$_FILES["variable goes here"]

[JAG90]

Is it possible to put a variable in the brackets. I am trying to loop through some files and need a variable here

                      \/

 

$_FILES["some variable in here"]

 

anyone know how to do this?

Yes its possible. Post your problematic code.

Ok ... so here is a snippet hopefully you can see wot i am doin from this. in the $arr variable there are files that have been sent to the server through a file <input>

foreach($arr as $var){
unset($imagename);

if(!isset($_FILES) && isset($HTTP_POST_FILES))
$_FILES = $HTTP_POST_FILES;

if(!isset($_FILES["$var"]))
$error["$var"] = "An image was not found.";

$filename = basename($_FILES["$var"]['name']);
$maxsize = 2621440;
if(filesize($filename) > $maxsize)
$error["$var"] = "The image is too large, the image must be ". $maxsize ." bytes or smaller" ;
echo $error["$var"];

We don't understand your coding. Are you new to PHP? It seems like you never close your if statements... or even open them.

I am kinda new to php but the code I submitted is just a small snippet to show what i am trying to do with the code. Just imagine it as a completely working page. everything is working i just need to get a variable into the $_FILES["  ]

 

I need to get the $var into the $_FILES["    "] so that the checking of the files and the making of thumbnails work.

Why not just foreach the files. If $_FILES is a multi-dimensional array this would be better.

 

<?php
foreach ($_FILES as $key => $val) {
    if (is_array($val)) {
          echo "File at $key is named " . $_FILES[$key]['name'] . "<br />"; 
    }
}
?>

 

I am not keen on file uploads, but see what that gives you. If it works, then just modify items inside the if statement to do what you want. If not maybe look for a multiple file upload php tutorial and see how it is really done.

ok ... i dont understand how that would help me ... this is the code i am working with:

Your form fields should be an array (note I explicitly entered index numbers to match what you are currently doing instead of allowing the index to automatically start at zero, which what most code examples will be showing)  -

 

   <input type="file" name="image_file[1]" size="20"/><br />
   <input type="file" name="image_file[2]" size="20"/><br />
   <input type="file" name="image_file[3]" size="20"/><br />
   <input type="file" name="image_file[4]" size="20"/><br />
   <input type="file" name="image_file[5]" size="20"/>

 

This will result in an array - $_FILES['image_file'] that you can simply iterate over in a loop instead repeating code to handle each file. There's actually a section in the php manual that shows this and it also shows the resulting $_FILES variables - http://www.php.net/manual/en/features.file-upload.multiple.php
