cakephp:如何从Web窗体中获取元素数组 [英] cakephp : how to get an array of elements from a web form
问题描述
在我的cakephp表单中,我有以下代码
In my cakephp form I have following code
<p> <?php echo $form->input('option[]',array('size'=>13)); ?> </p>
<p> <?php echo $form->input('option[]',array('size'=>13)); ?> </p>
<p> <?php echo $form->input('option[]',array('size'=>13)); ?> </p>
<p> <?php echo $form->input('option[]',array('size'=>13)); ?> </p>
我试图从一组输入文本框中获取值,文本框的数量可以是由用户设置,所以不能给每个文本框的个别名称,但如何从我的控制器获取值插入数据到db表
I am trying to get values from a set of input text boxes, the number of text boxes can be set by the user, so cant give individual names of each text box, but How can I get values from my controller to insert data to db table
谢谢
推荐答案
您可以保留表单,并使用@Wizzard和@Lee的建议,但最好的做法是使用递增变量以构造列表。即:
You can leave the form as it is (and use suggestions from @Wizzard and @Lee), but the best practice is to use an incrementing variable to construct the list. i.e.:
for($i=0;$i<$option_number;$i++){
echo $form->input("MyModel.{$i}.option");
}
这样,发布表单后的变量将如下所示:
This way your variable after posting the form will look like:
data [MyModel] [0] [option] ='值'
data MyModel [option] ='值'
data [MyModel] [2] [option] ='值'
.. ...等等...
data[MyModel][0][option] = 'the value' dataMyModel[option] = 'the value' data[MyModel][2][option] = 'the value' ... and so on...
在控制器中,您可以通过以下方式访问发布的数据:
In the controller you can access the posted data by:
print_r $ this-> data);
print_r($this->data);
查看 saveAll()(在浏览器中搜索saveAll并查找建议的数据结构)
Take a look saveAll() (search for saveAll in your browser and look for suggested data structure)
