When I delete it works fine. When I cancel also it works fine. But when I edit and click on save after edit I get the message "Undefined index: search in ". Data gets saved though. How do I fix this.
Code is :
<html>
<head>
</head>
<body>
<?php
$page='search.php';
mysql_connect("localhost","root","") or die (mysql_error());
mysql_select_db("list") or die (mysql_error());
if(empty($_POST) === false)
{
if ($_POST['search'] == 'search')
{
$data=$_POST['criteria'];
if (empty($data) === true)
{
echo 'Please enter some text!!<br/>';
}
else
{
$get=mysql_query("SELECT SRNO, fname, lname, phone, email, address, comments from names where fname='" . mysql_real_escape_string($data) . "'");
if (mysql_num_rows($get)==0)
{
echo 'There are no search results!!';
}
else
{
echo '<table border=0 cellspacing=25 cellpadding=1>';
echo'<tr><th>Sr. No</th><th>First Name</th><th>Last Name</th><th>Phone No</th><th>E-mail</th><th>Address</th><th>Comments!!</th><th>Modify</th><th>Delete!</th></tr>';

}

}
