10 items per page (MySQL & PHP)

[queerfm]

Hi i would like to show a max of 10 items per page and i was wondering how is this done.

If you can help that would be great,

$news = "SELECT * FROM news WHERE `group1` LIKE '%".$_GET['g']."%' ORDER BY RAND()";

$result = mysql_query($news);

while($row = mysql_fetch_array($result))
{
    echo "<div class='newslist'><a href='http://www.twitoosearch.com/?p=News&g=view&q={$row['NB']}&tags={$row['group1']}&group={$row['group1']}'><img class='podimg' border='0' alt='{$row['newsname']}' src='{$row['image']}' width='100' height='100' /></a></div>";
}

Any help welcomed

Hi, you would need to put a limit on your MySQL query

$rowsPerPage = 10; //number of results you want to display

$num = 1; //set the offset to start w/the num. of results (good for paging)

$offset = ($num - 1) * $rowsPerPage; // to offset the limit count

$news = "SELECT * FROM news WHERE `group1` LIKE '%".$_GET['g']."%' ORDER BY RAND() LIMIT $rowsPerPage, $offset"; // notice I added the limit

$result = mysql_query($news);

while($row = mysql_fetch_array($result))
{
    echo "<div class='newslist'><a href='http://www.twitoosearch.com/?p=News&g=view&q={$row['NB']}&tags={$row['group1']}&group={$row['group1']}'><img class='podimg' border='0' alt='{$row['newsname']}' src='{$row['image']}' width='100' height='100' /></a></div>";
} 

and the limit can be changed to whatever you want

Thank for the help,
Just a few questions,
Will this show a next button if there are news items that they have not seen, and a back button.

Like i don't want to show a next button if there is nothing to next to.

Tryed the code and seem not to of worked very well, as far as it did not show the limit and when i said 12 it showed 10 and when i said 10 it show 3

What your looking for is known around the developing community as pagination. There are countless articles on how to achieve pagination using PHP and MySQL. I'd recommend you check out a couple of these articles:

PHP Pagination
Pagination through a database
Pagination - what it is and how to do it
Pagination with PHP
How to add paging (Pagination) with PHP and MySQL
PHP pagination script
PHP Pagination Script
Perfect PHP Pagination

Surely one of those can help you.

Note: Is your query fetching random rows? If it is, pagination is impossible. It's just common sense.

No its not well it should not be.

I would like it to be by last entry

however as you can see it seems to be showing the next and back button next to the logos when it should be showing it at the bottom.

here is some of the code

while($row = mysql_fetch_array($SearchResult))
{
    echo "<div class='podcastlist'><a href='http://www.twitoosearch.com/?p=Podcasts&g=view&q={$row['1']}&tags={$row['2']}&group={$row['3']}'><img class='podimg' border='0' alt='{$row['4']}' src='{$row['image']}' width='100' height='100' /></a></div>";

}

$Nav="";
If($page > 1) {
$Nav .= "<br /><A HREF=\"?p=Podcasts&g=" .urlencode($g) . "&page=" . ($page-1) . "\"><< Prev</A>";
}
For($i = 1 ; $i <= $NumberOfPages ; $i++) {
If($i == $page) {
$Nav .= "<B>$i</B>";
}Else{
$Nav .= "<A HREF=\"?p=Podcasts&g=" .urlencode($g) . "&page=" . $i . "\">$i</A>";
}
}
If($page < $NumberOfPages) {
$Nav .= "<A HREF=\"/?p=Podcasts&g=" .urlencode($g) . "&page=" . ($page+1) . "\">Next >></A>";
}
Echo "<div class='searchr'>" . $Nav;
Echo "</div>";
?>

Part of the CSS

div.podcastlist{
	background-image:URL(http://www.twitoosearch.com/images/div.png);
	width:120px;
	float:left;
	position:inherit;
	height:120px;
	margin-right:0.5em;
	margin-bottom:0.5em;
}

div.podcastlist:hover{
	background-image:URL(http://www.twitoosearch.com/images/div_hover.png);
	width:120px;
	height:120px;

}

div.searchr{
	width:100%;
}

Thx
