Question

我喜欢将链接放到html表中，这些链接是从mysql表中查询的

------------------------------
item Number |  Item purchased
------------------------------
1           |  a vase
2           |  a candle

etc.....
10
------------------------------
           <<1,2,...100|next>>

这对我来说很难。有人可以给我一个想法或图书馆让我开始吗？非常感谢你

Answer 1

如果这对你来说太难了，我建议你使用CMS，直到你的脚湿透。那里有很多。 Wordpress，Drupal，Symphony仅举几例。

Answer 2

如果您使用像AlientWebguy建议的CMS，您将永远不会学习......我假设您在这里学习。你应该从教程开始，因为这是非常基本的东西。

但要完成你想做的事 - 如果我是新手 - 这就是我要做的。我不打算给你你的代码，但它肯定足够接近你应该能够解决它。

我会创建一个名为functions.php的文件，其中包含以下内容：

<?PHP
// these are freebies.  You don't need to understand them yet.
function sqlarr($sql, $numass=MYSQL_BOTH) {
    // MYSQL_NUM  MYSQL_ASSOC  MYSQL_BOTH
    $got = array();
    $result=mysql_query($sql) or die("$sql: " . mysql_error());                             

    if(mysql_num_rows($result) == 0)
        return $got;
    mysql_data_seek($result, 0);
    while ($row = mysql_fetch_array($result, $numass)) {
        array_push($got, $row);
    }
    return $got;
} 

// Sql fetch assoc
function sqlassoc($sql){
    $query = mysql_query($sql) or die("$sql:". mysql_error());
    $row = mysql_fetch_assoc($query);
    return $row;
}

function sqlrow($sql){
    $query = mysql_query($sql) or die("$sql:". mysql_error());
    $row = mysql_fetch_row($query);
    return $row;
}

function sqlquery($sql){
    $query = mysql_query($sql) or die("$sql:". mysql_error());
    return $row;
}

?>

然后在我要输出数据的文件上，我会提出以下内容：

    <?PHP  include('./functions.php'); 
    // It sounds like you are already connected to your database, so I'm going to skip that.  If you need it, add a comment.
    $sql = "SELECT `colNames`, `colName2` FROm `tableName` WHERE `col` = 'condition' ";
    // obviously change this to your names, such as `itemNumber`
    $results = sqlarr( $sql ); // Now results is going to automatically contain a 2D array.  
    echo '<pre>'; print_r( $results ); echo '</pre>';
    /* this is just to show you what is happening so far.  You should get in the habit of using things like this to debug.  A lot of people prefer var_dump instead of print_r.  I use both because var_dump is harder to read.
    // Result should be returning something like this:
    // array(
            [0] => array(
                    [0] => 'ABC123',
                    ["itemNumber"] => 'ABC123',
                    [1] => 'http://www.abc.com',
                    ["link"] => 'http://www.abc.com' ),
            [1] => array( ... )
            )
    // the first level - the [0] => array(  or the [1] => array( part - corresponds to a row in your database
    // so now we need a way to filter through those rows.  Look up php.net/for or php.net/foreach to see how to accomplish that.  A lot of people use php.net/while too, but I don't prefer that personally. */
    ?>
    <html>
    <body>
    <table>
    <?PHP
    foreach( $results as $row ){  // this is turning $result[0] => array(  into $row.  So now we can access $result[0]['linkName'] as $row['linkName']
       echo '<tr><td>'.$row['linkName'].'</td></tr>';
    }  // foreach $row - dont forget to close your curly bracket.  Good practice is to always close it as soon as you open it, and to put a comment after it like I just did letting you know what it goes to
    ?>
    </table>
    </body>
    </html>

如果这里没有任何意义，请发表评论。我很乐意解释。
