上传图像到服务器

问题描述：

我想知道如何将图像上传到服务器目录？有人可以教我，因为我也想更多地了解这件事。这是因为我不熟悉这种编码。我试图将图像上传到数据库中，并且它可以正常工作，但图像没有进入服务器。只有文件名插入到数据库中。请帮帮我！感谢上传图像到服务器

<?php 
include("db.php"); 
$id = $_POST['id']; 
$bg = trim($_POST['com_bg']); 
$ben = trim($_POST['com_benefit']); 
$rem = trim($_POST['com_remark']); 
//print_r($_FILES); 
//echo "<br><br>"; 
$name = $_FILES['file']['name']; 
$format = substr($name, strpos($name, '.'), strlen($name) - 1); 

//if they DID upload a file... 
if($_FILES['file']['name']) 
{ 
//Check if the file is JPEG,PNG or GIF image 
if(($_FILES["file"]["type"] == "image/jpeg")||($_FILES["file"]["type"] == "image/png")||($_FILES["file"]["type"] == "image/gif")) 
{ 
    $newname = dirname(__FILE__).'/upload/'.$name; 
    //Check if the file with the same name is already exists on the server 
    if (!file_exists($newname)) 
    { 
     //move it to where we want it to be 
     move_uploaded_file($_FILES["file"]["tmp_name"],"upload/" .  $_FILES["file"]["name"]); 
     $sql= "UPDATE company SET com_logo='$name' WHERE com_idx = '$id'"; 
     $result = mysql_query($sql); 
    } 
    else 
    { 
     header("Location: profile_2.php?note=1"); 
     //echo "Error: File ".$_FILES["file"]["name"]." already exists"; 
    } 
} 
else 
{ 
    header("Location: profile_2.php?note=2"); 
    //echo 'wrong extension '; 
} 

} 

$sql= "UPDATE company SET com_intro='$bg',com_description='',com_benefit='$ben',com_remark='$rem' WHERE com_idx = '$id'"; 
$result = mysql_query($sql); 
header("Location: profile_2.php"); 

?>

答

首先对所有你应该在php.ini文件中检查这些配置

file_uploads 
upload_max_filesize 
max_input_time 
memory_limit 
max_execution_time 
post_max_size

其次确保该文件夹中yopu要上传的文件必须存在，应该拨出权限

建议避免使用mysql_ *函数学习PDO或mysqli的

看到http://www.radinks.com/upload/config.php – alwaysLearn

我在哪里可以找到这个php.ini文件？ –

好的。我发现它嘿 –

试试这个例子

<header> 
    <?php 
    function UploadOne($fname) 
    { 
    $uploaddir = 'uploadedfiles/'; 
    if (is_uploaded_file($fname['tmp_name'])) 
    { 
    $filname = basename($fname['name']); 
    $uploadfile = $uploaddir . basename($fname['name']); 
    if (move_uploaded_file ($fname['tmp_name'], $uploadfile)) 
    $res = "File " . $filname . " was successfully uploaded and stored.<br>"; 
    else 
    $res = "Could not move ".$fname['tmp_name']." to ".$uploadfile."<br>"; 
    } 
    else 
    $res = "File ".$fname['name']." failed to upload."; 
    return ($res); 
    } 
    ?> 
    </header> 
    <body> 
    <?php 
    if ($_FILES['picture']['name'] != "") 
    { 
    $res = UploadOne($_FILES['picture']); 
    $filname = $_FILES['picture']['name']; 
    echo ($res); 
    } 
    ?> 
    <h1>UPLOADING FILES</h1> 
    <form name="fupload" enctype="multipart/form-data" action="upfiles.php" method="post"> 
    <input type="file" name="picture" /> 
    <input type="submit" value="Submit" /> 
    </form> 
    </body>

其实代码是正确的，但我只是发现我的文件夹，我需要将其更改为777而不是755.哈哈对不起！ –

哈哈伟人没问题 –
