Passing arguments to sAjaxSource in jQuery datatables
提问by Rishi Reddy
I am working with CodeIgniter and I have the following problem.
我正在使用 CodeIgniter，但遇到以下问题。
I have a controller function in details.phpwhich takes an argument:
我有一个控制器函数，details.php它接受一个参数：
function details($id) {
$this->datatables
->select('product_id, original_amount, quantity')
->from('orders');
echo $this->datatables->generate();
}
Now I need to call this from views, i.e. I want DataTables to display it like so:
现在我需要从视图中调用它，即我希望 DataTables 像这样显示它：
<script>
$(document).ready(function()
$('#example').dataTable({
...
'sAjaxSource' : 'admin/data/details',
...
});
</script>
So, how do I pass arguments to the sAjaxSourcekey, namely the $idvariable?
那么，我如何将参数传递给sAjaxSource键，即$id变量？

You should use fnServerParamsas specified in the docs.
您应该fnServerParams按照文档中的说明使用。
$(document).ready(function() {
$('#example').dataTable( {
"bProcessing": true,
"bServerSide": true,
"sAjaxSource": "scripts/server_processing.php",
"fnServerParams": function ( aoData ) {
aoData.push( { "name": "more_data", "value": "my_value" } );
}
} );
} );

I was struggling with this issue myself. The answer of John Moses didn't work for me, also the link he provides links to the new documentation which, I think, does not count for older versions of datatables.
我自己也在努力解决这个问题。约翰摩西的回答对我不起作用，他提供的链接也指向新文档的链接，我认为这不计入旧版本的数据表。
Although, I found out that the current server side processing is working like jQuery, where older versions with "sAjaxSource" don't work that way.
虽然，我发现当前的服务器端处理像 jQuery 一样工作，其中带有“sAjaxSource”的旧版本不能那样工作。
For me, I just simpely added my parameters in the url of the sAjaxSource. So in your example code:
对我来说，我只是在sAjaxSource. 所以在你的示例代码中：
$customPHPvar = "mycustomvar";
<script>
$(document).ready(function() {
$('#example').dataTable( {
"bProcessing": true,
"bServerSide": true,
"sAjaxSource": "scripts/server_processing.php?customvar=<?php echo $customPHPvar; ?>",
} );
} );
</script>
in server_processing.php
在 server_processing.php 中
$_GET['customvar'];
