I have a question about displaying properties of an image
The situation is this :
I have a folder called images, where users can upload pics.
when the pic gets uploaded, the id also gets stored into a MySQL
database
when a certain page is called it retrieves the correct image from the
folder by connecting the ImageID from the database to the id in the
folder
So far so good, this works fine.
but when I retrieve the image from the folder I also need the width and
the height from the image, and that's the part I do not seem to get
right
this is the code I tried :
( Photo is the DataBase entry )
<dtml-call "REQUEST.set('photo',Photo)">
<dtml-with expr="inbox.photos.objectValues()">
<dtml-call "REQUEST.set('id',id)">
<dtml-call "REQUEST.set('width',width)">
<dtml-call "REQUEST.set('height',height)">
<dtml-if "photo == id"> <dtml-var id> <dtml-var width> <dtml-var
height> <dtml-else> No Pic </dtml-if>
</dtml-with>
I hope someone can help me out with this
Thanx in advance,
Menno
