kandi X-RAY | acf Summary

acf is a C library. acf has no bugs, it has no vulnerabilities, it has a Permissive License and it has low support. You can download it from GitHub.

This C library contains core components on which other higher level libraries and applications can build. We have packaged some of our "common" code used by applications in the real-time platform; that is the original basis for ACF. However, that’s only a small portion of the fundamental code we use in production, and it’s not clear that the current packaging approach is the best way for us to reuse code while allowing users to decide how much they would like to opt in our internal framework. We thus decided to publish most of the remaining shared code under common/, despite the lack of packaging. Suboptimal packaging should not stand in the way of progress, and it should be easy for others to copy from common/ and remove AppNexus-specific noise. Our goal with this initial code dump is to share read-optimised data structures implemented in C. The implementation is usually not all we dreamed of, and the dependency graph is sometimes unreasonable. However, the code has proved its mettle in production, builds to our real needs, and is known to not be overly bug-prone for users. We don’t doubt that others have similar solutions to similar problems, and we hope that we can all learn from each other, even if we can’t always immediately use one another’s code. Eventually, all that should be nicely packaged in the ACF library. In the meantime, we’d rather share as much as we easily can, even if the source has unimportant dependencies on unpublished, more specialised, support code. We also have some other code that requires more buy-in, but that we either feel can be useful to others, or must be present to make sense of the more generic data structure and algorithm code. The files in src/ and include/ is the small subset that we mostly extricated from our internal never organically designed framework. Other files that we feel are worthwhile to share in their current state are in common/. One day, common/ will be empty and its contents in src/ and include/.

            The 422 error code is about the server unable to process the data you are sending to it. In your case, your table field is longtext when post.acf.attachments seems like an object. That's why it saves [object Object] to your db (It is the return value of the toString() method).

            How to use $(this) in jQuery when it's not yet defined?
            Asked 2022-Apr-08 at 09:20

            I have a piece of jQuery code which I need to only show one or the other div depending on whether the user wants to use a video file or embed a YouTube video.

            For context: I am building a website in wordpress with ACF blocks. I have created a button group, where the user can click "YouTube video" or "video file" in the WP Dashboard and based on this, different ACF fields will appear and also based on this, a different html code is needed to show the video on the front end.

            The issue now is that I have put both html codes in a div wrapper (the module that opens to show the video) but based on the selection from the WP Dashboard, only one of the videos (YouTube embed or video file) should be played. So I need to hide the other div.

            Technically, I have achieved that but the issue is now that I want that the user can use this block multiple times on one page, if they would need to have one block with an embedded YouTube video and one with a video file, then the code I currently have would apply to both fields, causing that both divs are hidden, not just one.

            So, my idea is to use $(this) in my jquery code to only apply that code to the current selector but every option I tried is not working.

            So here is the code I have working:

            You don't need a reference to this to do what you need.

            As you know the class of the parent element and the dynamic value from the PHP code before runtime you can use a selector and hide() them directly. This selector will work for multiple instances of these classes.

            Some notes regarding your code attempt:

            • No need to overwrite template files, you can use the woocommerce_email_order_details hook and then target the correct email notification via $email->id
            • get_comment() retrieves comment data given a comment ID or comment object. To get order notes you can use wc_get_order_notes() or $order->get_customer_note() to get the customer note during checkout.

            I have a WooCommerce site and in the single product page I have a custom checkbox to agree to terms before the add to cart button, but I am trying to add a true/false field in the dashboard so that this checkbox can be moved to a different position on the page.

            Answered 2022-Feb-25 at 10:03

            While acf/init is similar to the WordPress init action, I wouldn't use it.

            Init hooks are performed constantly.. since you want to apply an action on the single product page it's best to use a hook that only applies to that page, and will only run on those kinds of pages.

            For example you can use the woocommerce_single_product_summary hook. It might also be useful to test fields by hard coding before retrieving them.

            R: Finding code with authors' comments, if any
            Asked 2022-Feb-15 at 04:49

            Is there any reasonably simple, straightforward function along the line of getAnywhere() which returns the source code of a function with any comments, such that if I see no comments I can be confident that there are none, whether the code is in R, c, c++, Fortran, or something else? For example, stats:::plot.acf does not seem to have any comments in it. Can I conclude from this that there are no comments on its text?

            I understand that there is a flowchart-like search process where if you know that source is written in R, then that source including comments is available from a specific github repository via some search method appropriate tp gethub. Also if you have determined that code is in some specified other language it is available via a more elaborate search process that involves finding the correct file and then doing text search within it, different for base and contributed packages. I am under the impression that at least until recently there was no shortcut to learning and working your way through that implicit flowchart search method if you wanted to learn whether there is a version of the code which contains comments. Moreover, I believe that that versions of the code which do or don't contain comments were nowhere identified as such, except by the comments themselves or by prior knowledge.

            However, R is a pretty rapidly evolving ecosystem and I don't think it is entirely unreasonable to hope that simpler tools for determining whether there is a version of the source that includes comments, and finding it if there is, might now exist. Do they?

            Answered 2022-Feb-15 at 04:49

            Whether the source code of an R function is preserved internally (via its srcref attribute) depends on the value of option keep.source when the function is defined. By source code, I mean the code as entered by the user, with comments, possibly inconsistent indentation, possibly inconsistent spacing around operators, etc.
