在php

Question

<label><input type="radio" name="rval<?php echo $qid; ?>[]" value="2" id="rval<?php echo $qid; ?>_1" style="cursor: pointer">2&emsp;</label>

我在php中添加了上面的代码。并将此值称为插入sql，如下所示。

<?php
$fqid  = mysql_real_escape_string($fqid);
$qrval = isset($_POST["rval$fqid"]);
?>

但我没有从单选按钮获取任何值。 qid＆amp; fqid是一样的。任何帮助将不胜感激。

<?php
	$pid=$_GET["pid"];
	$user=$_SESSION["user"];
	$centre=$_SESSION["centre"];
	$credate=date('d-m-Y');
	
	if(isset($_POST["pf_submit"])){
$query = "insert into s_answer (qnid,pid,answer,centre) values ";
foreach($_POST["fqid"] as $i => $fqid) 
{ 
  // Get values from post.
	
	$fqid = mysql_real_escape_string($fqid);
	$anstype=$_POST["atype"];
	$qfrval=isset($_POST['frval']);
	$qtval=isset($_POST['tval']);
	
  	
	$antype=$anstype[$i];
  	$rval = mysql_real_escape_string($_POST["rval$fqid"][$i]);
  	$frval = mysql_real_escape_string($qfrval[$i]);
	$tval = mysql_real_escape_string($qtval[$i]);
	
	if($antype=='Linear'){ $ans=$rval;}
	else if($antype=='Radio'){ $ans=$frval;}
	else if($antype=='Text'){ $ans=$tval;}

  // Add to database
  $query = $query." ('$fqid','$pid','$rval','$centre') ,";
}
$query = substr($query,0,-1); //remove last char
$result = mysql_query($query);


$sug=isset($_POST["sug"]);
if($sug != ""){
	mysql_query("insert into suggestion (sug,pid,centre) values ('$sug','$pid','$centre') ");
}
	
if($result){
echo ("<SCRIPT LANGUAGE='JavaScript'>
		window.alert('Feedback has been submitted successfully. Thank you for your valuable feedback!')
        window.location.href='home.php'
        </SCRIPT>");
	}
else
{
	
	$error=mysql_error();	
	
	echo "<script type='text/javascript'>alert(\"$error\");</script>";
}
