Instructions

When adding translatable strings to the plugin:

  1. Use the correct text domain: 'retrologin'
  2. Choose the right function:
    • __() - Return translated string
    • _e() - Echo translated string
    • esc_html__() - Return escaped translated string
    • esc_html_e() - Echo escaped translated string
    • esc_attr__() - Return escaped for HTML attributes
  3. Generate POT file: composer run make-pot
  4. Keep strings in English (US)

Translation Functions

__($text, $domain)ReturnStrings in PHP variables
_e($text, $domain)EchoDirect output
esc_html__($text, $domain)Return + escapeDisplaying user content
esc_html_e($text, $domain)Echo + escapeDirect output of user content
esc_attr__($text, $domain)Return + escapeHTML attributes

esc_attr__('Username', 'retrologin');

// In attributes
<input placeholder="<?php esc_attr_e('Enter username', 'retrologin'); ?>">

  • Use escaping functions for user-generated content
  • Keep strings concise for translation
  • Avoid embedding variables in translatable strings
