Virtual Pagination with Mysql??

[jnscollier]

1) Script Title:
Virtual Pagination Script

2) Script URL (on DD):
http://www.dynamicdrive.com/dynamicindex17/virtualpagination.htm


3) Describe problem:
I love this script and in essence it would do exactly what I want, except... here's what I'm trying to do....

I want to display comments on the bottom of my page and the comments are being pulled from a mysql table. I'd like users to be able to flip through the comments (next, prev, page numbers) without the top of the page reloading. I have tried regular pagination and it reloads the whole page, I don't want that. I just want the bottom of the page to change with the new content... Can someone please help???? I'm using php.

Please let me know if I need to provide more clarification. ANY help would be GREATLY appreciated because I'm going insane. :eek:

Try something like this:




<div style="width: 400px; height: 250px">

<?php
include('dbconnect.php'); //this will have you connection details.

$comments = mysql_query("SELECT * FROM `comments`");

while ($q = mysql_fetch_array($comments)) {
?>

<div class="virtualpage">

<?php echo $q['comments'];?>

</div>

<?php
}
?>

</div>


This is just an example of what how you could do this. Hope this helps.

Yeah, I got it this far, it shows every single comment on a separate page though, how can I make it so it shows first 15 comments on page 1, page 2 has comments 16-30, etc?

ok, try this:



<?php
include('dbconnect.php'); //this will have you connection details.

$pp = "15"; //total comments per page

$total_comments = mysql_query("SELECT * FROM `comments`");
$total =mysql_num_rows($total_comments);

$total_pages = floor($total/$pp);

for ($i=0; $i<=$total_pages; $i++) {
$start = $pp * $i;

$comments = mysql_query("SELECT * FROM `comments` LIMIT $start, $pp");

echo '<div class="virtualpage">';

while ($q = mysql_fetch_array($comments)) {
?>

<div><?php echo $q['comments'];?></div>

<?php

echo '</div>';
}
}
?>


Not tested with the mysql aspect, but should work.

Hope this helps.

<div style="width: 400px; height: 700px;">
<?php
include('dbconnect.php'); //this will have you connection details.

$pp = "15"; //total comments per page

$total_comments = mysql_query("SELECT * FROM ".COMMENTS."");
$total =mysql_num_rows($total_comments);

$total_pages = ceil($total/$pp);

for ($i=0; $i<=$total_pages; $i++) {
$start = $pp * $i;

$comments = mysql_query("SELECT * FROM ".COMMENTS." LIMIT $start, $pp");

echo '<div class="virtualpage">';

while ($q = mysql_fetch_array($comments)) {


$test = $q['comment'];
?>

<div><?php echo $test;?></div>

<?php

echo '</div>';
}
}
?>

</div>


<!-- Pagination DIV for Demo 1 -->
<div id="gallerypaginate" class="paginationstyle">
<a href="#" rel="previous">Prev</a> <span class="flatview"></span> <a href="#" rel="next">Next</a>
</div>

<!-- Initialize Demo 1 -->
<script type="text/javascript">
var gallery=new virtualpaginate("virtualpage", 1)
gallery.buildpagination("gallerypaginate")
</script>



It just displays all 27 comments on the first page.... second page and third page... I'm at a complete loss. Thank you for the help testingsite... i don't know what else to do !!!!!!!!!!!!!!!!!!!!!!

Can you post a link to the problem page, I think I see what the problem is in the code, but I just want to make sure. Either way, try changing this part:



<?php

echo '</div>';
}
}
?>


to this:



<?php
}

echo '</div>';

}
?>


Notice how the closing div is below the first closing bracket. Try that, and if that still doesn't work, post (or PM) the link, and I'll take a look at it.

Worked GREAT.... thanks for everything testingsite, it was displaying an extra page though, all i had to do was remove the ceil

[thetestingsite]

ok...thanks, I will note it for next time. Glad to hear it is working for you.

how would i apply the mysql and php code to this script http://www.dynamicdrive.com/dynamicindex17/ajaxpaginate/index.htm ?

I currently have a page that displays over 100 user images with user names next to them from a mysql php query code. I would love to be able to setup a pagination that would allow me to display 20 at a time from the query.
