最近作了一个图片上传到mysql中，可是出现了一些问题，就是图片能够上传，却不可以显示图片，请各位高手们帮帮忙： php

一、我建了一个数据库 html

二、index.php文件 mysql

}else{ 数据库

?> post

<td width="500" height="180">
<table width="236" height="185" border="0" cellpadding="0" cellspacing="0">
<tr>
<td height="160" colspan="2">
<div align="center">
<img src="image.php?recid=<?php echo $info[id];?>" width="225" height="160">
</div>
</td>
</tr>
<tr>
<td width="106" height="25"> 图片名称：<?php echo $info[tpmc];?></td>
<td width="130">上传时间： <?php echo $info[scsj];?></td>
</tr>
</table>
</td>
<?php
}
$i++;
}
?>
</tr>
</table>
<table width="500" border="0" align="center" cellpadding="0" cellspacing="0">
<tr>
<td width="52%">  页次：<?php echo $page;?>/<?php echo $page_count;?>
页记录：<?php echo $message_count;?>条 </td>
<td align="right" class="hongse01">
<?php
if($page!=1)
{
echo "<a href=index.php?page=1>首页</a> ";
echo "<a href=index.php?page=".($page-1).">上一页</a> ";
}
if($page<$page_count)
{
echo "<a href=index.php?page=".($page+1).">下一页</a> ";
echo "<a href=index.php?page=".$page_count.">尾页</a>";
}
}
?>
</td>
</tr>
</table> fetch

三、图片提交文件：tptj.php ui

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>无标题文档</title>
</head>

<body>
<?php
include("../conn/conn.php"); //连接数据源
$connection = mysql_connect($db_host, $db_username, $db_password);
if(!$connection)
{
die("Could not connect to the database: <br/>". mysql_error());
}
else
{
echo "Connect successful!<br/>";
}
//select the database
$db_select=mysql_select_db($db_database);
if(!$db_select)
{
die("Could not select the database:<br/>". mysql_error());
}
else
{
echo "select successful<br/>";
}
$tpmc = $_POST["tpmc"];
$file=$_FILES["filepath"];
$sc=$_POST["sc"];

if($sc!=="")
{

$tpmc=htmlspecialchars($tpmc); //将图片名称中的特殊字符转换成HTML格式
$tpmc=str_replace("\n","<br>",$tpmc); //将图片名称中的回车符以自动换行符取代
$tpmc=str_replace(""," ",$tpmc); //将图片名称中的空格以“ "取代
$scsj=date("y;m;d"); //设置图片的上传时间
$fp=fopen($file['tmp_name'],"r"); //以只读方式打开文件
//if( $fp==
$file=addslashes(fread($fp,$file['size'])); //将文件中的引号部分加上反斜线
header("Content-Type:image/jpeg");
$query="insert into tb_tpsc(tpmc,file,scsj) values ('".$tpmc."','".$file."','".$scsj."')";//建立插入图片数据的SQL语句
$result= mysql_query($query);
//echo "<meta http-equiv=\"refresh\" content=\"1; url=index.php\">图片上传成功，请稍等...";

}
mysql_close();
?>
</body>
</html>
this

四、image.php url

<?php

header("Content-Type:image/jpeg"); include "../conn/conn.php"; $connection = mysql_connect($db_host, $db_username, $db_password); if(!$connection) { die("Could not connect to the database: <br/>". mysql_error()); } else { echo "Connect successful2!<br/>"; } //select the database $db_select=mysql_select_db($db_database); if(!$db_select) { die("Could not select the database:<br/>". mysql_error()); } else { echo "select successful2<br/>"; } $query="select * from tb_tpsc where id=".$recid; //查询指定ID的图片信息 $result=mysql_query($query); if(!$result) die("error:mysql query"); $num=mysql_num_rows($result); if($num<1) die("error:no this recorder"); //$data = mysql_result($result,0,'file'); //echo $data; //输出图片信息 $row=mysql_fetch_object($result); echo $row->file; mysql_close(); ?>
