Create Table first using PHPmyadmin of Student with four-column (rno,sname, branch, fees)
Create HTML View using viewrecord.php
<!DOCTYPE html>
<html>
<head>
<title></title>
<style type="text/css">
table
{
width:600px;
}
table th
{
background-color:yellow;
color:blue;

}
        table td

<body>
<h1>View Student Record</h1>
<hr>
<table border="1">
<tr><th>Rno</th><th>Sname</th><th>Branch</th><th>Fees</th></tr>
<?php
$conn= mysqli_connect('localhost','root','','php12batch');
$res = mysqli_query($conn,"select * from student");
while($x = mysqli_fetch_array($res))
{
  echo "<tr><td>".$x[0],'</td><td>' ,$x[1],'</td><td>',$x[2],'</td><td> ',$x[3],"</td><td><a href='editstudent.php?q=".$x[0]."'>Edit</a></td><td><a href='deletestudent.php?q=".$x[0]."'>Delete</a></td></tr>";
}
?>
</table>
Step2nd:-  Create EditStudent.php

<?php
$rno= $_REQUEST['q'];
$conn= mysqli_connect('localhost','root','','php12batch');
$res = mysqli_query($conn,"select * from student where rno=$rno");
if($x = mysqli_fetch_array($res))
{
?>
<h1>Are you sure you want to update record</h1>
<form action="" method="post">
<table>
<tr><td>RNO</td><td><input type="text" name="txtrno" value="<?php echo $x[0]; ?>"  readonly="true" /></td></tr>
<tr><td>NAME</td><td><input type="text" name="txtsname" value="<?php echo $x[1]; ?>"  /></td></tr>
<tr><td>BRANCH</td><td><input type="text" name="txtbranch" value="<?php echo $x[2]; ?>"  /></td></tr>
<tr><td>FEES</td><td><input type="text" name="txtfees" value="<?php echo $x[3]; ?>"  /></td></tr>
<tr><td></td><td><input type="submit" name="btnupdate" value="Update"/></td></tr>
</table>
</form>
<?php
}
if(isset($_REQUEST['btnupdate']))
{
$r = $_REQUEST['txtrno'];
$n = $_REQUEST['txtsname'];
$b = $_REQUEST['txtbranch'];
$f = $_REQUEST['txtfees'];
$res1= mysqli_query($conn,"update student set sname='$n',branch='$b',fees='$f' where rno='$r'");
if(mysqli_affected_rows($conn)>0)
{
echo "data updated successfully";
}
else
echo "problem in insertion";
}
?>
<a href="TableViewEditDeleteStudent.php">BACK to show record</a>

Create DeleteStudent.php

<?php
$rno= $_REQUEST['q'];
$conn= mysqli_connect('localhost','root','','php12batch');
$res = mysqli_query($conn,"select * from student where rno=$rno");
if($x = mysqli_fetch_array($res))
{
?>
<h1>Are you sure you want to delete record</h1>
<form action="" method="post">
<table>
<tr><td>RNO</td><td><input type="text" name="txtrno" value="<?php echo $x[0]; ?>"  readonly="true" /></td></tr>
<tr><td>NAME</td><td><input type="text" name="txtsname" value="<?php echo $x[1]; ?>"  /></td></tr>
<tr><td>BRANCH</td><td><input type="text" name="txtbranch" value="<?php echo $x[2]; ?>"  /></td></tr>
<tr><td>FEES</td><td><input type="text" name="txtfees" value="<?php echo $x[3]; ?>"  /></td></tr>
<tr><td></td><td><input type="submit" name="btndelete" value="Delete"/></td></tr>
</table>
</form>
<?php
}
if(isset($_REQUEST['btndelete']))
{
$r = $_REQUEST['txtrno'];
$n = $_REQUEST['txtsname'];
$b = $_REQUEST['txtbranch'];
$f = $_REQUEST['txtfees'];
$res1= mysqli_query($conn,"delete from student where rno='$r'");
if(mysqli_affected_rows($conn)>0)
{
echo "data deleted successfully";
}
else
echo "problem in deletion";

The uncontrolled input is similar to the traditional HTML form inputs. The DOM itself handles the form data.

Example of Uncontrolled Form Input:- import React from "react" ; export class Info extends React . Component {     constructor ( props )     {         super ( props );         this . fun = this . fun . bind ( this ); //event method binding         this . input = React . createRef ();...
