Question

How do I stop the form from submitting on page load or refresh? I’m not worried about parameterizing right now. Thanks in advance!

$firstname = $_POST['firstname']
$lastname = $_POST['lastname']

$sql = ("INSERT INTO table (firstname, lastname) VALUES ('$_POST[firstname]' , ' $_POST[lastname]')");

mysql_query($sql) or die ("Error is: ".mysql_error());


<form name="add-name" id="add-name" method="post" action="/add-name.php">
<button type="submit">Save</button>

<fieldset>
<label>First Name *</label> 
    <input name="firstname" type="text" id="firstname" />
</fieldset>
<fieldset>
<label>Last Name *</label> 
    <input name="lastname" type="text" id="lastname" />
</fieldset>
</form>

if (isset($_POST['firstname'])) {
   $firstname = $_POST['firstname']
   $lastname = $_POST['lastname']

   $sql = ("INSERT INTO table (firstname, lastname) VALUES ('$_POST[firstname]' , '       $_POST[lastname]')");

   mysql_query($sql) or die ("Error is: ".mysql_error());
}
