For EE1.x.x only, though may be adaptable to EE2
Allow for drop-down driven searches by editing the file, core.regex.php
Replace this code segment near the bottom of core.regex.php:
/** ----------------------------------------
/** Clean Keywords - used for searching
/** ----------------------------------------*/
function keyword_clean($str)
{
$str = strtolower($str);
$str = strip_tags($str);
... with this improvement that allows drop-down menu driven searches to exist, such as on this and all other flower detail pages at NCWildflower.org, for example.
/** ----------------------------------------
/** Clean Keywords - used for searching
/** ----------------------------------------*/
function keyword_clean($str)
{
if (is_array($str)) {
$str = implode(' ',$str);
}
$str = strtolower($str);
$str = strip_tags($str);
Here is my own test code snippet modifying the simple search form. Note how it uses name=“keywords[]” - the brackets designate a result that will employ concatenation:
{exp:search:simple_form weblog="plants" search_in="everywhere" where="all"}
<p><label for="keywords">Search:</label><br />
<input type="textarea" name="keywords[]" id="keywords" value="" size="18" maxlength="100" /></p>
<input type="textarea" name="keywords[]" id="keywords" value="" size="18" maxlength="100" /></p>
<p><input type="submit" value="submit" class="submit" /></p>
{/exp:search:simple_form}
And here is the actual code being used to make the search drop-downs work at NCWildflower.org (I implemented it as an embedded template):
{exp:search:simple_form weblog="plants" search_in="everywhere" where="all"}
<p><i>(This mini-search is still an experimental feature - give it a try! <br />For instance, find a plant that already thrives in your garden, and enter some of the same criteria to find others similar. <br />See also our <a href="http://www.ncwildflower.org/natives/recommend.htm">Recommended Plants section!</a>)</i><br /><br /></p>
