Metadata Exif Version 0.9.0 (currently a WIP) for PW 2.8.+ / 3.0+ This is a new attempt to add easy EXIF reading support to ProcessWire. It should be an easy and less error prone API task. Thats why the module internally uses lowercase key names for all EXIF keys and all of your requested key names. But you are not forced to use lowercase key names, you can use any mixed chars for it as you like. You will get back an array or object with keynames / properties named the same (casesensitive) way as you have passed them in with your request. API The module adds one hook to the Pageimage: getExif($options = null) Without any $options passed to the method, it returns all EXIF data in a RAW multidim array. Passing a simple list with requested key names as array to it returns an array with only the values of those requested keynames. If you want change the output from array to object, you can use the a boolean "toObject" set to true. Additionally to this and / or any other option, you need to put your requested keynames list to the option "keys". $rawArray = $image->getExif(); $options = array('Whitebalance', 'Flash', 'ISOSpeedRatings', 'FNumber', 'UserComment'); $array = $image->getExif($options); $options = array('toObject' => true, 'keys' => array('whitebalance', 'flash', 'isospeedratings', 'fnumber', 'usercomment')); $object = $image->getExif($options); Possible options are A working example $options = array( 'keys' => array('ISOSpeedRatings', 'FNumber', 'Flash') ); echo "<table><tr>"; foreach($options['keys'] as $key) echo "<th>{$key}</th>"; echo "</tr>"; foreach($page->images as $image) { $exif = $image->getExif($options); echo "<tr>"; foreach($exif as $value) echo "<td>$value</td>"; echo "</tr>"; } echo "</table>"; This will output something like: With the boolean option "unformatted" passed as true, the output would look like: For some keys, that only store something like integer values, what are not very meaningful to most of us, the module contain xyzFormatted methods. This way, it is easy to enhance and maintain the module in the future. Help wanted It would be nice if some of you test the module and report back if the intended API suites your needs. And you are very welcome to post suggestions for which keys you want to have a ...Formatted method. Thank you! https://github.com/horst-n/MetadataExif

Hi. Can I ask why this happens? When I upload a jpg, the meta keywords and description of the file loses the accents and spanish symbols of the words. Original image on the left, and the image generated by PW on resize on the right. This happens on resize. The uploaded file is ok. How can I control which meta keep in the photo? Thanks a lot (and sorry for my English)...

I have some functionality on an intranet site that uses Lazy Cron to query an external API and then update a bunch of pages based on the API response. A problem I've noticed is that this breaks our author / editor tracking – whenever a user triggers the Lazy Cron job, the page metadata for `$page->modified` and `$page->modifiedUser` is (naturally) updated, so it now looks like that user edited the page at that moment in time, even if the content of the page was edited months ago by someone else. It seems like the ideal solution here would be to somehow exempt certain fields (the ones that get updated by this external API) from triggering a timestamp update... Any ideas on how I'd go about hooking into that?
