Passing and using post variables in WB

[whitsey]

Hi,

Hoping someone can help with this query.

1. I am passing some variables via the query string (?key1=value1&key2=value2) and want to know how I can use these within the WYSIWYG editor.  I just want to display a success message with the values that are passed.  How do I access these values from within WYSIWYG editor?

2. Is there a site constant variable that will easily identify to me what the parent page of the current page is? (see below)

Page 1
----- Page 1.1
----- Page 1.2
----- Page 1.3
Page 2
----- Page 2.1
----- Page 2.2
----- Page 2.3

From Page 1.1 how can I access the URL of Page 1 dynamically? (I want to pass it via a form value so that the resulting page has the "category page" that I just linked from to link back to) 
NOTE: I know I can achieve this manually but I have about 20+ pages to update which is a pain - I would like to figure out how to do it dynamically

Hi,

for 1.)
you cannot use PHP Code in the WYSIWYG Editor. So you can not handle the variable you get per post.
But you can use a section type "code" above your WYSIWYG section and put the necessary code for handling you data in it and display it there.

for 2.)
please have a look at Variables and Constants on the help-pages. There you find, beside many others a constant called "PARENT" ...

Thanks for that, much appreciated.

Now I can access these variables that is great however, how do I convert this into an on page link.

Page 1
----- Page 1.1
----- Page 1.2
----- Page 1.3
Page 2
----- Page 2.1
----- Page 2.2
----- Page 2.3
Page 3

i.e.
a) From Page 1.1 I can now retrieve PARENT.
b) I pass this to Page 3 as a variable and can access it from the query string
c) Now I want to use this ID to create a link on Page 3 to link back to the parent page(the category I just came from) i.e. Page 1

From Page

Hi,
sorry if may sound a little stupid at this point - english isn't my natural language.
You could handle a.) and b.) did I understand that correct?
Your trouble now is on c.) ?

Regards Bernd

[whitsey]

Yes, apologies.  Your response answered questions a) & b) however it returned an ID instead of the page_url.  Now I need to convert the ID into a page_url to display as a link.

Thanks

[BerndJM]

ok,
convert the ID (it's the parents ID - right?) into an URL for a backlink.
You need a additional database query at this moment, who looks for the ID (either the 'page_id' or the 'parent' or the 'root_parent' - depending on the case you want to realize) and reads there the 'link' - which points to the correct filename in the /pages directory.

Thanks Bernd,

Does this mean I need to srcipt a db call or is there a function that exists to do this for me?

[BerndJM]

Yes this means you have to script a appropriate db-query that fetches the required information.
At this point. the only available information you have is the id so you have to get the information you need from the database.
