使用PHP在产品详细信息页面上将多个图像添加到一个产品
我正在使用PHP / MYSQL开发一个基本的电子商务网站。我只需要知道如何上传产品的多个图像，然后以这种格式在Example of what I'm trying to implement
的产品详情页面上显示它们 
我一直试图弄清楚如何显示这些图像（1个产品的多个图像）。我真的不明白它应该如何运作！所以任何关于简单术语的建议都会受到赞赏。
目前，我每个产品只能上传1张图片。 这是我到目前为止（每个产品1张图片），
对于产品类页面
<?php
class Product{
private $db;
private $fm;
public function __construct(){
$this->db = new Database();
$this->fm = new Format();
}
public function productInsert($data, $file){
$productName = mysqli_real_escape_string($this->db->link, $data['productName']);
$catId = mysqli_real_escape_string($this->db->link, $data['catId']);
$body = mysqli_real_escape_string($this->db->link, $data['body']);
$price = mysqli_real_escape_string($this->db->link, $data['price']);
$type = mysqli_real_escape_string($this->db->link, $data['type']);
$town = mysqli_real_escape_string($this->db->link, $data['town']);
$quantity = mysqli_real_escape_string($this->db->link, $data['quantity']);
$email = mysqli_real_escape_string($this->db->link, $data['email']);
$phone = mysqli_real_escape_string($this->db->link, $data['phone']);
$contactName = mysqli_real_escape_string($this->db->link, $data['contactName']);
$permited = array('jpg', 'jpeg', 'png', 'gif');
$file_name = $file['image']['name'];
$file_size = $file['image']['size'];
$file_temp = $file['image']['tmp_name'];
$div = explode('.', $file_name);
$file_ext = strtolower(end($div));
$unique_image = substr(md5(time()), 0, 10).'.'.$file_ext;
$uploaded_image = "../uploads/".$unique_image;
if($productName == "" || $catId == "" || $price == "" || $file_name == "" || $town == "" || $quantity == "" || $email == "" || $phone == "" || $contactName == ""){
$msg = "<span class='error'>Fields must not be empty!</span>";
return $msg;
} elseif ($file_size >1048567) {
echo "<span class='error'>Image Size should be less then 1MB!
</span>";
} elseif (in_array($file_ext, $permited) === false) {
echo "<span class='error'>You can upload only:-".implode(', ', $permited)."</span>";
} else{
move_uploaded_file($file_temp, $uploaded_image);
$query = "INSERT INTO products(productName, catId, body, price, image, type, town, quantity, email, phone, contactName) VALUES('$productName','$catId','$body','$price','$uploaded_image', '$type','$town','$quantity','$email','$phone','$contactName')";
$inserted_row = $this->db->insert($query);
if($inserted_row){
$msg = "<span class='success'> Your Offer is Added Successfully. </span>";
return $msg;
} else{
$msg = "<span class='error'> Sorry! Your offer is not added! Try again later. </span>";
return $msg;
}
}
}
对于添加产品页面
<?php
$product = new Product();
if($_SERVER['REQUEST_METHOD'] == 'POST' && isset($_POST['submit'])){
$insertProduct = $product->productInsert($_POST, $_FILES);
}
?>
<form action="" method="post" enctype='multipart/form-data'>

<?php
$cat = new Category();
$getCat = $cat->getAllCat();
if($getCat){
while($result = $getCat->fetch_assoc()){
?>
<option value="<?php echo $result['catId'];?>"><?php echo $result['catName'];?></option>
<?php } } ?>

有人可以帮助我修改此代码，以便能够为每件产品上传多张图片，并能够在产品详情页面上检索这些图片吗？

答案 0 :(得分：0)
要上传多张图片，您可以使用
<input type="file" name="image[]" multiple>
并使用mysql_fetch_array()方法
$sql="SELECT *
FROM tbl_image
WHERE productId= 1 ";
$query=mysql_query($sql);
while($row=mysql_fetch_array($query))
{
$image=$row ['photo'];
echo '<img src="path/'.$image.'" width="360" height="150">';
}
