♫ UPLOAD FILE IN DB:
first of all create a new directory named "upload"
then, create a database and table with this code (here db creation code is not present as i created db manualy with db creation code):
<?php
$dbc=mysql_connect("localhost","root","") or die("error in server conn.");
$dbname="databasename2";
$dbs=mysql_select_db($dbname,$dbc) or die("error in db selection");
$sql="CREATE TABLE table1 (
id int(10) not null auto_increment,
name varchar(55) not null,
type varchar(55) not null,
size int(55) null,
path longblob,
primary key (id)
)";
mysql_query($sql) or die(mysql_error());
mysql_close($dbc);
?>
after that,
write the following php code and save it as upload.php
<form method="post" enctype="multipart/form-data">
<table width="350" border="0" cellpadding="1" cellspacing="1" class="box">
<tr>
<td width="246">
<input type="hidden" name="MAX_FILE_SIZE" value="16777216">
vinput name="userfile" type="file" id="userfile">
</td>
<td width="80"><input name="upload" type="submit" class="box" id="upload" value=" Upload "></td>
</tr>
</table>
</form>
<?php
$dbname="databasename2";
$dbc=mysql_connect("localhost","root","") or die("error in db connection");
$dbs=mysql_select_db($dbname,$dbc) or die("error in db selection");
$uploadDir = "upload/";
if(isset($_POST['upload']))
{
$fileName = $_FILES['userfile']['name'];
$tmpName = $_FILES['userfile']['tmp_name'];
$fileSize = $_FILES['userfile']['size'];
$fileType = $_FILES['userfile']['type'];
$filePath = $uploadDir . $fileName;
$result = move_uploaded_file($tmpName, $filePath);
if (!$result) {
echo "Error uploading file";
exit;
}
if(!get_magic_quotes_gpc())
{
$fileName = addslashes($fileName);
$filePath = addslashes($filePath);
}
$query = "INSERT INTO table1 (name, size, type, path ) ".
"VALUES ('$fileName', '$fileSize', '$fileType', '$filePath')";
mysql_query($query) or die('Error, query failed : ' . mysql_error());
echo "<br>Files successfully uploaded<br>";
}
?>
♫ DOWNLOAD FILE FROM DB
♫ DOWNLOAD FILE FROM DB:
we need two php file (a) file_download.php and (b) file_download2.php (make sure you have 'upload' directory from where the files would be downloaded)
(a) file_download.php
<?php
$dbh = mysql_connect("localhost","root","") or die("There was a problem with the database connection.");
$dbs = mysql_select_db("databasename2", $dbh) or die("There was a problem selecting the categories.");
$result=mysql_query("SELECT * FROM table1 ");
echo "id \n\n";
echo "name \n\n";
echo "size(byte)\n\n";
echo "<br><br>";
while($row=mysql_fetch_array($result))
{
echo "$row[id]"."\n\n\n\n";
echo "$row[name]"."\n\n\n\n";
echo "$row[size]";
echo " <td>" . stripslashes($row->description) . "</td>\n";
echo " <td>( <a href='file_download2.php?id=$row[id]'>Download</a> )</td>\n";
echo " </tr>";
echo "<br><br>";
}
mysql_free_result($result);
?>
(b) file_download2.php
<?php
$dbc=mysql_connect("localhost","root","") or die("error in db connection");
$dbs=mysql_select_db("databasename2",$dbc) or die("error in db selection");
if(isset($_GET['id']))
{
$id = $_GET['id'];
$query = "SELECT name, type, size, path FROM table1 WHERE id = '$id'";
$result = mysql_query($query) or die('Error, query failed');
list($name, $type, $size, $filePath) = mysql_fetch_array($result);
header("Content-length: $size");
header("Content-type: $type");
header("Content-Disposition: attachment; filename=$name");
header("Content-Description: PHP Generated Data");
readfile($filePath);
exit;
}
?>
( note: i was not able to download files with associated format with the above code,
after download, rename the file with its fomat, like- after download,
the audio file would be 'strings' and you have to rename it as 'strings.mp3', thats all )
