如何在另一个表单上提交后保留数组中的数据



所有人，

首先，我很抱歉这个问题有点令人困惑。

问题是：几天前我发布了另一个问题(这个问题)，关于我们老师给我们的一个练习，这有点棘手，换句话说，这项工作包括将从表格中收集的数据(事实上是几个数据)保存在一个数组中，然后能够在不删除数组中其他数据的情况下修改它们。

正如我在上一篇文章中所说，糟糕的是我们不能使用会话、数据库、文件或本地存储。

注意：我在一个页面中完成所有操作，因为这是保存我找到的数据的最佳方式

他告诉我们，诀窍是使用json_encode()在隐藏的输入中传递数据，到目前为止一切都很好，多亏了上一篇文章中的答案，只要NID还不在数组中，我就设法保存了多个用户，但在我们必须更新数据的部分，一切都变得复杂起来。要更新数据，我要做的第一件事是要求用户的NID用select/选项进行修改，但当我提交select时，它会删除我在$agenda变量中添加的用户的数据。

我确信问题出在isset()上，但我做这个练习已经一周了，我想不出什么新的了。

这是index.php:的代码

<?php
require_once './controllers/modules.php';
if(!isset($_POST['hiddenInputUpdate'])) {
$newAgenda = [];
} else {
$newAgenda = decodeData();
updateData($newAgenda);
}
if(!isset($_POST['hiddenInputReg'])) {
$agenda = [];
} else {
$agenda = decodeData();
addData($agenda);
}
print('<pre>'.print_r($agenda, true).'</pre>');
?>

这是modules.hp:

return json_encode($data);
}
function decodeData() {
return json_decode($_POST['hiddenInputReg'], true);
}
function cleanData($data) {
$data = trim($data);
$data = stripslashes($data);
$data = htmlspecialchars($data);
return $data;
}
function addData(&$data) {
$date = getLocalTime();
if(!in_array($_POST['regNid'], $data) || empty($data)) {
$data[$_POST['regNid']]['nombre'] = cleanData($_POST['regName']);
$data[$_POST['regNid']]['apellidos'] = cleanData($_POST['regSurname']);
$data[$_POST['regNid']]['correo'] = cleanData($_POST['regEmail']);
$data[$_POST['regNid']]['telefono'] = cleanData($_POST['regTel']);
$data[$_POST['regNid']]['fechaNacimiento'] = cleanData($_POST['regBirth']);
$data[$_POST['regNid']]['fechaInsercion'] = $date;
$data[$_POST['regNid']]['bloqueado'] = false;
$data[$_POST['regNid']]['ficheros'] = [];
return;
}
return;
}
function updateData(&$data) {
if(!in_array($_POST['regNid'], $data) || empty($data)) {
$data[$_POST['regNid']]['nombre'] = cleanData($_POST['regName']);
$data[$_POST['regNid']]['apellidos'] = cleanData($_POST['regSurname']);
$data[$_POST['regNid']]['correo'] = cleanData($_POST['regEmail']);
$data[$_POST['regNid']]['telefono'] = cleanData($_POST['regTel']);
$data[$_POST['regNid']]['fechaNacimiento'] = cleanData($_POST['regBirth']);
$data[$_POST['regNid']]['ficheros'] = $_FILES['updateFile']['name'];
return;
}
return;
}
?>

注意：我还没有使用updateDate()函数，但我更喜欢将其添加到帖子中以防万一

总之，我想要实现的是保持使用#regForm添加的数据，即使我在#getNidForm或#updForm上提交。

最后，它很简单，只需使用相同的隐藏输入#regForm传递每个表单中的数据；您还需要在考虑提交按钮(regSubmit、updSubmit或blockSubmit)的情况下更改条件(isset())，因为它们每个都使用不同的函数，如addData、updateData或setBlock。

如果有人和我有同样的问题，有同样的否决权，我把最后的代码留在这里：

if(!isset($_POST['hiddenInputReg'])) {
$agenda = [];
} else {
$agenda = decodeData();
if(isset($_POST['regSubmit'])) {
addData($agenda);
} 
else if(isset($_POST['updSubmit'])) {
updateData($agenda);
}
else if(isset($_POST['blockSubmit'])) {
setBlock($agenda);
}
}
print('<pre>'.print_r($agenda, true).'</pre>');

$data = stripslashes($data);
// $data = htmlspecialchars($data);
return $data;
}
function addData(&$data) {
$date = getLocalTime('datetime');
if(!in_array($_POST['regNid'], $data) || empty($data)) {
$data[$_POST['regNid']]['nombre'] = cleanData($_POST['regName']);
$data[$_POST['regNid']]['apellidos'] = cleanData($_POST['regSurname']);
$data[$_POST['regNid']]['correo'] = cleanData($_POST['regEmail']);
$data[$_POST['regNid']]['telefono'] = cleanData($_POST['regTel']);
$data[$_POST['regNid']]['fechaNacimiento'] = cleanData($_POST['regBirth']);
$data[$_POST['regNid']]['fechaInsercion'] = $date;
$data[$_POST['regNid']]['bloqueado'] = false;
$data[$_POST['regNid']]['ficheros'] = [];
}
return;
}
function updateData(&$data) {
$data[$_POST['updateNid']]['nombre'] = cleanData($_POST['updateName']);
$data[$_POST['updateNid']]['apellidos'] = cleanData($_POST['updateSurname']);
$data[$_POST['updateNid']]['correo'] = cleanData($_POST['updateEmail']);
$data[$_POST['updateNid']]['telefono'] = cleanData($_POST['updatePhone']);
$data[$_POST['updateNid']]['fechaNacimiento'] = cleanData($_POST['updateBirth']);
$data[$_POST['updateNid']]['ficheros'][] = cleanData($_FILES['updateFile']['name']);
}
function setBlock(&$data) {
$data[$_POST['block']]['bloqueado'] = !$data[$_POST['block']]['bloqueado'];
}
?>

可能有一些垃圾代码(一些打印或一些不必要的部分)，因为我刚刚解决了它，所以我更喜欢直接上传我所拥有的。

除了将hiddenInputReg放在其他形式或表中(数据更改的地方)之外，关键是调用htmlspecialchar()函数，包装hiddenInputReg的encodeData()；理论上不在"；updSubmit()"形式(在回声中)导致$agenda数组数据看起来是"0"；空"；在updateData()函数中，当然是因为引号的原因，它用htmlspecialchar()为我解决了这个问题，我也把它放在了其他encodeData()中以防万一，但我认为删除除了echos中的所有内容，它应该没问题。
