RE: [PHP] php varible in Javascript alert()

[Chrome]

Your example will earn you a { missing ; before statement } error from the
JS interpreter... Though it will work if you add quotes:





var errorMsg = '<?php echo addslashes($phpError) ?>';
alert('error found: ' + errorMsg);



Also I removed the $ prefixing the JS vars... It's not necessary :)

PS Thinking on it why not just:



alert('error found: <?php echo addslashes($phpError) ?>');

Alert isn't a native PHP command so:



wouldn't work... This might though:

alert(\'' .
addslashes($string) . '\');  '; ?>
?>

I think the line breaks may go a bit wonky :|

RE: [PHP] php varible in Javascript alert()

[Chrome]

Does $errorMessage have any single quotes in it? Eg:

Can't connect to DB

Because if it does it will cause a Javascript error:

alert('Can't connect to DB');

Just another thing to look for :)

Hi,

I am not sure why this won't work I am pretty sure I have done it before;

if($error)
{
  echo $errorMessage;  // for testing error message is displayed to screen
  echo"alert('$errorMessage');";
}

I am capturing all the errors from a form and then output them all at once

Thanks for any help

Or perhaps more effectively:

alert('');

...or to tweak the OP's own syntax, adding curly braces to make sure 
PHP is parsing the variable properly:


echo "type=\"text/javascript\">alert('${errorMessage}');";


Mace, what value of $error are you testing?  Is the first plain echo 
line executing?  If it is, I suspect it's the curly braces you've 
been missing (although I can't say why; the single-quotes should 
provide sufficient delimiters for PHP).


Tangentially, I'd like to mention that if your error message appears 
in an alert but nowhere else, then after the user makes the alert go 
away (which they might do with an errant keystroke before reading it 
properly) the message can't be recalled.  I recommend doing for the 
user almost exactly what you're doing for debugging purposes -- 
output the error message to the page AND to a javascript 
alert().  The alert() gets their attention, and the page-bound error 
message lets them read it again.


if($error)
{
echo <<< hdErrmsg
$errorMessage
alert('${errorMessage'});
hdErrmsg;
}
