            Add new datastore during upgrade
            Asked 2020-Sep-01 at 15:25

            I want to migrate binary content from the segmentstore to a new datastore during an repository update. The current version of my repository is 1.6.1. It is using TarMK segmentstore, and has no datastore. In my experience, having binaries in a file datastore offers a considerable boost in performance. So that’s what I want to do with my upgrade to 1.26.0. But how does one copy binaries to a new datastore?

            This command migrates my content to the new repository. The application loads the content properly. But there is no datastore.

            I did this once a long time ago. Your command to split the repository looks correct. You can check the datastore folder after running the oak-upgrade tool to see if there are files created.

            Don't forget to create the needed configuration files to use the file datastore before starting Sling on the new (split) repository location.

            Create a org.apache.jackrabbit.oak.plugins.blob.datastore.FileDataStore.config file in the install folder which contains at least this property:

            PHP functions generate discordant results in WP frontend vs database
            Asked 2020-Sep-01 at 00:35

            I have this function that generates a chapter_id:

            ...

            ANSWER

            Answered 2020-Sep-01 at 00:35

            I think the reason the shortcodes work is because the person viewing the page is both the "member" user and the current user. But when you are updating the database, you are the current user and not the "member" user - however the code is still using the current users value (i.e. your data) to update the member user data.

            You can change your user_register function to accept the user_id as a parameter. Then:

            • if a user id is passed in (e.g. during the user registration from the add_action), that will be the member users id, so you select the chapter for that user.
            • if no user id is passed in (e.g. when using the shortcode), then the current users id will be used.

            This is what the fetch_chapter_id function should look like now - I've just added the user_id as a parameter (comment #1 in the code) and changed the code that sets this value (comment #2):

            In PHP how do I rename a string in one function and use the result in a second function
            Asked 2020-Aug-27 at 22:39

            Pardon me if this is ultrabasic, I'm fairly green to all this.

            I'm trying to fetch a string value (chapter name) from a wordpress database, use a php function to rename the value and then concatenate the renamed value with some other variables to create a member_id.

            Below is my current code (added to functions.php file) and I have 2 problems with it:

            1. From the 1st function, when I use the shortcode [member_chapter] in a page/post I always get PG no matter what value of chapter name was used to register. If I switch the order of the foreach statements, then I always get BB, i.e. I always get the return value of the first if statement no matter what chapter name is actually in the database.
            2. From the 2nd function I never get the chapter_id, instead the result is always like FAL--2020-1007, i.e. it doesn't add the chapter_id value generated from the 1st function

            I'd really appreciate any help.

            You have several mistakes! Please read more about program languages before writing programs. See PHP Tutorial

            In first function you used assignment operator (which is =) instead of comparison operator (which is == or ===). You must change it everywhere use if in your code. Furthermore, You use return function inside foreach. it means your foreach loop runs just once and then return. You must use just if instead of foreach and use Limit 1 in your sql. Or do whatever to do in your loop and avoid to else return blahblah. Your second problem related to your first because it probably $row->meta_value is null for your first record returned.
