Separate theme for a specific node
If you want to use a specific node.tpl.php for a node, paste or merge this code into your template.php:
<?php
function _phptemplate_variables($hook, $vars = array()) {
switch ($hook) {
case 'node':
$vars['template_files'] = array('node-'. $vars['nid']);
break;
}
return $vars;
}
?>You can now for example create files named node-34.tpl.php to create a custom theme for just the node 34.
Drupal 6 solution:
This method does not work in Drupal 6 as _phptemplate_variables() is no longer available.
I tried inserting this code into my template.php file:
<?phpfunction phptemplate_preprocess_node(&$vars) {
$vars['template_files'] = array('node-'. $vars['nid']);
return $vars;
}
?>
Then you can then name node specific template variables as in the above article - but then you can no longer theme by content type... so it's not a proper solution...
After fiddling around for a while, I got something better:
<?php//allows node specific themes.
function phptemplate_preprocess_node(&$variables) {
$potentialNodeSpecificTemplate = 'node-'. $variables['nid'];
//check if there is a node specific template.
$potentialNodeSpecificTemplateFile = path_to_theme()."/".$potentialNodeSpecificTemplate.".tpl.php";
if (file_exists($potentialNodeSpecificTemplateFile)) {
//use this template file.
$variables['template_files'] = array($potentialNodeSpecificTemplate);
}
return $variables;
}
?>
This function checks to see if there is a node specific template file and if it finds one loads it. If it isn't there it does nothing, thus solving the problem the first function encountered.
Better
<?phpfunction phptemplate_preprocess_node(&$vars) {
$vars['template_files'][] = array('node-'. $vars['nid']);
return $vars;
}
?>
This avoids overwriting the existing content of $vars['template_files'] (which should be an array containing 'node-nodetype'), and hence the more complex code is then not needed. Actually, Drupal 6 info on template suggestions is here ... http://drupal.org/node/223440
