用post发送和打印数组值

Question

为什么我的ECHO不打印值1？

<dl><input type='checkbox' class='tinyField' name="informTktUpdate['hd']" value="1" /> Inform user by email</dl>
<dl><input type='checkbox' class='tinyField' name="informTktUpdate['prog']" value="1"  /> Inform programmer by email</dl>

echo ($_POST['informTktUpdate']['prog']);

如果我正在使用“print_r（（$ _ POST ['informTktUpdate']）”我得到：

 Array ( ['hd'] => 1 ['prog'] => 1 ) 

Answer 1

删除HTML部分中数组键周围的引号。 它必须是

<input type='checkbox' class='tinyField' name="informTktUpdate[hd]" value="1" />
