Will a WordPress update affect my theme/database changes?

    Hi,

    We’ve recently created a members portal for one of our clients, and security is a big point for us. A slight oversight we made was customising the twentyfifteen theme itself, but I have changed the name of this theme, so I think there’s not reason to worry about an automatic update for the theme ruining what we’ve done so far.

    However, part of our edits included adding new fields for the user screen (address, telephone number e.g.). I’m concerned that by updating to the newest WordPress version (now 4.4.2) this will affect these custom fields, which are saved in the database.

    My understanding is that the recent WordPress updates are important for security, so I’m very keen to go through with them, but we really don’t want anything to change in regards to the custom database data. Could anyone let me know if our database is safe if we update?

    Thanks in advance.

    As long as the theme directory and theme slug in the style.css file is different then you should be fine.

    A child theme tends to be a more supportable solution though. ??

    What and where did you edit? If it’s in the core WordPress files (I hope it’s not) then you will have a problem.

    If you created your own tables then you should be fine. But as a precaution make sure you have a full DB and file backup off of your server before proceeding to update.

    If something goes tragically wrong then the DB and files will let you put it all back as it was before you updated.

    Thanks for the fast response Jan!

    I actually only change the name of the theme in style.css file, so I’ll have a look at that!

    And I know well enough not to touch the core files, and any new database fields were created in the functions.php file. I’ll definitely make a backup of the databases, but it sounds like it’ll be fine.

    Thanks again!

    Hi,

    Afraid I’ve got another question. The theme I’ve edited was twentyfifteen, and in the function.php it uses ‘twentyfifteen’ in quite a few functions. In regards to the theme update issue, if I simply copy that theme, change the file name and name in the css, upload that, and then activate it, is that a safe option??

    Thanks again.

    Change the theme folder name to something unique, and you won’t receive theme updates, nor will WordPress rewrite your theme on a core update.

    Hi Andrew,

    If I simply change active theme’s directory, will that break the site?

    Thanks

    I wouldn’t have thought so, but if it does you can name it back.
