UTF-8 all the way through
(13 answers)
Closed 8 years ago.
Im trying to add some text with this command, included in my php file:
$sql = "INSERT INTO $this->table_name_category (name, marker_icon) VALUES ('".$name."', '".$marker_icon."')";
Everything looks fine in English characters, but in GREEK one's, the parsed text is being converted to question marks "??????"
Is there something else that i must take care off? Is there a way to tell INSERT command to use UTF8 in order to support Greek characters?
Thanks in advance.
My database is set to utf8_unicode_ci (tables too).

before you do any query or CRUD in mysql issue this command
"SET NAMES utf8"
"SET CHARACTER SET utf8"
in PHP...
mysql_query("SET NAMES utf8");
to make sure everything is in UTF-8 and you use PDO... modify your PDO connection into this
depending on what API you use
$pdo = new PDO(
'mysql:host=hostname;dbname=defaultDbName',
'username',
'password',
array(PDO::MYSQL_ATTR_INIT_COMMAND => "utf8")
);
reference:
Accented characters in mySQL table
Couple of things to check are the connection and the column. Columns can have their own char set
http://www.php.net/manual/en/mysqli.set-charset.php
http://dev.mysql.com/doc/refman/5.0/en/charset-column.html
1.Use show create table X to see the encoding of the table.
something like:
mysql> show create table user;
+-------+---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+
| Table | Create Table |
+-------+---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+
| user | CREATE TABLE `user` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`name` varchar(255) DEFAULT NULL,
`password` varchar(64) DEFAULT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=3 DEFAULT CHARSET=utf8 |
+-------+---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+
1 row in set (0.00 sec)
2.If charset is not utf8, change it such.
mysql> alter table y character set 'utf8';

I am trying to insert PHP variables in a mysql table, where the table name is also a variable, using mysqli_query. I've tried multiple solutions from stackoverflow but it still does not work.
I try to do it like this, maybe I am missing something. Thank you in advance!
<?php
session_start();
#include_once "modules/connections/dbconn.php";
$value = $_POST['value'];
$playerid = $_SESSION["steamid"];
$playername = fetchinfo("name","users","steamid",$playerid);
$playeravatar = fetchinfo("avatar","users","steamid",$playerid);
$playercoins = fetchinfo("coins", "users","steamid",$playerid);
if($playercoins - $value < 0){
die(json_encode(array('message' => 'ERROR', 'code' => "Not enough coins!")));
}
$game = fetchinfo("value","parameters","name","raffleRound");
$maxitems = fetchinfo("value","parameters","name","raffleMaxritems");
$items = fetchinfo("itemsnum","rafflegames","id",$game);
$itemname = "Coins";
$itemavatar = "images/creditcardicon.png";
$color = "D2D2D2";
$initialvalue = fetchinfo("value","rafflegames","id",$game);
$from = $initialvalue * 100;
$to = $from + $value * 100;
$tablename = 'rafflegame'.$game;
if($items < $maxitems){
mysqli_query($GLOBALS["connect"], "UPDATE rafflegames SET `value`=`value`+$value, `itemsnum`=`itemsnum`+1 WHERE `id`=$game");
mysqli_query($GLOBALS["connect"], "UPDATE users SET `coins`=`coins`-$value WHERE `steamid`=$playerid");
mysqli_query($GLOBALS["connect"], "INSERT INTO `" . $tablename . "` VALUES ('".$playerid."', '".$playername."','".$itemname."','".$color."','".$value."','".$playeravatar."','".$itemavatar."','".$from."','".$to."')");
}
else {
die(json_encode(array('message' => 'ERROR', 'code' => "Too many items in the current game")));
}
?>
The other two queries work just fine.
The table structure is this:
mysqli_query($GLOBALS['connect'],"CREATE TABLE `rafflegame$roundNumber` (
`id` int(11) NOT NULL auto_increment,
`userid` varchar(70) NOT NULL,
`username` varchar(70) NOT NULL,
`item` text,
`color` text,
`value` float,
`avatar` varchar(512) NOT NULL,
`image` text NOT NULL,
`from` int NOT NULL,
`to` int NOT NULL,
PRIMARY KEY (`id`)
) ENGINE=MyISAM AUTO_INCREMENT=1 DEFAULT CHARSET=utf8 AUTO_INCREMENT=1;");
mysqli_query($GLOBALS['connect'],"TRUNCATE TABLE `rafflegame$roundNumber`");
There is difference between table structure and insert column coumnt, When you want id column as auto incremented in that case column name should be included in insert query.
Please use the code as below:
<?php
session_start();
#include_once "modules/connections/dbconn.php";
$value = $_POST['value'];
$playerid = $_SESSION["steamid"];
$playername = fetchinfo("name","users","steamid",$playerid);
$playeravatar = fetchinfo("avatar","users","steamid",$playerid);
$playercoins = fetchinfo("coins", "users","steamid",$playerid);
if($playercoins - $value < 0){
die(json_encode(array('message' => 'ERROR', 'code' => "Not enough coins!")));
}
$game = fetchinfo("value","parameters","name","raffleRound");
$maxitems = fetchinfo("value","parameters","name","raffleMaxritems");
$items = fetchinfo("itemsnum","rafflegames","id",$game);
$itemname = "Coins";
$itemavatar = "images/creditcardicon.png";
$color = "D2D2D2";
$initialvalue = fetchinfo("value","rafflegames","id",$game);
$from = $initialvalue * 100;
$to = $from + $value * 100;
$tablename = 'rafflegame'.$game;
if($items < $maxitems){
mysqli_query($GLOBALS["connect"], "UPDATE rafflegames SET `value`=`value`+$value, `itemsnum`=`itemsnum`+1 WHERE `id`=$game");
mysqli_query($GLOBALS["connect"], "UPDATE users SET `coins`=`coins`-$value WHERE `steamid`=$playerid");
mysqli_query($GLOBALS["connect"], "INSERT INTO `" . $tablename . "`(`userid`,`username`,`item`,`color`,`value`,`avatar`,`image`,`from`,`to`) VALUES ('".$playerid."', '".$playername."','".$itemname."','".$color."','".$value."','".$playeravatar."','".$itemavatar."','".$from."','".$to."')");
}
else {
die(json_encode(array('message' => 'ERROR', 'code' => "Too many items in the current game")));
}
?>

I'm trying to figure how to call a query once.
I have 6 different variables for images, title and desc.
In this code, I need to know how to loop for id from 0 to 6.
$date = new DateTime("NOW");
$image1 = 'SSSS';
$title1 = 'AAAA';
$desc1 = 'BBBB';
$image2 = 'RRRR';
$title2 = 'GGGG';
$desc2 = 'VVVV';
/// 4 vars later....
$id = 6;
$get = $this->db->queryRow("UPDATE `featured` SET `image` = '{$image.$id}', `title` = '{$title.$id}', `desc` = '{$desc.$id}', `date` = '{$date->format('Y-m-d H:i:s')}' WHERE id = '{$id}'");
return(object) $get;
To build a collection of Querys use the multi_query function.
Loop to build your Query string to pass to the db and concatenated by a semicolon.
<?php
for($i=0;$i <= $maxquerys;$i++){
$query = "UPDATE `featured` SET `image` = '".$image.$id."', `title` = ".$title.$id."', `desc` = '".$desc.$id."', `date` = '".$date->format('Y-m-d H:i:s')."' WHERE id = '".$id."';"
}
/* execute multi query */
if ($mysqli->multi_query($query)) {
while ($mysqli->next_result());
}
/* close connection */
$mysqli->close();
you may check also the result by
echo $mysqli->affected_rows;
?>
I have tried to use a simple $query model and it works fine.
Create a valid Query string to pass to the db
<?php
$query = "UPDATE `featured` SET `image` = '".$image.$id."', `title` = ".$title.$id."', `desc` = '".$desc.$id}."', `date` = '".$date->format('Y-m-d H:i:s')."' WHERE id = '".$id."';"
$result=$mysqli->query($query);
// Verify results
if(!$result) {
$ErrMessage = "ErrSqlQuery:" . $mysqli->error . "\n";
$mysqli->close();
die($ErrMessage);
}
you can check also the result by
echo $mysqli->affected_rows;
?>
$query_build = "";
foreach($arr as $$image){
$query_build .= "UPDATE `featured` SET `image` = '{$image.$id}', `title` = '{$title.$id}', `desc` = '{$desc.$id}', `date` = '{$date->format('Y-m-d H:i:s')}' WHERE id = '{$id}';";
}
$get = $this->db->queryRow($query_build);
Accumulate all the queries and execute all at once.
I have 2 tables structured like this:
CREATE TABLE `exp_ws_gk_text` (
`WGT_RID` INT(9) NOT NULL AUTO_INCREMENT,
`WGT_PRG_CODE` VARCHAR(5) NOT NULL,
`WGT_TEXT` VARCHAR(4000) NOT NULL,
INDEX `PrimaryKey` (`WGT_RID`)
)
CREATE TABLE `exp_ws_gk_state` (
`WGS_RID` INT(9) NOT NULL AUTO_INCREMENT,
`WGS_TYPE` INT(9) NOT NULL,
`WGS_STATE` VARCHAR(3) NOT NULL,
`WGS_WGT_RID` INT(9) NOT NULL,
INDEX `PrimaryKey` (`WGS_RID`),
INDEX `SecondaryKey` (`WGS_TYPE`, `WGS_STATE`)
)
This is how I query the data to be used in a site:
SELECT a.wgt_rid id, a.wgt_text text, a.wgt_prg_code prg_code,
b.wgs_state state, b.wgs_type type,
FROM exp_ws_gk_text a, exp_ws_gk_state b
WHERE a.wgt_rid = b.wgs_wgt_rid
I present the record with all the data returned. Now, when I want to edit or append a record, how would I save the data correctly if the data got sent from a form with these parameters:
$id = intval($_REQUEST['id']);
$prg_code = $_REQUEST['prg_code'];
$state = $_REQUEST['state'];
$crs_type = $_REQUEST['type'];
$text = $_REQUEST['text'];
An insert:
$sql = "BEGIN; ".
" INSERT INTO exp_ws_gk_text (WGT_PRG_CODE, WGT_TEXT) ".
" VALUES('".$prg_code."', '".$text."'); " .
" INSERT INTO exp_ws_gk_state (WGS_STATE, WGS_TYPE, WGS_WGT_RID) ".
" VALUES('".$state."', ".$course_type.", LAST_INSERT_ID()); ".
"COMMIT;";
$mysql_query($sql);
$sql = "SELECT WGS_WGT_RID id FROM exp_ws_gk_text WHERE WGS_RID = ".mysql_insert_id();
$result = mysql_query($sql);
$r = mysql_fetch_array($result, MYSQL_ASSOC);
echo json_encode(array(
'id' => $r["id"],
'prg_code' => $prg_code,
'state' => $state,
'type' => $type,
'text' => $text
));
A delete:
DELETE a, b FROM exp_ws_gk_text a
JOIN exp_ws_gk_state b ON a.WGT_RID = b.wgs_wgt_rid
WHERE a.WGT_RID = :id
$sql = "UPDATE exp_ws_gk_text a, exp_ws_gk_state b
SET a.WGT_PRG_CODE = ".$prg_code.", a.WGT_TEXT = ".$text.", b.WGS_STATE = ".$state.", b.WGS_TYPE = ".$crs_type."
WHERE
a.WGT_RID = ".$id." AND a.WGT_RID = b.wgs_wgt_rid";
I have an UPDATE query and using Ajax, I wanted to know if any value is empty can I only update the values that not empty in the database. I don't know if this is possible to have a if statement or something to check to skip the empty values. I know I can just add another form element but just wanted to know if there was another solution.
Only if the data is POST from front end form. If data not POST don't update this Title = '.$title .',
$id = $_POST['id'];
$title = "";
$description = $_POST['Description'];
$date = $_POST['Date'];
$query = 'UPDATE user SET
`id` = '.$id.',
`Title` = '.$title .',
`Description` = '.$description.',
`Date` = '.$date =.'
WHERE `id` = '.$id;
$result = mysql_query($query) or die("<b>A fatal MySQL error occured</b>.<br />Query: ".$query."<br />Error: (".mysql_errno().") ".mysql_error());
Update: This is what worked for me. Thanks Karim Daraf
$query = " UPDATE user SET
Title = Coalesce($title,Title ) etc...
Try it with Coalesce .
$query = " UPDATE user
SET
`Title` = CASE WHEN `Title`='' or `Title` IS NULL THEN '$title' END,
`Description` = CASE WHEN `Description`='' Or `Description` IS NULL THEN '$description' END,
`Date` = CASE WHEN `Date`='' Or Date` IS NULL THEN '$date' END
WHERE `id` = '".$id."' ";
or :
$query = " UPDATE user
SET
`id` = Coalesce('$id''".$id."' , NULLIF(`id`,'')),
`Title` = Coalesce('$title''".$title."',NULLIF(`Title`,'') ) ,
`Description` = Coalesce('$description''".$description."' , NULLIF(`Description`,'') ) ,
`Date` = Coalesce('$date''".$date."',NULLIF(`Date`,''))
WHERE `id` = '$id''".$id."' ";
$query = 'UPDATE user SET
`id` = '.$id.',
`Title` = COALESCE(NULLIF("'.$title.'", ""),`Title`),
`Description` = "'.$description.'",
`Date` = "'.$date.'"
WHERE `id` = "'.$id.'"';
Not sure to understand: you have data and want to update, but only if some fied in the DB are empty?
In the case perfom only a where:
$query = 'UPDATE user SET
`id` = '.$id.',
`Title` = '.$title .',
`Description` = '.$description.',
`Date` = '.$date =.'
WHERE `id` = '.$id.' AND Title = '';
for example
