Hola a todos. Bueno pues tengo un problema con este formulario. No quiere funcionar. Supuestamente debes de rellenar todos los campos con un *, sino debería devolverte con una franja roja los campos que no has rellenado. Pero nada no quiere ir. La cosa me esta trayendo de cabeza por que no consigo ver el error.
La verdad es que estoy aprendiendo PHP y no se ya que hacer. Si lo ejecutas, solo falla los campos de Firstname, Lastname, Yourgender. Los campos de password y el texto que hay debajo de Membership Form si funcionan. Sale resaltados de color si no rellenan.
Y si rellenas todos los campos si se envía el formulario.
Osea el fallo esta en: Firstname, Lastname, Yourgender. Debe ser que el codigo esta mal construido. Algo que no se, seguro. Os dejo el script a ver si me podeis ayudar:
