Sharing variables across blocks
Permalink
I'm not sure if this is possible. I have one block on a page (call it A), in which I hit an API and set a variable value. I have another block(B) on the same page that depends on this variable. Is there a way for B to get access to the variable set in A?
Block A is a zip code lookup, while block B is a listing of the steps during registration. If the zip code isn't found, I set a variable indicating this in Block A (I'm using $this->set("zip_found", true) in the A controller). Block B needs to know if that variable was set (to know whether to advance the step indication).
The other option is for me to hit the API twice, which I don't want to do.
Any ideas?

Thanks for responding Sir Fish. I think I may set the registration step as a session variable, and read it from Block B. Although, there is the problem of loading...if Block B for some reason loads before Block A, the step variable won't be accurate (I haven't tried, but it seems that way).
I use:
echo print_r($global);
echo print_r($global);
If just working variables in php, you can:
- set is as a php global
- create a library or model class with the info as static data
- set it in a user's session (will now be persistent for the user)
If the block data record, you can use c5 to retrieve the block object with its data and interrogate that.
