我正在为一个项目使用模板（不幸的是客户的想法），这个模板有一个下拉搜索部分供用户搜索自定义帖子（属性）。唯一的问题是，没有关键字框供用户按关键字搜索。
我正在尝试为用户集成一个搜索功能，以通过关键字进行搜索，但是事实证明这比我最初想象的要困难得多。我不是最精通wordpress（我使用EE）。
有人可以帮我将关键字搜索功能集成到以下代码中：
customsearchform.php
<form id="search" action="<?php bloginfo('url'); ?>/<?php echo $slugname; ?>" method="post">
<label>Keywords</label>
<input type="text" name="keywords" style="width:190px;margin-bottom:10px;" />
<div id="location">

<?php
$location_level1 = get_option('wp_location_level1');
$arr_location_level1 = explode("\n", $location_level1);
echo "<select id='location_level1' name='location_level1'>";
$counter = 0;
foreach ($arr_location_level1 as $item => $value) {
if($counter == 0) {
echo "<option value='' selected='selected'>Anywhere</option>";
echo "<option value='".$value."'>".$value."</option>";
} else {
echo "<option value='".$value."'>".$value."</option>";
}
$counter = $counter + 1;
}
echo "</select>";
