de mensagem flash aqui<\/a>.<\/p>\n\n\n\nVeja a seguir como usar a fun\u00e7\u00e3o redirection_with_message():<\/p>\n\n\n\n
if(error) {\n redirect_with_message('An error occurred');\n}\n<\/pre>\n\n\n\nA instru\u00e7\u00e3o return encerra o script atual. <\/p>\n\n\n\n
Como todas essas fun\u00e7\u00f5es get_mime_type(), format_filesize() e redirect_with_message() s\u00e3o reutiliz\u00e1veis, voc\u00ea pode adicion\u00e1-las ao arquivo functions.php assim:<\/p>\n\n\n\n
