Troubleshooting file upload error code 4 - php

Question

I am trying to upload multiple files to my server. If I try to upload a single file, it works fine. but if I try more than one, it gives me an error code 4, even though it does print the name of all the files correctly. Nothing is uploaded. I have the input type set correctly. Can someone help me?
Choose Image: <input name="uploadedfile[]" type="file" multiple="true"/><br /><br /><br />
<input type="submit" value="Upload Image!" style="margin-left:100px;"/>
Below is the code:
$i=0;
foreach($_FILES['uploadedfile']['name'] as $f)
{
$file['name'] = $_FILES['uploadedfile']['name'][$i];
$file['type'] = $_FILES['uploadedfile']['type'][$i];
$file['tmp_name'] = $_FILES['uploadedfile']['tmp_name'][$i];
$file['error'] = $_FILES['uploadedfile']['error'][$i];
$file['size'] = $_FILES['uploadedfile']['size'][$i];
if ($file["error"] > 0)
{
echo "Error Code: " . $file["error"];
}
$target_path = "uploads/".basename($file["name"]);
if(move_uploaded_file($file["tmp_name"], $target_path))
{
echo basename($file['name'])."<br />";
echo basename($file['tmp_name'])."<br />";
echo $target_path;
} else{
echo "There was an error uploading the file, please try again!";
}
$i++;
}
and my HTML form
<div id="album_slider">
<div style="text-align:center;margin:20px auto;font-size:27px;">Upload Image</div>
<br style="clear:both;font-size:0;line-height:0;height:0;"/>
<div style="width:700px;margin:auto;height:250px;text-align:left;">
<form enctype="multipart/form-data" action="uploader.php" method="POST" name="form">
Image Name: <input type="text" name="image_name" id="image_name"/><br /><br /><br />
<input type="hidden" name="a_id" id="a_id" value="<?php echo $a_id; ?>"/>
Choose Image: <input name="uploadedfile[]" type="file" multiple="true"/><br /><br /><br />
<input type="submit" value="Upload Image!" style="margin-left:100px;"/>
</form>
</div>
<br style="clear:both;font-size:0;line-height:0;height:1px;"/>
</div>

Answer 1

Try:
foreach ($_FILES["uploadedfile"]["error"] as $key => $error) {
if ($error == UPLOAD_ERR_OK) {
echo "$error_codes[$error]";
move_uploaded_file(
$_FILES["uploadedfile"]["tmp_name"][$key],
$target_path
) or die("Problems with upload");
}
}

Answer 2

Well its going to fail as you want to upload MULTIPLE files, but your code is only designed to handle 1 single file.
Go ahead and read through how to handle multiple files here:

Answer 3

Use the condition check like below code
if(isset($_FILES["qImage"]) && !empty($_FILES["qImage"]["name"])){
$imgSubQuestion = $_FILES["qImage"];
}
if(isset($_FILES["sImage"]) && !empty($_FILES["sImage"]["name"])){
$imgSolution = $_FILES["sImage"];
}
