如何将PHP中复选框的多个数组值传递到另一个页面？

Question

我想创建一个选择页面（通过使用复选框），最后它将显示选择所有复选框的结果。在我的第一页（仅包含 HTML）中有大约 5 种不同类别的复选框，分别用于情感、时间、动作、工具和个性化。

首页：index.php

<?php
$emotions = (isset($_POST['emotions'])) ? $_POST['emotions'] : array(); ?>
<p><strong>Emotions :</strong>
    <?php
    if (count($emotions) > 0) {
        foreach ($emotions as $emotions) {
            echo $emotions . ' ';
        }
    } else {
        echo "No emotions has been selected";
    }
    ?>
</p> 

<?

        }
    } else {
        echo "No tools has been selected";

    ?>
</p>

        }

        echo "No personalization has been selected";

Answer 1

查看您的 foreach。 你要做的是：

$array = [1, 2, 3];
foreach($array as $array){
  // $array is no more an array, but have the first value of the init array : 1
}

就像你这样做：$array = $array[0]

你必须做类似的事情：

$array = [1, 2, 3];
foreach($array as $ar){
  ...
  // code for $ar
  ...
}

Answer 2

检查您是否在表单标签的action属性中输入了正确的路径以到达“process.php”文件
