Adding File Type restriction in my upload script


Adding File Type restriction in my upload script

Does that help I have an upload script that is works like a charm for uploading the files. I have also setup the upload size limit in the script. But I want to set up the file type restriction in my script but I am confused in implementing it. Can anyone help me with this? I want to allow only JPG, JPEG, PNG, GIF, PDF and DOC files. How can I do this? Please help. , Try to check the condition with the file extension
code :
$extension = substr($_FILES['photo']['name'], strrpos($_FILES['photo']['name'], '.'));

 $extension = strtolower($extension);

if( $extension == ".jpg" || $extension == ".jpeg" || $extension == ".gif" ||$extension == ".png" )
{
 // File upload code
}

this will help How I can add to these 2 scripts below a restriction, so it wont allow creating a hero with less than 3 characters in its name or when changing the name of the hero it wont allow less than 3 characters as well? , At the start of your CREATE_NEW_CHAR procedure, you could do this...
code :
IF LEN(LTRIM(@CharID)) < 3  -- LEN() does an RTRIM()
BEGIN
  SET @nRet = 7
  RETURN
END
Kendo UI Image Upload Restriction for file type isn't working

Kendo UI Image Upload Restriction for file type isn't working

wish helps you I want to restrict image upload to only jpg images using the kendo UI for ASP .NET MVC3. However, when I followed the example here,even with my manipulation below, it keeps alerting "please upload jpg image files" even when I uploaded a jpg file! In fact, it makes me select all kinds of images. How can I change it so that I can only upload jpg images and if I upload png or other type of image files, it should alert, to only upload jpg images. , You have a type-o:
code :
value.expresion == ".jpg"
value.expression == ".jpg"
if (!ok) {
   e.preventDefault();
   alert("Please upload jpg image files");
}

I think the issue was by ths following , I'm afraid it can't be done using UiApp because the file name is not available from within the doGet function. This is handled in the browser without access from apps Script.
Running a simple demo code like below will show that we just can get the widget's type and that no other method is available. The validators are useless in this case since the file name is not available.
code :
function doGet(e) {
  var app = UiApp.createApplication().setTitle('test');
  var fPanel = app.createFormPanel();
  var panel = app.createVerticalPanel();
  var text = app.createTextBox();
  var submitButton = app.createSubmitButton('<B>Submit</B>'); 
  //file upload
  var upLoad = app.createFileUpload();
  var handler = app.createClientHandler().forTargets(text).setText(upLoad);
  upLoad.setName('thefile').addChangeHandler(handler);
  app.add(fPanel.add(panel.add(upLoad).add(text).add(submitButton)));
  return app;
}

php file upload restriction for xml files via mime

php file upload restriction for xml files via mime

it helps some times It seems like $finfo->file() returns application/xml instead of text/xml for xml files.
Change your array with valid mime-types to this:
code :
array(
    'xml' => 'application/xml',
    'txt' => 'text/plain',
),
