我的问题是,当我使用会话变量在不同的 php 脚本之间复制我的数组元素时,什么都没有打印出来。以下是我的两个 php 文件。
文件1.php
$SQL = "SELECT * FROM tblquestions";
if ($db_found) {
$result = mysql_query($SQL);
$numRows = mysql_num_rows($result); //return number of rows in the table
echo '<FORM NAME ="form1" METHOD ="POST" ACTION ="file2.php">';
for ($i = 1; $i <= 2; $i++)
{
$db_field = mysql_fetch_assoc($result);
$qID[$i] = $db_field['QID'];
$question[$i] = $db_field['Question'];
$A[$i] = $db_field['qA'];
$B[$i] = $db_field['qB'];
$C[$i] = $db_field['qC'];
echo '<P>';
print $question[$i];
echo '<P>';
echo "<INPUT TYPE = 'Radio' Name = '".$qNum."' value= 'A'>";
print $A[$i];
echo '<P>';
echo "<INPUT TYPE = 'Radio' Name = '".$qNum."' value= 'B'>";
print $B[$i];
echo '<P>';
echo "<INPUT TYPE = 'Radio' Name = '".$qNum."' value= 'C'>";
print $C[$i];
//if (isset($_POST[$name_Value]))
$survey_Answers[$i-1] = $_POST[$qNum];
print '</BR>'.$survey_Answers[$i-1]."</BR>";
$question_Number = ltrim($qNum,'q');
$question_Number++;
$qNum ='q'.$question_Number;
}
echo '<p>';
session_start();
$_SESSION['answers'] = $survey_Answers;
echo '<INPUT TYPE = "Submit" Name = "Submit1" VALUE = "Click here to vote">';
echo '</form>';
在我的第二个文件(file2.php)上,我有以下内容:
<?PHP
session_start();
if (isset($_POST['Submit1'])) {
$results = $_SESSION['answers'];
print $results[0];
?>
执行上述代码时没有打印任何内容。
