After purchasing the plugin, unzip the received archive. It will contain: plugin archive, documentation, license. On your site, go to the plugins section – “Add new”. Next to the “Add Plugins” heading, click the “Upload Plugin” button. Select the plugin archive and click install. If a free version of the plugin is already installed on your site, first disable it. After installing the plugin, click “Activate”. The plugin is ready to go. In order for everything to work correctly, you should definitely add services and employees. After adding, place the shortcode [oz_template] on the page where you want to see the booking form.

Services – Add, Configure

After installing the plugin, add services. Adding services is like adding standard posts or pages to WordPress

In services, be sure to fill in the following fields:

Optional fields:

After filling out the service, click the Publish / Update button.

Employees – add, configure

After adding services, you can start adding employees.

For employees, be sure to fill out the following fields:

Optional fields:

After filling in all the fields, click the Publish / Update button. After that, a calendar will appear on the employee’s editing page with his schedule and his appointments.

Schedule settings

The plugin provides three types of schedules:

Constant schedule – to add such a schedule to the employee, select it, click the “Add a new line” button, select the days of the week and the time period in which the employee works. After filling in all the fields, click the add button. If an employee works on different schedules on different days, then you can click the “Add a new line” button again and indicate what hours the employee works on other days. Do not forget to publish the employee after adding / making all changes to the employee.

Shift schedule – This schedule is suitable for employees whose work cycle is constantly repeating. For example, an employee always works 2 days in a row, and then rests for 2 days in a row. To add this type of schedule, select it in the list. Click the “Change” button. We indicate the first number is the number of working days, the second number is the number of days off. We indicate the date of any first work shift so that the plugin can begin the counting of the schedule shift. And the working time, after which we click the “Add” button. Do not forget to publish the employee after adding / making all changes to the employee.

Custom schedule- if an employee always works differently, then choose this type of schedule. On the calendar, note the necessary dates and indicate the time of work on these days. Do not forget to publish the employee after adding / making all changes to the employee.

Breaks and daysoff

The plugin allows you to set breaks in the employee’s work schedule (for example, lunch break). The functionality for adding breaks is very similar to the functionality for adding a constant work schedule: select days, assign a break range, add a break.

The daysoff functionality is needed in order not to change the employee’s schedule in case the employee, for example, takes a vacation, gets sick or takes leave. To do this, mark on the daysoff calendar the dates on which the employee will be unavailable.

Adding a personal account for employees

This functionality is designed so that employees can receive individual sms and email notifications when customers book an appointment for them to the service. Also, this function allows an employee to edit information about himself / herself, change his work schedule, and also assign his Google calendar to his account. In order for this functionality to work, you must enable the option in the settings of the plugin “Add page for employees” – the tab Main settings. After that, you need to restart the plugin (in the plugin settings, first deactivate, and then activate the plugin).

Important! Check WordPress permalinks settings (General – Permalinks). Common settings should be: Post name. In any case, save these settings again (if you see 404 error on the employee’s page)

After enabling the option, create employee accounts in the WordPress system (Users – Add). Specify the role – Employee.
After that, go to the employee’s page and indicate which account should be assigned to the page of the selected employee. Employees who have access to an account on your site will only see their pages. If possible, they can specify their phone number for sms notifications, email, as well as assign a Google calendar account to receive information about new appointments directly to the calendar.

Employee’s personal account and registration form

Starting with version 3.0.5, our plugin has a more convenient personal account for an employee. To start using it, you need to create a blank page (in the pages section). The name can be anything, for example – Employee’s personal account. After that, go to the settings of our plugin and find the option “Employee’s personal account page”. In it, you must select this page – Employee’s personal account. After that, if you go to this page, you will see either a calendar and employee settings (if you are authorized on the site) or a registration / authorization form.

2. After the lines containing your database credentials, add the following lines:

define('ALTERNATE_WP_CRON', true);
define('DISABLE_WP_CRON', true);

3. On your hosting add a new cron task – every two minutes run this command wget -q -O - https://YOUR_SITE_URL/wp-cron.php?doing_wp_cron >/dev/null 2>&1
