    Hi, David!

    I’m getting better at finding the solutions, but this one continues to stump me. I’m trying to do the EXIF field mapping.

    The metadata for the image showing on the WP edit media page is:

    ‘image_meta’ =>
    array (
    ‘aperture’ => ‘0’,
    ‘credit’ => ‘Arthur Smith’,
    ‘camera’ => ”,
    ‘caption’ => ‘This is the Title’,
    ‘created_timestamp’ => ‘0’,
    ‘copyright’ => ”,
    ‘focal_length’ => ‘0’,
    ‘iso’ => ‘0’,
    ‘shutter_speed’ => ‘0’,
    ‘title’ => ‘This is the Title’,
    ‘orientation’ => ‘0’,
    ‘keywords’ =>
    array (
    ),

    When I do ALL_EXIF, I get:

    ”array (
    ‘FileName’ => ‘ca_los_angeles_san_gabriel_cemetery.jpg’,
    ‘FileDateTime’ => 1488127956,
    ‘FileSize’ => 55986,
    ‘FileType’ => 2,
    ‘MimeType’ => ‘image/jpeg’,
    ‘SectionsFound’ => ‘ANY_TAG, IFD0, EXIF, WINXP’,
    ‘COMPUTED’ => ‘(ARRAY)’,
    ‘ImageDescription’ => ‘This is the Title’,
    ‘Artist’ => ‘Arthur Smith’,
    ‘Exif_IFD_Pointer’ => 2136,
    ‘Title’ => ‘This is the Title’,
    ‘Comments’ => ‘T’ . “\0” . ‘h’ . “\0” . ‘e’ . “\0” . ‘s’ . “\0” . ‘e’ . “\0” . ‘ ‘ . “\0” . ‘a’ . “\0” . ‘r’ . “\0” . ‘e’ . “\0” . ‘ ‘ . “\0” . ‘c’ . “\0” . ‘o’ . “\0” . ‘m’ . “\0” . ‘m’ . “\0” . ‘e’ . “\0” . ‘n’ . “\0” . ‘t’ . “\0” . ‘s’ . “\0” . ‘ ‘ . “\0” . ‘f’ . “\0” . ‘o’ . “\0” . ‘r’ . “\0” . ‘ ‘ . “\0” . ‘t’ . “\0” . ‘h’ . “\0” . ‘i’ . “\0” . ‘s’ . “\0” . ‘ ‘ . “\0” . ‘i’ . “\0” . ‘m’ . “\0” . ‘a’ . “\0” . ‘g’ . “\0” . ‘e’ . “\0” . ‘.’ . “\0″ . ” . “\0″ . ” . “\0″ . ”,
    ‘Author’ => ‘A’ . “\0” . ‘r’ . “\0” . ‘t’ . “\0” . ‘h’ . “\0” . ‘u’ . “\0” . ‘r’ . “\0” . ‘ ‘ . “\0” . ‘S’ . “\0” . ‘m’ . “\0” . ‘i’ . “\0” . ‘t’ . “\0” . ‘h’ . “\0″ . ” . “\0″ . ” . “\0″ . ”,
    ‘Keywords’ => ‘Here is a Tag’,
    ‘Subject’ => ‘This is the subject.’,
    ‘WINXP’ => ‘(ARRAY)’,
    )”

    (I don’t understand all the weirdness in “Comments” and “Author” but left it there in case YOU know what to do with that. 🙂 )

    I have the two boxes checked for Enable IPTC/EXIF Mapping. All of the following have NONE for IPTC value, EXIF for Priority and Replace.

    Title: template:([+xmp:Title+])
    ALT Text: template:([+xmp:Title+])
    Description: template:([+xmp:Subject+])

    It’s updating, but I can’t seem to get anything useful in the “Description” field. Is this because they are present in the ALL_EXIF result, but not in the ‘image_meta’ =>’ array?

    While I was typing this, I clued into the COMPUTED array and tried:
    template:([+COMPUTED:Comments+]) and template:([+COMPUTED.Comments+]) and
    template:([+COMPUTED:Subject+]) and template:([+COMPUTED.Subject+]) but I’m still getting “This is the Title” in the Description field.

    Well, I guess my basic setup isn’t correct to begin with. I just did “Map All Attachments, Standard Fields Now” and got:

    Waiting: 0, Complete: 1, Unchanged: 1, Succeeded: 0

    Good to hear from you again. Thanks for all the details you’ve posted regarding your metadata mapping adventures. It would be very helpful if you can post a link to the image file(s) you are working with so I can analyze their metadata and give you more specific help.

    EXIF fields like Comments and Author have some encoding problems, which is why the COMPUTED array is created by the PHP function that maps EXIF values. You can display the COMPUTED values by coding something like [+exif:COMPUTED,export+].

    XMP data varies quite a bit depending on the tool that added the data to the file. That’s another reason I’d like to have a look at the file(s) myself.

    By the way, did you work out the issues in your earlier topic Simple Menu Befuddlement? If so, I’d like to mark it Resolved.

    Thanks for these new questions and for your continued interest in the plugin.

    Hi, David! You’re so patient, I really appreciate it. I obviously have no clue what I’m doing, but I have made progress!

    First, yes, please mark the previous topic resolved.

    This is the link to the page I’m creating:

    http://cousin-collector.com/blog/?page_id=690

    Obviously, it’s only public now for you to view it, as you will soon see. 😀 But the site is lightly trafficked.

    The code I used for that page is:

    [mla_gallery]
    post_parent=all
    orderby=title
    columns=0
    category=photos
    post_mime_type=’image/jpeg’
    link=file
    mla_style=none
    mla_caption=”template:{+exif:ALL_EXIF+}<br /><br />{+title+}<br /><br />{+description+} (Tags: {+exif:COMPUTED,Keywords+}) ({+file_size,kbmb(m)+})”
    [/mla_gallery]

    (I want to import the “Keywords” as “Tags” so the “Private” keyword limits public access to those images, but I haven’t figured out how to do that yet.)

    If it helps, this is what I’m trying to do: I have thousands of photos and images related to my research. I’m trying to catalog them. The best way to do that is to put the info in the image metadata so it is preserved. Unfortunately, that’s not easily accessed in most image programs — I’m using FastStone. The metadata is also not easily searchable. Since the images are already on the server, I can import them into my WP installation and find/search them from there. Some can be public, but not all, so that’s one trigger I’m trying to work out.

    “XMP data varies quite a bit depending on the tool that added the data to the file. That’s another reason I’d like to have a look at the file(s) myself.”

    Yes, that became painfully evident with the different results I was getting. The metadata that you see on that page was done in the Windows Explorer window. There are fields at the bottom to enter the information easily — all the other programs I tried required a lot of mouse work and I’m a keyboard girl. LOL! Anyway, I’m getting consistent results doing it that way, as you can see, so now I just need to figure out how to import that info into the Media WP entry, or access and style it via the [mla_gallery] codes.

    I also know I need to use “template” but I’m still working on that, too. 😀

    It’s a slow work in progress. For instance, I need to enable “tags” in the setting, I think.

    Thank you so much for the help. I’m *almost* there. It seems at this point it’s just shortcode syntax issues. 🙂

    (Hope this isn’t TMI!)

    Also, ideally, I’d like to include my research documents here, too, that are in PDF format. I played with that a bit, but the metadata is *very* inconsistent there, and I had trouble sorting the different mime types by title? Thanks!

    Hi, David! Another problem I’m having with this is that the HTML in the mla_caption isn’t being read. I’ve tried various forms of “template” but I’ve got the syntax wrong. I *did* have this working at one point, but don’t know how I did it. 🙂 I think I do need to use “template” because I’ve now got JPEGs and PDFs on the list, and I read at one point that the parentheses make sure that if it doesn’t exist, it’s bypassed for that entry. Thanks!

    Hum — interesting. The HTML for is rendering, but the <br> and <br /> tags are not.

    That should have been the “strong” tag. FYI — I know the metadata for the PDFs is inconsistent. As with the image editor, I need to determine which PDF program includes the metadata I need. Simply exporting as PDF from OpenOffice doesn’t work. 🙂

    Thanks for your updates and all the additional information; very helpful. A couple of small changes to your shortcode parameters should help. Try something like this:

    
[mla_gallery mla_caption="{+template:{+exif:ALL_EXIF+}<br /><br />{+title+}<br /><br />{+description+} (Tags: {+exif:Keywords+}) ({+file_size,kbmb(m)+})+}"]
 post_parent=all
 orderby=title
 columns=0
 category=photos
 post_mime_type=image/jpeg
 link=file
 mla_style=none
[/mla_gallery]
    1. You need {+ +} delimiters around the template: prefix to make it a substitution parameter.
    2. Your Keywords are not in the COMPUTED array – they are in the EXIF elements.
    3. The <br /> tags are filtered out by some MLA logic that tries to repair WordPress editor/parsing issues. If you put the mla_caption parameter inside the [mla_gallery] shortcode this logic is bypassed, preserving the tags.

    Give the above suggestions a try and let me know how they work for you.

    David, you rock!

    I still have a lot of tweaking to do, and some more questions that I’ll try to find the answers for, but at this point I am no longer completely lost!

    AND I’ve finally found the “resolved” box!

    Thank you!

    Hi, David!

    I have a couple more questions:

    (1) Now that I’m using the correct “template” code (thanks!!) I can’t figure out how to get the parentheses to print. For the file size, I want it enclosed to set it apart: (163.757 KB). I’ve tried escaping a second set of parens, but that’s about it.

    (2) I’m getting the expected “404” error when trying to use the tags as links. They show up fine as tags, the links just don’t work. I found your previous post links about the WP limitations on Media stuff, and will be grinding through that soon enough.

    These I don’t know if you can help me with, but maybe you’ve come across them before:

    I’m using these entries for mapping:

    Category: template:([+pdf:Categories,array+]|[+exif:Keywords,array+])
    Tags: template:([+pdf:Keywords,array+]|[+exif:Artist,array+])

    and Priority: EXIF, Existing Text: Replace

    (2) In an attempt to make the process completely automated, I’m trying to process the keywords as tags on import. I *did* find the information to do this for both JPGES and PDFs (yay!).

    For the images, by default the tags are separated with semicolons (;). When I leave it this way, it doesn’t separate the array, the tag is imported as “Postcard;Private” literally. If I separate them with commas, they aren’t imported at all. Perhaps a limitation of using Windows Explorer to edit the metadata?

    (3) Since I didn’t have enough fields in the standard PDF metadata, I got tricky and created a custom field in the PDF: Categories. Unfortunately, not only doesn’t this get exported, it prevents the “Keywords” from being exported as well — pretty much messing up everything I’ve accomplished so far. 🙂

    Since it’s still early, and I’m working from just a few PDFs and JPEGs to edit the metadata and testing it, it’s a small matter to switch gears at this point.

    Perhaps just using tags or just using categories is the way to go? Any suggestions would be appreciated.

    Thanks!
