Title: Auto tag plugin for cpg1.5.x (automatically add existing keywords to pictures)
Post by: Αndré on June 24, 2014, 12:21:01 pm
This plugin has been created based on a feature request (http://forum.coppermine-gallery.net/index.php/topic,74611.0.html):
Example: I upload a photo of a church, and write the word "church" in the title or the description. Then cpg automatically scans for every word in the title and description fields, and check if one of those words already exist in the tag keyword list.
If the tag "church" already exists, it will be automatically added as a tag keyword for that photo.

It works exactly as requested. The "keyword list" is a list of all keywords that are added to pictures in your gallery. There's no configuration. The plugin checks for keywords each time you edit file information (editpics.php / edit_one_pic.php).

Great work on this. I think is a really useful plugin. In SEO terms tags are becoming ever more important.

Thanks, it works great and eases the process of adding photo details a lot.

My feedback:
Maybe the keyword's first letter should be uncapitalized, just in case it's at the beginning of a phrase or if it's a noun like in german.
I don't know if utf_strtolower() is a function which has already been defined in cpg core, but if I type "Chiesa" in the title, the result keyword is "Chiesa". I wonder whether "chiesa" should have been the expected result?

Dynamic suggestion (cfr. with Simple Tags for WP) would be a great feature in v1.6, even if I'm afraid it would require jquery.

That's a matter of taste IMHO. Some people like to have the keyword in lowercase, others like to have them as entered. An earlier revision of that plugin used to set the keywords in lowercase. This might be configurable.

Hi Andre! Is it okay to use this plugin if number of tags us quite large? I.e. thousand etc

Sorry, but I don't get what you're asking for.

I worry about gallery performance, as i understand it will search among the existing tags during every image editing, what if the number of tags would be really high (i.e. 1-2 thousand) would you recommend to use the plugin in this case?

I haven't tested that, but it shouldn't affect the overall performance significantly. I assume the number of existing pictures will affect the performance more than the number of different keywords. Feel free to post your results (have a look at the debug output while editing - actually, directly after you submitted the form - a picture or several pictures). If you edit several pictures at a time (editpics.php), the plugin only searches (i.e. query the database) for existing pictures once when submitting the form.

Hi Andre!

Debug logs are attached.
Also find the issue - plugin doesn't work for keywords separated by "space".
And additionally feature request - is it possible to keep it for single-edit page (not for multiple-edit)?

Sorry, i clarify: if one keyword has space inside i.e. Great Britain - doesn't work.

Page query time is ~ 100ms for single and multiple files edit. Looks good to me.

Correct, as the initial feature request was
scans for every word in the title and description fields
and words are separated by spaces ;) This could be changed by inverting the check, i.e. check if already existing keywords occur in the title and description.

is it possible to keep it for single-edit page (not for multiple-edit)
Should be possible, but I haven't checked that yet. I'll have a look when I try to fix the keywords with spaces issue.
