<?php echo esc_attr( get_bloginfo( 'title' ) ) ); ?> kullanmak için

şöyle bir functions.php oluşturdum:


function get_header_image() {
$url = get_theme_mod( 'header_image', get_theme_support( 'custom-header', 'default-image' ) );

if ( 'remove-header' == $url ) {
return false;
}

if ( is_random_header_image() ) {
$url = get_random_header_image();
}
}
?>


şöyle hata alıyorum:

Fatal error: Cannot redeclare get_header_image() (previously declared in C:\Program Files (x86)\EasyPHP-Devserver-17\eds-www\wordpress\wp-includes\theme.php:1058) in C:\Program Files (x86)\EasyPHP-Devserver-17\eds-www\wordpress\wp-content\themes\html5blank-stable1\html5blank-stable\functions.php on line 13
