somehow i must make a mistake somewhere and can't seem to find the correct solution, must be doing something wrong. I want to update my Azure SQL table called Celebrity from a PHP page and it doesn't update. Can you pls help me or tell me what i am doing wrong
<?php
try {
$conn = new PDO( "sqlsrv:Server= $host ; Database = $db ", $user, $pwd);
$conn->setAttribute( PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION );
}
catch(Exception $e){
die(var_dump($e));
}
if(!empty($_POST)) {
try {
$FirstName = $_POST['FirstName'];
$LastName = $_POST['LastName'];
$id = $_POST['id_celebrity'];
$sql_update = "UPDATE
Celebrity
SET
(FirstName, LastName)
VALUES
(?,?)
WHERE
id_celebrity='$id'";
$stmt = $conn->prepare($sql_update);
$stmt->bindValue(1, $FirstName);
$stmt->bindValue(2, $LastName);
$stmt->execute();
}
catch(Exception $e) {
die(var_dump($e));
}
echo "Celebrity Updated in DB!";
}
?>
Here is the instruction in use and this is what i get back from the AZURE server:
object(PDOException)#3 (8) { ["message":protected]=> string(97) "SQLSTATE[42000]: [Microsoft][SQL Server Native Client 11.0][SQL Server]Incorrect syntax near '('." ["string":"Exception":private]=> string(0) "" ["code":protected]=> string(5) "42000" ["file":protected]=> string(62) "D:\home\site\wwwroot\CelebrityOverview\CelebrityEditResult.php" ["line":protected]=> int(57) ["trace":"Exception":private]=> array(1) { [0]=> array(6) { ["file"]=> string(62) "D:\home\site\wwwroot\CelebrityOverview\CelebrityEditResult.php" ["line"]=> int(57) ["function"]=> string(7) "execute" ["class"]=> string(12) "PDOStatement" ["type"]=> string(2) "->" ["args"]=> array(0) { } } } ["previous":"Exception":private]=> NULL ["errorInfo"]=> array(3) { [0]=> string(5) "42000" [1]=> int(102) [2]=> string(80) "[Microsoft][SQL Server Native Client 11.0][SQL Server]Incorrect syntax near '('." } }
Try this instead:
$sql_update = "UPDATE Celebrity
SET FirstName = ?, LastName = ?
WHERE id_celebrity='$id'";
Assigning each column a value with a comma in between, UPDATE markup is not same as INSERT.
this is code i am trying to work with. i am checking number of total row in a table(how many people registered). my output don't have any error or so, i dont know what am i doing wrong. same thing was working yesterday. god knows what happened now
$query = "SELECT count(*) FROM team";
$result = $db->prepare($query);
$result->execute();
$number= $result->fetch();
print_r($number);
var_dump($result);
OUTPUT:
1
object(mysqli_stmt)#2 (10) { ["affected_rows"]=> int(-1) ["insert_id"]=> int(0) ["num_rows"]=> int(0) ["param_count"]=> int(0) ["field_count"]=> int(1) ["errno"]=> int(0) ["error"]=> string(0) "" ["error_list"]=> array(0) { } ["sqlstate"]=> string(5) "00000" ["id"]=> int(1) }
You could do the following:
$query = "SELECT count(1) FROM team";
if($stmt = $db->prepare($query)){
$stmt->execute();
$stmt->bind_result($number);
$stmt->fetch();
$stmt->free_result();
$stmt->close();
}
echo $number;
or
$query = "SELECT * FROM team";
if($stmt = $db->prepare($query)){
$stmt->execute();
$stmt->store_result();
$number = $stmt->num_rows;
$stmt->free_result();
$stmt->close();
}
echo $number;
I'm fairly new to PHP, and I'm working with mysqli, OOP and prepared statements.
My question is this:
I'm trying to pass an user(object) to an Insert_user(func) in my database(class).
I have 3 classes, 'logic', 'data' and 'index'. Index includes data and logic, and initiates
the connection and user.
In my function (insert_user), I'm using an array to pass user variables into, before
binding and executing my statement.
Hers is my code:
<?php
function insert_user($user) {
$query = "INSERT INTO user VALUES (?,?,?,?,?,?,?,?,?,?)";
$binding = 'issssiisss';
$variables = array( $user->user_id, $user->f_name, $user->l_name, $user->address, $user->city, $user->zipcode, $user->mobile_number, $user->mail, $user->pass_key, $user->pass_word);
$stmt = $this->mysqli->prepare($query);
$stmt->bind_param($binding,$variables[0],$variables[1],$variables[2],$variables[3],$variables[4],$variables[5],$variables[6],$variables[7],$variables[8],$variables[9]);
$stmt->execute();
}
?>
Here is my var_dump from browser:
object(user)#1 (10) { ["user_id"]=> int(1) ["f_name"]=> string(5) "pelle" ["l_name"]=> string(5) "kanin" ["address"]=> string(7) "vænget" ["city"]=> string(6) "aaaaaa" ["zipcode"]=> int(123) ["mobile_number"]=> int(123) ["mail"]=> string(4) "fedt" ["pass_key"]=> string(3) "ert" ["pass_word"]=> string(4) "erto" }
string(10) "issssiisss"
array(10) { [0]=> int(1) [1]=> string(5) "pelle" [2]=> string(5) "kanin" [3]=> string(7) "vænget" [4]=> string(6) "aaaaaa" [5]=> int(123) [6]=> int(123) [7]=> string(4) "fedt" [8]=> string(3) "ert" [9]=> string(4) "erto" }
object(mysqli_stmt)#4 (10) { ["affected_rows"]=> int(-1) ["insert_id"]=> int(0) ["num_rows"]=> int(0) ["param_count"]=> int(10) ["field_count"]=> int(0) ["errno"]=> int(0) ["error"]=> string(0) "" ["error_list"]=> array(0) { } ["sqlstate"]=> string(5) "00000" ["id"]=> int(1) }
What am i doing wrong!?
Thank you.
EDIT: The problem is inserting the data into the database. It simply doesn't work. When i execute no data is put in.
I think the problem lies with the $stmt->bind_param function, and inserting the data from the array.
param_count = 10 and field_count = 0!
EDIT !2!:
OK. So, it actually works! what i did wrong was specify a integer value in my user_id, i.e. when i created the user. My database uses AUTO.INCREMENT on that value, and therefore it didn't work..
Anyways, thanks for the answer. G'day!
Check if you have any errors when after each mysqli statement to isolate the error:
$stmt = $this->mysqli->prepare($query);
if ( false===$stmt ) {
die('prepare() failed: ' . htmlspecialchars($mysqli->error));
}
$stmtBindResult = $stmt->bind_param($binding,$variables[0],$variables[1],$variables[2],$variables[3],$variables[4],$variables[5],$variables[6],$variables[7],$variables[8],$variables[9]);
if ( false===$stmtBindResult ) {
die('bind_param() failed: ' . htmlspecialchars($stmt->error));
}
$stmtExecuteResult = $stmt->execute();
if ( false===$stmtExecuteResult ) {
die('execute() failed: ' . htmlspecialchars($stmt->error));
}
else you can use basic PDO. I would use PDO insert with following basic function:
$Query = "INSERT INTO user VALUES (?,?,?,?,?,?,?,?,?,?)";
$Params = array($variables[0],$variables[1],$variables[2],$variables[3],$variables[4],$variables[5],$variables[6],$variables[7],$variables[8],$variables[9]);
$InsertResult = PDOInsert($Query, $Params);
function PDOInsert($Query, $Parameters)
{
try
{
$PDOConnection = new PDO('mysql:host='.DB_HOST.';dbname='.DB_NAME.'', DB_USER, DB_PASS);
$PDOConnection->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
$Statement = $PDOConnection->prepare($Query);
foreach ($Parameters as $Key => $Val)
$Statement->bindValue($Key+1, $Val);
$Statement->execute();
$PDOConnection = null;
return true;
}
catch(PDOException $e)
{
die('ERROR: ' . $e->getMessage());
return false;
}
}
I am running
$this->db->query("SELECT `id` FROM $table WHERE $table.id ='$product_id'");
that should return 92 but its returning the below why?
object(CI_DB_mysqli_result)#150 (8) { ["conn_id"]=> object(mysqli)#16
(18) { ["affected_rows"]=> int(1) ["client_info"]=> string(6) "5.5.30"
["client_version"]=> int(50530) ["connect_errno"]=> int(0)
["connect_error"]=> NULL ["errno"]=> int(0) ["error"]=> string(0) ""
["field_count"]=> int(1) ["host_info"]=> string(25) "Localhost via
UNIX socket" ["info"]=> NULL ["insert_id"]=> int(0) ["server_info"]=>
string(10) "5.5.31-cll" ["server_version"]=> int(50531) ["stat"]=>

["protocol_version"]=> int(10) ["thread_id"]=> int(373292)
["warning_count"]=> int(0) } ["result_id"]=> object(mysqli_result)#161
(5) { ["current_field"]=> int(0) ["field_count"]=> int(1)

["result_array"]=> array(0) { } ["result_object"]=> array(0) { }
["custom_result_object"]=> array(0) { } ["current_row"]=> int(0)
["num_rows"]=> NULL ["row_data"]=> NULL}
It is returning mysqli_ object.So Try to get the result like
$query = $this->db->query("SELECT `id` FROM $table WHERE $table.id ='$product_id'");
$result = $query->result();
foreach($result as $row)
{
echo "Id is ".$row['id']."<br>";
}
And it is appreciable that you are using mysqli_* functions instead of deprecated mysql_* functions
It's returning a mysqli_result object, exactly as the manual says it does.
To get the actual id you need to call fetch_assoc() (or similar) on the object.
if ($result = $this->db->query("SELECT id FROM $table WHERE $table.id ='$product_id'")) {
/* fetch associative array */
while ($row = $result->fetch_assoc()) {
printf ("Fetched ID: %s\n", $row["id"]);
}
/* free result set */
$result->free();
}
Basically the statement:
$this->db->query("SELECT 'id' FROM $table WHERE $table.id ='$product_id'");
returns an object that can be used to extract the result set or table and assigned to a variable... so you need to create a variable and assign the result set to it as:
$mysqli = new mysqli("localhost","rinonymous","03318987165oo","rinonymous");
if ($mysqli->connect_errno) {
print_r($mysqli->connect_error);
exit();
}
$site_title = "Rinonymous";
$page_title = "";
$page_body = "";
#Page Setup
$query_page_info = "select * from pages where id = 1";
foreach ($mysqli->query($query_page_info) as $row) {
print_r($mysqli->query($query_page_info));
#query method returns an associate array
print_r($row);
$page_title = $row['title'];
$page_body = $row['body'];
}
I have following function
<?php
error_reporting(E_ALL); ini_set("display_errors", true);
# $dbh= new mysqli('localhost', 'root', 'hsenidsoft', '1005');
$stmt = $dbh->prepare("CALL populateDefaultTrainStructureTest(?,?)");
$startdate = '2011-05-16';
$counter =1 ;
$stmt->bindValue(1, $startdate, PDO::PARAM_DATE);
$stmt->bindValue(2, $counter, PDO::PARAM_INT);
$stmt->execute();
?>
when i execute the function i got
Fatal error: Call to undefined method mysqli_stmt::bindValue() in /var/www/sp.php on line 8 error
var_dump($stmt)
object(mysqli_stmt)
#2 (9) { ["affected_rows"]=> int(0) ["insert_id"]=> int(0) ["num_rows"]=> int(0) ["param_count"]=> int(2) ["field_count"]=> int(0) ["errno"]=> int(0) ["error"]=> string(0) "" ["sqlstate"]=> string(5) "00000" ["id"]=> int(1) } Fatal error: Call to undefined method mysqli_stmt::bindValue() in /var/www/sp.php on line 11
There is no bindValue function but there is mysqli_stmt::bind_param
