Increase character limit for keywords in OJS version 2.4.6

Hi - we are hosting a journal for which has rather long keywords associated with it, we are limiting them to 15 keywords but they still run out of room. Where can I increase the number of characters allowed in this field?
FYI, I don’t think we’ll be migrating to v3.0 anytime soon.
Thanks,
susan

Hi @mutanthumb,

Off the top of my head, OJS 2.4.6 doesn’t have a per-keyword limit, but may have a limit on the total list of keywords. Is that consistent with what you’re running into?

Total list, not per keyword.

Hi @mutanthumb,

There’s a limit of 255 characters written into the template that generates that form. See templates/submission/metadata/metadataEdit.tpl:

<input type="text" name="subject[{$formLocale|escape}]" id="subject" value="{$subject[$formLocale]|escape}" size="40" maxlength="255" class="textField" />

There’s a similar limit in the submission form. See templates/author/submit/step3.tpl.

Thanks Alec, can I change the limit without screwing things up?

Hi @mutanthumb,

I’m not sure I can answer that question definitively :slight_smile: but yes, you should be fine to change the limit in those two files.

After making a change like this, what do I have to do to make it “live”?

Hi @mutanthumb,

It should take effect immediately. If it doesn’t, make sure your file permissions are correct in cache/t_compile – it might be that OJS is having trouble recompiling the templates if the cache permissions are preventing it.

Hi Alec-
Here are the file permissions for t_compile:

drwxrwsr-x 2 apache apache 24576 Mar 5 13:36 t_compile

Hi @mutanthumb,

Those look fine (depending on your SAPI), but check that the same also applies to the files in that directory. You could try removing all .php files from cache/t_compile, and see if they’re regenerated as you use the system.
