Send array with Ajax to PHP script
提问by Paul Attuck
I have array made by function .push. In array is very large data. How is the best way send this to PHP script?
我有由函数.push制作的数组。在数组中是非常大的数据。将它发送到 PHP 脚本的最佳方式是什么？
dataString = ??? ; // array?
$.ajax({
type: "POST",
url: "script.php",
data: dataString,
cache: false,
success: function(){
alert("OK");
}
});
script.php:
脚本.php：
$data = $_POST['data'];
// here i would like use foreach:
foreach($data as $d){
echo $d;
}
How is the best way for this?
最好的方法是什么？

Encode your data string into JSON.
将您的数据字符串编码为 JSON。
dataString = ??? ; // array?
var jsonString = JSON.stringify(dataString);
$.ajax({
type: "POST",
url: "script.php",
data: {data : jsonString},
cache: false,
success: function(){
alert("OK");
}
});
In your PHP
在你的 PHP
$data = json_decode(stripslashes($_POST['data']));
// here i would like use foreach:
foreach($data as $d){
echo $d;
}
Note
笔记
When you send data via POST, it needs to be as a keyvalue pair.
当您通过 POST 发送数据时，它需要作为一个键值对。
Thus
因此
data: dataString
data: dataString
is wrong. Instead do:
是错的。而是这样做：
data: {data:dataString}
data: {data:dataString}

dataString = [];
$.ajax({
type: "POST",
url: "script.php",
data:{data: $(dataString).serializeArray()},
cache: false,
success: function(){
alert("OK");
}
});

Data in jQuery ajax()function accepts anonymous objects as its input, see documentation. So example of what you're looking for is:
jQueryajax()函数中的数据接受匿名对象作为其输入，请参阅文档。所以你正在寻找的例子是：
dataString = {key: 'val', key2: 'val2'};
$.ajax({
type: "POST",
url: "script.php",
data: dataString,
cache: false,
success: function(){
alert("OK");
}
});
You may also write POST/GET query on your own, like key=val&key2=val2, but you'd have to handle escaping yourself which is impractical.
您也可以自己编写 POST/GET 查询，例如key=val&key2=val2，但您必须自己处理逃避，这是不切实际的。

dataString suggests the data is formatted in a string (and maybe delimted by a character).
dataString 表明数据格式为字符串（并且可能由字符分隔）。
$data = explode(",", $_POST['data']);
foreach($data as $d){
echo $d;
}
if dataString is not a string but infact an array (what your question indicates) use JSON.
如果 dataString 不是字符串而是实际上是数组（您的问题所指的），请使用 JSON。

If you have been trying to send a one dimentional array and jquery was converting it to comma separated values >:(then follow the code below and an actual array will be submittedto phpand not all the comma separated bull**it.
如果您一直在尝试发送一维数组并且jquery 正在将其转换为逗号分隔值 >:(然后按照下面的代码将实际数组提交给php而不是所有逗号分隔的公牛**它。
Say you have to attach a single dimentional array named myvals.
假设您必须附加一个名为myvals.
jQuery('#someform').on('submit', function (e) {
e.preventDefault();
var data = $(this).serializeArray();
var myvals = [21, 52, 13, 24, 75]; // This array could come from anywhere you choose
for (i = 0; i < myvals.length; i++) {
data.push({
name: "myvals[]", // These blank empty brackets are imp!
value: myvals[i]
});
}
jQuery.ajax({
type: "post",
url: jQuery(this).attr('action'),
dataType: "json",
data: data, // You have to just pass our data variable plain and simple no Rube Goldberg sh*t.
success: function (r) {
...
Now inside phpwhen you do this
现在php当你这样做的时候里面
print_r($_POST);
You will get ..
你会得到 ..
Array
(
[someinputinsidetheform] => 023
[anotherforminput] => 111
[myvals] => Array
(
[0] => 21
[1] => 52
[2] => 13
[3] => 24
[4] => 75
)
)
Pardon my language, but there are hell lot of Rube-Goldbergsolutions scattered all over the web and specially on SO, but none of them are elegant or solve the problem of actually posting a one dimensional array to phpvia ajax post. Don't forget to spread this solution.
请原谅我的语言，但是有很多Rube-Goldberg解决方案散布在整个网络上，特别是在 SO 上，但没有一个是优雅的，也没有解决通过 ajax post实际发布一维数组php的问题。不要忘记传播这个解决方案。
