This is just a sample of how you can add PREV NEXT links to your node type template. This function generates links to navigate your nodes in alphabetical order ASC.
Paste this code in your template.php file:
<?php
/**
* ARRAY SEARCH
*/
function multiarray_search($arrayVet, $campo, $valor){
while(isset($arrayVet[key($arrayVet)])){
if($arrayVet[key($arrayVet)][$campo] == $valor){
return key($arrayVet);
}
next($arrayVet);
}
return false;
}
/**
* SIMPLE NEXT PREV BY NODE TYPE
*/
function prev_next_type($id = 1, $direction = 'next', $label = 'next') {
$output = NULL;
$type = db_result(db_query("SELECT n.type FROM {node} n WHERE n.nid = %d",$id));
$result = db_query("SELECT n.nid, n.title FROM {node} n WHERE n.type = '%s' ORDER BY n.title ASC", $type);
while ($row = db_fetch_array($result)) {
$all_nodes[] = $row;
}
$key = multiarray_search($all_nodes,'nid',$id);
$nid = $direction == 'prev' ? $all_nodes[$key-1]['nid'] : $all_nodes[$key+1]['nid'];
$text = $direction == 'prev' ? $all_nodes[$key-1]['title'] : $all_nodes[$key+1]['title'];
if ($nid == null) {
if ($direction == 'prev'){
$nid = $all_nodes[sizeof($all_nodes)-1]['nid'];
$text = $all_nodes[sizeof($all_nodes)-1]['title'];
}else {
$nid = $all_nodes[0]['nid'];
$text= $all_nodes[0]['title'];
}
}
$output = l($label, "node/".$nid);
return $output;
}
?>Paste this code into your node-yourtype.tpl.php file:
<div class="recipe-prev-next">
<div class="recipe-prev"><?php print prev_next_type($nid, $direction = 'prev', $label = 'PREVIOUS'); ?></div>
<div class="recipe-next"><?php print prev_next_type($nid, $direction = 'next', $label = 'NEXT'); ?></div>
</div>
Hello, Pedro,
Very useful snippet, but for most cases
don't forget to include only published nodes,
that is add 'WHERE n.status = 1' to queries
I created a search from views exposed filters. Is there a way that when the user clicks on the node results I can view all the results with Prev Next on that node for that search result?
Thanks,
Prerna
