How do I mix PHP and JavaScript OR how can I do the following PHP and exclude JS?

wheeler08

The JavaScript code is this:
document.check_avail.month.value=mn;

What is the PHP code (to match above), that will call a specific value, in a list on an HTML page?

Secondly, how do I mix PHP and JavaScript? Here is a sample of what I am trying to do:

<?
$month=8;
?>

Hi Wheeler,

Please remember: PhP code is "executed"on the server, and never ever gets to the browser (Unless there is a server error ..). So mixing PhP & javascript.. Nope. They work on different locations

this should work for the simple example you want to do anyway

<? 
$month = 8;
echo "<script language=\"javascript\">\n";
echo "document.check_avail.month.value = " . $month . ";\n";
echo "</script>\n";
?>

Or even simpler:

<script language="javascript"> 
document.check_avail.month.value = <? echo $month ?> ; 
</script>

The only thing that was missing in the PHP snipet within the Jscript was that you forgot the echo function -- just typing a variable identifier is useless.

The reason you had the error is that, because the PHP snipet was not outputing anything within the Jscript. So the Jscript saw it as:

document.check_avail.month.value = ;

Which, as you now know, will cause an error.

yes, your way will do it also, but i had a feeling it would be easier for him to understand it if php echo'd it all, since that is the way he is likely doing it, i don't prefer it that way however

btw, fyi, echo is not a function, it is a language construct
