Re: [PHP] Modifying the sort order of a query
Thanks Jay,
Well, I went back to work on it, and with the combined suggestions from the
list, it's working now. I just had to insert the sub-select on the called
page as well. That seemed to be the problem.
Thanks for your suggestion -- I used part of it.
Regards,
Andre

I've just tried the sub-select approach. Works great on the first page -
shows names listed alphabetically sorted by country. However, once I click
on
'Next 20' both sorts go bye-bye (neither by name nor country).
[/snip]
I am late to the thread but I wanted to offer another suggestion. Retrieve
the data results into an array and sort the array. I like Peter's idea
though, using a case statement for the appropriate sort order information.
You could also set a variable ($lastSortOrder) to 'default', 'country',
'city', 'whatever' and place this variable within the query. Pseudocode
follows;
$lastSortOrder = "default"
$query = "SELECT name, address, city, state, zip FROM table ";
$query .= "ORDER BY " . $lastSortOrder . ";
switch($action){
case "Sort By Country":
$lastSortOrder = "country"
break;
case "Sort By City":
$lastSortOrder = "city"
break;
}
I know this isn't complete but I HTH!

Re: [PHP] Modifying the sort order of a query
Hi Peter, I've just tried the sub-select approach. Works great on the first page - shows names listed alphabetically sorted by country. However, once I click on 'Next 20' both sorts go bye-bye (neither by name nor country). Going to try what you suggest tomorrow. I think it'll work.

RE: [PHP] Modifying the sort order of a query
Andre Don't know how useful this will be to you .. but was following thru this and thought why wouldn't you include a page with a switch statement or the like into all the pages... so that all pages know about but not always use the queries ... so that you can have it sorted by any and everything you want... any way just a thought cheers Peter -Original Message- From: Andre Dubuc [mailto:[EMAIL PROTECTED]] Sent: Thursday, 6 June 2002 1:27 PM To: [EMAIL PROTECTED] Subject: Re: [PHP] Modifying the sort order of a query Hi John, Oh, my apologies again.

You have a list of documents, 20 per page. You want to be able to sort it by country or another column, yet still display them in alphabetical order?

Re: [PHP] Modifying the sort order of a query
Hi John, Sorry about that. I should have explained what I meant. The basic problem that I'm trying (desparately) to skirt around is a troublesome paging problem. The basic query loads all files in the db sorted by name. The first page that displays has a "Next 20" button that loads the next page, and so on until the last page which has no "Next 20" button, but deadends. The problem I've faced today, is that I originally allowed a "Sort by Country" button to appear on each page -- thereby messing up the original paging. It, of course, returned to the first page (which didn't know squat about whatever the calling page asked for). Thus, the whole thing froze -- which is to be expected. The resolution, in my mind, is simple: do not have that button anywhere but on the first page (it took me a long time to figure that one out, duhh :>). The second solution, is somewhat better: using a sub-query, which will re-paginate all right, but I still need to retain the alpahbetical order of names as well. Perhaps I can't have both. (I think I'll have to try both -- my mind's a bit blitzed from the problems I've resolved today!) So, that's what I'm trying to do. The page I'm working on is a protype for about three other similar ones. Regards, Andre On Wednesday 05 June 2002 10:22 pm, you wrote: > What do you mean it'll "trash the current paging" ??

Re: [PHP] Modifying the sort order of a query
Thanks John,
That looks promising, but the question remains -- would it affect the current
paging? I really don't wnat to spend another day getting that going again! :>
Further, the actual ID numbers that would populate 'display_ids' . . .
'would be generated from your result set' -- I'm not clear how to achieve
this. From the query results, how would I extract that info, for the current
page, if my id column is 'rid', and I'm using $_SESSION['rid']?

RE: [PHP] Modifying the sort order of a query
What do you mean it'll "trash the current paging" ?? Can you give a more detailed explanation? Results 30-60 of one result set sorted by a certain column will be totally different than results 30-60 of a result set sorted by a different column. So the paging would have to start over, anyhow. Unless you're looking to maintain the same 30 results in the new result set, like my previous email mentioned... ---John Holmes... > -Original Message- > From: Andre Dubuc [mailto:[EMAIL PROTECTED]] > Sent: Wednesday, June 05, 2002 10:19 PM > To: Miguel Cruz > Cc: [EMAIL PROTECTED] > Subject: Re: [PHP] Modifying the sort order of a query > > Thanks Miguel, > > I haven't tried the sub-query approach yet, but that does seem to be the > way > to do this.

Re: [PHP] Modifying the sort order of a query
Thanks Miguel,
I haven't tried the sub-query approach yet, but that does seem to be the way
to do this. My fear is that it will trash the current paging (which took
forever to get working with the current setup). Actually, after trying my
original code again in another smaller select function, I'm wondering whether
I even need this refined search option -- it might be a case of 'overkill'.
Still, it's got my curiosity going.
The problem seems to be centered on how I wrote the original code (it's
amzing how it's changed!). I think I'll have to re-write using switch
functions to clarify exactly what I want it to do.

Andre

Maybe you could have a hidden field that lists the 30 IDs that are
displayed on the page, as a comma separated list. Then, if the user
chooses to resort those 30 results, based on another column, you can use
that hidden field in your query to limit the IDs.
i.e.
Where the actual numbers would be generated from your result set.
Then, use those numbers in your query.
SELECT * FROM table WHERE ... AND ID IN($display_ids) ORDER BY
<>
Hopefully PG supports IN().
My $0.02, I'm sure there are other ways...or maybe this isn't even what
you're looking for. :)

Re: [PHP] Modifying the sort order of a query
My understanding was that he wanted to see the same 30 rows, but sorted in
a different way.
For instance, he wanted to see entries 30-60 as sorted by age, but to have
those sorted by height when displayed.

Re: [PHP] Modifying the sort order of a query
That's at least curious - limiting and offsetting will most certainly
affect the results which are then sorted... I don't think that's what he

[PHP] Modifying the sort order of a query
Apache 1.3.23 + PHP 4.1.2 + PostgreSQL 7.2
I have a query that sorts by name, country, and city, then pages in groups of
30 records. Originally, I had also coded two buttons: "Sort by Country',
'Sort by City' since I wanted to offer users the options of these choices.
Unfortunately, these buttons work well, but re-select the whole shebang
(which I guess is to be expected), destroying any paging that had already
started. I've tried all sorts of ways, tried re-arranging the order of
execution, but the result is the same.
I'm at a loss on how to proceed. I've deleted the choice (for now) and run it
as a simple select order by name query.The problem seems to be: I need a
sub-query select function that retains the original query, simply
re-organizing it according to the new criteria, and retains the original
paging. (Perhaps I shouldn't care whether the paging is messed up as long as
the results are the same.)
I realize that the way it's set up below, it will automatically send a NEW
query, which is not what I want. I'd like to work with the results of the
original query and modify it with the new criteria
Any suggestions how I can achieve this, or whether it's even possible? I
would greatly appreciate any assistance or comments.

Snippet of offending code:
";
print " ";
print "";
// more code
if($_POST['submit'] == "Sort by Name"){
$query = "SELECT * FROM rap ORDER BY
rsname,rfname,rcountry,rcity,DESC LIMIT 30 OFFSET 30";
}
elseif($_POST['submit'] == "Sort by Country"){
$query = "SELECT * FROM rap ORDER BY
rcountry,rcity,rsname,rfname DESC LIMIT 30 OFFSET 30";
}
//more code, including paging functions
?>
