您好我无法让我的表单验证正确以及获取insert语句以将确认的消息/帖子发布到数据库中的表。
这是代码
<?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
$first = $_POST['first_name'];
$last = $_POST['last_name'];
$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;
$noemail = null;
$noaddress1 = null;
$noaddress2 = '';
$nocity = null;
$nostate= null;
$nopostal = null;
$nophone = null;
$nodistance = null;
// if value of variable is nothing assign something other than null
if($first=="") {
$nofirst = '';
$novalue = '';
}
if($last==""){
$nolast = '';
$novalue ='';
}
if($email=="") {
$noemail = '';
$novalue = '';
}
if($address1=="") {
$noaddress1 = '';
$novalue = '';
}
if($address2=="") {
$noaddress2 = '';
$novalue = '';
}
if($city=="") {
$nocity = '';
$novalue = '';
}
if($state=="") {
$nostate = '';
$novalue = '';
}
if($postal=="") {
$nopostal = '';
$novalue = '';
}
if($phone=="") {
$nophone = '';
$novalue = '';
}
if($distance=="") {
$nodistance = '';
$novalue = '';
}
if(isset($novalue)) {$confim = 'Please enter all values';}
else {
$insertsql = "INSERT INTO `runner`(`fname`, `lname`,`email`,`address1`,`address2`,`city`,`state`,`postalcode`, `phone`, `distance`) VALUES ('$first', '$last', '$email', '$address1','$address2','$city','$state','$postal','$phone','$distance')";
mysqli_query($lrconnect, $insertsql) or die ("Insert failed: ".mysql_error($lrconnect));
$confirm = 'Thank you for registering!';
}
}

非常感谢任何帮助！

您不需要像这样在所有选项标签中分配名称。
<option value="AL" name="AL" title="alabama">Alabama</option>
只需在<select name="dropdownname">中指定一个名称，然后在请求$city = $_POST['dropdownname'];

我刚编辑了你的PHP代码，因为当我看一下它时，我看到了很多if语句。这并不能解决您的问题，但它会使您的代码更具可读性。
保存时应该转义变量。
您是否启用了错误报告？
希望我的代码可以为您提供一些帮助。对于输入字段，您可以使用示例中显示的相同变量。在输入字段值中，您可以使用代码：
<input name="first_name" value="<?php echo isset($first_name) ? $first_name : '' ?>">
如果不这样做，则会更短。如果设置了first_name，则echo $ first_name或者echo＆＃39;＆＃39;;
<?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!';
}
}
