UTF8 characters not displaying properly with datatables and yadcf
Question
I have a mysql database that is in UTF8, I've properly output the letters before but cannot make my php do so with datatables using the ajax process. I have tried various methods to get the UTF8 to show, including, changing headers, using mysql functions, and changing the json encode function, but I cannot make it work. Please help me show UTF8 properly instead of ?s.
I have: temps.php My server side processing script:
<?php
header("Content-Type: text/json; charset=utf-8");
require( 'ssp.class.php' );
$table = 'articles';
$primaryKey = 'id';
$columns = array(
array( 'db' => 'title', 'dt' => 0 ),
array( 'db' => 'description', 'dt' => 1 ));
$sql_details = array(
'user' => 'root', 'pass' => 'pass', 'db' => 'test', 'host' => 'localhost'
);
$db = SSP::db($sql_details);
.....
if($clause !== ""){
$whereAll[] = $clause;
$_GET['columns'][$i]['search']['value'] = "";
}}
echo json_encode(
SSP::complex( $_GET, $db, $table, $primaryKey, $columns, null,
(!empty($whereAll) ? implode(" AND ", $whereAll) : "")
));
I have: temp.html: My Javascript function (based on datatables and yadcf)
$(document).ready(function(){
$("#example").dataTable({
"responsive": true,
"processing": true,
"serverSide": true,
"ajax": "scripts/temps.php",
"columns": [
// ID
null,
// Distributor
null
// Director
]
}).yadcf([
// ID
{
column_number: 0 ,
filter_type: "text",
filter_reset_button_text: false
},
// Abstract
{
column_number: 1,
filter_type: "text",
filter_delay: 500,
filter_reset_button_text: false
},
]);
});
And I have temp.html where the data is outputted: (redacted because a lot of the code is irrelevant to the question)
<!DOCTYPE html>
<div>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8"/>
<meta name="Description" CONTENT=""/>
..........
<table id="example" class="table table-striped table-bordered table-condensed" cellspacing="0" width="100%">
<thead>
<tr>
<th><div>One</div></th>
<th><div>Two</div></th>
</tr>
</thead>
</table>
Sorry for such a long question; but what else can I change to make UTF8 properly show on the html page? I've tried all the combinations of variables and functions I can think of; but can't make it work. Perhaps there is a js function that could be applied somewhere? Thank you for the help.
Edit: SQL structure for reference:
CREATE TABLE IF NOT EXISTS `articles` (
`id` int(11) NOT NULL,
`title` varchar(300) CHARACTER SET utf8 DEFAULT NULL,
`description` text CHARACTER SET utf8
) ENGINE=InnoDB AUTO_INCREMENT=4 DEFAULT CHARSET=latin1;
-- Dumping data for table `articles`
INSERT INTO `articles` (`id`, `title`, `description`) VALUES
(1, 'శ్రీనివాస్scddadas తామాడా', '新概念英语第asv'),
(2, 'asda', 'asdవా'),
3, 'sdfsadfsdf英语', 'sadf英');

You need to force utf8 in the PDO connection :
$db = SSP::db($sql_details);
$db->exec("set names utf8");
alternatively, try pass it as a param :
$sql_details = array(
'user' => 'root',
'pass' => 'ryan',
'db' => 'edata',
'host' => 'localhost',
'charset' => 'utf8'
);
But this does not work with all PHP versions.
PS: Why do you set the table fields to be of type utf8 , but the table character set to be latin1 ?

If you have added all the columns as "UTF-8" and still the problem persists then try this
Add these lines on the server side file
mysql_query("SET character_set_client=utf8",$gaSql['link']);
mysql_query("SET character_set_connection=utf8",$gaSql['link']);
mysql_query("SET character_set_results=utf8",$gaSql['link']);
