hello, please where is the problem... this is my php code:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>Výsledky</title>
</head>

<body>
<h2>Výsledky </h2>
<?php
$mysqlhostitel="localhost";
$mysqluzivatel="ODBC";
$mysqlheslo="";
$mysqldb="test_hlasovani";

//pripojime se k db

$link = mysql_connect($mysqlhostitel, $mysqluzivatel, $mysqlheslo) or die ("Error: ".mysql_error());
mysql_select_db($mysqldb) or die("Could not select database: ".mysql_error());

//pokud jsou k dispozici data formulare, zpracujeme je a ulozime
function array_item($ar, $key){
if (array_key_exists($key,$ar))return($ar[$key]);
return('');}
$potvrzeni = array_item($_POST, 'potvrzeni');
$hlasovani = intval(array_item($_POST, 'hlasovani'));

if($potvrzeni=="Odeslat"){
if($hlasovani >=1 && $hlasovani <=6){
	mysql_querry("INSERT INTO volenyjazyk (volba) VALUES($hlasovani)");
}
else{
	echo"<p>Tento jazyk neni správny.Prosím volte znovu. Zpět na <a href=\"01hlasovani.html\">dotazník</a>.</p></body></html>\n";
	exit();
}
}

//zobrazíme vysledky
echo "<p><b>Jaký programovací jazyk nejraději používáte pro tvorbu MySQL aplikací?</b></p>\n";

//celkový počet hlasů
$vysledek = mysql_querry("SELECT COUNT(volba) FROM volenyjazyk");
$pocethlasu = mysql_result($vysledek, 0,0);

//procenta
if($pocethlasu == 0){
echo "<p>Nikdo zatim nehlasoval</p>\n";
}
else{
echo"<p>$pocethlasu lidí hlasovalo:</p>\n";
$textvolby = array (1 => "C/C++", "Java", "Perl", "PHP", "ASP", "Jinej");
print ("<p><table>\n");
for($i=1; $i<=6; $i++){
	$vysledek = mysql_query("SELECT COUNT(volba) FROM volenyjazyk " .
	"WHERE volba = $i");
	$volba = mysql_result($vysledek, 0,0);
	$procent = round($volba/$pocethlasu*10000)/100;
	print("<tr><td>$textvolby[$i]:</td>");
	print("<td>$procent %</td></tr>\n");
}
print("</table></p>\n");
}

?>
</body>
</html>

 

 

but the result is:

Výsledky

=1 && $hlasovani <=6){ mysql_querry("INSERT INTO volenyjazyk (volba) VALUES($hlasovani)"); } else{ echo"

 

Tento jazyk neni správny.Prosím volte znovu. Zpět na dotazník.

\n"; exit(); } } //zobrazíme vysledky echo "

 

Jaký programovací jazyk nejraději používáte pro tvorbu MySQL aplikací?

\n"; //celkový počet hlasů $vysledek = mysql_querry("SELECT COUNT(volba) FROM volenyjazyk"); $pocethlasu = mysql_result($vysledek, 0,0); //procenta if($pocethlasu == 0){ echo "

 

Nikdo zatim nehlasoval

\n"; } else{ echo"

 

$pocethlasu lidí hlasovalo:

\n"; $textvolby = array (1 => "C/C++", "Java", "Perl", "PHP", "ASP", "Jinej"); print ("

 

\n"); for($i=1; $i<=6; $i++){ $vysledek = mysql_query("SELECT COUNT(volba) FROM volenyjazyk " . "WHERE volba = $i"); $volba = mysql_result($vysledek, 0,0); $procent = round($volba/$pocethlasu*10000)/100; print(""); print("\n"); } print("

$textvolby[$i]: $procent %

\n"); } ?>

 

why?

 

 

if i tryied connect like this:

 

$connection =@mysql(....);

if ($connection == FALSE){

echo .... Not possible ...

exit();

}

 

but it PHP could connect to DB so it was detected like FALSE, and even if there was exit(); on the site continous the php code .. :-(

 

what is wrong?

thanks

Hi,

I have tried it. But the result is still the same . even no error report.  I guess that the php wont work properly.

Coz it cant connect to DB via:

 

$mysqlhostitel="localhost";
$mysqluzivatel="root";
$mysqlheslo="pass";
$connection =@mysql_connect($mysqlhostitel, $mysqluzivatel, $mysqlheslo);
if($connection == FALSE){ ....

- it is always false.

 

 

but how i have install php properly with all extensions. and the phpMyadmin works fine with DB. I have W7 and the ipV6 disabled.

	print("<td>$procent %</td></tr>\n");
}
print("</table></p>\n");
}

?>
</body>
