Magento

Hi,

i would like to create a new product type for some special reasons.

in the
code/core/Mage/Catalog/etc/config.xml
the different types are configured under:
<global>
<catalog>
<product>
<type>

now i created my own module with my own config:

<global>
<catalog>
<product>
<type>
<newone translate="label" module="my_mod">
<label>New Product Type</label>
<model>catalog/product_type_mytype</model>
<index_priority>0</index_priority>
</newone>
</type>
</product>
</catalog>
</global>

the config is read correctly and the type is shown in the admin, when creating a new product. i can select the type, but when clicking “Next”, i get the error:

Warning: include(Mage/Catalog/Model/Product/Type/Mytype.php) [function.include]: failed to open stream: No such file or directory

how can i tell magento to use my own module-directory not the “Mage”?
i want put the Mytype.php in my module-dir…

thanks!

<model>catalog/product_type_mytype</model>

here you pointing magento to “Mage” folder, becouse “catalog” module is there(in xml configs).
use your own module instead of “catalog”

but i want to use catalog, because it belongs to this module. usually i can override the modules, but how tell him to look in “mycompany/catalog” ?

no way? normal modules i override also in this way…

You may have figured this out since then, but what you’re missing is a rewrite rule to say where your implementation class is:

in your_module/etc/config.xml:

And then create in your module local code pool the following class:

I try to follow your suggestion to make a costom product type but the rewrite rule don’t’ work.

This is the error

Warning: include(Mage\Rentable\Model\Product\Type.php) [function.include]: failed to open stream: No such file or directory in C:\xampp\htdocs\magento\app\code\core\Mage\Core\functions.php on line 70

I put the module in the community folder.

Wath’is wrong??

Thanks

This to don’t work

Ok!! I’ve resolved!!

Any clue how you did this?

Add another product type is very usefull.

@Davide Fiorello :
You say “I put the module in the community folder”, where is it ??

We’ve been working on a module to add an additional product type as well and we’re running into the same issue:

Warning: include(Mage\Rentable\Model\Product\Type.php)

You need to have the XML setup like:

Entering the above gets you a menu selection in the drop down menu when you add a product; which obviously is key, but when you try to use that menu item, it will try to load:

All this is fine except the Mage/ part.

So how do configure the XML so that you get both a menu item AND a correct path to your file all while keeping your files outside the mage name space?

Hi,

I’ve followed all your great help for creating a new product type, but I’m having quite a serious issue.

I’m basically trying to create a new product type based on grouped products so I’m using the grouped product model and overiding it. I can get the new product type to display in the backend, however when it comes to saving the product I get the following error

Data retreiver for ‘multi’ is not defined

Anyone else experienced this, I’m guessing I’ll have to create/override some additional files to get this working but I have no idea where to begin on this.

Any help much appreciated.
