public function getWorkers()
{
$db = JFactory::getDBO();
$orderid=$this->getTodayOrder();
$workersId=array();
foreach($orderid as $workers1)
{
$query2 = "SELECT * FROM #__orderassignment WHERE orderid='".$workers1."'";
$db->setQuery($query2);

if array is given then you need to access it like this
$workersId[]=$workers1['workers'];

Trying to get property of non-object in on line 20
class.php
class PostsData extends dbh {
public function fetchAllPosts() {
$sql = "SELECT * FROM post";
$stmt = $this->connect()->query($sql);
$stmt->execute([]);
$result = $stmt->fetchAll();
return $result;
} }
blog.php
$post_ = new PostsData;
$allposts = $post_->fetchAllPosts();
foreach ($allposts as $post) {
echo $post->post_title; //error

You are not checking if the result returned is null or not. The error would be generated if it is because there will be no property to access altogether.
Consider a print statement in FetchAllPosts function to check if you get any rows returned. That may help narrow down the scope of the error.

$stmt->execute(array($member_id));
$member = $stmt->fetch(PDO::FETCH_ASSOC);
$fund = $member-> sales_hold_fund;// line54
$sales_hold_fund = $fund + $amount;
I want to get the sales_hold_fund value from database and add the amount value to the sales_hold_fund.

}
Can anyone help please? Thank you..

Creating default object from empty value in PHP?

I am stuck. I have spent two days looking thru all the references I can find and I can’t figure out why this will not work! I get the error: "Creating default object from empty value." Bellow is my SQL statement and my parameters array.
$sql_insert = "
INSERT INTO vrm_vrd_submission_tbl (vrm_vrd_nmbr_id, vrm_vrd_sub_type_id, vrm_vrd_sub_date, vrm_vrd_min_form_date, vrm_vrd_sub_quantity, county_id, pers_emp_pre_id, election_general_info_id ,vrm_vrd_sub_submitter_name, vrm_vrd_compliance_rules_id)

$sql_parms=array(":vrm_vrd_nmbr_id"=>$vrm_vrd_nmbr_id, ":vrm_vrd_sub_type_id

":vrm_vrd_compliance_rules_id"=> $vrm_vrd_compliance_rules_id);
$ret_val=$db->db_bound_query($sql_insert, $sql_parms);
Method being called in my database class:
public function db_bound_query($qry_str, $parms_array){
$log = new error_log_class;
$db_conn = self::_connect();
if(!$exec_str= $db_conn->prepare($qry_str)){
$log->save_to_log($qry_str,__LINE__,__FILE__,"Failed to perpare.");
}
$val="";
foreach($parms_array as $parm ->$val){
$exec_str->bindParam($parm,$val);
}
$res=$exec_str->execute();
$results= $exec_str->fetchAll(PDO::FETCH_ASSOC);
}
EDIT:
I changed this method to the following as suggensted by #iamsleepy and #MrCode. But I am getting the error I was originally chasing which is "Invalid Parameter number".
public function db_bound_query($qry_str, $parms_array){
$log = new error_log_class;
$db_conn = self::_connect();
if(!$exec_str= $db_conn->prepare($qry_str)){
$log->save_to_log($qry_str,__LINE__,__FILE__,"Failed to perpare.");
}
$res=$exec_str->execute($parms_array );
$results= $exec_str->fetchAll(PDO::FETCH_ASSOC);
return $results;
}

You have a space at the end of this parameter name:
":pers_emp_pre_id "=>$data['pers_emp_pre_id']
^ here
Should be:
":pers_emp_pre_id"=>$data['pers_emp_pre_id']

check when PDO Fetch select statement returns null

I am a beginner with php and PDO and need help solving this error that I keep getting on this line of code
$category_name [$category["category_id"]] = $category["category"]; I continue to get, Notice: Undefined index: category. Also Undefined index: category_id. I dont have a clue as to why, could someone provide me with the correct way to do this. Here is my code. This one slightly different because it used in a while statement.
// get the item category names
$category_name = Array();
$query = 'SELECT * FROM category_2';
$categories_list = $db->prepare($query);
$categories_list->execute();
while ($category = $categories_list->fetchAll())
{
$category_name [$category["category_id"]] = $category["category"];
}

try this:
We will have single array in each time in loop in $category. You can access any database attributes in this array like this: $category['attribute_name']
while ($category = $categories_list->fetch(PDO::FETCH_ASSOC))
{
$category_name [$category["category_id"]] = $category["category"];
}
print_r($category_name);

You're probably looking for fetch(PDO:: FETCH_ASSOC) instead of fetchAll()

How can I convert this simple query to CakePHP? [duplicate]

converting simple query to cake query?
Actually I have 1 query but I am unable to convert it into CakePHP query format.
$result = "select
* from esl_userresults, esl_lyrics
where
esl_userresults.esl_songID = esl_lyrics.id
and esl_lyrics.song_name like '%".$esl_keyword."%'" ;
When I convert this query into CakePHP it gives an error like:
esl_userresults.esl_songID unknown column.

You can execute any query using:
<?php
function some_controller_name()
{
$query_to_execute = 'SELECT * .....';
$results = $this->ModelName->query($query_to_execute);
$this->set('results', $results);
}
?>
Hope this helps
