Question

我有单独的电子邮件脚本;但是，如果没有错误，我们将如何运行该代码。我有一个表单错误$errors = array($nameErr, $emailErr, $phoneErr, $zipErr, $serviceErr);的数组，但它们有不同的字符串，如果数组中没有字符串或Null或''，我们希望发送电子邮件。

<?php
// define variables and set to empty values

   if (empty($_POST["name"])) {
     $nameErr = "name required.";
   } else {

     // check if name only contains letters and whitespace
     if (!preg_match("/^[a-zA-Z ]*$/",$name)) {

Answer 1

尝试使用以下代码：

$errors = array($nameErr, $emailErr, $phoneErr, $zipErr, $serviceErr);  
if (isset($_POST['Submit'])) {
   if(!array_filter($errors)){
           // code here 
   }
   else {
   echo "Error";
   }
}

将错误保存在数组中，然后检查数组末尾是否为空。如果是这样，没有错误 - 提交电子邮件。否则，显示错误：

//dont declare separate variables,use an array
//$nameErr = $phoneErr = $emailErr = $zipErr = $serviceErr = "";
$errors = [];

if (empty($_POST["name"])) {
     $errors['nameErr'] = "name required.";
   } else {
     $name = test_input($_POST["name"]);
     // check if name only contains letters and whitespace
     if (!preg_match("/^[a-zA-Z ]*$/",$name)) {
       $errors['nameErr'] = "letters and spaces only."; 
     }
   }

//other validation here, then

if(empty($errors){
    //no errors, submit
    your_submit_function();
}else{
    //display errors
    foreach($errors as $val){
        echo $val . '<br/>';
    }
}

PHP如果没有错误，如何提交表单。没有javascript
