Wordpress将输入字段中的值设置为登录用户的评论作者

Question

I have a shared account, lets call it "marketing". Now I have three people using this account named Anna, Ben and Max.

When someone logs into this account and wants to type a comment with their name, it always shows the name "marketing" as author. How can I change this so that I put a name in my input field and I get the value from this as my comment author. In my comments.php I do not check if the user is logged on and call it here:

<input type="text" name="author" id="author" value="<?php echo $comment_author; ?>" size="22" tabindex="2"/>

I tried to make following in my functions.php:

function change_author( $commentdata ) {
    if ( $commentdata['user_ID'] == 2 ) {  // User ID for Marketing

    $commentdata['user_ID'] = 0; 
    $commentdata['comment_author'] = '';

  }

  return $commentdata;
}
add_filter( 'preprocess_comment' , 'change_author' ); 

In this case my comment_author will always be Anonymous and also if I set it to NULL.

When i give the variable a value $commentdata['comment_author'] = 'test'; I get "test" as my comment_author but as I said, I would like to have the value I set in my input field. It works for not logged in users very well so I thought there might be a trick for logged in users as well.

In phpMyAdmin I checked for the entries in the database and it is giving me the right values for ID etc. But it also empties the comment_author field which results in an anonymous author.

I really hope that somebody can give me the right hint to accomplish this task.

Goddamit, I didn't know that this was so f***ing easy.

function change_author( $commentdata ) {

    if ( $commentdata['user_ID'] == 2 ) { 

    $commentdata['user_ID'] = 0;
    $commentdata['comment_author'] = $_POST['author'];
    $commentdata['comment_author_email'] = '';
    $commentdata['comment_author_url'] = '';

  }

  return $commentdata;
}
add_filter( 'preprocess_comment' , 'change_author' ); 

I think this would work also with != 0 instead of == 2. This is just a solution for my custom theme but I think it would also work with

$commentdata['comment_author_email'] = $_POST['mail'];
$commentdata['comment_author_url'] = $_POST['url'];

Note: the value in $_POST[] is either the name or the ID from the input field. Didn't test everything because name and ID have the same value in my theme.

Tested it a few times local and it worked very well!
