I am inserting a row into a MySQL table from PHP and running a query right after the insert to get the key value of the row that was just inserted like so:
$stmt = $this->db->prepare("INSERT INTO user(vFirstName, vLastName, vEmail, vPassword, iSkilllevelid, vTournaments, vDays, dAddedDate, eStatus) VALUES (?,?,?,?,4,'Pick-Up','Saturday',NOW(),'Active')");
$stmt->bind_param("ssss", $firstName, $lastName, $email, $pwd);
$stmt->execute();
$stmt->close();
$stmt = $this->db->prepare('SELECT iUserId FROM user WHERE vEmail=?');
$stmt->bind_param("s", $email);
$stmt->execute();
$stmt->bind_result($iUserId);
while ($stmt->fetch()) {
break;
}
After this code executes, $iUserId has the correct auto incremented key value (1143 for instance), but when I actually look at the database table, the row with that key (1143) does not exist. How is that possible??
Instead of selecting from the table after insertion, you should use mysqli::$insert_id:
$stmt = $this->db->prepare('
INSERT INTO user
(vFirstName, vLastName, vEmail, vPassword, iSkilllevelid,
vTournaments, vDays, dAddedDate, eStatus)
VALUES
(?,?,?,?,4,"Pick-Up","Saturday",NOW(),"Active")
');
$stmt->bind_param('ssss', $firstName, $lastName, $email, $pwd);
$stmt->execute();
$iUserId = $this->db->insert_id;
$stmt->close();
As to why the inserted data is not appearing from other connections, it seems likely that your transaction has not been committed:
$this->db->commit();

If I have a basic insert query like so:
$stmt = $db->prepare("INSERT INTO table (row) VALUES (?)");
$stmt->bindParam(1, $value);
Can I just call the execute in a if statement like this to check if the insert was succesfull?
$stmt = $db->prepare("INSERT INTO table (row) VALUES (?)");
$stmt->bindParam(1, $value);
if ($stmt->execute()){echo "success"}
or do I have to call it first and then call it again in an if statement ?
$stmt = $db->prepare("INSERT INTO table (row) VALUES (?)");
$stmt->bindParam(1, $value);
$stmt->execute()
if ($stmt->execute()){echo "success"}
Calling $stmt->execute() twice will execute it twice.
It's better to use try and catch since prepare() and bindParam() may also fail:
try {
$stmt = $db->prepare("INSERT INTO table (row) VALUES (?)");
$stmt->bindParam(1, $value);
$stmt->execute();
echo 'Success';
} catch (PDOException $e) {
echo 'Error: '.$e->getMessage();
}
I am having a weird problem with a insert statment. What's happening is that if I insert into only one column, it works but anything greater than 1 column doesn't get inserted and there are no errors displayed
This works
$db = mysqli new('localhost','root','','db');
$stmt = $db->prepare("insert into test (id) values(?)");
echo $db->error;
$stmt->bind_param("s",$id);
$stmt->execute();
But not this:
$id = 1;
$name = "test";
$stmt = $db->prepare("insert into test (id,name) values(?,?)");
echo $db->error;
$stmt->bind_param("ss",$id, $name);
$stmt->execute();
Does anyone have a clue? Not sure if this is helpful but some of the columns don't have a value under collation tab and others have latin1_swedish_ci in the table
Try to bind parameters separately, Like below:
$stmt = $db->prepare("insert into test (id,name) values(:id, :name)");
echo $db->error;
$stmt->bind_param(":id", $id);
$stmt->bind_param(":name", $name);
$stmt->execute();
I have two tables, reports and events, each table has a unique identifier called id with Auto increment, the problem is that the id in each table is not the same because a report can have events but maybe not. I would like to make a double insert but one column in each table must have an unique key. I do this with the following function:
function addactioneventuser(){
try {
$this->conn->beginTransaction();
$query = "INSERT INTO
" . $this->table_name . "
SET
case_id = ?,
from_to = 0,
action_id = ?,
accepted = 0,
message = ?";
// prepare query statement
$stmt = $this->conn->prepare($query);
// bind values
$stmt->bindParam(1, $this->case_id);
$stmt->bindParam(2, $this->action_id);
$stmt->bindParam(3, $this->message);
// execute the query
$stmt->execute();
// insert event query
$query2 = "INSERT INTO event_case
SET
title = ?, body = ?, class = ?, start = ?, end = ?, case_id= ?, worker_id = ?";
// prepare query statement
$stmt = $this->conn->prepare($query2);
// bind values
$stmt->bindParam(1, $this->title);
$stmt->bindParam(2, $this->body);
$stmt->bindParam(3, $this->class_event);
$stmt->bindParam(4, $this->start);
$stmt->bindParam(5, $this->end);
$stmt->bindParam(6, $this->case_id);
$stmt->bindParam(7, $this->worker_id);
// execute the query
$stmt->execute();
$this->conn->commit();
return true;
} catch (Exception $e) {
$stmt->rollBack();
return false;
}
}
The two inserts works perfectly but my problem is that the two ids for each table are not the same and as a consequence I can not delete at the same time an specific record from both tables and I don't know how to do it. I read about Cascade and other possible solutions but none of them seem pausible for my problem. I don't mind to create another column to use it as reference for both tables but I don't know how to do it in the above query.
Thank you in advance
Last insert id is $this->conn->insert_id;
You can get it after the operation and use the identifier.
For example to add it to the desired table
I am simply trying to insert the variable from a session into a MySQL database and it causes it to fail. var_dump shows SESSIONS all there. No problem there. Why doesn't this work?
$job = $_SESSION['job'];
$user_id = '1';
$name = 'allie';
$stmt = $mysqli->prepare("INSERT INTO
requests(name,job_info,user_id)
VALUES (?,?,?)");
$stmt->bind_param('sss', $name, $job, $user_id);
$stmt->execute();
see pdo bind_param
your parameter is incorrect:
change this:
$stmt->bind_param('sss', $name, $job, $user_id);
with this:
$stmt->bind_param(1, $name, PDO::PARAM_STR);
$stmt->bind_param(2, $job, PDO::PARAM_STR);
$stmt->bind_param(3, intval($user_id), PDO::PARAM_INT);
I have this following example query, which works - I CAN insert values into my MySQL table, which also includes an unique id column. I want to get the id from the inserted row, after I execute the query. However what I get is 0 every time ($gotId=0).
What am I doing wrong?
$stmt = $conn->prepare("INSERT INTO ....... ");
$stmt-> bind_param("ss", ....);
$stmt->execute();
$gotId = $conn->insert_id;
Full query:
$conn = $db->connect();
$stmt = $conn->prepare("INSERT INTO table(value1, value2) VALUES(?, ?)");
$stmt-> bind_param("ss", $value1, $value2);
$stmt->execute();
$gotId = $conn->insert_id;
After calling the execute() method on the PreparedStatement, the id of the insert row will be in the insert_id attribute Only read it.
$stmt->execute();
$gotId = $stmt->insert_id;
Taken from here
$query = "INSERT INTO .......";
$mysqli->query($query);
printf ("New Record has id %d.\n", $mysqli->insert_id);
