You can then access the variables via $HTTP_POST_VARS instead of $HTTP_GET_VARS. You still cannot have more than one variable by the same name since they will just keep overwriting the values, but you can pass in an array of values. I'm going to assume based on your example that a user is allowed to type in three different site names so you would want something like this. <FORM METHOD="POST" ACTION="your_action"> <INPUT TYPE="TEXT" NAME="site[0]" VALUE=""> <INPUT TYPE="TEXT" NAME="question[0]" VALUE=""> <INPUT TYPE="TEXT" NAME="site[1]" VALUE=""> <INPUT TYPE="TEXT" NAME="question[1]" VALUE=""> <INPUT TYPE="TEXT" NAME="site[1]" VALUE=""> <INPUT TYPE="TEXT" NAME="question[1]" VALUE=""> </FORM> When you post that back to your php script you can use: <? print_r($HTTP_POST_VARS); ?> to see the values. You will have an array at $HTTP_POST_VARS['site'] and $HTTP_POST_VARS['question'] which you can loop through and do what you please with. You can also loop through values and output the form dynamically filling in the values in the brackets as you go. Also, you could so something like this: <FORM METHOD="POST" ACTION="your_action"> <INPUT TYPE="TEXT" NAME="data[][site]" VALUE=""> <INPUT TYPE="TEXT" NAME="data[][question]" VALUE=""> <INPUT TYPE="TEXT" NAME="data[][site]" VALUE=""> <INPUT TYPE="TEXT" NAME="data[][question]" VALUE=""> <INPUT TYPE="TEXT" NAME="data[][site]" VALUE=""> <INPUT TYPE="TEXT" NAME="data[][question]" VALUE=""> </FORM> You will then have an array accessed via $HTTP_POST_VARS['data'][x]. As you can tell this will allow you to easily add as many elements as you would like and simple loop through them. Hope that helps you out. - Jamie
