For Acidfree images
Last modified: August 26, 2009 - 23:58
Here is the code to add next, previous buttons to acidfree images. The images are ordered according to weightings. Place the code in template.php in your theme directory. (I know, I know, i'm supposed to use joins...). It works for both images and videos in acid free.
<?php
function next_prev_acidfree($current_nid, $label, $class) {
# get its parent
$query = db_query("SELECT parent FROM `acidfree_hierarchy` WHERE child = $current_nid;");
$parent = db_result($query);
# root gallery
if ($parent == -1) {
$arr ['parent'] = l("Photo Gallery", 'acidfree', array("title" => $label, "class" => $class));
}else {
# Get the parent
$query = db_query("SELECT title FROM `node` WHERE nid = $parent;");
$parent_title = db_result($query);
$arr ['parent'] = l($parent_title, 'node/'.$parent, array("title" => $label, "class" => $class));
}
# Get all the other photos videos that have the same parent
//$sql = "SELECT n.nid, n.title FROM {node} n INNER JOIN {term_node} t ON n.nid = t.nid ";
$sql = "SELECT a.aid, n.title, nid FROM {node} n, {acidfree} a, {acidfree_hierarchy} ah ".
" WHERE n.type='acidfree' AND n.nid = a.aid AND (a.class='photo' || a.class='video')".
" AND ah.parent = $parent AND ah.child=a.aid ".
" ORDER BY a.weight ASC, n.nid DESC";
$result = db_query($sql);
if (!db_num_rows($result)) {
$arr ['next'] = null;
$arr ['previous'] = null;
} else {
while ($row = db_fetch_array($result)) {
if ($row['nid'] == $current_nid && $before) {
$arr ['previous'] = l("< < Previous", "node/".$before['nid'], array("title" => $label, "class" => $class));
}
if ($before['nid'] == $current_nid) {
$arr ['next'] = l("Next > >", "node/".$row['nid'], array("title" => $label, "class" => $class));
}
$before = $row;
}
}
return $arr;
}
function phptemplate_display_next_previous($node) {
$arr = next_prev_acidfree($node->nid, 'Navigation', 'test');
//echo $previous . " | " . $next ."";
$output .= "<table class='acidfree-next-previous'>";

theme('image', _acidfree_get_small_url($node),
