我正在尝试创建一个优雅的表单处理器,它可以接收POST或GET并循环访问值并显示它们。我想尽可能简单/优雅,并且似乎无法消除GET / POST以支持REQUEST。此代码输出一个额外的值对,我显然不理解GET / POST与REQUEST的关系。当使用POST时,表单包含以前的GET信息(因此它们似乎重叠)并且我不确定如何轻松地不包括cookie(我认为它是什么)值。我知道REQUEST不是最好的方法,但是想知道是否有一种很酷的方式以这种方式使用它。接受其他建议。

<p>
This form should process any combination of inputs... this iteration doesn't handle identically-named inputs other than checkboxes. Would like to figure that out.
</p>
<?php
if ($_GET || $_POST)
//if ($_REQUEST) // why can't I use this?... it seems to process the incoming page as GET on firstload...
{
echo ("<h2>Way to '" . $_SERVER['REQUEST_METHOD'] . "' some! </h2>");
foreach($_REQUEST as $submittedName => $submittedValue)
{
if (is_array($submittedValue)) // for checkboxes with more than one selected value
{
$submittedValue = implode(', ', $submittedValue);
}
echo "For the <b>" . $submittedName . " input, you submitted: :</b> " . $submittedValue."</br>";
}
}
else
{
echo ("<h2>Please submit one of the two forms to see some results.</h2>");
}
?>

GET SOME!
<form action= "" method = "get" >
<input type = "text" name = "name" value = "GIcabad" />
<input type = "text" name = "name2" value = "GIcabad2" />
<input type = "text" name = "name3" value = "GIcabad3" />
<input type = "text" name = "name" value = "GIcabadbb" />
<input type = "text" name = "name2" value = "GIcabad2bb" />
<input type = "text" name = "name3" value = "GIcabad3bb" />
orange:<input type = "checkbox" name = "colors[]" value = "orange" checked />
red:<input type = "checkbox" name = "colors[]" value = "red" />
pink:<input type = "checkbox" name = "colors[]" value = "pink" checked />
<input type = "submit" />
</form>
<br>
POST SOME!
<form action = "" method= "post" >
<input type = "text" name = "name" value = "PIcabad" />
<input type = "text" name = "name2" value = "PIcabad2" />
<input type = "text" name = "name3" value = "PIcabad3" />
<input type = "submit" />
</form>

您可以在应用程序的主文件上循环一次,并将$_GET
和$_POST
存储在单个变量中(它将像$_REQUEST
但是没有{{1} })。然后就可以像这样使用它了
$_COOKIES
修改:表单和结果
<?php
$input_values = array();
$gpcs = array_merge($_POST, $_GET);
foreach ($gpcs as $key => $value) {
$input_values[$key] = $value;
}
// Then you can use anywhere in your application like this
echo isset($input_values['username'])? $input_values['username']:'';
echo isset($input_values['password'])? $input_values['password']:'';
echo isset($input_values['user_type'])? $input_values['user_type']:'';
?>
