beste,

ik heb een leuk script gevonden voor mijn foto's te bewaren. hierbij kan ik ook mp4 laten afspelen.
echter bij de thumbs zit ik met een vaste afbeelding voor iedere mp4 (foliogallery/images/video.png) ik heb ondertussen al gevonden als ik dit verander naar ($mp4_thumb = $album.'/thumbs/'.$filename.'.jpg';) kan ik een gepersonaliseerde jpg weergeven van de mp4.


maar hoe kan ik dit programmeren indien er geen gepersonaliseerde jpg bestaat toch de vaste afbeelding wordt weergegeven?

waarschijnlijk met de echo functie maar ik heb echter zero kennis van php.

alvast bedankt voor de hulp.

Wouter smets op 20/02/2018 21:57:09:
maar hoe kan ik dit programmeren indien er geen gepersonaliseerde jpg bestaat toch de vaste afbeelding wordt weergegeven?

Waarschijnlijk wederom met file_exists() (een controle of een afbeelding bestaat), of liever gezegd, een uitbreiding van dit if-blok met een else-component voor wanneer dit niet het geval is. Maar alles in dat eerste codefragment heet zo'n beetje $thumb, dus ik weet niet precies wat waarvoor dient.

bedankt voor de reactie,

ondertussen zelf gevonden.

$mp4_thumb = 'foliogallery/images/video.png';

moet worden.

$mp4_thumb = file_exists($album .'/thumbs/'.$filename.'.jpg') ? $album .'/thumbs/'.$filename.'.jpg' : 'foliogallery/images/video.png';
