i'm looking way redirect after submit depending on echo , used following code:

<?php $to = "mymail@gmail.com"; $name = trim(stripslashes($_post['name'])); $email = trim(stripslashes($_post['email'])); $message = trim(stripslashes($_post['message'])); $subject = "new client call";  $body = 'name: ' .$name."\r\n"; $body = 'email: ' .$email."\r\n"; $body = 'message: ' .$message."\r\n";  $go = mail($to, $subject, $body, "from:<$email>"); if ($go) {     echo "success"; }  else {     echo "error"; } ?>  <form action="index9.html" method="post" name="redirect" ></form> <script> document.forms['redirect'].submit()</script>

but have 2 problems:

  1. i getting "success" echo. client sending empty details.
  2. i want redirect error page javascript (if/else) , don't how.

btw new in field so: appreciate advise/help , thankful.

you don't need javascript achive can use pure php. can use error checking if field empty in form follows

validate.php

if(isset($_post['submit'])){ if (empty($_post["email"])) {     $emailerr = "email required";         } else {             $email = test_input($_post["email"]);             // check if e-mail address well-formed             if (!filter_var($email, filter_validate_email)) {                  $emailerr = "invalid email format";              }      } if (empty($_post["name"])) {             $nameerr = "name required";         } else {             $name = test_input($_post["name"]); }  if (isset( $nameerr) ||  isset($emailerr){      // have error     }  else {     $to = "mymail@gmail.com";     $name = trim(stripslashes($_post['name']));     $email = trim(stripslashes($_post['email']));     $message = trim(stripslashes($_post['message']));     $subject = "new client call";     ....

this check if "email" field empty if promp error "email required"

and in html add error

<form class="form-horizontal" action="validate.php" method="post">      <label for="email">email: </label>      <input type="text" class="form-control input-sm" name="email">      <span class="error">* <br><?php echo $emailerr;?></span>      <input class="btn btn-info btn-lg" type="submit" name="submit" value="submit">      </form>

hope helps
