我正在尝试通过插入新图片来更新我的数据库。 我正在运行代码时没有错误，但图片没有进入数据库。以下是我的代码：
<?php
error_reporting( ~E_NOTICE );
require_once 'dbcon.php';
if(isset($_GET['edit_id']) && !empty($_GET['edit_id']))
{
$id = $_GET['edit_id'];
$stmt_edit = $DB_con->prepare('SELECT audit_id, audit_id, descr, correction, status FROM correction WHERE correction_id =:cid');
$stmt_edit->execute(array(':cid'=>$id));
$edit_row = $stmt_edit->fetch(PDO::FETCH_ASSOC);
extract($edit_row);
}
else
{
header("Location: correction.php");
}
if(isset($_POST['btn_save_updates']))
{
$audit_id = $_POST['audit_id'];
$descr = $_POST['descr'];
$status = $_POST['status'];
$imgFile = $_FILES['image']['name'];
$tmp_dir = $_FILES['image']['tmp_name'];
$imgSize = $_FILES['image']['size'];
if($imgFile)
{
$upload_dir = 'images/';
$imgExt = strtolower(pathinfo($imgFile,PATHINFO_EXTENSION));
$valid_extensions = array('jpeg', 'jpg', 'png', 'gif');
$userprofile = rand(1000,1000000).".".$imgExt;
if(in_array($imgExt, $valid_extensions))
{
if($imgSize < 5000000)
{
unlink($upload_dir.$edit_row['correction']);
move_uploaded_file($tmp_dir,$upload_dir.$correction);
}
else
{
$errMSG = "Sorry, Your File Is Too Large To Upload. It Should Be Less Than 5MB.";
}
}
else
{
$errMSG = "Sorry, only JPG, JPEG, PNG & GIF Extension Files Are Allowed.";
}
}
else
{
$correction = $edit_row['correction'];
}
if(!isset($errMSG))
{
$stmt = $DB_con->prepare('UPDATE correction SET correction_id=:cid, audit_id=:aid, descr=:descr, correction=:pic, status=:stat WHERE correction_id=:cid');
$stmt->bindParam(':aid',$audit_id);
$stmt->bindParam(':descr',$descr);
$stmt->bindParam(':pic',$correction);
$stmt->bindParam(':stat',$status);
$stmt->bindParam(':cid',$id);
if($stmt->execute()){
?>
<script>
alert('Successfully Updated...');
window.location.href='correction.php';
</script>
<?php
}
else{
$errMSG = "Sorry. Could Not Be Updated!";
}
}
}

似乎参数的数量在prepare语句中不匹配。
<?php
$stmt = $DB_con->prepare('UPDATE correction SET correction_id=:cid, audit_id=:aid, descr=:descr, correction=:pic, status=:stat WHERE correction_id=:cid2');
$stmt->bindParam(':cid',$id);
$stmt->bindParam(':aid',$audit_id);
$stmt->bindParam(':descr',$descr);
$stmt->bindParam(':pic',$correction);
$stmt->bindParam(':stat',$status);
$stmt->bindParam(':cid2',$id);
