Rename on upload

[JayLewis]

This is the function i use to upload images to my server in a certain directory...

how would i change the file name on upload?

 

thanks.

 

<? 
$dir=opendir("image/upload"); 

$i=0; 
while($imgfile=readdir($dir)) 
{ 
     if ($imgfile != "." && $imgfile!="..") 
         { 
        $imgarray[$i]=$imgfile; 
        $i++; 
        } 
} 

closedir($dir); 

$rand=rand(0,count($imgarray)-1); 

    if($rand >= 0) 
    { 
    echo '<img src="image/upload/'.$imgarray[$rand].'" width="125" height="125">'; 
//replace path, width & height sizes to fit your needs 
    } 
?>

I don't see any uploading happening...  looks like that just displays a random image from the "image/upload" directory.

My Bad i got the wrong bit of code.. sorry

 

<?php 
$target = "image/upload/"; 
$target = $target . basename( $_FILES['uploaded']['name']) ; 
$ok=1; 
if(move_uploaded_file($_FILES['uploaded']['tmp_name'], $target)) 
{
echo "The file ". basename( $_FILES['uploadedfile']['name']). " has been uploaded";
} 
else {
echo "Sorry, there was a problem uploading your file.";
}

?>

<?php 
$target = "image/upload/"; 
$target = $target . "newnameappend-". basename( $_FILES['uploaded']['name']) ; // This is where you designate a new name.
$ok=1; 
if(move_uploaded_file($_FILES['uploaded']['tmp_name'], $target)) 
{
echo "The file ". basename( $_FILES['uploadedfile']['name']). " has been uploaded";
} 
else {
echo "Sorry, there was a problem uploading your file.";
}

?>

ahh there ya go

 

So here when you're using move_uploaded_file() that's where you're actually renaming the temporary file to (in your case) the filename in $target.  You do not by any means have to use the name from $_FILES['uploaded']['name'].

Explains it perfectly.

 

And you are right by no means are u required to use the name stored in $_FILES.

Ahhh,

 

Thanks alot people much appreciated. Works a treat

 

Nice one!

[JayLewis]

would it be possible to change the name alltogether?

 

newnameappend-picname.jpg is what i am getting...

 

is there a way to make it like:

 

newnameappend-001

[per1os]

<?php 
$target = "image/upload/"; 
$target = $target . "newnameappend-001.jpg" ; // This is where you designate a new name. That and .jpg should match the uploaded extension.
$ok=1; 
if(move_uploaded_file($_FILES['uploaded']['tmp_name'], $target)) 
{
echo "The file ". basename( $_FILES['uploadedfile']['name']). " has been uploaded";
} 
else {
echo "Sorry, there was a problem uploading your file.";
}

?>

So i upload a pic its named:

 

newnameappend-001

 

you upload one its called:

 

newnameappend-002

 

right?

You would need some way to increment to the next one, either a text file that stores the last value and you read it than increment it one than write it again or database or something.

<?php
$incrementVal = $oldVal++; // add one to old val note old val is not set in this script, you need to decide that.
$target = "image/upload/";
$target = $target . "newnameappend-".$incrementVal.".jpg" ; // This is where you designate a new name. That and .jpg should match the uploaded extension.
$ok=1;
if(move_uploaded_file($_FILES['uploaded']['tmp_name'], $target))
{
echo "The file ". basename( $_FILES['uploadedfile']['name']). " has been uploaded";
}
else {
echo "Sorry, there was a problem uploading your file.";
}

?>

My php skills are very basic...

 

how would i go about setting the "old Val"?

[per1os]

One way is using the fopen, fread, fwrite and fclose

 

http://us3.php.net/manual/en/function.fopen.php

 

<?php
$oldVal = file_get_contents('nextval.txt');
$fp = fopen('nextval.txt', 'w');
fwrite($fp, ($oldval + 1));
fclose($fp);

?>
