Translation

Some phrases used inside addon you can change/edit from admin settings, whole rest you will find inside that file: language\en-GB\en-GB.tpl_shaper_salon.ini

Translate the strings to your language and save them as with native language prefix and copy to your language folder. File (.ini) must be saved as UTF-8 without BOM encoding. You don’t have to translate all strings from that file, select only those you really need. For example only those phrases:

COM_SPPAGEBUILDER_ADDON_APPNT_FORM_SUBJECT="Select Category"
COM_SPPAGEBUILDER_ADDON_APPNT_FORM_PACKAGE="Select Your Package"
COM_SPPAGEBUILDER_ADDON_AJAX_CONTACT_PH_NAME="Your Name*"
COM_SPPAGEBUILDER_ADDON_AJAX_CONTACT_PH_NUMBER="Phone Number*"
COM_SPPAGEBUILDER_ADDON_AJAX_CONTACT_PH_DATE="Select Date*"
COM_SPPAGEBUILDER_ADDON_AJAX_CONTACT_PH_TIME="Select Time*"
COM_SPPAGEBUILDER_ADDON_AJAX_CONTACT_PH_EMAIL="Email Address"
COM_SPPAGEBUILDER_ADDON_APPNT_FORM_CAPTCHA="Captcha Question"
COM_SPPAGEBUILDER_ADDON_AJAX_CONTACT_PH_MESSAGE="Your Message"
COM_SPPAGEBUILDER_ADDON_APPNT_FORM_SEND="Get Appointment"
COM_SPPAGEBUILDER_ADDON_APPNT_FORM_SUCCESS="Request submitted successfully!"
COM_SPPAGEBUILDER_ADDON_APPNT_FORM_CHOOSE_CATEGORY="Choose any category"
COM_SPPAGEBUILDER_ADDON_APPNT_FORM_CHOOSE_PACKAGE="Choose any package"
COM_SPPAGEBUILDER_ADDON_AJAX_APPNT_PACKAGE="Package"
COM_SPPAGEBUILDER_ADDON_AJAX_APPNT_NAME="Customer Name"
COM_SPPAGEBUILDER_ADDON_AJAX_APPNT_CATEGORY="Category"
COM_SPPAGEBUILDER_ADDON_AJAX_APPNT_PHONE_NO="Number"
COM_SPPAGEBUILDER_ADDON_AJAX_APPNT_DATE="Date"
COM_SPPAGEBUILDER_ADDON_AJAX_APPNT_TIME="Time"
 

Then, after translation, you have to change the filename
from: en-GB.tpl_shaper_salon.ini
to: xx-XX.tpl_shaper_salon.ini

Where xx-XX is a LANG-PREFIX, for example, es-ES – for Spanish (Español). Once the phrases inside file have been translated and file renamed, you can copy your language file into your "native" language directory using an FTP client.

You can also translate selected phrases using Joomla Language Override system.
