Values stored in wp_postmeta OR wp_acf_values

Hi,

I recently took over a project from a colleague who has left our company (so I cannot ask him for his insight) and discovered something weird:

For every post created after some day in mid-April it’s acf values are stored in a table called wp_acf_values, newer posts store them in wp_postmeta.

So my problem is this: my theme reads the values with get_field(‘xxx’) which apparently only reads wp_postmeta. So for new posts I can use custom fields in my theme, but my older posts are somewhat broken.
Is there maybe a function that reads wp_acf_values, so I can do a quick fix like this?

$value = get_field('xxx');
if ($value == '') {
$value = read_from_wp_acf_values('xxx');
}

Thanks in advance,
I hope that was somehow understandable

Hi @Maiwerk

I believe the wp_acf_values table was used in version 1 or 2, not 100& sure as it has been so long since then.

Version 3 and 4 definitely use the standard postmeta table, so this is why your older posts and newer posts use different tables.

I would imagine that the version 3 plugin would have included an update script to migrate across all the data.

Can I ask you what version of ACF did it originally use, and what version does it use now?

To find a function such as read_from_wp_acf_values, you will need to download an older version of ACF which contains the logic to use this table and then do a copy / paste into your functions.php file.

That said, It would be smarter to just migrate across the data. I would recommend that you dig through the source code of v3 and find the update.php file which contains the migration code.

Good luck

Thanks
