Hi,

I’m trying to use the Price by Quantity Threshold Fieldtype http://cartthrob.com/docs/fieldtypes/price_quantity_threshold/index.html
Once I add the fieldtype to my channel and try to add/edit a product, I get a bunch of errors.

A PHP Error was encountered
Severity: Notice
Message: Undefined index: entry_id
Filename: fieldtypes/ft.cartthrob_matrix.php
Line Number: 700

A PHP Error was encountered
Severity: Warning
Message: Cannot modify header information - headers already sent by (output started at .../system/codeigniter/system/core/Exceptions.php:170)

Severity: Warning

Filename: libraries/Functions.php
Line Number: 393

When I come back to the edit screen, the correct values are there. If I hit submit again, I still get the errors.

Also, when I use the tag in my template, I get the following errors.

Thanks

In the default install of the templates, main cart page displays following php error:

A PHP Error was encountered
Severity: Notice
Message: Undefined property: Cartthrob_package_ft::$prefix_only
Filename: fieldtypes/ft.cartthrob_matrix.php
Line Number: 615

It happens when displaying packages with following code:

Make sure line 40 of ft.cartthrob_matrix.php in cartthrob > field types looks like this:

at sometime it was prefixed_only or something ilke that. I know we corrected it, but I’m not sure if it’s made it out into the general release. Start with that fix. Log out and back in and try again. It might not fix everything, but lets start there.

This didn’t seem to fix it.
Also, it now happens when I submit on any channel. Even ones that have nothing to do with Cartthrob.

Same exact errors?

Yes it is.

Removing the custom field from the CT Product custom field group gets rid of the errors.

I still can’t use the field, though.
However, it’s not a priority right now. I’ll be talking to Chris tomorrow about custom work anyway. I won’t end up using this fieldtype.

I made a fix, which should correct this error. Even though the issue’s now moot for you, I thought I’d post it in here for posterity’s sake.

What’s the fix?

Hah. It’s been 3 weeks. I don’t recall. Whatever it was, I put it into the core. Rob was supposed to roll up a new version on Monday, but I don’t think he did yet. It’ll be included in 2.1.4+
