</label>
<label>
<span>&nbsp;</span>
<input type="button" class="button" value="Send"/>
</label>
</form>


</body>
</html>

和我的php：

<?php
$con = mysqli_connect("", "", "", "");

if (mysqli_connect_errno()) {
echo "Failed to connect to mysqli: ".mysqli_connect_error();
}

$cat = mysqli_real_escape_string($con, $_POST['category']);
$tit = mysqli_real_escape_string($con, $_POST['title']);
$pri = mysqli_real_escape_string($con, $_POST['price']);
$des = mysqli_real_escape_string($con, $_POST['description']);


$sql = "INSERT INTO forsale (Category, Title, Price, Description)        VALUES     ('$cat', '$tit', '$pri', '$des')";

if (!mysqli_query($con,$sql)) {
die('Error: ' . mysqli_error($con));

echo "1 record added";


mysqli_close($con);

?>

现在我缺少的是每个ID上传最多12张此图片的图片，并且能够检索属于eash发布的所有图片

Answer 1

您的代码if (!mysqli_query($con,$sql)) { die('Error: ' . mysqli_error($con));

你错过了这样的结束大括号，不确定这是否是你的问题，但肯定是个问题。

if (!mysqli_query($con,$sql)) {
die('Error: ' . mysqli_error($con));}

将图像上传到MySQL并检索每个表单的正确图像
