hi,

i have passed following parameters in ajax function,

onclick = "agU(<?php echo $u . ' , ' . $msg; ?>);"
its not working. when i test the same function in following way it runs fine.

onclick = "agU(<?php echo $u; ?>);"
am i commiting any mistake in supplying variable???
please help..

You need to 'quote' your vars:

onclick = "agU('<?=$u;?>','<?=$msg;?>');"
I've used 'short tags' above - which is frowned upon [PLEEZE no more self-righteous 'I disagrees'!! IDGAD], but you can swap these for the full <?php echo $u;?> and <?php echo $msg;?> if you want.

You could also build a complete parameter string in pHp first (including quote marks) and then just include the php string - without encompassing quote marks.

From what I can see, your problem was quote marks - or should I say, the lack of them.
