Retrieving/Passing a Set Preference Value

[ctflatt]

After successfully implementing Klaus' excellent Preferences tutorial on the iPad (Part 1: http://runrev.com/newsletter/october/is ... etter3.php and Part 2: http://runrev.com/newsletter/december/i ... etter4.php), I am trying to retrieve a set "email" preference value from a substack and use it in the main stack.

Not sure how I would achieve the following:

From the main stack I need to pass a value from a sub stack in a URL.

I have successfully hardcoded the email into the script, but need to make the email value equal the set "email" preference...

Here's the script I have:

Code: Select all

iphoneControlSet sBrowserId, "url", "http://www.someserver.com/directory/index.php?email=someone@somewhere.com"

How do I get the value of the "email" preference (which is already set in a substack field) passed in this main stack script?

Does this make sense?

Thanks!

Hi cflatt,

thanks for the flowers

Do this:
...
put ("http://www.someserver.com/directory/ind ... il=someone@" & fld "whatever holds the mail address") into tUrl
iphoneControlSet sBrowserId, "url", tUrl
...
Or do I misunderstand this?

Klaus:

You're welcome! It was great...

The fld "that holds the value" is set in a substack... how do I reference a value from a sub stack in the main one?

From the main stack:

get the value of fld "email" of card 1 of substack "preferences"
put it into tEmail
put ("http://www.someserver.com/directory/index.php?email=" & tEmail") into tUrl
iphoneControlSet sBrowserId, "url", tUrl

Does this look even remotely right?

Hi Todd,

almost correct! Remember that the obvious is often the corrcet way in LiveCode
...
put the text of fld "email" of card 1 of stack "preferences" into tEmail
put ("http://www.someserver.com/directory/index.php?email=" & tEmail") into tUrl
iphoneControlSet sBrowserId, "url", tUrl
...

Klaus:

Sorry... getting a script error... I think it has to do with the quotes in what we've written...

Code: Select all

Script: missing "" after literal

Did I/we close them properly?

Hi Todd,

sorry, there is one QUOTE too much after tEmail!

This is correct:
...
put the text of fld "email" of card 1 of stack "preferences" into tEmail
put ("http://www.someserver.com/directory/index.php?email=" & tEmail) into tUrl
iphoneControlSet sBrowserId, "url", tUrl
...
