passing session variable in v10

[richard2007]

not sure if i am doing this wrong or a v10 bug.

i have a button on a detail view popup window. the button opens an .a5w page and also puts a field value in to a session variable.

the .a5w page opens and allows the user to upload an image, working fine so far. part of the code to upload the image also updates the value in a field in the table being worked on.

however when the code to upload the image is run, the image loads fine but i receive an error with regards to the session variable.

code

<%A5
dim msg as c = ""

if eval_valid("cmd")

    file.from_blob("[PathAlias.ADB_Path]\photos\\" + FileToUpload.filename, FileToUpload.data)

	dta="Image =" + "[PathAlias.ADB_path]\photos\\" + FileToUpload.filename
	record_update("[PathAlias.ADB_Path]\titems.dbf","itemid="+quote(session.__protected__itemid),dta)
	
    msg = "<a href=\"/" + FileToUpload.filename + "\" target=\"_blank\">" + FileToUpload.filename + "</a> was uploaded<br /><br />"
end if
	
%>

error

"Script Error
Error:Script: /h_secure/upload.a5w line:12
record_update("[PathAlias.ADB_Path]\titems.dbf","itemid="+quote(session.__prote
Property not found
session.__protected__itemid subelement not found."

Re: passing session variavle in v10

i think i have worked this one out.

Re: passing session variavle in v10

nope i havent worked this out.

i have

1. a button on a detail view pop up window in v10
2. the button opens a new a5w page in a pop up window and assigns a session variable based upon the value of the id field for that record

upload.a5w?v_itemid={itemid}

3. declared the variable on the page 'upload.a5w'

the variable doesnt appear to be set by the button - if i set the value on the 'upload.a5w' page as a static value then the 'upload.a5w' page works fine, but not if i am relying on the variable to come from the button on the detail view.

i hope this makes sense.

Re: passing session variavle in v10

I can't tell from your example, does your URL contain the session var, such as "mypage.a5w?v_itemid=session.__protected__itemid"?

If so, can't. You can never use a protected session variable in a URL. The way your example shows, v_itemid would be a page variable on the A5W page and contain whatever value you have in your {itemid} from the grid.

Re: passing session variavle in v10

hi steve,

no protected in the session variable. i am just using the java scripts attached to the button to open a page and assign a variable.

i need to pass the value of the itemid field for the current record.

The way your example shows, v_itemid would be a page variable on the A5W page and contain whatever value you have in your {itemid} from the grid.

this is exactly what i need to be passed from the items.a5w page which has the grid 'view_bedroom' to the page upload.a5w

the button, opens upload.a5w page to allow the user to upload an image and then code on the upload.a5w page updates a record filtered based upon the session variable i am trying to pass.

if anyone has the time, my app is attached.

the page items.a5w starts the process, when the 'upload image' button in a records detail view is pressed

the page upload.a5w has the code to update the values in the record for which i need the session variable

you will need the v10 beta and i am working with yesterdays release.

Re: passing session variavle in v10

I guess I can't see where any session variable needs to be involved. You are bringing over the item id as a page variable named v_itemid. So what's the session variable used for other than to filter your grid? How the grid was filtered does not matter once you leave the grid to go to another page. Your record_update code would be:

record_update("[PathAlias.ADB_Path]\titems.dbf","itemid="+quote(v_itemid),dta)

(maybe without the quote(), I can't remember right now.)

Re: passing session variavle in v10

i believe the session variable needs to be available to the page upload.a5w so it knows which record to update.

maybe i am confused on session and page variables, either way i need the value of the item id of the selected record to be available to the upload.a5w page.

i thought the value would be available by assigning the value to a variable when the button is clicked.

How the grid was filtered does not matter once you leave the grid to go to another page

i understand this but am more concerned with having the value available to update a particular record.

record_update("[PathAlias.ADB_Path]\titems.dbf","itemid="+quote(v_itemid),dta)

i tried this and it wouldnt work - something i am doing maybe, but i copied word for word.

if i set a static value for variable v_itemid in the upload.a5w, the whole thing works fine, so my problem is in getting the value of itemid from the grid/details view to the upload.a5w page. am i completely missing something?

Re: passing session variable in v10

Hi Richard,

i also experience the same thing, i think this is a bug for v10 (cannot passing the session variable), while i tried the same component and page in v9 and the session variable worked fine.

Re: passing session variable in v10

Richard, when you click the link in the grid, what is in the URL? And what is the code you used on the grid to create that link?

If the value is passed in a link, it a Page Variable. If the variable takes the form session.myvar, then it is a Session Variable. Session variables are not 'passed' between pages. They are set at any point by your application using xbasic almost always defined in an A5W page. They persist until destroyed by more xbasic code, or the session times out.

Re: passing session variable in v10

Hi Steve,

Yes you are right, it's a Page Variable because the value is passed in a link, i tested to pass the page variable in a header grid link and the target page will be child grid, on the child grid event then i use the page variable (that i pass from the header grid link) and i got error message "property (Page variable) is not found". you can see that attachment for more clear.

FYI: it's only happen for V10 and in V9 it works fine.

Regards,
Andy

Re: passing session variable in v10

I looked at your attachment. I would never establish a URL that populates a session variable. Both because there is no need, and because you encourage visitors to play with the value to see what they can hack.

But that is besides the point. I guess if it worked in V9 and does not in V10, I haven't a clue. If I were you I would test to see if you can include a session variable in a URL in version 10. Run a simple test like this in V9 and V10:

mypage.a5w?session.name=Steve

and on mypage.a5w include this, see if you get an error, or "Steve" or nothing.

?"Name is: " + session.name

Not saying its true, but if I were developing V10, I would eliminate the ability to set session variables in a URL.

Re: passing session variable in v10

hi, been away for a few days

Richard, when you click the link in the grid, what is in the URL? And what is the code you used on the grid to create that link?

because the link opens an ajax window, i cant see the value being passed to the URL.

i wasnt sure what variable was being set, page or session as i was just setting the variable in the action scripts for the button which opens the ajax window.

ill update with the latest builds and see if it makes any difference.

Re: passing session variable in v10

Hi Richard,

i just create another title for this page variable, and i also attach component, pages and DBF that are ready to test and also VIDEO in MP4 format, you can test it and please let me know the result. please see title 'v10 : page variable that passed to target page is not recognized in the target pages.'

regards,
Andy

Re: passing session variable in v10

See my response at http://msgboard.alphasoftware.com/al...ad.php?t=80807.

I think I proved that you cannot set a session variables value in a URL in V10. Which I happen to think is a good thing.

because the link opens an ajax window, i cant see the value being passed to the URL.

Yes you can, even if the address bar is hidden, you can include this on your target page:

save_to_file(Request.Request_URI,"c:\test.txt") which would dump out something like: /index.html?foo=bar&this=that

what i meant was i coudnt physically see this myself, therefore can not see if the value is being added to the url

is there a way to check this?
