Dropdown list set put selected value from database

Question

I am trying to create a drop down menu that will select a value that is stored in the database. Right now the code creates a dropdown with the first option selected. I have read through several tutorials, and tried to apply them, but I cannot get this working. I hope someone can help.

<div class="form-group">
    <label>Up-to-Date</label>
    <select class="form-control" name="uptodate"/>
        <option value="Ja">Ja</option>
        <option value="Nee">Nee</option>
    </select>
</div>

Whole code :

 <?php error_reporting(E_ALL); ini_set('display_errors', 1); session_start(); include("../includes/connect.php"); if (isset($_SESSION['logged_in'])) { if(isset($_POST['btnSlaOp'])) { $id=$_POST['id']; $uitgeleend=$_POST['uitgeleend']; $nr=$_POST['nr']; $model=$_POST['model']; $serienummer=$_POST['serienummer']; $capaciteit=$_POST['capaciteit']; $uptodate=$_POST['uptodate']; $persoon=$_POST['persoon']; $datumuitgeleend=$_POST['datumuitgeleend']; $datumretour=$_POST['datumretour']; $opmerking=$_POST['opmerking']; $sql="UPDATE ipads SET uitgeleend='$uitgeleend', nr='$nr', model='$model', serienummer='$serienummer', capaciteit='$capaciteit', uptodate='$uptodate', persoon='$persoon', datumuitgeleend='$datumuitgeleend', datumretour='$datumretour', opmerking='$opmerking' WHERE id='$id'"; $result=$db->query($sql); header("location:overzicht-ipads.php"); } else if (isset($_POST['btnSlaOpInGs'])) { $id=$_POST['id']; $uitgeleend=$_POST['uitgeleend']; $nr=$_POST['nr']; $model=$_POST['model']; $serienummer=$_POST['serienummer']; $capaciteit=$_POST['capaciteit']; $uptodate=$_POST['uptodate']; $persoon=$_POST['persoon']; $datumuitgeleend=$_POST['datumuitgeleend']; $datumretour=$_POST['datumretour']; $opmerking=$_POST['opmerking']; $sql ="UPDATE ipads SET nr='$nr', model='$model', serienummer='$serienummer', capaciteit='$capaciteit', uptodate='$uptodate', persoon='$persoon', datumuitgeleend='$datumuitgeleend', datumretour='$datumretour', opmerking='$opmerking' WHERE id='$id'"; $sql .="INSERT INTO geschiedenis (SELECT * FROM ipads WHERE id='$id')"; $sql .="UPDATE ipads SET uitgeleend='Nee', persoon='', datumuitgeleend='', datumretour='', opmerking='' WHERE id='$id'"; $result=mysqli_multi_query($db, $sql); header("location:overzicht-ipads.php"); } if(isset($_GET['id'])) { $id=$_GET['id']; $sql="SELECT id, uitgeleend, nr, model, serienummer, capaciteit, uptodate, persoon, datumuitgeleend, datumretour, opmerking FROM ipads WHERE id='$id'"; $result=$db->query($sql); $rij=$result->fetch_assoc(); $uitgeleend=$rij['uitgeleend']; $nr=$rij['nr']; $model=$rij['model']; $serienummer=$rij['serienummer']; $capaciteit=$rij['capaciteit']; $uptodate=$rij['uptodate']; $persoon=$rij['persoon']; $datumuitgeleend=$rij['datumuitgeleend']; $datumretour=$rij['datumretour']; $opmerking=$rij['opmerking']; include("../includes/get_header_wn.php"); ?> <h1 class="page-title">Wijzigen</h1> <ul class="breadcrumb"> <li><a href="index.php">Home</a> </li> <li class="active">Leen iPad <?php echo $nr ?></li> </ul> </div> <form id="gegevensForm" class="col-xs-4" form method="POST" action="overzicht-ipads-edit.php"> <input type="hidden" name="id" value="<?php echo $id?>"> <div class="form-group"> <label>Uitgeleend</label> <input type="text" class="form-control" name="uitgeleend" value="<?php echo $uitgeleend ?>" /> </div> <div class="form-group"> <label>Nr</label> <input type="text" class="form-control" name="nr" value="<?php echo $nr ?>" /> </div> <div class="form-group"> <label>Model</label> <input type="text" class="form-control" name="model" value="<?php echo $model ?>" /> </div> <div class="form-group"> <label>Serienummer</label> <input type="text" class="form-control" name="serienummer" value="<?php echo $serienummer ?>" /> </div> <div class="form-group"> <label>Capaciteit</label> <input type="text" class="form-control" name="capaciteit" value="<?php echo $capaciteit ?>" /> </div> <div class="form-group"> <label>Up-to-Date</label> <select class="form-control" name="uptodate"/> <option value="Ja">Ja</option> <option value="Nee">Nee</option> </select> </div> <div class="form-group"> <label>Persoon</label> <input type="text" class="form-control" name="persoon" value="<?php echo $persoon ?>" /> </div> <div class="form-group"> <label>Datum uitgeleend</label> <input type="text" id="datepicker" class="form-control" name="datumuitgeleend" value="<?php echo $datumuitgeleend ?>" /> </div> <div class="form-group"> <label>Datum retour</label> <input type="text" id="datepicker1" class="form-control" name="datumretour" value="<?php echo $datumretour ?>" /> </div> <div class="form-group"> <label for="comment">Opmerking</label> <textarea class="form-control" rows="5" id="comment" name="opmerking" /><?php echo $opmerking ?></textarea> </div> <button class="btn btn-primary pull-right" name="btnSlaOp" input type="submit"><i class="fa fa-save"></i> Opslaan</button> <a href="overzicht-ipads.php"><input type="button" name="btnCancel" value="Annuleer" class="btn btn-primary pull-left"></a> <button class="btn btn-primary pull-middle" name="btnSlaOpInGs" type="submit"><i class="fa fa-save"></i> Opslaan & Archiveren</button> <?php include('../includes/get_footer.php'); ?> </form> <?php } } else { header("location:overzicht-ipads.php"); } ?>

Answer 1

php: if($selectedVal == "yourVal") echo "selected";

eg:

<div class="form-group">
    <label>Up-to-Date</label>
    <select class="form-control" name="uptodate"/>
        <option value="Ja" <?php if($selectedVal == "Ja") echo "selected";?>>Ja</option>
        <option value="Nee" <?php if($selectedVal == "Nee") echo "selected";?>>Nee</option>
    </select>
</div>

edit: in your case, replace $selectedVal with $uptodate
