Database not storing the Greek Characters correctly

Good afternoon one and all,

I've recently deployed a website on a remote server, and using the same mySQL creation script, created a database. Two of the fields need to display Greek Characters, and so their collation is set to greek_general_ci. This works fine on my local dev machine (which is the same as the set up on the server, probably a few security settings are different.) However...

I've gone to add some stuff to the data base, and all I'm getting in the data base is ????? instead of the greek character Unicode codes that I get on my local machine.

I've checked that the server has the collations on, and 开发者_开发百科the correct character sets. And I've googled for the answer, but alas I've had no success. I was wondering if it was something I could fix, or should I contact the server admin for them to have a look at it? As I don't want to mess around with the server settings, as there's a live website running off the same data base engine.

Many thanks in advance.

I've been asked to post the code here, so this is the code as it stands.

AddWord.html I've only added the form, as that's all that needs to be seen.

<form name="addwrd" action="addWord.php" method="post">
                        <label for="greek_word">Greek Word</label>
                        <input type="text" onkeyup="trans(this.id)" id="greek_word" name="GreekWord" size=30><br><br>                        
                        <label for="greek_definition">Greek Definition</label>  
                        <input type="text" onkeyup="trans(this.id)" id="greek_definition" name="GreekDefinition" size=30><br><br>
                        <label for="EnglishWord">English Word</label>
                        <input type="text" name="EnglishWord" size=30><br><br>
                        <label for="EnglishDefinition">English Word</label>
                        <input type="text" name="EnglishDefinition" size=30><br><br>
                        <label for="chapter">Chapter</label>
                        <input type="text" name="chapter" size=20><br><br>
                        <label for="section">Section</label>
                        <input type="text" name="section" size=20><br><br>
                        <label for="hint">Hint</label>
                        <input type="text" name="hint" size=50><br><br>
                        <input type="submit" name="addword" value="Submit">
                    </form>

AddWord.php

include_once( 'admin_dataHandler.php' );

$dataHandler = new DataConnection();

/** 
 * The variables we're getting back from the HTML form we've just filled
 * in.
 */
$greekWord = $_POST['GreekWord'];
$greekDef = $_POST['GreekDefinition'];
$englishWord = $_POST['EnglishWord'];
$englishDef = $_POST['EnglishDefinition'];
$chapter = $_POST['chapter'];
$section = $_POST['section'];
$hint = $_POST['hint'];

$dataHandler->addWord($greekWord, $greekDef, $englishWord, $englishDef, $chapter, $section, $hint);
// The header should redirect to the admin index.html page.

And this is the code from the data handler that adds the word to the data base.

function addWord($grkWrd, $grkDef, $engWord, $engDef, $chptr, $sects, $hint){
            $sql = "INSERT INTO word (GreekWord, GreekDefinition, EnglishWord, EnglishDefinition, Chapter, Sections,Hint) values (:grkWrd,:grkDef,:engWrd,:engDef,:chptr,:sctn,:hnt)";
            $stmt = $this->dataHandler->prepare( $sql );
            $stmt->bindParam(':grkWrd', $grkWrd , PDO::PARAM_STR, 45);
            $stmt->bindParam(':grkDef', $grkDef , PDO::PARAM_STR, 45);
            $stmt->bindParam(':engWrd', $engWord , PDO::PARAM_STR, 45);
            $stmt->bindParam(':engDef', $engDef , PDO::PARAM_STR, 45);
            $stmt->bindParam(':chptr', $chptr , PDO::PARAM_STR, 45);
            $stmt->bindParam(':sctn', $sects , PDO::PARAM_STR, 45);
            $stmt->bindParam(':hnt', $hint , PDO::PARAM_STR, 45);
            $stmt->execute();
        }

I hope this provides further information, my apologies for not posting the code the first time out.

Thanks for taking the time to look at this.

I think that all of those Greek characters should be contained within UTF8 and that'd you'd save yourself some grief by setting everything up to use UTF8.

You talked about Greek character unicode codes but the greek collation isn't unicode, it's ISO 8859-7 (see Character Sets and Collations That MySQL Supports)

I wrote an article on character set problems with PHP/MySQL just a few days ago which I think could have some relevant information. How to Avoid Character Encoding Problems in PHP

I really doubt it's the database that's the problem. You should double check your code, or post it here, because that's by far the most likely culprit.
