Aide à enchaîner une requête?

je me bats pour obtenir la syntaxe correcte pour ma requête. La requête est:

$query = "SELECT product_sku FROM #__virtuemart_products WHERE created_on <= NOW();";

J'ai actuellement:

$query
    ->select($db->quoteName(array('product_sku')))
    ->from($db->quoteName('#__virtuemart_products'))
    ->where($db->quoteName('created_on') . ' >=NOW();)
    ->order('ordering ASC');

Mais cela me donne une erreur de 500 serveur.

Des idées?

Cordialement Donna

Edit: C’est pour que j’utilise correctement l’API Joomla dans mon php. Edit 2: Le code complet est ci-dessous:

<?php

//display errors
error_reporting(E_ALL);
ini_set("display_errors", 1);

//init Joomla Framework 
define('_JEXEC', 1); 
define('JPATH_BASE', dirname(__FILE__).'/');
define('JPATH_COMPONENT',dirname(__FILE__).'/');
define('DS', DIRECTORY_SEPARATOR); 

//echo JPATH_BASE;

require_once (JPATH_BASE .DS. 'includes' .DS. 'defines.php'); 
require_once (JPATH_BASE .DS. 'includes' .DS. 'framework.php');

// Start database stuff
$db = JFactory::getDbo();

//Select records that were created today
$query = "SELECT product_sku FROM #__virtuemart_products WHERE created_on >= NOW();";


//The query below needs fixing
/*$query->select($db->quoteName(array('product_sku')))
    ->from($db->quoteName('#__virtuemart_products'))
    ->where('created_on >= NOW()')
    ->order('ordering ASC');*/

$db->setQuery($query);

$result = $db->loadObjectList();
$result = $db->execute();
$my_count = $db->getNumRows($result); 
//echo($my_count);

//Check if any records are returned, if none then end
if ($my_count == 0){
echo "No records found";
exit;
}

if (!$result) die('Couldn\'t fetch records');
$headers = $result -> fetch_fields();
foreach($headers as $header) {
$head[] = $header->name;
}


// Check if the file already exists, if so delete it

$filename = '/home/website/public_html/temp_cron/new.csv';

if (file_exists($filename)) {
    array_map('unlink', glob($filename));
    //echo "The file $filename has been deleted";
}

$fp = fopen($filename, 'x');
if ($fp && $result) {
fputcsv($fp, array_values($head)); 
while ($row = $result->fetch_array(MYSQLI_NUM)) {
    fputcsv($fp, array_values($row));
}

}

Essayez ce code -

// Start database stuff
$db = JFactory::getDbo();

// Create a new query object.
$query = $db->getQuery(true); //-> you are missing this

//Select records that were created today
$query->select($db->quoteName(array('product_sku')))
    ->from($db->quoteName('#__virtuemart_products'))
    ->where($db->quoteName('created_on') . ' >= NOW()')
    ->order('ordering ASC');

$db->setQuery($query);

$result = $db->loadObjectList();
$result = $db->execute();
$my_count = $db->getNumRows($result);

Aussi s'il vous plaît supprimer

$result = $db->execute();

Ce n'est pas nécessaire ici.

Quelques liens utiles

  1. Sélection de données à l'aide de JDatabase
  2. Insertion, mise à jour et suppression de données à l'aide de JDatabase

J'espère que ça marchera pour toi :)

Ce qui suit est le bon ordre:

$db->setQuery($query);
$db->execute();
$my_count = $db->getNumRows(); 
$result = $db->loadObjectList();

C'est intéressant, car pour obtenir les résultats uniquement, ce code suffit:

$db->setQuery($query);
$result = $db->loadObjectList();

Obtenir une erreur 500 à cause de cela est ridicule. Je veux dire que j'ai une page d'erreur nginx, donc l'exception n'a pas été capturée par joomla ...
