The Pear Pager class works like a champeen, too. It'll paginate results however you'd like it to. ~Rob Chris W.

Re: [PHP] Re: google style paginating
IMHO a PEAR pager package sounds like a sledgehammer when all that's needed is a hammer. Cheers, Rob.

[PHP] Re: google style paginating
just split up your total number of results ($num_rows) by the results per
page (10, i think) and create a for loop to loop from page1 to pagex,
creating a link with offset for each one.
simple.

Hi I am new to this newsgroup and I plan on replying to all the posts I
can
for now... but Id like to start out by asking a question. I am trying to
paginate my sql results in 10 by 10, which I have been able to do no
problem. but what I want to do is have the pages layed out in google style
with (1)(2)(3)(4) etc etc and each one is clickeable that will take you to
that page. I'll show you the code I am using now for next and back
buttons...
//located at top of page
?php
include(include/conex.php);
$link=Conectarse();
?
//start of body, this verifies that so is numeric, divisible by 10, and a
valid number
?php
$q=SELECT id FROM tblNoticias ORDER BY id ;
$result=MYSQL_QUERY($q,$link);
$num_rows=(MYSQL_NUM_ROWS($result));
if ( isset($_GET['so']) is_numeric($_GET['so']) )
{
if ( ($_GET['so'] $num_rows) || ($_GET['so'] 0) )
$so='0';
else
{
if ($_GET['so'] % 10)
$so='0';
else
$so=$_GET['so'];
}
}
else
$so='0';
?
//return results
?php
$q=SELECT id,titulo,texto,img1_data FROM tblNoticias ORDER BY id DESC
LIMIT
$so,10;
$result=(MYSQL_QUERY($q,$link));
while ($row=(MYSQL_FETCH_ARRAY($result))){
?
// next and back buttons
?PHP
if ( $so =10)
{
$sortback= $so-10;
echo A HREF=\noticias_historia.php?so=$sortback\
class=\mainText\
Atras/A ;
}
?
?PHP
$sortforth=$so + 10;
$existencias=MYSQL_QUERY(SELECT id FROM tblNoticias LIMIT
$sortforth,10,$link);
$existencias=MYSQL_NUM_ROWS($existencias);
if ( $existencias 0 )
echo A HREF =\noticias_historia.php?so=$sortforth\
class=\mainText\ Siguiente /A;
?
DID I PUT WAY TO MUCH CODE?? Sorry, and I apreciate your help.
How can I implement the google style paging into this code?
Thank you...

Re: [PHP] Re: google style paginating
Ummm I wouldn't do what these guys suggest (at least not all of it)...
perform two queries, one counting the total number of returns the other
to actually get the subset. Don't retrieve ALL the queries then only
display a subset. Otherwise what's the point of using the LIMIT clause
for conservation of resources? The SELECT COUNT( * ) FROM foo query is
usually optimized to be extremely fast so the first query is almost
negligible in contrast to the second.
Cheers,
Rob.
