Sunny’s Question:

sunnysunny

I am new in PHP. I have an idea. Can i copy a recoed of table and save it with different id in same table?

For example i have a web form with different fields. I use that form to store data in database. Now i have a page where i display that record and use CRUD operations. When user click on Edit Button it goes on Form where he see a Button of Create copy. When user click on Create Copy button it just begin to start making a copy of selected data and store same data with different id?

Here is a simple way. You can have multiple submit buttons. Like

<input type="submit" name="submit" value="Edit" />
<input type="submit" name="submit" value="Make a copy" />

When this forms get submitted, you can check which submit button was pressed by asserting with $_POST['submit'] or $_GET['submit'] if you method is GET.

For example:

if($_POST['submit'] == 'Make a copy') {
    $action = "copy";
} elseif($_POST['submit'] == 'Edit') {
    $action = "edit";
}

Using that you can know what the user wanted to do. Since you already have the data, just pass those to your function which creates a new record without the primary key.

Copy file from remote server or URL

Question by Kris

I have the following code:

    $file = 'http://3.bp.blogspot.com/-AGI4aY2SFaE/Tg8yoG3ijTI/AAAAAAAAA5k/nJB-mDhc8Ds/s400/rizal001.jpg';
    $newfile = '/img/submitted/yoyo.jpg';

    if ( copy($file, $newfile) ) {
        echo "Copy success!";
    }else{
        echo "Copy failed.";
    }

and it always output “Copy failed” 

copy(/img/submitted/yoyo.jpg) [function.copy]: failed to open stream: No such file or directory

my directory is set to 777.

any ideas? thanks!

While copy() will accept a URL as the source argument, it may be having issues a url for the destination.

Have you tried specifying the full filesystem path to the output file? I’m assuming you’re not trying to put the new file onto a remote server.

For example:

$file = 'http://3.bp.blogspot.com/-AGI4aY2SFaE/Tg8yoG3ijTI/AAAAAAAAA5k/nJB-mDhc8Ds/s400/rizal001.jpg';
$newfile = $_SERVER['DOCUMENT_ROOT'] . '/img/submitted/yoyo.jpg';

if ( copy($file, $newfile) ) {
    echo "Copy success!";
}else{
    echo "Copy failed.";
}

The above worked nicely for me.

You cannot copy a file from a server without having access to it.

You can ftp_get() to open up a FTP connection and copy file.

$local_file = 'localname.zip'; // the nam
$server_file = 'servername.zip';
$conn = ftp_connect($ftp_server);

$login_result = ftp_login($conn, $ftp_user_name, $ftp_user_pass);

if (ftp_get($conn, $local_file, $server_file, FTP_BINARY)) {
    echo "Successfully copied";
}
ftp_close($conn);

If you want to download a file from URL

$fullPath = "filepath.pdf";

if ($fd = fopen ($fullPath, "r")) {
    $fsize = filesize($fullPath);
    $path_parts = pathinfo($fullPath);
    $ext = strtolower($path_parts["extension"]);
    header("Content-type: application/octet-stream");
    header("Content-Disposition: filename="".$path_parts["basename"].""");
    header("Content-length: $fsize");
    header("Cache-control: private"); //use this to open files directly
    while(!feof($fd)) {
        $buffer = fread($fd, 2048);
        echo $buffer;
    }
}
fclose ($fd);
...
