Bauleitung-Formular: contact_form wird Salesforce-Web-to-Lead-fähig, Tracking inklusive

// Webform-Key => SF-Web-to-Lead-Parametername.
// Sprechende Namen bis die 00N…-IDs der SC_*-Felder
// vorliegen (Anfrage Fr. Baur) — dann NUR Werte tauschen.
private const TRACKING_FIELDS = [
  'utm_source'         => 'utm_source',   // → 00N…
  'utm_medium'         => 'utm_medium',
  'utm_campaign'       => 'utm_campaign',
  'utm_term'           => 'utm_term',
  'utm_content'        => 'utm_content',
  'gclid'              => 'gclid',

// map(): Lead-Quelle-Konstanten + 00NSZ00000Ju6Hm/J4
// ersatzlos entfernen; TRACKING_FIELDS anhängen,
// leere Werte auslassen.

// 1) Storage nach Referenz-Script v2:
//    setLocal(utm_*, gclid, msclkid) bei URL-Treffer,
//    setLocalOnce(first_landing_page, first_referrer),
//    setSessionOnce(landing_page), setSession(referrer, page_url)

// 2) Hidden-Felder befüllen — nur mit UC-Consent
//    („Salesforce Marketing Cloud", Muster salesforce-consent.js):
function fillHiddenFields(form, data) {
  Object.entries(data).forEach(([key, value]) => {
    const input = form.querySelector(
      'input[name="' + key + '"]');
    if (input && value) input.value = value;
  });
}

// 3) lead_submit auf der Bestätigungsansicht:
//    PHP liefert drupalSettings.solcomSeo.leadSubmit
//    (email_type, sha256_email_address, form_location) —
//    E-Mail-Normalisierung + Hash serverseitig, nie Klartext.
