Question

这几乎是我已经问过的question的更新版本。我很确定我的j查询不会干扰。出于某种原因，我在这种情况下的if语句不应该触发。长话短说：我能够限制回复，但无法显示错误消息。

有些if工作正在进行中，我一定会指出那个没有的。

提前致谢。

这是工作：

if(isset($_POST['sub_comment_reply'])) {
    if($_POST['reply'] == "" ) {
    $valid = false;
    $error_msgs_reply[] = "Whoops! You forgot to write your reply.";
    }else{

        $query = "SELECT COUNT(*) FROM `CysticAnswers_replies`
                  WHERE `FromUserID` = $auth->id
                    AND `date` = CURDATE()";
        $result = mysql_query($query, $connection);
        $post_count = mysql_result($result, 0);
        $max_reply_per_day = 5;




        //Debugging lines
        echo "Query: {$query}<br>\n";
        echo "Post count for user id {$auth->id} is {$post_count}<br>\n";

        if($post_count >= $max_reply_per_day){
                $valid = false;
                $error_msgs_replies_max[] = "Whoops! You have reached your limit of answers for the day.";
        }
        else
        {
        $query = "INSERT INTO `CysticAnswers_replies`
                                            ( `QuestionCommentID`,
                                              `FromUserID`,
                                              `comment`,
                                              `status`,
                                              `date`,
                                              `time`
                                            ) VALUES (

                                            '" . mysql_real_escape_string($_POST['comment']) ."',
                                            '" . $auth->id ."',
                                            '" . mysql_real_escape_string($_POST['reply'])."',
                                            'active',
                                            '" . date("Y-m-d") . "',
                                            '" . date("G:i:s") . "')";

            mysql_query($query, $connection);



}

这是尝试触发错误消息但未被触发的部分：

<?php if(isset($_POST['sub_comment_reply']) && $post_count >= $max_reply_per_day ) {

    foreach($error_msgs_replies_max as $msg) { ?>

                    </form>

        <?php } ?>

Answer 1

你试过了吗？

if (isset($error_msgs_replies_max)) foreach($error_msgs_replies_max as $msg) {
  // Do stuff
} else print 'No variable $error_msgs_replies_max';

Answer 2

您同时使用$error_msgs_replies_max和$error_msgs_reply来捕捉错误也是错误的...请仅使用一个$error_msgs_reply

您也可以替换

   foreach($error_msgs_replies_max as $msg) { ?>

带

foreach ($error_msgs_reply as $msg)

如果声明没有触发
