Issue Linking App Flow to a Page

Wappler General Need Help
1

Hi there @teodor…

I’ve started a new project in v6 beta 16 and I’m testing out linking an app flow to a page.

I’ve created a simple page index.php with a data store, and linked that page to the app flow, but when I try to add a run command in the app flow, the data store and other page elements aren’t showing… can you tell me what I have done wrong please?

Thanks!

Antony.

Hey @Antony,

I’m confused…

I think you’re talking about “App Flow” but you describe a “Page Flow”…
If you’re talking about AppFlow the source attribute is missing in your dmx-flowdeclaration src="app/flows/app_flow.json"

Page Flows create a .json file?

App Flows do not have context of what’s on a page. Think of them like Server Connects. You can define params in them and then after adding an App Flow to a page you can pass values into the params for use in the App Flow.

(@teodor, I'd appreciate your views on this...)

So within an App Flow, I cannot access elements of an associated page like a Data Store?

I hoped this could be allowed by the linked page... if not, then what is the linked page for? :thinking:

So to be clear, I want to be able to execute a Run command in the app flow that manipulates the DataStore in the page index.php... but when I try to populate the Run command in the App Flow there are no Actions to select:

app_flow_run_empty

(I have now added reference to the Page Flow to index.php)

<script is="dmx-flow" id="app_flow" type="text/dmx-flow" src="/app/flows/app_flow.json"></script>

That is not possible, as this is not how App Flows work and @kfawcett already explained you how the things work.

Thanks @teodor…

Can you tell me what the Linked Page feature does please?

It does nothing for App Flows, it’s used on Server Connect to import form inputs under Input > $_POST

Thanks @Teodor…

I’m wondering why there is an outstanding bug report from @mebeingken which is asking the same question as I am?

If you just need to have the datastore available in your AppFlow, just pass the datastore as an argument to the AppFlow when you call it on index.php, for example:
app_flow.run( dstore: datastore_id)

Then you can find it under $params in your AppFlow
$params->dstore

First create under $params the desired variable(object) call it the way you want (eg “dstore”) and then when you call it on your index you pick the datastore there)

No, it’s not possible. Please read George’s explanation again.
