這裏我試圖上傳圖像到目錄並添加數據庫中的路徑。 在這裏，我首先添加一些產品詳細信息，並嘗試上傳圖像以上傳目錄並將上傳的圖像路徑添加到數據庫中。如何在php中將圖像上傳到數據庫？
這裏是我做了什麼：
<?php
/* Attempt MySQL server connection. Assuming you are running MySQL
server with default setting (user 'root' with no password) */
$link = mysqli_connect("localhost", "root", "", "wan_products_box");
// Check connection
if($link === false){
die("ERROR: Could not connect. " . mysqli_connect_error());
}
// Escape user inputs for security
$product_name = mysqli_real_escape_string($link, $_POST['product_name']);
$product_category = mysqli_real_escape_string($link, $_POST['product_category']);
$product_price = mysqli_real_escape_string($link, $_POST['product_price']);
$pro_url = mysqli_real_escape_string($link, $_POST['pro_url']);
$co_owners = mysqli_real_escape_string($link, $_POST['co_owners']);
// attempt insert query execution
$sql = "INSERT INTO product_list (product_name, product_category, product_price,product_referrence_URL,product_co_owners) VALUES ('$product_name', '$product_category', '$product_price', '$pro_url', '$co_owners')";
if(mysqli_query($link, $sql)){
echo "New product created.";
} else{
echo "ERROR: Could not able to execute $sql. " . mysqli_error($link);
}
//image upload code
if($_POST)
{
if($_FILES["file"]["error"] > 0)
{
echo "Return Code: " . $_FILES["file"]["error"] . "<br />";
}
else
{
if(file_exists("uploaded_images/" . $_FILES["file"]["name"]))
{
echo $_FILES["file"]["name"] . " already exists. ";
}
else
{
if(move_uploaded_file($_FILES["file"]["tmp_name"],"uploaded_images/" . $_FILES["file"]["name"]))
{
$query_image = "INSERT INTO product_list (product_image_url) values ('".$_FILES['file']['name']."')";
if(mysql_query($query_image))
{
echo "Stored in: " . "uploaded_images/" . $_FILES["file"]["name"];
}
else
{
echo 'Unable to store';
}
}
}
}
}
mysqli_close($link);
?>
這是我的HTML表單：

的數據插入到數據庫中，但圖片上傳部分是不會發生... 如何我可以這樣做嗎？我如何修改代碼上傳圖像到數據庫並添加數據庫路徑？
當我運行這個輸出我得到的是
New product created.

你可以顯示錶格嗎？聽起來像你沒有一個名爲「文件」的文件輸入 – rjdown
你的表單失敗了，爲什麼？因爲...沒有有效的enctype和/或缺少名稱屬性 –
混合'mysql'和'mysqli' – Saty
