    </head>
<body>
    <form method="post" action="insert_post_1.php"        enctype="multipart/form-data">
    <table width="600" align="center" border="10">
        <tr>
            <td align="center" bgcolor="yellow" colspan="6">
                <h1>Insert New Post Here</h1>
            </td>

        <tr>
            <td align="right">Post Title:</td>
            <td><input type="text" name="title" size="30"></td>
        </tr>
        <tr>
            <td align="right">Post Author:</td>
            <td><input type="text" name="author" size="30"></td>
        </tr>
        <tr>

            <td><input type="text" name="keywords" size="30"></td>
        </tr>
        <tr>
            <td align="right">Post Image:</td>
            <td><input type="file" name="image" size="30"></td>
        </tr>
        <tr>
            <td align="right">Post Content:</td>
            <td><textarea name="content" cols="30" rows="25"></textarea></td>
        </tr>
        <tr>
            <td align="center" colspan="6"><input type="submit" name="submit" value="Publish Now"></td>
        </tr>

    </table>
    </form>
</body>
</html>

/ html没有问题它工作得很好但是使用这个PHP代码我无法检测到问题。单击“发布”按钮时，不会将数据插入数据库 /

    if($post_title == '' or $post_keywords == '' or $post_author == '' or $post_content == ''){
    echo "<script>alert('Any of the fields is empty')</script>";
    exit();
    }
    else{
    move_uploaded_file($post_temp, "images/$post_image");
/*this part of code is not running and hence unable to insert data to database*/    
    $insert_query = "INSERT INTO "
            . "posts (`post_id`, `post_title`, `post_date`, `post_author`, `post_image`, `post_keywords`, `post_content`)"
            . " VALUES (NULL, $post_title, $post_date, $post_author, $post_image, $post_keywords, $post_content)";

    if(mysql_query($insert_query)){
        echo "<center><h1>Post Published Successfully</h1></center>";
    }
    }
}
?>

Answer 1

如果您仍想使用mysql扩展，请注释此块

if(mysql_query($insert_query)){
    echo "<center><h1>Post Published Successfully</h1></center>";
}

并在下方添加

mysql_query($insert_query) or die(mysql_error());
echo "<center><h1>Post Published Successfully</h1></center>";

以查看错误

Answer 2

首先，您需要查看THIS文档：

mysql_query已被删除。使用PDO或mysqli。

检查mysql中的错误：

try{
   // Run your query:
}
catch(Exception $e){
   echo $e->getMessage();
}

无法将数据插入mysql无错误显示
