Trying To Find A Match In Database But Data Is Stored In Unicode

[timski72]

Hi Guys,

 

 

I have a test database with a record in it where the field "requested" is set to "η μητερa" (Greek characters, i.e. unicode)

 

If I perform the following query in phpMyAdmin "SELECT syllabilized FROM transliterated WHERE requested = η μητερa" I get the expected result.

 

This query doesn't seem to be working within my php script however. I am not sure if it is due to my php code (which is very newby) or a problem with de/encoding unicode.

 

Here is the my scripts (truncated) with the $input hardcoded for testing. I've tested with $_POST['greek'] posting from the website and hardcoded when debugging in phpDesigner but neither is working. I get a result so it goes into the else statement but the output is blank.

 

 

 

<?php
ini_set('default_charset', 'UTF-8');
mb_internal_encoding("UTF-8");

// $input = $_POST['greek'];
$input = "η μητερa";
$connection = mysqli_connect($host, $user, $passwd, $dbname) or die(mysqli_error());
$query = "SELECT syllabilized FROM transliterated WHERE requested = '$input'";
$result = mysqli_query($connection, $query) or die($query);


if (!$result) {
// NO CODE FOR THIS SECTION YET
}
else
{
$row = mysqli_fetch_row($result);
 $syllablized == $row[2];
 $input == $syllablized;
 echo $input;
}


?>

 

Here is the content and structure of the database.

requested generated syllabilized modified create edit

η μητερa ee meetehrah ee mee-teh-rah No 18/02/2010 16:45 19/02/2010 16:46

 

So I'm expecting the user to enter η μητερa and get ee mee-teh-rah back.

 

Any tips would be very welcome.

Thanks,

Tim.

After you make your database connection, add the following line of code and see if it corrects the problem -

 

mysqli_set_charset($connection, "utf8");

 

Also, $row[2] in the fetched $row array doesn't exist (unless you also altered your query for the post), since you are only selecting the syllabilized column. Try $row[0].

Thanks for you reply. I modified the code incorporating your suggestions as below. $syllabilized is still blank.

 

Tim.

 

<?php

ini_set('default_charset', 'UTF-8');

mb_internal_encoding("UTF-8");

 

// $input = $_POST['greek'];

$input = "η μητερa";

$connection = mysqli_connect($host, $user, $passwd, $dbname) or die(mysqli_error());

mysqli_set_charset($connection, "utf8");

$query = "SELECT syllabilized FROM transliterated WHERE requested = '$input'";

$result = mysqli_query($connection, $query) or die($query);

 

if (!$result) {

// NO CODE FOR THIS SECTION YET

}

else

{

$row = mysqli_fetch_row($result);

$syllablized == $row[0];

echo syllablized;

?>

$syllablized == $row[0];

 

Two == signs is a equal comparison operator. One = sign is an assignment operator.

Thank you so much. I wouldn't have spotted it. Sometimes you can't see the wood for the trees :-)

 

Works great now :-)
