I am using Zope 2.3a2, and MySQLDA 1.1.3, with one patch installed (it was
supposed to fix problems with autoincrement fields)
Everything is installed, with no apparent problems.
I would like to store images as BLOBs in a MySQL database (version 3.22)
I am able to store the images in the database, but somehow, along the way,
they become corrupted, and show up in the browser as a corrupted image.
I can, howover, recognize some of the features of the original image. The
top part is mostly intact, and the colours seem right.
The image is retreived from the database like this: method named "image",
with everything *on one line*.
<dtml-in hent_bilde>
<dtml-call "RESPONSE.setHeader('Content-Type', 'image/gif')">
<dtml-call "RESPONSE.setHeader('Content-Length', _.len(bildefil))">
<dtml-var bildefil>
</dtml-in>
With "hent-bilde" as follows:
select * from bilder
where
<dtml-sqltest id type=int>
The URL used is: "..../image?id=10"
The image is stored in the database as follows:
insert into bilder
(bildefil, kilde, kommentar, bildetype)
values (
<dtml-sqlvar "REQUEST['bildefil'].read()" type=string>,
<dtml-sqlvar kilde type=string>,
<dtml-sqlvar kommentar type=string>,
<dtml-sqlvar bildetype type=string>
);
Any ideas?
I feel like I am *so* close to making this work!
