Image upload script met voorwaarden
Ben een NooB met PHP.
Heb overal gezocht, ook hier, maar niet gevonden.
Wat ik zoek:
Een uploadscript (via ftp, explorer look a like) voor images met de volgende voorwaarden:
1) Images mogen niet groter dan 500 kB zijn
2) Maximaal te uploaden images is 1
3) Webruimte gebruik (per map) is dus ongeveer 500 kB (controle hierop ivm onjuist gebruik webruimte)
4) De image die geupload wordt gaat image1.jpg heten (of png/gif)
5) Indien er al een image1 bestaat in de map wordt deze overschreven
6) Mogelijkheid om de image te tonen (mag een apparte html-pagina zijn)
7) Image mag extentie jpg, png of gif hebben
8) Indien de map geen image bevat dient er een standaard plaatje, b.v. leeg.png, getoond te worden
Uitleg waarom deze vraag:
Ik heb een website waar leden kunnen inloggen (een gekochte applet die dit regeld) op een eigen pagina. Nu wil ik dat zij op deze pagina 1 plaatje met eventueel een tekst kunnen plaatsen (en het plaatje ook kunnen wijzigen).
Zoals al gezegd heb ik overal al rond gekeken maar (nog) niet kunnen vinden wat hieraan voldoet.
Hoop dat jullie mij kunnen helpen.
Groet en alvast dank.
Dirk.

Link: http://www.coffeecup.com/password-wizard/help/applet-password-wizard-layout.225.html alleen ziet het er nu anders uit dan jaren terug.
Kan ik dit scriptje eens zelf op mijn website zetten en proberen?
Wanneer en waarom komt deze melding "Sorry, dit type accepteer ik niet!"?

Dit genereerd 3 plaatjes met de extentie png, gif of jpg en noemt deze test.
Hoe kan ik nu het laatst geuploadde plaatje tonen op mijn website (html-pagina) ?
Dirk.
Ook ik gebruik onderstaande script welke ook te vinden is via:
//bron: http://www.phpfreakz.com/library.php?sid=25136
Echter heb ik wel een vraagje want in onderstaande regels schrijft de maker set a rename prefix dit heb ik geprobeerd maar krijg ik niet voorelkaar.
Quote:
$m_cnfg['newname'] = ""; // file rename "" or "timestamp" or set a rename prefix
$m_cnfg['inputname'] = "bestanden"; // input file form array name
$m_cnfg['inputname'] = "bestanden"; // input file form array name
Wat ik wel is een bestand beginnen met de gebruikers_id dus als deze 123 is en hij zal uploaden het bestand 'muziek.jpg moet dit '123-muziek.jpg' worden.
Dan weet ik altijd wie welk bestand heeft geupload en krijg je eigenlijk ook nooit dubbele bestanden..
Kan iemand mij hiermee helpen..
thanx
Jan
