如何从wp_Dropdown_Categories获取类别插件

我正在自定义一个插件。我需要它来显示层次结构中的类别列表，这是我使用插件的所有功能得到的。我正在使用wp_dropdown_categories, 但我想将类别列表显示为它们的slug，而不是它们的类别名称。有什么建议吗？

以下是我目前掌握的情况：

function replace_id_for_slug( $option ) {
    $categories = get_categories( "hide_empty=0" );
    preg_match( \'/value="(\\d*)"/\', $option[0], $matches );

    $id = $matches[1];
    $selectID = $nextItem;
    $slug = get_cat_slug( $id );

    foreach ( $categories as $category ) {
        if ( $category->cat_ID == $id ) {

        }
    }
    return preg_replace( "/value=\\"(\\d*)\\"/", "value=\\"$slug\\"", $option[0] );
}

$select = wp_dropdown_categories(
    "hierarchical=1&hide_empty=0&echo=0&name=field_$nextItem&id=$selectID&class=categoriesBox"
);

echo $select;

我忘了提到这是用于管理后端的。我试过和沃克班的同学一起玩，但我不知所措。你知道还有什么其他方法可以做到这一点吗？

class WPSE_Cat_Slug_Walker extends Walker_Category { function start_el( &$output, $category, $depth, $args, $id = 0 ) { $pad = str_repeat(\' \', $depth * 3); $output .= "\\t<option class=\\"level-$depth\\" value=\\"".$category->term_id."\\""; if ( $category->term_id == $args[\'selected\'] ) $output .= \' selected="selected"\'; $output .= \'>\'; $output .= $pad.$category->slug; // The Slug! if ( $args[\'show_count\'] ) $output .= \'  (\'. $category->count .\')\'; $output .= "</option>\\n"; } }

$select = wp_dropdown_categories( array ( \'hierarchical\' => 1, \'hide_empty\' => 0, \'echo\' => 0, \'name\' => "field_$nextItem", \'id\' => $selectID, \'class\' => \'categoriesBox\', \'walker\' => $wpse_cat_slug_walker // the walker ) );

<?php wp_dropdown_categories( \'taxonomy=my_taxonomy&value_field=slug\' ); ?> <script type="text/javascript">  </script>

class FGW_Cat_Slug_Walker extends Walker_CategoryDropdown{ public function start_el(&$output, $category, $depth = 0, $args = array(), $id = 0){ $pad = str_repeat(\' \', $depth * 3); // Create the padding (before nested terms) /** Generate the HTML for this option */ $output.= sprintf("\\t". \'<option class="%1$s" value="%2$s" %3$s>%4$s%5$s</option>\', /** %1$s - \'class\' attribute */ \'level-\' . $depth, /** %2$s - \'value\' attribute */ $category->slug, /** %3$s - \'selected\' attribute */ ($category->slug == $args[\'selected\']) ? \' selected="selected"\' : \'\', /** %4$s - option text */ $category->name, /** %5$s - The term count */ ($args[\'show_count\']) ? \'  (\' . $category->count . \')\' : \'\' ); } }
