这是家庭作业,我们需要使用PHP。除非绝对必要,否则我们不能使用javascript。
我当前的表单在我的第一个PHP文档中。单击提交按钮后,它会自行发布以验证和检查数据。我用它来在一个文档中使用PHP进行样式更改。
如果一切都经过验证,它将以刚刚发布的相同数据操作发布到新的PHP。
我的表单是由3个文本输入,一组单选按钮(3个按钮)和一组复选框(4个复选框)构建的。它们全部验证后,我需要将该数据发布到新的PHP文档中进行处理。
这是我当前的代码:
// Are all fields fill
if (isset($_POST['post'])) {
$isCodeCorrect = checkStatusCodeCorrect();
$isTextCorrect = checkStatusTextCorrect();
$isShareOptionCorrect = checkRadioButtonCorrect();
$isDateCorrect = checkDateCorrect();
$isPermissionsCorrect = checkPermissionsCorrect();
if($isCodeCorrect&&$isTextCorrect&&$isShareOptionCorrect&&$isDateCorrect&&$isPermissionsCorrect){
$mainFormAction='action="poststatusprocess.php"';
}
}
function checkStatusCodeCorrect() {
if(!empty($_POST['statusCode'])){
$str1 = $_POST['statusCode'];
//Only S0001 style code
$statusCodePattern = "/^S\d{4}$/";
if(preg_match($statusCodePattern, $str1)){
return true;
}else return false;
}else return false;
}
function checkStatusTextCorrect() {
if(!empty($_POST['statusText'])){
$str2 = $_POST['statusText'];
//Only a-z, A-Z, commas, explanation marks, question marks, apostraphese, and full stops. Case insensitive and global searching and any white space
$statusTextPattern = "/([a-z,!?'\.\s])/i";
if(preg_match($statusTextPattern, $str2)){
return true;
}else return false;
}else return false;
}
function checkRadioButtonCorrect() {
return !empty($_POST['shareOption']);
}
function checkDateCorrect() {
if(!empty($_POST['date'])){
$str3 = $_POST['date'];
//Only 2 digits then forward slash, then 2 digits then forward slash and then only 2 or 4 digits for the year
$datePattern = "/^((\d\d)+\-\d{2}\-\d{2})$/";
if(preg_match($datePattern, $str3)){
return true;
}else return false;
}else return false;
}
function checkPermissionsCorrect(){
if((!empty($_POST['allowLike']))||(!empty($_POST['allowComment']))||(!empty($_POST['allowShare']))||(!empty($_POST['allowNone']))){
return true;
}else return false;
}

如果已安装模块,则可以使用CURL,或者,因为这是家庭作业,您可能希望学习并了解如何手动进行。
/**
* Send a POST request without using PHP's curl functions.
*
* @param string $url The URL you are sending the POST request to.
* @param array $postVars Associative array containing POST values.
* @return string The output response.
* @throws Exception If the request fails.
*/
function post($url, $postVars = array()){
//Transform our POST array into a URL-encoded query string.
$postStr = http_build_query($postVars);
//Create an $options array that can be passed into stream_context_create.
$options = array(
'http' =>
array(
'method' => 'POST', //We are using the POST HTTP method.
'header' => 'Content-type: application/x-www-form-urlencoded',
'content' => $postStr //Our URL-encoded query string.
)
);
//Pass our $options array into stream_context_create.
//This will return a stream context resource.
$streamContext = stream_context_create($options);
//Use PHP's file_get_contents function to carry out the request.
//We pass the $streamContext variable in as a third parameter.
$result = file_get_contents($url, false, $streamContext);
//If $result is FALSE, then the request has failed.
if($result === false){
//If the request failed, throw an Exception containing
//the error.
$error = error_get_last();
throw new Exception('POST request failed: ' . $error['message']);
}
//If everything went OK, return the response.
return $result;
}
(取自here)
此函数将从PHP代码中发送POST请求,然后使用单页表单验证了所有字段后,可以使用以下命令进行调用:
try{
$result = post('processValidated.php', array(
'foo' => 'bar',
'field' => 'Value'
));
echo $result;
} catch(Exception $e){
echo $e->getMessage();
}
如上所述,这实际上不是处理表单输入和数据验证的标准方法。如果是小型独立表单,则无效和有效表单提交都将由一个php脚本处理;如果使用OOP,则由包含的类处理。另外,MVC框架将使用控制器等来验证和处理表单提交并做出相应的响应

只需包含其他文件中的函数,并在所有检查均通过的情况下运行。或者,您可以重定向到新的url,但这将成为获取而不是发布。通常,您将所有发布请求都放在一个地方,然后将http标头重定向到某个结果页面。
