Storing a video in a database then retrieving it - php

Can someone please tell me what I have done wrong with this code, I am connecting to localhost to the database called video. Then I am inserting in to table location and its column location the value $videoLocation.
The result I get is when I open my browser is
<?php
echo "Upload: " . $_FILES["file"]["name"] . "<br />";
echo "Type: " . $_FILES["file"]["type"] . "<br />";
echo "Size: " . ($_FILES["file"]["size"] / 1024) . " Kb<br />";
echo "Temp file: " . $_FILES["file"]["tmp_name"] . "<br />";
?>
What I am trying to achieve with this code is for the video to appear on my webpage once a user has submitted it.
<?php
$allowedExts = array("jpg", "jpeg", "gif", "png", "mp3", "mp4", "wma");
$allowType = array("video/mp4","audio/mp3","audio/wma","image/png","image/gif","image/jpeg");
$maxSize = 20000000000000;
$extension = pathinfo($_FILES['file']['name'], PATHINFO_EXTENSION);
$pathToUpload = 'upload/';
if( in_array($_FILES["file"]["type"], $allowType) && in_array($extension, $allowedExts) && $_FILES["file"]["size"] <= $maxSize)
{
if ($_FILES["file"]["error"] > 0)
{
echo "Return Code: " . $_FILES["file"]["error"] . "<br />";
}
else
{
echo "Upload: " . $_FILES["file"]["name"] . "<br />";
echo "Type: " . $_FILES["file"]["type"] . "<br />";
echo "Size: " . ($_FILES["file"]["size"] / 1024) . " Kb<br />";
echo "Temp file: " . $_FILES["file"]["tmp_name"] . "<br />";
if (file_exists($pathToUpload . $_FILES["file"]["name"]))
{
echo $_FILES["file"]["name"] . " already exists. ";
}
else
{
move_uploaded_file($_FILES["file"]["tmp_name"], $pathToUpload . $_FILES["file"] ["name"]);
$videoLocation = "upload/".$_FILES['file']['name'];
// now insert $videoLocation into a database table
$db = new mysqli('127.0.0.1', 'root', '', 'video');
INSERT INTO location (location)
VALUES ($videoLocation)
//so you can fetch it on whatever page you feel like
}
}
}
else
{
echo "Invalid file";
}
?>

try this
$db = new mysqli('127.0.0.1', 'root', '', 'video');
$stmt = $db->prepare("INSERT INTO location (location) VALUES (?)");
$stmt->bind_param('s', $videoLocation);
$stmt->execute();
//so you can fetch it on whatever page you feel like

I recently answer a question for someone else who wanted to store image files in the database. Here is how to do it:
1) the database column must be defined as longblob.
Next, the code uses PDO rather than mysqli.
// database connection...
$dsn = 'mysql:host=localhost;dbname=testmysql';
$username = 'test';
$password = 'test';
$options = array(
PDO::MYSQL_ATTR_INIT_COMMAND => 'SET NAMES utf8',
);
$connection = new PDO($dsn, $username, $password, $options);
$connection->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
Then you need an open file handle as follows:
$fileVideo = fopen($videoLocation,'rb');
Then you prepare your statement and bind the file:
$stmt = $connection->prepare("INSERT INTO location (location) VALUES (?)");
$stmt->bindParam(1, $fileVideo, PDO::PARAM_LOB);
$connection->beginTransaction();
$stmt->execute();
$connection->commit();
fclose($fileVideo);
I haven't test the above on your files but the original code that was like the above but with names changes worked fine.

Php how to display the video?

I have a code and I would like to edit it so that the video uploaded shows up on my webpage and is then stored in the upload folder.
Code:
<?php
$allowedExts = array("jpg", "jpeg", "gif", "png", "mp3", "mp4", "wma");
$allowType = array("video/mp4","audio/mp3","audio/wma","image/png","image/gif","image/jpeg");
$maxSize = 20000000000000;
$extension = pathinfo($_FILES['file']['name'], PATHINFO_EXTENSION);
$pathToUpload = 'upload/';
if( in_array($_FILES["file"]["type"], $allowType) && in_array($extension, $allowedExts) && $_FILES["file"]["size"] <= $maxSize)
{
if ($_FILES["file"]["error"] > 0)
{
echo "Return Code: " . $_FILES["file"]["error"] . "<br />";
}
else
{
echo "Upload: " . $_FILES["file"]["name"] . "<br />";
echo "Type: " . $_FILES["file"]["type"] . "<br />";
echo "Size: " . ($_FILES["file"]["size"] / 1024) . " Kb<br />";
echo "Temp file: " . $_FILES["file"]["tmp_name"] . "<br />";
if (file_exists($pathToUpload . $_FILES["file"]["name"]))
{
echo $_FILES["file"]["name"] . " already exists. ";
}
else
{
move_uploaded_file($_FILES["file"]["tmp_name"], $pathToUpload . $_FILES["file"]["name"]);
echo "Stored in: " . "upload/" . $_FILES["file"]["name"];
}
}
}
else
{
echo "Invalid file";
}
I am not looking for someone to give me the code but to point me in the right direction.
At the point where the video is moved and you are echo'ing its location:
"Stored in: " . "upload/" . $_FILES["file"]["name"];
instead of echo'ing where it's stored you could add it to a videos table of some sort:
$videoLocation = "upload/".$_FILES['file']['name'];
// now insert $videoLocation into a database table
//so you can fetch it on whatever page you feel like

if then statement equivalent in php

I am newish to php. But when i learned to program it was on a TI-83 Calculator. with the TI83 their was an if-then statements the could be used. I am writing some code to check if a directory is already created and if not create it. I need it to run the last half of the code either way. here is the code.
<?php
$dir = "/Applications/XAMPP/xamppfiles/htdocs/upload/$_POST[Itemid]/" ;
if (!file_exists($dir) and !is_dir($dir)) {
$upload_dir = mkdir($dir, 0777);
}else{
foreach ($_FILES["file"]["error"] as $key => $error) {
if ($error == UPLOAD_ERR_OK) {
$filename = $_FILES["file"]["name"][$key];
$filetemp = $_FILES["file"]["tmp_name"][$key];
$filetype = $_FILES["file"]["type"][$key];
$filesize = $_FILES["file"]["size"][$key];
if (file_exists($dir . $filename))
{
echo $filename . " already exists. <br><br>";
}
else
{
echo "Upload: " . $filename . "<br>";
echo "Type: " . $filetype . "<br>";
echo "Size: " . ($filesize / 1024) . " kB<br>";
echo "Temporarily Stored in: " . $filetemp . "<br>";
move_uploaded_file($filetemp,"$dir/$filename");
echo "uploaded the file \"" . $filename. "\" to the \"/Applications/XAMPP/xamppfiles/htdocs/upload/\" Directory<br>" ;
$con=mysqli_connect("localhost","root","","Inventory");
// Check connection
if (mysqli_connect_errno())
{
echo "Failed to connect to MySQL: " . mysqli_connect_error();
}
$sql="INSERT INTO ListPics (`1`, `Item_ItemID`)
VALUES
('$dir$filename', '$_POST[Itemid]')";
if (!mysqli_query($con,$sql))
{
die('Error: ' . mysqli_error($con));
}
echo ($filename. " added to Database<br><br>");
mysqli_close($con);
}
}
}
}
?>
Yes I know this code is not secure. It will not ever see the interweb(Reverently bows head and says "Thank you Al Gore") It will sit snugly behind a VPN for personal use only. I just need to know how to execute the PHP equivalent of If Then Statements
This is simple:
if(condition) {
/* do something if condition is true */
}
else {
/* do something else if condition is false */
}
/* do other stuff either way */
You only need the else if there is something that you want to do only if the condition is false. If you want to do it either way, then don't use else at all.

PHP script processing all lines of a file twice

I have a PHP script that generates an HTML form for users to upload a file. I save that file on the server using move_uploaded_file then read it using fgets() and perform database inserts based on certain check. Here's a simplified version of the code:
$cart_id = 18566;
if (empty($_POST))
{
echo "<form name=\"upload\" action=\"myscan.php\" id=\"myScan\" method=\"POST\" enctype=\"multipart/form-data\">";
echo "Choose the file to upload:<br>\r\n";
echo "<input type=\"hidden\" name=\"MAX_FILE_SIZE\" value=\"300000\" form=\"myScan\" />";
echo "<input type=\"file\" name=\"file\" form=\"myScan\" id=\"fileUp\" /><br>";
echo "<input type=\"submit\" value=\"Upload\" name=\"sub\" form=\"myScan\" />";
echo "<input type=\"hidden\" name=\"ck\" form=\"myScan\" value=\"".$cart_id."\" />";
echo "</form><br>";
}
else
{
// link to cart goes here
}
$fname = "1SCAN20131031123456";
if (!empty($_POST))
{
$allowedExts = array("txt", "csv");
$extension = end(explode(".", $_FILES["file"]["name"]));
if ( ($_FILES["file"]["type"] == "text/plain"
|| $_FILES["file"]["type"] == "application/vnd.ms-excel")
&& array_search(strtolower($extension), array_map('strtolower', $allowedExts)) !== FALSE )
{
if ($_FILES["file"]["error"] > 0)
{
echo "Error: " . $_FILES["file"]["error"] . "<br>";
}
else
{
echo "Upload: " . $_FILES["file"]["name"] . "<br>";
echo "Type: " . $_FILES["file"]["type"] . "<br>";
echo "Size: " . ($_FILES["file"]["size"] / 1024) . " kB<br>";
echo "Stored in: " . $_FILES["file"]["tmp_name"]."<br>";
if (file_exists("upload/" . $_FILES["file"]["name"]))
{
echo $_FILES["file"]["name"] . " already exists. ";
}
else
{
move_uploaded_file($_FILES["file"]["tmp_name"], $fname);
echo "Moved to: " . $fname . "<br>";
}
}
}
else
{
echo "Invalid file<br>";
echo "Type: " . $_FILES["file"]["type"] . "<br>";
echo "Upload: " . $_FILES["file"]["name"] . "<br>";
echo "Extension: " . $extension . "<br>\n";
}
At this point the file $fname is ok, no duplicated lines. The next part is called as a function declared in the same PHP file. $link, $fname, and $cart_id are declared as globals
$bn = basename($fname);
$sfd = fopen($fname, "r");
$store_number = "$bn[0]";
if(is_numeric($bn[1]))
$store_number .= $bn[1];
$a = stripos($bn, "SCAN");
$a += 4;
$dt = substr($bn, $a);
// echo "Date = $dt \n";
$fy = substr($dt, 0, 4);
$fM = substr($dt, 4, 2);
$fd = substr($dt, 6, 2);
$fh = substr($dt, 8, 2);
$fm = substr($dt, 10, 2);
$fs = substr($dt, 12, 2);
$fdate = "$fy-$fM-$fd $fh:$fm:$fs";
// echo $fname . ",";
// echo $store_number . ",";
while ($line = fgets($sfd))
{
$li = explode(",", $line);
if (sizeof($li) == 5)
{
$scan = $li[0];
$poQty = $li[1];
$cntQty = $li[2];
$limd = $li[3];
$lihms = $li[4];
$query = "INSERT INTO upload_datalog (file_name, store, filedate, scan, po_qty, cnt_qty, scan_md, scan_hms, cart_id)\n"
. "VALUES (\"$bn\", $store_number, \"$fdate\", \"$scan\", $poQty, $cntQty, \"$limd\", \"$lihms\", $cart_id)";
mysqli_query($link, $query);
}
else if ($fM < 8 || ($fM == 8 && $fd < 16 ))
{
$scan = $li[0];
$poQty = $li[2];
$cntQty = $li[1];
$limd = $li[3];
$lihms = $li[4];
$query = "INSERT INTO upload_datalog (file_name, store, filedate, scan, po_qty, cnt_qty, scan_md, scan_hms, cart_id)\n"
. "VALUES (\"$bn\", $store_number, \"$fdate\", \"$scan\", $poQty, $cntQty, \"$limd\", \"$lihms\", $cart_id)";
mysqli_query($link, $query);
}
else if (sizeof($li) == 3 && $li[0] != "" && $li[1] != "" &&$li[2] != "" )
{
$scan = $li[0];
$poQty = $li[2];
$cntQty = $li[1];
$query = "INSERT INTO upload_datalog (file_name, store, filedate, scan, po_qty, cnt_qty)\n"
. "VALUES (\"$bn\", $store_number, \"$fdate\", \"$scan\", $poQty, $cntQty)";
mysqli_query($link, $query);
}
}
fclose($sfd);
The file contains this information:
This all works more than 99 percent of the time, but twice in the past 2 weeks, the entries in the upload_datalog table have been duplicated. There is another function after this that also reads the file and performs inserts based on different checks, and those are duplicated as well.
I know this is an edge case, but I couldn't find any information as to why this would happen on php.net or through google, and I have not been able to reproduce it mysqlf. But I know it occurs in the wild.
Is there a race condition I'm not seeing here?
You do your inserts in a while loop, so you run twice through that loop?
For debugging, add a counter in your loop and create a small debug function, and a debug table. Insert the counter and data in your debug table. Compare these values with your expectations

PHP iFrame Upload Confirmation

So i have a file upload feature on my site and rather than redirect to the php script page, I want to have an iframe that displays the message returned by the script. So here's my html:
<iframe class="iframe" name="my_iframe" src="upload_file.php" style="display:none;"></iframe>
<form id="uploadForm" action="upload_file.php" method="post" enctype="multipart/form-data" target="my_iframe">
So basically I want to hide my iframe UNTIL I the upload process finishes and the script returns a message. Here's my php script:
<?php
ini_set('display_errors', 'On');
error_reporting(E_ALL | E_STRICT);
session_start();
$allowedExts = array("doc", "docx");
$extension = pathinfo( $_FILES["upload"]["name"],PATHINFO_EXTENSION);
$username = $_SESSION["username"];
if (($_FILES["upload"]["size"] < 200000)
&& in_array($extension, $allowedExts)) {
if ($_FILES["upload"]["error"] > 0)
{
echo "Return Code: " . $_FILES["upload"]["error"] . "<br />";
}
else
{
echo "Upload: " . $_FILES["upload"]["name"] . "<br />";
echo "Type: " . $_FILES["upload"]["type"] . "<br />";
echo "Size: " . ($_FILES["upload"]["size"] / 1024) . " Kb<br />";
echo "Temp file: " . $_FILES["upload"]["tmp_name"] . "<br />";
$dir_exists = is_dir("/disks/*/*/*/*/". $_SESSION["FirstName"] ."-".$_SESSION["username"]."/");
$file_exists = file_exists("/disks/*/*/*/*/".$_SESSION["FirstName"] ."-".$_SESSION["username"]."/" . $_FILES["upload"]["name"]);
$folderName=$_SESSION["FirstName"];
$baseDir = "/disks/*/*/*/*/";
// Create directory if it does not exist
if (! $dir_exists) {
if (is_writable($baseDir)) {
mkdir($baseDir . $_SESSION["FirstName"]."-".$_SESSION["username"]);
} else {
trigger_error($baseDir. " is not writeable");
}
}
if ($file_exists) {
echo $_FILES["upload"]["name"] . " already exists. ";
} else {
$link = new PDO('mysql:host=***;dbname=***;charset=UTF-8','***','***');
$proptype = $_POST["prop_cat"];
$stmt = $link->prepare("UPDATE Table SET `PType`=:proptype WHERE Username=:username");
$stmt->bindParam(':username', $username);
$stmt->bindParam(':proptype', $proptype);
$stmt->execute();
move_uploaded_file($_FILES["upload"]["tmp_name"],
$baseDir. $_SESSION["FirstName"] ."-".$_SESSION["username"]."/". $_FILES["upload"]["name"]);
echo "Stored in: " . $baseDir. $_SESSION["FirstName"] ."-".$_SESSION["username"]."/". $_FILES["upload"]["name"];
}
}
} else {
echo "Invalid file";
}
?>
So basically to sum up my question: How can I hide the iframe until upload finishes, and then display it with the message that the user can close like an alert box?
Can you echo the Iframe at the end of the upload instead of trying to hide it then show it at the top?
if ($file_exists) {
echo $_FILES["upload"]["name"] . " already exists. ";
} else {
$link = new PDO('mysql:host=***;dbname=***;charset=UTF-8','***','***');
$proptype = $_POST["prop_cat"];
$stmt = $link->prepare("UPDATE Table SET `PType`=:proptype WHERE Username=:username");
$stmt->bindParam(':username', $username);
$stmt->bindParam(':proptype', $proptype);
$stmt->execute();
move_uploaded_file($_FILES["upload"]["tmp_name"],
$baseDir. $_SESSION["FirstName"] ."-".$_SESSION["username"]."/". $_FILES["upload"]["name"]);
echo "Stored in: " . $baseDir. $_SESSION["FirstName"] ."-".$_SESSION["username"]."/". $_FILES["upload"]["name"];
/// load the iframe now ///////////////
echo '<iframe class="iframe" name="my_iframe" src="upload_file.php"></iframe>';

php file upload with mysql filename update

I am trying to combined these two script (a file upload) and (a mysql update) so that the image file is both uploaded to the correct folder and the file path is then updated in the mysql database. I know the $sql update query is wrong and thats where my trouble is. Any help would be great.
//db connection
require "connect.db.php";
if ((($_FILES["file"]["type"] == "image/gif")
|| ($_FILES["file"]["type"] == "image/jpeg")
|| ($_FILES["file"]["type"] == "image/pjpeg"))
&& ($_FILES["file"]["size"] < 20000))
{
if ($_FILES["file"]["error"] > 0)
{
echo "Return Code: " . $_FILES["file"]["error"] . "<br />";
}
else
{
echo "Upload: " . $_FILES["file"]["name"] . "<br />";
echo "Type: " . $_FILES["file"]["type"] . "<br />";
echo "Size: " . ($_FILES["file"]["size"] / 1024) . " Kb<br />";
echo "Temp file: " . $_FILES["file"]["tmp_name"] . "<br />";
if (file_exists("upload/" . $_FILES["file"]["name"]))
{
echo $_FILES["file"]["name"] . " already exists. ";
}
else
{
move_uploaded_file($_FILES["file"]["tmp_name"],
"upload/" . $_FILES["file"]["name"]);
echo "Stored in: " . "upload/" . $_FILES["file"]["name"];
}
}
}
else
{
echo "Invalid file";
}
// update data in mysql database
$sql="UPDATE `characters` SET ch_image='/upload/$_FILES["file"]["name"]' WHERE ID='$id'";
$result=mysql_query($sql);
// if successfully updated.
if($result){
echo "Successful";
echo "<BR>";
echo "<a href='test.html'>View result</a>";
touch('../file.html');
clearstatcache();
}
else {
echo "Whoops: " . mysql_error(); ;
}
mysql_close();
?>
change $sql to this
$sql="UPDATE `characters` SET ch_image='/upload/" . $_FILES['file']['name'] . "' WHERE ID='$id'";
