By default, WordPress adds <link rel="shortlink"> meta tag to the <head> of a website and uses the short url like https://mixable.blog/?p=12345 for this. When you already use nice slugs as permalink structure, such a tag is not necessary, because you already have unique urls.
To remove the shortlink tag, you can use an additional plugin or simply add some code to your themes functions.php:
There are multiple ways to remove an element from an array in PHP. The simplest one is the method unset().
unset()
The method unset() can be used to remove a single element of the array:
PHP
$myArray = ['apple', 'banana', 'cherry', 'date'];unset($myArray[1]); // Remove the element at index 1 (banana)$myArray = array_values($myArray); // Re-index the array if you want to remove the gapprint_r($myArray);
This function can be used to remove a portion of an array and replace it with something else. If you want to remove a single element, you can specify a length of 1:
PHP
$myArray = ['apple', 'banana', 'cherry', 'date'];array_splice($myArray, 1, 1); // Remove 1 element starting from index 1print_r($myArray);
array_diff()
You can use this function to create a new array with all the elements of the first array that are not in the other arrays:
This error happened after moving a WordPress installation to another server. The new server had a different linux distribution and a newer PHP version. In my case, the environment changed from PHP 7.4 to PHP 8.2.
I already added some missing PHP extensions and updated the configuration to match the old one, but the error still exists.
At the end, this could be solved by adding the following code in wp-config.php file:
The Espressif tools contain a binary called xtensa-esp32-elf-addr2line which will decode the backtrace addresses and return details about the source files, lines and function names, etc.
By default, FutureBuilder provides a single future parameter that handles a single Future. For multiple Futures, we can combine them into a single Future using Future.wait. Here’s a step-by-step guide on how to do this:
Create a list of Future objects
Create a list of Future objects that represent the asynchronous operations you want to perform. For example, let’s assume you have two futures:
Future<String> fetchFirstData() async {// Simulate a network request or other asynchronous operation.awaitFuture.delayed(Duration(seconds: 2));return"First Data";}Future<int> fetchSecondData() async {// Simulate another asynchronous operation.awaitFuture.delayed(Duration(seconds: 3));return42;}
Combine the futures using Future.wait
Use the Future.wait method to combine the individual futures into a single future. Future.wait takes a list of futures as an argument and returns a single future that completes when all the input futures have completed.
Now, use the FutureBuilder widget to handle the combined future and display the results in your widget tree. You can place this widget in your build method.
classMyWidgetextendsStatelessWidget {@overrideWidgetbuild(BuildContext context) {returnFutureBuilder( future: fetchData(), builder: (context, snapshot) {if (snapshot.connectionState == ConnectionState.done) {// Use the results from the futures here.if (snapshot.hasError) {returnText("Error: ${snapshot.error}"); } else {returnColumn( children: [Text("First Data: ${snapshot.data[0]}"),Text("Second Data: ${snapshot.data[1]}"), ], ); } } else {// While waiting for the futures to complete, you can show a loading indicator or placeholder.returnCircularProgressIndicator(); } }, ); }}
In the code above, we use the snapshot to check the connectionState. When the connectionState is ConnectionState.done, it means that both futures have completed. You can access the results using snapshot.data.
Remember to replace the fetchFirstData and fetchSecondData functions with your actual asynchronous operations. This example demonstrates how to use FutureBuilder to handle multiple futures in a single widget in Flutter.
To use a specific port with the mysqldump command, you can provide the --port (or -P) option followed by the port number you want to use. The --port option specifies the TCP/IP port number to use when connecting to the MySQL server.
When using -P remember to use an uppercase P, because the lowercase option -p refers to the password.
Here’s the general syntax of using mysqldump with a specific port:
PORT_NUMBER: The specific port number you want to use (e.g., 3306).
USERNAME: Your MySQL username.
DATABASE_NAME: The name of the database you want to dump.
dump.sql: The name of the file where you want to save the database dump.
After executing this command, you’ll be prompted to enter your MySQL password. Once you provide the correct password, the mysqldump command will connect to the MySQL server using the specified port and create a dump of the specified database.
In JavaScript, escape(), encodeURI(), and encodeURIComponent() are three functions used to encode strings for different purposes. Each function serves a distinct purpose, and it’s essential to understand their differences:
escape()
The escape() function is used to encode a string so that it can be safely included in a URL query string. It encodes special characters, except for alphanumeric characters and the following set of symbols: @*_+-./. The main drawback of escape() is that it does not encode all characters, and it’s considered deprecated in favor of encodeURIComponent().
The encodeURI() function is used to encode a complete URI (Uniform Resource Identifier) but leaves the special characters used in the query string (?, &, =, etc.) untouched. It is primarily used to encode the main part of a URL, such as the protocol, domain, and path.
The encodeURIComponent() function is used to encode a component of a URI, such as a query parameter, fragment identifier, or any part that needs to be included in the query string. Unlike encodeURI(), this function encodes all special characters to ensure they are safely passed as parameters in a URL.
Use escape() for encoding a string to be safely included in a query string, but it’s deprecated and not recommended for general use.
Use encodeURI() for encoding a complete URI (protocol, domain, path) but not the query string parameters.
Use encodeURIComponent() for encoding individual components (e.g., query parameters) of a URI to ensure all special characters are encoded properly. This is the most commonly used encoding function for URLs.
