This is the code I use to create pagination page for data search.But I just noticed that I have too many records then it will have too many page numbers.I’m trying to limit the page number shown,and look for many examples ..it have many ways to do it but I still don’t have idea how to limit it for my method…

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; ?>
