Example 15-5

As previously printed, there were problems with the code (missing quotation marks,
etc.) It is corrected in the examples file on the O'Reilly web and
FTP sites. Use 15-5.php from there.

The correct code NOW READS:

<body>
<h1>Phone List</h1>

<?php
$dd = odbc_connect('PhoneListDSN','user','password');
// disable autocommit if we're confirming
if ($submit == "Add Listing") {
$start_trans = odbc_autocommit($dd,0);
}

//insert if we've got values submitted
if ($submit == "Add Listing" || $submit == "Confirm") {
$sql = "insert into phone_list ([extension],[name])";
$sql .= "values ('$ext_num','$add_name')";
$result = odbc_exec($dd,$sql);
}
?>

<form method="post" action="phone_trans.php">
<table>
<tr><th bgcolor="#EEEEEE">Extension</th>
<th bgcolor="#EEEEEE">Name</th>

<?php
// build table of extension and name values
$result = odbc_exec($dd,"select * from phone_list");
$cols = array();
$row = odbc_fetch_into($result,$cols);
while ($row) {
if ($cols[0] === $ext_num && $submit != "Confirm") {
?>

<td bgcolor="#DDFFFF"><?= $cols[1] ?></td></tr>

<?php
} else {
print("<tr><td>$cols[0]</td><td>$cols[1]</td></tr>
");
}
$row = odbc_fetch_into($result,$cols);
}

// if we're confirming,make hidden fields to carry state over
// and submit with the "Confirm"button
if ($submit == "Add Listing") {
?>
