我试图通过路径文件将文件（图像）上传到sql表但我不断收到这些错误＆＃34;未定义的索引：第3行和第24行＆＃34;的图像。我已经在用户页面中定义了图像。我没有使用BLOB，因为它占用了太多空间。在我的sql表中，我只是将image列设置为vachar。我已经检查了xampp中的php.ini文件，上传已打开，最大为2MB上传文件。请帮忙。 TQ
以下是用户页面：
<?php
//useracc-test.php

session_start();
require 'connect-test.php';
include 'upload.php';
if(isset($_POST['username'])){
$userName = $_POST['username'];
$query = "SELECT id, name, username, telno FROM users WHERE username = ?";
$stmt = $conn->prepare($query);
$stmt->bind_param('s', $userName);
$stmt->execute();
$res = $stmt->get_result();
$row = $res->fetch_array();
$_SESSION['id'] = $row['id'];
$_SESSION['name'] = $row['name'];
$_SESSION['username'] = $row['username'];
$_SESSION['telno'] = $row['telno'];

是upload.php文件，我运行上传脚本。
<?php
$target_dir = "uploads/";
$target_file = $target_dir . basename($_FILES["image"]["name"]);
$uploadOk = 1;
$imageFileType = pathinfo($target_file,PATHINFO_EXTENSION);
// Check if image or not
if(isset($_POST["submit"])) {
$check = getimagesize($_FILES["image"]["tmp_name"]);
if($check !== false) {
echo "File is an image - " . $check["mime"] . ".";
$uploadOk = 1;
} else {
echo "File is not an image.";
$uploadOk = 0;
}
}
// Check if file already exists
if (file_exists($target_file)) {
echo "Sorry, file already exists.";
$uploadOk = 0;
}
// Check file size
if ($_FILES["image"]["size"] > 200000) {
echo "Sorry, your file is too large.";
$uploadOk = 0;
}
// Allow certain file formats
if($imageFileType != "jpg" && $imageFileType != "png" && $imageFileType != "jpeg"
&& $imageFileType != "gif" ) {
echo "Sorry, only JPG, JPEG, PNG & GIF files are allowed.";
$uploadOk = 0;
}
// Check if $uploadOk is set to 0 by an error
if ($uploadOk == 0) {
echo "Sorry, your file was not uploaded.";
// if everything is ok, try to upload file
} else {
if (move_uploaded_file($_FILES["image"]["tmp_name"], $target_file)) {
echo "The file ". basename( $_FILES["image"]["name"]). " has been uploaded.";
} else {
echo "Sorry, there was an error uploading your file.";
}
}
?>
我在第3行和第24行获得错误未定义索引。
错误第3行指的是以下;
$target_file = $target_dir . basename($_FILES["image"]["name"]);
错误行24指的是以下;
if ($_FILES["image"]["size"] > 200000) {
答案 0 :(得分：0)
依赖于post参数的所有代码都应该在if isset($_POST['submit'])块内。否则，将不会设置其他$_POST或$_FILE参数。
您遇到的另一个问题是您发布的错误脚本。表格应该说action = "upload.php"。
<?php
if(isset($_POST["submit"])) {
$target_dir = "uploads/";
$target_file = $target_dir . basename($_FILES["image"]["name"]);
$uploadOk = 1;
$imageFileType = pathinfo($target_file,PATHINFO_EXTENSION);
// Check if image or not
$check = getimagesize($_FILES["image"]["tmp_name"]);
if($check !== false) {
echo "File is an image - " . $check["mime"] . ".";
$uploadOk = 1;
} else {
echo "File is not an image.";
$uploadOk = 0;
}
// Check if file already exists
if (file_exists($target_file)) {
echo "Sorry, file already exists.";
$uploadOk = 0;
}
// Check file size
if ($_FILES["image"]["size"] > 200000) {
echo "Sorry, your file is too large.";
$uploadOk = 0;
}
// Allow certain file formats
if($imageFileType != "jpg" && $imageFileType != "png" && $imageFileType != "jpeg"
&& $imageFileType != "gif" ) {
echo "Sorry, only JPG, JPEG, PNG & GIF files are allowed.";
$uploadOk = 0;
}
// Check if $uploadOk is set to 0 by an error
if ($uploadOk == 0) {
echo "Sorry, your file was not uploaded.";
// if everything is ok, try to upload file
} else {
if (move_uploaded_file($_FILES["image"]["tmp_name"], $target_file)) {
echo "The file ". basename( $_FILES["image"]["name"]). " has been uploaded.";
} else {
echo "Sorry, there was an error uploading your file.";
}
}
}
?>
