Question

我正在进行学校民意调查，我发现了一个适合我作为新手here的需求。但是当我尝试将选项从收音机更改为复选框时，我遇到了发布数组的问题。这是代码：

<?php require_once('Connections/conn_vote.php'); ?>
<?php
if (!function_exists("GetSQLValueString")) {
function GetSQLValueString($theValue, $theType, $theDefinedValue = "", $theNotDefinedValue = "") 
{
  $theValue = get_magic_quotes_gpc() ? stripslashes($theValue) : $theValue;

  $theValue = function_exists("mysql_real_escape_string") ? mysql_real_escape_string($theValue) : mysql_escape_string($theValue);

  switch ($theType) {
    case "text":
      $theValue = ($theValue != "") ? "'" . $theValue . "'" : "NULL";
      break;    
    case "long":
    case "int":
      $theValue = ($theValue != "") ? intval($theValue) : "NULL";
      break;
    case "double":
      $theValue = ($theValue != "") ? "'" . doubleval($theValue) . "'" : "NULL";
      break;
    case "date":
      $theValue = ($theValue != "") ? "'" . $theValue . "'" : "NULL";
      break;
    case "defined":
      $theValue = ($theValue != "") ? $theDefinedValue : $theNotDefinedValue;
      break;
  }
  return $theValue;
}
}

$editFormAction = $_SERVER['PHP_SELF'];
if (isset($_SERVER['QUERY_STRING'])) {
  $editFormAction .= "?" . htmlentities($_SERVER['QUERY_STRING']);
}

if ((isset($_POST["MM_insert"])) && ($_POST["MM_insert"] == "form1")) {
  $insertSQL = sprintf("INSERT INTO poll (id, question) VALUES (%s, %s)",
                       GetSQLValueString($_POST['id'], "int"),
                       GetSQLValueString($_POST['Poll'], "text"));
					   
  mysql_select_db($database_conn_vote, $conn_vote);
  $Result1 = mysql_query($insertSQL, $conn_vote) or die(mysql_error());

  $insertGoTo = "pollsgt.php";
  if (isset($_SERVER['QUERY_STRING'])) {
    $insertGoTo .= (strpos($insertGoTo, '?')) ? "&" : "?";
    $insertGoTo .= $_SERVER['QUERY_STRING'];
  }
  header(sprintf("Location: %s", $insertGoTo));
}

$colname_rs_vote = "-1";
if (isset($_GET['recordID'])) {
  $colname_rs_vote = $_GET['recordID'];
}
mysql_select_db($database_conn_vote, $conn_vote);
$query_rs_vote = sprintf("SELECT * FROM poll WHERE id = %s", GetSQLValueString($colname_rs_vote, "int"));
$rs_vote = mysql_query($query_rs_vote, $conn_vote) or die(mysql_error());
$row_rs_vote = mysql_fetch_assoc($rs_vote);
$totalRows_rs_vote = mysql_num_rows($rs_vote);

$('.subscriber :checkbox').change(function () {
    var $cs=$(this).closest('.subscriber').find(':checkbox:checked');
    if ($cs.length > 2) {
        this.checked=false;
    }
});
</script>
</body>
</html>
<?php
mysql_free_result($rs_vote);
?>

然而，当我运行代码时，数据库会选择一个数组而不是单独的投票。

如何使其发布不是数组的单独值？提前谢谢！

如果您希望将$_POST['Poll']的字符串解释存储在数据库中，请更改$ insertSQL的代码：

$insertSQL = sprintf("INSERT INTO poll (id, question) VALUES (%s, %s)",
                       GetSQLValueString($_POST['id'], "int"),
                       GetSQLValueString(implode(",", $_POST['Poll']), "text"));

PHP - 轮询在数据库中发布数组
