破碎的分页

Question

I've been slamming my head against a wall trying to figure this out but can't seem to get a solution. I have offset defined as 0 but in my pagination links offset+1 for older posts just leads to an error page. Not really sure where I'm going wrong. Any help would be appreciated.

Here is all the code from my page.php file...

<?php

$offset = $_GET['offset'] ? $_GET['offset'] : 0;

$page_title = $wp_query->post->post_title;
$total_posts = wp_count_posts()->publish;

if ( $page_title == "Blog" ) {

?>
<div id="blog_content">
<?php
    if($_GET['message']){
        echo "<div style='background-color:#d9ffd1; padding:10px; margin-bottom:20px;'>".stripslashes($_GET["message"])."</div>";
    }
?>

<?php
    $post_count = 0;

    $args = array( 'numberposts' => 10, 'post_status' => "publish", "offset"=>$offset*10);
    $myposts = get_posts( $args );
    foreach( $myposts as $post ) :  setup_postdata($post); $post_count++; ?>

And then my pagination links

<div style="font-size:12px;">
        <div style="float:left; width:49%;">
        <?php
        the_post();

            if ($offset > 0): ?>
        <a href="<?php the_permalink()?>&offset=<?=$offset-1?>">&larr; Newer Posts</a>
        <?php endif; ?>
        </div>
        <div style="float:right; width:49%; text-align: right;">
        <?php
        $next_post = get_next_post();
        if ($total_posts > $post_count + ($offset*10)): ?>
        <a href="<?php the_permalink()?>&offset=<?=$offset+1?>">Older Posts &rarr;</a>
        <?php endif; ?>
        </div>
        <div style="clear:both;"></div>
    </div>

Thanks in advance for any help anyone can provide

Its not entirely clear on what you are trying to achieve, but I think you want to look closely at http://codex.wordpress.org/Making_Custom_Queries_using_Offset_and_Pagination

Specifying hard-coded offsets in queries can and will break pagination since offset is used by WordPress internally to calculate and handle pagination.

To get around this limitation, you will need to write some additional code to manually handle pagination; you need to detect whether a loop has additional pages and then dynamically calculate the appropriate offset for the current page.

The code for controlling custom pagination will all occur within your functions.php file and not within the template page.php You can set an initial offset, as well as redefine the number of posts per page. There are specific samples displayed on the codex link above.

You will be adding the action before the query is run, via

   add_action('pre_get_posts', 'myprefix_query_offset', 1 );

and you will have to account for the customization via

   add_filter('found_posts', 'myprefix_adjust_offset_pagination', 1, 2 );
