图片上传PHP

Question

我一直致力于一个比我用它做得更容易的项目。

我制作了一个介于医生和病人之间的整个网站; 我很难上传和检索图片!!

以下是我一直在构建的代码..

<?php session_start();

$un = "xxx";
$pw = "xxx";
$hn = "xxx";
$dbhandle = mysql_connect($hn, $un, $pw) or die("Couldn't connect to the database");
mysql_set_charset('utf8');
$selected = mysql_select_db("dsnnet_login", $dbhandle);
$myusername = $_SESSION['snamed'];


$target_dir = "uploaded/";
$target_file = $target_dir . basename($_FILES["fileToUpload"]["name"]);
$sql = mysql_query("UPDATE docTable set photoname='$target_file' WHERE Username= '$myusername'");
$uploadOk = 1;
$imageFileType = pathinfo($target_file,PATHINFO_EXTENSION);
// Check if image file is a actual image or fake image
if(isset($_POST["submit"])) {
    $check = getimagesize($_FILES["fileToUpload"]["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

// Check file size
if ($_FILES["fileToUpload"]["size"] > 500000) {
    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["fileToUpload"]["tmp_name"], $target_file)) {
        echo "The file ". basename( $_FILES["fileToUpload"]["name"]). " has been uploaded.";
    } else {
        echo "Sorry, there was an error uploading your file.";
    }
}

header("location: docp.php");

?>

和“工作页面”如下：

<?php session_start();

$un = "xxx";
$pw = "xxx";
$hn = "xxx";
$dbhandle = mysql_connect($hn, $un, $pw) or die("Couldn't connect to the database");
mysql_set_charset('utf8');
$selected = mysql_select_db("dsnnet_login", $dbhandle);
$myusername = $_SESSION['snamed'];


$target_dir = "uploaded/";
$target_file = $target_dir . basename($_FILES["fileToUpload"]["name"]);
$sql = mysql_query("UPDATE docTable set photoname='$target_file' WHERE Username= '$myusername'");
$uploadOk = 1;
$imageFileType = pathinfo($target_file,PATHINFO_EXTENSION);
// Check if image file is a actual image or fake image
if(isset($_POST["submit"])) {
    $check = getimagesize($_FILES["fileToUpload"]["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

// Check file size
if ($_FILES["fileToUpload"]["size"] > 500000) {
    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["fileToUpload"]["tmp_name"], $target_file)) {
        echo "The file ". basename( $_FILES["fileToUpload"]["name"]). " has been uploaded.";
    } else {
        echo "Sorry, there was an error uploading your file.";
    }
}

header("location: docp.php");

?>

任何人都可以帮我搞清楚吗？ 我已经尝试了至少4天了.. 我不放弃..我愿意学习......

谢谢你们:) 欢呼声

检查以下

1.tag表格有enctype =＆＃34; multipart / form-data＆＃34;

2.如果不是localhost，文件夹上传必须设置permit 777

Answer 2

我可能知道错误信息会让你陷入困境吗？

在此之前，请检查您的表单enctype属性。您的上传表格必须是：

＆＃13;

＆＃13;

<form action="upload.php" method="post" enctype="multipart/form-data">
    Select image to upload:
    <input type="file" name="fileToUpload" id="fileToUpload">
    <input type="submit" value="Upload Image" name="submit">
</form>

＆＃13;

＆＃13;
