move file name with unique id from new folder to SQL database - php

Question

I've looked around and haven't found particularly what I'm after.
I have quite a few forms with text input and file uploads.
I've figured how to upload a file, give it a unique ID and get it into my web server folder. Pretty smooth sailing. However, I would like to also get that fancy new ID into my MySQL database.
I've separated my upload.php page with text forms going to the database
<?php
//Connecting and Sending data to the database follows
$dbc = mysqli_connect('localhost', 'root', 'root', 'surfboardhub')
or die('Error connecting to MySQL server');
//Get values from
$location = "";
$price = "";
$thick = "";
$width = "";
$height ="";
$model = "";
$brand = "";
$email = "";
$category = "";
if(isset($_POST['location'])){ $location = $_POST['location']; }
if(isset($_POST['price'])){ $price = $_POST['price']; }
if(isset($_POST['thick'])){ $thick = $_POST['thick']; }
if(isset($_POST['width'])){ $width = $_POST['width']; }
if(isset($_POST['height'])){ $height = $_POST['height']; }
if(isset($_POST['model'])){ $model = $_POST['model']; }
if(isset($_POST['brand'])){ $brand = $_POST['brand']; }
if(isset($_POST['email'])){ $email = $_POST['email']; }
//if(isset($_POST['image'])){ $imagename = $_POST['imagename']; }
//if(isset($_POST['mime'])){ $mime = $_POST['mime']; }
$query = "INSERT INTO uploads (location, price, thick, width, height, model, brand, email,category)
VALUES ('$location', '$price','$thick','$width','$height', '$model', '$brand', '$email','$category')";
$result = mysqli_query($dbc,$query)
or die('Error querying database.');
mysqli_close($dbc);
and then my bit to get the file to its new location in my web server.
$name = $_FILES['image']['name'];
$extension = strtolower(substr($name, strpos($name, '.') + 1));
$type = $_FILES['image']['type'];
$tmp_name = $_FILES['image']['tmp_name'];
if (isset($name)) {
if (!empty($name)) {
if (($extension=='jpg'||$extension=='jpeg'||$extension=='png'||$extension=="gif")&&$type=='image/jpeg'||$type=='image/png'||$type=='image/gif') {
$location = 'uploads/';
$location = $location . uniqid();
if (move_uploaded_file($tmp_name, $location.$name)) {
echo 'uploaded!';
}
else {
echo 'There was an error.';
}
} else {
echo 'File must be jpg/jpeg, png, or gif.';
}
} else {
echo 'Please choose a file';
}
}
?>
Basically, I need to get that new unique ID to go to where the text information is going, because they're all being submitted at once. And I'd like to be able to figure out who uploaded what if need be. If it didn't have a unique ID I can get it to work, but for some reason having that uniqid trips me up. Thoughts? Much obliged.

Save the uniqid() to a PHP variable and then you can use it in more than one place:
First, create an ID:
<?php
$ID = uniqid();
?>
Then, save your file, using your new $ID variable:
<?php
$name = $_FILES['image']['name'];
$extension = strtolower(substr($name, strpos($name, '.') + 1));
$type = $_FILES['image']['type'];
$tmp_name = $_FILES['image']['tmp_name'];
if (isset($name)) {
if (!empty($name)) {
if (($extension=='jpg'||$extension=='jpeg'||$extension=='png'||$extension=="gif")&&$type=='image/jpeg'||$type=='image/png'||$type=='image/gif') {
$location = 'uploads/';
$location = $location . $ID;
if (move_uploaded_file($tmp_name, $location.$name)) {
echo 'uploaded!';
} else {
echo 'There was an error.';
}
} else {
echo 'File must be jpg/jpeg, png, or gif.';
}
} else {
echo 'Please choose a file';
}
}
?>
Then, save your data to the db, including $ID
<?php
//Connecting and Sending data to the database follows
$dbc = mysqli_connect('localhost', 'root', 'root', 'surfboardhub')
or die('Error connecting to MySQL server');
//Get values from
$location = "";
$price = "";
$thick = "";
$width = "";
$height ="";
$model = "";
$brand = "";
$email = "";
$category = "";
if(isset($_POST['location'])){ $location = $_POST['location']; }
if(isset($_POST['price'])){ $price = $_POST['price']; }
if(isset($_POST['thick'])){ $thick = $_POST['thick']; }
if(isset($_POST['width'])){ $width = $_POST['width']; }
if(isset($_POST['height'])){ $height = $_POST['height']; }
if(isset($_POST['model'])){ $model = $_POST['model']; }
if(isset($_POST['brand'])){ $brand = $_POST['brand']; }
if(isset($_POST['email'])){ $email = $_POST['email']; }
//if(isset($_POST['image'])){ $imagename = $_POST['imagename']; }
//if(isset($_POST['mime'])){ $mime = $_POST['mime']; }
$query = "INSERT INTO uploads (ID, location, price, thick, width, height, model, brand, email,category)
VALUES ('$ID', '$location', '$price','$thick','$width','$height', '$model', '$brand', '$email','$category')";
$result = mysqli_query($dbc,$query)
or die('Error querying database.');
mysqli_close($dbc);
?>
