Use a php loop to process text and file inputs from html form

Question

I am stuck on trying to make this work, I have a html form that has file and text inputs, after submission I want to process these inputs through a loop in my php script. Currently the loop skips the file input and processes only the text inputs. I am new at php, and I cant seem to understand what is wrong and how to fix it. Here is the form code and the php code to process it.

<form action='loop.php' enctype="multipart/form-data" data-ajax="false" method="POST">
     <input type ="text" name ="Input1"/>
     <input type ="file" name ="Input2"/>
     <input type ="text" name ="Input3"/>
     <input type ="text" name ="Input4"/>
     <input type='submit' data-corners="false" value ='submit'/>
</form>

loop.php

<?php
    foreach ($_POST as $key => $value){
         if($_POST[Input2]) //check if its the file input
         {//some manipulation on the file}
         else
         //process all other text inputs}
?>

Thanks for your help

$_POST[Input2] is wrong, but it should work. That's because Input2 is recognized as constant, not as string (what it should be). Change that into $_POST['Input2'] (see also PHP manual).
You haven't closed some of the brackets. Pay attention to the legibility of your code to avoid this!
$_POST[Input2] doesn't check if the currently processed input is Input2. You should do this with $key.

Currently the loop skips the file input and processes only the text inputs. This is an issue with $_FILES[], not an issue with his input constants. Good effort, though.
