<?php 


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

    $stmt = $pdo->prepare('INSERT INTO bikes (model, description, price, manufacturerId) 
          VALUES (:model, :description, :price, :manufacturerId)'); 

    $criteria = [ 
     'model' => $_POST['model'], 
     'description' => $_POST['description'], 
     'price' => $_POST['price'], 
     'manufacturerId' => $_POST['manufacturerId'] 
    ]; 

    $stmt->execute($criteria); 

    if ($_FILES['image']['error'] == 0) { 
     $fileName = $pdo->lastInsertId() . '.jpg'; 
     move_uploaded_file($_FILES['image']['tmp_name'], '../images/bikes/' . $fileName); 
    } 

    echo 'Bike added';

图像名称应该是一个数组也可以使用jquery –

你必须使用文件名阵列和添加'multiple'属性到文件输入标签 'input type =“file”name =“image []”multiple />' –

added 但是当我离开管理员页面图像不可见 – Pactz

要允许从输入文件multiple文件选择会像

<input type="file" name="image" multiple>

要提取选择

print_r($_FILES); // will return you detail of all files in array

输入标签的多个属性中的所有文件并不在互联网支持Explorer 9和更早版本。

您可以一次选择多个文件，但您需要添加多个文件，然后您可以选择这样的文件。

<!doctype html> 
<html lang="en"> 
<head> 
    <meta charset="UTF-8"> 
    <title>Document</title> 
</head> 
<body> 
    <form action="upload.php" method="post" multipart="" enctype="multipart/form-data"> 
     <input type="file" name="img[]" multiple> 
     <input type="submit"> 
    </form> 
</body> 
</html> 

<?php 
echo '<pre>'; 
$img = $_FILES['img']; 

if(!empty($img)) 
{ 
    $img_desc = reArrayFiles($img); 
    print_r($img_desc); 

    foreach($img_desc as $val) 
    { 
     $newname = date('YmdHis',time()).mt_rand().'.jpg'; 
     move_uploaded_file($val['tmp_name'],'./uploads/'.$newname); 
    } 
} 

function reArrayFiles($file) 
{ 
    $file_ary = array(); 
    $file_count = count($file['name']); 
    $file_key = array_keys($file); 

    for($i=0;$i<$file_count;$i++) 
    { 
     foreach($file_key as $val) 
     { 
      $file_ary[$i][$val] = $file[$val][$i]; 
     } 
    } 
    return $file_ary; 
}
