这是一个很奇怪的问题。我会尽可能简单地将其分解。

我正在创建自己的自定义页面查询，其工作方式类似于使用url变量自定义查询结果的存档。

This is my getVar() function...

public static function getVar($name, $default = false) {

    // check our param exists
    if(isset($_REQUEST[$name])) {
      return $_REQUEST[$name];
    }

    // return our default value
    return $default;
}

This is my page-products.php entire query...

// get our filter params
$sSearch       = CF::getVar(\'search\', false);
$sCategory     = CF::getVar(\'cat\', false);
$sSweets       = CF::getVar(\'sweets\', false);
$sChocolates   = CF::getVar(\'chocolate\', false);
$sSnacks       = CF::getVar(\'biscuits-snacks\', false);
$sPackaging    = CF::getVar(\'packaging\', false);
$sSorting      = CF::getVar(\'orderby\', \'random\');

// build our basic filters
$aFilters = array (
    \'post_type\'         => \'product\',
    \'post_status\'       => \'publish\',
    \'posts_per_page\'    => 100,
    \'orderby\'           => \'ASC\',
    \'tax_query\'         => array (
        \'relation\'          => \'AND\',
    )
);

// filter by search query
if($sSearch) {
    $aFilters[\'s\'] = $sSearch;
}

// filter by product category
if($sCategory) {
    // extend our filter array
    $aFilters[\'tax_query\'][] = array (
        \'taxonomy\'  => \'cat\',
        \'field\'     => \'slug\',
        \'terms\'     => array ($sCategory),
    );
}

// filter by product sweets
if($sSweets) {
    // extend our filter array
    $aFilters[\'tax_query\'][] = array (
        \'taxonomy\'  => \'confectionery\',
        \'field\'     => \'slug\',
        \'terms\'     => array ($sSweets),
    );
}

// filter by product chocolates
if($sChocolates) {
    // extend our filter array
    $aFilters[\'tax_query\'][] = array (
        \'taxonomy\'  => \'confectionery\',
        \'field\'     => \'slug\',
        \'terms\'     => array ($sChocolates),
    );
}

// filter by product biscuits & snacks
if($sSnacks) {
    // extend our filter array
    $aFilters[\'tax_query\'][] = array (
        \'taxonomy\'  => \'confectionery\',
        \'field\'     => \'slug\',
        \'terms\'     => array ($sSnacks),
    );
}

// filter by product packaging
if($sPackaging) {
    // extend our filter array
    $aFilters[\'tax_query\'][] = array (
        \'taxonomy\'  => \'packaging\',
        \'field\'     => \'slug\',
        \'terms\'     => array ($sPackaging),
    );
}

// sorting select contents array
$aSorting = array (
    \'newest\'        => \'Latest products\',
    \'oldest\'        => \'Oldest products\',
    \'product_asc\'   => \'Product A-Z\',
    \'product_desc\'  => \'Product Z-A\'
);

if(User::logged_in()) {
    // show price sorting in the dropdown
    $aSorting[\'price_highest\']  = \'Price high-low\';
    $aSorting[\'price_lowest\']   = \'Price low-high\';
}

// determine our sorting filters
switch($sSorting) {

    case \'product_asc\':
        $aFilters[\'orderby\']    = \'title\';
        $aFilters[\'order\']      = \'ASC\';
        break;

    case \'product_desc\':
        $aFilters[\'orderby\']    = \'title\';
        $aFilters[\'order\']      = \'DESC\';
        break;

    case \'price_highest\':
        $aFilters[\'meta_key\']   = \'product_starting_price\';
        $aFilters[\'orderby\']    = \'meta_value_num\';
        $aFilters[\'order\']      = \'DESC\';
        break;

    case \'price_lowest\':
        $aFilters[\'meta_key\']   = \'product_starting_price\';
        $aFilters[\'orderby\']    = \'meta_value_num\';
        $aFilters[\'order\']      = \'ASC\';
        break;

    case \'oldest\':
        $aFilters[\'orderby\']    = \'date\';
        $aFilters[\'order\']      = \'ASC\';
        break;

    case \'latest\':
        $aFilters[\'orderby\']    = \'date\';
        $aFilters[\'order\']      = \'DESC\';
        break;

    case \'random\':
    default:
        $aFilters[\'orderby\']    = \'rand\';
        $aFilters[\'order\']      = \'DESC\';
        break;
}

// build our product object
$oProducts = new WP_Query($aFilters);

所以上面的一切都很好。每个查询都返回正确的结果。

然而，在cat 查询时，我注意到页面的加载时间比其他查询要长一些。

所以我检查了我的网络控制台，这就是正在发生的事情。。。

products?cat=eco-range

正如您在上面看到的，它装载了两次。这没有任何意义？

查看下面我的其他查询的网络结果，这些查询都是一次性的，应该是这样的。

products?sweets=millions

products?packaging=gift-box-midi

products?search=110201

如果有人知道为什么会发生这种情况，或者可以帮助我解决这个问题。那太好了。

提前谢谢。

不幸的是，克里斯的回答没有任何改变。查看更新的已更改

我的自定义类别现在注册为prod_cat 我的url变量也设置为prod_cat 所以不要与保留条款冲突。

https://codex.wordpress.org/WordPress_Query_Vars

这是我在page-products.php.

// get our filter params
$sCategory = CF::getVar(\'prod_cat\', false);

// build our basic filters
$aFilters = array (
    \'post_type\'         => \'product\',
    \'post_status\'       => \'publish\',
    \'posts_per_page\'    => 100,
    \'orderby\'           => \'ASC\',
    \'tax_query\'         => array (
        \'relation\'          => \'AND\',
    )
);

// filter by product prod_cat
if($sCategory) {
    // extend our filter array
    $aFilters[\'tax_query\'][] = array (
        \'taxonomy\'  => \'prod_cat\',
        \'field\'     => \'slug\',
        \'terms\'     => array ($sCategory),
    );
}

它仍然在网络控制台中加载两次。

这没有任何意义。
