hi m using the phpuploader but  i want the functionlity that the user only upload the single file at a time,I   tried all the configuration to restrict the user only upload a single file. but is not working

here is code below

 

$uploader->InsertText="Upload File (Max 10M)";
   
   $uploader->MaxSizeKB=1024000; 
   $uploader->AllowedFileExtensions="jpeg,jpg,gif,png,zip";
   $uploader->MaxFilesLimit=1;
   //Where'd the files go?
   $uploader->SaveDirectory="/uploads";
   
   $uploader->Render();

 

but every time i uplod the first file it again open the file upload dialog box, i want that whenever user upload first file the upload button will be disable or it will show the alert box say "you cannot upload more the one file "

 

thankyou in advance
