Question

我正在尝试将图片文件上传到我的本地文件夹（本地托管）。我设法做到了。问题是，我没有看到sql表中的图像路径，包括假设要插入表中的其余数据。以前我能够，在我搞砸之前。我之前对upload.php做了一些小改动。即使我设法将图像文件上传到本地文件夹（与我的页面相同的目录）。我从早上开始尝试这个，现在是午夜。我也收到错误“Undefined index：image..line 106” - ＆gt;＆gt;

$image = $_POST['image'];

请help.tq

以下是upload.php。

   <?php


//echo var_dump($_POST);
//echo var_dump($_FILES);

session_start();



require 'connect-test.php';




if(isset($_POST["submit"])) {




    $id = $_POST['id'];
    $name2 = $_POST['name2'];
    $color2 = $_POST['color2'];
    $hobby2 = $_POST['hobby2'];
    $radiobtn = $_POST['radiobtn'];
    $image = $_FILE['image'];







        $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"] > 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["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.";
    }
}





    $stmt = $conn->prepare("INSERT INTO useradvert (id,name2,color2,hobby2,radiobtn,image) VALUES (?,?,?,?,?,?)");
    $stmt->bind_param("isssss",$id,$name2,$color2,$hobby2,$radiobtn,$target_file);
    $stmt->execute();


}

Answer 1

根据您的原始帖子https://stackoverflow.com/revisions/34568743/1

我们在这里处理的是$_FILES，而不是$_POST。

因此，您需要将$_POST改为$_FILES $image = $_POST['image'];

参考：

http://php.net/manual/en/features.file-upload.post-method.php

Answer 2

您想要插入图片的路径吗？此变量已返回图像的路径

$target_file = $target_dir . basename($_FILES["image"]["name"]);

然后改变这个

$stmt->bind_param("isssss",$id,$name2,$color2,$hobby2,$radiobtn,$image);

到这个

$stmt->bind_param("isssss",$id,$name2,$color2,$hobby2,$radiobtn,$target_file);

Answer 3

确保您有enctype =＆＃39; multpart / form-data＆＃39;格式为
插入数据库时，请确保插入文件路径，即$ target_dir / filetempname＆＃39;

$ imagepath = $ target_dir / filetempname
仅当move_uploaded成功时才请在db中插入。否则事情将是空的安全原因。

if（move_uploaded_file成功）{ //要在db中插入的代码。 }
我们使用$ _FILES变量而不是$ _POST获取文件数据，即使文件是使用post方法发布的。

图像保存到文件夹但路径未保存在sql中
