Question

我有三列数据来自表单。我的目标是如果字段留空，则为每个条目添加小数位。例如，我有BMI，身高和体重。如果表单字段留空，则BMI将有一个小数位，结果为0.0。对于重量，它将为0.00，依此类推。

以下是我现在处理BMI表单字段的代码：

$return['is_spouse'] = ($return['is_spouse'] == 1) ? 'Yes' : 'No';
    if($biometric_data) {
        foreach(self::$biometric_fields as $column_name) {
            if($column_name == 'bmi') {
                $biometrics[$column_name] = number_format($bio[$column_name], 1);
                continue;
            }
            $biometrics[$column_name] = $bio[$column_name];
        }
    }

当尝试将高度或重量部分添加到代码中时，BMI变为空白结果，数字格式仅应用于高度，就像跳过代码的该部分一样。

$return['is_spouse'] = ($return['is_spouse'] == 1) ? 'Yes' : 'No';
    if($biometric_data) {
        foreach(self::$biometric_fields as $column_name) {
            if($column_name == 'bmi') {
                $biometrics[$column_name] = number_format($bio[$column_name], 1);
                continue;
            }
            $biometrics[$column_name] = $bio[$column_name];
        }
    }

    $return['is_spouse'] = ($return['is_spouse'] == 2) ;
    if($biometric_data) {
        foreach(self::$biometric_fields as $column_name) {
            if($column_name == 'height') {
                $biometrics[$column_name] = number_format($bio[$column_name], 2);
                continue;
            }
            $biometrics[$column_name] = $bio[$column_name];
        }
    }

你有两个foreach循环，所以在第二个循环中它会重置＆＃39; bmi＆＃39;字段运行时：

$biometrics[$column_name] = $bio[$column_name];

您需要将两个循环合并为一个：

foreach(self::$biometric_fields as $column_name) {
        if($column_name == 'height') {
            $biometrics[$column_name] = number_format($bio[$column_name], 2);
            continue;
        } else if($column_name == 'bmi') {
            $biometrics[$column_name] = number_format($bio[$column_name], 1);
            continue;
        }
        $biometrics[$column_name] = $bio[$column_name];
    }

带有if语句的foreach循环中的number_format
