PHPを追加するまで完全に表示されるメンバー登録フォームがあります。phpコードが追加されると、フォームは完全に消えます。私はすべてを試しましたが、この段階では新鮮な目が必要だと思います。どんな助けでも大歓迎です。乾杯。

<?php

エコーステートメントはif（$ _POST ['registerbtn']）{}ブロック内にあります。つまり、フォームが送信されない場合、フォームは表示されません。

PHPコードにエラーがあり、何も実行できません。

エラーを確認するには、PHPLintなどでコードを実行することをお勧めします。

また、読みやすく、保守しやすい方法でコードを構造化することを検討することもできます。

たとえば、ネストされたifステートメントをすべて回避して、次のように記述することができます。

if (!$getuser) {
   $errormsg = "You must enter username to register.";
}
else if (!$getemail) {
   $errormsg = "You must enter email to register.";
}

編集：Armon Toubmanが述べたように、フォームは関連データがページに投稿されている場合にのみ表示されます。フォームをifステートメントの外に移動する必要があります。以下のコードを参照してください。
