regex - Regular Expression for email subdomain match -


Does anyone detect regular expressions that match those emails in which they contain a sub-domain?

For example,

name@subdomain.domain.com or name@subdomain.domain.edu .au

preferably to use.

I tried to do this: 

  ^ [- +. 0-9A-Z-AZ] + @ [- + 0-9A-ZAED] + \. [E-za-z] {2,4} $

but it also matches name @ Test.org .

Do not do anyway for recognition purposes. It will only end in pain.

The only appropriate regular expression to validate an email address that searches for "@" sign and at least one period. Nothing; Even the arrival of alphanumerics does not make any sense.

At the minimum, you need to really define "subdomain". Everything subdomain is a subdomain? What is included and what is included in it?

How do you define "subdomain" by making "top level"? Do you mean "a subdomain"? "Subdomain of a subdomain of a domain that is open for public registration"? At what level of the delegation does it become a subdomain for your purposes?

Regarding the official domain, where "public" which can register the domain is very limited, and the rule of subdomain-of-subdomain is ideal? What do you want to match?

How will you cope with the fact that the list will change over time? Or with the addition of CCTLD / Removal? If CCTL changes its policy, then instead of selling only specific sub-registrars (for example "myname.org.au"), rather than direct descendant domains (eg "do you dynamically update your regex , And if so, how would you handle the valid address address and no longer remain, or vice versa?

I run a stupid email verification system which is my main email address ringerc @ ringerc. Id.au (as long as it's already 'nat' There is no issue till then) despite being a fully valid .id.au domain.

Please make another if your intention is not valid, it is good, but Please do not try to validate the e-mail address domain with a regex.

mongodb - CakePHP paginator ignoring order, but only for certain values -

While pagging my user model in kppp, I can sort with some values, but not others. For example, I can order results from created or email , for example, but username or reputation seems to come back order by arbitrary command for example with a list of users: $ this-> paginate = array ('condition' => array ( 'User.is_active' = & gt; true), 'border' => 24, 'order' => array ('User.created' => DESC)); Works as expected, but $ this - & gt; Paged = array ('conditions' = & gt; array (' user.isIactive '= & gt; true),' border '= & gt; 24,' command '= & gt; array (' user repeats' = ' & Gt; DESC ')); No, no. I first thought that this could be a database issue, but when I search the database directly, sorted as expected. Note: I am using Mangodebi with the Mongo DB plugin of Ichikawa for the KPPHP; Pagnetizing users are used to work properl...
