echo php javascript alert?

rated 0 times [ 10] [ 7] / answers: 1 / hits: 15747 / 11 Years ago, tue, november 5, 2013, 12:00:00

How can I echo this javascript if the php error messages is called? I have an error message setting that when a user misses his username or password it triggers an error message. The php error message is called by a php code. Here is the code:

<?php echo showmessage($msg) ?>

I have an alert message in javascript that when called it will make a javascript css pop up alert box. IF the javascript code is present it will show the alert box right away after reload. Here is code:

<script type=text/javascript>  

  $(document).ready(function () {  

   jqxAlert.alert('Alert Message');  

  })  

</script>

How can I incorporate so that when the php echo message comes up it will trigger the javscript alert message. I was trying an if in php, so something like this code:

if ( showmessage($msg) ) {

   <script type=text/javascript>  

     $(document).ready(function () {  

         jqxAlert.alert('Alert Message');  

     })  

   </script>

}

How can I echo my javascript message on the php call?

This could be written like this:

endif

endif-stackoverflow

<?php if (showmessage($msg)): ?>

    <script>

        $(document).ready(function (){

            jqxAlert.alert('Alert Message');

        });

    </script> 

<?php endif; ?>

Or like this:

<?php if (showmessage($msg)) { ?>

    <script>

        $(document).ready(function (){

            jqxAlert.alert('Alert Message');

        });

    </script> 

<?php } ?>

Or like this:

<?php 



    if (showmessage($msg)) { 

        echo

        '

            <script>

                $(document).ready(function (){

                    jqxAlert.alert('Alert Message');

                });

            </script> 

        ';

    } 



?>

short tags

short hand comparison (ternary)

ternary 2

Or even this (probably not the best idea though):

<?= (showmessage($msg)) ? '<script>$(document).ready(function (){jqxAlert.alert('Alert Message');});</script>' : ; ?>

Alternatively, if you mean you would like to put the error message in that alertbox

<?php 



    if (showmessage($msg)) { 

        echo

        '

            <script>

                $(document).ready(function (){

                    jqxAlert.alert('.showmessage($msg).');

                });

            </script> 

        ';

    } 



?>

and again in the first style:

<?php if (showmessage($msg)): ?>

    <script>

        $(document).ready(function (){

            jqxAlert.alert(<?= showmessage($msg) ?>);

        });

    </script> 

<?php endif; ?>
