 * Aufgerufen wird die Formularüberprüfung mit checkForm(form_name,lang,editorArray)
 * Die Felder werden gemäss alt Attribut geprüft r = required, d = datum, e = email, n = nummer
 * Ausnahme sind Textfelder und Selects, dort muss in der id  _r stehen, damit sie überprüft werden
 * HTML Editor wird in Textaera geschrieben
 * Called is the form checking with checkForm(form_name,lang,editorArray)
 * The fields are check accoring to there alt attributes r = required, d = date, e = email, n = number
 * Execptions are textareas and selects, there the id must contain _r, that they are checked
 * phpEditor is written into textarea
