values in form not passed using onclick ?

i have a php file name main.php

i want to do a post and not a get since this action is to delete a row in the database.

however, when i try to do a href onclick, the values are not passed to the main.php.

why ?

echo "You have " .$votesattach. " votes for this quote. Delete the Quote and Votes ?";
echo "<form name=send1 method=post action=main.php?action='deleteit'>";
echo "<input type=hidden name=action value=deleteit>";
echo "<input type=hidden name=which value=$delete>";
echo "<input type=hidden name=userno value=$userno></form>";
echo "<a href=main.php onclick=document.send1.submit()>YES</a>";
}

how do i do pass values to the server using a post method ?

============begin quote===============

echo "You have " .$votesattach. " votes for this quote. Delete the Quote and Votes ?";
echo "<form name=send1 method=post action=main.php?action='deleteit'>";
echo "<input type=hidden name=action value=deleteit>";
echo "<input type=hidden name=which value=$delete>";
echo "<input type=hidden name=userno value=$userno></form>";
echo "<a href=main.php onclick=document.send1.submit()>YES</a>";

================end quote===============

You're trying to use get and post both. Look at the 'action' url in your form tag.
