HTML表单和PHP查询不向MySQL数据库提交数据

标签： php mysql

下面是一个应该将信息提交到MySQL数据库的表单。

下面的提交表单及其相应的查询文件无效。我填写所有字段，然后单击“提交”，我没有收到任何错误消息。

在submit2a.php上，我有mysql_connect() or die(mysql_error());和mysql_select_db() or die(mysql_error());并且我没有收到错误，因此我认为它正在连接到MySQL。

但是当我检查MySQL数据库时，我添加的新信息不存在。

有没有人在下面的代码中看到任何明显的错误？

提前致谢，

在第一个实例中，我觉得你在大多数语句中都没有调用“mysql_query”。即$ queryimage1，queryimage2，......

当前声明：

$queryimage1 = sprintf(
            "insert into images (NULL, submissionid, filename, mime_type, file_size, file_data)
                values ('%s', '%s', '%s', %d, '%s')",
            $submissionid,
            mysql_real_escape_string($image1['name']),
            mysql_real_escape_string($info1['mime']),
            $image1['size'],
            mysql_real_escape_string(
                file_get_contents($image1['tmp_name'])
            )
        )or die(mysql_error());

将是：

$queryimage1 = mysql_query(sprintf(
            "insert into images (NULL, submissionid, filename, mime_type, file_size, file_data)
                values ('%s', '%s', '%s', %d, '%s')",
            $submissionid,
            mysql_real_escape_string($image1['name']),
            mysql_real_escape_string($info1['mime']),
            $image1['size'],
            mysql_real_escape_string(
                file_get_contents($image1['tmp_name'])
            )
        ))or die(mysql_error());

你应该使用MYSQLI或MYSQLI_PREPARE！
