I have also added the 35mm equivilent focal length so that I can compare between cameras... Enjoy 8)

// EXIF STUFF
if(extension_loaded(exif)) {
        $curr_image = "images/$image_name";

        $exposure = $exif['ExposureTime'];
        $exifhtml = $all_exif['COMPUTED'];
        $aperture = pullout($exifhtml['ApertureFNumber']);
        $capture_date = $exif['DateTimeOriginal'];
        $flash = $exif['Flash'];
        $lens = pullout($exif['LensModel']);
        $focal = pullout($exif['FocalLength']);
        $pos = strpos( $focal, "/" );
        if( $pos ) {
                list($e, $d) = sscanf($focal, "%d/%d");
                $focal = sprintf( "%d", intval($e/$d) );
        }
        $iso = pullout($exif['ISOSpeedRatings']);

Some of the lines in the post have been word wrapped by the board. Make sure that you join all of the lines that are not indented back to the previous line in your code. It is probably those lines with just the } on them that are causing the most problem since they should be commented out in the previous line... :wink:

The next thing you will want to do is add the new tags to your template.

<EXIF_35MM_FOCAL_LENGTH> // This only works with my SLR, not my Olympus, give it a try
<EXIF_ISO> // Should be supported by most cameras

Also, don't forget that I removed the extra text from most of the EXIF tags, so you will need to add that to the template if you want it. I didn't want text like "Aperature:" forced on me.

Hope this helps. Check out my website to see it in action. Reply to this if not, I am watching this topic now...

not sure what im doing wrong here everytime i edit it even when i make sure it should look the way you had it with out word warp - it still gives me a blank page... =\

Email your edited index.php to me at rob at prouse.org and I will take a look at it for you, fix it and send it back.

Blank pages is faulty PHP code - in this case because you copy/paste the code from an HTML page.

If you replace the empty spaces at each code line in the beginning with a TAB (4 empty spaces = 1 TAB), then you should be fine.

You need to do that in a word processor where you can see the hidden stuff like returns and spaces, you then will notice that they look different than standard text input.

Is there anyway to format the way the date/time turns out?

#9 03-10-2005, 08:33 AM

did you try the date-format-option in the admin panel ?

I think he means the EXIF_CAPTURE_DATE. The control panel will not change that, it is currently just read and displayed from the photo. To get the date formatted by the control panel, change the one line of code in my code above (or in the original index.php) to the following three lines (the first line remains the same and is just so you know where to put it.)

Code:

$capture_date = $exif['DateTimeOriginal'];
$capture_date = strtotime($image_datetime);
$capture_date = date($cfgrow['dateformat'],$capture_date);

Now the capture date will be formatted the same as the posted date. Note that this depends on your camera saving the date in a parsable format. Both my Olympus and Minolta do, so I expect it is ok.
