Please bear with me as I am very new to php and html.
I have a form with several drop down menus, the one at the top shows a list that when an item is selected fills in the form below including the other drop downs. So when an item is selected the form gets info from a mysql database and then fills in the form. At this point the user can further modify the form and re-submit it to update the database. This means that the drop downs in the form not only need to display the relavent options from the database to reflect the existing choice but also when clicked on show a list to allow the user the change the selection from the list.
This means that the dropdown needs to: show the words 'select item' when the form is first loaded and the form is empty show the current selection when the defined by a selection in the top drodown show all the available items when the list is dropped down Curently my drop down does only this: shows the nothing when the form is first loaded and the form is empty shows the current selection when defined by a selection in the top drodown show all the available items when the list is dropped down plus the one that was there before it was clicked on, therefore doubing the option up showing the same option twice
The form is here if you would like to see it in action: http://www.spencercarpenter.co.uk/portfolioAppFiles/simpleForm.php
And a snippet of code from one of th drop downs is here:
Code: <select name="img01" onChange="updateImg(this, 'thumbImg01')"> <option value=-"-1" ><?php echo $row_chosen_pItem['img01']; ?></option> <?php buildFileList5('uploaded');?> </select> the code inside the 'buildFileList5' looks like this:
Code: <?php function buildFileList5($theFolder) { // Execute code if the folder can be opened, or fail silently if ($contents = @ scandir($theFolder)) { // initialize an array for matching files $found = array(); // Create an array of file types $fileTypes = array('jpg','jpeg','gif','png'); // Traverse the folder, and add filename to $found array if type matches $found = array(); foreach ($contents as $item) { $fileInfo = pathinfo($item); if (array_key_exists('extension', $fileInfo) && in_array($fileInfo['extension'],$fileTypes)) { $found[] = $item; } } // Check the $found array is not empty if ($found) { // Sort in natural, case-insensitive order, and populate menu natcasesort($found); $selectedImage = ""; //default image foreach ($found as $filename) { if(!empty($_POST['img01']) && $_POST['img01'] == $filename) { $sel = "SELECTED"; $selectedImage = $filename; } echo "<option value='$filename' $sel>$filename</option>n"; } } } } ?>
I hope that is enough info to explain it.
If anyone could tell how to get the dropdown working properly I would be very gratefull.
