why is my echo '<script>alert("Cannot be deleted!")</script>'; is not working?

phpbigenner · July 11, 2013

<?php

$act = $rs['actorID'];

$m=mysql_query("SELECT * FROM movie_actor where actorID = '$act'");

$ma = mysql_num_rows($m);

if($ma!=0){

echo '<script>alert("Cannot be deleted!")</script>';

}else{

echo '<td style="text-align:center"><a href="delete_actor.php?ID='.$row['actorID'].'" onclick="confirmation();return false"> <img height="40" width="40" src="icons/xx.png" /></a>

</td> ';

}

?>

Does <script>alert("Cannot be deleted!")</script> actually get echoed if you view the page source after the page loads? If it is there, what doctype are you using? I am no pro javascript guy by any stretch of the meaning but I believe that in most doctypes besides html5 you need to specifiy type="text/javascript" in the <script>, not sure if not having that will make it not work but worth a try.

Try putting in a <meta name="content-script-type" content="text/javascript"> in your head section before the scripts, otherwise do as fastsol said.

my whole code now.

Maq · July 11, 2013

Please use code tags in the future.

fastsol · July 12, 2013

I don't see anything that stands out as an issue in your code. Again, are you sure that <script> tags are actually being echoed to the page? Run your page in the browser and then do a view page source and see if they are in there. You could also post the view source result here and we can take a look.

phpbigenner · July 12, 2013

the script didn't echoed.

Use

tags when posting code.

fastsol · July 12, 2013

the script didn't echoed.

Well there ya go, you need to figure out why it's not echoing the tag. You have something wrong in your php logic.

phpbigenner · July 12, 2013

okay. i'll try to figured it out.

phpbigenner · July 12, 2013

I got it men. thankyou. @ fastsol

fastsol · July 12, 2013

Glad you got it working! You just have to remember to start with the baiscs of diagnostics to figure out a problem.
