Can someone fix this one syntax error? syntax error, unexpected 'public' (T_PUBLIC) ps_categorytree.php

Billy · September 10, 2021

I have this example code below from the ( Main Menu in Prestashop 1.7.7.7 )

Which is called the ( ps_categorytree module )

In this example I have modified the bottom of the file with the code from

https://www.sunnytoo.com/8222/how-to-set-the-category-tree-links-module-to-expand-the-brunch-containing-current-category-in-prestashop-1-7

I am getting a ( syntax error, unexpected 'public' (T_PUBLIC) on line ( 338, 1 )

Can anyone fix this one issue please please please. Could you fix it down at the bottom and repost the whole file? I have been going around and around with this menu.

Thank you in Advance! Billy

Well then I would be back to a module that doesn't work. You see the ps_categorytree module in presta 1.7.7.7 does not work. It has no visual where your at in the menu. It doesn't expand on the category your in or even highlight where your at. As it does not open up.

All I could find to solve the issue with the menu which come with prestahop 1.7.7.7 was that tutorial. I don't understand how a perfectly good working menu in prestashop 1.6 loses all it features. The module is wrecked and I need help to solve this issue.

If anyone could just fix the darn ps_categorytree.php to work again like in presta 1.6 that would be great...

Some of the 1.6. x.x modules won't work in 1.7 versions. The 1.6. versions are quite stable why did you seek an update?

Hey Nickz my old website is Presta 1.6.1.10 in which php expire. So this old website no good anymore

So I have built new website to replace the old one out of Presta 1.7.7.7 however the main menu in Presta 1.7.7.7 which is called ps_categorytree in the 1.7 module folder has been stripped out of it's features. It does not work like the Presta 1.6 versions.

The Presta 1.7 ps_categorytree module does not work as intended. It's been robbed of important code. (example)

1) The menu just stays closed when you click on category. (Example you open menu to a category. Then click on a category. So now the website will go to that page and the menu is no longer open. It's closed again instead of being open and you have no idea where your at on the website. The module does not work. No matter what the settings inside of module are.

So only solution is to fix the presta 1.7 module. I hope you understand now.

The presta 1.7 menu module is broken... I'm trying to fix the darn thing on my new presta 1.7 website.

Thanks man

You can rent a VPS for little money and maintain php in the parameters required for some years to come. From 1.6.1.24 you can have all what worked in that set up. The advantage is that you don't have to follow the update circuits shared servers request from their customers.

I appreciate your replays man I really do. However all I need to do is fix one syntax error in that little bit of code or better yet maybe somebody can grab that file out of a new download of prestashop 1.7.7.7

Then upgrade that one file so the menu works in 1.7 I'm not sure why a dev hasn't fixed the menu in 1.7 it's just crazy.

1.6 is done and over with prestashop. If I wanted to run presta 1.6 I would upgrade the website to Thirty Bees in all due respect.

So please if you can fix the file in 1.7 that would be great...

Thanks

Oh I have VPS with this one website on it. I can do what ever I want with VPS as I have root. I'm moving on with newer PHP and Presta 1.7

You should set up the VPS to run php7.1 and go the update to 1.6..1.24. Than concentrate on making that shop of yours work, i.e. make money.

The update game for a shop coming from 1.6.1.10 is endless once your run above php7.3. Your modules are not updated and to update a module $10 won't do it.

Billy · September 10, 2021

Dude my 1.6.1.10 shop run's php 7.2 and has for a couple of years. I fixed every file for it to run on it.

I have built this shop since 2010 here on presta and started this shop on presta version 1.3.1

I have modified 1000 of files.

I'm stuck on this one file and that's it.

I am almost ready to transfer this new 1.7 site in place of the old 1.6.

So again thanks for all the info.

Maybe $10.00 isn't enough to fix one syntax error but I had to start somewhere. My point being that in all these posts we have went back and fourth. You probably could have fixed a spacing issue which it probably is. I'm not sure but the code is already there to do it and I even linked to the code to do this. For some reason I haven't been able to figure out where the spacing issue is. I thought it was between "context-> controller (remove all the spaces)" but that didn't work.

I'm not sure how much you want to get paid for removing a spacing issue on on file down at the bottom but I'm all ears at this point because I just don't see it.

So do tell this old man who has been building presta sites since version 1.2.9 how much you want to fix it?

Otherwise just move on. Maybe somebody else will come inhere and post this one file all cleaned up to work. So everyone can use it. Maybe somebody will answer my other post. Here

However I have at least $10.00 for the first person to post the correct code for that file from sunnytoo.com

Hey @Billy

Think you just need closing } before "public static function getTreePath" and another one at very end to match class one.

}

Not tested but should work.
