How to Modify HTTP Headers in the WordPress Admin Area

WordPress provides the wp_headers filter hook and send_headers action hook to add and modify HTTP requests. For front-end pages, these are ideal hooks that should be used whenever possible.

WordPress Error Fix: “Call to undefined function get_header()”

[ Call to undefined function ]

I’m seeing a big increase in bot attacks targeting theme files directly. First they get the URL to your theme directory. There are numerous ways for a bot to get this information. For example most themes include assets like CSS and JavaScript files, and the link includes the full URL. So then once they have the theme URL, bad bots will make direct requests for well-known theme template files, like index.php and header.php. Requesting template files directly may reveal possible […] Continue reading »

Enable PHP fsockopen with CSF

[ Mr. PHP fsockopen CSF ]

Recently started some sites with Liquid Web hosting, everything going extremely well all around. There was one hiccup (at least for me) where PHP’s fsockopen was not working. At the time, I was trying to figure out why the Whois Lookup feature used by Blackhole Bad Bots was not working. Initial investigation revealed that fsockopen() external HTTP requests were getting blocked somewhere. Everything else worked, including making the requests via cURL. Continue reading »

Activate WordPress Plugins via the Database

Recently a reader named Chris asked, “how can we turn ON a plugin from the database?” He mentioned reading my previous article, Quickly Disable or Enable All WordPress Plugins via the Database, but for circumstantial slash technical reasons needed to do the opposite and enable a plugin directly via the WordPress database.

X Theme Leftover Code Snippets

While working on the site’s 24th redesign, I ended up with about 10 code snippets that were awesome but ultimately not needed. So rather than just delete these tasty functions, I am posting them here for future reference. Who knows, during the next site update I may decide to implement or repurpose some of these techniques.

Delete Shared/Saved Gutenberg Blocks

Been playing with WordPress new Gutenberg functionality. While exploring the new features, I created some Shared blocks via the “Convert to Shared Block” button. After another hour of playing with the Gutenberg API, there were a number of “orphaned” Shared blocks (just due to swapping out code snippets while testing). After some searching, I found it is possible to delete Shared blocks programmatically with JavaScript, but could not find any specific documentation or examples.
