when i select an item in search.php and try to update the selected record to update.php, dropdown item cant select the right value of that particular record that i want to update.

my Db,
deptcode varchar(50) PK

crscode varchar(50) PK
crsname varchar(50)
duration varchar(50
_deptcode varchar(50) FK

What I have tried:

    //get and pass value from 'searchForm.php'
    $id = ''; 
    if(isset( $_GET['id'])) {
        $id = $_GET['id']; 

    //retrieve  dbrecord to the form    
        //include db connection
        include "../php/dbconfig.php";
        // Prepare, bind and execute
        $sql = "SELECT crscode,crsname,duration,_deptcode FROM tblcourse WHERE crscode = ?";
        $stmt = $conn -> prepare ($sql);
        $stmt->bind_param("s", $id); 
        $stmt->bind_result($crscode, $crsname,$duration,$_deptcode);
        // Echo
        while ($stmt->fetch()) {
            echo "<pre>";
            echo "Deptcode: $crscode\n";
            echo "Deptname: $crsname\n";
            echo "Deptcode: $duration\n";
            echo "Deptname: $_deptcode\n";

        // Close
        $stmt -> close();
        $conn -> close();    

    }catch(Exception $e){
        //echo "<p>Caught exception: " . $e->getMessage() . "</p>";

    // Update Function
    function update(){
        $ID = $GLOBALS['id']; // Store the value of varialble $id
        // include db connection
        include "../php/dbconfig.php";
        // Prepare and bind
        $sql = "UPDATE tblcourse SET crsname = ?, duration = ?, _deptcode = ? WHERE crscode = ?";
        $stmt = $conn -> prepare($sql);
        $stmt -> bind_param("ssss",$crsname,$duration,$_deptcode,$ID);
        // Set parameters
        $crsname = trim($_POST['txtcrsname']);
        $duration = trim($_POST['txtduration']);
        $_deptcode = trim($_POST['cbodept']);
        // Execute
        if($stmt -> execute()){
            echo "  
                        window.alert('Record Updated!');

            echo "ERROR: Could not execute query:" . mysqli_error($conn);
        // close 
        $stmt -> close();
        $conn -> close();

    $mssg = "";
    include '../php/functions.php';
    //button update
        if(empty($_POST['txtcrscode']) || empty($_POST['txtcrsname']) || empty($_POST['txtduration']) || empty($_POST['cbodept'])){
            $GLOBALS['mssg'] = "Please fill up all fields!";
            update();   //calling update function

    //btn cancel
    if (isset($_POST['btncancel'])){
        echo " window.location='searchDept.php';  ";

hello !

when you submit your choice, you're querying '#.php" , you may prefer "update.php" as 'action' attribute

Where is the code for update.php, we cannot see what you are trying to do with what you supplied here as the code and your question/explanation does not make sense at all.

With the amount of questions you have asked to date you should know by now how to post a proper question with the proper tags etc, I have cleaned up the post for you, please do not post like that again.

As far as your code is concerned -
1. I do not see the html for your form and the select element
2. Your above code is incomplete, it will never run, you need to add error checks to see where your code is incorrect and then post the line of code and the error
3. Use the following code at the top of your page which will catch any and all errors -
ini_set('display_errors', 1);

4. Once you see the errors, post them here and we can then assist.
