问题 I want to check if a Woocommerce product was created less than 60 days ago. - If true, do something. I am obtaining the date the product was created in backend/admin using the official Woocmmerce function $product->get_date_created . My code partially works, but it seems to be checking if $product->get_date_created literally contains the value 60 instead of perfoming the calculation and minusing 60 days from the current DateTime . I have come to this conclusion because my IF statement runs

问题 I am not able to understand the purpose of piped i/o streams in java. If I write something using an outputstream, I can anyways read it again using an inputstream. So what is the need of a pipedstream? 回答1: Short motivation: Separation of concerns (always good - in this case it helps split your code into reading and writing part) Multithreading (previous point lead to "easy" (its never easy :D) parallelization) Long explanation/example: Imagine you have "producer-consumer" like application.

问题 I'm trying to make a massive delete, in order to do that I have an Array<number> of the ids I want to delete. I can't pass this array as a parameter to the method this._httpService.delete(uri,options) . The type of _httpService is Http . So I'm looping the array and inside the loop I'm making single calls, but each call is async and I have certain logic to run when the loop ends. 回答1: Actually you can send the id array in the body of a DELETE request, according to this answer, like so: http

问题 I am trying to implement a basic custom Auth provider in my server side blazor project, but I am having some difficulty implementing the 'IsAuthenticating' property correctly. I used this site as my starter point, but it throws an error if ' IsAuthenticating ' is set to true (more specifically when I return null from GetAuthenticationStateAsync() ). https://gunnarpeipman.com/client-side-blazor-authorizeview/. Specifically this line of code: if(IsAuthenticating) { return null; <---- This line

问题 I have the JSONView extension installed on Chrome, how do I actually use it to view the JSON tree for a particular website? The only options I see are "copy path" and "copy value." 回答1: I don't get your question, the JSON tree for a particular website ?

问题 I'm using the following function to search for words in a text file. The problem is that this function is case-sensitive. I don't want it to be case-sensitive! How can I make the function case-insensitive? $url = 'files/file.txt'; $thedata = file_get_contents($url); $lines = explode(PHP_EOL, $thedata); $search = 'some search words'; $pattern = preg_quote($search, '/'); $pattern = "/^.*$pattern.*\$/m"; if(preg_match_all($pattern, $thedata, $matches)) { echo implode('<br>', $matches[0]); } else

问题 Based on this documentation you can easily create a user email verification when someone signing up by them self, but how to send an email verification when admins created the account for their users? I already tried with this approach <?php namespace App\Http\Controllers; use Illuminate\Http\Request; use Illuminate\Support\Facades\Hash; use Illuminate\Foundation\Auth\VerifiesEmails; class TeacherController extends Controller { use VerifiesEmails; ... // Other basic functions public function
