Question

我有一个相对简单的PHP表单。当我使用print_r($_POST);时，我什么也没收到。只是这个结果：

`Array
  (
  )
  1`

我的表单非常简单：

<form action="" method="post" enctype="multipart/form-data" class="zip-<?php echo $atts['class']; ?>">
        <div class="row ">
            <div class="<?php echo $column1; ?>" <?php echo $inlineStyle ?>>
                <div class="lds-facebook hide"><div></div><div></div><div></div><div></div><div></div></div>
                <input type="text" name="zip" class="zip">
            </div>
            <div class="<?php echo $column2 ?>">
                <button type="submit" class="submit" name="submit">
                  <?php echo $buttonValue; ?>
                  <i class='fa fa-caret-right' aria-hidden='true'></i>
                </button>
            </div>
        </div>
    </form>

表单的目标是简单地发布，然后根据从输入接收的值重定向到页面。有什么想法吗？

public static function find_zip_widget( $atts, $content = null ) { 
    ini_set('display_errors', '1');

    extract(shortcode_atts(array(
    'class' => 'class'
), $atts));

    // Set classes for rows
    if($atts['class'] == 'home'){
        $column1 = 'col-md-6 col-12 my-auto text-center border-underline';
        $column2 = 'col-md-6 col-12';
        $buttonValue = 'FIND HELP RIGHT NOW';
        $inlineStyle = '';
    }

    if($atts['class'] == 'widget'){
        $column1 = 'col-md-5 col-5 offset-2 offset-md-0 my-auto';
        $column2 = 'col-md-7 col-5 my-auto';
        $buttonValue = 'SUBMIT';
        $inlineStyle = 'style="border-bottom: 3px solid #9EA2A4 !important;min-height: 30px;"';
    }

    ?>
    <form action="" method="post" enctype="multipart/form-data" class="zip-<?php echo $atts['class']; ?>">
        <div class="row ">
            <div class="<?php echo $column1; ?>" <?php echo $inlineStyle ?>>
                <div class="lds-facebook hide"><div></div><div></div><div></div><div></div><div></div></div>
                <input type="text" name="zip" class="zip">
            </div>
            <div class="<?php echo $column2 ?>">
                <button type="submit" class="submit" name="submit">
                  <?php echo $buttonValue; ?>
                  <i class='fa fa-caret-right' aria-hidden='true'></i>
                </button>
            </div>
        </div>
    </form>

    <?php    
        echo "<pre>";
        echo "Before if: ";
        echo  print_r($_POST);

        'taxonomy' => 'endeavors_location_state'
        ) );


        if (isset($_POST['submit'])) {
            $postalZip = $_POST["zip"];

            echo "<pre>";
            echo "After if: ";
            echo  print_r($_POST);

Answer 1

您的脚本发布到服务器很好，但是在到达print_r（$ _ POST）之前，它已重定向到相同的位置。因此未执行print_r（$ _ POST）。请参考下图以获取更多信息。有两个请求，一个是具有302重定向的帖子。我怀疑可能涉及到JavaScript重定向。

Answer 2

我刚刚运行了您的脚本（xampp，php 7.1.26，mac Mojave），它会打印

Array ( [zip] => testvalue [submit] => )

我在标签的顶部添加了<?php print_r($_POST); ?>。（您可能也做过同样的事情）对我来说，它按预期运行。

很傻，但是只是想知道您是否提交了表格？如果没有，它将显示一个空数组

我的PHP表单未从$ _POST返回任何内容
