php - $_GET['email'] did not include the '@' character? -

i made custom form forget password in wp.

below code use:

 <form name="lostpasswordform" id="lostpasswordform" action="'.wp_lostpassword_url().'" method="post">  <label for="user_login">username:<br>  <input name="user_login" id="user_login" class="input" value="" size="" type="text"></label><br><br>  <label for="user_email">e-mail address:<br>  <input name="user_email" id="user_email" class="input" value="" size="" type="text"></label>  <input type="hidden" name="" id="url_temp" value="'.str_replace( '%7e', '~', $_server['request_uri']).'&axcelerate=forgotpassword">  <input name="redirect_to" value="&user_login=&user_email=" type="hidden" id="lostpasswordform_addon"><br><br>  <p class="submit">  <input name="wp-submit" id="wp-submit" class="button button-primary button-large" value="get new password" type="submit">  </p>  </form>  <script> jquery('#lostpasswordform #user_login').blur(function() {         jquery('#lostpasswordform_addon').val( jquery('#url_temp').val() + '&user_login=' + jquery(this).val() + '&user_email=' + jquery('#lostpasswordform #user_email').val());     });      jquery('#lostpasswordform #user_email').blur(function() {         jquery('#lostpasswordform_addon').val( jquery('#url_temp').val() + '&user_login=' + jquery('#lostpasswordform #user_login').val() + '&user_email=' + jquery(this).val());     }); </script> 

i have problem in email value when check redirect_to email format correct eg. nameof@mail.com

but when try set in function suing code:

if($_get['axcelerate'] == 'forgotpassword'){             echo $_get['user_email']; } 

it returns nameofmail.com , not nameof@mail.com ?

does have idea case?
