Question

I am creating a script which allows the user to upload images but now I want to include a simple if statement which will accept only gif and png . Here is my code but it doesn’t seem to be working the way it has to .

#extention filter
$allowed = array("image/gif","image/png");  
if(!in_array($files,$allowed)){
 $error_message = 'Only jpg, gif, and pdf files are allowed.';
  $error = 'yes';
  echo $error_message;
  exit();
}   #extention

Answer 1

    $filename=$_FILE['name']['filename_in_html'];  //you can change this with your filename
    $allowed='png,jpg';  //which file types are allowed seperated by comma

    $extension_allowed=  explode(',', $allowed);
    $file_extension=  pathinfo($filename, PATHINFO_EXTENSION);
    if(array_search($file_extension, $extension_allowed))
    {
        echo "$extension_allowed allowed for uploading file";
    }
    else
    {
        echo "$extension_allowed is not allowed for uploading file";
    }
