我有一个带有变量$mrn的php形式的变量。当我通过$_POST[];方法提交数据时，会调用php脚本来提取另一个页面并回显表单中输入的内容并将其提交到db表。当我检查db表时，输入到表单并成功回显的值不是插入到db中的值。表单中的所有其他数据都正确且成功地发布。这个相同的变量没有正确地发布到任何表单上的数据库。我正在查看这篇文章similar issue，因为它是相关的。我不熟悉这些功能，正在读它。
这是我的insert_records php
<?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 (
mrn,
final_hosp_dispo,
date_alt_lvl_care,
actual_discharge_time,

)
VALUES(

}
if (mysqli_query($db_connect, $sql)) {

echo "MRN: $mrn <br />";
echo "Date of Alternate Level of Care Status: $date_alt_lvl_cr_sts <br />";

答案 0 :(得分：1)
SQL关键字不区分大小写（SELECT，FROM，WHERE等），但通常以全部大写形式编写。在某些设置中，表和列名称区分大小写。在你的情况下，MRN应该是mrn。这就是你没有插入数据的原因。
