[RESOLVED] PHP echo embedded in HTML vs actual string

[johanafm]

I'm curious as to why the following does not produce the same results.

Inside smarty template:

{php}
$str = "'" . addcslashes(str_replace(',', '.', var_export($p_data[0], true)), "'") . "'";
$GLOBALS['page']->assign("str", $str);
{/php}

Output value of smarty variable<br>
{$str}

<br><br>
Output value of variable with embedded php<br>
{php} echo $str; {/php}

<br><br>
Direct output<br>
'array ( \'pID\' => \'1\'. \'fName\' => \'John\'. \'lName\' => \'Doe\'. )'

Which displays:
Output value of smarty variable
'array ( \'pID\' => \'1\'. \'fName\' => \'John\'. \'lName\' => \'Doe\'. )'

Output value of variable with embedded php
'array ( \'pID\' => \'1\'. \'fName\' => \'John\'. \'lName\' => \'Doe\'. )'

Direct output
'array ( \'pID\' => \'1\'. \'fName\' => \'John\'. \'lName\' => \'Doe\'. )'

However, while this works (outputs the same as above except for the first and last single quote and with the others no longer escaped),

<select name="hmp" id="hmp" 
onchange="display_stuff('array ( \'pID\' => \'1\'. \'fName\' => \'John\'. \'lName\' => \'Doe\'. )')">

the following alternatives do not (each of them displays nothing)

<select name="hmp" id="hmp"
onchange="display_stuff({php} echo $str;>{/php})"
<select name="hmp" id="hmp" 
nchange="display_stuff({$str})">

So, what am I missing here?

I suddenly got an idea and checked the string lengths which differed. The extra, not printed, characters where all made up of chr(0xa) (CR) and " ". Removing all CRs got it working. While I still don't understand why the existant of a few CRs would break the javascript, that's hardly a matter for this forum.
