<?php
if(isset($_POST['num'])){
$num=$_POST['num'];
for ($i=1; $i <=$num ; $i++) {
echo "<tr>
<td><label>OPTION " . $i . "</label></td>
<td><input class='form-control' name='txtoptname[]'></td>
<td></td><td></td>
</tr>";
}
}
?>
<tr>
<tr>
<td colspan=6><button class="btn btn-success btn-lg btn-block" type="submit" >ADD QUESTION NO. 1</button></td>
</tr>
</form>

qtableadddb.php

if(isset($_POST["txtoptname"]) && is_array($_POST["txtoptname"])){  
$capture_field_vals ="";

Hi can you try this one

VALUES ('$qno','$i',UPPER('$text_field'),0); convert to 


VALUES ($qno,$i,UPPER($text_field),0);
