Ok, hvis du mener vis noget lignende

Det første, vi skal, er at oprette en funktion, der kan behandle det, vi skal bruge for at udskrive pagineringen. Her er en funktion, jeg bruger, og den fungerer godt.
function get_paging_info($tot_rows,$pp,$curr_page)
{
$pages = ceil($tot_rows / $pp); // calc pages
$data = array(); // start out array
$data['si'] = ($curr_page * $pp) - $pp; // what row to start at
$data['pages'] = $pages; // add the pages
$data['curr_page'] = $curr_page; // Whats the current page
return $data; //return the paging data
}
Nu er denne funktion ret solid og fungerer meget godt for mig.
Så du består denne funktion
- $tot_rows =talte rækker til forespørgsel
- $pp =elementer pr. side
- $curr_page =det aktuelle sidetal
Ok, nu hvor du har de data, du har brug for, bliver du nødt til at vise dem.
Her er, hvad jeg bruger, og læs det, før du tænker, 'åh, det er for langt'. Det er faktisk meget enkelt.
Her er et øjebliksbillede af, hvad det vil returnere
<!-- Create the query -->
<?php $count = mysql_fetch_assoc( mysql_query ( "SELECT COUNT( rows ) as count FROM table" ) ) ;
<?php $count = $count[0]['count']; ?>
<!-- Call our function from above -->
<?php $paging_info = get_paging_info($count,5,34); ?>
<p>
<!-- If the current page is more than 1, show the First and Previous links -->
<?php if($paging_info['curr_page'] > 1) : ?>
<a href='' title='Page 1'>First</a>
<a href='' title='Page <?php echo ($paging_info['curr_page'] - 1); ?>'>Prev</a>
<?php endif; ?>
<?php
//setup starting point
//$max is equal to number of links shown
$max = 7;
if($paging_info['curr_page'] < $max)
$sp = 1;
elseif($paging_info['curr_page'] >= ($paging_info['pages'] - floor($max / 2)) )
$sp = $paging_info['pages'] - $max + 1;
elseif($paging_info['curr_page'] >= $max)
$sp = $paging_info['curr_page'] - floor($max/2);
?>
<!-- If the current page >= $max then show link to 1st page -->
<?php if($paging_info['curr_page'] >= $max) : ?>
<a href='' title='Page 1'>1</a>
..
<?php endif; ?>
<!-- Loop though max number of pages shown and show links either side equal to $max / 2 -->
<?php for($i = $sp; $i <= ($sp + $max -1);$i++) : ?>
<?php
if($i > $paging_info['pages'])
continue;
?>
<?php if($paging_info['curr_page'] == $i) : ?>
<span class='bold'><?php echo $i; ?></span>
<?php else : ?>
<a href='' title='Page <?php echo $i; ?>'><?php echo $i; ?></a>
<?php endif; ?>
<?php endfor; ?>
<!-- If the current page is less than say the last page minus $max pages divided by 2-->
<?php if($paging_info['curr_page'] < ($paging_info['pages'] - floor($max / 2))) : ?>
..
<a href='' title='Page <?php echo $paging_info['pages']; ?>'><?php echo $paging_info['pages']; ?></a>
<?php endif; ?>
<!-- Show last two pages if we're not near them -->
<?php if($paging_info['curr_page'] < $paging_info['pages']) : ?>
<a href='<?php echo str_replace('/page'.$paging_info['curr_page'], '', $paging_info['curr_url']) . '/page'.($paging_info['curr_page'] + 1); ?>' title='Page <?php echo ($paging_info['curr_page'] + 1); ?>'>Next</a>
<a href='<?php echo str_replace('/page'.$paging_info['curr_page'], '', $paging_info['curr_url']) . '/page'.$paging_info['pages']; ?>' title='Page <?php echo $paging_info['pages']; ?>'>Last</a>
<?php endif; ?>
