These are my codes

1) When I want to update a person's details, I have to first choose the person.

<!doctype html>




<html class="no-js" lang="en">

<head>
<meta charset="utf-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1">
<title>Community Night Cycling 2014 Singapore</title>
<meta name="viewport" content="width=device-width,initial-scale=1,maximum-scale=1.0,user-scalable = no">

<meta name="author" content="" />

<link rel="stylesheet" href="style/framework.css" />
<link rel="stylesheet" href="style/site.css" />
<script src="js/modernizr-2.0.6.min.js" type="text/javascript"></script>
</head>
<body class="contact">

</header>

<form name="input" action="insert-update.php" method="POST">
$result = mysql_query("SELECT * FROM members ", $connection);
echo 'SELECT Name <select name="name">';
while($row=mysql_fetch_array($result))
{
echo "<option value='".$row['Name']."'>".$row['Name']."</option>";
}
echo "</select>";
?>
<input type="submit" value="Submit">
</form>

<script src="js/jquery.min.js" type="text/javascript"></script>
<script defer src="js/accessories-min.js" type="text/javascript"></script>
<script defer src="js/site.js" type="text/javascript"></script>

</body>
</html>

2)After I choose the person from the dropdown list and click on Submit from thee previous page, it redirects to this page. Here I am having problem to retrieve and display the data as well as the input types to update particulars. I feel tat the problem is coming from the while loop becoz I can only see the table border displaying field and value:

Solution 1

As far as I can see, these are my findings from your second code block:
1. action="process-update.html" is wrong, the action value must be a server side script that ends with php extension, not html.
2. You are still not careful on the quotes, value='".$row['Name']."' should be value='".$row['Name']."'" and other similar mistakes
3. why are there so many echo""?
4. why if ($fgender == "Male") echo"" else echo""? Did not make sense.
Btw, did my answer to your previous question help?

<form action="process-update.php" method="post">
                    <?php
        $selname = $_POST['name'];
        {
        $result = mysql_query("SELECT * FROM member WHERE Name = '".$selname."'", $connection);
        }
        echo "<table border='1'><tr><th>Field</th><th>Value</th></tr>";

        while($row = mysql_fetch_array($result))
        {
        echo "<tr><td> Name</td><td><input type='text' name='uName' value='" . $row['Name'] . "'></td></tr>";
        }
        echo "</table>";

        mysql_close($connection);

        ?>
        Update<input type='radio' name='fAction' value='Update' checked> <br/>
        Delete<input type='radio' name='fAction' value='Delete'> <br/>

            <button type="submit">Submit</button>
                    </form>
