Connect to the database
Simple / basic insertion operation
Insertion of Records into Database using Forms: PHP & MySQL (important)
SELECT / LIST Records From Database Table: PHP & MySQL

SELECTING and Displaying Data
index.php
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 | < ?php
include_once('db.php');
if(isset($_POST['name']))
{
$name = $_POST['name'];
if(mysql_query("INSERT INTO apple VALUES('','$name')"))
echo "Successful Insertion!";
else
echo "Please try again";
}
$res = mysql_query("SELECT * FROM apple");
?>
<html>
<head>
<style type="text/css">
li { list-style-type: none; display: inline; padding: 10px; text-align: center;}
// li:hover { background-color: yellow; }
</style>
</head>
<body>
<form action="." method="POST">
Name: <input type="text" name="name"/><br />
<input type="submit" value=" Enter "/>
</form>
<h1>List of companies ..</h1>
<ul>
< ?php
while( $row = mysql_fetch_array($res) )
echo "<li>$row[id]. <li>$row[name]</li>
<li><a href='edit.php?edit=$row[id]'>edit</a></li>
<li><a href='delete.php?del=$row[id]'>delete</a></li><br />";
?>
</ul>
</body>
</html> |
Some CSS styling for simple / basic presentation: CSS Hover Over Effect
We have added delete link beside each record.
Deleting Records From Database Table
1 2 3 4 5 6 7 8 9 10 11 | < ?php
include_once('db.php');
if( isset($_GET['del']) )
{
$id = $_GET['del'];
$sql= "DELETE FROM apple WHERE id='$id'";
$res= mysql_query($sql) or die("Failed".mysql_error());
echo "<meta http-equiv='refresh' content='0;url=index.php'>";
}
?> |
Here we receive the value of id, passed from index.php and assign it to a local variable called $id.
Then using simple DELETE query, we delete the records associated with the id.
