I'm trying to understand functions. I created a function and i want to call it multiple times. First I do a SQL query, save it in an array and convert it to seconds. The next thing is do a new SQL query (which does his job perfectly fine). When I try to convert this to seconds it goes wrong, I get this error:
Cannot redeclare myfunction() (previously declared in C:\xampp\htdocs\webpagina met input - kopie\try.php:103) in C:\xampp\htdocs\webpagina met input - kopie\try.php on line 103.
Can anyone help?

You call to convertArrayToMHS twice, every call you declare myfunction.
Put myFunction outside of convertArrayToMHS.

I'm working on a school project, and I'm currently working on a form.
I'm trying to insert the last inserted row from a table in my database into a session, so I can reuse the info when they want to go back to the form to adapt something.
So the data is being inserted into the database, but when I try to put the variable $insertedGegvens into a session, it returns null, and I don't understand why.
I currently have this:
PDO:
public function selectById($id) {
$sql = "SELECT * FROM `gegevens` WHERE `id` = :id";
$stmt = $this->pdo->prepare($sql);
$stmt->bindValue(':id', $id);
$stmt->execute();
}
public function insert($data) {
$errors = $this->validate( $data );
if (empty($errors)) {
$sql = "INSERT INTO `gegevens`
(`naam`, `gemeente`, `postcode`, `adres`,
`huisnr`, `email`, `tel`)
VALUES (:naam, :gemeente, :postcode, :adres,
:huisnr, :email, :tel)";
$stmt = $this->pdo->prepare($sql);
$stmt->bindValue(':naam', $data['naam']);
$stmt->bindValue(':gemeente', $data['gemeente']);
$stmt->bindValue(':postcode', $data['postcode']);
$stmt->bindValue(':adres', $data['adres']);
$stmt->bindValue(':huisnr', $data['huisnr']);
$stmt->bindValue(':email', $data['email']);
$stmt->bindValue(':tel', $data['tel']);
if ($stmt->execute()) {
return $this->selectById($this->pdo->lastInsertId()); //insert returns last row inserted through function selectById
}
}
return false;
}
public function validate( $data ){
$errors = [];
if (!isset($data['naam'])) {
$errors['naam'] = 'Gelieve een naam in te vullen';
}
if (!isset($data['gemeente'])) {
$errors['gemeente'] = 'Gelieve een gemeente in te vullen';
}
if (!isset($data['postcode'])) {
$errors['postcode'] = 'Gelieve een postcode in te vullen';
}
if (empty($data['adres']) ){
$errors['adres'] = 'Gelieve een adres in te vullen';
}
if (empty($data['huisnr']) ){
$errors['huisnr'] = 'Gelieve een huisnummer in te vullen';
}
if (empty($data['email']) ){
$errors['email'] = 'Gelieve een email in te vullen';
}
if (empty($data['tel']) ){
$errors['tel'] = 'Gelieve een telefoonnummer in te vullen';
}
return $errors;
}
if($_POST['action'] == 'toCheckout'){
$insertedGegevens = $this->orderDAO->insert($_POST);
//trying to insert the info it just inserted into a SESSION['user'] so I can reuse this info when user returns to form
$_SESSION['user'] = array();
$_SESSION['user'] = $insertedGegevens;
//$_SESSION['user'] returns null
if (!$insertedGegevens) {
$error = $this->orderDAO->validate($_POST);
$this->set('errors', $error);
}
$_SESSION['user'] = array();
$_SESSION['user'] = $insertedGegevens;
header('Location: index.php?page=checkout');

I have the next problem doing a json to read in Andorid
(the credentials are hidden but connection going good in others files)
class reportes
{
var $parametro;
var $conexion;
function __construct(){
$host = "IP"; $DBName = "DbName";
$usuario="user"; $contrasena="pass";
$driver = "DRIVER={iSeries Access ODBC Driver};
SYSTEM=$host;Uid=$usuario;
Pwd=$contrasena;Client_CSet=UTF-8;";
$this->conexion = odbc_connect($driver, $usuario, $contrasena);
}
function consulta($parametro){
$query=
"SELECT OHSNME,OHTOT$,OHREPÑ
FROM MYDB.SANFPRD.FOMHDR
WHERE OHORDÑ= $parametro ";
echo $query."<br><br>";
if ($this->conexion == 0) {echo "Ha fallado la conexion a la BBDD </br>";}
else{
$datos = array();
$result=odbc_exec($this->conexion,$query);
while($row = odbc_fetch_object($result)){
$datos[]= $row;
}
echo json_encode($datos);
}
}//Fin funcion consulta()
}//Fin de la clase
$consultar = new reportes();
$nota_venta = $_REQUEST['parametro'];
$consultar->consulta($nota_venta);
the response JSON that i get is:
SELECT OHSNME,OHTOT$,OHREPÑ FROM DELLORTO.SANFPRD.FOMHDR WHERE OHORDÑ= 366
[{"OHSNME":"E.C. GM. ","OHTOT$":"1861.00",null:" A07"}]
you can see that OHORDÑ is probably the problem with the 'Ñ'
but this table are part a productive database and i can't update
Solution #1, alias the column name to a name without non-ascii characters:
$query=
"SELECT OHSNME,OHTOT$,OHREPÑ AS OHREPN
FROM MYDB.SANFPRD.FOMHDR
WHERE OHORDÑ= $parametro ";
Solution #2, manually serialize using utf8_encode():
$result=odbc_exec($this->conexion,$query);
while($row = odbc_fetch_object($result)){
$_row_fix = array();
foreach ($row as $field => $val) {
$_row_fix[utf8_encode($field)] = utf8_encode($val);
}
$datos[]= $_row_fix;
}

This script really works and the output is here:
http://sitoxte.com/test%20mercato/array.php
But what I want to do is put this data to MySQL tabs, I need some help because I want to store the data each minute.
So i Try:
json-to-mysql
but I think that array in xml variable is not adeguate.
I want create a for cicle
and create 69 table like this:
table 1 eur/usd
id - Bid - Ask - High - Low - Direction - Last - timestamp
1
2
3
4...
and so on
refresh mode is simple and I do in this way whit javascript:
<script>
setInterval(function () {}, 3000);
var myVar=setInterval(function(){myTimer()},10000);
function myTimer()
{
var d = new Date();
document.getElementById("demo").innerHTML = d.toLocaleTimeString();
location.reload();
}
</script>
connetion is simple too and is like this:
//Host:
$localhost="******";
//database
$mioblog=*******;
//Nome utente:
$username=********;
//Password:
$password=*******;
// connessione a MySQL con l'estensione MySQLi
$mysqli = new mysqli("$localhost", "$username", "$password", $mioblog);
// verifica dell'avvenuta connessione
if (mysqli_connect_errno()) {
// notifica in caso di errore
echo "Errore in connessione al DBMS: ".mysqli_connect_error();
// interruzione delle esecuzioni i caso di errore
exit();
}
else
{
// notifica in caso di connessione attiva
echo "Connessione avvenuta con successo";
}
This depends on what you're using for your database, but assuming PDO, something like the below. If you need more details then look up a MySQL tutorial, but hopefully this gets you started and shows you how to traverse the XML.
foreach($xml->Rate as $rate) {
$query = "INSERT INTO tblrate (time, symbol, bid) VALUES (NOW(), :symbol, :bid)";
$query = $pdo->prepare($query);
$query->execute(array(
':symbol' => $rate->#attributes['Symbol'],
':bid' => $rate->Bid;
));
}
edit: If you only need one currency, something like this should work
foreach($xml->Rate as $rate) {
if($rate->#attributes['Symbol'] == 'EURUSD') {
$query = "INSERT INTO tblrate (time, bid) VALUES (NOW(), :bid)";
$query = $pdo->prepare($query);
$query->execute(array(
':bid' => $rate->Bid;
));
}
}
My friend Biagio help me to write code:
foreach($xml->children() as $xml_child){
$Symbol = $xml_child['Symbol'];
$Bid = $xml_child->Bid;
$Ask = $xml_child->Ask;
$High = $xml_child->High;
$Low = $xml_child->Low;
$Direction = $xml_child->Direction;
$Last = $xml_child->Last;
echo('$Symbol = '.$Symbol.'<br>');
echo('$Bid = '.$Bid.'<br>');
}

I want to browse data from my postgre database with a "foreach". So I made my request like that :
$conn_string = "host=localhost port=5432 dbname=test_postgre user=postgres password='1234'";
$dbconn = pg_connect($conn_string);
$sql = "SELECT id_traitement FROM public.traitement WHERE id_essai='.$id_essai.';";
$res = pg_query($sql) or die("Pb avec la requete: $sql");
$data = pg_fetch_all($res);
And I get my values with "pg_fetch_all".
After that, I'm looking for compare the data in my database (get with the request) and the data in my web page. So I created this loop :
foreach($array as $ligne_web)
{
foreach($data['id_traitement'] as $ligne_base)
{
if(($ligne_web[0] == $ligne_base) and ($flag))
{
//update de la ligne
update_traitement($id_traitement,$traitement,$code_traitement,$id_essai);
$flag2 = false;
break 1;
}
}
if(($flag) and ($flag2))
{
insert_traitement($id_traitement,$traitement,$code_traitement,$id_essai);
}
}
When I try to run it, firebug tells me : Invalid argument supplied for foreach(). So I don't know how to browse the rows in the database. Certainly my problem is in my foreach, but I don't find what's wrong.
Help please !
It seems your second foreach needs to be '$data' instead of $data['id_traitement']
So your code need to changed to ,
foreach($arr as $ligne_web)
{
foreach($data as $ligne_base) // <-- Here is the correction
{
if(($ligne_web[0] == $ligne_base) and ($flag))
{
------ REST of your Codes ------
Ok, I found an answer. Instead of an array $data from my database, and directly after the request, I created a new array.
Here is my code :
$conn_string = "host=localhost port=5432 dbname=test_postgre user=postgres password='1234'";
$dbconn = pg_connect($conn_string);
$sql = "SELECT id_traitement FROM public.traitement WHERE id_essai='.$id_essai.';";
$res = pg_query($sql) or die("Pb avec la requete: $sql");
$tableau_database_final = array();
while ($data = pg_fetch_all($res)) //Here is my array
{
$tableau_database = array('id_traitement'=>$data['id_traitement']);
array_push($tableau_database_final,$tableau_database);
}
$flag2 = true;
foreach($array as $ligne_web)
{
foreach($tableau_database_final as $ligne_base)
{
echo ($ligne_web[0]);
echo ($ligne_base);
if(($ligne_web[0] == $ligne_base)) //Si il existe une ligne ayant déjà le même id traitement
{
//update de la ligne
update_traitement($id_traitement,$traitement,$code_traitement,$id_essai);
$flag2 = false;
break 1;
}
}
if(($flag) && ($flag2))
{
//insert_traitement($id_traitement,$traitement,$code_traitement,$id_essai);
}
}
I have an webpage on which i want to display 2 separate tables with content from the same database. How do i run separate functions on a webpage and display 2 different results?
The code i have so far:
the second query that i want to run is in it as query2, but this doesn`t work....

$resultaat = ""; // hierin wordt het resultaat van de query opgeslagen
if (!$db = mysql_connect($server, $user, $wachtwoord)){ // probeert de verbinding te maken
$melding = "<h2>Verbinding maken met databaseserver is mislukt!</h2>";
}
else{
$melding = "<h2>Verbinding maken met databaseserver is tot stand gebracht!</h2>";
if(!mysql_select_db($database)){ // open de gewenste database

First problem, stop using mysql_ functions family... this kind of function was deprecated and will stop work soon or just don't run appropriately.
You should change to PDO family functions try this:
$dbh = new PDO('mysql:host=localhost;dbname=kse001_h5mh', '776', '776');
$query1 = $dbh->query("SELECT beschrijving FROM supermarkt WHERE soort = 'komkommertest'");
$query1->fetchAll(); // bring the result
$query2 = $dbh->query("SELECT beschrijving FROM supermarkt WHERE soort = 'hamburger'");
$query2->fetchAll(); // bring the result
This should work.
You can run 2 process of your script using the pcntl-fork function.
You can also try to use ob_flush function to send the output buffer between your 2 database requests.
In your case, I think it's a better option to load data in AJAX if it's possible.
