本文為大家介紹下php上傳圖片到指定位置路徑保存到數(shù)據(jù)庫的具體實現(xiàn)，感興趣的朋友不要錯過

1.conn.php

 
<? 
$host="localhost"; //數(shù)據(jù)庫服務器名稱 
$user="root"; //用戶名 
$pwd="1721"; //密碼 
$conn=mysql_connect($host,$user,$pwd); 
mysql_query("SET 
character_set_connection=gb2312, 
character_set_results=gb2312, 
character_set_client=binary",$conn); 

if ($conn==FALSE) 
{ 
echo "<center>服務器連接失敗！<br>請刷新后重試。</center>"; 
return true; 
} 
$databasename="database";//數(shù)據(jù)庫名稱 

do 
{ 
$con=mysql_select_db($databasename,$conn); 
}while(!$con); 

if ($con==FALSE) 
{ 
echo "<center>打開數(shù)據(jù)庫失??！<br>請刷新后重試。</center>"; 
return true; 
} 

?> 

2.upload.php

復制代碼代碼如下:

 
<?php 
if ($_GET['action'] == "save"){ 
include_once('conn.php'); 
include_once('uploadclass.php'); 
$title=$_POST['title']; 
$pic=$uploadfile; 
if($title == "") 
echo"<Script>window.alert('對不起！你輸入的信息不完整!');history.back()</Script>"; 
$sql="insert into upload(title,pic) values('$title','$pic')"; 
$result=mysql_query($sql,$conn); 
//echo"<Script>window.alert('信息添加成功');location.href='upload.php'</Script>"; 
} 
?> 
<html> 
<head> 
<title>文件上傳實例</title> 
</head> 
<body> 
<form method="post" action="?action=save" enctype="multipart/form-data"> 
<table border=0 cellspacing=0 cellpadding=0 align=center width="100%"> 
<tr> 
<td width=55 height=20 align="center">&nbsp;</TD> 
<td height="16"> 

<table width="48%" height="93" border="0" cellpadding="0" cellspacing="0"> 
<tr> 
<td>標題：</td> 
<td><input name="title" type="text" id="title"></td> 
</tr> 
<tr> 
<td>文件： </td> 
<td><label> 
<input name="file" type="file" value="瀏覽" > 
<input type="hidden" name="MAX_FILE_SIZE" value="2000000"> 
</label></td> 
</tr> 
<tr> 
<td>&nbsp;</td> 
<td><input type="submit" value="上 傳" name="upload"></td> 
</tr> 
</table></td> 
</tr> 
</table> 
</form> 

</body> 
</html> 

3.uploadclass.php

復制代碼代碼如下:

 
<?php 
$uploaddir = "upfiles/";//設置文件保存目錄 注意包含/ 
$type=array("jpg","gif","bmp","jpeg","png");//設置允許上傳文件的類型 
$patch="upload/";//程序所在路徑 

//獲取文件后綴名函數(shù) 
function fileext($filename) 
{ 
return substr(strrchr($filename, '.'), 1); 
} 
//生成隨機文件名函數(shù) 
function random($length) 
{ 
$hash = 'CR-'; 
$chars = 'ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789abcdefghijklmnopqrstuvwxyz'; 
$max = strlen($chars) - 1; 
mt_srand((double)microtime() * 1000000); 
for($i = 0; $i < $length; $i++) 
{ 
$hash .= $chars[mt_rand(0, $max)]; 
} 
return $hash; 
} 

$a=strtolower(fileext($_FILES['file']['name'])); 
//判斷文件類型 
if(!in_array(strtolower(fileext($_FILES['file']['name'])),$type)) 
{ 
$text=implode(",",$type); 
echo "您只能上傳以下類型文件: ",$text,"<br>"; 
} 
//生成目標文件的文件名 
else{ 
$filename=explode(".",$_FILES['file']['name']); 
do 
{ 
$filename[0]=random(10); //設置隨機數(shù)長度 
$name=implode(".",$filename); 
//$name1=$name.".Mcncc"; 
$uploadfile=$uploaddir.$name; 
} 

while(file_exists($uploadfile)); 

if (move_uploaded_file($_FILES['file']['tmp_name'],$uploadfile)) 
{ 
if(is_uploaded_file($_FILES['file']['tmp_name'])) 
{ 

echo "上傳失敗!"; 
} 
else 
{//輸出圖片預覽 
echo "<center>您的文件已經(jīng)上傳完畢 上傳圖片預覽: </center><br><center><img src='$uploadfile'></center>"; 
echo "<br><center><a href='upload.htm'>繼續(xù)上傳</a></center>"; 
} 
} 

} 
?>
