Question

我正在尝试使用数组回显表单中的错误。我将错误存储在一个数组中，然后我print_r。但是当我省略某些字段并提交for时，我将字符串“Array”显示为错误。

下面是我正在使用的PHP代码...

<?php
    if (isset($_POST['submit'])) { 
      $error = array();
      if (empty($_POST['request'])) { $error .= "<li>Prayer Request is Empty</li>";}
      if (empty($_POST['phone']))   { $error .= "<li>Please enter a valid phone Number</li>";}
      if (empty($_POST['response'])){ $error .= "<li>Please choose a way to contact you.</li>";}
      ?>
          <div class='Errors' >
          <?php print_r ($error); ?>
          </div>

Answer 1

您对$error = array()的期望是什么？

请尝试$error = "";。

Answer 2

尝试将。=更改为[] =

<?php
  if (isset($_POST['submit'])) { 
  $error = array();
  if (empty($_POST['request'])) { $error[] = "<li>Prayer Request is Empty</li>";}
  if (empty($_POST['phone']))   { $error[] = "<li>Please enter a valid phone Number</li>";}
  if (empty($_POST['response'])){ $error[] = "<li>Please choose a way to contact you.</li>";}
?>
<div class='Errors' >
<?php print_r ($error); ?>
</div>

“数组”在空表单字段中显示为错误
