I've got this upload form and would like to keep the selected option from the dropdown in the session in order to show the last selection after submitting, e.g. i choose the option 'colour' und after submitting colour is still selected in the dropdown. I echo $_SESSION['testname'] (just before the first radio button) and it gives me back "colour", but in the option-tag where i'd like to echo 'selected' if "colour" was the last selection, it returns nothing! what am i missing?
<?php
session_start();
if(isset($_POST['kategorie'])) {
$_SESSION['testname']=$_POST['kategorie']; }
?>
<?php
$con = mysqli_connect("localhost","Melvin","") or die ("could not connect to server: " . mysqli_connect_error($con));
mysqli_select_db($con, "galerie") or die ("Could not connect to database: " . mysqli_error($con));
if(isset($_POST['submit'])){
$name = $_FILES['file']['name'];
$sub_name = substr($name, 0, -4);
$img_ext = ".jpg";
$tmp_name = $_FILES['file']['tmp_name'];
$location = '_images/_galerie/';
$target = '_images/_galerie/' .$name;
if(move_uploaded_file($tmp_name,$location.$name)){
echo "file uploaded";
$nam = $_POST['nam'];
$kategorie = $_POST['kategorie'];
$size = $_POST['size'];
if ($size == 'thumb') {
// add "thumb" between filename and extension
$extension_pos = strrpos($target, '.'); // find position of the last dot, so where the extension starts
$thumb = substr($target, 0, $extension_pos) . '_thumb' . substr($target, $extension_pos);
$query = mysqli_query($con , "INSERT INTO images(img_name,img_title,img_cat,img_size)VALUES('".$thumb."','$nam','$kategorie','$size')");
} else {
$query = mysqli_query($con , "INSERT INTO images(img_name,img_title,img_cat,img_size)VALUES('".$target."','$nam','$kategorie','$size')");
}
function renameImg() {
$name = $_FILES['file']['name'];
$target = '_images/_galerie/' .$name;
$extension_pos = strrpos($target, '.');
$thumb = substr($target, 0, $extension_pos) . '_thumb' . substr($target, $extension_pos);
rename($target, $thumb);
//echo $name . " replaced with " . $thumb;
};
renameImg();

>black and white. You could try and add a space between the end php tag and the end option >.<option value="colour" <?php if(isset($_SESSION['kategorie']) == "colour") { echo selected';} ?> >. If I remember correct, I had a similar issue with radiobuttons<option value="colour" <?php if("colour" == "colour") { echo ' selected';} ?> >Colour</option>not sure that actually works, but what I mean is not using the session and hard coding it
