How to see available template variables in Drupal
Thu, 02/04/2010 - 03:55
Drupal's phptemplate engine has several template files and each file has several available variables. They are generally used printing their values. But, if you are bit more tricky, you can also utilize their values in various different approaches.
Viewing available variables:
There is a very simple PHP function to print available variables.
Code is:<?php var_dump(get_defined_vars()); ?>
Simple use it in your template file in which you want to see variables. For an instance, I did it on node.tpl.php and I got following variables:
Output:<?php array(50) { ["template_file"]=> string(36) "sites/all/themes/crusti/node.tpl.php" ["variables"]=> array(48) { ["nid"]=> string(2) "16" ["type"]=> string(5) "story" ["language"]=> string(0) "" ["uid"]=> string(2) "19" ["status"]=> string(1) "1" ["created"]=> string(10) "1259101383" ["changed"]=> string(10) "1265259608" ["comment"]=> string(1) "2" ["promote"]=> string(1) "1" ["moderate"]=> string(1) "0" ["sticky"]=> string(1) "0" ["tnid"]=> string(1) "0" ["translate"]=> string(1) "0" ["vid"]=> string(2) "16" ["revision_uid"]=> string(1) "1" ["title"]=> string(18) "Example note title" ["body"]=> string(296) "<p>node (story) - Eros turpis probo distineo pala pala molior comis utinam.

For example, you can determine the current comment status of a node by viewing $comment variable.
<?php $comment = 0; // Comment is disabled $comment = 1; // Comment is Read only $comment = 2; // Comment is set to Read/Write ?>
