Question

他们关于此的文档（datatables.net）似乎隐藏在一些庞大的PHP教程中。我找到的是：http://datatables.net/development/server-side/php_mysql

所有我想知道的，是如何创建一个数组，使用PHP，稍后将使用静态数据（无变量）的json_encode（）来填充一个包含几个列标题和几个示例行的表数据。其中一些来自上面的教程。

<?php
    $output = array(
        "sEcho" => intval($_GET['sEcho']), //no idea what this is
        "iTotalRecords" => $iTotal, //probably total records
        "iTotalDisplayRecords" => $iFilteredTotal, //Not sure, records per page?
        "aaData" => array() //setting the data array for the rows
        );
    $output['aaData'][] = //each row here, unsure of format

    //Where do the column titles go, and the format for those?
?>
<script type="text/javascript">
    $(document).ready(function() {

        var aDataSet = <?php echo json_encode($output); ?>

        $('#demo').html( '<table cellpadding="0" cellspacing="0" border="0" class="display" id="example"></table>' );
        $('#example').dataTable( {
            "aaData": aDataSet,
            "aoColumns": aoDataSet //This would be a second json_encode PHP array, set to var aoDataSet
        } ); 
    } );
</script>

任何帮助都将不胜感激。

编辑：在user2657979的回答的帮助下，我现在回答了我的问题。下面是从PHP数组中填充DataTables标题和数据的答案。

<?php
$aoColumnDefs = array(
    array(
        'sTitle'   => 'Column 1',
        'aTargets' => array(0) 
    ),
    array(
        'sTitle'   => 'Column 2',
        'aTargets' => array(1) 
    ),
    array(
        'sTitle'   => 'Column 3',
        'aTargets' => array(2) 
    ),
    array(
        'sTitle'   => 'Column 4',
        'aTargets' => array(3) 
    ),
    array(
        'sTitle'   => 'Column 5',
        'aTargets' => array(4) 
    )
);

$aoRowDefs = array(
    0   =>  array(
        0   =>  "Row 1 data Column 1", 
        1   =>  "Row 1 data Column 2",
        2   =>  "Row 1 data Column 3",
        3   =>  "Row 1 data Column 4",
        4   =>  "Row 1 data Column 5"
        ),
    1   =>  array(
        0   =>  "Row 2 data Column 1",
        1   =>  "Row 2 data Column 2",
        2   =>  "Row 2 data Column 3",
        3   =>  "Row 2 data Column 4",
        4   =>  "Row 2 data Column 5"
        ),
    2   =>  array(
        0   =>  "Row 3 data Column 1",
        1   =>  "Row 3 data Column 2",
        2   =>  "Row 3 data Column 3",
        3   =>  "Row 3 data Column 4",
        4   =>  "Row 3 data Column 5"
        )
    );
?>

<script type="text/javascript">

    var aoRowDefs = <?php echo json_encode($aoRowDefs); ?>

    var aoColumnDefs = <?php echo json_encode($aoColumnDefs); ?>

    $(document).ready(function() {
        $('#demo').html( '<table cellpadding="0" cellspacing="0" border="0" class="display" id="example"></table>' );
        $('#example').dataTable( {
        "aaData": aoRowDefs,
        "aoColumns": aoColumnDefs
        } ); 
    } );
</script>

<div id="demo">
    <div id="example">
    </div>
</div>

我的数据表没有动态标题，所以我在javascript中的配置中定义它们。

"aoColumns": [{
        "sTitle": "Column 1"
    }, {
        "sTitle": "Column 2"
    }, {
        "sTitle": "Column 3"
    }, {
        "sTitle": "Column 4"
    }, {
        "sTitle": "Column 5"
    }]

插件的创建者现在建议使用aoColumnDefs，然后指定列的目标。

"aoColumnDefs": [{
        "sTitle": "Column 1",
        "aTargets": [0]
    }, {
        "sTitle": "Column 2",
        "aTargets": [1]
    }, {
        "sTitle": "Column 3",
        "aTargets": [2]
    }, {
        "sTitle": "Column 4",
        "aTargets": [3]
    }, {
        "sTitle": "Column 5",
        "aTargets": [4]
    }]

如果某些操作会影响多个列，则aoColumnDefs可以提供更大的灵活性，允许您指定多个列。

但是，如果您的列标题是动态的，则可以将json编码的数组传递给javascript中的配置。

$aoColumnDefs = array(
    array(
        'sTitle'   => 'Column 1',
        'aTargets' => array(0) 
    )
);
$aoColumnDefsEndcoded = json_encode($aoColumnDefs);
