Question

I have made this script for uploading remote files but the file is not uploaded to server and the database for var1 remains empty. Here is my code.

HTML:

<form enctype="multipart/form-data" id="form1" method="post" action="">
    <p><label>Upload songs</label>      
    <input type="text" name="song"><input type="submit" value="Submit" class="button"></p>
</form>

PHP:

$uri = copy1_file($_POST['song']);
$story['v1'] = $uri;

        $url = $_POST['song'];
    $file = fopen ($url, "rb");
    if ($file) {
        $newf = fopen ($uri, "wb");
        if ($newf) {
            while(!feof($file)) {
                fwrite($newf, fread($file, 1024 * 8 ), 1024 * 8 );
            }
        }
    }
    if ($file) {
        fclose($file);
    }
    if ($newf) {
        fclose($newf);
    }
    else {
        return false;
    }
}

I have checked the error log but nothing is coming. Where I am doing a mistake?

Answer 1

Read up on PHP File Uploads .

Try this to debug your script:

var_dump($_FILES);

Do you see anything?

EDIT: Okay, I see you more clearly defined "remote files." You have to use a "text" input to receive the URL. How did you get around the standard file selection dialog?

It looks like your code will work as-is if you just change the <input/> type to "text".

EDIT 2: I noticed you updated your post to have <input type="text"/> so you already have a URL making it through to your script. Check to see if your host has allow_url_fopen enabled. If not, your URL will not be retrieved by fopen() . You will have to use cURL instead.

EDIT 3: Could it be that your copy1_file function never actually returns the uri? There are a lot of errors in the code in that function. Ex: copy1_file is receiving a url, why does it have $file['name'] at the top? And later reference $_POST directly? There are more errors. Check it closely and correct them, then it should work fine since you say fopen(url) is known to work with your host.

Answer 2

you need to use $_FILES array to access uploaded files instead of $_POST

here is the sample code for handling file uploads:

$pathToSaveFile = '...'; // this is the file path where the uploaded file should be saved
move_uploaded_file($_FILES['song']['tmp_name'], $pathToSaveFile);

UPDATE

if you need just to upload a file by URL then you don't need <input type="file"> , just use simple <input type="text"> and after user inserts URL and submits, you can use file_get_contents and file_put_contents functions:

file_put_contents($pathToSavePath, file_get_contents($_POST['song']));

to be able to use these functions to download remote files, make sure that allow_url_fopen option of PHP is set to TRUE
