### 制作しているシステム

PHPで自動販売機のシステムを制作
管理、在庫、購入履歴の３つのデータベースに管理しています


### 発生している問題

```
<tr class = "status_false">とし、status_buttonが非公開→公開(hidden value 1)の時のif文の条件の一つとして
 background-color:gray;を指定しているのですが、value１でない商品も全て背景色が変わってしまいます。

### 試したこと
phpのif文の中にさらにif文を加え、$drink_idと比較してみた
if($drink_id === 'drink_id')
else以降、valueが0の時に同じように背景色白を指定してみた

### 問題の発生した環境

PHP  Version 5.3.29

### 制作しているシステム

PHPで自動販売機のシステムを制作
管理、在庫、購入履歴の３つのデータベースに管理しています


### 発生している問題

```
<tr class = "status_false">とし、status_buttonが非公開→公開(hidden value 1)の時のif文の条件の一つとして
 background-color:gray;を指定しているのですが、value１でない商品も全て背景色が変わってしまいます。

### 試したこと
phpのif文の中にさらにif文を加え、$drink_idと比較してみた
if($drink_id === 'drink_id')
else以降、valueが0の時に同じように背景色白を指定してみた

### 問題の発生した環境
