【问题描述】：
好的，我让这个页面运行良好，但是我必须怎么做才能显示来自某个字母的数据？
这是我目前得到的代码
<html>
<head>
<title>MySQLi Read Records</title>
</head>
<body>
<?php
//include database connection
include 'db_connect.php';
//query all records from the database
$query = "select * from contacts";
//execute the query
$result = $mysqli->query( $query );
//get number of rows returned
$num_results = $result->num_rows;
//this will link us to our add.php to create new record
echo "<div><a href='add.php'>Create New Record</a></div>";
if( $num_results > 0){ //it means there's already a database record
echo "<table border='1'>";//start table
//creating our table heading
echo "<tr>";
echo "<th>Firstname</th>";
echo "<th>Lastname</th>";
echo "<th>Username</th>";
echo "<th>Action</th>";
echo "</tr>";
//loop to show each records
while( $row = $result->fetch_assoc() ){
//extract row
//this will make $row['firstname'] to
//just $firstname only
extract($row);
//creating new table row per record
echo "<tr>";
echo "<td>{$name}</td>";
echo "<td>{$surname}</td>";
echo "<td>{$mobile}</td>";
echo "<td>";
//just preparing the edit link to edit the record
echo "<a href='edit.php?id={$id}'>Edit</a>";
echo " / ";
//just preparing the delete link to delete the record
echo "<a href='#' onclick='delete_user( {$id} );'>Delete</a>";
echo "</td>";
echo "</tr>";
}
echo "</table>";//end table
}else{
//if database table is empty
echo "No records found.";
}
//disconnect from database
$result->free();
$mysqli->close();
?>
</body>
</html>
我想在正确的字母下放置多个如下所示的条目
<h1>A</h1>
echo "<td>{$name}</td>";
echo "<td>{$surname}</td>";
echo "<td>{$mobile}</td>";
<h1>b</h1>
echo "<td>{$name}</td>";
echo "<td>{$surname}</td>";
echo "<td>{$mobile}</td>";
ECT ECT
我想要实现的是显示所有以 a 然后 b 开头的姓氏
我在这个页面上找到了这段代码http://www.sitepoint.com/forums/showthread.php?303895-Display-Data-Beginning-with-a-Particular-Letter
但是我该如何让这个工作适合我呢？
我是新手（非常），所以任何帮助都很棒，我尝试阅读教程，我发现动手效果更好:)
更新************ ***************
这很好用，但现在它只列出了一行这是我的代码
<html>
<head>
<title>MySQLi Read Records</title>
</head>
<body>
<?php
//include database connection
include 'db_connect.php';
//query all records from the database
$query = " SELECT name,
surname,
mobile,
UPPER (LEFT(surname, 1)) AS letter
FROM contacts
ORDER BY surname";
//execute the query
$result = $mysqli->query( $query );
//get number of rows returned
$num_results = $result->num_rows;
//this will link us to our add.php to create new record
echo "<div><a href='add.php'>Create New Record</a></div>";
if( $num_results > 0){ //it means there's already a database record
echo "<table border='1'>";//start table
//creating our table heading
//loop to show each records
while( $row = $result->fetch_assoc() ){
//extract row
//this will make $row['firstname'] to
//just $firstname only
extract($row);
//creating new table row per record
if (!isset($lastLetter) || $lastLetter != $row['letter'])
{
echo '<h1>', $row['letter'], '</h1>';
$lastLetter = $row['letter'];
echo "{$surname}";
}
}
}else{
//if database table is empty
echo "No records found.";
}
//disconnect from database
$result->free();
$mysqli->close();
?>
</body>
</html>
【问题讨论】：
-
您想在同一页上列出所有信件，还是要在每页请求或表单请求中列出所有信件？
-
都一样，但必须在自己的标题下:)
