$_POST Array from html form
提问by James Stafford
I am trying to send data from multiple checkboxes (id[]) and create an array "info" in php to allow me to run a script for each value (however the quantity of values may change each time) however first I am trying to display the content of each array value. I am not quite sure how to put my array populating line to save all the content to the array.
我正在尝试从多个复选框（id []）发送数据并在 php 中创建一个数组“信息”以允许我为每个值运行一个脚本（但是每次值的数量可能会改变）但是首先我试图显示每个数组值的内容。我不太确定如何放置我的数组填充行以将所有内容保存到数组中。

echo("<input name='id[]' type='checkbox' value='".$shopnumb."'>");
my hopeful processing code currently is -
我目前希望的处理代码是 -
$info=$_POST['id[]'];
Echo(array_values($info));
what do I need to do to make the content sent by post from the form checkboxes populate the array info
我需要做什么才能使表单复选框中的 post 发送的内容填充数组信息
any help is greatly appreciated

Change
改变
$info=$_POST['id[]'];
to
到
$info=$_POST['id'];
by adding []to the end of your form field names, PHP will automatically convert these variables into arrays.
通过添加[]到表单字段名称的末尾，PHP 会自动将这些变量转换为数组。

You should get the array like in $_POST['id']. So you should be able to do this:
你应该像 $_POST['id'] 那样得到数组。所以你应该能够做到这一点：
foreach ($_POST['id'] as $key => $value) {
echo $value . "<br />";
}
Input names should be same:
输入名称应该相同：
<input name='id[]' type='checkbox' value='1'>
<input name='id[]' type='checkbox' value='2'>
...

<input name='id[]' type='checkbox' value='".$shopnumb."\'>
<input name='id[]' type='checkbox' value='".$shopnumb."\'>
<input name='id[]' type='checkbox' value='".$shopnumb."\'>
$id = implode(',',$_POST['id']);
echo $id
you cannot echo an array because it will just print out Array. If you wanna print out an array use print_r.
您不能回显数组，因为它只会打印出数组。如果你想打印出一个数组，请使用print_r.
print_r($_POST['id']);

I don't know if I understand your question, but maybe:
我不知道我是否理解你的问题，但也许：
foreach ($_POST as $id=>$value)
if (strncmp($id,'id[',3) $info[rtrim(ltrim($id,'id['),']')]=$_POST[$id];
would help

That is if you really want to have a different name (id[key]) on each checkbox of the html form (not very efficient). If not you can just name them all the same, i.e. 'id' and iterate on the (selected) values of the array, like: foreach ($_POST['id'] as $key=>$value)...
也就是说，如果您真的想在 html 表单的每个复选框上使用不同的名称 (id[key])（效率不高）。如果不是，您可以将它们全部命名为相同，即 'id' 并迭代数组的（选定的）值，例如：foreach ($_POST['id'] as $key=>$value)...
