Display edit link if post author is current user

Question

I am creating an author.php page and listing all the posts from an author. Although admins can see the posts' edit links i want to echo the link if logged in user is the current user

for example

if testuser is logged in and current page is /author/testuser he can see edit post links

but

if testuser is logged in and current page is /author/theee he cant see the links

currently i have

$curauth = (isset($_GET['author_name'])) ? get_user_by('slug', $author_name) : get_userdata(intval($author));
$th = $curauth->nickname; 
$cu = $current_user->user_login;
if ( $th = $curauth ) {
  edit_post_link('edit', '', ''); 
} else {

}

but still only admins can see the links.

Answer 1

If you just have to modify the author.php page, this piece of code will probably work :

<?php 

if( is_user_logged_in() && is_author(get_current_user_id()) ) {

    edit_post_link('edit', '', '');

}

?>

The first part of the conditions checks if there is a user logged. The second one will be true if the current page is the author page of the current user.

I think the post edit link should be visible to post author and moderator(editor user or how have that capability)

So my proposed code is like this

global $post;
$current_user = wp_get_current_user();

if(current_user_can( 'edit_others_posts', $post->ID ) && ($post->post_author == $current_user->ID))  { 

    //show edit link    
}

Placed in your theme's functions.php this should globally alter the behavior of edit_post_link. It should work on all of your archives, not just your author archives-- anything that uses edit_post_link.

function limit_edit_Link_wpse_85214($link) {
  global $post,$current_user;
  get_currentuserinfo();
  if ($post->post_author == $current_user->ID) {
    return $link;
  }
  return false;
}
add_filter('get_edit_post_link','limit_edit_Link_wpse_85214');

If will only work reliably inside a Loop, which is the only place you should be using edit_post_link anyway.

If you want this to work only for your author archive pages, just paste that code before the Loop in the author.php template and don't put it in function.php. It shouldn't effect anything but that page then. Or you can just use the guts for the function to make your conditional, like you were trying to do.

I could not get the @Mat solution to work. It looks correct, however.

WP stores the value of $post->post_author as a string. However, get_the_author_meta( 'ID' ) and get_current_user_id() each return an integer, so strict comparison works in the second part of the IF statement.

If you replace get_the_author_meta( 'ID' ) with $post->post_author you must use == and not === as the comparison operator because the value of $post->post_author is a string and get_current_user_id() returns an integer.

Test:

<?php echo 'Author ID type: ' . gettype( get_the_author_meta( 'ID' ) ) . '<br>'; ?>
<?php echo 'Current user ID type: ' . gettype( get_current_user_id() ); ?>
<?php 
    echo 'Is logged in user the author? '; 
    if ( get_the_author_meta( 'ID' ) == get_current_user_id() ) {
         echo 'TRUE  <br>'; 
    } else {
        echo 'FALSE'; 
    }
?>

Solution using strict comparison operator that works for me:

<?php if ( is_user_logged_in() && get_the_author_meta( 'ID' ) === get_current_user_id() ) : ?> 

  //...

<?php endif; ?>
