How to use exif_read_data and ALL_IPTC
-
Hello David!
Thank You for providing this fascinating plugin!
It’s great to be able to browse the media by different taxonomies.
I guess your plugin can do much more but have some difficulties in finding out how.
The support-forum (and you) seem to be very active, but I found no sensible way to search inside the forum. I already read a lot of topics but I can’t read all of them to find what I’m searching for. So I now write to you directly.
Please let me frist introduce my circumstances:
I’m new to WordPress and don’t know anything about php and the WP Shortcode API.
My Goal is to create a new website for the business of my wife. She’s specialized in restoration and preservation of mural art, sculpture painting and so on. She will need to use a lot of foto-material on her pages that will need to be categorized. For SEO-Optimization and for better organization I would like to put alt-text, caption, title, description, copyright, keywords and so on into the Metadata of the files. To do this, I found a perfect tool to administrate the metadata that also works as a catalog:
https://sourceforge.net/projects/fastphototagger/
it uses the meta-tags of the ExifTool written by Phil Harvey.
Now I would like to “import” these metadata to standard WP-Fields and (if no standard field fits) custom fields. I read the appropriate sections of the documentation and tried to configure the IPTC/EXIF Tab (see sreenshot). But I cannot see any result. I guessed, that the tag-names and tag-ids produced by fastphototagger and ExifTool differ from the ones used by MLA-plugin and tried to get a list of all meta-tags found by MLA-plugin as described in this post.
But I don’t get any output . I had expected something like the exif_read_data Array Dump in the post above. I guess that I used the wrong syntax (tried [mla_gallery +exif:ALL_EXIF+] and [mla_gallery +iptc:ALL_IPTC+]).
Can you provide me with a shortcut, that gives away all the meta-data of an image file?
That would be great!

Thanks for your kind words about MLA and for the detailed description of your application and questions. I share your frustration about searching within the forum, as have several others over the months/years.
Here is a more recent support topic that might help, and it contains links to other topics along similar lines:
Lightroom IPTC Description Field > WordPress Description Field
The shortcode syntax can be a bit tricky if you’re new to WordPress, and the examples you’ve included are reasonable attempts; you’re on the right track. My favorite approach for a quick look at the data uses
[mla_gallery]and itsmla_captionparameter:[mla_gallery columns=1 post_parent=all posts_per_page=10 mla_caption="{+iptc:ALL_IPTC+}"]In this example,
columns=1puts each gallery item on its own line,post_parent=allselects all of the image items in your Media Library,posts_per_page=10limits the gallery display to ten items andmla_caption="{+iptc:ALL_IPTC+}"displays the IPTC metadata under the image thumbnail. If you want to see everything at once, try something like:[mla_gallery columns=1 post_parent=all posts_per_page=10 mla_caption="{+iptc:ALL_IPTC+}<br>{+exif:ALL_EXIF+}<br>{+xmp:ALL_XMP+}"]You will discover that EXIF and XMP data has a lot of arrays, which appear as placeholders in the above results. You can explore array values individually by coding something like
{+exif:COMPUTED,export+}to expand all levels within the array or{+exif:CAMERA,unpack+}to expand one level within the array. You can go deeper in the array hierarchy with compound names, e.g.,{+exif:CAMERA.ShutterSpeed+}or{+exif:CAMERA.LensSpecification,unpack+}. You can find additional examples and discussion in the “Field-level Substitution Parameters” section of the Settings/Media Library Assistant Documentation tab. You can also look through the “MLA Gallery Examples” section of the Documentation for other[mla_gallery]parameters and applications.I hope the above will help you make progress in accessing the metadata in your images. If you can post a link to one or more example images I can give you a more specific idea of what’s in them. I will leave this topic unresolved for now. Thanks for your interest I the plugin.
Hi David,
Thanks for your quick response!
For testing I have put only 2 pictures in my Library wich have some custom EXIF/IPTC Data.

Here is what I get as result:
result post 1
result post 2
Unfortunatly the result is more or less empty. What went wrong?
In the OpenOffice-textfiles
FPT-ExifTool-MetaData.odt
and
WP-Metadata.odt
I have marked the tags I have individually customized for the file P1230116.JPG
I would like to automatically fill the appropriate WP-standard fields with the contents of meta data tags like in the table meta tags.ods.
If possible, I’d like to fill the WP-Standard-Field “Description” with the content of multiple meta-tag-contents (i.e. title&caption&alt-text&Keywords&Categories©right).
I would be very thankful, if you could get me startet on this project!Thank you for our update with the links to and details of your two sample images. I uploaded your images to my test site and I am able to access the IPTC, EXIF and XMP metadata without any problems. The images have many IPTC and EXIF values and their content is consistent with the “fastphototagger/ExifTool” results you posted. The only data not available are the “MakerNotes:Panasonic” values, which are not parsed out by the PHP
exif_read_data()function that MLA uses.I cannot explain why your
[mla_gallery]shortcodes in “result post 1” and “result post 2” are returning empty arrays; I cannot recreate this problem on my test system. Have you tried accessing some of the individual values, for example:[mla_gallery columns=1 post_parent=all posts_per_page=10 mla_caption="ObjectName: {+iptc:2#005+}<br>Headline: {+iptc:2#105+}<br>ByLine: {+iptc:2#080+}<br>Keywords: {+iptc:2#025+}"]Can you confirm what operating system, version of WordPress and especially what version of PHP you are using?
Regarding the IPTC/EXIF mapping rules you posted in the
Bildschirmfoto 2016-02-22 um 20.59.46.pngscreenshot:- I would not advise mapping the Name/Slug value unless you have a specific reason to do so. This is an internal field and WordPress will modify the value to make it unique.
- The IPTC
2#015 categoryfield is defined in the IPTC standard as “Max 3 characters of the subject of the objectdata, DEPRECATED”. The values in your images are, strictly speaking, invalid. - Mapping values into the Categories/Kategorien and Tags/Schlagworte taxonomies can cause a few issues if you use the same terms for posts/pages and attachments. Most MLA users prefer to use the Att. Catelories and Att. Tags taxonomies to organize attachments.
Overall, the rules you have defined look fine and should work.
In your second post you wrote “In the OpenOffice-textfiles FPT-ExifTool-MetaData.odt and WP-Metadata.odt“, but I do not see a link to the actual documents.
In your
table meta tags.odstable you wrote “If possible: change real filename to IPTC ObjectName on upload“. MLA does not provide any direct functions to alter the file name of uploaded items, and I do not recommend doing so. If you must rename your files, there are some hooks MLA provides that you can use. See the “MLA Custom Field and IPTC/EXIF Mapping Actions and Filters (Hooks)” section of the Settings/Media Library Assistant Documentation tab and look for themla_upload_prefilterandmla_upload_filterhooks.You wrote “If possible, I’d like to fill the WP-Standard-Field “Description” with the content of multiple meta-tag-contents (i.e. title&caption&alt-text&Keywords&Categories©right).” If we can solve your metadata access issues you can use a Content Template like this to do that:
template:[+title+], [+caption+], [+alt_text+], [+terms:attachment_tag+], [+terms:attachment_category+], [+iptc:2#116+] or template:[+iptc:2#105+], [+iptc:2#120+], [+iptc:2#025+], [+iptc:2#020+], [+iptc:2#116+]As I said, I do not yet know why you are having trouble accessing the metadata in the test images. Any additional information you can supply about your site configuration would be helpful. Thanks for your understanding and your patience.
Hello David,
WOW! You are really an active and thorough guy. Thank you for taking so much time on my problems!
I will need some time to work through your tipps and right now I am not on my test-system, so I can’t provide you with informations to my system an configuration.
For now only quickly the missing links to the files mentioned in my recent post:
FPT-ExifTool-MetaData.odt
WP-Metadata.odtThanks for your update. Both of the links you posted go to
WP-Metadata.odt. If you have a separate link forFPT-ExifTool-MetaData.odt, let me know.I look forward to more information in response to my suggestions and questions.
Hi David,
thank you for the hint!
here’s the corrected link:
FPT-ExifTool-MetaData.odtMeanwhile I looked up your profile an the plugin hompage at fair trade judaica. I appreciate your work there very much! My wife and me support the fair trade idea by choosing fair trade products as far as possible. In 2011 we had a short (10 Days) round trip through Isreal and Palestine, so we espacially like the approach to solve the middle east conflict by “opening real economic oppurtunities”. That’s great work, hold on!

Thanks for your updates and for listing the plugins you are using on the site.
I regret that the “Easy Watermark” plugin is stripping all of the IPTC/EXIF/XMP metadata from the images when it adds the watermark. I get the same empty arrays you reported when I test with watermarked images. There is some EXIF data available, but none of the values you are interested in are retained.
You will have to restore the original images to get the metadata back. If you must watermark the images you can disable the “Auto Watermark” feature and watermark them manually after the upload and MLA mapping processes are complete. You can also define custom field mapping rules to retain the values you need before watermarking the images.
Let me know what else I can do to help you recover and retain the metadata you need.
Thank You for your quick analysis, great work!
I think, my problem is solved by your answers.
Next Weekend I will test MLA with Easy Watermark plugin deactivated and will try to contact the plugin author of Easy Watermark. I will ask him, if it is possible to launch a version, that leaves the MeaData unchanged. I will post his reply in this topic. So maybe you wait until then before closing this topic. If I have further question on MLA, I will post them in a new topic, OK?Thanks for your update; good luck with your further testing.
If the Easy Watermark author cannot produce a version that retains metadata, I have developed a small custom plugin you can add to your system to do the job. The custom plugin uses the hooks MLA provides to save the original metadata and then put it back into the file after the watermark processing is done.
I will leave this topic unresolved until I hear back from you. Thanks for your ongoing help with this issue.
I did some testing now and I can confirm, that when Easy Watermark plugin is deactivated or set to not applying watermarks on upload, MLA works without problems. All of the MetaData are there and get mapped to the WP-fields correctly. Even if I watermark the images after the update and MLA field mapping progress is done, the WP fields for the images are left untouched. So your tipp does half of the job already.
BUT: Easy Watermark produces new watermarked images in different sizes (small, large, thump, etc.) for displaying the images in different post types. In theses watermarked images (all sizes) almost all of the MetaData (EXIF, IPTC and XMP) -at least all of my individual data- are stripped from the files meta whereas the WP-fields still show the correct values. If a visitor copies or downloads a watermarked image file, he will get a file without copyright notice (except watermark) and further individual metadata like keywords, categories etc., wich is a great pity for me.
I trust your additional custom plugin will work fine with the fullsize original image, but will it work with all the other sizes Easy Watermark produces?
I started a new topic in the Easy Watermark support forum to find out, if Wojtec (the plugin author of Easy Watermark) can help.Thanks for your update and for posting your topic in the Easy Watermark forum. I have added some comments there:
Watermarking deletes EXIF, IPTC and XMP MetaData
It should be possible to extend the
mla-metadata-mapping-hooks-example.php.txtexample plugin to restore metadata in post-upload watermarking and it may be possible to add metadata to the intermediate sizes; I would have to do some research to be sure.I will wait and see what response your Easy Watermark support topic generates. Thanks for taking it up with them.
It has been a month since the last post in this topic. I assume you have found a solution to the metadata issues caused by the Easy Watermark plugin.
I am marking this topic resolved, but please update it if you have any problems or further questions regarding the topic.
Hi David, I just load MLA plugin, it is absolutley awesome, abut I don’t understand, how to configure them. It soooooooo complex like nuclear submarine ?? I need JUST USE DESCRIPTION FROM IMAGE TO WORDPRESS IMAGE DESCRIPTION. Automatically after uploading images. But, I tried some settings, it doesn’t work for. I am not able to set it correctly.
Thanks for your question. You can find my more detailed response in the other topic you posted to:
