javascript - Can I use conditioned alert in php which is encoded in .html -


i developing page in on adding field data on page want alert putting alert msg in php code .i want alert in html page. have put alert message in php tag not working.

<!doctype html> <html> <body>     <? if(isset($_get['succ'])) {         $message1 = "name correct";         echo "<script type='text/javascript'>alert('$message');</script>";     }     if(isset($_get['err'])) {         $message2 = "name not saurabh";         echo "<script type='text/javascript'>alert('$message');</script>";     }     <form action="action.php" method="post">         first name:<br>         <input type="text" name="firstname">         <br>         last name:<br>         <input type="text" name="lastname">         <br><br>         <input type="submit" value="submit">     </form>      <p>if click "submit" button, form-data sent page</p>  </body> </html>

you need use $message1 or $message2 instead of using $message.

also, need close php tags before opening html element(form in case).

let page url has succ or err in url parameter.

<?php     if(isset($_get['succ'])){         $message1 = "name correct";         echo "<script type='text/javascript'>alert('".$message1."');</script>";// use $message1 not $message     } else if(isset($_get['err'])){ // adding else, url contains succ or err         $message2 = "name not saurabh";         echo "<script type='text/javascript'>alert('".$message2."');</script>";// use $message2 not $message     } ?> <form .....  ....  ....
