将多个数组提交到mysql数据库php

下面是我正在提交的表格一旦提交，它将显示一份调查问卷。echo语句中隐藏的输入类型包含一个问题id数组。问题文本已打印出来。然后，为要填写的答案创建一个文本框，并将其作为不同答案的数组传递-

questionanswer[]

<form action="addanswers.php" method="post"> 
            <fieldset>
                <?php
                $sql = "SELECT * FROM QUESTIONS WHERE QUESTIONNAIRE_FK = '$questionnaireid';";
                $result = mysql_query($sql);

                while($row = mysql_fetch_array($result)) {
                $questionid = $row["QUESTION_ID"];

                if($row["QUESTION_TYPE"] == "ff"){

    echo "<input type='hidden' name = 'questionid[]' value = '".$questionid."'>".$row["QUESTION_TEXT"]." <input type='text' name='questionanswer[]''></br>";
            }
        }
        ?>
            <input type="Submit" value="Submit">
            </fieldset>
            </form>

下面显示addanswers.php。此时此刻，我能够将答案添加到数据库中，该数据库是从问卷中的文本框发布的。我很难将问题id链接到答案文本以将其提交到答案表

$questionanswers = $_POST['questionanswer'];
$questionids = $_POST['questionid'];
foreach($questionanswers as $qa){
$sql = "INSERT INTO ANSWERS (ANSWER_TEXT, QUESTIONNAIRE_FK) values ('$qa', '$questionnaireid')";
mysql_query($sql) or die(mysql_error()); 
}

在此问题上的任何帮助和建议都将不胜感激。提前感谢您的帮助。

好的，我只是想确定您的阵列结构，请尝试以下方法：

$questionanswers = array_map('mysql_real_escape_string', $_POST['questionanswer']);
$questionids = array_map('mysql_real_escape_string', $_POST['questionid']);
foreach($questionanswers as $ind=>$ans){
$sql = "INSERT INTO ANSWERS (ANSWER_TEXT, QUESTIONNAIRE_FK) values ('$ans', '$questionids[$ind]')";
//$ind above contains index of the $questionanswers array-> 0, 1, 2 
//since your $questionids index is also numeric and have the
//same number of array values, we can use this index to refer 
//the corresponding $questionids
mysql_query($sql) or die(mysql_error()); 
}

注:

。它们不再得到维护。看到了吗？相反，学习，并使用，或-将帮助您决定哪一个。如果你选择PDO，.

你能做一个

print\r

的

$\u POST['questionanswer']

和

$\u POST['questionid']]

并粘贴在这里吗？数组（[0]=>male[1]=>05/12/1991）数组（[0]=>1[1]=>2）-当第一个问题是性别，第二个是出生日期时返回。

$questionanswers = array_map('mysql_real_escape_string', $_POST['questionanswer']);
$questionids = array_map('mysql_real_escape_string', $_POST['questionid']);
foreach($questionanswers as $ind=>$ans){
$sql = "INSERT INTO ANSWERS (ANSWER_TEXT, QUESTIONNAIRE_FK) values ('$ans', '$questionids[$ind]')";
//$ind above contains index of the $questionanswers array-> 0, 1, 2 
//since your $questionids index is also numeric and have the
//same number of array values, we can use this index to refer 
//the corresponding $questionids
mysql_query($sql) or die(mysql_error()); 
}
