javascript - 从 javascript 到 php 的具有多个数组的数组

Question

我正在尝试从 javascript 获取一些数据到 php。这是一个行数可变的表。所以，我试图用 javascript 循环获取所有数据，然后将它们发送到 php。在那里，我将使用另一个循环来用另一个循环保存每一行。所以，就有了代码:

JavaScript

//---- this is the important section ---- //
var data = new FormData();
var table = [];
for (var i = 1; i <= document.getElementById('nblines').value; i++) {
    var date = document.getElementById('date' + i).innerHTML;
    if (document.getElementById('l' + i).checked == true) { var type = 1;} else { var type = 2;}
    var paiement = document.getElementById('a' + i).innerHTML;
    var tps = document.getElementById('b' + i).innerHTML;
    var tvq = document.getElementById('c' + i).innerHTML;
    var total = document.getElementById('d' + i).innerHTML;
    var interet = document.getElementById('e' + i).innerHTML;
    var principal = document.getElementById('f' + i).innerHTML;
    var balance = document.getElementById('g' + i).innerHTML;
    var line = [i,date,type,type,paiement,tps,tvq,total,interet,principal,total];
    table.push(line);
};
console.log(table);
data.append('amortTable', table);

|                                              |
| ---- this is the NOT important section ----  |
|                                              |
------------------------------------------------


var token = document.getElementById("csrf_token").content;
var request = new XMLHttpRequest();
request.onreadystatechange = function notify()
{
    if (request.readyState === XMLHttpRequest.DONE) {
        if (request.status === 200) {
            setTimeout(loadPage(page),500);
            $.niftyNoty({
                type: 'success',
                container : 'floating',
                html : 'Votre calcul s\'est enregistré avec succès!',
                timer : 5000
            });
        } else {
        }
    } else {
        // still not ready
    }
}
request.open( "POST", "savecalcul", true);
request.setRequestHeader("X-CSRF-TOKEN", token);
request.send(data);

PHP

foreach ($request->input('amortTable') as $i) {
    $line = new Amortissement;
    $line -> calcul()   -> associate($calcul->id);
    $line -> number = $i[0];
    $line -> date = $i[1];
    $line -> type = $i[2];
    $line -> paiement = $i[3];
    $line -> tps = $i[4];
    $line -> tvq = $i[5];
    $line -> total = $i[6];
    $line -> interet = $i[7];
    $line -> principal = $i[8];
    $line -> total = $i[9];
    $line -> save();
}

我收到此错误 local.ERROR: 异常 'ErrorException' 并带有消息 '为 foreach() 提供的参数无效' ... 该行是:

    foreach ($request->input('amortTable') as $i) {

那么，我的方法正确吗？如果是，我做错了什么。如果我没有走对路，我该怎么办？

问题出在这一行:

for (var i = 1; i >= document.getElementById('nblines').value; i++) {

应该是:

for (var i = 1; i <= document.getElementById('nblines').value; i++) {
