Add a new product type in 1.5, or not...

[jeffiec]

I have a need to add products that have many fields, attributes are not the answer because the customer will not be able to choose, just a ton of new fields.
I have searched and searched for a way to add a new product type, however everything I have found in posts are pre 1.5. and not working as intended.

So my question is what is the best way to add a new product type in 1.5, is it worth it, is there a better alternative.
Thanks in advance
Jeff

The product-type concepts are the same in v1.5

What EXACTLY do you mean by "not working as intended"? That's a rather vague explanation of your problem ;)

[jeffiec]

Sorry, I meant to tell you lol,
here goes, I used the product_music as the template and copied every file i could find and renamed product_forklift following this post.

./admin/product_music.php
./admin/includes/languages/english/product_music.php

./includes/templates/template_default/templates/tpl_product_music_info_display.php
./includes/templates/custom_template/templates/tpl_product_music_info_display.php

frontend loads ok, however backend gives me a blank page.

I have traced it to forklift_type_database_names.php, which I edited after the initial 500 error crashes to this:
define('TABLE_FORKLIFT', DB_PREFIX . 'forklift')

if i rename the file, the backend comes up ok.
I am in the process of revamping the collect_info.php the match field names for the new product, not sure if this may solve the blank page issue, 49 fields is a lot lol.

even though the a post talks a lot about it, i'm still a little confused on how it will work, i found an old article that explained product types in detail, while it was written for an older version, it wasn't too helpful, i think you posted it with the article above.

My vision is to have a product named forklift, with many many (49) fields, i need to be able to save ALL of the fields at one time and associated with a particular forklift.

Is your define() statement missing a closing semicolon?
What's the actual PHP error message?

backend gives me a blank page.

[jeffiec]

if (!defined('IS_ADMIN_FLAG')) {
die('Illegal Access');
}
define('TABLE_FORKLIFT', DB_PREFIX . 'forklift');

no errors, just the white page, renaming the file seems to at least get the page back.

And wouldn't you know, I cleaned the white spaces after the end php tag and it comes up lol. Prolly shoulda done that before I posted.

I will let you know how the rest goes, I have the tedious job of going through all the files in the product_forklift folder to make the logic work.

Your aide is invaluable, no amount of money could ever repay the knowledge that you share with us, I am glad to be of acquaintance

PS. You were kind of giving me direction on another post http://www.zen-cart.com/showthread.p...36#post1186536, where should i put the business logic? is there a tutorial or post i can reference?

Lol ... I know how that goes.
In fact, why not just remove the ending PHP tag. Explained here: http://www.zen-cart.com/content.php?...nd-of-the-file

After clicking Preview, then Insert, I get this error,
WARNING: An Error occurred, please refresh the page and try again.
Thinking either I cant use the product_id in this:
'forklift_id' => (int)$products_id,
or this tag is malformed by the [$language_id] tag:
'forklift_make' => zen_db_prepare_input($_POST['forklift_make'][$language_id]),

Just not too sure what ties the extra data to a particular product.

You'll need to find the exact error. See: http://www.zen-cart.com/content.php?...-and-try-again

[jeffiec]

Bah!!!
After several misspelling errors, both in the arrays and in the table, it is working!
I knew the logs were somewhere, i just couldnt find them lol.

Just to clarify though, the preview file is going to have to be adjusted too huh?

Thanks again

[DrByte]

A definite maybe, depending on what all you've added to your custom product type.
