PHP Magento API catalog_product.info not working when running through a list

I am trying to create a magento API to get the pricing of each item. I have a table with all the SKU's i need to get info for. i ran the following for one item and it worked
$client = new SoapClient('http://www.mysite.com/api/soap/?wsdl');
$session = $client->login('user', 'pass');
$productId = 'ABC';
$att = array("visibility","sku","special_price", "price");
$arguments = array( $productId, NULL, $att);
$result = $client->call($session, 'catalog_product.info', $arguments);
echo $result['visibility'].",".$result['sku'].",".$result['special_price'].",".$result['price'];
the above code worked fine.
then i tested another code to make sure that my code to query the database and loop through each sku works
$getskus = "SELECT sku FROM items;";
$skus = mysqli_query($con, $getskus);
while($row = mysqli_fetch_array($skus))
{
$productId = $row['sku'];
echo $productId."<br>";
}
The above code works fine. My issue is when i combine the 2 i get a blank screen.
$client = new SoapClient('http://www.mysite.com/api/soap/?wsdl');
$session = $client->login('user', 'pass');
$getskus = "SELECT sku FROM items;";
$skus = mysqli_query($con, $getskus);
while($row = mysqli_fetch_array($skus))
{
$productId = $row['sku'];
$att = array("visibility","sku","special_price", "price");
$arguments = array( $productId, NULL, $att);
$result = $client->call($session, 'catalog_product.info', $arguments);
echo $result['visibility'].",".$result['sku'].",".$result['special_price'].",".$result['price'];
}
i get nothing. Any ideas?
update: if $row['sku'] = '9005' will magento think its a product id instead of a SKU?
This line:
$result = $client->call($session, 'catalog_product.info', $arguments);
This can't accept $arguments as the third param. Instead:
$result = $client->call($session, 'catalog_product.info', $row['sku'], null, $att, 'sku');
NB: not sure if 'null' (4th param) is a valid argument for store view. To be safe, replace with the correct store view (default, in most cases).

PDO row doesn't exist?

Below is my code:
<?php
$url = $_GET['url'];
$wordlist = array("Www.", "Http://", "Http://www.");
foreach ($wordlist as &$word) {
$word = '/\b' . preg_quote($word, '/') . '\b/';
}
$url = preg_replace($wordlist, '', $url);
?>
<?php
$oDB = new PDO('mysql:dbname=mcnsaoia_onsafe;host=localhost;charset=utf8', 'mcnsaoia_xx', 'PASSWORD');
$hStmt=$oDB->prepare("SELECT * FROM users WHERE hjemmside = :hjemmside AND godkendt=ja");
$hStmt->execute(array('hjemmside' => $url));
if( $row = $hStmt->fetch() ){
echo "EXIST";
}else{
echo "NOT EXIST";
}
?>
My problem is that it says NOT EXIST, because I know that there is a row which should be found with the following query:
SELECT * FROM users WHERE hjemmside = :hjemmside AND godkendt=ja
So why does it say not exist? I have absolutely no idea :(
Instead of
$hStmt=$oDB->prepare("SELECT * FROM users WHERE hjemmside = :hjemmside
AND godkendt=ja");
try
$hStmt=$oDB->prepare("SELECT * FROM users WHERE hjemmside = :hjemmside
AND godkendt='ja'");
The left is most likely a column and the right side is a string? I don't speak your language, but this is the first thing coming to my mind.
You should surround with quotes your not integer variable in your query
AND godkendt='ja'
Or maybe let pdo deal with it
$hStmt=$oDB->prepare("SELECT * FROM users WHERE hjemmside = :hjemmside AND godkendt = :ja");
$hStmt->execute(array(':hjemmside' => $url, ':ja' => 'ja'));
//^ i added : for placeholder here, you missed it
I would also rather check if rows are returned
if($hStmt->$eowVount() > 0){
$row = $hStmt->fetch()
echo "EXIST";
}else{
echo "NOT EXIST";
}

How to output JSON from recordset in Dreamweaver with minimal manual code? [duplicate]

I have a basic MySQL database table People with 3 columns (ID, Name, Distance)
I am trying to output this with PHP as a JSON so my web app can pick it up. I tried using the solution from another answer:
$sth = mysql_query($con,"SELECT * FROM People");
$rows = array();
while($r = mysql_fetch_assoc($sth)) {
$rows[] = $r;
}
print json_encode($rows);
However I am just returning a blank array of [].
Update: Changed to mysqli and added dumps:
$sth = mysqli_query("SELECT * FROM Events",$con);
$rows = array();
var_dump($sth);
while($r = mysqli_fetch_assoc($sth)) {
var_dump($rows);
$rows[] = $r;
}
print json_encode($rows);
Returns:
NULL []
Swap your query and connection in the mysql_query-statement:
$sth = mysql_query("SELECT * FROM People", $con);
Besides that, the mysql-library is deprecated. If you're writing new code consider using mysqli_ or PDO.
Why no mysql_connect ?
var_dump($sth); // check the return of mysql_query()
var_dump($rows); // check the array of mysql_fetch_assoc result
I would check if your query is returning any rows first.
<?php
$rows = array();
array_push($rows, array("name" => "John"));
array_push($rows, array("name" => "Jack"));
array_push($rows, array("name" => "Peter"));
print json_encode($rows);
?>
Produces this output.
[{"name":"John"},{"name":"Jack"},{"name":"Peter"}]
Solved using a combination of answer to get:
$sth = mysqli_query($con,"SELECT * FROM Events");
$datarray = array();
while($row = mysqli_fetch_assoc($sth)) {
$datarray[] = $row;
}
print_r(json_encode($datarray));

How to get particular column in zend using Left join

I am new to zend framework,
Following is the plain mysql query which takes particular column from table,
SELECT jobs_users.id,jobs_users.first_name from jobs_users left join friends on jobs_users.id=friends.friend_id where friends.member_id=29
I tried with zend to implement the above query like below,
public function getFriendsProfileList($id){
$db = Zend_Db_Table::getDefaultAdapter();
$select = $db->select();
$select->from('jobs_users')
->joinLeft(
'friends',
'jobs_users.id=friends.friend_id',
array('jobs_users.id','jobs_users.first_name','jobs_users.last_name','jobs_users.photo')
)
->where("friends.member_id = ?", $id);
$result = $db->fetchAll($select);
return $result;
}
Here i got result with all column name , not with exact column name which i have given in query.
Kindly help me on this.
Use this instead:
$select->from('jobs_users', array('jobs_users.id','jobs_users.first_name','jobs_users.last_name','jobs_users.photo'))
->joinLeft('friends', 'jobs_users.id=friends.friend_id')
->where("friends.member_id = ?", '20');
You may also try this:
$select = $db->select();
$select->setIntegrityCheck(false);
$select->joinLeft('jobs_users','',array('jobs_users.id','jobs_users.first_name','jobs_users.last_name','jobs_users.photo'));
$select->joinLeft('friends','jobs_users.id=friends.friend_id', array());
$select->where("friends.member_id = ?", $id);
$result = $db->fetchAll($select);
return $result;
