php - isset($_Post) not getting values from Mail Form -

so i'm trying send values contact form (contact.php) file send_form_email.php. reason i'm not getting values contact.php. i'd appreciate help!

here's form code contact.php file:

<form role="form" id="contactform" name="contactform" enctype='multipart/form-data' method="post" action="send_form_email.php">      <div class="form-group">        <label for="inputfname" style="color: #ecc444; text-shadow: 2px 2px #414141;">first name:</label>        <input type="text" class="form-control" id="inputfname" placeholder="enter first name" maxlength="50" size="30">      </div>       <div class="form-group">        <label for="inputlname" style="color: #ecc444; text-shadow: 2px 2px #414141;">last name:</label>        <input type="text" class="form-control" id="inputlname" placeholder="enter last name" maxlength="50" size="30">      </div>       <div class="form-group">        <label for="inputemail" style="color: #ecc444; text-shadow: 2px 2px #414141;">email address:</label>        <input type="text" class="form-control" id="inputemail" placeholder="enter email" maxlength="80" size="30">      </div>      <div class="form-group">        <label for="inputcomments" style="color: #ecc444; text-shadow: 2px 2px #414141;">comments:</label>        <textarea class="form-control"name="inputcomments" rows="3" maxlength="1000" cols="25" rows="6"></textarea>      </div>      <?php        require_once('recaptchalib.php');        $publickey = "<public-key>";         echo recaptcha_get_html($publickey);      ?>   <br/>   <button type="button" class="btn btn-default" onclick="sendemail()">submit</button> </form> 

upon clicking submit button following javascript function called:

<script language="javascript">     function sendemail() {       document.forms["contactform"].submit();     }  </script> 

this submits form , calls file send_form_email.php:

<?php session_start(); require_once('recaptchalib.php');   $privatekey = "privatekey";   $resp = recaptcha_check_answer ($privatekey,                                 $_server["remote_addr"],                                 $_post["recaptcha_challenge_field"],                                 $_post["recaptcha_response_field"]);    if (!$resp->is_valid) {     // happens when captcha entered incorrectly     die ("the recaptcha wasn't entered correctly. go , try again." .

i have left out values such public/private key recaptcha , email obvious reasons.

i can't figure out i'm doing wrong.

thanks guys.

all of form fields missing name attribute. without values not sent server.

for example:

<input type="text" class="form-control" id="inputfname" placeholder="enter first name" maxlength="50" size="30"> 

is missing name="inputfname":

<input type="text" name="inputfname" class="form-control" id="inputfname" placeholder="enter first name" maxlength="50" size="30">
