Fix the deprecated PHP function create_function() in WordPress

Web development 0

Recently I found my self once again fixing another error with a plugin that I use.

The Essential Grid error that will crash your WordPress site. now for me this is best practice, i leave these lines of code in every config.php file:

				
					ini_set('log_errors','On');
ini_set('display_errors','Off'); 
ini_set('error_reporting', E_ALL ); 
define('WP_DEBUG', false); 
define('WP_DEBUG_LOG', true); 
define('WP_DEBUG_DISPLAY', false);

you will only need to change the

				
					define('WP_DEBUG', false);

from false to true

				
					define('WP_DEBUG', true);

to turn on WP_DEBUG, to show the error like this:

Deprecated: Function create_function() is deprecated in /wp-content/plugins/essential-grid/essential-grid.php on line 98

To fix this error, i change this

				
					add_action('widgets_init', create_function('', 'return register_widget("Essential_Grids_Widget");'));

to this

				
					add_action ( 'widgets_init', 'Essential_Grids_init_Widget' );
function Essential_Grids_init_Widget() {
return register_widget('Essential_Grids_Widget');
}

Warning: Please note that if you update your plugin or theme it will remove this fixes. Please notify the plugin author or theme author rather than making these changes yourself.

Add Copyright © Year in the WordPress Footer with Automatic Updates

Coding Tricks and Tips, Visual Hook Guide, Web development 0

Do you want the text Copyright © Year ‘2020’ to be updated to the current year automatically in your WordPress footer? The best way to this is create a shortcode – without any plugins. With this I will also bring you a few bonus date formats like current date, current month and current day.

Step 1. Enable shortcodes in WordPress widgets

Place these few lines of code in your functions.php . If you do not have a child theme , you should get one first.

This will be overwritten next time you update your theme.

 //Allow shortcodes in widgets

add_filter ('widget_text', 'do_shortcode');

Step 2. Create your shortcode for the current year (and current month, current date or current day)

Next step is to create one or more shortcodes that display today’s date. Copy the code below for the date formats you want to use and paste it in your  functions.php. You can place the code below the code you added in the previous step. Save.

//Display current year
function year_shortcode () {
$year = date_i18n (‘Y’);
return $year;
}
add_shortcode (‘year’, ‘year_shortcode’);

You will use [ year ] to display the year

2022

//Display current month
function monthyear_shortcode () {
$monthyear = date_i18n (‘F’);
return $monthyear;
}
add_shortcode (‘monthyear’, ‘monthyear_shortcode’);

You will use [ mounth ] to display the year

 [mounth]

//Display current date as YYYY-MM-DD
function yyyymmdd_shortcode () {
$yyyymmdd = date_i18n (‘y-m-d’); return $yyyymmdd;
}
add_shortcode (‘yyyymmdd’, ‘yyyymmdd_shortcode’);

You will use [ yyyymmdd ] to display the year

22-08-17

//Display current month and year
function monthyear_shortcode () {
$monthyear = date_i18n (‘F Y’);
return $monthyear;
}
add_shortcode (‘monthyear’, ‘monthyear_shortcode’);

You will use [ year ] to display the year

August 2022

//Display current day
function day_shortcode () {
$day = date_i18n (‘l’);
return $day;
}
add_shortcode (‘day’, ‘day_shortcode’);

You will use [ day ] to display the year

Wednesday

3. Add “Copyright © 2020 Company Name. All rights reserved.” in your footer

editing your footer should look something like this:

Copyright © [year] Company Name. All rights reserved.

 <?php if ( is_cart() ) {

Changing Rest Api Prefix to help to secure your website

Coding Tricks and Tips, Mobile Development, Technology, Web development 11

WP URL for the endpoints contain the prefix as well as a namespace.  Here is an example endpoint

http://example.com/wp-json/wp/v2/posts/1

That will fetch the details of all posts. The above example, “wp-json” is the rest url prefix while the “wp/v2” is the namespace.

If you don’t like the default base prefix and want to change it from ‘wp-json’ to something more beautiful, the code below will help you. In the code below, I have changed the base prefix from ‘wp-json’ to ‘api’.

/**
 * Modify url base from wp-json to 'api'
 */
add_filter( 'rest_url_prefix', 'dp_api_slug');
 
function dp_api_slug( $slug ) {
 
    return 'api';
}

you can change the return ‘api’; to return ‘any-custom-prefix’;.

Once you put the above code in your theme’s functions.php or in a plugin, Please visit the Dashboard->Settings->Change your permalinks( You can restore it after saving again, we need to change it at least once to flush the rewrite rules ).

So your URL example will look like the following:

http://example.com/wp-json/wp/v2/posts
