Entonces seria asi:
<? if(isset($my->username)){
echo \"<form name="smiletagform" method="post" action="<?php echo $smiletagURL; ?>post.php" target="iframetag">
Nick<br /><input type="hidden" name="name" value="$my->username;"/>
<br />
Mensaje<br /><textarea name="message_box" rows="2" cols="15"></textarea>
<br />
<input type="hidden" name="message" value="" />
<input type="submit" name="submit" value="Enviar" onclick="clearMessage()" />
<input type="reset" name="reset" value="Borrar" /><br />
</form>\";
}
?>
Con este codigo me da 2 errores:
Warning: Unexpected character in input: '\' (ASCII=92) state=1 in /home2/public_html/modules/mod_smiletag_shoutbox.php on line 74
Parse error: syntax error, unexpected T_STRING, expecting ',' or ';' in /home2/public_html/modules/mod_smiletag_shoutbox.php on line 74
Perdona es que no tengo mucha idea de php
