validate form

[skyloon]

how to validate a form?
it will check whether it is empty or not, if yes, it will ask user to enter the value, the value for name can't in the numeric form, the IC Number can't in the string form. it also check the email is in the correct format.
thank you

To make this sort of validation to work in all sort of browsers I would recommend reading a bit about regular expressions and use ereg() og eregi() to check the content of each form-field. This is in my opinion the best way to check form fields, and allthough it can seem a bit tough to learn at first it isn't really that hard. Try reading this: http://cyrus.stud.hive.no/pdf/Basic_Syntax_Regular_Expressions.pdf for an introduction to the subject.

There is also a great deal of posts conserning the subject on this board, so you can find good information and tips/examples by searching the forum for validation or something like that.

To check if a field is empty, you can simple use:

if($fieldname && $another_fieldname)
   //returns true if the fields above have content
  // and false otherwise

Hope this can help...
