多圖像上傳

Question

我正在創建圖庫網站，並且希望僅使用PHP和MYSQLI創建一個多圖像上傳器...我不擅長編碼，因此本網站上的多圖像上傳的其他示例沒有不爲我工作。

以下是根據當前用戶會話將數據發佈到數據庫中的工作代碼。

HTML：

<form action="upload.php" method="post" enctype="multipart/form-data"> 
<label for="image">Select a file:</label> 
<input type="file" name="image[]" id="image" multiple='multiple' /> 
<br /><br> 
<label for="picname">Title:</label> 
<input type="text" name="picname" id="picname" /> 
<br /><br> 
<label for="picdesc">Description:</label> 
<input type="text" name="picdesc" id="picdesc" /> 
<br /><br> 
<label for="piccat">Category:</label> 
<select name="piccat" id="piccat"> 
<option value="--"></option> 
<option value="animation">Animation</option> 
<option value="illustration">Illustration</option> 
<option value="photography">Photography</option> 
</select> 
<br /><br> 
<input type="submit" name="submit" value="Submit" /> 
</form> 

PHP &的mysqli：

<?php 
$path = "images/projects/"; 
include("check.php"); 

if (isset($_POST["submit"])) { 
     $image = $_FILES["image"]["tmp_name"]; 
     $imageName = $_FILES["image"]["name"]; 
     $imageSize = $_FILES["image"]["size"]; 
     $imageType = $_FILES["image"]["type"]; 
     $imageTitle = $_POST["picname"]; 
     $imageDescription = $_POST["picdesc"]; 
     $imageCategory = $_POST["piccat"]; 
     $len = count($image); 
     $path = $path . $imageName; 

     $query = $db -> prepare("INSERT INTO images (user_id, image, description, type, title, size, category) 
     VALUES (?, ?, ?, ?, ?, ?, ?)"); 
     $query -> bind_param('issssis', $_SESSION['user_id'], $imageName, $imageDescription, $imageType, $imageTitle, $imageSize, $imageCategory); 
     $query -> execute(); 
     $query -> close();   

    if ($imageName){ 
      move_uploaded_file($image, $path); 
      } 
} 
?> 

它工作正常，但只能上傳一個圖片。如何選擇多個圖像並一次上傳所有圖像？

Answer 1

使用這一個

<?php 
$path = "images/projects/"; 
include("check.php"); 
if (isset($_POST["submit"])) { 
    for ($i = 0; $i < count($_FILES["image"]["name"]); $i++) { 
    $image = $_FILES["image"]["tmp_name"][$i]; 
    $imageName = $_FILES["image"]["name"][$i]; 
    $imageSize = $_FILES["image"]["size"][$i]; 
    $imageType = $_FILES["image"]["type"][$i]; 
    $imageTitle = $_POST["picname"]; 
    $imageDescription = $_POST["picdesc"]; 
    $imageCategory = $_POST["piccat"]; 
    $path = $path . $imageName; 

    $query = $db -> prepare("INSERT INTO images (user_id, image, description, type, title, size, category) 
    VALUES (?, ?, ?, ?, ?, ?, ?)"); 
    $query -> bind_param('issssis', $_SESSION['user_id'], $imageName, $imageDescription, $imageType, $imageTitle, $imageSize, $imageCategory); 
    $query -> execute(); 
    $query -> close();   

if ($imageName){ 
     move_uploaded_file($image, $path); 
     } 
} 
} 
?>
