is there any way to make Custom Own regular expression for email, like i want to go with abc@xyz.com instead of abc@gmail.com.?

Question

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

Actually I want to create one registration form in php 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.

Answer 1

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

Here's a regex-tester

Answer 2

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
}

Answer 3

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

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