插入語句和狀態下拉不起作用

你好，我有麻煩讓我的表單驗證正確，以及獲取插入語句發佈確認的消息/張貼到數據庫中的表。插入語句和狀態下拉不起作用

下面是代碼

<?php require_once('dbuser.php');?> 
<?php 
// if the submit button has been selected 
if(isset($_POST['submit_registration'])) { 
    // assign variable to each for control to capture the values

    $email = $_POST['email']; 
    $address1 = $_POST['address1']; 
    $address2 = $_POST['address2']; 
    $city = $_POST['city']; 
    $state = $_POST['state']; 
    $postal = $_POST['postal_code']; 
    $phone = $_POST['phone']; 
    $distance = $_POST['dist']; 
    //assign null values for use with the isset function to identify null fields that are missing a value 
    $nofirst = null; 
    $nolast = null;

您不需要像這樣在所有選項標籤中分配名稱。 <option value="AL" name="AL" title="alabama">Alabama</option> 在<select name="dropdownname">只需指定一個名稱，並把它在你的要求$city = $_POST['dropdownname'];

我剛剛編輯你的PHP代碼，因爲當我在這拍了一下我看到了很多的if語句。這並不能解決你的問題，但它使你的代碼更具可讀性。

保存時應該避開變量。

您是否轉過錯誤報告？

希望我的代碼能幫助你一點點。對於輸入字段，可以使用下例所示的相同變量。在你輸入字段的值，你可以使用代碼：

<input name="first_name" value="<?php echo isset($first_name) ? $first_name : '' ?>">

這是因爲如果別人短。如果設置了first_name，那麼echo $ first_name或者echo'';

<?php require_once('dbuser.php');?> 
<?php 
error_reporting(E_ALL); 
ini_set("display_errors", 1); 


// if the submit button has been selected 
if(isset($_POST['submit_registration'])) { 
    //Those are the predefined fields, set in a array 
    $fieldsArray = ['first_name', 'last_name', 'email', 'address1', 'address2', 'city', 'state', 'postal_code', 'phone', 'dist']; 

    //The fields are always valid unless we get something else while looping 
    $valid = true; 
    //Loop through the fieldsArray 
    foreach($fieldsArray as $key => $value){ 
     if(isset($_POST[$value])){ 
      //If $_POST with the value from the fieldsArray is SET, then create a variable called $first_name or $last_name, depends on the keys from 
      // the fields array 
      ${$value} = $_POST[$value]; 
     } else { 
      //If the value is not set, then the validation is false 
      $valid = false; 
     } 
    } 

    //If false, then dont run the query 
    if($valid == false) 
    { 
     $confim = 'Please enter all values'; 
    } else { 
     $insertsql = "INSERT INTO `runner`(`fname`, `lname`,`email`,`address1`,`address2`,`city`,`state`,`postalcode`, `phone`, `distance`) VALUES ('".$first."', '".$last_name."', '$email', '$address1','$address2','$city','$state','$postal','$phone','$distance')"; 
     mysqli_query($lrconnect, $insertsql) or die ("Insert failed: ".mysql_error($lrconnect)); 
     $confirm = 'Thank you for registering!'; 
    } 
}
