Question

我想显示选择字段的自定义消息。我正在为自定义消息使用插件“联系表单7自定义验证”，但不适用于选择字段。是否有一个钩子可以仅在选择字段中修改我的消息，因为其余的验证消息都可以。

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>

我已经使用以下钩子来做到这一点，但不起作用：

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。

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;
}

经测试可正常工作。
