my problem of inserting data from radio-button has been resolved from above link but problems occurs when i increase the number of field from 5 to 18.
//here is my php code to process form
//various fields in post methods are name attribute of radio buttons
<?php
//Start session
session_start();
//Include database connection details
require_once('connection/config.php');
//Array to store validation errors
//$errmsg_arr = array();
//Validation error flag
//$errflag = false;
//Connect to mysql server
$link = mysql_connect(DB_HOST, DB_USER, DB_PASSWORD);
if(!$link) {
echo"Not Connected";
die('Failed to connect to server: ' . mysql_error());
}
//Select database
$db = mysql_select_db(DB_DATABASE);
if(!$db) {
echo "Not Selected";
die("Unable to select database");
}
//Function to sanitize values received from the form. Prevents SQL injection
function clean($str) {
$str = @trim($str);
if(get_magic_quotes_gpc()) {
$str = stripslashes($str);
}
return mysql_real_escape_string($str);
}
//Sanitize the POST values
$ans = clean($_POST['25rboption13']);
//If there are input validations, redirect back to the same form
/*if($errflag) {
$_SESSION['ERRMSG_ARR'] = $errmsg_arr;
session_write_close();
header("location: .php");
exit();
}
*/
//Check whether the query was successful or not
if(isset($_POST['submit'])){
$ans1=isset($_POST['25rboption13']);
$ans2=isset($_POST['129rboption13']);
$ans3=isset($_POST['150rboption13']);
$ans4=isset($_POST['151rboption13']);
$ans5=isset($_POST['152rboption13']);
/* $ans6=isset($_POST['153rboption13']);
$ans7=isset($_POST['154rboption13']);
$ans8=isset($_POST['592rboption13']);
$ans9=isset($_POST['593rboption13']);
$ans10=isset($_POST['594rboption13']);
$ans11=isset($_POST['595rboption13']);
$ans12=isset($_POST['596rboption13']);
$ans13=isset($_POST['1169rboption13']);
*/
if($ans!=""){
//Create query
$qry="INSERT INTO diseases (q1,q2,q3,q4,q5) values(' ".$_POST['25rboption13']." ',' ".$_POST['129rboption13']." ',' ".$_POST['150rboption13']." ',' ".$_POST['151rboption13']." ',' ".$_POST['152rboption13']." ')";
$result=mysql_query($qry);
echo "data inserted";
} //Successful
