How To Add A Where Condition To Server Side Processing PHP

gbyrd

I need to ad a "WHERE" condition to my results. But am to sure where to add it exactly.

If I were writing straight PHP I would add this: to my query: WHERE user_id = '2'

But with using DataTables, I am to sure where to add that condition. I did read through the information o this page: https://editor.datatables.net/manual/php/conditions#Simple-usage
But that does not tell you where you should add that ... it just gives an example like $editor->where( 'user_id', 12 ); and doesn't give any examples of where you would use that ... I presume in the server_processing.php file.

I am using server side processing and my script looks like this:

<?php

/*
 * DataTables example server-side processing script.

 * @license MIT - http://datatables.net/license_mit
 */

/* * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * *
 * Easy set variables
 */

// DB table to use
$table = 'links';

// Table's primary key
$primaryKey = 'id';


// 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' => 'id', 'dt' => 0 ),
    array( 'db' => 'title',  'dt' => 1 ),
    array( 'db' => 'url',  'dt' => 2 ),
    array( 'db' => 'created',  'dt' => 3 )
);

// SQL server connection information
$sql_details = array(
    'user' => 'xxx',
    'pass' => '*xxx',
    'db'   => 'xxx',
    'host' => '108.xxx.xxx.xxx'
);


/* * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * *
 * If you just want to use the basic configuration for DataTables with PHP
 * server-side, there is no need to edit below this line.
 */

require( 'ssp.class.php' );

echo json_encode(
    SSP::simple( $_GET, $sql_details, $table, $primaryKey, $columns )
);

This thread should help, it's asking the same thing.

@colin
That was perfect! It worked and only took about 3 seconds to implement.

Thank you!

For others who may be reading this and are looking for an answer to the same question ...

If you take a look at line 50 in the above code snippet ... it reads:

SSP::simple( $_GET, $sql_details, $table, $primaryKey, $columns )

I changed that to read
SSP::complex( $_GET, $sql_details, $table, $primaryKey, $columns, null, "user_id = '2'" )

"user_id" is the name of the column WHERE I want to look for all the entries by "2" ...
