passing an array via GET and a hidden form element

I'm trying to pass a variable from a search page to the results page via GET. The $MANUFACTURERS variable contains an array and is obtained from the URL. I've tried the following to no avail... <input name="manufacturer[]" type="hidden" multiple id="manufacturer[]" value=<?php $manufacturer ?>> <input name="manufacturer[]" type="hidden" multiple id="manufacturer[]" value=<?php echo $manufacturer ?>> <input name="manufacturer[]" type="hidden" multiple id="manufacturer[]" value="<?php $manufacturer ?>"> <input name="manufacturer[]" type="hidden" multiple id="manufacturer[]" value="$manufacturer"> <input name="manufacturer[]" type="hidden" multiple id="manufacturer[]" value=$manufacturer> Except for the last two entries, in the URL, the others all passed "...&manufacturer%5B%5D=Array..." When analyzing the variable on the results page, I wind up with $manufacturer equaling an array with one element equaling "Array"... Array ( [0] => Array ) Any suggestions?
