Examples
Example 1: How to get the current timezone string in WordPress
<?php
$timezone_string = wp_timezone_string();
echo $timezone_string;
?>
This code snippet retrieves the current timezone string set in the WordPress settings using the wp_timezone_string function and then echoes it to the screen.
Example 2: How to check if a timezone string is set in WordPress
<?php
$timezone_string = wp_timezone_string();
if ($timezone_string) {
echo 'Timezone string is set: ' . $timezone_string;
} else {
echo 'Timezone string is not set';
}
?>
This code snippet uses the wp_timezone_string function to retrieve the current timezone string, then uses an if statement to check if the string is set. If it is set, it echoes the string, otherwise it echoes a message indicating that the timezone string is not set.
Example 3: How to set a default timezone string in WordPress if none is set
<?php
$timezone_string = wp_timezone_string();
if (!$timezone_string) {
$default_timezone = 'America/New_York';
update_option('timezone_string', $default_timezone);
echo 'Default timezone string set to: ' . $default_timezone;
} else {
echo 'Timezone string is already set: ' . $timezone_string;
}
?>
This code snippet first checks if a timezone string is set using the wp_timezone_string function. If it is not set, it sets a default timezone string to ‘America/New_York’ using the update_option function and echoes a message indicating the default timezone string has been set. If a timezone string is already set, it echoes the current timezone string.
