my exif data is far from correct, im assuming its my camera and i read up that pixelpunk hasnt fooled around with exif much...be good to be able to enter the data via cms as a fallback...next version next version but the whole php exif thing rocks and id like to get it workin

just wondering what i might need to look at to take a look at all this myself, never delt with exif and havent had a chance to look through the script...

thanks, blinks

Make a new php file, call it exif-info.php or whatever you like.

Code:

&lt;?php

$all_exif = exif_read_data(test.jpg,0,true);

print_r($all_exif);

?>

That file will take the test.jpg image and spit out all, I mean all information that's available for a pickup.

Try to see what variables that's in there.
What camera do you use?
What information does it get wrong?

thats a cool trick there...im new to the whole exif and php thing...i dont quite know how to apply it to the image though

i have a canon 20d...and everything is wrong on the image i tested...shutter speed and apature were pretty far off, it told me the flash fired and it didnt, and the focal length didnt display at all

im assuming each camera has a different profile, i believe the 20d uses an updated exif but im not sure...

From what I know it's rather chaotic with vendors more or less choosing their own field names to write exif info.

A quick search for canon exif doesn't make me happy

But I know someone here had a Canon 300D and it worked out alright.

I have very limited knowledge, I'm not sure how I should move on further. Best way would be to find a class that reads the exif info and incorporate that into the script.

ill work on it for a while tomorrow and im sure ill figure it out, i have a better understanding now, maybe a future advancement would be to have profiles for different camera ranges...

my exif research from today didnt have a lot of info on canon, much less my model...so im sure it will be trial and error, but info ont he correct classes for different company/model ranges is out there...

thanks

Code:

&lt;?php 
echo "test1.jpg:&lt;br />\n"; 
$exif = exif_read_data('test.JPG', 'IFD0'); 
echo $exif===false ? "No header data found.&lt;br />\n" : "Image contains headers&lt;br />\n"; 

$exif = exif_read_data('test.JPG', 0, true); 
echo "test2.jpg:&lt;br />\n"; 
foreach ($exif as $key => $section) { 
   foreach ($section as $name => $val) { 
       echo "$key.$name: $val&lt;br />\n"; 
   } 
} 
?>

works good too
