Call for Price if Price is set to Zero

[Ajeh]

What version of Zen Cart are you using?

I am looking in v1.3.0.2 ... and have products_price set to nothing ...

And mark the Product is Call for Price: YES

And I see no price displayed just the Call for Price tag ...

NOTE: I also edited the Product which puts the 0.00 into the products_price field and it is still displaying properly ...

Do you have an URL where this is not working right?

I am using v1.3.02

Yes everything works just as you explained and i understand that that is the way it is designed to display.

If price is nothing - No Display

If price is 0.00 - No Display

If price is .01 or higher - Display Price

I want to change the way it works now.

What i am looking for is the following:

1. if price is nothing - No Display

2. if price is set to 0.00 - diplay "Call for Price" image (wihtout having to check the "Product is Call For Price")

3. if price is 0.01 of more the display the price.

By doing it this way then i do not have to go into each one of the 3600 plus products (eventually over 15,000) and change the "Product is Call for Price" each and every time I have to change the price to zero. It would be an absolute nightmare to change all of these "Product is Call For Price" if it can not be done automatically on the price block.

It takes us long enough now when we have a price change to update a text file for uploading. Imagine how long it would take to update each individual item for "Price is Call For Price" after updateing the pirces.

Any ideas on how to make this happen would be greatly appriciated.

Thnaks in advance.

There is a fine distinction between nothing and 0.00

If a products_price is nothing ... and you edit ... it will become 0.00

There are other circumstances when this can happen as well ...

You can try to alter the display via the fuction but I do not think at that point you will be able to tell the difference between nothing and 0.00

Do you have any other identifier to distinguish between nothing and 0.00 on products_price?

Is this something where before adding the products to the database you could set anything that has products_price blank to a negative number that could be captured in the function to send back a blank?

Could the qualifier be blank or 0.00 price and not price_is_call = 1 to determin this should be a blank price?

I supose that when we do our pricing adjustments (every couple of days) that we could use a negative number (-0.10) to indicate that we need the "Call for Price" image to show up.

That would then mean that Zen Cart would need to show ONLY positive Prices, whick it dones not do now.

If statements could be writen to cause these adjustments to happen.

i.e.

If "prduct_price" = -0.10 then

price_is_call = 1
product_price_display = 0

else

price_is_call = 0
product_price_display = 1

Obvioulsy the correct or best variable would need to be used. But where to even start thinking about purtting these staments is where i am having a problem. I do not know enough about the linking structure yet within the pages to get started.

Any suggestions on where to start attempting such a mod would be helpfull.

One place would address all the display prices ...

Peek in the /includes/functions/functions_prices.php

The function zen_get_products_display_price manages the display ...

At the bottom, is where the Call for Price is handled ...

    // If Call for Price, Show it
    if ($product_check->fields['product_is_call']) {
      if (PRODUCTS_PRICE_IS_CALL_IMAGE_ON=='0') {
        $call_tag = '<br />' . PRODUCTS_PRICE_IS_CALL_FOR_PRICE_TEXT;
      } else {
        $call_tag = '<br />' . zen_image(DIR_WS_TEMPLATE_IMAGES . OTHER_IMAGE_CALL_FOR_PRICE, PRODUCTS_PRICE_IS_CALL_FOR_PRICE_TEXT);
      }
    } 

The final display price is whatever the results are when you hit:

    return $final_display_price . $free_tag . $call_tag; 

You can alter this return based on any condition you want either at the end of the function or build an IF to catch it right near the start after the information has been gathered in:

    $product_check = $db->Execute("select products_tax_class_id, products_price, products_priced_by_attribute, product_is_free, product_is_call from " . TABLE_PRODUCTS . " where products_id = '" . $products_id . "'" . " limit 1"); 

Note: the add to cart buttons work in a similar manner ...

The function zen_get_buy_now_button

Decides if the button has to be changed ... it follows along the same logic as the price display so to speak ...

Just catch the data with an IF before the return happens to test for your new condition ...

NOTE: there are no overrides on the functions so you will need to keep a copy of the original files and your changed files ...
