联系表单7 WordPress中选择字段的自定义验证消息

Question

我想显示选择字段的自定义消息。我正在使用插件“联系表单7自定义验证”来获取自定义消息，但它不适用于选择字段。是否有一个钩子只能为select字段修改我的消息，因为我的验证消息的其余部分没问题。

更新：

我有以下字段：

<div class="form-half">
                              <label for="state" class="visuallyhidden">state</label>[select* state id:state first_as_label "State" "Alabama" "Alaska" "American Samoa" "Arizona" "Arkansas" "California" "Colorado" "Connecticut" "Delaware" "District of Columbia" "Florida" "Georgia" "Guam" "Hawaii" "Idaho" "Illinois" "Indiana" "Iowa" "Kansas" "Kentucky" "Louisiana" "Maine" "Maryland" "Massachusetts" "Michigan" "Minnesota" "Mississippi" "Missouri" "Montana" "Nebraska" "Nevada" "New Hampshire" "New Jersey" "New Mexico" "New York" "North Carolina" "North Dakota" "Northern Marianas Islands" "Ohio" "Oklahoma" "Oregon" "Pennsylvania" "Puerto Rico" "Rhode Island" "South Carolina" "South Dakota" "Tennessee" "Texas" "Utah" "Vermont" "Virginia" "Virgin Islands" "Washington" "West Virginia" "Wisconsin" "Wyoming"]</div>

我使用以下钩子来做到这一点，但没有工作：

add_filter( 'wpcf7_validate_select*', 'custom_select_validation_filter', 20, 2 );

function custom_select_validation_filter( $result, $tag ) {
    if ( 'state' == $tag->name ) {

        echo $test_custom_select = $_POST['state'];
        if ( empty( $test_custom_select ) || $test_custom_select == 'State' ) {
            // Example of result
            $result->invalidate($tag, __( 'Please enter state name', 'CF7' ));
        }

    }

    return $result;
}

但这不起作用。

请尝试以下代码：

add_filter( 'wpcf7_validate_select', 'custom_select_validation_filter', 20, 2 );


function custom_select_validation_filter( $result, $tag ) {
    if ( 'state' == $tag->name ) {

        $test_custom_select = $_POST['state'];
        if ( empty( $test_custom_select ) || $test_custom_select == 'State' ) {
            // Example of result
            $result->invalidate($tag, __( 'your-select is required', 'CF7' ));
        }

    }
    elseif ( 'second-select' == $tag->name ){

        $test_custom_select = $_POST['second-select'];
        if ( empty( $test_custom_select ) ) {
            // Example of result
            $result->invalidate($tag, __( 'second-select is required', 'CF7' ));
        }

    }

    return $result;
}

测试和工作。

// For the custom Price for shuttle transport

 */
function shuttleprice() {

    $id_a = null;      
    $max_personen = get_field("maximale_anzahl", $id_a);
    $max_personen_gesamt = get_field("anzahl_maximale_personen_im_shuttle_mit_aufpreis", $id_a);
    $aufpreis = get_field("aufpreis_pro_person_im_shuttle", $id_a);

    $inkl = "";
    $more = "";

    for ($x = 1; $x <= $max_personen; $x++) {
        if($x == 1) {
            $inkl = $inkl."<option value='".$x."'>für ".$x." Person (inklusive)</option>";
        } else {

            $lauf++;
        }
    }

    $html = '<option value="0">bitte wählen</option>'.$inkl.$more;

    return $html;
}


add_action( 'wpcf7_init', 'wpcf7_add_form_tag_select_shuttleprice' );
function wpcf7_add_form_tag_select_shuttleprice() {
    wpcf7_add_form_tag(
        array(
            'select_shuttleprice',
            'select_shuttleprice*',
        ),
        'wpcf7_select_shuttleprice_form_tag_handler',
        array(
            'name-attr'         => true,
            'selectable-values' => true,

}

function wpcf7_select_shuttleprice_form_tag_handler( $tag ) {
    return str_replace( '</select>', shuttleprice() . '</select>', str_replace(
        '<option value="">---</option>', '', wpcf7_select_form_tag_handler( $tag )

}


add_filter( 'wpcf7_validate_select_shuttleprice', 'wpcf7_select_shuttleprice_validation_filter', 10, 2 );
add_filter( 'wpcf7_validate_select_shuttleprice*', 'wpcf7_select_shuttleprice_validation_filter', 10, 2 );

    $name = $tag->name;
    $empty = ( empty( $_POST[ $name ] ) || '0' === $_POST[ $name ] );

        $result->invalidate( $tag, wpcf7_get_message( 'invalid_required' ) );
    }

    return $result;

有了这个短代码

[select_shuttleprice* shuttleprice-1 class:shuttleprice]
