html – Online Shop PHP does not add the form to the SQL database

I've been trying this for days, but I could not achieve anything
I want the addprodect.php page to add the inputs to the "coffee" database

<? php
$ current_url = urlencode ($ url = "http: //". $ _ SERVER['HTTP_HOST'], $ _ SERVER['REQUEST_URI']);
if (isset ($ _ POST.)['addproduct'])) {
$ name = ($ _ POST['Name']);
$ cost = ($ _ POST)['Price']);
$ ID = ($ _ POST['ID']);
// $ size = ($ _ POST['size']);
$ Quantity = ($ _ POST)['Quantity']);
$ description = ($ _ POST['description']);
$ image = ($ _ POST['fileToUpload']);
$ link = mysqli_connect ("localhost", "", "");
mysqli_select_db ($ link, "coffee");
$ Query = "INSERT INTO Product (ID, Name, Image, Price, Quantity, Description) VALUES (& # 39; $ ID & # 39 ;, $ 39 & # 39 ;, & # 39; image & # 39; ;, & # 39; $ cost & # 39 ;, & # 39; $ Quantity & # 39 ;, & # 39; $ description & # 39;) & quot;
if (mysqli_query ($ link, $ query)) {
Echo "
The article will be added successfully, thanks. 

";
} else {
header (& # 39; errorAddingNewRecord (Item) & # 39;);
}
mysqli_close ($ link);
}
?>

Email Marketing for Affiliate Marketing

I am interested in starting affiliate marketing. I think most of us start with e-mail marketing and then build ourselves up through blogs and other media. What is the best way to get stared? How do I start for e-mail marketing? MaillChimp and the like seem to have inappropriately expensive plans with very few legitimate e-mails. Does not sound like a good idea. With how many e-mails should I start if I have a database? Which tools help me to get started?

apt – update system seems to be broken

Today I ran my usual apt update and apt upgrade commands and I had a problem. Whenever I enter sudo apt update, I am asked for my password as usual, but then nothing happens. The cursor flashes and then becomes stationary. However, the update process will not start.

I tried sudo dpkg –configure -a, but nothing has changed. Switching the source server also appears to be flawed, and the change process keeps the software and the update utility on hold.

I run Ubuntu 18.10 with kernel 5.0.5. The problem is still here on 5.0.1 and 4.20.0. Any idea ?

Integration – The integral of a radius function 1 / (r (x) * e ^ r (x))

I estimate a radius function with quadratic isoparametric line elements as follows:

d1 = x1 * 0.5 * x * (x-1) + x1 * (x + 1) * (x-1) + x3 * 0.5 * x * (x + 1)

d2 = y1 * 0.5 * x * (x-1) + y1 * (x + 1) * (x-1) + y3 * 0.5 * x * (x + 1)

Where x1, y1 … -> are nodes of a quadratic element with three nodes.

By finding a source point I can create a radius function, eg.

r (x) = sqrt ((d1-xsp) ^ 2 + (d2-ysp) ^ 2)

Where xsp, ysp … -> are nodes from a localized source point.

Of course, I also need the Jakobianer of this transformation:

d1j = x1 * (x-0.5) + x2 * (- 2 * x) + x3 * (x + 0.5)

d2j = y1 * (x – 0.5) + y2 * (- 2 * x) + y3 * (x + 0.5)

JAC = sqrt (d1j ^ 2 + d2j ^ 2)

The question:

What would be the integral or which numerical method should be used to solve the following integral if the source point is inside the quadratic isoparametric element:

Int N2 * JAC / (r (x) * e ^ r (x)) from -1 to 1

With:

N2 = (x + 1) * (x-1)

xsp = x2

ysp = y2

The integral becomes singular, as the radius goes to zero. I also think that this might be related to the exponential integral, but I can not apply it because the radius is a polynomial function. I have tried many things, but the standard numeric integration does not work and also mathematica fails.

Any guess, what an integral is that? or what should you try to solve it?

thanks in advance and apologies for the long question.

What are the best settings for my Nikon P520 for everyday outdoor shooting?

If you shoot manually without understanding the metering and exposure, it will be difficult for you.

There are no universal settings – all you have to do is adjust to the light you have and play within the Iso / Shutter / Shutter sandbox, depending on the look you want to get.

If you just want to record and drive your camera and for some reason really do not want to use full auto modes, go to P mode or Av mode with 400ISO. Change the aperture as you see fit. If you do not pay attention to your shutter speeds, you may find it difficult to make sure they are within your grip range.

Windows 7 – Samsung Galaxy S7 Defective screen workaround

I hope that's not a double question, if so, I apologize. I have a Samsung Galaxy S7 with a broken screen. To define this, it is totally black (nothing appears) and it does not respond to touch. I have a Bitcoin wallet with a decent amount on the phone, but I was stupid and did not support it. The phone has turned off file transfer (I do not know how, I've always thought I've activated it since I've often transferred files), and I need a way to get the Bitcoin wallet out of a computer, monitor, or maybe on accessing another phone repairing the phone is not an option as 1) I already have a new one and 2) the repair would cost me more than is in the wallet. Any help would be appreciated. Thank you in advance. 🙂

How do I find a particular slide with a specific layout in Google Slides?

I have a 38 slide presentation. In examining the master theme, I can see that there is 1 slide with a particular Big Number layout. However, I do not see any slides that use this layout. I've gone through every slide and made sure each one uses the right layout. How can I find this seemingly "phantom" slide so I can either delete it or change it to use the correct layout?

Algorithms – Invariant determination of a cycle

Suppose we execute line 3 the first time you visit a node, and if you are working with directed graphs, this algorithm is not correct (look at what happens to a cross-border recognized by DFS).

Suppose you work with undirected graphs:

The missing part of your argument is the "so" part; Why does the existence of two such nodes imply the existence of a cycle?

To find out the proof, I propose to categorize what kinds of edges may be present in the search tree for a non-directional diagram: tree edges? Leading edge? Trailing edges / transverse edges? Then you categorize what kind of edge caused you to visit x[x] was true. What must the search tree look like?
