File Size, Image Size

Hi,

maybe I asked that times before, but its hard to figure out how that works and how it should be inserted into the page.

Again, it starts with all those enteries in the bindings panel. UPLOAD-FILE and FORM[0] where you can find th informations for the upload file.


I want to limit the filesize to 1MB - and have an error message (filesize is to big)

I want to limit the min image size to 50px width - and an error message (your file needs to be bigger that 50px width)

I want it required to upload an image - error message (please choose an image file)

I want only images - Errormessage (only images are allowed)


does that only work with server validation? How does it work? Which validation type do I choose?

It would be nice to have a tutorial for that, so that I dont have to ask again and again. DFP was easier cause it checks the file size etc.

Thanks for hlep and patience

OK, I got now...

file size
image size
and requiring

but how do I check the extension?

If I use servervalidation file extension, server variable form[0] image extension

but that does not work. I want to have all checked with server validation :-)

Use the File Extension server validation, For server variable, click the ligtning bolt and select the file Field Simple File Name bindings from the form binding collection.

for the valid file extension list, do not include the dots. for example to allow gif and jpg, the extension list will look like:
gif jpg jpeg

change:

php:
$WAFV_Errors .= WAValidateFE(((isset($_FILES["image"]))? preg_replace('/.[^.]*$/', '', $_FILES["image"]["name"]) :"") . "","gif jpg jpeg png",true,2);



to;

php:
$WAFV_Errors .= WAValidateFE(((isset($_FILES["image"]))? preg_replace('/^[^\.]*/', '', $_FILES["image"]["name"]) :"") . "",".gif .jpg .jpeg .png",true,2);

My apologies, I was steering you wrong.

the server variable to use is the Client file name.

and the extension list should contain the dots and be comma separated:
.gif, .jpg, .jpeg, .png


php:
$WAFV_Errors .= WAValidateFE(((isset($_FILES["image"]))? preg_replace('/.[^.]*$/', '', $_FILES["image"]["name"]) :"") . "","gif jpg jpeg png",true,2);



should be changed to:

php:
$WAFV_Errors .= WAValidateFE(((isset($_FILES["image"]))?  $_FILES["image"]["name"] :"") . "",".gif, .jpg, .jpeg, .png",true,2);





sorry for leading you astray.

ok, it seems to work :-) thank you.

but I was a little confused about ClientFileName, cause this is only to find "upload files". If I take the simple FielField it works.

So, always I want to check something in the upload I take the ImageAttributes in my FORM?

What are the UPLOAD FILES attributes for? There are also 2 diffrent attributes (see server files2.jpg).

Thanks for your help!

One last question :-)

How do I get the size to limit the file-size. for example 1MB, the number must be 1000000 or something.

Same, when I check width and/or height, what do I enter, if I want to check the limit of 50px?

Cheers
Denis

Everything seems to work, exept the Image-Width and Height check :-(

$height = -1;

if(isset($fileField) && isset($fileField["tmp_name"]) && isset($fileField["type"]) && isset($WA_ImageContentTypes[$fileField["type"]]) ){
$dimensions = getimagesize($fileField["tmp_name"]);
$height = $dimensions[1];
}
return $height;
}
}
?>
<?php
