DataTables | How to do your own select? - php

Question

Hello i use the tablesorter-plugin DataTables.
I use it with serverside processing and ajax pipelining.
Here is my actual serverside script:
<?php
// Datenbank-Tabelle, die verwendet wird
$table = 'loginlogs';
// Der Primary key, der Tabelle
$primaryKey = 'id';
// Das "datetime"-Format aus der Datenbank extrahieren, nur das Datum (in das Deutsche-Format)
function getonlydate($datetime){
$exploded = explode("-", $datetime);
$explodemeagain = explode(" ", $exploded[2]);
$mergeme = $explodemeagain[0].".".$exploded[1].".".$exploded[0];
return $mergeme;
}
// Das "datetime"-Format aus der Datenbank extrahieren, nur die Uhrzeit
function getonlytime($datetime){
$exploded = explode("-", $datetime);
$explodemeagain = explode(" ", $exploded[2]);
$mergeme = $explodemeagain[1];
return $mergeme;
}
// Array of database columns which should be read and sent back to DataTables.
// The `db` parameter represents the column name in the database, while the `dt`
// parameter represents the DataTables column identifier. In this case simple indexes.
$columns = array(
array( 'db' => 'ip', 'dt' => 0 ),
array(
'db' => 'status',
'dt' => 1,
'formatter' => function( $d, $row ) {
if($d == 1){
return "Erfolgreich";
}else{
return "Fehlgeschlagen";
}
}
),
array(
'db' => 'stayloggedin',
'dt' => 2,
'formatter' => function( $d, $row ) {
if($d == 1){
return "Ja";
}else{
return "Nein";
}
}
),
array(
'db' => 'date',
'dt' => 3,
'formatter' => function( $d, $row ) {
return getonlydate($d);
}
),
array(
'db' => 'date',
'dt' => 4,
'formatter' => function( $d, $row ) {
return getonlytime($d);
}
)
);
// SQL server connection information
require('../../phpfuncs/connection.php');
$sql_details = array(
'user' => $user,
'pass' => $pw,
'db' => $db,
'host' => $host
);
require('ssp.class.php');
echo json_encode(
SSP::simple( $_GET, $sql_details, $table, $primaryKey, $columns )
);
?>
Now my question is how can i do specific selects?
A specific select like:
"SELECT * FROM ".$table." WHERE userid=16"
I already searched on their website for some documentations but i can only find docs about filtering, and so on. Clientside stuff, but nothing about specific serverside possibilities.
Maybe somebody also use datatables and tablesorter and can help me out with an example?

You can use another method SSP::complex. From the comments in the code:
The difference between this method and the simple one, is that you
can apply additional where conditions to the SQL queries. These can
be in one of two forms:
'Result condition' ($whereResult) - This is applied to the result set, but not the
overall paging information query - i.e. it will not effect the number
of records that a user sees they can have access to. This should be
used when you want apply a filtering condition that the user has sent.
'All condition' ($whereAll) - This is applied to all queries that are made and
reduces the number of records that the user can access. This should be
used in conditions where you don't want the user to ever have access
to particular records (for example, restricting by a login id).
Function accepts the following arguments:
SSP::complex ($request, $conn, $table, $primaryKey, $columns, $whereResult=null, $whereAll=null)
So in order to apply the SQL query with WHERE condition, you need to change your code as follows:
echo json_encode(
SSP::complex( $_GET, $sql_details, $table, $primaryKey, $columns, null, "userid=16" )
);
