Retrieving Data

[2minutes2midnight]

I have a basic table where I am trying to retrieve records that are filtered by a form request. Here is the code I have...

$ps = $pdo->prepare("SELECT * FROM `Products` Where `Vendor` LIKE concat('%',?,'%');
$ps->execute(array($_POST['Vendor']));;
echo "post=" . $_POST['vendor']; ////Displays correct data from form request
$count = $ps->rowCount();
echo "Count=" . $count; ////Count = 0 although I know for a fact that there is 1 record that should be in there

////Used for display of records
foreach ($ps as $row){
echo $row, PHP_EOL . "xxx<br>";
}

Where is the incorrect code? I am new to php and pdo. Thank you in advance

I'm going to assume you're using mysql:

 

From the PHP.net page on rowCount (http://www.php.net/manual/en/pdostatement.rowcount.php):

 

For most databases, PDOStatement::rowCount() does not return the number of rows affected by a SELECT statement. Instead, use PDO::query() to issue a SELECT COUNT(*) statement with the same predicates as your intended SELECT statement, then use PDOStatement::fetchColumn() to retrieve the number of rows that will be returned. Your application can then perform the correct action.

 

 

This has been a known issue with rowCount for some time now.

Also, $_POST['Vendor'] os not the same as $_POST['vendor']
