圖像保存到文件夾，但路徑未保存在sql

Question

我試圖上傳圖像文件到我的本地文件夾（本地託管）。我設法做到這一點。問題是，我沒有在sql表中看到圖像路徑，包括假設在表中插入的其餘數據。之前，我能夠，之前我搞砸了。我以前對upload.php做了一些小修改。即使我設法將圖像文件上傳到本地文件夾（與我的網頁相同的目錄）。我從早上起就嘗試過，現在是午夜。我也得到一個錯誤 「未定義指數：image..line 106」 - >>

$image = $_POST['image']; 

請help.tq

下面是upload.php的。

<?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(); 


}

根據你原來的職位https://stackoverflow.com/revisions/34568743/1

我們正在處理$_FILES這裏，而不是$_POST。

因此，你需要改變你的$_POST到$_FILES爲$image = $_POST['image'];

參考：

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

Answer 2

1. 請確保您有ENCTYPE = 'multpart /表單數據'形式爲

2. 當插入到數據庫時，請確保您插入的文件路徑即 '$ TARGET_DIR/filetempname'

   $的ImagePath = $ TARGET_DIR/filetempname

3. 請分貝插入只有move_uploaded是成功的。否則的話，安全的原因將是空的。

   if（move_uploaded_file成功）{ //代碼插入到db中。 }

4. 即使使用post方法發佈文件，我們也可以使用$ _FILES變量而不是$ _POST來獲取文件數據。

Answer 3

想要插入圖片的路徑嗎？ 這個變量已經返回到圖像的路徑

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

然後改變這

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

這個

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