"limit pagination page number" Answer’s

0

Ok if you mean show something like

Prev 1 2 3 4 5 6 .. 40 41 Next 
Prev 1 2 .. 6 7 8 9 10 .. 40 41 Next

First thing we need to is create a function that can process what we need to output the pagination. Heres a function I use and it works well.

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

}

Now this function is pretty solid and works very well for me.

So you pass this function

  • $tot_rows = counted rows for query
  • $pp = items per page
  • $curr_page = the current page number

Ok, now that you have the data you need, you'll need to display it.

Heres what I use and please read it before you think, 'ah, it's too long'. It's actually very simple.

Heres a snapshot of what it will return

    <!-- 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; ?>
