is there a way to check if all form fields are filled in? i can do it singular but just need to know if it can be done

i have a form validation method that i learned already....i cant find if its possible to validate a form as a whole rather than checking if a field is filled out?Comment

Yes, you can. Check the links in the Offsite Links sticky. The basic idea is to validate all the elements of the form one by one onsubmit:
Code:<form ... onsubmit="return validate()">

i think im going about this the wrong way.....is it possible for javascript to do this i.e. say if the form returns no errors then do something else?Comment

ok ive done the validation..... is there a way i can get a value thats in javascript into a php.....i want to get the value that goes into obj2 into a php var......is it possible?
Code:<script> function CopyValue(obj1, obj2) { var visibleField = obj1; obj2.value = visibleField.value; } </script>Comment

Yes, either pass it through the URL:
or set a hidden field value in the form to the variable value:Code:location.href="file.php?var="+encodeURIComponent(jsvar);
Note:encodeURIC omponent() encodes the value in case there are any special characters.Code:document.getElementById("hidden").value = jsvar;Comment

does this do so without having to go to another page or refresh?Comment

Yes, but if you want to avoid that, use Ajax.Comment
