Personally I would do as you suggest in 1. I would think your users would
get rather annoyed if they had gone through several form pages to be told at
the end of an error in form page1.
So, page2 validates page1 etc. I would assume that page2 already does some
processing of page1 anyway, as I believe you are adding the form values to
the session. You may want to think along the lines of adding to a string
variable for each validation exception and then passing that back to page1
which will display the string variable if it contains anything. If you want
the originally entered data to also appear in the form fields you will also
have to pass that data back to page1 and display it.
//This is pseudo code ;)
$str='<ul>';
Check form_field1
If (error)
$str .= '<li>Field1 in error</li>';
Check form_field2
If (error)
$str .= '<li>Field2 in error</li>';
$str .= "</ul>";
If (any errors found) {
$location = "page1.php?err=$str&fld1=$field1.....";
Header($location);}
else{
// Store form values in session & continue
}
