I'm creating this web page for this class that I'm in and for it I need to concatenate two separate HTML form inputs with a space in between and insert them into a MySQL database. Specifically I ask the user for their first name and their last name in separate HTML form inputs and I have to concatenate those two input into a full name with a space in between (or else "Bob" and "Ross" concatenated would be "BobRoss" instead of "Bob Ross"). I don't know where to start when doing that. Also I need to check that the full name isn't already in the database before inserting it into the database, but I'm already doing that with the first name and last name so that shouldn't be too hard.
Here is the HTML page with the form inputs:
<html>
<head>
<link rel="stylesheet" href="Site.css">
<?php include("Header.php"); ?>
</div>
</head>
<body>
<div id="main">
<h1>About</h1>
<form action="Insert.php" method="post">
<p>First name:</p><input type="text" name="firstname"><br>
<p>Last name:</p><input type="text" name="lastname"><br>
<p>Age:</p><input type="text" name="age"><br>
<input type="submit">
</form>
<?php include("Footer.php");?>
</div>
</body>
</html>
And here is the PHP page where it inputs the data into the database. Currently I'm inputing the user's first name, last name, and age, but I need to concatenate the first and last name and make sure it isn't in the database and then insert it into the database and I haven't done that. Currently I make sure that the first name is unique, I make sure that the last name is unique, but I don't care whether the age is unique or not.
