Newbie issue - $_REQUEST don't populate
See original GitHub issueFirst of all, really thanks for W2UI! It’s amazing!
I am a newbie to w2ui and I have serios problems with something really basic.
I am trying to get data from my server (LAMP) but I get always the same (Command “” is not recognized). I did everything that I know. I try for more then 15 hours and nothing.
I get data only when I assembly a array in PHP and encode to Json to pass with an ECO. But I want to make it work with the default method to send request.
I tried to use the example that is in the folder " /server/php " and get the same issue. I try all examples that have server connection.
My $_REQUEST array do not receive data, if I send an var in the url. …php?param=1 I get it into the users.php. But I do not receive $_REQUEST[‘cmd’] and the other vars.
Please some one help me. Thanks in advance.
My code: users.php I did customization in server, user, pass… `<?php
require(“w2db.php”); require(“w2lib.php”);
$db = new dbConnection(“mysql”); $db->connect(“localhost”, “xxx”, “xxx”, “tdr_DB”, “3306”);
switch ($_REQUEST[‘cmd’]) {
case 'get':
if (array_key_exists('recid', $_REQUEST)){ // if true , then is a 'get-record' only one record with recid
$sql = "SELECT userid, fname, lname, email, login, password
FROM users
WHERE userid = ".$_REQUEST['recid'];
$res = $w2grid->getRecord($sql);
}
else{
$sql = "SELECT * FROM users
WHERE ~search~ ORDER BY ~sort~";
$res = $w2grid->getRecords($sql, null, $_REQUEST);
}
$w2grid->outputJSON($res);
break;
case 'delete':
$res = $w2grid->deleteRecords("users", "userid", $_REQUEST);
$w2grid->outputJSON($res);
break;
//case 'get-record':
// break;
case 'save':
$res = $w2grid->saveRecord('users', 'userid', $_REQUEST);
$w2grid->outputJSON($res);
break;
default:
$res = Array();
$res['status'] = 'error';
$res['message'] = 'Command "'.$_REQUEST['cmd'].'" is not recognized.';
$res['postData']= $_REQUEST;
$w2grid->outputJSON($res);
break;
} `

</html>`I created the table in mysql. I am able to get data with my functions…
Sorry this basic question, but I did everything that I know.

@AlexKovynev If you’re using the latest master then “get” will no longer be sent to the server for a “get” request and in addition “cmd” has been renamed to “action” for “delete”/“save” commands.
That means, if the data does not contain an “action” attribute, you should handle it as “get”.
If you’re using 1.5 RC1 then see my answer above.
You could always inspect your browser’s network tab in the dev console to see what exactly gets sent to your server, or just inspect all the data that your server receives.
Thanks for reply. I noticed, than new version make a new problems. 😃 I’ve set w2utils.settings.dataType = ‘JSON’; and url: { get: ‘users.php’, save: ‘users.php’, remove: ‘users.php’ }, and now I get correct JSON string to my users.php (like {“cmd”:“get”,“selected”:[],“limit”:5,“offset”:0}). But I have another issue: users.php (in fact - getRecords() from w2lib.php) returns strange data array looks like: ERROR: Server communication failed. EXPECTED: {status: “success”, total: 5, records: Array(1)} OR: {status: “error”, message: “error message”} RECEIVED: —Array —Array ( [0] => Array ( [0] => 18 )
) —Array ( [0] => Array ( [0] => 1 [1] => Name1 [2] => LastName1 [3] => name1@mail.net [4] => Name1 [5] => 1234567 )
) As result I got error 500 (Internal Server Error) and “AJAX error. See console for more details.” Seems to me, I always receive wrong array and json_encode($data) can’t encode it in JSON string for w2grid(). Buy the way, I can use “add record” button, and add records to MySQL and it works almost correct (do not close popup window after Save). Do you have any idea, what’s wrong with getrecords()? I will appreciate for help. Thanks. PS My code in attached file.
