it delete the override file.

 

but I writting my custom class that extends the first one.

 

Thanks for your help. How can I check this conversation as solved ? I can't find a button for that.

I think you edit the first topic using full editor, and just change the subject

[MacroProg]

Thanks again, it's done
