Displaying WordPress Media IDs in the Admin

Id of media files can be found, if in the admin panel in paragraph Media display all media files and point to the point Edit, but there is an easier way.

You can display id in a separate column. To display id media files in the admin panel, as a separate column, you can use the following filter. Add code to function.php.

function column_id($columns) {
    $columns['colID'] = __('ID');
    return $columns;
}
add_filter( 'manage_media_columns', 'column_id' );
function column_id_row($columnName, $columnID){
    if($columnName == 'colID'){
       echo $columnID;
    }
}
add_filter( 'manage_media_custom_column', 'column_id_row', 10, 2 );

function column_id($columns) {

$columns['colID'] = __('ID');

return $columns;

}

add_filter( 'manage_media_columns', 'column_id' );

function column_id_row($columnName, $columnID){

if($columnName == 'colID'){

echo $columnID;

}

add_filter( 'manage_media_custom_column', 'column_id_row', 10, 2 );

We replace the standard jquery library with the one suggested by google

If you, for some reason, the standard package of the jquery library that WordPress offers us is not satisfied, you can connect the library from google. Adding code to the function.php file.

add_action( 'init', 'jquery_register' );
function jquery_register() {
if ( !is_admin() ) {
    wp_deregister_script( 'jquery' );
    wp_register_script( 'jquery', ( 'https://ajax.googleapis.com/ajax/libs/jquery/1.6.2/jquery.min.js' ), false, null, true );
    wp_enqueue_script( 'jquery' );
   }
}

add_action( 'init', 'jquery_register' );

function jquery_register() {

if ( !is_admin() ) {

wp_deregister_script( 'jquery' );

wp_register_script( 'jquery', ( 'https://ajax.googleapis.com/ajax/libs/jquery/1.6.2/jquery.min.js' ), false, null, true );

wp_enqueue_script( 'jquery' );

}

Removing the Editor item from the Apperance menu:

function remove_editor_menu() {
  remove_action('admin_menu', '_add_themes_utility_last', 101);
}
add_action('_admin_menu', 'remove_editor_menu', 1);

function remove_editor_menu() {

remove_action('admin_menu', '_add_themes_utility_last', 101);

}

add_action('_admin_menu', 'remove_editor_menu', 1);

Hide pages from the admin from editing

This is a great little snippet., which will exclude pages, selection is based on ID from the list of pages. Just add this snippet to functions.php your topic WordPress and try to find those pages ID who you tried to hide.

add_action( 'pre_get_posts' ,'exclude_this_page' );
function exclude_this_page( $query ) {
        if( !is_admin() )
                return $query;
        global $pagenow;
        if( 'edit.php' == $pagenow && ( get_query_var('post_type') && 'page' == get_query_var('post_type') ) )
                $query->set( 'post__not_in', array(23,28,30) ); // page id
        return $query;
}

add_action( 'pre_get_posts' ,'exclude_this_page' );

function exclude_this_page( $query ) {

if( !is_admin() )

return $query;

global $pagenow;

if( 'edit.php' == $pagenow && ( get_query_var('post_type') && 'page' == get_query_var('post_type') ) )

$query->set( 'post__not_in', array(23,28,30) ); // page id

return $query;

}
