Display Price for Login Members Only

[clustersolutions]

Wrote this module for a new store and tried no core code change but no deal...I have couple questions and any answers are welcome.

 

https://github.com/clustersolutions/osc-price-display-members-only

 

1. 1 line added to admin/modules.php and I had to use the class file in the catalog side and not the admin because the currencies class aren't the same between the two sides. Perhaps these classes should be consolidated.
2. I wanted the module to be self contained, so I extended the currencies class inside the module, but the procedural step in oscTemplate had called out TEMPLATE_BLOCK_GROUPS = 'boxes;header_tags' in this order and I had to flip the TEMPLATE_BLOCK_GROUPS order around so the boxes would also pickup the change in this module.
3. "update configuration set configuration_value = 'header_tags;boxes' where configuration_key = 'TEMPLATE_BLOCK_GROUPS';" This is what I used, now, is TEMPLATE_BLOCK_GROUPS controlled only from a mysql shell?
4. The alternative would be to add the currencies_mod class file into the class folder and modify the currencies class line in applicaton_top.php. Well, remember my goal was minimum core code change? This method is also kinda messy should the module be uninstalled...
5. May be extending oscTemplates with an updateBlocks() method?
6. Perhaps a class loader would be nice...may be that's already in 2.4 but I had not browsed through the 2.4 codes...but the class loader would have to be very robust and be able to deal with different modules perhaps extending the same class and tinkering with the same method...hmmm?!

Any thoughts???

Coupla things

- how do you create currency as the extended class without a core mod?

- why do you want to refer to the currency on the admin side for the module? Aren't you just installing & uninstalling?

- I guess by not working unless resequencing you're saying that the currency extension didn't get picked up soon enough. If you want to swap that variable round you could do it in your install function (and put it back in the remove), but I'd manipulate rather than overwrite it. Have you checked if there are unintended consequences to other processing?

 

Assuming this isn't the only thing you're trying to change in your store, maybe it's worth putting a single core change into application top to load extra classes. There'd be no core changes specifically for this mod, and you could use the same hook for other mods.

 

Probably easier to maintain than fiddling with execution order that might have unintended consequences either now or - worse - at some point down the line when you've forgotten about what this mod involved!

[clustersolutions]

- currencies_mod was extended in the module file, and $currencies was re-initialized in execute().

 

https://github.com/clustersolutions/osc-price-display-members-only/blob/master/catalog/includes/modules/header_tags/ht_price_display.php

 

- I developed this on edge and is using it on another dev bs platform that's hacked. Yes, install and uninstall from the admin side...

 

- If you look at application_top.php it is still very procedural...I don't see any reason why the block boxes has to executed b4 the header_tags; however I will fix whatever unintentional consequences that may arise. But so far so good.

 

- Another way would be to add a "preloader" thing to TEMPLATE_BLOCK_GROUPS; i.e. "preloader;boxes;header_tags"; but I think I may already be abusing the header_tags block and getting more mileages out of it than I should...

 

- All my sites are on git now...and should this "resequencing" caused any problem I should be able to pinpoint that in the future.

 

- Extending oscTemplates with a updateBlocks() seems like the best deal...but soon enough I may find myself extending to an extension...well u know what I mean...

 

- A more robust way to manage classes without touching the core would be ideal...to me core code change is like all or nothing...

 

- Hey, this happens to any software, just last week a client was telling me they stick with Magento extension from the same company because they guarantee no conflicts :)

You could built a preloader block in alhabetic order. For example asomethigpreloader or bootstrap_blocks group names which overtake  boxes and header tags in sort order loading.

 

"preloader" name is a bad way.

[clustersolutions]

@@Gergely, thx, and I agree with you that is probably an easiest fix for now and it allows me to add my extended class. U know, I am so bad at naming variables I think it is harder than naming ur own child...preloader is probably a magic quote? I'll come up with something else...thx, again! Tim

I have combined your idea with this addon and its perfect! I used as bootstrap modules not 960gs.

and so on

new products and all boxes working well.

'<div class="remove"></div>';

@@Gergely, that was just for removing the button around the price when it is hidden. Perhaps it won't be necessary if u don't wrap the price in a button under category/product page? It was a quick fit...I don't use it as I don't wrap my price inside a button...would it cause any problem?

@@clustersolutions generally not cause any problem but would be nicely display nothing.   or a simple space.

@@Gergely, true, will look into another way to remove the btn that wraps the price...

Здравствуйте Сергей.

Я установил на сервер все файлы. Но редактировать не понимаю как . У меня различаются файлы PHP с Вашими.

У меня нет того что надо заменить. Установлена вот эта версия.oscommerce_2.3.4_bootstrap_rus. Помогите,

2. includes/template_top.php

 

Change:

To:

<div id="bodyWrapper<?php echo $oscTemplate->getBlocks('960grid_css_developer'); ?>" class="container_<?php echo $oscTemplate->getGridContainerWidth(); ?>">

 

 

Change: 

 

if (!$oscTemplate->hasBlocks('boxes_column_left')) {

    $oscTemplate->setGridContentWidth($oscTemplate->getGridContentWidth() + $oscTemplate->getGridColumnWidth());

  }

  if (!$oscTemplate->hasBlocks('boxes_column_right')) {

   $oscTemplate->setGridContentWidth($oscTemplate->getGridContentWidth() + $oscTemplate->getGridColumnWidth());

Hey @clustersolutions this addon is great and is really what I need for my B2B website...

I am wondering if you could give me a few pointers on how to modify it a bit to work for my store - which is strictly Wholesale only . I don't want non authorised members being able to see prices or generate orders .

I am using SPPC on my site and would really like to modify 'display price for login members only' so that it checks if the customer is part of the default SPPC group (customers_group_id = 0) so that if they are part of group 0 they are treated as not being logged in. It is only once their status to another SPPC group has been updated in admin that they can see prices.   

The 'customers_group_id' field is in the customers table so it should not be to hard to do, but I just can't get my head around it - have you got any thoughts on where I should start?

[clustersolutions]

Your requirements still kinda vague, it can be done, but you will need to get familiar with both modules/apps in order to integrate it. May be try to ask some more specific questions? I will have to wait until I have the time to refresh my memory on even my own codes...thx!

[Portman]

Ok... here goes,

SPPC allows you to create a number of customer groups to allow different prices for different customer groups. The default group is 0, then you have groups 1,2,3 etc which are applied on the admin side  of the site.

as part of the mod an extra field is added to the ‘customers’ table called ‘customers_group_id’ when a new customer creates an account that is set to 0. 

What I was hoping to do was to modify your app so that it does not show prices if the customer is not logged in, but it also does not show prices if the customers_group_id is 0 (essentially meaning that they don’t see prices and cannot purchase from my site until I have approved them by setting  customer_group_id to something other than 0)

[clustersolutions]

@Portman  This is where you can make it happen...it was a simple module.

https://github.com/clustersolutions/osc-price-display-members-only/blob/9f3970e9e8dbf8deabe2100dbb5ff69a5db5e9c4/catalog/includes/modules/bootstrap/bt_price_display.php#L67

You will need to make sure that the $customers_group_id was already registered as a session variable  before this module. Modify the if conditional statement to validate $customers_group_id per your requirements..

if (tep_session_is_registered('customer_id') && tep_session_is_registered('customers_group_id') && $customers_group_id > 0 && defined(MODULE_BOOTSTRAP_PRICE_DISPLAY_STATUS) && MODULE_BOOTSTRAP_PRICE_DISPLAY_STATUS == 'True') {
.
.
.

I hope this make sense...but you need to test it to be sure.
