Multiple File upload with dynamic fields
<p>Can you please advise/help me with this code? I want to upload multiple files to the server and save the information in database. But this code is uploading only one file, from the first input field.</p>

<p>I have dynamic "upload file" fields, like this: </p>

<pre><code>              &lt;form action="uploader.php" method="POST" enctype="multipart/form-data"&gt;
                &lt;label&gt;Upload&lt;/label&gt;
                &lt;input type="file"  name="file[]"&gt;
                &lt;label&gt;Description&lt;/label&gt;
                &lt;input type="text" id="filedesc" name="filedesc[]"&gt;
                &lt;a href="#" onClick="addUpload('dynamicInputUpload');" &gt;
                &lt;img src="../../img/add.png" &gt;&lt;/a&gt;
        &lt;div id="dynamicInputUpload"&gt;&lt;/div&gt;
 &lt;input type="submit" float= "right"  name="add" id="add" value="UPLOAD" &gt; 
 &lt;input type="hidden" name="pid" id="pid" value="&lt;?php echo $pid; ?&gt;"&gt;
 &lt;input type="hidden" name="intnumber" id="intnumber" value="&lt;?php echo $int; ?&gt;"&gt;     
        &lt;/form&gt;    
</code></pre>

<p>Bellow is the Javascript that creates dynamic fields:</p>

<pre><code> var counterUpload = 1;
 var limit = 10;
 function addUpload(divName){
 if (counterUpload == limit)  {
      alert("You have reached the limit of adding " + counterUpload + " inputs");
 }
 else {
      var newdiv = document.createElement('div');
      newdiv.innerHTML = " &lt;label&gt;File " + (counterUpload + 1) + "&lt;/label&gt;&lt;input type=\"file\" name=\"file["+counterUpload+"]\" id=\"file["+counterUpload+"]\"&gt; &lt;label&gt;Description " + (counterUpload + 1) + "&lt;/label&gt;&lt;input type=\"text\" id=\"filedesc["+counterUpload+"]\" name=\"filedesc["+counterUpload+"]\" &gt;"
      document.getElementById(divName).appendChild(newdiv);
      counterUpload++;
 }
</code></pre>

<p>}</p>

<p>And the problem is bellow in the uploader.php. I suceed to uplaod only one (the first) file.  </p>

<pre><code>&lt;?php

$errors = $output = array();

if (!empty($_FILES['file'])){  

  // Validation loop 
  foreach($_FILES['file']['name'] as $i=&gt; $value){

  $fileName = $_FILES['file']['name'][$i];
  $fileSize = $_FILES['file']['size'][$i];
  $fileErr = $_FILES['file']['error'][$i];

  $fileExt = pathinfo($fileBase, PATHINFO_EXTENSION);
  $fileTmp = $_FILES['file']['tmp_name'][$i];

  // Construct destination path
  $fileDst = $storageDir.'/'.basename($_FILES['file']['name'][$i]);
  for ($j = 0; file_exists($fileDst); $j++) {
    $fileDst = "$storageDir/$fileName-$j.$fileExt";
  }

  // Move the file
