Posting array from form
提问by Liam
I have a form on my page with a bunch of inputs and some hidden fields, I've been asked to pass this data through a "post array" only im unsure on how to do this,
我的页面上有一个表单，其中包含一堆输入和一些隐藏字段，我被要求通过“post array”传递这些数据，但我不确定如何执行此操作，
Heres a snippet of what im doing at the moment
这是我目前正在做的事情的片段
<form enctype="multipart/form-data" action="process.php" method="POST">
...
more inputs
...
<!-- Hidden data -->
<input type="hidden" name="TimeToRenderHoursInput" value="<?php echo $RenderHours; ?>" />
<input type="hidden" name="TimeToRenderDaysInput" value="<?php echo $RenderDays; ?>" />
<input type="hidden" name="TimeToRenderYearsInput" value="<?php echo $RenderYears; ?>" />
<input type="hidden" name="ContentMinutesInput" value="<?php echo $ContentMinutes; ?>" />
<input type="hidden" name="ContentMinutesSelector" value="<?php echo $ContentMinutesSelector; ?>" />
<input type="hidden" name="PriorityInput" value="<?php echo $Priority; ?>" />
<input type="hidden" name="AvgFrameRenderTimeInput" value="<?php echo $AverageFrameRenderTime; ?>" />
<input type="hidden" name="AvgFrameRenderTimeSelector" value="<?php echo $AverageFrameRenderSelector; ?>" />
<input type="hidden" name="CoresInTestInput" value="<?php echo $CoresInTest; ?>" />
<input type="hidden" name="EstPriceInput" value="<?php echo $EstPrice; ?>" />
<!-- End hidden -->
<input type="image" src="http://www.venndigital.co.uk/testsite/renderbutton/_includes/images/button/submit.jpg" alt="Submit" value="Submit" style="border:0!important;" />
In my process.php im then calling the data as such...
在我的 process.php 中，我然后调用数据...
$first_name = $_POST['first_name'];
$company_name = $_POST['company_name'];
$email_from = $_POST['email'];
$address = $_POST['address'];
$postcode = $_POST['postcode'];
$RenderHours = $_POST['TimeToRenderHoursInput'];
$RenderDays = $_POST['TimeToRenderDaysInput'];
$RenderYears = $_POST['TimeToRenderYearsInput'];
$ContentMinutes = $_POST['ContentMinutesInput'];
$ContentMinutesSelector = $_POST['ContentMinutesSelector'];
$Priority = $_POST['PriorityInput'];
$AverageFrameRenderTime = $_POST['AvgFrameRenderTimeInput'];
$AverageFrameRenderSelector = $_POST['AvgFrameRenderTimeSelector'];
$CoresInTest = $_POST['CoresInTestInput'];
$EstPrice = $_POST['EstPriceInput'];
Is there a way to post it as an array? Is my method bad practice in anyway?
有没有办法将它作为数组发布？无论如何，我的方法是不好的做法吗？

Give each input a name in array format:
以数组格式为每个输入指定一个名称：
<input type="hidden" name="data[EstPriceInput]" value="" />
Then the in PHP $_POST['data'];will be an array:
然后在 PHP$_POST['data'];中将是一个数组：
print_r($_POST); // print out the whole post
print_r($_POST['data']); // print out only the data array

When you post that data, it is stored as an array in $_POST.
当您发布该数据时，它会以数组的形式存储在$_POST.
You could optionally do something like:
您可以选择执行以下操作：
<input name="arrayname[item1]">
<input name="arrayname[item2]">
<input name="arrayname[item3]">
Then:
然后：
$item1 = $_POST['arrayname']['item1'];
$item2 = $_POST['arrayname']['item2'];
$item3 = $_POST['arrayname']['item3'];
But I fail to see the point.
但我没有看到这一点。

You're already doing that, as a matter of fact. When the form is submitted, the data is passed through a post array ($_POST). Your process.php is receiving that array and redistributing its values as individual variables.
事实上，你已经在这样做了。当表单被提交时，数据通过一个post数组（$_POST）传递。您的 process.php 正在接收该数组并将其值重新分配为单个变量。
回答by NJInamdar
Why are you sending it through a post if you already have it on the server (PHP) side?
如果您已经在服务器（PHP）端拥有它，为什么还要通过帖子发送它？
Why not just save the array to the $_SESSIONvariable so you can use it when the form gets submitted, that might make it more "secure" since then the client cannot change the variables by editing the source.
为什么不将数组保存到$_SESSION变量中，以便在提交表单时使用它，这可能会使其更加“安全”，因为客户端无法通过编辑源来更改变量。
It will depend upon how you reallywant to do.
这将取决于您真正想做的事情。
回答by Manunich
You can use the built-in function:
您可以使用内置函数：
extract($_POST);
it will create a variable for each entry in $_POST.
它将为中的每个条目创建一个变量$_POST。

What you are doing is not necessarily bad practice but it does however require an extraordinary amount of typing. I would accomplish what you are trying to do like this.
你所做的不一定是不好的做法，但它确实需要大量的打字。我会像这样完成你想要做的事情。
foreach($_POST as $var => $val){
$$var = $val;
}
This will take all the POST variables and put them in their own individual variables. So if you have a input field named email and the luser puts in [email protected] you will have a var named $email with a value of "[email protected]".
这将获取所有 POST 变量并将它们放入各自的变量中。因此，如果您有一个名为 email 的输入字段，并且 luser 输入了[email protected]，那么您将拥有一个名为 $email 且值为“[email protected]”的变量。

If you want everything in your post to be as $Variables you can use something like this:
如果您希望帖子中的所有内容都作为 $Variables，您可以使用以下内容：
foreach($_POST as $key => $value) {
eval("$" . $key . " = " . $value");
}
foreach($_POST as $key => $value) {
eval("$" . $key . " = " . $value");
}
