I am developing my first simple website using PHP. Now, I am working in the admin page and I want to let him adding, deleting users and editing the personal information of the existed users. I did the adding and deleting. Now, I want to develop editing users. First of all, I want him to choose the user from drop list, then fetch the user information automatically after choosing him from the drop list, and after that editing his information. So how can I do that?

My code:

<?php
ob_start();
$host="localhost"; // Host name
$username="root"; // Mysql username
$password="13524"; // Mysql password
$db_name="sharingi_db"; // Database name

// Connect to server and select databse.
mysql_connect("$host", "$username", "$password")or die("cannot connect");
mysql_select_db("$db_name")or die("cannot select DB");

?>

<html xmlns="http://www.w3.org/1999/xhtml">

<head>
<script language="javascript">
    function reload(form){
        var val=form.username.options[form.username.options.selectedIndex].value;
        self.location='editUser2.php?username=' + val ;
    }
    </script>
</head>
<body>

<div id="content_main" class="admin_student_height">

<!-- Here starts the first form -->
<form method="get">
        <h3>Choose A User</h3> <br />
        select name="username" onchange="reload(this.form)">

                <option> 
        <?php
           if(isset($_GET['username']))
           echo "{$_GET['username']}"; 
           else echo "Select one";
        ?> 
            </option>

                <?php
                   if(isset($_GET['username'])){
           $exceptcc = $_GET['username'];
           $sql = "SELECT username FROM user WHERE user.username NOT IN
                                 ('$exceptcc')";
                    }
           else 
           $sql = "SELECT username FROM user";
           $result = mysql_query($sql);
           while($row = mysql_fetch_array($result)){
           echo "<option value={$row['username']}>{$row['username']}</option>";
                                }
        ?>
        </select><br /><br />

        <h3>User Information</h3> <br />
        <?php 
           $thecc = $_GET['username'];
           $sql = "SELECT Firstname FROM user WHERE Username=$thecc";
           $result = mysql_query($sql);
           while($row = mysql_fetch_array($result)){
           echo "{$row['Firstname']}>{$row['Firstname']}}";
                                }
        ?>
        <br /><br />
        </form> <br />

    I’ve been working on making a web-based ticketing system and ran into this same situation.
    I solved the problem like this:

    1. When the page is loaded, determine if they have admin rights or throw them off the page.
    2. Do an SQL Query to get the List of users, to either display in a list or in a drop down box.
    3. Once the User to edit has been selected, Do another Query and load each item into a field;
      what I did was use the same form for adding new users but have php build the form and insert the current values for that user into the fields.
    4. When this form is submitted, (and submitter verifed) I have the php script look at the submitted username and use that for the where clause in the sql update statement

    If you want me to post up an example of what I did I can do that.
