讀取$ _POST陣列確定這是我的腳本: -如何在PHP
<form action="results.php" method="post">
<?php mysql_select_db($database, $databasename) or die("Opps some things went wrong");
$sqlQueryTestDisplay = mysql_query("SELECT * FROM questions WHERE test_id='$testtaken_id' ORDER BY question_id ASC");
$i = 0;
while($DisplayItems = mysql_fetch_array($sqlQueryTestDisplay))
{
$i = $i + 1;
$question_id = $DisplayItems['question_id'];
$question = $DisplayItems['question'];
$opta = $DisplayItems['opta'];
$optb = $DisplayItems['optb'];
$optc = $DisplayItems['optc'];
$optd = $DisplayItems['optd'];
$answer[$i] = $DisplayItems['answer'];
$thisAnswer = $answer[$i];
echo '<li>'.$question.'</li>';
echo '<p>';
echo '<label><input type="radio" name="optans'.$i.'" value="radio" id="RadioGroup'.$i.'_0" />'.$opta.'</label>';
echo '<label><input type="radio" name="optans'.$i.'" value="radio" id="RadioGroup'.$i.'_1" />'.$optb.'</label>';
echo '<label><input type="radio" name="optans'.$i.'" value="radio" id="RadioGroup'.$i.'_2" />'.$optc.'</label>';
echo '<label><input type="radio" name="optans'.$i.'" value="radio" id="RadioGroup'.$i.'_3" />'.$optd.'</label>';
echo '<input name="ans'.$i.'" type="hidden" value="'.$thisAnswer.'" />';
echo '</p>';
}
echo '<input name="total_questions" type="hidden" value="'.$i.'" />';
echo '<input name="test_id" type="hidden" value="'.$TestID.'" />';
?>
<input name="submittest" type="submit" />
</form>
正如你可以看到我使用數組存儲在不同的字段中的值。現在,我即頁面result.php上的下一個頁面上我寫這: -
<?php
if(isset($_POST['submittest']))
{
global $ans1;
$TotalQuestions = $_POST['total_questions'];
$TestID = $_POST['test_id'];
$TestResult = 0;
for ($i=1; $i<=$TotalQuestions; $i++)
{
$ansValue = 'ans'.$i;
$optansValue = 'optans'.$i;
$ans = $_POST[$ansValue];
$optans = $_POST[$optansValue];
if ($ans == $optans)
{
$TestResult = $TestResult + 1;
}
}
$st_id = $row_Recordset1['id'];
mysql_select_db($database, $databasename) or die("Opps some things went wrong");
$sqlQueryInsertResult = mysql_query("INSERT INTO results (student_id, test_id, test_result) VALUES ('$st_id', '$TestID', '$TestResult')");
header('location:results.php');
}
?>
現在我的腳本不讀書ANS1,ANS2 .....等等,甚至quesans1,quesans2 ... ..等等。
我認爲問題出在我打電話使用$ _ POST方法數組的方式。
是語法正確的,我怎麼能解決這個問題...請幫助:|
無關的問題,但...你包括* *回答您的問題在HTML?如果是這樣,用戶將能夠通過查看頁面的源代碼來查看所有答案! – bfavaretto 2012-02-15 14:25:06
將name =「submittest」添加到
