Help MyBB | Form Value Dateline

[c.widow 123]

Currently using a search customization by Shinka (or Shin) and trying to add in a dateline option for date cut off. Unsure of where to go now as I've tried everything I can think of and still get no where.

<form method="post" action="search.php?action=do_search">
	<input type="hidden" name="threadprefix[]" value="1" />
	<input type="hidden" name="findthreadst" value="2" />
	<input type="hidden" name="numreplies" value="3" />
	<input type="hidden" name="showresults" value="threads" />
	<input type="hidden" name="sortby" value="lastpost" />
	<input type="submit" class="button" name="submit" value="Open Threads" />
</form>

I am trying to add in

<input type="hidden" name="postdate" value="30" />

In reference to this in the search template

<select name="postdate">
<option value="0">{$lang->find_anydate}</option>
<option value="1">{$lang->find_yesterday}</option>
<option value="7">{$lang->find_lastweek}</option>
<option value="14">{$lang->find_2weeks}</option>
<option value="30">{$lang->find_month}</option>
<option value="90">{$lang->find_3months}</option>
<option value="180">{$lang->find_6months}</option>
<option value="365">{$lang->find_year}</option>
</select>

Value = 30 being a month back or newer (not older).

 

I'm just... struggling. Help would be lovely. ❤️

Are these two fields in the same form?
