filemtime or getlastmod

Hello, I would like to create a dynamic mulitple-choise - Form, in which the filenames, included in a subdirectory (e.g. imgstand) are listed as the Option-vale "value" and the modification-date of the file is shown in the HTML-page as date for selection of the user. If a user choise one or more values form the form and press the "Submit-Button", the script "show.phtml" should show the selected pictures. This runs very well at this time. The only problem is, that my following script only shows one date (IMO: of the first value (.)), and not create the date of each file. My Developing-System is Winnt/Apache/PHP3x but the www.server is linux/PHP4.x of course ! The error is on both systems the same. Who can help ? Thank`s Here is my phtml-Page and the included script: ---------------------------------- <html> <head> <meta http-equiv="content-type" content="text/html;charset=iso-8859-1"> <title>sachstandseite</title> </head> <body> <table border="0" cellpadding="0" cellspacing="2" width="100%"> <tr> <td>Aktuelle Meldungen</td> <td>Bilder von fr&uuml;her</td> </tr> <tr> <td></td> <td> <FORM name="pictures" method=POST action="show.phtml"> <? $handle=opendir('imgstand'); // Name of the subdirectory, where the files are while ($dvzinhalt=readdir($handle)) { $datei[]= "$dvzinhalt"; } ?> <select name='selection[]' multiple size=<?printf(count($datei)) // for multipleselection-counter ?>> <? for ($i=0; $i<count($datei); $i++) { // "value" should be the filename for the array selection[] to show.phtml echo "<OPTION value=$datei[$i]>"; // get unix-timestamp form each file in subdirectory $unixdatum=getlastmod($datei[$i]); // change date for normal people $datum=date("j. F Y", $unixdatum); echo "$datum"; } ?> </select><input type='submit' name='OK'></td> </FORM> </tr></table> </body> </html> ------------------------------------------------------
