QUESTION
I am using the code below to hide a list of plugins from admin dashboard.
...ANSWER
Answered 2022-Apr-07 at 16:40Something like this? Personally, I think that plugins should be hidden per default, and then they're unhidden if you're accessing it. This seems better when the majority of users is not you. But, here goes:
QUESTION
I want to modify how some code in Visual Studio 22 is generated.
For instance, in methods I can generate null check on using the Add null check (MS docs link) for arguments in the following way.
ANSWER
Answered 2022-Mar-25 at 17:29Rewriting an answer by canton7 from the comments:
The Add null check is not generated by any code snippet. Rather it is based on the standard analyzer infrastructure (defined here and seen here). This means it is just a semantically generated if statement with a throw inside of it. Then based on your .editorconfig (or defaults if not specified) it formates the code accordingly.
One is left with the following options:
- Edit the .editorconfig file to make the code format as pleased. Note that this approach applies globally.
- Wait for the C# 11
!!syntax. - Write your own analyzer and code fix (tutorial).
- Edit it by hand :).

Starting to build my first plugin and I'm completely puzzled on why the submenu page won't show? The main page shows up, not the subpage.
I've run over the syntax what feels like a million times and I just don't see the gap on what I have here. (Page markup is complete, not shown, I'm just trying to get the menu item to show up.)

QUESTION
I am trying to determine the Big-O notation of these code-snippets:
#1:
...ANSWER
Answered 2021-Dec-03 at 17:29The first one is indeed O(n). You rightly say that the while loop runs O(n) times, and everything within the loop is constant time*, so it does not matter how often the if-conditions are true.
The second one is more interesting. You're correct to point out that the faster decrease of b makes the function less complex. In fact, what this function does is increase a stepwise and then sets b to the appropriate value such that a*b==n, if such a b exists. This means that b can only change when a has changed, and so at least half the time that the loop is entered, a is altered. That is, the loop is entered a constant amount of times for each increase in a.
Now we only need to figure out how often a gets increased. The loop stops when a > b. Because b is equal to n/a, this means that the loop stops when a gets larger than the square root of n. Therefore, the function is in O(sqrt(n)).
* Actually the time it takes to divide, multiply and compare numbers can scale with the size of the numbers, but we'll ignore that for now, as it doesn't seem like that is the focus of the question.
QUESTION
I found this code here below and it adds a nice "Filter by Sale" drowpdown filter on Woocommerce admin product list.
Somehow this code has a conflict with the order editing page. If I open up an order for editing there is and error "Notice: Undefined index: post_type in /wp-content/plugins/code-snippets/php/snippet-ops.php(469) : eval()'d code on line 36"
Line 36 says: if (!is_admin() || $_GET['post_type'] != "product" || !$selected) {
IS there a way to fix the snippet to not mess with the order editing page?
This is the full code I am using.

QUESTION
I am trying to build a page that would just do three things:
- Make the user choose a file (a .json file to be specific)
- Simply Read the file's contents and store them in a variable. (do not store anywhere)
- Process the contents' variable further using Javascript. (I'll be using JS to convert the file into XML. I have the conversion code ready & working, it just needs the json string, which would be fetched from the file contents' variable. After converting to XML, I'll export the XML file so the user would download it, and import it in my MS Excel Sheet, which has XML mappings to populate data. [I am yet to figure the export option])
So far I have acquired some code-snippets to use in some parts of my code:

I am using Symfony 4.4 and trying to upload an image. But while creating schemas I am getting an Annotation error.
[Semantical Error] The annotation "@Symfony\Component\Validator\Constraints\Image\Image" in property App\Entity\Student::$photo was never imported. Did you maybe forget to add a "use" statement for this annotation?
Attaching the code snippets below, please say what is the mistake I made.use Symfony\Component\Validator\Constraints as Assert;
...ANSWER
Answered 2021-Jul-16 at 07:29It looks like you forgot to add use Symfony\Component\Validator\Constraints as Assert; to the top of the file.
According to the error message and the documentation for NoBlank, that line should fix your issue.
