Question

因此，我需要为比赛创建一个包含个人数据和图像的表单。我正在运行它，但是我需要一个相同的提交按钮来检测上载的文件和输入数据中的错误。

现在，它仅查找上传文件中的错误

我尝试为输入错误添加一个数组，并将其添加到$ fileError === 0 if语句中，但它显示错误

<?php

$firstnameErr = $surnameErr = $address1Err = $emailErr = $phoneErr = $instaErr = $GDPRErr= "";
$ResultERRORS = array("firstnameErr", "surnameErr", "address1Err", "emailErr", "phoneErr", "instaErr", "GDPRErr");
$firstname = $surname = $address1 = $address2 = $email = $phone = $insta = $GDPR = "";

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

  if (empty($_POST["firstname"])) {
    $firstnameErr = "Firstname is required";
  } else {
    $firstname = test_input($_POST["firstname"]);
    // check if name only contains letters and whitespace
    if (!preg_match("/^[a-zA-Z ]*$/",$firstname)) {
      $firstnameErr = "Only letters and white space allowed";
    }
  }

  if (empty($_POST["surname"])) {
    $surnameErr = "Surname is required";
  } else {
    $surname = test_input($_POST["surname"]);

    if (!preg_match("/^[a-zA-Z ]*$/",$surname)) {
      $surnameErr = "Only letters and white space allowed";

  $allowed = array('jpg', 'jpeg', 'png', 'pdf');

  if (in_array($fileActualExt, $allowed)) {

function test_input($data) {

?>

<div id="forms">

  </form>
</div>

<span class="upload_error"><?php if(isset($message)){echo $message;} ?></span>

我希望上传按钮同时检测$ fileErrors和$ ResultERRORS数组

PHP问题：具有“提交”按钮可检测HTML表单和文件上传中的错误
