HTML Mutli选择不发布值返回到PHP [英] HTML Mutli Select Not Posting Values Back to PHP

问题描述

 < select multiple = 
我有一个html格式的选择框， 'multiple'name ='mydropdown'> 
< option value ='1'> 1< / option> 
< option value ='2'> 2< / option> 
< option value ='3'> 3< / option> 
< / select> 
  

在PHP中，如果我看看 $ _ REQUEST 它会在选择框中为最后选定的值返回单个值。

为了获得数组或列表，需要更改或编辑什么？选择的项目发回来，以便我可以在PHP中处理结果？

我想将select转换为 JQuery multi select box，所以如果你的答案可以应用于JQuery选择框并且我将不胜感激。PHP解决方案

PHP需要表单控件名称以 [] 结尾，如果您从相同名称获得多个值。

 < select multiple ='multiple'name ='mydropdown []'> 
  

获取多个值的原因是多个表单控件具有相同的名称，或者单个选择多个元素。

I have a select box in a html form that does not post values back to php.

<select multiple='multiple' name='mydropdown'>
    <option value='1'>1</option>
    <option value='2'>2</option>
    <option value='3'>3</option>
</select>

in PHP if I have a look at the $_REQUEST it returns a single value for the LAST selected value in the select box.

What do I need to change or edit in order to get a array or list of selected items posted back so that I can handle the result in PHP?

I would like to transform the select into a JQuery multi select box so if your answer could apply to JQuery select boxes aswell I would appreciate it

解决方案

PHP requires that form control names end in [] if you are getting multiple values from the same name.

<select multiple='multiple' name='mydropdown[]'>

It doesn't matter if the reason for getting multiple values is multiple form controls with the same name, or a single select multiple element.
