【问题描述】：

我有下面的表单和 php 代码，但我的帖子没有出现在我的数据库中，这让我很困惑，因为我不知道问题出在哪里。请帮忙。提前致谢

表单代码是

<html>
<head>
    <title>Insert New Product</title>
<link rel ="stylesheet" href="admin_style.css" />
</head>
<body>
    <form method="post" action="" enctype="multipart/form-data">
        <table width="600" align="center" border="10">

            <tr>
                <td align="center" bgcolor="yellow" colspan="6">    <h1>Insert New Product Here</h1></td>
            </tr>

            <tr>
                <td align="right">Product Name</td>
                <td><input type="text" name="name" size="30"></td>
            </tr>
            <tr>
                <td align="right">Product Price</td>
                <td><input type="text" name="price" size="30"></td>
            </tr>
            <tr>

                <td><input type="file" name="mainimage"></td>
            </tr>
            <tr>

$insert_query = "insert into posts 
(post_name,post_price,post_mainimage,post_suimage1,
post_subimage2,post_image3) values ('$post_name','$post_price','
$post_mainimage','$post_subimage1','$post_subimage2','$post_subimage3')";

if(mysql_query($insert_query)){

echo "<center><h1>POST SUCCESSFUL!</h1></center>";

}


}

【问题讨论】：

connect.php 中有什么？
你能描述得更详细一点吗？您是否收到“发布成功”消息？是不是在这之前就失败了？你有任何错误吗？
检查这个 mysql_query($insert_query) 或 mysql_error() 你会发现查询是否正在运行
@user3619935 将error_reporting(E_ALL);和ini_set('display_errors', 1);放在PHP文件开头打印错误。
"connect.php" 是用来连接数据库的，我每次发帖都没有收到任何错误信息，也没有收到"POST SUCCESSFUL"

【解决方案1】：

解决了最初的问题，包括表中的PRIMARY KEY 和AUTO_INCREMENT 字段id。

下一个问题：不插入新记录且字段为post_nameUNIQUE，尝试使用ON DUPLICATE KEY UPDATE。

$insert_query = "insert into posts 
(post_name,post_price,post_mainimage,post_suimage1,
post_subimage2,post_image3) values ('$post_name','$post_price','
$post_mainimage','$post_subimage1','$post_subimage2','$post_subimage3') 
ON DUPLICATE KEY UPDATE post_price = VALUES(post_price), post_mainimage = VALUES(post_mainimage), 
post_suimage1 = VALUES(post_suimage1), post_suimage2 = VALUES(post_suimage2), post_suimage3 = VALUES(post_suimage3)";
