如何传递提交php的动态表单的字段名称和值 [英] How to pass field name and value of dynamic form on submit php

问题描述

我有一个表单具有固定的字段以及从数据库创建的动态字段。这些字段可能每次都有所不同，它们是带有颜色大小等选项的下拉列表。我可以这样命名下拉列表：

  name =options []
  

然后执行以下操作：

  foreach（$ options as $ option）{
 //添加到db 
} 
  

然而，只给我一些值，我需要知道optionID以及 b
$ b

可以这样做：

  name =<？echo $ optionID;？> 
  

的下拉菜单，但是当我尝试处理时，我不知道该表单中包含了什么optionID提交的数据。在表单中增加字段时，如何同时传递optionID和选择的值？

解决方案

可以使数组多维。这样的事情可能适用于你：

  name =options [<？php echo $ optionID;？>] [ ]
 
 foreach（$ _POST ['options'] as $ ID）{
 foreach（$ ID as $ value）{
 // stuff 
} 
} 
  

I have a form that has fixed fields as well as dynamic fields created from a database. the fields could be different every time and they are dropdowns with options like color size etc.I could name the dropdowns like this:

name="options[]" 

and then do something like:

foreach($options as $option) {
//add to db
}

however that only gives me the values and I need to know the optionID as well

I could do somethign like:

name="<? echo $optionID; ?>" 

for the dropdown but I don't know what optionID's were included in the form when I try to process the submitted data. how do I pass both the optionID and it's selected value when adding fields to a form dynammically?

解决方案

You can make the array multidimensional. Something like this might work for you:

name="options[<?php echo $optionID;?>][]" 

foreach ($_POST['options'] as $ID) {
  foreach ($ID as $value) {
   // stuff
  }
}
