function wpturbo_add_comment_fields( $fields ) {
$fields['wpturbo_comment_subject'] = '<p class="comment-form-subject"><label for="subject">' . __( 'Subject', 'wpturbo' ) . '</label>' .
'<input id="subject" name="subject" type="text" size="30" /></p>';
$fields['wpturbo_comment_rating'] = '<p class="comment-form-rating"><label for="rating">' . __( 'Rating', 'wpturbo' ) . '</label>' .
'<select id="rating" name="rating">
<option value="5">' . __( '5 Stars', 'wpturbo' ) . '</option>
<option value="4">' . __( '4 Stars', 'wpturbo' ) . '</option>
<option value="3">' . __( '3 Stars', 'wpturbo' ) . '</option>
<option value="2">' . __( '2 Stars', 'wpturbo' ) . '</option>
<option value="1">' . __( '1 Star', 'wpturbo' ) . '</option>
</select></p>';
return $fields;
}
add_filter( 'comment_form_default_fields', 'wpturbo_add_comment_fields' );
If you want to add additional input fields to the default comment form in WordPress, this code snippet is perfect for you.
The first part of the code creates a new function called wpturbo_add_comment_fields(). This function will be responsible for adding two new input fields to the default comment form: a Subject field and a Rating field.
The function takes in the $fields variable as a parameter, which contains the default fields for the comment form, and then returns these fields with the new ones included.
Inside the function, we add the Subject field to $fields using the following code:
$fields['wpturbo_comment_subject'] = '<p class="comment-form-subject"><label for="subject">' . __( 'Subject', 'wpturbo' ) . '</label>' .
'<input id="subject" name="subject" type="text" size="30" /></p>';In the above code snippet we’ve added the label, which has an ID of subject, and an input field with a name of subject. This field will give the user the ability to enter a subject for their comment.
Next, we add the Rating field to $fields using this code snippet:
$fields['wpturbo_comment_rating'] = '<p class="comment-form-rating"><label for="rating">' . __( 'Rating', 'wpturbo' ) . '</label>' .
'<select id="rating" name="rating">
<option value="5">' . __( '5 Stars', 'wpturbo' ) . '</option>
<option value="4">' . __( '4 Stars', 'wpturbo' ) . '</option>
<option value="3">' . __( '3 Stars', 'wpturbo' ) . '</option>
<option value="2">' . __( '2 Stars', 'wpturbo' ) . '</option>
<option value="1">' . __( '1 Star', 'wpturbo' ) . '</option>
</select></p>';The code above creates a Rating field with a dropdown that has 5-star rating options. We used the ‘select’ tag to create the dropdown and we’ve linked it up with label, which has an ID of rating.
Finally, we use the add_filter() function to hook the wpturbo_add_comment_fields() function into the comment_form_default_fields filter. This ensures that both the Subject and Rating fields are added to the default comment form.
