คือแบบนี้อ่ะครับ
Code (PHP)
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title> Input Data </title>
<link rel="stylesheet" href="home.css"/>
</head>
<body>
<header>
<h1> Airnet Intelligence Installation </h1>
</header>
<aside>
</aside>
<section>
<form action="compare.php" method="post">
<table border=0>
<tr> <td> Latitude </td> <td> <input id="lat" name="lat" type="text" /> </td> </tr>
<tr> <td> Longtitude </td> <td> <input id="long" name="long" type="text"/> </td> </tr>
<tr> <td> <li> Distance </td> <td> <input id="distance" name="distance" type="text" /> km </td> </tr>
</table>
<!-- <input type="hidden" name="number" value=""/> -->
<input class="submit" type="submit" value="submit"/>
</form>
</section>
</body>
</html>
โดยผมส่งค่าที่ได้ใส่ข้อมูลไป ที่หน้า compare
compare(PHP)

$dist = acos(sin($lat_rad1) * sin($lat_rad2) + cos($lat_rad1) * cos($lat_rad2) *cos($long_rad1 - $long_rad2));
$real_dist = $dist*$radius;
$i++;
/*
echo"<tr>";
echo"<td> $i </td>
<td> {$result['APname']} </td>
<td> $real_dist </td>
<td> $real_degree </td>";
echo"</tr>";
*/
}
//echo "</table>";
}
?>
ที่นี่ผมต้องการนำค่า $i , $result['APname'] $real_dist $real_degree พวกนี้อ่ะครับ ไปใช้อีกหน้านึง
ผมต้องใช้คำสั่งยังไงอ่ะครับ
ขอบคุณครับ
