You sent a photo to help me debug the missing IPTC Headline data from my MMWW plugin. Thank you for your help!

But, as far as I can see using both Adobe Bridge and the open source exiv2 tool (https://www.exiv2.org/) this photo contains no IPTC metadata.

I wonder if you have a different photo? Thanks again.

Hello, Pepe, thanks for the bug report. I wonder if you could send me a sample jpg file that shows the problem?
Thanks.

Version 1.0.4 supports a whole bunch of IPTC metadata. Please see the plugin’s description for that. Thanks for your request.

The IPTC Headline field comes in as {title} in MMWW 1.0.3
Creator shows up in {credit}
Description shows up {description}

I’m looking at adding other IPTC fields in a future release.

Hello, Pepe. Please excuse my slow response. I would be happy to add support for more IPTC fields.

I am sorry that I don’t have a copy of Apple Aperture. I wonder if you could provide a sample image or two so I can be sure to extract the correct information. I won’t use your images for any purpose other than testing.

A list of the fields you’d like extracted, or a pointer to the list, would also be helpful. Thanks!

This should be fixed in version 1.0.2, thanks to Kevin’s help with sample files. It turns out that some pdf files contain multiple stanzas of xmp metadata.

Kevin contacted me with a similar problem retrieving XMP metadata from his pdf files.

It turns out that some PDF files contain multiple XMP metadata stanzas. (Each metadata stanza is a well-formed chunk of XML.)

The first one is pretty much a stub; but later ones contain the useful metadata. That accounts for MMWW (my plugin)’s failure to read his metadata correctly. My version 1.0.2 corrects it.

Don’t hesitate to steal my opensource code if you want it. It doesn’t use the Zend framework; but it does use PHP’s xml handling.

All set.

1.0.1 resolves your issue. I’ve also added a few other EXIF parameters. If anybody knows a way to use the heading (direction) data from the iPhone’s GPS and compass feature, I’d love to hear about it.

Thanks for the feature request, Ben303.

I take it you’d like to be able to use the settings page to indicate that you’d like to create a category from an ID3 property value of your choice (such as genre or year), and then have uploaded audio files be automatically inserted into the category. Do I have that right?

Do you want the same sort of thing for tags?

It would be helpful if you could explain what you’re trying to do. Thanks again.

Hi, thanks for the feedback. MMWW does (at any rate it does on my photos) extract focal length. I will add ISO.

Would you send me a sample JPEG file of yours from which it is not retrieving focal length correctly? That way I can debug the focal length code if it’s wrong. [email protected]

There’s a relatively new plugin, developed by me, called MMWW, that read metadata from jpeg and some other file types beyond what wp_get_attachment_metadata does.

Please take a look. If it doesn’t meet your needs exactly, please let me know.

Esmi, the latest version of MMWW will set the WordPress attachment titles, alt, caption, and description from the embedded metadata in the photos, as you upload them.

You can upload them singly, or in a batch, from the Media Manager or the Insert Media popup in the post editor.

It doesn’t set XMP, IPTC, or EXIF, but it does read them from the files.

I hope this helps.

Version 0.9.3 takes care of this problem.

Les Bessant, I’m responding to your request for a code review. This code solves your problem fine. But I see two issues that should be addressed before it goes out for general use.

First, if it’s activated on a pre 3.5 installation it will put an extra title attribute into the image; it inserts the title attribute without first checking whether one is already present.

Second, if the post_title happens to contain markup characters your code will emit a malformed img tag.

Other than that, looks good.
