please excuse me for my bad english.
I'm trying to write a website similiar Facebook's chronics. I had testing it on localhost with xampp. There was it fine. After the upload of my documents on my webspace, I get the warning-message. My origin problem is, when I refresh my site the last message (who was save on mysql) will be write and save repeatedly.
Now I'm knowing what my problem is, the order from output and "header('Location: site.php');".
if I put the command before my output, than is the webside refreshing too often.
If I put an "@flush();" before my command, it's don't change something.
If I put an "exit();" after my command, my messages will do not show.
I do not understand, what is so differently between xampp localhost and mysql on webspace.
My code for the php-function to save is:
function saveMessage($mensch){
global $pdo;
$datum = date("Y.m.d",time());
$zeit = date("H:i:s",time());
$nachricht = $_POST['eigeneNachricht'];
$nachricht = preg_replace( '/[^a-z0-9ÄäÖöÜü.,;:-_ ]/i', '', $nachricht );
$speichern = $pdo->prepare("INSERT INTO nachrichtensammlung (Nickname, Datum, Zeit, Nachricht) VALUES (:mensch,:datum2,:zeit,:nachricht)");
$speichern->execute(array('mensch' => "$mensch", 'datum2' => $datum, 'zeit' => $zeit, 'nachricht' => "$nachricht"));
echo "$mensch hat am $datum, um $zeit geschrieben: <br> \n <b> $nachricht </b> <hr />";
header('Location: downloads.php');
exit();
}
My php-function to show my messages:
function showMessage($mensch){
global $pdo;
$anzahlEintrage = $pdo->prepare("SELECT * FROM nachrichtensammlung WHERE Nickname = '$mensch'");
$anzahlEintrage->execute(array("$mensch"));
$anzahl = $anzahlEintrage->rowCount();
$auslesen = "SELECT * FROM nachrichtensammlung WHERE Nickname = '$mensch'";
$row = $pdo->query($auslesen)->fetch();
$ergebnisse = $pdo->query("SELECT * FROM nachrichtensammlung WHERE Nickname = '$mensch'");
echo "(insgesamt $anzahl Nachrichten) <br > \n";
$i = 1;
while($reihe = $ergebnisse->fetch()){
echo "<artikel>";
echo "<avatarKlein> </avatarKlein>";
echo "<nachricht>";
echo "<i>[Nachricht $i]</i> Am ";
echo $reihe['Datum'];
echo " um ";
echo $reihe['zeit'];
echo "schrieb $mensch: <br> \n";
echo $reihe['Nachricht'];
echo "<hr /> ";
echo "</nachricht>";
echo "</artikel> <hr />";
$i++;
}
$pdo = null;
}
My php-functions are not in my html-script. It's in a own php-site.
I hope someone has an idea how I can solve my problem.
Who was branding my question like a dublicate? I did find all the other "answers" here, before I wrote my question. No "answer" is helping me.
Maybe I don't see the "answer", then write the answer too. It is impossible, to branding like dublicate, without one or two sentences. I thought in Germany are crazy people only.
