This is really more of a JavaScript question than a WordPress question. You just happen to be running it on a WordPress hook. In the future you will have better luck posting this type of question on StackOverflow. However, I will note that document.querySelectorAll is not a live updating list. When you call it, it … Read more
You could poke around in the Network tab. Filter the requests by XHR. You can view the headers and the Response from there. I think I read somewhere that error reporting is something Gutenberg dev is planning on improving in the future.
Ideally, you can access those headers with response.header, but not all headers are available publicly unless exposed manually. In your case, to access X-WP-Total by the client, you need to set the Access-Control-Expose-Headers header on your server: Access-Control-Expose-Headers: X-WP-Total
The problem is that your code is inside the <head> element, but the code is trying to access document.body which won’t exist at the time that your script is run. If I recall correctly you’re supposed to place this code immediately after the opening <body> tag. To do this from functions.php your theme needs to … Read more
Just define the function in its own separate JS file, and load that file alongside the page-specific files. The “WordPress way” would be to register the script containing the shared function(s) and then set it as a dependency of the other scripts: wp_register_script( ‘my-functions’, get_theme_file_uri( ‘js/functions.js’ ) ); if ( is_page( 1 ) ) { … Read more
YOu need to do a full cleanup of your site, including changing all credentials (hosting, FTP, admin users) updating everything (WP, themes, plugins); perhaps even installing via FTP check every file for inserted code: index.php, wp-settings.php, wp-config.php change credentials on the database (strong passwords!) look at htaccess file, and any hidden files. My procedure is … Read more
It was Cloudflare Rocket Loader option which caused this. I disabled Rocket Loader and it has gone. Edit: In the Cloudflare support page is this very clear note and it explains all: So, before I validate the page I disable it in order to avoid useless warnings and then I turn it on again.
Yes and no, it depends… The WP Scripts package depends on the @wordpress/dependency-extraction-webpack-plugin package at: https://github.com/WordPress/gutenberg/tree/master/packages/dependency-extraction-webpack-plugin What this will do is search for packages from @wordpress and list them in a file to make it easy for you to load the list of dependencies when enqueuing. It also adjusts webpack so that it knows not … Read more
Because until relatively recently WordPress supported PHP 5.2+, but that constant was only added in PHP 5.4. Given that wp_json_encode is meant to encapsulate and account for the differing behaviour of json_encode across multiple PHP versions, it doesn’t make sense to deliberatly change its behaviour for PHP 5.4+ Now that WordPress has raised its minimum … Read more
that’s because you have defined the variable theUser as null and overridden the one that has the object before then you have tried to call the object. just remove this line var theUser;
