An important reminder to include following header while sending data in Javascript fetch() call in JSON format.
Also, do not forget to use JSON.Stringify().
var data = { some_data: ABC};
headers: {
'Content-Type': 'application/json',
},
body: JSON.stringify( data ),This is not needed if you are creating a form data object and appending data to it.
var data = new FormData();
data.append( 'some_data', 'ABC' );Sometimes you may face a problem when you have to decode a string with Javascript which was originally url encoded with PHP. This can be an API response or cookie set by PHP setcookie function.
A simple way to do this is through decodeURIComponent function in Javascript. But it leaves the "+" signs in the string. For that we can use replace function to replace all the "+" signs with space. Remember, simply using replace function sign will only replace the first occurrence in the string. To replace all the occurrences, use the regex version with g flag.
Here is the code for your reference-
var decodedString = decodeURIComponent( encodedString ).replace( /+/g, ' ' );Here encodedString is the url encoded string received from PHP.
Its that simple!
If you have any other method, do share in comments.
Happy coding!
