我是PHP的新手，我需要你的帮助。
这是insert.php文件，插入所有记录.` 此处还添加了文件浏览字段。此字段浏览照片。 Temp_File存储在缩略图文件夹中。我的问题是如何在MySQL数据库中保存这张照片以及如何从dB中检索这张照片以便在view.php中显示。
//这是insert.php
<?php require_once('Connections/db_sms.php'); ?>
<?php if (!isset($_SESSION)) {
session_start();

请帮助我！
答案 0 :(得分：2)
没有理由将图像保存在数据库中。执行此操作的最佳方法是在简单文本字段中记录图像路径。要显示它，只需执行一个简单的查询即可获取图像路径并将其打印到标记中。
答案 1 :(得分：1)
如果你真的需要在MySQL中存储图像（这可能不是一个好主意），你应该使用BLOB列类型。以下是http://www.phpriot.com/articles/images-in-mysql
的示例答案 2 :(得分：0)
不是将图像本身存储在d / b中，最好将图像作为文件存储在磁盘上。将$ target（来自$ target ='thumbnails /'.$ newname;）存储为字符串 - 并在查看时使用检索到的$ target构建am图像标记
答案 3 :(得分：0)
$tmpName = $_FILES['student_photo']['tmp_name'];
// Create the query and insert
// into our database.
$i=rand(0,8888);
$info=pathinfo($_FILES['student_photo']['name']);
$ext=$info['extension'];
$i++;
$newname="pic_".$i.".".$ext;
$target='thumbnails/'.$newname;
move_uploaded_file($_FILES['student_photo']['tmp_name'], $target );
$query = "INSERT INTO tbl_students ";
$query .= "(student_photo) VALUES ('$data')";
$results = mysql_query($query, $link);
//在这些行之间，您应该保存图像名称＆amp;进入数据库的路径。
例如：mysql_query("UPDATE from SET image_path='$image' WHERE id='12')")
您也可以使用INSERT但是，$ name也应该包含路径
$name = thumbnails/$newname id应该是相对的，是您在数据库中发布的帖子的行。
// Print results
print "Thank you, your file has been uploaded.";
在view.php中，您可以在同时显示帖子/文章时简单地显示图像。例如：
$query = "SELECT * FROM students";
$result = mysql_query();
while($row = mysql_fetch_array($result)) {
`echo "
Student Name: $row['student_name'] <br/>
Student Photo: $row['image_path']
"`
}
以上将从数据库中搜索学生沿着图像。
