所以我一直在尝试保存上传到数据库中的文件的路径，但第65行出现错误。似乎问题在于变量$evidence。任何人都可以弄清楚错误是什么。谢谢
<?php
$target_dir = "uploads/";

$uploadOk = 1;

if(isset($_POST["submit"])) {
$check = getimagesize($_FILES["evidence"]["tmp_name"]);

echo "File is an image - " . $check["mime"] . ".";
$uploadOk = 1;

echo "File is not an image.";
$uploadOk = 0;

它会生成错误，因为您正在分配类似输入数据而不是
$_FILES["evidence"]["name"];
//remove thisline $evidence =mysqli_real_escape_string($conn,$_POST['evidence']);
你必须分配这样的证据
$target_file = $target_dir . '/' . basename($_FILES["evidence"]["name"]);
$evidence=$target_file;
现在证据保持图像的地址所以dir。图像现在也是证据。现在它将被上传到数据库 你没有传递数据。 这是错误。 任何问题评论。
供参考，这是用于上传个人资料图片的php脚本，
<?php
if(isset($_POST["submit"]))
{
$target_dir = "profilepic/";
$targetfile=$target_dir.basename($_FILES["fileToUpload"]["name"]);
$uploadOk = 1;
$imageFileType = pathinfo($targetfile,PATHINFO_EXTENSION);
if($imageFileType != "jpg" &&$imageFileType != "JPG" && $imageFileType != "png" && $imageFileType != "PNG" && $imageFileType != "jpeg" && $imageFileType != "JPEG" && $imageFileType != "gif" && $imageFileType != "GIF" )
{
echo "Sorry, only JPG, JPEG, PNG & GIF files are allowed.";
$uploadOk = 0;
}
if ($uploadOk == 0)
{
echo "<small>Sorry, your file was not uploaded.</small>";
}
else
{
if (move_uploaded_file($_FILES["fileToUpload"]["tmp_name"], $targetfile))
{
echo "<small>upload successful</small>";
$imgdir="UPDATE user SET profilepic='$targetfile' WHERE username='$uname';";
$con->query($imgdir);
header("location:profile.php");
}
else
echo "not uploaded";
}
}
?>
用于上传多个文件
<?php
if(isset($_FILES['files'])){
$errors= array();
foreach($_FILES['files']['tmp_name'] as $key => $tmp_name ){
$file_name = $key.$_FILES['files']['name'][$key];
$file_size =$_FILES['files']['size'][$key];
$file_tmp =$_FILES['files']['tmp_name'][$key];
$file_type=$_FILES['files']['type'][$key];
if($file_size > 2097152){
$errors[]='File size must be less than 2 MB';
}
$query="INSERT into upload_data (`USER_ID`,`FILE_NAME`,`FILE_SIZE`,`FILE_TYPE`) VALUES('$user_id','$file_name','$file_size','$file_type'); ";
$desired_dir="user_data";
if(empty($errors)==true){
if(is_dir("$desired_dir/".$file_name)==false){
move_uploaded_file($file_tmp,"user_data/".$file_name);
$status=1;
}else{ //rename the file if another one exist
$new_dir="user_data/".$file_name.time();
rename($file_tmp,$new_dir) ;
}
if($status==1){
mysql_query($query);
}
}else{
print_r($errors);
}
}
if(empty($error)){
echo "Success";
}
}
?>
