Traversing through $_FILES array

[Markus]

Ok, so i'm doing the multiple file upload thingymabob!

I'm just playing around really...

When i try to check the file type i simply get Array().

[php]
foreach ($_FILES['file']['name'] as $_key => $_value)
{
echo $_value . " was uploaded successfully.<b r />";
echo $_FILES['file']['type'] . " <br />";
}
[/php]

So to traverse through the array i added a foreach:

[php]
foreach ($_FILES['file']['name'] as $_key => $_value)
{
echo $_value . " was uploaded successfully.<b r />";
foreach($_FILES['file']['type'] as $_x => $_y){
echo $_value . " is in $_y format<br />";
}
}
[/php]
But that gives me this:

ut_the_folk_down1.gif was uploaded successfully.
put_the_folk_down1.gif is in image/gif format
put_the_folk_down1.gif is in image/jpeg format
natnme.jpg was uploaded successfully.
natnme.jpg is in image/gif format
natnme.jpg is in image/jpeg format

When i just want:

ut_the_folk_down1.gif was uploaded successfully.
put_the_folk_down1.gif is in image/gif format
natnme.jpg was uploaded successfully.
natnme.jpg is in image/jpeg format

I'm stumped ...

Hi,

I think it's because you loop though the whole array, if you index the array using the filename, $_value, you should only get the filetype for that one.

Now you're getting the whole content.

Hope this helps.

Yup. MarkoKlacar is correct. I think you should write something like this instead:

[PHP]
foreach ($_FILES as $_key => $_value)
{
echo $_FILES[$_key]['name'] . " was uploaded successfully.<b r />";
echo $_FILES[$_key]['name'] . " is in " . $_FILES[$_key]['type'] . " format<br />";
}
[/PHP]
I'm not quite sure if it will work since I can't test it on this computer. But try it out ;) The syntax might be wrong, but I guess the structure is correct.

Thanks guys!

After stirring the logic soup in my brain a little, you guided me into this:

[php]
foreach ($_FILES['file']['name'] as $_key => $_value)
{
echo $_value . " was uploaded successfully.<b r />";
echo $_FILES['file']['type'][$_key]."<br />";
}
[/php]

I originally tried to put the key before the ['type'] thinking that the key would have to come immediately after the file array, but i was wrong :P

Thanks again!
