分类MySQL数据到单独的HTML表格？ [英] Categorizing mysql data into seperate html tables?

问题描述

我有一个数据库查询，返回项ID，ITEMNAME，类别ID和类别名称。我被他们的类别名称试图组我的结果到单独的HTML表格所以最终的结果看起来是这样的：

I have a database query that returns ItemID, ItemName, CategoryID and CategoryName. I am trying to group my results into separate html tables by their CategoryName so the end result looks something like this:

 ________________________________
|____________CategoryName________|
| ItemName |                     |
|__________|                     |
| ItemName |                     |
|__________|                     |
| ItemName |                     |
|__________|_____________________|
 ________________________________
|____________CategoryName________|
| ItemName |                     |
|__________|                     |
| ItemName |                     |
|__________|                     |
| ItemName |                     |
|__________|_____________________|

目前我能输出我的数据到一个表，但我不确定如何去休息。
看来我有更好的ASCII艺术技能比PHP技能：/

Currently I can output my data into one table, but I am uncertain how to go about the rest. Seems i have better ascii art skills than php skills :/

推荐答案

的HTML是关闭的，但这应该让你开始：

The HTML is off, but this should get you started:

<?php

$query = 'SELECT CategoryID, CategoryName, ItemID, ItemName
FROM tableName
ORDER BY CategoryID';

$result = mysql_query($query);
if (!$result || mysql_num_rows($result) == 0) {
    echo "No rows found";
    exit;
}

$lastCatID = 0; //or some other invalid category ID

while ($row = mysql_fetch_assoc($result)) {
    if($lastCatID != $row['CategoryID']) {
        //starting a new category
        if($lastCatID != 0) {
            //close up previous table
            echo '</table>';
        }

        //start a new table
        echo '<table><th><td colspan="2">Category '
                . $row['CategoryName'] .'</td></th>';
        $lastCatID = $row['CategoryID'];
    }

    echo '<tr><td>' . $row['ItemName'] . '</td><td></td></tr>';
}

if($lastCatID != 0) {
    //close up the final table
    echo '</table>';
}

mysql_free_result($result);
?>
