javascript - data is not sent to php from ajax -

-

hi
in code below want send email (with input data user, in case email address) php file but

$email = $_post['email']; <<<<<<<<<<<< retrieve nothing in php file

js file

<script type="text/javascript">     $(document).ready(function() {         $("#form").submit(function() {              $.ajax({                  url: "data.php",                  type: "post",                  datatype: "json",                  data: { email: $('#email').val()},                  success: function(data) {                      if () {                          //something                      } else {                          //something                      }                  }              });              return false;          });     }); </script>

any reason that?

<form method="post" id="form" action="">                         <div>                             <label for="name">name</label>                              <input id="name" name="name" type="text" />                              <span id="nameinfo">insira o seu nome</span>                         </div>                         <div>                             <label for="email">e-mail</label>                              <input id="email" name="email" type="text" />                              <span id="emailinfo">insira um email válido por favor!</span>                         </div>                         <div>                             <label for="mypassword">password</label>                              <input id="mypassword" name="mypassword" type="password" />                              <span id="mypasswordinfo">insira pelo menos 4 letras e sem espaços</span>                             <div id="bar" style="width: 234px; height: 20px;"></div>                         </div>                         <div>                             <label for="pass2">confirm password</label>                              <input id="pass2" name="pass2" type="password" />                              <span id="pass2info">confirme password</span>                         </div>                         <div></div>                         <div>                             <input id="send" name="send" type="submit" value="send" />                         </div>

as said (before deleted)

<script type="text/javascript"> $(document).ready(function() {     alert( $('#email').val() );   }); </script>

this doesn't show in alert

your not targeting right form want

 $("#customform").submit(function() { ....

given new information suspect either don't have jquery loaded or did put in inputs

here demo showing data in eamil

php - What is the difference between $_SERVER['PATH_INFO'] and $_SERVER['ORIG_PATH_INFO']? -

-
what’s difference between $_server['path_info'] , $_server['orig_path_info'] ? how use them? when run print_r($_server) , path_info , orig_path_info not present in array. why not? how can enable them? i have read php manual on them, still don’t understand them. the path_info variable present if invoke php script this: http://www.example.com/phpinfo.php/hello_there it's /hello_there part after .php script. if don't invoke url that, there won't $_server["path_info"] environment variable. the porig_ prefix uncommon. path_info standard cgi-environment variable, , should never prefixed. did read that? (there issues around php3/php4 if invoked php interpreter via cgi-bin/ - hardly has such setups today.) for reference: http://www.ietf.org/rfc/rfc3875
