PHP を学習するための Web サイトを構築しており、メンバーシップ アプリを構築しました。
これは、ユーザーがログインしたときに設定したユーザー Cookie を取得するためのコードです。次に、関連付けられている biz というビジネス ID を取得し、companyという名前のテーブルで、bizに等しい ID を持つビジネスのすべての詳細を検索します。: (ところで、私は mysql を使用していることを知っていますが、アプリを完成させるときに、PDO または mysqli に切り替えます)
<?
$auth = $_COOKIE["auth"];
if ($auth != "1"){
header("Location: ./signin.php");
}
//Grab all the cookies
$firstname = $_COOKIE['firstname'];
$id = $_COOKIE['id'];
$fname = ucwords($_COOKIE['firstname']);
$lname = ucwords($_COOKIE['lastname']);
$email = $_COOKIE['email'];
$city = ucwords($_COOKIE['city']);
$biz = $_COOKIE['biz'];
if(!empty($biz)){
$donthaveabizyet = "false";
}
else{
include("./config.php");
$result = mysql_query("SELECT * FROM company WHERE id = '$biz'") or mysql_error();
while($row = mysql_fetch_array($result))
{
$business_name = $row['name'];
$business_phone = $row['phone'];
$business_website = $row['website'];
$business_phone = $row['phone'];
$business_cat1 = $row['cat1'];
$business_cat2 = $row['cat2'];
$business_cat3 = $row['cat3'];
$business_subcat1 = $row['subcat1'];
$business_subcat2 = $row['subcat2'];
$business_subcat3 = $row['subcat3'];
$business_email = $row['email'];
$business_product1 = $row['product1'];
$business_product2 = $row['product2'];
$business_product3 = $row['product3'];
$business_product4 = $row['product4'];
$business_product5 = $row['product5'];
$business_product6 = $row['product6'];
$business_product7 = $row['product7'];
$business_noaddress = $row['noaddress'];
$business_address = $row['address'];
$business_address2 = $row['address2'];
$business_zipcode = $row['zipcode'];
$business_city = $row['city'];
}
$result = mysql_query("SELECT * FROM company_secondary WHERE company_id = '$biz'") or mysql_error();
while($row = mysql_fetch_array($result))
{
$business_description = $row['company_description'];
$business_since = $row['phone'];
$business_logo = $row['logo'];
$business_since = $row['since'];
$business_smoking = $row['smoking'];
$business_delivery = $row['delivery'];
$business_alcohol = $row['alcohol'];
$business_kids = $row['kids'];
$business_wheelchair = $row['wheelchair'];
$business_twitter = $row['twitter'];
$business_facebook = $row['facebook'];
$business_youtube = $row['youtube'];
$business_creditcards = $row['creditcards'];
$business_outdoor = $row['outdoor'];
$business_featured = $row['featured'];
}
}
?>
ここで、ユーザーのビジネス ID が 0 の場合は claim.php へのリンクを表示します。ユーザーのビジネス ID が設定されている場合は、ビジネスの名前を表示します。
<?php
if($donthaveabizyet != "false")
{
echo "<br/><br/>You haven't claimed a business yet. <a href='claim.php'>Click here to claim one now.</a>";
}
else
{
echo $business_name;
}
?>
残念ながら、$business_name は表示されておらず、エラーはNotice: Undefined variable: business_name
です。business_name が設定されていないのはなぜですか?
すべての助けに感謝します!!
