If you need to theme the node.tpl.php for a specific node, create node-[nid].tpl.php file from node.tpl.php

add to your template.php file

function THEMENAME_preprocess_node(&$variables) {
  
  $node  = $variables['node'];
  if (!empty($node)) {
    $variables['template_files'][] = "node-" . $node->nid;
  }
  
}

We had to use the filepath instead of fid more then once,

Here is a small function we wrote, returning the filepath from the fid

/**  * Get filepath by fid  */ 
function filepath($fid) {   
if (is_numeric($fid)) {     
  $filepath = db_fetch_object(db_query("SELECT filepath FROM files WHERE fid = '%s'", $fid));     
if (is_string($filepath->filepath))       
    return $filepath->filepath;     
  else return FALSE;   
} else return FALSE; 
}

<p>

one of our hosted sites, has start making problems an refused to load the homepage, giving a "not found" error to the browser
looking in the logs, we found this line:

PHP Fatal error: Cannot redeclare product_has_images() ...

after we looked into it, and tried all sort of hooks to catch the cause
of the error, we got a prime-suspect:
the PHP Cache APC

so we restarted apache... and it fixed everything

Working on Linux, we have to use cron to execute jobs such as backups, drupal's search index build and many others.

But how come nothing happens when you run:

 crontab -e 

Many reasons could cause this, but it is most likely that your session's default editor is not installed or somehow ... vanished

Assuming you have vim working on your Linux,

here is how you can change your session's default editor to vim:

 export EDITOR="vim"

 Now, if you type again
