hie there... i have this PHP code below. Instead of prompting the error message in next page, i want to prompt in an error box. how do i do this? Thanks.

PHP Code:

if($imageinfo['mime'] != 'image/gif' && $imageinfo['mime'] != 'image/jpeg') 

{

    echo "Sorry, we only allow uploading GIF images";

    exit;

}

PHP is a server side language, it can't do alert messages on the client side. But you can use javascript within the php to do the alert.

Code:

<script type="text/javascript">
window.alert("You message goes here!")
</script>

you cant have alert boxes in server side scripting. you have to use javascript in that case.

i am not sure if you are talking about 'flash pages' like mozilla addons website.

i dont think my term was correct.
flash page = pages showing you a custom message for 3-5 seconds and then redirecting you to another page.

as bizzar528 and Fahad_1 told you "PHP is a server side language, it can't do alert messages"

You can use the below code to generate a alert message

PHP Code:

if($imageinfo['mime'] != 'image/gif' && $imageinfo['mime'] != 'image/jpeg') 

{

    echo "<script type="text/javascript">window.alert("Sorry, we only allow uploading GIF images")</script>";

    exit;

}
