Thanks for your question and for all the details you have supplied.
The WordPress failure to populate the caption field for new images is a long-standing complaint, and WordPress 4.3 contains an “enhancement” to resolve this issue. Your application suffers because WordPress doesn’t know about MLA mapping rules, which run after the initial WordPress logic.
If you already have an MLA IPTC/EXIF mapping rule for the Caption field, have a look at the “Existing Text” setting at the right-hand end of the rule. The default for this option is “Keep”, which means that MLA will not replace the new WordPress default value with your chosen IPTC value. Changing that setting to “Replace” might solve your problem. Don’t forget to scroll to the bottom of the screen and click “Save Changes” to record your update. After you’ve saved the change you can click “Map All Attachments, Standard Fields Now” to apply the rule to all your existing items. You can also find more selective mapping controls in two other places:
- In the Bulk Edit area of the Media/Assistant submenu table. Go to that screen and select one or more items by checking the box at the left of each item. Pull down the Bulk Actions list and select Edit. Click Apply, and the Bulk Edit area will open up. You will find the “Map IPTC/EXIF Metadata” in the bottom-right corner of the area.
- In the “Save” meta box at the top-right corner of the Media/Edit Media screen for an individual item. From the Media/Assistant submenu table, click on the item thumbnail or on the “Edit” rollover action to get to the Edit Media screen.
You can pick the mapping control you want to export one item, select a group of items or export all of the items in the Media Library.
Give the above suggestions a try and let me know if they resolve your problem. I will leave this topic unresolved until I hear back from you. Thanks for your interest in the plugin.
Thanks David. You’re first suggestion of setting the rule value to replace did the trick. I never thought to try that since the field was already blank, nothing to replace.
Thanks for a great plugin. Using it along side justified image grid and works well together.
Thanks for your update with good news and for the positive feedback on the plugin.
I am marking this topic resolved, but please update it if you have any other problems or further questions about mapping IPTC/EXIF fields to Media library items.
