我有 2 个表,第一个是材料,第二个是数据库中的类别。
材料表包含以下内容:
___________________________________________________________________________
|id |type|color|supplier|name |image |category_id|material_price_30|
|___|____|_____|________|_______|___________|___________|_________________|
|1 |Gran|Black| |Angola |angola.jpg |3 |100 |
|2 |Gran|Blue | |Emerald|emerald.jpg|0 |120 |
|3 |Marb|Black| |Galaxy |galaxy.jpg |8 |135 |
|4 |Marb|White| |Visag |visag.jpg |1 |115 |
|5 |Quar|White|Sill Co |Orissa |orissa.jpg |5 |106 |
类别表包含以下内容:
_____________________________
|id |name|thickness|price |
|___|____|_________|________|
|1 |1 |30mm | 169|
|2 |2 |30mm | 244|
|3 |3 |30mm | 280|
|4 |4 |30mm | 316|
|5 |5 |30mm | 347|
|6 |6 |30mm | 411|
|7 |7 |30mm | 496|
|8 |8 |30mm | 544|
|9 |9 |30mm | 612|
|10 |10 |30mm | 689|
|11 |11 |30mm | 775|
我一直在使用以下脚本从 MATERIALS 中检索所有图像,但现在还需要从 CATEGORY 中添加价格,只是不知道如何。MATERIALS 中的 category_id 应该从 CATEGORY 表中识别类别的价格。
你们能帮我把它们2连接在一起吗?
这是我已经使用了一段时间的脚本:
<?php
$samples = "SELECT * FROM materials WHERE materials.type = :cat and materials.supplier = '$supplier'";
$res = $db->prepare($samples);
$res->execute(array(':cat' => $category));
$count = $res->rowCount();
if($count > 0)
echo "
<section class=\"border mar_t_40\">
";
while ($row = $res -> fetch()){
$postimggranite = $row[image];
$postidgranite = $row[id];
$folder = $row[type];
$folder = strtolower($folder);
$supplier = strtolower($supplier);
$category_id = $row[category_id];
print<<<END
<span class="grid white_back mar_l_30">
<a class="fancybox" href="$img_path/$folder/$supplier/large/$postimggranite" rel="group[$postidgranite]" title="$row[name]"><img alt="$row[name]" src="$img_path/$folder/$supplier/small/$postimggranite" width="100" height="100">$row[name]</a>
</span>
END;
}
echo "<div class=\"clearfloat\"></div></section>";
?>
