Question

我已经创建了一个表单，用户填写并上传附带的文件，但每当我点击提交按钮时，我会在输入文件字段中获得注意：未定义的索引，而不是其他的

我的，代码似乎很好，但我不知道为什么我得到这个。我是个菜鸟，任何人都可以帮助我！

我的PHP代码，

<?php
ini_set('error_reporting', E_ALL);
ini_set('display_errors', 'On');
include("config.php");
$name =$_POST["u_n"];
$pass =$_POST["u_p"];
$type =$_POST["u_t"];
$hobb =implode(',',$_POST["u_h"]);
$ctry =$_POST['u_c'];
$fav =implode(',',$_POST['u_f']);
    $file = $_FILES['res'];
    $file_name = $file['name'];
    $file_type = $file ['type'];
    $file_size = $file ['size'];
    $file_path = $file ['tmp_name'];
    move_uploaded_file ($file_path,'Uploads/'.$file_name);
    $img =$_FILES['img'];
    $img_count = count($img["name"]);
    $arr =[];
    for($i=0;$i<$img_count;$i++){
        $name= $img["name"][$i];
        $temp= $img["tmp_name"][$i];
        $type= $img["type"][$i];
        $size= $img["size"][$i];
        $error= $img["error"][$i];
        move_uploaded_file ($temp,'Uploads/'.$name);
        $arr[$i]= $name;
    }
$count= count($arr);
for($i=0; $i<4; $i++){
    if($i>$count-1){
        $arr[$i]='';
    }        
}
$query = "INSERT INTO users2 (U_name, U_pass, U_type, U_hob, U_img, img2, img3, img4, U_res, U_fav, U_ctry)
VALUES('$name', '$pass', '$type', '$hobb', '$arr[0]', '$arr[1]', '$arr[2]', '$arr[3]', '$file_name', '$fav', '$ctry')";
if(mysqli_query($db, $query)){
    echo "uploaded";
}
else{
    echo "not uploaded";
}?>

我的HTML代码，

在php中处理文件上传时，请添加enctype属性，如

<form enctype="multipart/form-data" action="../../panel/database_uploader3.php" method= "post">

您正在使用支持预准备语句的api。请用它

注意：php中的未定义索引甚至我定义索引正确
