Is there any way to make Custom own email regular expression?

Actually I want to create one registration form in p.h.p. and for email validation,

I want to make my own customized email regular expression. For example,lets say I want to check that the given mail is name-number@ves.ac.in.

It should only accept email id that ends with ves.ac.in and should notify if given mail is not matching with expression. I did lot of experiment on:

^([a-zA-Z0-9_\-\.]+)@([a-zA-Z0-9_\-\.]+)\.([a-zA-Z]{2,5})$

but this expression but failed. please help.

  • The regex that you show appears to (try to) validate generic email addresses, it doesn't restrict to `ves.ac.in`. You want to start with something like `^([a-zA-Z0-9_\-\.]+)@ves\.ac\.in$`. – nnnnnn Dec 07 '16 at 06:20

The right regex could be this: ^([a-zA-Z0-9_\-\.]+)@ves\.ac\.in$

if you are validating with jQuery or javascript, then you can validate using 

var filter=/^([\w-]+(?:\.[\w-]+)*)@((?:[\w-]+\.)*\w[\w-]{0,66})\.([a-z]{2,6}(?:\.[a-z]{2})?)$/i;
if(!filter.test(email)){
 // add error here
}

To check for a particular domain e.g, (yahoo.com):

 regx =  /^[^@\s]+@yahoo\.com$/i;
 regx.test(input);
 //returns true if it matches

  • you can put your own domain. – Raki Dec 07 '16 at 11:40
  • I didn't point out about any domain. the `dot` in your regular expression matches any character not a literal `.` you should escape it like `^[^@\s]+@yahoo\.com$` – bansi Dec 07 '16 at 11:43
