Get a list of field variables for template code

Question

For Drupal 7, how do I access (or generate) a list of all the field variables available for building a template (for a given content type)?

Some context: I used to rely on the (now deprecated) Contemplate module to write my templates. Directly within its interface, it would print a list of all of the available variables, like this.

It was quite handy. Now that I'm making disk-based templates and do not have this list generated by the Contemplate module, I'm confused as to how I might produce something similar for use as a reference.

Use Devel module and then with using get_defined_vars you can get a list of defined variables. then in you template file use the following snippet

<?php
 dsm(get_defined_vars()); 
// or even  dsm(get_defined_vars()); 
?>

and another solution is based on hook_preprocess. just dumps the variables there.

on your template.theme file

mymodule_preprocess(&$vars, $hook) {
dpm($vars);
}

**Update* if you want to see the $variables on node template try on your template.

copy/paste this snippet on your template.php then clear the cache function YOURTHEMENAME_preprocess_node(&$variables) { dpm($variables); // you can add or remove whatever you want to it here }

if your theme name is themetastic So

function themetastic_preprocess_node(&$variables) {
    dpm($variables);
    // you can add or remove whatever you want to it here
}
