extracting the extension

[jmr3460]

I have got this code that I did that gets the extension from an uploaded file. I used

$_FILES['uploadedfile'] ['type'] and exploded the string to get my extension. My question: Is there a more reliable way to do this? This is my code:

	if (!empty($_FILES['uploadedfile']['tmp_name']))
{
	$file = $_FILES['uploadedfile']['tmp_name'];
	$old_file = basename($_FILES['uploadedfile']['tmp_name']);

	//Trying to get ext here
	$find_ext = explode('.', $old_file);
	//$ext = $find_ext[1];//line 16
	$find_type = $_FILES['uploadedfile']['type'];
	$get_ext = explode('/', $find_type);
	$ext = $get_ext[1];

	//This connects to server and select database
	//This section get information from db table for rename
	//START GET RENAME
	$db_name = "crowleys_minutes";
	$connection = mysql_connect("localhost", "user", "pw")or trigger_error(mysql_error());
    $db = mysql_select_db($db_name, $connection) or die(mysql_error());
    $sql = "SELECT * FROM minutes WHERE inserted = 0 LIMIT 1";
    $query = mysql_query($sql) or trigger_error(mysql_error());
    $result = mysql_fetch_array($query);
    $minute_id = $result['minute_id'];
    $id = sprintf('%03d',$minute_id);
    $year_folder = $result['year'];
    $area_date = $result['area_date'];
    $newfilename =  $id . "-crascmin" . $area_date . "." .$ext;//need to add $ext here
    $target_folder = "/home/crowleys/public_html/minutes/docs/" . $year_folder . "/";
    $target = $target_folder . $newfilename;
    //END GET RENAME
    //Here is where I am having trouble
	$upload = move_uploaded_file($file, $target);
		if ($upload){
			echo "Wa Hoo";
    }
    else
    {
        echo "There was an error uploading the file, please try again!";
    }
  }

I still have a little clean up to do. I think there are some unused variables that need to be removed.

Thanks for any help or suggestions.

pathinfo()

 

<?php
$ext = pathinfo ($_FILES['uploadedfile']['name']);
$ext = $ext['extension'];
?>

[salathe]

Or, to save a temporary variable, pathinfo($_FILES['uploadedfile']['name'], PATHINFO_EXTENSION)

 

See http://php.net/pathinfo for details.

This only brings the p from the pdf.

	$get_ext = pathinfo($_FILES['uploadedfile']['name'], PATHINFO_EXTENSION);
	$ext = $get_ext['extension'];

You don't need that second line.

Thanks for the help. That did it.

I guess there is not a problem solved anymore?

The modification, I believe, has yet to be re-added since the forum software upgrade. In the mean time, folks will just have to be old school and take a look at the posts to see if a thread has been solved.
