This section is for Introductions! ('introduce yourself')

:code:

and be more polite instead of 'PLEASE TELL HOW TO SOLVE THE ERROR FOR THE FOLLOWING CODE'

I made a few changes to your code and I think now it is ok!

First of all, I introduced a new variable called $sql just to make the code more readable.
I changed the syntax a bit to overcome the error. See line 8.

Moreover, I used the function mysql_num_rows($result1) to check if something was returned from the database.

I would strongly recommend to check any data coming from the user before querying the database using them.

<?php
$message = "";
   if(isset($_REQUEST['submit']))
     {
       $connect=mysql_connect("localhost","root","");
       mysql_select_db("regis",$connect);
       
      $sql = "SELECT email FROM regist WHERE email='" . $_POST['mailid'] . "' AND password='" . $_POST['pwd'] . "'";
      $result1 = mysql_query($sql);
      //$result1=mysql_query("SELECT email,password FROM regist WHERE email='$_POST['mailid']' and password='$_POST['pwd']' ");//<br>
      //$result2=mysql_query("SELECT  FROM regist WHERE ");
      if(mysql_num_rows($result1) == 1))
         {
            $message =  "YOU HAVE SUCCESSFULY LOG IN!";
         }
       else
         {
           $message =  "YOU ENTERED WRONG EMAIL/PASSWORD!, PLEASE TRY AGIAN!";
          }
      }
?>
<html>
<body bgcolor="#33CCCC">
<br> <h1 align="center"><b>SIGNIN</b></h1>
<form action="www.google.com" method="post"><br>
<table width="100%" border="0" cellspacing="0" cellpadding="0">
  <tr>
    <th scope="row">EMAIL&nbsp;</th>
    <td>:&nbsp;</td>
    <td><input name="mailid" type="text" />&nbsp;</td>
  </tr>
  <tr>
    <th scope="row">PASSWORD&nbsp;</th>
    <td>:&nbsp;</td>
    <td><input name="pwd" type="text" />&nbsp;</td>
  </tr>
  <tr>
    <th scope="row">&nbsp;</th>
    <td>&nbsp;</td>
    <td><input name="submit" type="submit"/>&nbsp;</td>
  </tr>
</table>
</form>
<?php
  echo $message;
  ?>
  </body>
  </html>

Thanks for trying, but you really failed to improve anything.

Look up SQL Injection, for starters, then go read the documentation and notice that the mysql_* functions should no longer be used, instead using PDO or the mysqli (MySQL Improved) extension.

Well, I know all these things but here the problem wasn't that and I didn't have the time to fully rewrite the code.
