使用PHP上传文件并将路径添加到MySQL数据库

Question

Upload.php：

<?php

//This is the directory where images will be saved
$target = "pics";
$target = $target . basename( $_FILES['Filename']['name']);

//This gets all the other information from the form
$Filename=$_POST['Filename'];
$Description=$_POST['Description'];
$pic=($_FILES['Filename']['name']);


// Connects to your Database
mysql_connect("localhost", "root", "") or die(mysql_error()) ;
mysql_select_db("altabotanikk") or die(mysql_error()) ;

//Writes the information to the database
mysql_query("INSERT INTO picture (Filename,Description)
VALUES ('$Filename', '$Description')") ;

//Writes the Filename to the server
if(move_uploaded_file($_FILES['Filename']['tmp_name'], $target)) {
    //Tells you if its all ok
    echo "The file ". basename( $_FILES['uploadedfile']['Filename']). " has been uploaded, and your information has been added to the directory";
} else {
    //Gives and error if its not
    echo "Sorry, there was a problem uploading your file.";
}
?>

这是表格（在单独的文件中）：

<form method="post" action="upload.php" enctype="multipart/form-data">
    <p>Photo:</p>
    <input type="file" name="Filename"> 
    <p>Description</p>
    <textarea rows="10" cols="35" name="Description"></textarea>
    <br/>
    <input TYPE="submit" name="upload" value="Add"/>
</form>

错误是

 Undefined index: Filename on Line 17

（$ Filename = $ _ POST [‘Filename’];）

和

Undefined index: uploadedfile on Line 35

（回显“文件“。basename（$ _FILES [‘uploadedfile’]
[‘Filename’]）。”已经上传，并且您的信息已添加到目录中“；）

echo"<pre>".print_r($_FILES,true)."</pre>";

给我：

Array
(
    [Filename] => Array
        (
            [name] => Laserkanon.jpg
            [type] => image/jpeg
            [tmp_name] => C:\WampServer\tmp\php11D4.tmp
            [error] => 0
            [size] => 41813
        )

)

首先，您应该使用它print_r($_FILES)进行调试，然后查看其中包含的内容。：

您uploads.php将看起来像：

//This is the directory where images will be saved
$target = "pics/";
$target = $target . basename( $_FILES['Filename']['name']);

//This gets all the other information from the form
$Filename=basename( $_FILES['Filename']['name']);
$Description=$_POST['Description'];


//Writes the Filename to the server
if(move_uploaded_file($_FILES['Filename']['tmp_name'], $target)) {
    //Tells you if its all ok
    echo "The file ". basename( $_FILES['Filename']['name']). " has been uploaded, and your information has been added to the directory";
    // Connects to your Database
    mysql_connect("localhost", "root", "") or die(mysql_error()) ;
    mysql_select_db("altabotanikk") or die(mysql_error()) ;

    //Writes the information to the database
    mysql_query("INSERT INTO picture (Filename,Description)
    VALUES ('$Filename', '$Description')") ;
} else {
    //Gives and error if its not
    echo "Sorry, there was a problem uploading your file.";
}

由于这是旧帖子，目前强烈建议在php中使用mysqli或pdo代替mysql_函数
