Wordpress Media Count and Next Page Navigation - php

Question

Users are allowed to upload and access media files from front end. I am using following code which retrieve media files and show on user front end. I have 40 media files in my wordpress uploads but I want to show e.g. 20 media files at single page and I wonder if someone can help to write previous & next page navigation code for media files. e.g Page 1 2 3 ... 10
<?php
$args = array(
'post_type' => 'attachment',
/* 'posts_per_page' => '2', */
'numberposts' => -1,
'post_status' => null,
'author' => $current_user->ID,
'post_parent' => $post->ID,
'caller_get_posts'=> 1,
);
$attachments = get_posts( $args );
if ($attachments) {
foreach ($attachments as $attachment) {
echo '<tr><td><a href="'.wp_get_attachment_url($attachment->ID).'" rel="shadowbox" title="'.$attachment->post_excerpt.'">';
echo ($attachment->_wp_attached_file);
echo '</a>
</td>
</tr>';
}
?>

Answer 1

You can try to use the standard wordpress navigation.
Try to change your $args like this:
$paged = (get_query_var('paged')) ? get_query_var('paged') : 1;
$args = array(
'posts_per_page' => 20,
'paged' => $paged
);
UPDATE:
<?php
$paged = (get_query_var('paged')) ? get_query_var('paged') : 1;
$args = array(
'post_type' => 'attachment',
'posts_per_page' => 20,
'paged' => $paged,
'numberposts' => -1,
'post_status' => null,
'author' => $current_user->ID,
'post_parent' => $post->ID,
'caller_get_posts'=> 1,
);
$attachments = get_posts( $args );
if ($attachments) {
foreach ($attachments as $attachment) {
echo '<tr><td><a href="'.wp_get_attachment_url($attachment->ID).'" rel="shadowbox" title="'.$attachment->post_excerpt.'">';
echo ($attachment->_wp_attached_file);
echo '</a>
</td>
</tr>';
}
?>
UPDATE 2
Also you need to use this function
Post it somewhere below your posts
$big = 999999999; // need an unlikely integer
$navArgs = array(
'base' => str_replace( $big, '%#%', esc_url( get_pagenum_link( $big ) ) ),
'format' => '?page=%#%',
'total' => 1,
'current' => max( 1, get_query_var('paged') ),
'show_all' => False,
'end_size' => 1,
'mid_size' => 2,
'prev_next' => True,
'prev_text' => __('« Previous'),
'next_text' => __('Next »'),
'type' => 'plain',
'add_args' => False,
'add_fragment' => '',
'before_page_number' => '',
'after_page_number' => ''
);
echo paginate_links( $navArgs );
As you can see you can set navArgs the way you like.
You need to get a total count of your posts and set the 'total' parameter.

Finally I wrote my solution
<?php
$paged = ( get_query_var('page') ) ? get_query_var('page') : 1;
$args = array(
'post_type' => 'attachment',
'posts_per_page'=> '10',
'paged' => $page,
'numberposts'=> -1,
'post_status' => 'any',
'author' => $current_user->ID,
'post_parent' => $post->ID,
'caller_get_posts'=> 1,
'number' => $display_count,
);
// Custom query, display posts by args defined users
$file_query = new WP_Query( $args );
$attachments = get_posts( $args );
if ($attachments) {
foreach ($attachments as $attachment) {
echo '<tr><td><a href="'.wp_get_attachment_url($attachment->ID).'" rel="shadowbox" title="'.$attachment->post_excerpt.'">';
echo ($attachment->_wp_attached_file);
echo '</a>
</td>
</tr>';
}
}
?>
Call query funtion in in your code
<?php previous_posts_link( '<< Previous Page', $file_query->max_num_pages ); ?> | <?php next_posts_link( 'Next Page >>', $file_query->max_num_pages ); ?>
