With simple plugin we can create responsive adsense ad shortcode and put it anywhere inside our WordPress post.
Here is how to create it.
The usage is easy. Just put [responsive_adsense] anywhere inside your post, and responsive adsense ad will appear there.
Another shortcode in our code – [responsive_adsense_single] is for cases if you want those ads to appear only in single page (not in another pages where post content shown)
There are obviously a lot of ways to block our WordPress admin area login page from attackers, there are a lot of plugins for that.
But what if we want to build own logic – the secret key which changes itself daily, but we always know it, because we know its built logic.
For example what about if our secret key to wp-admin is today’s date + any custom string? Funny yeah? Or md5 encrypt of today’s date + any custom string – in this case nobody will recognize how this keys are generated.
Let’s write a little 2 functions which fulfill this solution.
In this sample our logic is ” secret key is current date + sesame” , so for example if today is 2016-10-10, our secret key would be 2016-10-10-sesame.
So yoursite.com/wp-admin?call=2016-10-10-sesame will work, yoursite.com/wp-admin will give 404 error.
You can also build your own funny logic which changes keywords by the current date, last post name or any other dynamic data. Or to hide how your key is built you can use md5 encryption for that.
For that purpose just use $secretstring = md5(date(‘Y-m-d’) . ‘-sesame’) in the code above.
If we want to use external mail servers for sending mails via our website, we can do it without any plugin.
And also we can build simple function which can use several mail servers for each case.
For example, it may use different mail server when it sends something via cron jobs, another mail server when it send something via contact form etc..
It is not about to change email headers like “email from”, “sender name” – to do it is much easier.
I mean real external mail server with different mail server hostname, port, user and password.
1. In first one it gives a code to use single external mail server.
2. In second one it gives ability using randomly chosen multiple mail servers. (could be helpful when mailservers have some sending limits)
3. In third one it gives ability chosing mail servers for specified cases.
If you want to check this inside the some hook, which runs after plugins_loaded hook, it is very simple. Just check some plugin specific constant or function exists or not.
For example, to check WooCommerce we will need to check any WOO constant is defined or not. Or it is enough to check if class WooCommerce exists or not.
But what if you want it to check it before the plugins loaded? In this case you will not be able to check some constant,function, class of the plugin is defined or not, because they are not loaded yet. So we will need some additional trick for that. We can check $wpdb->options table and get the list of active plugins, process it and get the results. Let’s see how it works.
Here is sample code for that:
Backend gets the first requests and does some operation and returns done percentage. (in this sample there should be 10 steps, so each requests completes the next 10%).
