【问题描述】：
我使用客户表格和采购表格收集数据，然后将其存储在db_clientData.php 和db_purchaseData.php 上，我将其写入数据库表客户和采购。
然后在db_salesReport.php 文件上，我访问这两个表，但它不显示新存储的信息，而只显示我手动估算的旧行（不是通过使用表单）。
为什么不显示新信息？
谁能告诉我我错过了什么？
新客户表格：
<form action="db_clientData.php" method="post">
First Name: <input type='text' name='client_fname' /><br />
Last Name: <input type='text' name='client_lname' /><br />
City: <select name='client_city'>
<option>Prishtine</option>
<option>Mitrovice</option>
<option>Peje</option>
<option>Gjakove</option>
<option>Ferizaj</option>
<option>Prizren</option>
</select><br />
Gender: <select name='client_sex'>
<option>F</option>
<option>M</option>
</select><br />
Username(3-10 characters): <input type='text' name='client_username' /><br />
Password(3-10 characters): <input type='password' name='client_pass' /><br />
<input type='submit' value='Submit' />
<input type="reset" value="Clear" />
购买表格：
<form action="db_purchaseData.php" method="post">
Book: <select name='purchase_book'>
<option>Darka e gabuar</option>
<option>Populli i ndalur</option>
<option>Bageti e Bujqesi</option>
<option>Fjala gdhend gurin</option>
<option>Shtiegje Poetike</option>
<option>Bashkohesit</option>
<option>Colored Water</option>
<option>Selected Poems</option>
<option>Olivion Favorites</option>
</select><br />
Amount: <input type='number' name='purchase_amount' /><br />
<input type='submit' value='Submit' />
<input type="reset" value="Clear" />
</form>
存储新客户：
<?php
include('db_login.php');
// Connect
$connection = mysql_connect($db_host, $db_username, $db_password);
if (!$connection){
die("Could not connect to the database: <br />". mysql_error( ));
}
// Select the database
$db_select = mysql_select_db($db_database);
if (!$db_select){
die ("Could not select the database: <br />". mysql_error( ));
}
$fname = isset($_POST['client_fname']) ? $_POST['client_fname'] : null;
$lname = isset($_POST['client_lname']) ? $_POST['client_lname'] : null;
$city = isset ($_POST['client_city']) ? $_POST['client_city'] : null;
$sex = isset($_POST['client_sex']) ? $_POST['client_sex'] : null;
$username = isset ($_POST['client_username']) ? $_POST['client_username'] : null;
$pass = isset ($_POST['client_pass']) ? $_POST['client_pass'] : null;
$sql = "INSERT INTO clients (client_fname, client_lname, client_city, client_sex, client_username, client_pass) VALUES ('$fname','$lname','$city','$sex','$username',MD5('$pass'))";
mysql_query($sql, $connection);
mysql_close();
echo "Data stored on database.";
?>
<a href="db_testAuth.php"><br><input type='button' value='Log In'></a>
存储新购买：
<?php
include('db_login.php');
// Connect
$connection = mysql_connect($db_host, $db_username, $db_password);
if (!$connection){
die("Could not connect to the database: <br />". mysql_error( ));
}
// Select the database
$db_select = mysql_select_db($db_database);
if (!$db_select){
die ("Could not select the database: <br />". mysql_error( ));
}
$bookname = isset($_POST['purchase_book']) ? $_POST['purchase_book'] : null;
$bookamount = isset($_POST['purchase_amount']) ? $_POST['purchase_amount'] : null;
$sql = "INSERT INTO purchases (purchase_book, purchase_amount) VALUES ('$bookname','$bookamount')";
mysql_query($sql, $connection);
mysql_close();
echo "Data stored on database.";
?>
<a href="db_salesReport.php"><br><input type='button' value='Sales Report'></a>
调用 db_salesReport.php 上的数据：
<body>
<p>Sales Report</p>
<table border="2">
<tr>
<th>Client ID</th>
<th>Name</th>
<th>Surname</th>
<th>Username</th>
<th>Purchase ID</th>
<th>Book title</th>
<th>Amount</th>
</tr>
<?php
//Include our login information
include('db_login.php');
// Connect
$connection = mysql_connect($db_host, $db_username, $db_password);
if (!$connection){
die("Could not connect to the database: <br />". mysql_error( ));
}
// Select the database
$db_select = mysql_select_db($db_database);
if (!$db_select){
die ("Could not select the database: <br />". mysql_error( ));
}
// Assign the query
$query = "SELECT clients.client_id, clients.client_fname, clients.client_lname, clients.client_username, purchases.purchase_id, purchases.purchase_book, purchases.purchase_amount from clients,purchases where clients.book_id=purchases.book_id;";
// Execute the query
$result = mysql_query($query);
if (!$result){
die ("Could not query the database: <br />". mysql_error( ));
}
// Fetch and display the results
while ($row = mysql_fetch_array($result, MYSQL_ASSOC)){
$client_id = $row["client_id"];
$client_fname = $row["client_fname"];
$client_lname = $row["client_lname"];
$client_username = $row["client_username"];
$purchase_id = $row["purchase_id"];
$purchase_book = $row["purchase_book"];
$purchase_amount = $row["purchase_amount"];
echo "<tr>";
echo "<td>$client_id</td>";
echo "<td>$client_fname</td>";
echo "<td>$client_lname</td>";
echo "<td>$client_username</td>";
echo "<td>$purchase_id</td>";
echo "<td>$purchase_book</td>";
echo "<td>$purchase_amount</td>";
echo "</tr>";
}
// Close the connection
mysql_close($connection);
?>
</body>

JakeGould 那些人帮助我的东西给了我一个推动我几乎完成我的项目的动力。我现在剩下的就是这个问题，因为我尝试了我所知道的一切但没有工作。因此，我认为一些建议可能会有所帮助。
