Problem with master_detail.php

QuestionsProblem with master_detail.php
Paolo D. asked 3 years ago

I'm trying to test the master_detail.php example on MS Sql server.
My code is:

<?php

/**
* PHP Grid Component
*
* @author Abu Ghufran <[email protected]> – http://www.phpgrid.org
* @version 2.0.0
* @license: see license.txt included in package
*/

$db_conf = array();
$db_conf["type"] = "mssqlnative"; // or mssql
$db_conf["server"] = "my server"; // ip:port
$db_conf["user"] = "my user";
$db_conf["password"] = "my password";
$db_conf["database"] = "my db";

include("/lib/inc/jqgrid_dist.php");
// master grid

$grid = new jqgrid($db_conf);

$opt["caption"] = "Clients Data";
$opt["width"] = 600;
$grid->set_options($opt);
$grid->table = "clients";
// generate grid output, with unique grid name as 'list1'
$out_master = $grid->render("list1");

// second grid
$grid = new jqgrid($db_conf);

$opt["sortname"] = 'id'; // by default sort grid by this field
$opt["sortorder"] = "desc"; // ASC or DESC
$opt["height"] = ""; // autofit height of subgrid
$opt["caption"] = "Invoice Data"; // caption of grid
$opt["width"] = 800;
$opt["multiselect"] = true; // allow you to multi-select through checkboxes
$opt["export"] = array("filename"=>"my-file", "sheetname"=>"test"); // export to excel parameters
$grid->set_options($opt);

$grid->set_actions(array(
"add"=>true, // allow/disallow add
"edit"=>true, // allow/disallow edit
"delete"=>true, // allow/disallow delete
"rowactions"=>true, // show/hide row wise edit/del/save option
"export"=>true, // show/hide export to excel option
"autofilter" => true, // show/hide autofilter for search
"search" => "advance" // show single/multi field search condition (e.g. simple or advance)
)
);

// this db table will be used for add,edit,delete
$grid->table = "invheader";

// generate grid output, with unique grid name as 'list2'
$out_detail = $grid->render("list2");

?>

</head>
<body>
<div style="margin:10px">
<?php echo $out?>
</div>
</body>
</html>

The code is very similar to the example, I had only to change db connection.

The result is a blank page. Just to be sure I tried each table separately and they show correctly (obv. I had to change last row from out_detail to simply out).
I tried with error message on but no error message is displayed.
Via firefox/firebug I got this error 500 but I have no idea what's wrong:

I have version phpgrid-full-v2.0 (received via email on 13/9/2016), I don't know if it's the latest

Any idea?

Fixed. The problem was an error in the HTML code

<?php echo $out?>

instead of

<?php echo $out_master ?>
<br>
<?php echo $out_detail; ?>
</div>
