Show info to author only

Question

I'm writing my own plugin.

works like this:

function myfunc (){
    $a = 'hello';
    // the sentence what Am looking for: 
    if ( user is logged and is the author of current post / page ){
        $a= 'author';
    }
    return $a; 
}

Wondering how I can do that sencence / function?

Answer 1

Just compare display names:

$currentuser = get_currentuserinfo();

if ( get_the_author() == $currentuser->displayname ) {
     // current user is the post author; do something
}

The get_the_author() function returns displayname, which should be able to be compared against the displayname parameter that is a part of the $currentuser object.

Answer 2

You can get this information using the current_user and post variables.

function myfunc (){
    global $current_user, $post;
    $a = 'hello';
    // check if current user id matches post author id
    if ( $current_user->ID == $post->post_author ){
        $a = 'author';
    }
    return $a; 
}
