Howdy,

I'd like to pull the EXIF information on my single photo pages into a PHP variable. All I need is the Model string to compare against an ifelse statement.

Thoughts?

Frankly, at this point my preference would be to use something like this PHP code block in the photo.tpl:

{php}
$theimageurl = '____ need help with this _____';
$exif_model = exif_read_data('$theimageurl', 'IFD0', 0);
$emodel = $exif_model['Model'];
{/php}

But I need to be able to place this code snippet into the variable to give me the image URL:

{g->url arg1="view=core.DownloadItem" arg2="itemId=`$theme.sourceImage.id`"}

Any help?

enable debugging in config.php to see the smarty variables that are available in each template.

$this->_reg_objects['g'][0]->url(array('arg1' => "view=core.DownloadItem",'arg2' => "itemId=".($this->_tpl_vars['theme']['sourceImage']['id']), 'forceFullUrl' => true, 'htmlEntities' => false), $this)

Wow -- that's really outstanding code! Very accurate! Thank you!

{php}
$theimageurl = $this->_reg_objects['g'][0]->url(array('arg1' => "view=core.DownloadItem",'arg2' => "itemId=".($this->_tpl_vars['theme']['sourceImage']['id']), 'forceFullUrl' => true, 'htmlEntities' => false), $this);
$exif_model = exif_read_data($theimageurl, 'IFD0', 0);
$emodel = $exif_model['Model'];

//example
echo 'the camera model is a ' . $emodel;
{/php}

for what it's worth, you can see an example of how I ended up implementing it here
