我做到了！我找到了一个函数，使option value=\'slug\'。
功能：
class SH_Walker_TaxonomyDropdown extends Walker_CategoryDropdown{
function start_el(&$output, $category, $depth, $args) {
$pad = str_repeat(\' \', $depth * 3);
$cat_name = apply_filters(\'list_cats\', $category->name, $category);
if( !isset($args[\'value\']) ){
$args[\'value\'] = ( $category->taxonomy != \'category\' ? \'slug\' : \'id\' );
}
$value = ($args[\'value\']==\'slug\' ? $category->slug : $category->term_id );
$output .= "\\t<option class=\\"level-$depth\\" value=\\"".$value."\\"";
if ( $value === (string) $args[\'selected\'] ){
$output .= \' selected="selected"\';
}
$output .= \'>\';
$output .= $pad.$cat_name;
if ( $args[\'show_count\'] )
$output .= \' (\'. $category->count .\')\';
$output .= "</option>\\n";
}
}
和我的所有代码：

<?php get_header(); ?>
<?php global $wp_query;
$aranan= $_GET[\'s\'];
$kategorim = intval($_GET[\'cat\']);
$kateg1= $_GET[\'kategorisec\'];
if (intval($kateg1)<0) { $kateg = ""; } else { $kateg = $kateg1; }
$myterm = get_term( $kategorim, \'fgaleri\' );
global $myslug;
$myslug = $myterm->slug; ?>
