我有以下五个带有类似
name=check[]
复选框的代码
<input type='checkbox' value='1' name='check[]'/>
<input type='checkbox' value='1' name='check[]'/>
<input type='checkbox' value='1' name='check[]'/>
<input type='checkbox' value='1' name='check[]'/>
<input type='checkbox' value='1' name='check[]'/>
I am sending this data to PHP page using form and extracting this data in php as following 我使用表单将数据发送到PHP页面,并按照以下步骤在php中提取数据
<?php
$check=$_POST['check'];
print_r($check);
?>
Output for three checked checkboxes will always be as following even If i check checkbox no 1,2,5 or 1,3,4 即使我未选中1,2,5或1,3,4复选框,三个已选中复选框的输出也始终如下
Array
(
[0] => 1
[1] => 1
[2] => 1
)
For Example: 例如:
If there are total five checkboxes and i only checked 1st and 3rd checkbox then my output must be 如果总共有五个复选框,而我只选中了第一和第三复选框,那么我的输出必须是
Array
(
[1] => 1
[3] => 1
)
or 要么
Array
(
[1] => 1
[2] => 0
[3] => 1
[4] => 0
[5] => 0
)
The browser will send the values of the checked checkboxes, right now your values are always 1. 浏览器将发送选中的复选框的值,现在您的值始终为1。
Try changing your code to: 尝试将代码更改为:
<input type='checkbox' value='1' name='check[]'/>
<input type='checkbox' value='2' name='check[]'/>
<input type='checkbox' value='3' name='check[]'/>
<input type='checkbox' value='4' name='check[]'/>
<input type='checkbox' value='5' name='check[]'/>
get all the values from the checkboxes like you are doing, than do a for loop untill the length of array and if particular value of any key is 1 than you can do process on it as you like for example 像执行操作一样从复选框中获取所有值,然后执行for循环直到数组的长度,并且如果任何键的特定值是1,那么您就可以根据需要对其进行处理,例如
$data = array(
[1] => 1
[2] => 0
[3] => 1
[4] => 0
[5] => 0
);
$output=array();
for($i=1; $i<=count($data); $i++)
{
if($data[$i])== 1)
$output[] = $data[$i];
}
print_r($output);
i hope this will solve your problem. 我希望这能解决您的问题。
