Frequently Asked Questions

Common questions about Appointment Booking Calendar

A: The product's page contains detailed information about each appointment calendar field and customization: https://abc.dwbooster.com

A: For centering the calendar add the needed styles into the "Customization area >> Add Custom Styles" (at the bottom of the page that contains the list of calendars): .appContainer{text-align:center;} .appContainer2{margin-left:auto;margin-right:auto;width:200px} After that be sure to refresh the page that contains the appointment scheduler form or clear your browser cache to be sure that the browser is loading the updated CCS styles file.

A: To delete an appointment locate it into the appointment calendar in the settings area, clear the title (there is a button for that) and save it. This action will delete the appointment (even if the content wasn't cleared).

A: You can specify the size of the appointment calendar's cells, that way the complete appointment calendar width and height can be controlled. Open the file "appointment-booking-calendar\TDE_AppCalendar\all-css.css" and about line #139 modify the "padding" applied to the cells: .yui-calendar td.calcell { padding:.3em .4em; border:1px solid #E0E0E0; text-align:center; vertical-align: top; }

A: The "acknowledgment / thank you message" shown to the user after submitting the appointment form should be placed at the page indicated in the field "URL to return after successful payment". Note that after the submission the user is redirected first to PayPal and then to the "thank you" page once the payment for the booking has been completed.

A: Open the file "wp-content/plugins/appointment-booking-calendar/TDE_AppCalendar/all-css.css" ... find this CSS rule: .yui-calendar td.calcell.reserveddate { background-color:#B6EA59; } ...and replace the background color that appears there.

A: Please read the instructions on this Google page: https://support.google.com/calendar/answer/37100?hl=en To get the iCal feed URL right click the "iCal" link on the calendar list and click "Copy Link Address" or "Copy Link Location" (depending of the browser you are using). Note: This will automatically export the bookings stored in the calendar plugin to the Google Calendar. The inverse process (import the items on Google Calendar into the plugin) is available in the Platinum version of the plugin.

A: The Platinum version of the Appointment Booking Calendar supports double opt-in e-mail validation. The double opt-in process includes two steps. In step 1, a potential customer fills out and submits your online booking form. In step 2, they'll receive a confirmation email and click a link to verify their email, changing the status of the booking to "confirmed". The double opt-in e-mail validation is useful to comply the European General Data Protection Regulation (GDPR). More info at https://abc.dwbooster.com/documentation#doiemail-area Q: After booking appointment I'm not receiving the emails with the appointment data. A: Please check if after the completing the payment at PayPal the appointment appears registered in the appointment calendar (some time slot unavailable): If the appointment purchase is registered, then the problem is that you server has some additional configuration requirements to send emails from PHP. The Appointment Booking Calendar plugin uses the settings specified into the WordPress website to deliver the emails, if your hosting has some specific requirements like a fixed "from" address or a custom "SMTP" server those settings must be configured into the WordPress website. If the appointment purchase isn't registered, first check if you are testing the appointment booking form on a local website or in an online website. Note you should test this feature into an online website (local websites cannot receive PayPal IPN connections). If the appointment purchase isn't registered and you are testing it on an online website, then check if the payment appears as "completed" at the PayPal seller account (no red flags, no pending mark). Check also if your PayPal account is setup to automatically accept payments in the selected currency. The payment must be "accepted" and "completed" in the PayPal seller account.

A: Yes, it can be done through the automatic integration with the CP Referrer and Conversion Tracking plugin.

A: Add this CSS rule into the "Customization area >> Add Custom Styles" (at the bottom of the page that contains the list of calendars): .yui-calcontainer{width:98%}
