echoing a jquery alert popup in php - php

Question

I want to display a pop-up alert box upon some condition in PHP being satisfied. Something like:
echo "<script type="text/javascript"> alert('bleh'); </script>";
except using a custom jquery alert box. Is this possible??
I've tried something like:
echo "<script src="http://code.jquery.com/jquery-1.9.1.js"></script>
<script src="http://code.jquery.com/ui/1.10.3/jquery-ui.js"></script>
<link rel="stylesheet" href="/resources/demos/style.css" />
<script>
$(function() {
$( "#dialog-message" ).dialog({
modal: true,
buttons: {
Ok: function() {
$( this ).dialog( "close" );
}
}
});
});
</script>";
but it gives me a weird effect. Not pop up.
Thanks for your interest.

Try something like this. Where $bleh is the PHP variable with the message to show.
<script type="text/javascript">
$(document).ready(function(){
var dlg = $('<div>').text(<?php echo $bleh ?>);
$(body).append(dlg);
dlg.dialog(
modal: true
);
});
<script>

PHP is expecting " (double quotes) in any lines like rel="stylesheet" to be php code. You have to either use ' (single quotes) or escape them with a function around the echo like add_slashes. To get around this, I generally use single quotes around echo contents, so all the double quotes are not bothered.
echo 'all the "quoted" stuff here';

Answer 4

Yes its possible..
echo "<script type=\"text/javascript\">alert('bleh');</script>";
but i am not sure if its a good way to write whole function in echo, Instead Define Your Function in HTML some where in your Page and echo the function name here like i did above..

Answer 5

as noted before you need to escape your character or use it like this so no need to escape characters in here
<?php if (condition == true) : ?>
<script src="http://code.jquery.com/jquery-1.9.1.js"></script>
<script src="http://code.jquery.com/ui/1.10.3/jquery-ui.js"></script>
<link rel="stylesheet" href="/resources/demos/style.css" />
<script>
$(function() {
$( "#dialog-message" ).dialog({
modal: true,
buttons: {
Ok: function() {
$( this ).dialog( "close" );
}
}
});
});
</script>
<?php endif; ?>

Sure thing. you probably want something around this:
<script src="http://code.jquery.com/jquery-1.9.1.js"></script>
<script src="http://code.jquery.com/ui/1.10.3/jquery-ui.js"></script>
<link rel="stylesheet" href="/resources/demos/style.css" />
//check for PHP condition. Script will only be output on condition pass.
<?php if(condition == true){ ?>
<script>
$(function() {
$("#dialog-message").dialog({
modal: true,
buttons: {
Ok: function() {
$(this).dialog("close");
}
}
});
});
</script>
<?php } ?>
basically, you don't actually need to 'echo' the script, as long as you're outputting it from a .php file and not an external .js file. the script will show up as long as the condition passes.
