需要在 PHP class 中创建 return 无序列表
Need to create and return unordered list in PHP class
我正在尝试创建如下列表:
<option value="1">Location 1</option>
<option value="2">Location 2</option>
<option value="3">Location 3</option>
class 中的 Public 函数应该从 DB 中获取所有值并以上面显示的格式输出结果。这是我的功能:
public function FitArea(){
$sth = $this->db->prepare("SELECT * FROM `delivery_cost` ORDER BY 'id'");
$sth->execute();
$row = $sth->fetch(PDO::FETCH_ASSOC);
$FitLocation = array("id" => $row["id"], "location" => $row["location"], "cost" => $row["cost"]);
return $FitLocation;
}
显然我首先在页面上调用 class,但我不确定我是否正确地完成了其余部分,因为没有发生任何事情。
<?php
require_once("class/class.get.materials.php");
$getMaterials = new Getmaterials();
$FitLocation = $getMaterials->FitArea();
while($FitLocation > 0){
print<<<END
<option value="{$FitLocation['cost']}">{$FitLocation['location']}</option>
END;
}
?>
我刚刚弄好了,对于像我这样的新手,这里是我的详细答案:
Public 函数应如下所示:
public function FitArea(){
$sth = $this->db->prepare("SELECT * FROM `delivery_cost` ORDER BY id");
$sth->execute();
$row = $sth->fetchAll(PDO::FETCH_ASSOC);
$FitLocation = array();
for($i=0;$i<count($row);$i++){
array_push($FitLocation,
array(
"id" => $row[$i]["id"],
"location" => $row[$i]["location"],
"cost" => $row[$i]["cost"],
)
);
}
return $FitLocation;
}
剩下的应该是:
<?php
require_once("class/class.get.materials.php");
$getMaterials = new Getmaterials();
$FitLocation = $getMaterials->FitArea();
foreach($FitLocation as $key => $value){
print<<<END
<option value="{$value['cost']}">{$value['location']}</option>
END;
}
?>
总而言之,自己一个人搞定的感觉真好
感谢大家
