Added cron example for WordPress in readme, fixes #34

[natanael-aguiar]

It's a little help, lately I needed to add the WordPress cron to DDEV-CRON and I had a lot of difficulty, here is a simple example. Added the cron example for WordPress in the readme.

Basically it will run the WordPress scheduler every 15 minutes and will also create a log file in the root of the project. If you didn't want the log file to be created, just remove this part of the code 2>&1 | tee -a /var/www/html/cron.log

How wonderful, what is the next step now, do I need to do something on my side?

Thank you for the PR @natanael-oliveira .

I've never used WP so it was a good oppurtinuty to test the guides.

After following your PR, it does create cron.log, as expected, so ddev-cron is working with your guide.
However, cron.log contains the following line:

PHP Warning:  Undefined variable $table_prefix in /var/www/html/wp-settings.php on line 127
Warning: Undefined variable $table_prefix in /var/www/html/wp-settings.php on line 127
Error: Error establishing a database connection.

Is this something I should be worried about?

@tyler36 Can you send me a complete screenshot of your wp-config.php file? From my experience it seems that there is a configuration missing from this file, but nothing related to the change I made.

I uploaded the file as a gist: https://gist.github.com/tyler36/d0cccbaf3ddd4f5c420aeb3f19ca40c0

So @tyler36 from what I saw your wp-config file is missing the database connection entries, but as you can you are using ddev it usually also creates another connection file called wp-config-ddev.php, but basically you need have these definitions for connecting to the bank, I will leave an example code:

`<?php
/**

• The base configuration for WordPress
• The wp-config.php creation script uses this file during the installation.
• You don't have to use the web site, you can copy this file to "wp-config.php"
• and fill in the values.
• This file contains the following configurations:
• • Database settings
• • Secret keys
• • Database table prefix
• • ABSPATH
• @link https://wordpress.org/documentation/article/editing-wp-config-php/
• @Package WordPress
  */

// ** Database settings - You can get this info from your web host ** //
/** The name of the database for WordPress */
define( 'DB_NAME', 'database_name_here' );

/** Database username */
define( 'DB_USER', 'username_here' );

/** Database password */
define( 'DB_PASSWORD', 'password_here' );

/** Database hostname */
define( 'DB_HOST', 'localhost' );

/** Database charset to use in creating database tables. */
define( 'DB_CHARSET', 'utf8' );

/** The database collate type. Don't change this if in doubt. */
define( 'DB_COLLATE', '' );

/**#@+

  define( 'AUTH_KEY', 'put your unique phrase here' );
  define( 'SECURE_AUTH_KEY', 'put your unique phrase here' );
  define( 'LOGGED_IN_KEY', 'put your unique phrase here' );
  define( 'NONCE_KEY', 'put your unique phrase here' );
  define( 'AUTH_SALT', 'put your unique phrase here' );
  define( 'SECURE_AUTH_SALT', 'put your unique phrase here' );
  define( 'LOGGED_IN_SALT', 'put your unique phrase here' );
  define( 'NONCE_SALT', 'put your unique phrase here' );

/**#@-*/

/**

• a unique prefix. Only numbers, letters, and underscores please!
  */
  $table_prefix = 'wp_';

/**

  define( 'WP_DEBUG', false );

/* Add any custom values between this line and the "stop editing" line. */

/* That's all, stop editing! Happy publishing. */

/** Absolute path to the WordPress directory. */
if ( ! defined( 'ABSPATH' ) ) {
define( 'ABSPATH', DIR . '/' );
}

/** Sets up WordPress vars and included files. */
require_once ABSPATH . 'wp-settings.php';`
