PHP验证未在特定位置运行

Question

    <?php
include 'header.inc.php ';

<?php

<?php

      //echo $nameError;
  }
  $password1=($_POST["password1"]);
  if(mb_strlen($password1) <8 || preg_match('/[^0-9A-Za-z]/', $password1)) // [^] sign means complement of all those number and alpha, so if password match with something not alpha or number enter the if condition
    {
          $passwordError1= "<span style='color: red';> ONLY CAN USE ALPHABETS OR NUMBERS AND MINIMUM LENGTH Of 8 CHARACTERS </span>";
    }
  $password2=($_POST["password2"]);
  if ($password2 !== $password1)
  {
      $passwordError2="<span style='color: red';> Mismatching passwords! </span>";

<?php
include 'footer.inc.php ';
?>

此处附加的代码按原样运行良好，但是当我尝试移动PHP验证代码时，主要是从is_set（$ _ post [submit]）移至HTML文档底部的页脚php文件所在的区域上方包括验证不再运行。 请向我解释为什么会这样吗？

我不知道这是否是您的意思。 ..在您的情况下，我会将所有错误堆叠在一起，如果有任何错误停止，请执行其他操作：

$erors='';

if(isset($_POST['submit'])){

    $firstName = ($_POST["firstname"]);
    if (empty($firstName)){
      $erors .= "<span style='color: red';> Name is required </span>";
    }

    $lastName = ($_POST["lastname"]);
    if (empty($lastName)){
        $erors . = "<span style='color: red';> Last Name is required </span>";
    }

    $email = ($_POST["email"]);
    if (!filter_var($email, FILTER_VALIDATE_EMAIL)){
        $erors . = "<span style='color: red';> Proper Email account is required </span>";
    }

    $password1=($_POST["password1"]);
    if(mb_strlen($password1) <8 || preg_match('/[^0-9A-Za-z]/', $password1)){
        $erors .= "<span style='color: red';> ONLY CAN USE ALPHABETS OR NUMBERS AND MINIMUM LENGTH Of 8 CHARACTERS </span>";
    }

    $password2=($_POST["password2"]);
    if ($password2 !== $password1){
        $erors .="<span style='color: red';> Mismatching passwords! </span>";
    }

    if($erors){
        echo $erors;
    } else{
        //do stuff
    }
}
