What exactly is missing?

You already know how to verify if the address is valid. If it is, insert it into the table (as you already know), if it doesn't, do something like this:

Code:

if (!valid) {
$error = "Invalid address.";
}

// and maybe in the html
<**php if ($error) { echo $error; } **>

// i changed ? to ** since cloudflare was blocking the code with the real php tag

An working example:

Code:

<**php

if (isset($_POST["address"])) {
   $address = $_POST["address"];
   if (checkAddress($address) {
   addAddressToDb($address);
   } else {
   $error = "Invalid address.";
   }
} else {
   $error = "Please input an address.";
}

**>

   Add Address

   <**php if (isset($error)) { echo $error; } **>


// again, i changed ? to ** since cloudflare was blocking the code with the real php tag

And then, the addAddressToDb($address) function simply receives the address as a parameter and add it to the database with the INSERT sql command.

Or something like this.

I have a small programm where i take in a users Bitcoin address as input and than insert it into mysql database.

user inputs bitcoin address and clicks submit button

which than validates the bitcoin address and if address is valid- he can click submit button and gets redirected to a different part of my site- and if address is valid it gets added to mysql database.

If input isn't valid - display an error message

Im using php for everything

I just dont know how to put this together into a working project
