WordPress-Form不过滤分类结果

我创建了一个插件，该插件使用一个数组，特定于我要为哪些帖子提供分类法，以便创建自定义类别，该分类法的名称是：categoria

我们讨论的是事件预订，因此很明显，每个事件都可以不同于其他事件，每个事件都可以通过meta键的meta\\u值中包含的日期进行搜索：metakey_AMC_data

示例：

形式：

<form method="get" id="advanced-searchform" role="search" action="<?php echo esc_url( home_url( \'/\' ) ); ?>">
    <div class="md-form">

        <input type="hidden" name="search" value="advanced">
        <input
                type="text"
                name="date-picker-example"
                id="date-picker-example"
                class="text-white form-control datepicker"
        >
    <input class="btn btn-sm btn-info" type="submit" id="searchsubmit" value="Cerca" />
</form>

输出数据：

<?php
// Get data from URL into variables
$_name = $_GET[\'date-picker-example\'];

$today = date(\'Ymd\');
// Start the Query
$v_args = array(
    \'post_type\'     =>  array(\'eventi-suite\'), // your CPT
    \'numberpost\'    => -1,
    \'meta_value\'    =>  $_name, // looks into everything with the keyword from your \'name field\'
    \'order\'      => \'ASC\',
    \'orderby\' => \'metakey_AMC_data\',
    \'meta_query\' => array(
        array(
            \'key\'     => \'metakey_AMC_data\',
            \'compare\'   => \'>=\',
            \'value\'     => $today,
        ),
    ),

);
$vehicleSearchQuery = new WP_Query( $v_args );

// Open this line to Debug what\'s query WP has just run
//var_dump($vehicleSearchQuery->request);

// Show the results
if( $vehicleSearchQuery->have_posts() ) :
    while( $vehicleSearchQuery->have_posts() ) : $vehicleSearchQuery->the_post();
        ?><div style="padding-top: 25px;" class="col-md-6"><!-- Card -->
        <!-- Card -->
        <?php


        include(\'content/home_page/card.php\');

        ?>
        <!-- Card -->
        <!-- Card -->
        <?php
        // Assumed your cars\' names are stored as a CPT post title
        ?></div><?php
    endwhile;
else :
    ?><div style="text-align: center;padding-top: 25px;" class="col-md-12"><?php
    _e( \'Ci dispiace, non abbiamo nessun evento da proporti nella data che hai immesso. <br> Prova con un altra data.\', \'textdomain\' );
    ?></div><?php
endif;
wp_reset_postdata();
?>

在这里一切都很好。

url示例：

https://sitename.xxx/?search=advanced&date-picker-example=30-09-2019

现在开始解决问题，因为我在表单中实现了关于分类法的部分

<form method="get" id="advanced-searchform" role="search" action="<?php echo esc_url( home_url( \'/\' ) ); ?>">
    <div class="md-form">

        <input type="hidden" name="search" value="advanced">
        <input
                type="text"
                name="date-picker-example"
                id="date-picker-example"
                class="text-white form-control datepicker"
        >
        <label class="text-white" for="date-picker-example">Seleziona data</label>
        <?php

        /* NEW PART */

        $terms = get_terms(array(
            \'taxonomy\' => \'categoria\',
            \'hide_empty\' => false,
        ));
        ?>
        <select
                name="categoria_evento"
                id="categoria_evento"
                class="browser-default custom-select">
            <option disabled selected>Categorie Eventi</option>
            <?php
            foreach ($terms as $term)
            {
                echo "<option value=\'{$term->slug}\'>{$term->name}</option>";
            }

            /* END NEW PART */

            ?>
        </select>
    </div>

    <input class="btn btn-sm btn-info" type="submit" id="searchsubmit" value="Cerca" />
</form>

输出日期：

<?php
// Get data from URL into variables
$_name = $_GET[\'date-picker-example\'];
$categoria = $_GET[\'categoria_evento\'];
$today = date(\'Ymd\');
// Start the Query
$v_args = array(
    \'post_type\'     =>  array(\'eventi-suite\'), // your CPT
    \'posts_per_page\'    => -1,
    \'meta_value\'    =>  $_name, // looks into everything with the keyword from your \'name field\'
    \'order\'      => \'ASC\',
    \'orderby\' => \'metakey_AMC_data\',
    \'meta_query\' => array(
        array
        (
            \'key\'     => \'metakey_AMC_data\',
            \'compare\'   => \'>=\',
            \'value\'     => $today,

        ),
    ),
    \'tax_query\' => get_terms(array
    (
        array
        (
            \'taxonomy\' => \'categoria\',
            \'field\'    => \'slug\',
            \'terms\'    => $categoria, /*RICHIAMO LA VARIABILE DEL FORM TASSONOMIE*/
            \'hide_empty\' => false,
        )
    )

));
$vehicleSearchQuery = new WP_Query( $v_args );

// Open this line to Debug what\'s query WP has just run
print_r($vehicleSearchQuery->request);

// Show the results
if( $vehicleSearchQuery->have_posts() ) :
    while( $vehicleSearchQuery->have_posts() ) : $vehicleSearchQuery->the_post();
        ?><div style="padding-top: 25px;" class="col-md-6"><!-- Card -->
        <!-- Card -->
        <?php


        include(\'content/home_page/card.php\');

        ?>
        <!-- Card -->
        <!-- Card -->
        <?php
        // Assumed your cars\' names are stored as a CPT post title
        ?></div><?php
    endwhile;
else :
    ?><div style="text-align: center;padding-top: 25px;" class="col-md-12"><?php
    _e( \'Ci dispiace, non abbiamo nessun evento da proporti nella data che hai immesso. <br> Prova con un altra data.\', \'textdomain\' );
    ?></div><?php
endif;
wp_reset_postdata();
?>

但我得到的结果是，它只按日期过滤我，而不按分类法过滤我，因此，通过输入例如2019年9月30日和开胃酒分类法，它会显示我输入日期的所有事件，但显示所有分类法的所有事件，为什么？

url示例：

https://namesite.xxx/categoria/aperitivi/?search=advanced&date-picker-example=30-09-2019
