	  $nome_rua = filter_input(INPUT_POST, 'nome_rua', FILTER_SANITIZE_SPECIAL_CHARS);
	  $tiporua = filter_input(INPUT_POST, 'tiporua', FILTER_SANITIZE_SPECIAL_CHARS);
	  
	  
      if($_POST["employee_id"] != '')  
      {  
		$query = "  
			   UPDATE rua   
			   SET   
			   nome='$nome_rua',   
			   tiporua='$tiporua',
			   cod_bairro='$cod_bairro',
			   id_usuario='$id_usuario'
			   WHERE id='".$_POST["employee_id"]."'"
			   ;	
		mysql_query($query,$conexao);	
      }  
      else  
      {  
		$query = "  
			   INSERT INTO rua(nome, tiporua, cod_bairro, id_usuario)  
			   VALUES('$nome_rua', '$tiporua','$cod_bairro','$id_usuario');
			   ";	
		mysql_query($query,$conexao);		   
        $message = 'Data Inserted';

Answer 1

Your id registration button is missing function echo

Wrong:

id="<?php $linha['id']; ?>"

correct:

id="<?php echo $linha['id']; ?>"
