从表中选择“特定名称”或“全部”

Question

现在我从表中调用taman section，我只想调用特定的taman部分或者调用表中的所有taman section，我怎么能这样做？ 贝娄是我的代码：
post.php中：

<select name="taman">
<option value="taman1">Taman1</option>
<option value="tamanA">TamanA</option>
<option value="*">ALL</option>
</select>

select.php

$taman = $_POST["taman"]; //this taman are post from post.php,I have tried put value * to this $taman, but still cannot.

$qry="SELECT cusinfo.* FROM cusinfo 
                        WHERE cusinfo.TAMAN_SECTION = '$taman'
                        ";

Answer 1

你也可以试试这个

$taman = $_POST["taman"]; 
if($taman=='*'){
$qry="SELECT cusinfo.* FROM cusinfo ";                   
}
else{
$qry="SELECT cusinfo.* FROM cusinfo WHERE cusinfo.TAMAN_SECTION = '".$taman."'"; 
}

此处无需更改html选项。
