Question

我需要帮助在categories id 9中循环使用此模板。这是我到目前为止所做的：

$columns     = false;
$rows        = false;
$image_sizes = array();

if ( have_posts() ) :

    if ( is_page() ) {

        $grid_portfolio = new GridPortfolio( get_the_ID() );
    // Sets: $orientation, $aspect_ratio, $grid_size, $image_sizes, $columns, $rows
        extract( $grid_portfolio->get_options() );

    } else {

        $default_grid_portfolio = it_find_page_by_template( 'template-portfolio-grid.php', array( 'post_status' => 'publish' ) );

        if ( $default_grid_portfolio ) {
            $grid_portfolio = new GridPortfolio( $default_grid_portfolio[0]->ID );
            extract( $grid_portfolio->get_options() );
        }

        /**
         * We are on a Project Type page,
         * thus we need to check if there is any overriden options.
         *
         * Sets: $orientation, $aspect_ratio, $grid_size, $image_sizes, $columns, $rows
         */
        extract( fluxus_project_type_grid_options( get_queried_object()->term_id ) );

    }
    if ( ! is_numeric( $columns ) ) {
        $columns = 4;
    }

    if ( ! is_numeric( $rows ) ) {
        $rows = 3;
    }

    $max_size = $orientation == 'horizontal' ? $rows : $columns;

    fluxus_add_html_class( 'layout-portfolio-grid layout-portfolio-grid-' . $orientation );

    if ( $orientation != 'vertical' ) {
        fluxus_add_html_class( 'horizontal-page' );
    }
    get_header();

    fluxus_query_portfolio( array(
        'fluxus-project-type' => get_query_var( 'fluxus-project-type' )
    ) );

    ?>
    <div id="main" class="site">

        <div class="portfolio-grid" data-aspect-ratio="<?php esc_attr_e( $aspect_ratio ); ?>" data-orientation="<?php esc_attr_e( $orientation ); ?>" data-columns="<?php echo $columns; ?>" data-rows="<?php echo $rows; ?>"><?php

            while ( have_posts() ) :

                the_post();
    $project = new PortfolioProject( get_the_ID() );
                $featured = $project->get_featured_media();

                if ( ! $featured ) continue; // We have no media on this project, nothing to show.

                $thumbnail = FLUXUS_IMAGES_URI . '/no-portfolio-thumbnail.png';
                $thumbnail_2x = '';

                $thumbnail_data = $featured->get_thumbnail( 'fluxus-thumbnail' );
                $thumbnail_data_2x = $featured->get_thumbnail( 'fluxus-thumbnail-2x', 'fluxus-thumbnail' );

                if ( $thumbnail_data ) {
                    $thumbnail = $thumbnail_data['src'];
                }

    if ( isset( $image_sizes[get_the_ID()] ) ) {
                    $size = $image_sizes[get_the_ID()];
                    $size = $size > $max_size ? $max_size : $size;
                } else {

由于您提到要将其放入模板中，因此您应该review the WP template hierarchy。这将允许您指定在特定情况下使用哪些模板，例如查看特定类别时。这就像重命名模板category-9.php一样简单：当您访问example.com/blog/?cat=9

时，将使用此模板

如果您正在讨论在另一个模板中显示Categpry帖子（对于eaxmple，在主页上），那么您需要查询一些帖子，然后才能实际循环它们;你需要在开幕if ( have_posts() )之前这样做。您可以为查询设置不同的参数，以更改您收到的帖子。 One of these available parameters is cat，可让您指定要从中获取帖子的类别。你会这样使用它：

$args = (
    'cat' => 9
);
$query = new WP_Query($args);
if ($query->have_posts()) {
    while ($query->have_posts()) {) {
    // The rest of the code here

我强烈建议你read up on how WP_Query works
