Code

<form method ="post" action="cartnisya.php">

<table border="0"align="right">

<td>Username:</td>

<td><input type="Text" name="Username"></td>

<td>&nbsp </td>

<td>&nbsp </td>

<td>Password:</td>

<td><input type="Password" name="Password"></td>

<td>&nbsp </td>

<td colspan="2" align="center"><input type="Submit" name=submit" value="Submit"></td>

</table>

</form>

 

it will then go the php code:

CODE:

<html>

<?php

$db = mysql_connect("localhost", "root","");

mysql_select_db("vinnex",$db);

$Username = $_POST['Username'];

echo $Username;

$result = mysql_query("Select TransNo From transaction", $db);

$myrow = mysql_fetch_array($result);

if ($myrow=='')

{

$TransNo='1000';

$sql = mysql_query("Select * From customer where Username='$Username'", $db);

$myrow1 = mysql_fetch_array($sql);

$Username = $myrow1['Username'];

$Firstname = $myrow1['Firstname'];

$Lastname = $myrow1['Lastname'];

$name = $Firstname. " ".$Lastname;

$Date = date('m/d/y');

$sql1 = "INSERT INTO temptransaction (TransNo, Username, Firstname, Date)

  VALUES ('$TransNo', '$Username', '$Firstname', '$Date')";

$result = mysql_query($sql1); //or die(mysql_error());

}

else

{

$sql = mysql_query("Select max(TransNo) maxTransNo From transaction", $db);

$myrow1 = mysql_fetch_array($sql);

$orderno = $myrow1['maxTransNo']+1;

$sql = mysql_query("Select * From customer where Username='$Username'", $db);

$myrow1 = mysql_fetch_array($sql);

$Username = $myrow1['Username'];

$Firstname = $myrow1['Firstname'];

$Lastname = $myrow1['Lastname'];

$name = $Firstname. " ".$Lastname;

$Date = date('m/d/y');

$sql1 = " INSERT INTO temptransaction (TransNo, Username, Firstname, Date)

  VALUES ('$TransNo', '$Username', '$Firstname', '$Date')";

$result = mysql_query($sql1) or die(mysql_error());

It helps to use the [ code ] snips

 

<form method ="post" action="cartnisya.php">
<table border="0"align="right">
   <td>Username:</td>
   <td><input type="Text" name="Username"></td>
   <td>&nbsp </td>
   <td>&nbsp </td>
   <td>Password:</td>
   <td><input type="Password" name="Password"></td>
   <td>&nbsp </td>
   <td colspan="2" align="center"><input type="Submit" name=submit" value="Submit"></td>
</table>
<img src="Vinnex1.jpg">   


</form>

it will then go the php code:
CODE:

<?php
$db = mysql_connect("localhost", "root","");
mysql_select_db("vinnex",$db);
$Username = $_POST['Username'];
echo $Username; // is this necessary in a processing file?
$result = mysql_query("Select TransNo From transaction", $db);
$myrow = mysql_fetch_array($result);
if ($myrow==null) //null is script friendly :]
{
   $TransNo='1000';
   $sql = mysql_query("Select * From customer where Username='$Username'", $db);
   $myrow1 = mysql_fetch_array($sql);
   $Username = $myrow1['Username'];
   $Firstname = $myrow1['Firstname'];
   $Lastname = $myrow1['Lastname'];
   $name = "$Firstname $Lastname"; //first last
   $Date = date('m/d/y');
   $sql1 = "INSERT INTO temptransaction (TransNo, Username, Firstname, Date)
           VALUES ('$TransNo', '$Username', '$Firstname', '$Date')";
   $result = mysql_query($sql1); //or die(mysql_error()); 

// you are inserting data into table: temptransaction, pulled from customer
}
else
{
   $sql = mysql_query("Select MAX(TransNo) AS maxTransNo From transaction", $db); // added as statement
   $myrow1 = mysql_fetch_array($sql);
   $orderno = $myrow1['maxTransNo']+1;
   $sql = mysql_query("Select * From customer where Username='$Username'", $db);
   $myrow1 = mysql_fetch_array($sql);
   $Username = $myrow1['Username'];
   $Firstname = $myrow1['Firstname'];
   $Lastname = $myrow1['Lastname'];
   $name = "$Firstname $Lastname"; //first last
   $Date = date('m/d/y');

// fixed spacing in insert statement primary cause
   $sql1 = "INSERT INTO temptransaction (TransNo, Username, Firstname, Date)
           VALUES ('$TransNo', '$Username', '$Firstname', '$Date')";
   $result = mysql_query($sql1) or die(mysql_error());
}
header("Location: /orderproduct.html"); //added header redirect
?>
<!--// Removed meta refresh... this method should be considered deprecated in html coding xD //-->
<html>
</html>

 

 

The table for your users is "Username" not username correct?
