Failed to upload a file in PHP - php

Question

I try to upload an image, but it is not working. Other variables I have set are inserted into database, but image file is not... I was trying to check submit with isset, but it is not working. Where is my error?
Thanks for your help.
PHP file:
<?php
include ('includes/config.php');
$mysqli = new mysqli(DB_SERVER,DB_UNAME,DB_PASSWD,DB_NAME);
if($mysqli->connect_errno) {
echo "MYSQLI connect error no {$mysqli->connect_errno} : {$mysqli->connect_error}";
die();
}
$itemcode = $_POST['icode'];
$itemname = $_POST['iname'];
$brandname = $_POST['brandname'];
$upload = basename ($_FILES['upload']['name']);
$path = "img/";
if(!empty($upload)) {
$i1 = strrpos($upload,".");
if (!$i1) {
return "";
}
$l1 = strlen($upload) - $i1;
$ext1 = substr($upload,$i1+1,$l1);
$ext1 = strtolower($ext1);
$news_name1=time()+(1).'.'.$ext1;
$newname1 = $path.$news_name1;
$copied1 = copy($_FILES['upload']['tmp_name'], $newname1);
} else {
$news_name1 = '';
}
$iadd = $mysqli->prepare("INSERT INTO table_item (`itemcode`,`itemname`,`brandname`,`upload`) VALUES ('".$itemcode."', '".$itemname."','".$brandname."','".$news_name1."') ");
$iadd->execute();
$iadd->close();
$mysqli->close();
?>
This is my HTML file:
<form class="cmxform form-horizontal tasi-form" name="form2" id="form2" method="post" action="">
<div class="form-group ">
<label for="icode" class="control-label col-lg-2">Item Code</label>
<div class="col-lg-10">
<input class=" form-control" id="icode" name="icode" type="text" />
</div>
</div>
<div class="form-group ">
<label for="iname" class="control-label col-lg-2">Item Name</label>
<div class="col-lg-10">
<input class=" form-control" id="iname" name="iname" type="text" />
</div>
</div>
<div class="form-group ">
<label for="brandname" class="control-label col-lg-2">Brand Name</label>
<div class="col-lg-10">
<input class=" form-control" id="brandname" name="brandname" type="text" />
</div>
</div>
<fieldset style="width:48%; float:left;"> <!-- to make two field float next to one another, adjust values accordingly -->
<label>Doc 2</label>
<input style="margin: 0 10px;" type="file" name="upload" size="50">
</fieldset>

Answer 1

Add 'enctype="multipart/form-data"' to your form tag attributes, you can read more about file uploading here.
Also consider checking the values of the post, because your current method can get you sql injections

Answer 2

add form attribute enctype="multipart/form-data"

Answer 3

You have not proper syntax used and also use 'enctype="multipart/form-data"'.
I have implemented your code
<?php
include ('includes/config.php');
$mysqli = new mysqli(DB_SERVER,DB_UNAME,DB_PASSWD,DB_NAME);
if($mysqli->connect_errno){
echo "MYSQLI connect error no {$mysqli->connect_errno} : {$mysqli->connect_error}";
die();
}
$itemcode = $_POST['icode'];
$itemname = $_POST['iname'];
$brandname = $_POST['brandname'];
$upload = basename ($_FILES['upload']['name']);
$path = "img/";
if(!empty($upload)){
$i1 = strrpos($upload,".");
if (!$i1) { return ""; }
$l1 = strlen($upload) - $i1;
$ext1 = substr($upload,$i1+1,$l1);
$ext1 = strtolower($ext1);
$news_name1=time()+(1).'.'.$ext1;
$newname1 = $path.$news_name1;
$copied1 = $_FILES['upload']['tmp_name'], $newname1;
}else{
$news_name1 = '';
}
$iadd = $mysqli->prepare("INSERT INTO table_item (`itemcode`,`itemname`,`brandname`,`upload`) VALUES ('".$itemcode."', '".$itemname."','".$brandname."','".$news_name1."') ");
$iadd->execute();
$iadd->close();
$mysqli->close();
?>
