我添加了一个自定义字段，以使用Metabox获取选定的ID。
array(
'name' => __('Select projects', 'x2-backend'),
'id' => "{$prefix}similar_projects_list",
'type' => 'select_advanced',
'multiple' => true,
'options' => $pages_clients_list,
),
$args_clients = array(
'sort_order' => 'ASC',
'sort_column' => 'post_title',
'hierarchical' => 1,
'exclude' => $post_id,
'include' => '',
'meta_key' => '',
'meta_value' => '',
'authors' => '',
'child_of' => 0,
'parent' => -1,
'exclude_tree' => '',
'number' => '',
'offset' => 0,
'post_type' => 'room',
'post_status' => 'publish'
);
$pages_clients = get_pages($args_clients);
foreach ($pages_clients as $pages_client) {
if ($pages_client->ID !`enter code here`= '') {
$pages_clients_list[$pages_client->ID] = $pages_client->post_title;
}
}
我的观点是使用骨干js。下面是我的代码。
<script type="text/template" id="villashome-item-tpl-similar-projects">
<article class="promosgrid-el withborder with-buttons <?php echo ($sproject->room_bookonlinelink == '' && $sproject->room_enquiryform != 1 ? 'buttonNotActive' : ''); ?> with-grdient with-overlay">
<h3 class="title">
<a title="<%= md.name %>" href="<%= md.permalink %>"><%= md.name %></a>
</h3>
<h4 class="subtitle"><%= md.secondtext_title %></h4>
<div class="img-cont">
<div class="img-hover-overlay">
<a title="<%= md.seo_title %>" href="<%= md.permalink %>">
<img itemprop="image" alt="" src="<%= md.image_thumb_desktop %>" />
</a>
<a title="<%= md.seo_title %>" href="<%= md.permalink %>">
<div class="img-hover-text"><?php echo ___('+ more info', 'x2-frontend', 'villa_collection_more_info'); ?></div>
</a>
</div>
</div>
</article>
</script>
loadmore按钮代码在这里
<?php
$IDs = get_post_meta( get_the_id() , 'ct_mb_similar_projects_list', false );
$total_rooms = x2_get_similar_projects($IDs);
// var_dump(count($total_rooms));
if ( count($total_rooms)>3 ) { ?>
<div id="villas-load-more-div" class="spacer-el loadmore-wrp">
<a id="villas-load-more" class="btns load-more btn-stroke scrollto-action loadmore-gallery-action" href="#"><?php echo ___('Load more X2 Clients', 'x2-frontend', 'gallery_loadmorephotos_btn'); ?></a>
</div>
<?php } ?>
此按钮调用我的script.js文件中的以下代码
if($('.homepage-villas-similar-projects').length>0){
// $.stellar('refresh');
$('.homepage-villas-similar-projects').easyLoad2({
'tpl_selector':'#villashome-item-tpl-similar-projects',
'loadstep': 3,
'getDataType':'getsimilarprojects',
'offset': 3,
});
}
通过此脚本，通过easyload2函数在我的plugin.js中调用getsimilarprojects函数。
easyload2函数在我的plugin.js上
$.fn.easyLoad2 = function (options) {
var el = $(this);
var settings = $.extend({
'tpl_selector': '#blogpost-item-tpl',
'loadstep': 4,
'loadbtn': '.load-more',
'getDataType': 'getposts',
'offset': 0
}, options);
var el_ = $(this);
var jsonurl_ = directory_uri;
var Model = Backbone.Model.extend();
var Collection = Backbone.Collection.extend({
model: Model,
url: jsonurl_
});
var View = Backbone.View.extend({
el: el_,
initialize: function () {
var self = this;
_.each(this.model, function (v, i, l) {
this.template = _.template($(settings.tpl_selector).html(), {md: v});
var d = $(this.template);
self.$el.append(d);
}); $.stellar('refresh');
}
});
var func = {
countData: (settings.offset > 0 ? settings.offset : 0),
myData: '',
step: settings.loadstep,
loadaction: true,
init: function () {
var self = this;
self.scrollTriggers();
if (settings.offset == 0) {
self.data();
}
$('body').on('loadmoredata', function () {
self.data();
});
},
scrollTriggers: function () {
if (this.loadaction === false) {
return;
}
if ($(settings.loadbtn).length === 0) {
$(window).on("scroll", function () {
if (this.loadaction === true) {
var scrollHeight = $(document).height();
var scrollPosition = $(window).height() + $(window).scrollTop();
if ((scrollHeight - scrollPosition) / scrollHeight === 0) {
$('body').trigger('loadmoredata');
}
}
});
} else {
$(settings.loadbtn).on('click', function (e) {
e.preventDefault();
$('body').trigger('loadmoredata');
});
}
},
setCountData: function () {
this.countData += this.myData.length;
},
data: function () {
var self = this;
var myCollection = new Collection();
myCollection.url = jsonurl_ + '?' + settings.getDataType + '=' + self.countData + '&items=' + self.step;
// console.log(myCollection.url);
myCollection.fetch({success: function () {
self.myData = myCollection.toJSON();
self.setCountData();
self.tpl();
}});
},
tpl: function () {
var self = this;
if (self.myData.length !== self.step) {
self.step = self.myData.length;
}
if (self.myData.length === 0) {
self.loadaction = false;
return;
}
if (self.myData[0].count === void 0) {
} else {
if (self.countData >= self.myData[0].count) {
$(settings.loadbtn).hide();
}
}
var myView = new View({model: self.myData});
var scrolltoElement = el_.find('li').eq(self.countData - self.step);
if (self.countData - self.step > 0) {
setTimeout(function () {
$('body').stop(true, true).scrollTo(scrolltoElement, 700, {axis: 'y', offset: {top: 0}, onAfter: function () {
}});
}, 1000);
}
}
};
func.init();
};
我的getsimilarprojects（）在这里
if ( isset( $_REQUEST['getsimilarprojects'] ) ) {
add_action( 'wp_loaded', 'getsimilarprojects');
}
function getsimilarprojects() {
header('Content-type: application/json');
$offset = $_REQUEST['getsimilarprojects'];
$items = $_REQUEST['items'];
$IDs = get_post_meta( get_the_id() , 'ct_mb_similar_projects_list', false );
$args_rooms_ = array(
'posts_per_page' => -1,
'post_type' => 'room',
'posts_per_page' => ($items == 0)? -1: $items,
'offset' => ($offset == 0) ? 0: $offset,
'orderby' => 'menu_order',
'order' => 'ASC',
'post__in' => $IDs,
);
$rooms_query_ = new WP_Query($args_rooms_);
$ar = array();
$i = 0;
while ($rooms_query_->have_posts()) {
$rooms_query_->the_post();
$x2postmeta_room = setX2Globals(get_the_ID());
$ar[$i]['id'] = get_the_ID();
$ar[$i]['name'] = get_the_title();
$ar[$i]['permalink'] = get_permalink();
$ar[$i]['homepageactive'] = ( $x2postmeta_room->room_homepage_dropdown == 1 ? 1 : 0 );
$ar[$i]['order'] = $x2postmeta_room->room_meta_order;
$ar[$i]['price'] = $x2postmeta_room->room_price;
$ar[$i]['feature_title'] = ( $x2postmeta_room->room_feature_title != '' ? $x2postmeta_room->room_feature_title : get_the_title() );
$ar[$i]['feature_status'] = ( $x2postmeta_room->room_feature_status == 1 ? true : false );
$ar[$i]['image_thumb_desktop'] = getFeaturedImage(get_post_thumbnail_id(), 'x2_thumb_374x270', 'x2_thumb_374x270');
$ar[$i]['seo_title_btn'] = $x2postmeta_room->room_seo_title;
$ar[$i]['count'] = $rooms_query_->found_posts;
$i++;
}
wp_reset_query();
echo json_encode($ar);
die();
}
问题是我无法获得'post__in'的$ IDs值。 在本节中不获取get_the_id（）;值。为什么？ ＆我该如何解决？
