我需要能够在functions.php中测试当前正在显示哪个页面。这样我就可以根据显示的页面对我的帖子应用不同的过滤器。
例如，我有两个页面，一个名为buy.php，另一个名称为sold.php。我需要能够在当前显示这些页面时为每个页面定位某种唯一ID，然后使用if语句应用不同的过滤器。
我希望我的代码如何工作;
if(page = buy.php){
$posts['meta_query'][] = array(
'key' => 'property_status',
'value' => 'For Sale'
);
}else if(page = sold.php){
$posts['meta_query'][] = array(
'key' => 'property_status',
'value' => 'Sold'
);
}
我该怎么做？
我需要代码在这个函数中工作，这是过滤我的帖子;
add_action('wp_ajax_customfilter', 'property_filter');
add_action('wp_ajax_nopriv_customfilter', 'property_filter');
function property_filter(){
$posts = array(
'posts_per_page' => -1,
'post_type' => 'property',
'orderby' => 'date'
);
$posts['meta_query'] = array( 'relation' => 'AND' );
// price filtering
if($_POST['min_price'] && !empty($_POST['min_price'])){
$min_price = $_POST['min_price'];
}else{
$min_price = 0;
}
if($_POST['max_price'] && !empty($_POST['max_price'])){
$max_price = $_POST['max_price'];
}else{
$max_price = 10000000;
}
$posts['meta_query'][] = array(
'key' => 'property_price',
'type' => 'NUMERIC',
'value' => array($min_price, $max_price),
'compare' => 'BETWEEN'
);
// bed filtering

$min_beds = $_POST['min_beds'];

$max_beds = $_POST['max_beds'];
}else{
$max_beds = '9+';
}
$posts['meta_query'][] = array(

您可以通过简单的if语句来实现，通过名称检查当前页面，wordpress有一个名为is_page()的函数
<?php
function currentpage()
{
if (is_page('buy')) {
$posts['meta_query'][] = array(
'key' => 'property_status',
'value' => 'For Sale'
);
} elseif (is_page('sold')) {
$posts['meta_query'][] = array(
'key' => 'property_status',
'value' => 'Sold'
);
}
}
add_action('wp_head', 'currentpage');
更新：
根据您编辑的代码，您可以使用：
function property_filter(){
$posts = array(
'posts_per_page' => -1,
'post_type' => 'property',
'orderby' => 'date'
);
$posts['meta_query'] = array( 'relation' => 'AND' );
// price filtering
if($_POST['min_price'] && !empty($_POST['min_price'])){
$min_price = $_POST['min_price'];
}else{
$min_price = 0;
}
if($_POST['max_price'] && !empty($_POST['max_price'])){
$max_price = $_POST['max_price'];
}else{
$max_price = 10000000;
}
$posts['meta_query'][] = array(
'key' => 'property_price',
'type' => 'NUMERIC',
'value' => array($min_price, $max_price),
'compare' => 'BETWEEN'
);
// bed filtering
if($_POST['min_beds'] && !empty($_POST['min_beds'])){
$min_beds = $_POST['min_beds'];
}else{
$min_beds = '1';
}
if($_POST['max_beds'] && !empty($_POST['max_beds'])){
$max_beds = $_POST['max_beds'];
}else{
$max_beds = '9+';
}
$posts['meta_query'][] = array(
'key' => 'bedrooms',
'value' => array($min_beds, $max_beds),
'compare' => 'BETWEEN'
);
//location filtering
if(isset( $_POST['location'] ) && $_POST['location']){
$location = $_POST['location'];
$location_val = stripslashes($location);
$posts['meta_query'][] = array(
'relation' => 'OR',
array(
'key' => 'street',
'value' => $location_val,
'compare' => 'LIKE'
),
array(
'key' => 'town',
'value' => $location_val,
'compare' => 'LIKE'
),
array(
'key' => 'county',
'value' => $location_val,
'compare' => 'LIKE'
),
array(
'key' => 'postcode',
'value' => $location_val,
'compare' => 'LIKE'
)
);
}
// property type filtering
if(isset( $_POST['type'] ) && $_POST['type']){
$posts['meta_query'][] = array(
'key' => 'type_of_property',
'value' => $_POST['type'],
'compare' => 'IN'
);
}
// secondary flash filtering
if(isset( $_POST['flash_type'] ) && $_POST['flash_type']){
$posts['meta_query'][] = array(
'key' => 'optional_category',
'value' => $_POST['flash_type'],
'compare' => 'IN'
);
}
//page type filtering
if (is_page('buy')) {
$posts['meta_query'][] = array(
'key' => 'property_status',
'value' => 'For Sale'
);
} elseif (is_page('sold')) {
$posts['meta_query'][] = array(
'key' => 'property_status',
'value' => 'Sold'
);
}
$query = new WP_Query( $posts );

使用
$_SERVER['REQUEST_URI']
这将给出当前执行脚本的名称。要获得文件名，这将起作用
echo basename($_SERVER['REQUEST_URI'], '?' . $_SERVER['QUERY_STRING']);

使用网页ID
global $post;
$pageid=$post->ID;
if ( $pageid=="2" ) { // 2 = your page id
$posts['meta_query'][] = array(
'key' => 'property_status',
'value' => 'For Sale'
);
}
else if( $pageid=="3" ){ // 3 = your page id
$posts['meta_query'][] = array(
'key' => 'property_status',
'value' => 'Sold'
);
}
使用模板
if (is_page_template( 'templates/buy.php' ) ) {
$posts['meta_query'][] = array(
'key' => 'property_status',
'value' => 'For Sale'
);
}
else if(is_page_template( 'templates/sold.php' ) ){
$posts['meta_query'][] = array(
'key' => 'property_status',
'value' => 'Sold'
);
}
