发送多个复选框选项 [英] Sending multiple checkbox options

问题描述

我正在创建一个二手车网站（用PHP编写），并且我坚持从表单发送高级搜索选项。我有超过30个，我想知道是否有可能以及如何将它们发送到一个变量中（例如& options = 1,2,3,5,6,10 或其他方式..）。

另外我听说这是可能的按位，但我没有线索如何去做。或者如果有人有更好的主意，请让我知道。

谢谢。 您可以将它们发送到数组中。

 < form method =post> 
< input type =checkboxname =param []value =blue/> 
< input type =checkboxname =param []value =red/> 
< input type =checkboxname =param []value =orange/> 
< input type =checkboxname =param []value =green/> 
< input type =checkboxname =param []value =black/> 
< input type =submitvalue =Submit/> 
< / form> 
 
>> $ _POST ['param'] 
 array（'blue'，'orange'）
  

您甚至可以使用多维数组：

 < form method =post> 
< input type =checkboxname =param [color] []value =blue/> 
< input type =checkboxname =param [color] []value =red/> 
< input type =checkboxname =param [color] []value =orange/> 
< input type =checkboxname =param [color] []value =green/> 
< input type =checkboxname =param [color] []value =black/> 
< input type =checkboxname =param [year] []value =1999/> 
< input type =checkboxname =param [year] []value =2000/> 
< input type =checkboxname =param [year] []value =2001/> 
< input type =checkboxname =param [year] []value =2002/> 
< input type =checkboxname =param [year] []value =2003/> 
< input type =submitvalue =Submit/> 
< / form> 
 
>> $ _POST ['param'] ['color'] 
 array（'blue'，'green'）
 
>> $ _POST ['param'] ['year'] 
 array（'2001'，'2004'）
  

I'm creating a used cars website (written in PHP), and I'm stuck on sending advanced search options from form. I have more than 30 of them and I wonder if it's possible, and how, to send them in one variable (for example &options=1,2,3,5,6,10 or some other way..).

Also I've heard that this is possible with "bitwise" but I don't have a clue how to do that. Or if someone have a better idea, please let me know.

Thanks.

解决方案

You can send them in an array.

<form method="post">
    <input type="checkbox" name="param[]" value="blue" />
    <input type="checkbox" name="param[]" value="red" />
    <input type="checkbox" name="param[]" value="orange" />
    <input type="checkbox" name="param[]" value="green" />
    <input type="checkbox" name="param[]" value="black" />
    <input type="submit" value="Submit" />
</form>

>> $_POST['param']
array('blue', 'orange')

You can even use multidimensional arrays:

<form method="post">
    <input type="checkbox" name="param[color][]" value="blue" />
    <input type="checkbox" name="param[color][]" value="red" />
    <input type="checkbox" name="param[color][]" value="orange" />
    <input type="checkbox" name="param[color][]" value="green" />
    <input type="checkbox" name="param[color][]" value="black" />
    <input type="checkbox" name="param[year][]" value="1999" />
    <input type="checkbox" name="param[year][]" value="2000" />
    <input type="checkbox" name="param[year][]" value="2001" />
    <input type="checkbox" name="param[year][]" value="2002" />
    <input type="checkbox" name="param[year][]" value="2003" />
    <input type="submit" value="Submit" />
</form>

>> $_POST['param']['color']
array('blue', 'green')

>> $_POST['param']['year']
array('2001', '2004')
