Issues: PHP Forms -Clearing

Posted on 16th Feb 2014 by admin

I've tried looking online before actually asking for help, but I've been looking for about the past 3-5 hours and have found nothing that'll help me.

This is a project for school, and well I have to use Access as a database. I am using PHP for coding, and I'm fairly new to PHP. Now for the problem...

When I type in a Name in my Text Field all is good, I hit submit it works, if I hit reset it resets. My issue happens after I hit submit once the item is added, then if I refresh the page the item is added again, and it happens as many times as I hit refresh. I've tried numerous ways to make my text fields clear. I'm not coming up with anything. I started out having two files a PHP and HTML, I combined them hoping I could figure out a way to fix this, but to no avail.

If you look at my code you'll find that "odbc_exec($conn,$input);" is missing I took it out cause I have no idea where to put it, or what to do with it, or how to clear the fields upon having that executed.

If anyone could help me even the tiniest bit that'd be great




Code: <?php
$conn=odbc_connect('database','','');
if (!$conn)
{exit("Connection Failed: " . $conn);}

$Name = $_POST["Name"];
$Submit = $_POST["Submit"];
$Reset = $_POST["Reset"];

$input="INSERT INTO Registry (FirstName) VALUES('$Name')";

$sql="SELECT * FROM Registry";
$rs=odbc_exec($conn,$sql);
?>

<html>
<body>
<form name="TestForm" method="POST" action="<?php echo $_SERVER['PHP_SELF'] ?>">

Name: <input type="text" name="Name" maxlength=50/>
<p>

<input type="submit" name="Submit" value="Submit">
<input type="reset" name="Reset" value="Reset">
</form>
</body>
</html>

<?php
if (!$rs)
{exit("Error in SQL");}

echo "<table><tr>";
echo "<th>FirstName</th>";
echo "<th>LastName</th></tr>";

//Writes Table Values
while (odbc_fetch_row($rs))
{
$firstname=odbc_result($rs,"FirstName");
$lastname=odbc_result($rs,"LastName");
echo "<tr><td>$firstname</td>";
echo "<td>$lastname</td></tr>";
}

odbc_close($conn);
echo "</table>";
?>
