Overview
This Wordpress plugin allows you to add additional fields for users to complete when submitting a comment. The extra data will be saved in the wp database and can be retrieved when showing a post’s list of comments.
The extra comment variables will show up in the list of comments in your Wordpress admin and are editable through the standard admin comment edit page.
This plugin requires a basic knowledge of HTML to modify your comment form.
Example of Use
For this example, we are going to add a field asking for a users age to the comments form.
1. First, add the field to your comments form.
Typically your comments form is in your theme folder and is comments.php
Most likely: (/wp-content/themes/YOURTHEME/comments.php)
Enter the HTML of your new field into the desired spot. To add a textfield for the user to enter their age into, you would add the following to your form. I’ll add mine right below the url textfield.
<p><input type="text" name="age" id="age" size="22" /> <label for="url"><small>Website</small></label></p>
2. Next, we need to add the field-variable to Wordpress.
Inside your Wordpress admin, click the ‘Settings’ menu. Then click the ‘Extra Comment Fields’ menu.
Next, enter the name of the field. This has to be the exact name attribute you gave to the field you added to your comments form. For example, I added this field to my form:
<p><input type="text" name="age" id="age" size="22" /> <label for="url"><small>Website</small></label></p>
The input’s name attribute is ‘age’, so the variable you would enter for this field is ‘age‘.
Note: This can only contain letters, numbers, and/or dashes.
3. Last we want to make use of the data somehow when showing comments.
Your extra fields will be in the $comments variable retrieved by Wordpress. The extra fields you added will have a prefix of ‘extra_’. So to access the data for our ‘age‘ field, we use $comment->extra_age inside the comments loop.
So, for example, if I modify the default theme’s comment.php file, I just insert one line to display the extra comment information (highlighted in bold).
<?php foreach ($comments as $comment) : ?>
<li <?php echo $oddcomment; ?>id=”comment-<?php comment_ID() ?>”>
<?php echo get_avatar( $comment, 32 ); ?>
<cite><?php comment_author_link() ?></cite> Says:
<?php if ($comment->comment_approved == ‘0′) : ?>
<em>Your comment is awaiting moderation.</em>
<?php endif; ?>
<br />
<small class=”commentmetadata”><a href=”#comment-<?php comment_ID() ?>” title=”"><?php comment_date(’F jS, Y’) ?> at <?php comment_time() ?></a> <?php edit_comment_link(’edit’,’ ‘,”); ?></small>
<?php comment_text() ?>
User’s Age is: <?php print $comment->extra_age; ?>
</li>
<?php
/* Changes every other comment to a different class */
$oddcomment = ( empty( $oddcomment ) ) ? ‘class=”alt” ‘ : ”;
?>
<?php endforeach; /* end for each comment */ ?>
</ol>

Important Note When Upgrading from 0.2 to 1
If your Wordpress database tables do not start with ‘wp_’, you will likely need to rename the wp_comments_extra table in your database to match the other table’s prefix. This is a result of the first version incorrectly assuming the prefix across all installations.
For example, if you have have tables named called prefix_posts, prefix_comments, prefix_options, etc then you should rename the wp_comments_extra table to prefix_comments_extra.
