< input type="checkbox" name="weeks[]"  id="weeks" value=1>   < input type="checkbox" name="weeks[]"  id="weeks" value=2>   < input type="checkbox" name="weeks[]"  id="weeks" value=3> 

weeks后的中括号不可漏,否则用PHP获取的时候只能取到最后一个值。之后PHP就很好处理了,如下:

方法一:

$weeks = $_POST['weeks'];   for($i=0;$i< count($weeks);$i++)       echo $weeks[$i]."< br>"; 

 

方法二:

$array = $this->request->getParameter("weeks[]");   $str =implode(',',$array);   echo $str; 

 

经常用到表单,其中复选框要经常用。但在PHP中与其他的脚本语言不太一样,复选框的名称后面必须加上[],然后用数组循环取得。

< ?PHP      if(!empty($_POST["t1"])){              $array = $_POST["t1"];              $size = count($array);              for($i=0; $i< $size; $i++){                    echo $array[$i]."< br>";              }      }  ?>     < form method=post action="" name="form1">     < input type="checkbox"  name="t1[]" value="篮球">篮球< br>     < input type="checkbox"  name="t1[]" value="足球">足球< br>     < input type="checkbox"  name="t1[]" value="乒乓球">乒乓球< br>     < input type="checkbox"  name="t1[]" value="排球">排球< br>     < input type="submit">     < /form>
