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($con);
?>
现在我缺少的是每个ID上传最多12张此图片的图片，并且能够检索属于eash发布的所有图片
答案 0 :(得分：0)
您的代码if (!mysqli_query($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));}
