I answered you. You have to simply change the code like this -
Change <form></form> code -
form></form> code -
<form action="" method="post" name="form1">
<table width="25%" border="0">
<tr>
<td>RollNo</td>
<td><input type="number" min = 1 name="RollNo"></td>
</tr>
<tr><td>
<?php
$cser=mysqli_connect("localhost","root","","test") or die("connection failed:".mysqli_error());
$result = mysqli_query($cser,"SELECT pname FROM crud2") or die(mysql_error());
if (mysqli_num_rows($result)!=0)
{
echo 'Subject Name : </td><td><select name="pname">
<option value=" " selected="selected">Choose one</option>';
while($drop_2 = mysqli_fetch_array( $result ))
{
echo '<option value="'.$drop_2['pname'].'">'.$drop_2['pname'].'</option>';
}
echo '</select>';
}
?>
</td>
</tr>
<tr>
<td>Name</td>
<td><input type="text" pattern="[a-zA-Z][a-zA-Z ]{2,}" name="Name"></td>
</tr>
<tr>
<td>ObtainedMarks</td>
<td><input type="number" min = 1 name="ObtainedMarks"></td>
</tr>
<tr>
<td></td>
<td><input type="submit" name="Submit" value="Enter"></td>
</tr>
</table>
</form>
Change the PHP database name, column name.
This is form code. Search form code inside the insert code and replace complete form code to this.
