Get all variables sent with POST?
提问by lisovaccaro
I need to insert all variables sent with post, they were checkboxes each representing an user.

如果我使用 GET 我得到这样的东西:
?19=on&25=on&30=on
I need to insert the variables in the database.
我需要在数据库中插入变量。
How do I get all variables sent with POST? As an array or values separated with comas or something?

The variable $_POST
is automatically populated.
该变量$_POST
会自动填充。
Try var_dump($_POST);
to see the contents.
尝试var_dump($_POST);
查看内容。
You can access individual values like this: echo $_POST["name"];
您可以像这样访问单个值: echo $_POST["name"];
This, of course, assumes your form is using the typical form encoding (i.e. enctype=”multipart/form-data”
当然,这假设您的表单使用典型的表单编码(即 enctype=”multipart/form-data”
If your post data is in another format (e.g. JSON or XML, you can do something like this:
如果您的帖子数据采用另一种格式(例如 JSON 或 XML,您可以执行以下操作:
$post = file_get_contents('php://input');
and $post
will contain the raw data.
并且$post
将包含原始数据。
Assuming you're using the standard $_POST
variable, you can test if a checkbox is checked like this:
假设您使用的是标准$_POST
变量,您可以测试复选框是否被选中,如下所示:
if(isset($_POST['myCheckbox']) && $_POST['myCheckbox'] == 'Yes')
{
...
}
If you have an array of checkboxes (e.g.
如果您有一组复选框(例如
<form action="myscript.php" method="post">
<input type="checkbox" name="myCheckbox[]" value="A" />val1<br />
<input type="checkbox" name="myCheckbox[]" value="B" />val2<br />
<input type="checkbox" name="myCheckbox[]" value="C" />val3<br />
<input type="checkbox" name="myCheckbox[]" value="D" />val4<br />
<input type="checkbox" name="myCheckbox[]" value="E" />val5
<input type="submit" name="Submit" value="Submit" />
</form>
Using [ ]
in the checkbox name indicates that the selected values will be accessed by PHP script as an array. In this case $_POST['myCheckbox']
won't return a single string but will return an array consisting of all the values of the checkboxes that were checked.
使用[ ]
在复选框名称表示所选择的值将通过PHP脚本作为阵列进行访问。在这种情况下,$_POST['myCheckbox']
不会返回单个字符串,而是返回一个数组,该数组由选中的复选框的所有值组成。
For instance, if I checked all the boxes, $_POST['myCheckbox']
would be an array consisting of: {A, B, C, D, E}
. Here's an example of how to retrieve the array of values and display them:
例如,如果我选中所有框,$_POST['myCheckbox']
将是一个包含以下内容的数组:{A, B, C, D, E}
。以下是如何检索值数组并显示它们的示例:
$myboxes = $_POST['myCheckbox'];
if(empty($myboxes))
{
echo("You didn't select any boxes.");
}
else
{
$i = count($myboxes);
echo("You selected $i box(es): <br>");
for($j = 0; $j < $i; $j++)
{
echo $myboxes[$j] . "<br>";
}
}

you should be able to access them from $_POST
variable:
您应该能够从$_POST
变量访问它们:
foreach ($_POST as $param_name => $param_val) {
echo "Param: $param_name; Value: $param_val<br />\n";
}

It is deprecated and not wished to access superglobals directly (since php 5.5 i think?)
它已被弃用,并且不希望直接访问超全局变量(我认为是 php 5.5 起?)
Every modern IDE will tell you:
每个现代 IDE 都会告诉您:
Do not Access Superglobals directly. Use some filter functions (e.g.
filter_input
)
不要直接访问超全局变量。使用一些过滤功能(例如
filter_input
)
For our solution, to get all request parameter, we have to use the method filter_input_array
对于我们的解决方案,要获取所有请求参数,我们必须使用该方法 filter_input_array
To get all params from a input method use this:
要从输入法中获取所有参数,请使用以下命令:
$myGetArgs = filter_input_array(INPUT_GET);
$myPostArgs = filter_input_array(INPUT_POST);
$myServerArgs = filter_input_array(INPUT_SERVER);
$myCookieArgs = filter_input_array(INPUT_COOKIE);
...
Now you can use it in var_dump
or your foreach
-Loops
现在你可以在var_dump
你的foreach
-Loops 中使用它
What not works is to access the $_REQUEST Superglobal with this method. It Allways returns NULL
and that is correct.
不起作用的是使用此方法访问 $_REQUEST Superglobal。它总是返回NULL
,这是正确的。
If you need to get all Input params, comming over different methods, just merge them like in the following method:
如果您需要获取所有输入参数,通过不同的方法,只需像以下方法一样合并它们:
function askForPostAndGetParams(){
return array_merge (
filter_input_array(INPUT_POST),
filter_input_array(INPUT_GET)
);
}
Edit: extended Version of this method (works also when one of the request methods are not set):
编辑:此方法的扩展版本(在未设置其中一种请求方法时也有效):
function askForRequestedArguments(){
$getArray = ($tmp = filter_input_array(INPUT_GET)) ? $tmp : Array();
$postArray = ($tmp = filter_input_array(INPUT_POST)) ? $tmp : Array();
$allRequests = array_merge($getArray, $postArray);
return $allRequests;
}
