Hide portion of a widget from author's own profile page - WordPress - wordpress

Question

I'm using a plugin called Widget Logic.
On every author's page I added a contact me form, where you can send the author a message, but I want to hide it if the author is visiting his own profile page.
I see examples like !is_author(), but I don't know how to make the comparison.

You can not do this check with the is_author() function because:
This Conditional Tag checks if an Author archive page is being displayed. This is a boolean function, meaning it returns either TRUE or FALSE.
Of course you can use the is_author() to do the check on a higher level other than the theme template file author.php. For instance when using hooks. Then you could use it.
But I asume you are doing things in the template file, so what you are looking for is something like this:
$current_author = (isset($_GET['author_name'])) ? get_user_by('slug', $author_name) : get_userdata(intval($author));
var_dump($current_author->ID); // < just for you to confirm what value it returns for the current profile you are on
var_dump(get_current_user_id()); // < just for you so you can see what the current user ID is of the user who is logged in at this moment
if( $current_author->ID!=get_current_user_id() ) {
// Display the form...
}else{
// Maybe do something else or do nothing...
}
Update (deregister widget when author ID is same as logged in user ID)
In this example we deregister a Text widget by passing it's class WP_Widget_Text to the unregister_widget() function.
For a full list of WordPress widget class names refer to: https://codex.wordpress.org/Function_Reference/unregister_widget
Put this in your theme functions.php file.
function riseagainst_remove_text_widget() {
// Because `widget_init` is called early, we can not use `get_permalink()`
// neither can we use `home_url( $wp->request )`, neither can we get the
// current author ID at this level when we are on profile page. And we
// need to deregister the widget at this hook, and not at a later stage
// otherwise it will simply override our deregister call to wordpress.
// That's why we will use some of the `$_SERVER` array to obtain the current
// URL (which is provided by the server upon requesting the page).
// We only need the last part of the URL to check if we are on an author page.
$page_url = (isset($_SERVER['HTTPS']) ? "https" : "http") . "://$_SERVER[HTTP_HOST]$_SERVER[REQUEST_URI]";
// The last part of the URL is the author slug in case we are on the author
// profile page. To get the last part of an URL we use `basename()`,
// this will return the slug of the author
$author_name = basename($page_url);
// Now we have the author slug, we can retrieve all author information
// We only need the author ID but this can also be used for other data
// When plain permalink is enabled, we can not search based on slug,
// Instead we will be provided with the author ID via the URL parameter
// named `author`. So do a check on that first
$current_author = ( isset($_GET['author']) ? get_user_by('id', absint($_GET['author'])) : get_user_by('slug', $author_name) );
// This check is important to only execute the code whenever we actually
// are on an author page, when no author was found, we are probably not
// on an author page. (note that if you have problems with it, you can
// also do a check on if the URL path contains `/author/`)
if( $current_author ) {
// Only display the widget whenever current author ID
// is not equal to current logged in user ID
if( $current_author->ID!=get_current_user_id() ) {
// Display the widget...
}else{
// Do not display the widget...
unregister_widget('WP_Widget_Text');
}
}
}
add_action( 'widgets_init', 'riseagainst_remove_text_widget' );
