Basically I created a leapyear calculator, but to improve user experience i want it to display a message on the webpage confirming whether or not the year entered is a leapyear without changing the webpage.
<html lang="en">
<head>
<meta http-equiv="content-type" content="text/html; charset=utf-8" />
<meta name="keywords" content="Web,programming" />
<title>Leap year form</title>
</head>
<body>
<?php
$year = isset($_GET["leapyear"]);
function is_leapyear($year){
if(is_numeric($year)){
if($year%4 ==0)
if($year%100 ==0)
if($year%400 ==0){
return true;
}
return false;
}
}
if (isset($_GET["confirm"])){
if ($year == true){
echo'<span style="color:#008631;">';
echo"$year is a leap year</span>";
}else{
echo'<span style="color:#FF0000;">';
echo "$year is not a leap year</span>";
}
}
?>
<h1>Lab 03 Task 2 - Leap Year</h1>
<form action = "leapyear_selfcall.php" method = "get" >
<label for="leapyear">Enter a year</label>
<input type="text" name="leapyear"/>
<p>
<input type="submit" name="confirm" value="Check For Leap Year"/>
</p>
</form>
</body>
</html>
The result I get is "1 is a leapyear" and not the entered input. Where did I make the mistake?
I think you have made a mistake in the year checking condition. Please see below updated code:
$year = isset($_GET["leapyear"]) ? $_GET["leapyear"] : 0 ;
Added above line to set year value in $year if set otherwise zero
if (isset($_GET["confirm"])){
if (is_leapyear($year)){
echo'<span style="color:#008631;">';
echo"$year is a leap year</span>";
}
else
{
echo'<span style="color:#FF0000;">';
echo "$year is not a leap year</span>";
}
}
