How to properly tag topic fields in Drupal 7
I need to view themes in Drupal 7. There is a "Book" content type and I need to list 5 books and their topic in a special way (preview image, title and author).
When I override view-view-field.tpl.php and print the original SQL result, I see that all fields are displayed. This code
echo "<pre>";
print_r($row);
echo "</pre>";
gives
[entity] => stdClass Object
(
[title] => ...
....
[nid] => 34
...
[body] => Array
...
But I don't want to pass the [body] from the database to php because it can be huge and cause a performance problem. I have not selected [body] in the view settings.
Is there a way to only pass certain fields to view-view-field.tpl.php?
Thanks in advance.

If what you want to do is theme of a specific field, you can create a template for that specific field like this: view-view-field - field-nameofmyfield.tpl.php put it in the theme folder and search for templates again in section "Subject: Information" in the "View" configuration.
For this you need to add a field to the fields in the view.

The available variables are recorded in the documentation inside the files in the sites / all / modules / views / theme folder.
Usually the variable that needs to be viewed and changed in the views-view-fields.tpl.php template is $ fields
I am using the devel module (http://drupal.org/project/devel) to view the available variables:
<?php
//after enabling the devel module...
dpm($fields);
// This will print a Kuomo display on the page with the array vars
?>
In general, in terms of nodes,
<?php print $fields['title']->content; ?>
will print the header node. For fields try
<?php print $fields['field_FIELDNAME']->content; ?>
If you have memory, you can grab ALL YOU available on the template in Goomo with
<?php dpm(get_defined_vars()); ?>
Make sure you clear your cache before trying to view vars.

If you want to change the view theme, then change views-view-fields.tpl.php as follows:
<div class="pagecontent">
<div class="colleft">
<?php if($fields['field_file']->content){ ?><div class="views-field-file"><?php print $fields['field_file']->content; ?></div><?php } ?>
</div>
<div class="colright">
<div class="views-field-title"><?php print $fields['title']->content; ?></div>
<div class="views-field-body"><?php print $fields['body']->content; ?></div>
<div class="views-field-view-node"><?php print $fields['view_node']->content; ?></div>
</div>
</div>
