原文外掛簡介
Add an international country code dropdown with flags to any Elementor Pro form phone field. Searchable list, WPML-aware error messages, E.164 output, and per-country validation — without the duplicate submissions, broken multi-step navigation, and identical flags that affect similar plugins.
Country Code Field Features for Elementor
Country dropdown on any Tel field — no new widget, just extra controls inside the existing form field settings.
Auto-localised error messages — validation strings are translatable via WPML String Translation, Polylang, Loco Translate, or a .po/.mo file.
Cache-plugin safe flags — the selected flag is painted via an inline style pointing to an individual SVG, so WP-Rocket’s “Remove Unused CSS” and LiteSpeed’s CSS minifier can’t turn every country’s flag into the same one.
No duplicate submissions — unlike the common reference implementation, this plugin never calls handleSubmit or setTimeout. It keeps the input’s E.164 value fresh and lets Elementor’s native submit handler run untouched.
Safe pre-fill — if the field is pre-populated with an E.164 value (cookie, autofill, URL param), the country dial code is not duplicated.
Auto-detect visitor country — uses the browser’s language, no external API call.
Preferred / Only / Exclude country lists — customize which countries appear in the dropdown.
Multi-step form compatible — does not interfere with Elementor’s step navigation.
Strict validation (optional) — blocks submission if the number fails intl-tel-input validation.
Server-side sanity check — digits + length bounds enforced in elementor_pro/forms/validation/tel.
Requirements
WordPress 6.0+
PHP 7.4+
Elementor + Elementor Pro (the Form widget is an Elementor Pro feature)
Compatibility & Use Cases
Tested compatibility:
Elementor Pro — works with the Pro Form widget; the country-code controls appear inside the existing Tel field settings, so there’s no new widget to learn.
WPML & Polylang — the country-list locale is resolved from the active language, and every validation error string is registered with both string-translation registries.
Cache plugins — WP-Rocket, LiteSpeed Cache, W3 Total Cache, and Autoptimize won’t break the flags. Per-country SVGs are painted via inline style attributes that no CSS minifier can prune.
Multi-step forms — the plugin never wraps Elementor’s submit handler, so multi-step navigation (Next / Previous) stays intact.
Privacy & performance:
GDPR-friendly — no external API calls. Auto-detect uses navigator.language (a local browser hint), not an IP lookup or third-party geo-service.
Lightweight — the intl-tel-input library, CSS, and country-code script are enqueued only on pages where an Elementor form with the country-code feature is actually rendered. Other pages are completely untouched, so PageSpeed and Core Web Vitals scores on the rest of your site are unaffected.
Common use cases:
Contact forms with a phone field
Registration and onboarding forms
Lead-generation and quote-request forms
Booking and appointment forms
WhatsApp click-to-chat and SMS callback forms — the E.164 output (+919876543210) is ready to drop into a wa.me/
