[PHP-DB] result set in php pagination
I am using php and mysql. The problem which I am hoping someone can help me with concerns pagination of the result set of a search of a single table. I got the pagination script I am using from a Sitepoint tutorial and it works just as it should for this query SELECT article_id, category_name, author_name, title, article_caption, date_format(magazine_date, '%M, %Y') as newdate FROM articles where article_id 0 ORDER BY magazine_date DESC LIMIT $offset, $rowsperpage The result set is return over many pages with no problem at all. When it comes to this next query however it delivers the first page of results and sets up the linked pages but those are empty. SELECT article_id, author_name, category_name, title, article_caption, date_format(magazine_date, '%M, %Y') as newdate FROM articles WHERE author_name = '$author_name' ORDER BY magazine_date ASC LIMIT $offset, $rowsperpage I assume the problem must have to do with '$author_name' which is passed to the search script as '$author_name = $_POST[author_name];' from a php form. Is there something I should be doing to ensure that the result set from the query persists though the change in pagination from the first page of results to the second page. In both cases the search scripts are includes in other php pages. I think I need to understand how the result set is carried through or reacquired in the pagination process.

Re: [PHP-DB] result set in php pagination
The easiest thing to do is either A) store the author name in a session for the duration of the searches B) add the name to the pagination url so that its passed along withe the page number On 1/23/10, Joe Keenan heresia...@btopenworld.com wrote: I am using php and mysql.

Re: [PHP-DB] result set in php pagination
I have tried adding the name to the pagination url which gave me http://..results_1.php?currentpage=2author_name=Editorial; Once again no further results were returned. The pagination urls were in place but empty, no pages existed for them. coding sessions in this context is beyond me. Thanks Joe.

Re: [PHP-DB] result set in php pagination
I have tested the script with echo() which shows that the correct
$numrows is returned and then
$totalpages = ceil($numrows / $rowsperpage);
Everything is correct on the first page of results. The pagination
links are displayed correctly but when clicked on the resulting page
is empty.
For some reason I do not understand the result set does not carry
through to the succeeding links in the pagination sequence.
Thanks,
Joe

Re: [PHP-DB] result set in php pagination
This is all that results from the included script on the 2nd display
page:
div id=c-col
div align=center
h3Articles by /h3
h4(There are 0 articles in the database.)/h4
/div
p/p
div align=center
a href='results_1.php?currentpage=2author_name='emNext/em/
a a href='results_1.php?currentpage=0author_name='/a /div
/div
Given that the where clause in the original query is WHERE
author_name = '$author_name' I cannot see how passing the
author_name in the pagination url will help.
Should I somehow pass $author name which was originally picked up from
a form as
'$author_name = '$author_name = $_POST[author_name];'
Clearly I am at a loss here. Could anyone suggest anything in the PHP
Manual, or any tutorial or anything at all on the web about sustaining
a result set through pagination links when the SELECT clause of the
query is modified by a WHERE clause containing a variable.
As it stands I am unable to construct a search engine query to cover
the matter.
Thanks
Joe.

you'll need to add coding to pick up the author too, otherwise the
2nd page won't pick it up and use it.
also, in our link example in an earlier message:

you show two ampersands before author_name. there should only be
one. also, if your author's name includes a space, you'll need to
deal with that.

If you change the $_POST to _REQUEST in this piece of code

Should fix that issue

Re: [PHP-DB] result set in php pagination
Thanks very much Bastien. I haven't the faintest idea why but that
simple change in the code sorted all of this. The pagination links now
follow through with the complete result set of my query.
I will now have to read around this to discover why the change works.
And thanks very much to everyone who took the trouble to reply to my
cry for help. It is all very much appreciated.
