| File Upload script - Need help.
Ive got a file upload script, how can I make it so it gives a random name or ads a few digits on the end instead of saying "change the filename" all the time. Code: <?
//set these variables-----------------------------------------------------------------
$path = "upload/"; //path to your targetfolder after your domain
$max_size = 500000; //maximum filesize
//optionally
$domain = $_SERVER["HTTP_HOST"]; //your domainname - change if necessary like "www.wza.be"
//------------------------------------------------------------------------------------
?>

| heres my script:
it generates a random number between 1 and 9999999999 so you can have a lot of files hosted. |

| heres a script that I threw together:
The form on the page before: Code: <form action="upload.php" method="post" enctype="multipart/form-data" name="form1">
<table width="414" border="0">
<tr>
<td width="158"><span class="style3">File Location: </span></td>
<td width="246"><input name="uploadedfile" type="file" id="uploadedfile"></td>
</tr>
</table>
<p>
<input type="submit" name="Submit" value="Upload File">
</p>
</form>
The php file (upload.php): PHP Code: <?php
// Where the file is going to be placed temporarly
$target_path = "/";
$target_path = $target_path . basename( $_FILES['uploadedfile']['name']);
$_FILES['uploadedfile']['tmp_name']; // temp file
$target_path = "./uploads/";
$oldfile = basename($_FILES['uploadedfile']['name']);
//Check the size
if($_FILES['uploadedfile']['size'] > 500000{
die( "File too large!");
}
//new file name
$newfile = Rand(1,9999999999) . $_FILES['uploadedfile']['name'];
// move the file to the final destination
$target_path = $target_path . basename($newfile);
if(move_uploaded_file($_FILES['uploadedfile']['tmp_name'], $target_path)) {
die( "File Uploaded");
} else{
die("Upload Error");
}
?>
That should work | |

| Another way to do this is. PHP Code: $uniq = substr( md5(uniqid (rand())), 0, 10 );
$ext = strtolower( substr($_FILES['uploadedfile']['name'], -3));
move_uploaded_file($_FILES['uploadedfile']['tmp_name'], $att_path."/".$uniq.".".$ext );
Edited your code: PHP Code: <?php
// Where the file is going to be placed temporarly
$_FILES['uploadedfile']['tmp_name']; // temp file
$target_path = "./uploads/";//Make sure chmodded to 777
$oldfile = basename($_FILES['uploadedfile']['name']);
$allowed_types = array("gif","jpg","png","jpeg","pdf","bmp");
//Check the size
if($_FILES['uploadedfile']['size'] > 500000{
die( "File too large!");
}
//Check file type
if(!in_array(stristr($_FILES['uploadedfile']['name'], "."), "$allowed_types")) {
die( "File type not allowed!");
}
//new file name
$uniq = substr( md5(uniqid (rand())), 0, 10 );
$ext = strtolower( substr($_FILES['uploadedfile']['name'], -3));
move_uploaded_file($_FILES['uploadedfile']['tmp_name'], $path."/".$uniq.".".$ext );
?>
I add file type check code as well
Good Luck! | |
