i want to pass php variable value as a action to html form. i am trying as follows, but it is not working.
<form name="upload" action="<?=$url?>" method="post" >
<input type="submit" value="submit">
Have you tried
<?php echo $url ?>
If it works, then short_open_tag in the php.ini is turned off. That means you will need to either turn it on or use the long open tag
<?php throughout your code.
