I have Javascript code that I output inside of a PHP file, but put
variables inside the javascript block. I am getting a weird error:
<?php
function SomeFunction()
{
?>
<script type="text/javascript">
parentValue = <?=$parentValue?>;
</script>
<?
}
?>
I get an error over the '<?' of the '<?=' expresssion in the javascript
block saying: Syntax error on tokens, PostfixExpression expected instead
Anyone know why this is?
Thanks,
Micah

Couple thoughts...
1. Try using fully-formed PHP, not the lazy <?= ?> format.
2. Try wrapping your javascript variable assignment (unless it's an
integer!) with quotes.
Thus:
<?php
function SomeFunction()
{
?>
<script type="text/javascript">
parentValue = '<?php print $parentValue; ?>';
</script>
<?
}
?>
Or, better:
<?php
function SomeFunction()
{
print<<<EOHTML
<script type="text/javascript">
parentValue = '${parentValue}';
</script>
EOHTML; // must be flushed to left margin
}
?>

That didn't make a difference.

They are integers, but it doesn't matter since I'm just passing them to
a PHP script with AJAX. This actually worked, but I have a new problem:
if (parentValue)
{
<?php echo $function;?>
}
gives me these errors:
Multiple annotations found at this line:
- Syntax error on token "<", invalid Expression
- Syntax error on token "?", invalid Expression
- Syntax error on token ">", FullPostfixExpression expected after this
token
- Syntax error on token "echo", : expected
- syntax error, unexpected 'EOF'
It seems like the Javascript parser has trouble with the PHP inside the
javascript, even though the javascript is in a PHP file.

I might have to try this instead.

What is the value of $function?

You might want to open a bug against PDT (or maybe this is a DLTK
issue?) explaining what you've tried and what workarounds (if any) work
to clear the reported errors.
Sounds like there are parser usecases not yet implemented.
Have you tried doing your javascript in a separate file so that it can
be parsed w/ a JS editor, rather than a PHP editor?

The name of a xajax function. This is while editing, not running that I
get the error.

I'll have to do that. I just wanted to make sure that I wasn't missing
a config setting before filing a bug.

I have pure Javascript functions in a separate file, but it happens to
be that 65% of this function is generated from PHP variables, so I am
outputting it inline.
Thanks,
