Question

为什么我在行值''$ date_result'中出现这种错误？

$datenow = date("Y-m-d");

$firstscheduletimemorning = "08:00AM-12:00NN";

$firstscheduletimeafternoon = "01:00PM-05:00PM";

if ((date('N', strtotime($datenow)) == 6))
{
    $unix_time_for_first_interview = strtotime( $datenow ); // covert date to unix time
    $sec_in_2_days  = 60 * 60 * 24 * 2; // 60 seconds * 60 minutes * 24 hours * 30 days
    $new_unix_time_for_first_interview = $unix_time_for_first_interview + $sec_in_2_days; // add 30 days to unix time
    $date_result = date('Y-m-d', $new_unix_time_for_first_interview ); // convert new unix time to date

    $result = mysql_query("SELECT *
                            FROM tbl_interview_schedule
                            WHERE firstscheduledate = '$date_result'
                            AND firstscheduletime = '$firstscheduletimemorning'");
    $num_rows = mysql_num_rows($result);

    if($num_rows == 15)
    {
        $afternoonresult = mysql_query("SELECT *
                    FROM tbl_interview_schedule
                    WHERE firstscheduledate = '$date_result'
                    AND firstscheduletime = '$firstscheduletimeafternoon'");
        $afternoonnum_rows = mysql_num_rows($afternoonresult);

        if($afternoonnum_rows < 15)
        {
            $HTML = '';

            $HTML .= '<tr>';
                $HTML .= '<td><label>Schedule Interview:</label></td>';
                $HTML .= '<td><input type="text" name="scheduledate" id="scheduledate-txt" class="inputform-design" value='$date_result'></td>';
                $HTML .= '<td><input type="date" name="scheduledatepicker" id="scheduledatepicker-txt" class="inputform-design"></td>';
                $HTML .= '<td><select name="scheduletime" id="scheduletime-txt" class="inputform-design">';
                        $HTML .= '<option value='$firstscheduletimeafternoon'>$firstscheduletimeafternoon</option>';
                        $HTML .= '<option value="08:00AM - 12:00NN">08:00AM - 12:00NN</option>';
                        $HTML .= '<option value="01:00PM - 05:00PM">01:00PM - 05:00PM</option>';
                    $HTML .= '</select>';
                $HTML .= '</td>';
            $HTML .= '</tr>';
        }
            echo $HTML;
   }
}

Answer 1

$HTML .= '<td><input type="text" name="scheduledate" id="scheduledate-txt" class="inputform-design" value='$date_result'></td>'

应该是：

$HTML .= '<td><input type="text" name="scheduledate" id="scheduledate-txt" class="inputform-design" value='.$date_result.'></td>'

和

$HTML .= '<option value='$firstscheduletimeafternoon'>$firstscheduletimeafternoon</option>';

应该是：

$HTML .= '<option value='.$firstscheduletimeafternoon.'>'.$firstscheduletimeafternoon.'</option>';

*请注意mysql扩展名is now deprecated and will be removed sometime in the future。那是因为它古老，充满了不良做法，缺乏一些现代特色。不要用它来编写新代码。请改用PDO或mysqli_*。

Answer 2

$HTML .= '<option value='$firstscheduletimeafternoon'>$firstscheduletimeafternoon</option>';

应该是

$HTML .= '<option value="'.$firstscheduletimeafternoon.'">'.$firstscheduletimeafternoon.'</option>';

注意连接字符串的.。

$HTML .= "<option value='$firstscheduletimeafternoon'>$firstscheduletimeafternoon</option>";

也是一种选择。如果使用双引号，则可以解释其中的变量。

Answer 3

你在线上错过了连接运算符。它应该是

$HTML .= '<td><input type="text" name="scheduledate" id="scheduledate-txt" class="inputform-design" value='.$date_result.'></td>';

你也错过了其他地方。（请参阅option行）

Answer 4

您希望使用连接字符串运算符，如下所示：

value="'.$date_result.'"

解析错误：语法错误，意外的T_VARIABLE
