Foreach不显示多个内容

Question

我在为 WordPress 创建的简码中遇到了一个小问题。 foreach 循环不会每次都显示多个帖子。我不确定为什么要这样做，因为如果我 var_dump $post 变量它表明两个帖子都可用于该变量，有人可以帮我吗？

代码：

function notes_shortcode($atts) {
global $post;

$atts = shortcode_atts( array( 'category' => $args["category"]), $atts, 'notes' );
$args = array( 'category_name' => $atts["category"]);
$posts = get_posts( $args );
$date = get_the_date( 'd', $post->ID );
$month = get_the_date( 'M', $post->ID );

    foreach( $posts as $post ) {
        setup_postdata($post);
        $imgURL = getpostImage( $post->ID );
        $title = get_the_title( $post->ID );
        $content = substr(get_the_content() , 0, 125); 
        $post = '<div class="animated fadeInUp" data-animation="fadeInUp" data-delay="200" style="opacity: 0;">';
        $post .= '<div class="col-md-4 bloglist">';
        $post .= '<div class="post-content">';
        $post .= '<div class="post-image">';
        $post .= '<div class="flexslider blog-slider">';
        $post .= '<div class="overlay" style="opacity: 0;"></div>';
        $post .= '<div class="flex-viewport" style="overflow: hidden; position: relative;">';
        $post .= '<ul class="slides" style="width: 800%; -webkit-transition: 0s; transition: 0s; -webkit-transform: translate3d(-350px, 0px, 0px);">';
        $post .= '<li class="clone" aria-hidden="true" style="width: 350px; float: left; display: block;"> <img src="' . $imgURL  . '" alt="" draggable="false"> </li>';
        $post .= '<li class="flex-active-slide" style="width: 350px; float: left; display: block;"> <img src="' . $imgURL  . '" alt="" draggable="false"> </li>';
        $post .= '<li style="width: 350px; float: left; display: block;"> <img src="' . $imgURL  . '" alt="" draggable="false"> </li>';
        $post .= '<li class="clone" aria-hidden="true" style="width: 350px; float: left; display: block;"> <img src="' . $imgURL  . '" alt="" draggable="false"></li>';
        $post .= '</ul></div></div></div>';
        $post .= '<div class="date-box"><span class="day">' . $date . '</span>';
        $post .= '<span class="month">' . $month . '</span> </div>';
        $post .= '<div class="post-text">';
        $post .= '<h3><a href="css/#">' . $title . '</a></h3>';
        $post .= '<p> ' . $content . '<br>';
        $post .= ' <a href="#" class="btn-text">Read More</a></p></div></div></div></div>';
        return $post;
    }
}
add_shortcode( 'notes', 'notes_shortcode' );

function getpostImage($postid) {
    if (has_post_thumbnail($post->ID)){
            $imgArray = wp_get_attachment_image_src( get_post_thumbnail_id( $post->ID), 'thumbnail' );
            $imgURL = $imgArray[0];
            return $imgURL;
    }
}

谢谢..

您正在返回函数，这意味着您正在使函数结束。你可以做的是发送数组然后循环它later.Use下面的代码

function notes_shortcode($atts) {
global $post;

$atts = shortcode_atts( array( 'category' => $args["category"]), $atts, 'notes' );
$args = array( 'category_name' => $atts["category"]);
$posts = get_posts( $args );
$date = get_the_date( 'd', $post->ID );
$month = get_the_date( 'M', $post->ID );
$array = array();
    foreach( $posts as $post ) {
        setup_postdata($post);
        $imgURL = getpostImage( $post->ID );
        $title = get_the_title( $post->ID );
        $content = substr(get_the_content() , 0, 125); 
        $post = '<div class="animated fadeInUp" data-animation="fadeInUp" data-delay="200" style="opacity: 0;">';
        $post .= '<div class="col-md-4 bloglist">';
        $post .= '<div class="post-content">';
        $post .= '<div class="post-image">';
        $post .= '<div class="flexslider blog-slider">';
        $post .= '<div class="overlay" style="opacity: 0;"></div>';
        $post .= '<div class="flex-viewport" style="overflow: hidden; position: relative;">';
        $post .= '<ul class="slides" style="width: 800%; -webkit-transition: 0s; transition: 0s; -webkit-transform: translate3d(-350px, 0px, 0px);">';
        $post .= '<li class="clone" aria-hidden="true" style="width: 350px; float: left; display: block;"> <img src="' . $imgURL  . '" alt="" draggable="false"> </li>';
        $post .= '<li class="flex-active-slide" style="width: 350px; float: left; display: block;"> <img src="' . $imgURL  . '" alt="" draggable="false"> </li>';
        $post .= '<li style="width: 350px; float: left; display: block;"> <img src="' . $imgURL  . '" alt="" draggable="false"> </li>';
        $post .= '<li class="clone" aria-hidden="true" style="width: 350px; float: left; display: block;"> <img src="' . $imgURL  . '" alt="" draggable="false"></li>';
        $post .= '</ul></div></div></div>';
        $post .= '<div class="date-box"><span class="day">' . $date . '</span>';
        $post .= '<span class="month">' . $month . '</span> </div>';
        $post .= '<div class="post-text">';
        $post .= '<h3><a href="css/#">' . $title . '</a></h3>';
        $post .= '<p> ' . $content . '<br>';
        $post .= ' <a href="#" class="btn-text">Read More</a></p></div></div></div></div>';
        $array[] = $post;
    }
return $array;
}
add_shortcode( 'notes', 'notes_shortcode' );

function getpostImage($postid) {
    if (has_post_thumbnail($post->ID)){
            $imgArray = wp_get_attachment_image_src( get_post_thumbnail_id( $post->ID), 'thumbnail' );
            $imgURL = $imgArray[0];
            return $imgURL;
    }
}

好的，我解决了这个问题。我使用 WordPress 过滤器挂钩 $buff 变量并将其返回到循环外，如果有人需要，下面是解决方案。

function notes_shortcode($atts) {
global $post;
global $buf;

$atts = shortcode_atts( array( 'category' => $args["category"], 'posts_per_page' => $args["posts_per_page"]), $atts, 'notes' );
$args = array( 'category_name' => $atts["category"], 'posts_per_page' => $atts["posts_per_page"] );
$posts = get_posts( $args );
$date = get_the_date( 'd', $post->ID );
$month = get_the_date( 'M', $post->ID );
$buf = '';
$postHolder = array(); 

foreach( $posts as $post ) {
        setup_postdata($post);
        $imgURL = getpostImage( $post->ID );
        $title = get_the_title( $post->ID );
        $content = substr(get_the_content() , 0, 125); 

        $buf .= '<div class="animated fadeInUp" data-animation="fadeInUp" data-delay="200" style="opacity: 0;">';
        $buf .= '<div class="col-md-4 bloglist">';
        $buf .= '<div class="post-content">';
        $buf .= '<div class="post-image">';
        $buf .= '<div class="flexslider blog-slider">';
        $buf .= '<div class="overlay" style="opacity: 0;"></div>';
        $buf .= '<div class="flex-viewport" style="overflow: hidden; position: relative; max-width: 350px; max-height: 175px; padding-bottom: 15px; margin-bottom: 15px;">';
        $buf .= '<ul class="slides" style="width: 800%; -webkit-transition: 0s; transition: 0s; -webkit-transform: translate3d(-350px, 0px, 0px);">';
        $buf .= '<li class="clone" aria-hidden="true" style="width: 350px; float: left; display: block;"> <img src="' . $imgURL  . '" alt="" draggable="false"> </li>';
        $buf .= '<li class="flex-active-slide" style="width: 350px; float: left; display: block;"> <img src="' . $imgURL  . '" alt="" draggable="false"> </li>';
        $buf .= '<li style="width: 350px; float: left; display: block;"> <img src="' . $imgURL  . '" alt="" draggable="false"> </li>';
        $buf .= '<li class="clone" aria-hidden="true" style="width: 350px; float: left; display: block;"> <img src="' . $imgURL  . '" alt="" draggable="false"></li>';
        $buf .= '</ul></div></div></div>';
        $buf .= '<div class="date-box"><span class="day">' . $date . '</span>';
        $buf .= '<span class="month">' . $month . '</span> </div>';
        $buf .= '<div class="post-text">';
        $buf .= '<h3><a href="css/#">' . $title . '</a></h3>';
        $buf .= '<p> ' . $content . '<br>';
        $buf .= ' <a href="#" class="btn-text">Read More</a></p></div></div></div>';
        $buf .= apply_filters( 'post_class', '</div>', $atts );
    } 
    $buf .= apply_filters( 'post_class', '', $atts );
    return $buf;
}

add_shortcode( 'notes', 'notes_shortcode' );

function getpostImage($postid) {
    if (has_post_thumbnail($post->ID)){
            $imgArray = wp_get_attachment_image_src( get_post_thumbnail_id( $post->ID), 'thumbnail' );
            $imgURL = $imgArray[0];
            return $imgURL;
    }
}

谢谢大家的帮助..
