How to show an alert box in PHP?

Question

I want to display an alert box showing a message with PHP.

Here is my PHP code:

<?php  
  header("Location:form.php");

  echo '<script language="javascript">';
  echo 'alert(message successfully sent)';  //not showing an alert box.
  echo '</script>';
  exit;
?>

But it is not working.

Why do you want header("Location:form.php") at the top? If you want to redirect the user to form.php AFTER the alert, you should just redirect the user in the Javascript as such : echo 'location.href="form.php"'; — ashiina, Dec 12 '12 at 10:39
Look what you have written => echo 'alery(message successfully sent)'; //not showing an alert box. It should be alery not akery. — Pratik Joshi, Mar 10 '14 at 05:01

changed it but still not working. – prakash_d22 Dec 12 '12 at 10:17
@prakash_d22 have you tried to debug it in `firebug` because the code is correct. – Yogesh Suthar Dec 12 '12 at 10:19
Yes I know the code is fine, but I am not getting the alert box.Is it because of header/exit clause? – prakash_d22 Dec 12 '12 at 10:21
@prakash_d22 may be it was causing problem. Try to comment it and try. – Yogesh Suthar Dec 12 '12 at 10:23
yes after commenting its working, but I want both . – prakash_d22 Dec 12 '12 at 10:27
@prakash_d22 if you want alert and exit then move the `header` after alert and after that write `exit` OR you can also redirect using `javascript's` window.location. – Yogesh Suthar Dec 12 '12 at 10:33

Try this:

Define a funciton:

<?php
function phpAlert($msg) {
    echo '<script type="text/javascript">alert("' . $msg . '")</script>';
}
?>

Call it like this:

<?php phpAlert(   "Hello world!\\n\\nPHP has got an Alert Box"   );  ?>

That’s not a syntax error, but a reference error. – Sebastian Simon Oct 09 '15 at 12:17

echo "<script>alert('same message');</script>";

This may help.

echo '<script language="javascript>';

Seems like a simple typo. You're missing a double-quote.

echo '<script language="javascript">';

This should do.

change your output from

 echo '<script language="javascript>';

to

 echo '<script type="text/javascript">';

you forgot double quotes... and use the type tag

When I just run this as a page

<?php
echo '<script language="javascript">';
echo 'alert("message successfully sent")';
echo '</script>';
exit;

it works fine.

What version of PHP are you running?

Could you try echoing something else after: $testObject->split_for_sms($Chat);

Maybe it doesn't get to that part of the code? You could also try these with the other function calls to check where your program stops/is getting to.

Hope you get a bit further with this.

this code worked for me echo (""); – prakash_d22 Dec 12 '12 at 10:40
So you're echoing the whole string as a whole. Does your whole page + function calls run okay now? – CE_REAL Dec 12 '12 at 10:42
yes thanks everyone for help.. – prakash_d22 Dec 13 '12 at 12:14

I don't know about php but i belive the problem is from this :

enter code here
echo '<script language="javascript>';
echo 'alery("message successfully sent")';
echo '</script>';

Try to change this with :

echo '<script language="javascript">';
echo 'alert("message successfully sent")';
echo '</script>';

Try to change this with :

  echo
  "<script>
  alert('Sent Successfully');
  document.location.href = 'index.php';
  </script>
  ";
