php変数echoが適切な値でdbに挿入されています

Question

私は変数が$mrnのPHPフォームであります。 $_POST[];メソッドを使用してデータを送信すると、別のページをプルアップし、フォームに入力された内容をエコーし​​てdbテーブルに送信するPHPスクリプトが呼び出されます。私がdbテーブルをチェックすると、フォームに入力され、正常にエコーされた値がdbに挿入される値ではありません。フォーム内の他のすべてのデータは、正しく正常にポストされます。この同じ変数は、いずれのフォームのdbにも正しくポストしません。私はこの投稿similar issueを見ています。私はその機能に慣れておらず、それを読んでいます。

は、ここに私のinsert_recordsが

<?php 
    $page_title = 'Insert Outcomes Data'; 
    include('php_includes/header.html'); 

    // Connect to the database 
    include_once("php_includes/db_connect.php"); 

    // Gather the posted data into local variables 
    $mrn = $_POST['mrn']; 
    $add_hosp_dispo = $_POST['add_hosp_dispo']; 
    $date_alt_lvl_cr_sts = $_POST['date_alt_lvl_cr_sts']; 
    $actual_discharge_time = $_POST['actual_discharge_time']; 
    $actual_discharge_date = $_POST['actual_discharge_date']; 
    $gcs_outcome = $_POST['gcs_outcome']; 

    // Get user IP Address 
    $ip = preg_replace('#[^0-9.]#', '', getenv('REMOTE_ADDR')); 

    // Form data error handling 
    if($mrn == ""){ 
     echo "The form submission is missing data."; 
    } else { 
     // End form data error handling 
     $sql = "INSERT INTO nys_outcome_info (

SQLキーワード（WHEREなど、FROM、SELECT）大文字と小文字を区別しませんが、PHPが、多くの場合、すべて大文字で書かれています。一部の設定では、テーブル名とカラム名で大文字と小文字が区別されます。あなたの場合、MRNはMRNでなければなりません。だからこそ、あなたはデータを挿入していないのです。
