i'm looking bit of , bit of explanation here.
i have created html form several input fields , basic php validation when posting inputs. validation checks see if field has data , if not, prompts user enter data in field displaying error. hope post these inputs, check them against database, , if aren't there, add them database. but, not issue @ hand.
currently, objective take of inputs in field want post , display them in field below error display area. had hoped echo data reason, not of entered data appears.
of 5 entry fields in code below, 4 basic input fields , 1 text area. if enter basic input fields, last input echo in display area. if enter field 1 , leave rest blank, field 1 display. also, if enter text area, display. finally, php validation not appear work textarea type input (labeled 'note') , not return error if 'note' input left blank.can explain: (1) how fix 5 inputs display in display div?; (2) why happen?; (3) why no error returned if text area (labeled 'note') left blank?
thank you.
