SQL PHP : How to select some column from sql database and display it in PHP/HTML generated table in descending order where condition is…
Question
I have a sql table res which contains some rows and column. For example
Sno RegNo Name sub1 sub2 sub3 total percent result color
1 1DU12CS100 s1 10 10 10 30 50 fail danger
2 1DU12CS101 s2 20 20 20 60 80 pass success
3 1DU12CS102 s3 20 25 30 75 90 pass success
4 1DU12ME055 se 10 15 20 45 55 fail danger
5 1DU12IS044 as 20 20 30 70 80 pass success
6 1DU13CS077 sd 10 20 30 60 70 pass success
7 1DU14CS111 df 15 15 15 45 55 fail danger
8 1DU13ME006 fd 20 30 0 50 55 fail danger
9 1DU11CV123 my 20 20 20 30 70 pass success
10 1DU12CS444 yr 30 20 30 80 95 pass success
When someone will enter 1DU12CS100 in form.html (GET Method), I want to display the result in php/html generated table order by total in descending order. The result should look like
Rank Name RegNo Total Percent Result
1 yr 1DU12CS444 80 95 pass
2 s3 1DU12CS102 75 90 pass
3 s2 1DU12CS101 60 80 pass
4 s1 1DU12CS100 30 50 fail
I want the table styled by bootstrap. If the result is pass then row should be green, if result is fail then row should be red...
1DU12CS100 should first get substr( res.RegNo, 1, 7 ) .... [ I think ]
The form.html code is
<!DOCTYPE html>
<head>
<link rel="stylesheet" href="http://maxcdn.bootstrapcdn.com/bootstrap/3.2.0/css/bootstrap.min.css">
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<script src="http://maxcdn.bootstrapcdn.com/bootstrap/3.2.0/js/bootstrap.min.js"></script>
</head>
<body>
<div class="container">
<div id="wrap">
<form action="rank.php" class="form-horizontal" method="get">
<fieldset>
<div class="form-group">
<label class="col-md-4 control-label" for="RegNo">Enter your Reg No :</label>
<div class="col-md-5">
<input id="RegNo" name="RegNo" value="" class="form-control input-md" required type="text">
</div>
</div>
<div class="form-group">
<label class="col-md-4 control-label" for="submit"></label>
<div class="col-md-4">
<button id="submit" type="submit" value="Submit" class="btn btn-success">Get Rank</button>
</div>
</div>
</fieldset>
</form>
</body>
</html>
What should be code for rank.php ?

Error checking and security aside, the basics are:
//get number from querystring
$regNo = $_GET['regNo'];
//get substring
$search = substring($regNo,0,7);
//create query
$sql = "SELECT * FROM `res` WHERE `RegNo` like '$search%' ORDER BY `Total` DESC";
Creating the html table is just a matter of looping the results and building the html.
