Re: [VuFind-Tech] HoldLogic.php addLink variable question

Hi Folks,

You could add an isILLRequest value to the holdings array - that way, when you get to the placeHold function, you can check for it and then use send the details to _checkMethodILLs.You shouldn't have to change any of the core code then...

Cheers,

Luke

Hello Demian,

Actually there are special occasions when we let the patron choose between ILL and a hold. We have some Aleph ADMs that have multiple libraries across larger areas. They let their patrons decide how they want to handle things. Its mostly where the patrons want to pick up the item.

I like starting with HoldLogic because it handles the logon for the patron, we really only want one link for logging on. Its after the patron logs on and I examine the item and patron that I can determine what link to put up.

To start with I was going with the Hold OR ILL link. I was going to look at the special cases afterwards. Just adding the simple case is a bit of coding. Because it is not just creating ILL requests. I also need to go into MyResearch and add displaying, canceling, and renewing ILLs. Then there is creating ILL requests from a blank form. All things that are important to us and available through the Aleph Restful API.

I'm attempting to do this with as little disruption to the current code as I can. I'm hoping to just add new classes that are only used for ILL.
I've modified HoldLogic.php and it looks like I'll have to add a function to CatalogConnection.php as it has a _checkMethodHolds function and I'll need a _checkMethodILLs fuinction.
