错误：未定义的偏移量，需要将值传递给Select语句

I'm getting the below error in order to achieve passing values to the "select" statement.

Undefined Offset Error on statement print_r($fieldName[$enID]);

Code looks like

while($row = $result->fetch_assoc()) 
                            {
                                $counter1 = $counter++;     
                                $fieldName[] = $row['fieldName'];
                                $fieldText[] = htmlspecialchars($row['fieldText']);
                                $fieldID[]   = $row['ID'];
                                $enID   = $row['ID'];
                                echo "$enID";
                                print_r($fieldName[$enID]);
//$enfieldText = $mysqli->query("SELECT fieldText FROM languageUpdate WHERE fieldName = '$row["fieldName"]' and Language = 'en'")->fetch_object()->fieldText; ##NEED HELP IN FIXING THIS

                                if ($_GET['showname']){     

                                echo"<tr>";
                                echo "<td>".$row['fieldName']."</td>";
                                echo '<td>'.'<input type = "text" class="form-control" onclick ="colorChange(this)" disabled = "disabled" id ="'.$row["ID"].'"  name = "fieldText['.$row["ID"].']" value = "'.$row["fieldText"].'">'."</td>";
                                echo "</tr>";}


                            }

My code fetches ID, Name and Text from database,and what I'm trying to do is to fetch some another data from the same table but by capturing the Name field extracted earlier. Basically, a nested information is being pulled. I'm getting an undefined offset on line: print_r($fieldName[$enID]). I'm capturing this in order to pass it to the next line to get one unique value, but I'm not able to do so.

example:

Lets say: while fetching results: $fieldName[] Array ( [0] => title [1] => listHeading )

I'm hoping to extract title, and listHeading and pass it to the

//$enfieldText = $mysqli->query("SELECT fieldText FROM languageUpdate WHERE fieldName = 'title'")->fetch_object()->fieldText; ##dynamic parameterization 

Let me know if it is not clear.
