PHP遍历HTML文本框的数组 [英] PHP loop through array of HTML textboxes

问题描述

我有一个复选框领域，所有这些都封装在提交表单中的一些动态的HTML表单。当提交表单时，我想通过每个复选框字段的值与循环PHP脚本。与此同时，我必须保持与复选框字段相关的某个ID，这样，当我通过每一个在我的脚本循环，我可以使用该ID在我的数据库更新正确的行。目前，我有：

I have an HTML form with a dynamic number of checkbox fields, all of which are encapsulated within a submit form. When the form is submitted, I want to loop through the values of each checkbox field with a PHP script. At the same time, I have to keep a certain ID associated with the checkbox field so that when I loop through each one in my script, I can use the ID to update the correct row in my database. Currently, I have:

<input checked="checked" name="attended_<?php echo($pid); ?>"

我只是不知道如何继续和访问所有参加[]值从我的PHP脚本（并保持ID在同一时间）。我会用一个多维数组像下面这样？

I'm just not sure how to go ahead and access all of the attended[] values from my PHP script (and keep the ID at the same time). Would I use a multidimensional array like the following?

<input checked="checked" name="attended[<?php echo($i); ?>][<?php echo($pid); ?>]; ?>"

我倒是AP preciate有这方面的帮助。谢谢！

I'd appreciate any help on this. Thanks!

推荐答案

通常当我创建复选框，我把一个索引的名字。这样，您就可以遍历您submittion code分别复选框。

Usually when I create checkboxes I put an index in the name. This way you can loop through each checkbox in your submittion code.

<input type="checkbox" name="cbGroup[1]" value="y" />
<input type="checkbox" name="cbGroup[2]" value="y" />
<input type="checkbox" name="cbGroup[3]" value="y" />

和你的PHP

foreach($_POST['cbGroup'] as $index=>$checkbox) {}

您会想要确保你的$ _ POST ['cbGroup']设置虽然，因为如果没有选中该复选框也不会是。

You'll want to make sure your $_POST['cbGroup'] is set though because it won't be if the checkbox isn't checked.

编辑：对不起，我应该学会阅读问题完全嘿嘿:)我用多维数组在PHP与HTML的输入所有的时间，我认为这是我要走的路。

Sorry, I should learn to read the question fully heh :) I use multidimensional arrays in PHP with HTML inputs all the time and I think it's the way I would go.
