Question

thinkphp取不到checkbox的值

<input type="checkbox" name="week[]" id="week1" value="1" />周一
<input type="checkbox" name="week[]" id="week2" value="2" />周二
<input type="checkbox" name="week[]" id="week3" value="3" />周三
<input type="checkbox" name="week[]" id="week4" value="4" />周四
<input type="checkbox" name="week[]" id="week5" value="5" />周五
<input type="checkbox" name="week[]" id="week6" value="6" />周六
<input type="checkbox" name="week[]" id="week0" value="0" />周日

获取值：

$week = $_POST ['week'];
var_dump($week);

获取到的不是选中的值，而是字符串"Array"
是哪里错了吗？

Answer 1

<?php
    if(isset($_POST['week'])){
        var_dump($_POST['week']);
    }
?>

<form action="" method="post">
<input type="checkbox" name="week[]" id="week1" value="1" />周一
<input type="checkbox" name="week[]" id="week2" value="2"  />周二
<input type="checkbox" name="week[]" id="week3" value="3"  />周三
<input type="checkbox" name="week[]" id="week4" value="4"  />周四
<input type="checkbox" name="week[]" id="week5" value="5"  />周五
<input type="checkbox" name="week[]" id="week6" value="6"  />周六
<input type="checkbox" name="week[]" id="week0" value="0" />周日   
<input type="submit" value="提交" />
</form>

没什么问题

Answer 2

没错，传过来的就是个数组，你可以使用print_r($week);
