The products will have different option values, and the php script will grab the option values and echo them in a form to post back to the cart to add the product to the basket. The problem is that the "product_option_value_id" can have lots of different values, but my code echos only the first one it finds. So when I click the add to cart button, it will only add the first option value for the product it finds. For some reason I am having a hard time explaining this, so I hope someone can help me. Thanks for looking. hey guys, I'm getting a problem uploading my csv file to mysql database, the code on the top half just makes sure that I don't import data that I don't want into the database, numbers that are too high or too low on certain rows, and the second half is importing the array that I create from the csv file into the database however I'm getting the following error

Hi, I got this script which checks a username does not exist, before writing the users registration info to the database. It was working fine, but now for some reason says there is a duplicate username in the database, when there isnt Code: [Select] <?php $password1 = $_POST['password1']; $password2 = $_POST['password2']; if ($password1 != $password2) { echo "Your passwords did not match, please go back and register again"; } else { // Check Passwords Match // Get Posted Variables $username = $_POST['username']; $firstname = $_POST['firstname']; $lastname = $_POST['lastname']; $address = $_POST['address']; $town = $_POST['town']; $county = $_POST['county']; $postcode = $_POST['postcode']; $email = $_POST['email']; $approved = "no"; // MySQL Connection include_once("data/mysql.php"); $mysqlPassword = (base64_decode($mysqlpword)); $con = mysql_connect("$localhost", "$mysqlusername", "$mysqlPassword") or die(mysql_error()); mysql_select_db("$dbname", $con) or die(mysql_error()); $query = "SELECT COUNT(*) AS count FROM members WHERE username='$username'"; $results = mysql_query($query) or die ("Error reading from database"); $existingUsername = mysql_fetch_array($results); if ($existingUsername['count'] > 0) { echo "I'm sorry our database already contains that username please choose a new username to continue."; } else { $sql = "INSERT INTO members (username, firstname, lastname, address, town, county, postcode, email, password, approved) VALUES ('$_POST[username]','$_POST[firstname]','$_POST[lastname]','$_POST[address]','$_POST[town]','$_POST[county]','$_POST[postcode]','$_POST[email]','$_POST[password2]','$approved')"; mysql_query($sql,$con); ?> <meta http-equiv="REFRESH" content="5;url=../login.html"> <?php } mysql_close($con); } ?> Im sure it is something simple, I just cant see what it is. As always, any help is much appreciated When there is a duplicate entry in my database, I would like it to go to the another page that indicates the error, rather than the "Error: Duplicate entry 'username' for key 1". It happens if someone is going to join and there is a duplicate entry. I would rather it show one of my customized php pages rather than a black page stating the error. I've tried to catch the entry with some php code but it bypasses it and continues with the duplicate error. I would appreciate any direction with this. Thanks! MySQL returns an error in the form of a number, a state, and a message. Without parsing the message you will not be able to determine what column is duplicated.While parsing the error code, I have also notice that, if you have multiple unique fields as duplicates, only the first duplicate encountered will be returned in the message. This is not very helpful to the end user.
Is there any way to parse the returned error code to reflect all duplicate fields, please see sample code below?
$error=array();
$sql = 'INSERT INTO staff(username, email, phone)
VALUES (?, ?, ?)';
$stmt = $conn->stmt_init();
$stmt = $conn->prepare($sql);
// bind parameters and insert the details into the database
$stmt->bind_param('sss', $username, $email, $phone);
$stmt->execute();
if ($stmt->errno == 1062) {
$errors[] = "One of the fields is already in use.";
}
Alright, wasn't quite sure how to summarize this in the title, but I want to: Check if a user status is "active" or not based on the UserName input. I have a table witch holds: Code: [Select] VarChar Username Var CharPassWord int Active Ted TedsPW 1 something like the above(assuming it formatted correctly. In my php script I will want to input a variable for Username to check for: inputUN in this example would be "Ted". $UserNameToCheck = $_GET['inputUN']; Then I want to check for that UserName in the database, if it exists, I want pull the value for the "Active" field for just that UserName and echo it. Thanks for any help. I am using php to upload a file to my server, and at the same time inserting the files name and url into my mysql database.
$sql = "UPDATE uploads SET name = '$name', url='$target_path'";
$statement = $dbh->prepare($sql);
$statement->execute();
This is working, however, when I upload a new file, rather than making a new entry in my database, it just overwrites the first one.I'm quite new at mysql so was wondering how I would make it add new entrys instead of overwriting the current one? If I am using this: Code: [Select] mysql_query("INSERT INTO M1QuizResults (Email, Q1Choice, Q2Choice, Q3Choice, Score, Pass, Date_Taken, Time_Taken) VALUES(' " . $_SESSION['Email'] . " ', '$QChoice_1', '$QChoice_2', '$QChoice_3', '$Score', '$Pass', CURDATE(), NOW())") or die(mysql_error()); What would I use to find out what the row's "Id" is? "Id" is my primary key. I want to store this "Id" as a session variable. thanks! I can't figure out where this is going wrong. But it obviously has to do with the primary key for the table. Here is the code:
//set led request
if ( isset ( $action ) && $action == 'submit_led_request' ) {
$order_id = $_GET['order_id'];
$products = explode(',', $_GET['product']);
$qty = explode(',', $_GET['qty']);
//make sure the same of number of records exist in each array
if ( count ( $products ) == count ( $qty ) ) {
$original_request_id = $pdo->query("SELECT MAX(id) FROM leds_requests LIMIT 1")->fetch(PDO::FETCH_NUM)[0] + 1;
for ( $i = 0; $i <= count ( $products ) - 1; $i++ ) {
$query = "INSERT INTO leds_requests (original_request_id, order_id, user_id, product_id, qty, status_id) VALUES (:original_id, :order_id, :user_id, :product_id, :qty, 0)";
$statement = $pdo->prepare($query);
$statement->execute([
'original_id' => $original_request_id,
'order_id' => $order_id,
'user_id' => $_SESSION['user_id'],
'product_id' => $products[$i],
'qty' => $qty[$i],
]);
}
//setup variables for system wide message function
$send_to_users[] = ['user_id' => 54]; //r
$send_to_users[] = ['user_id' => 49]; //b
$send_to_users[] = ['user_id' => 55]; //g
$send_to_users[] = ['user_id' => 1]; //j
$message = 'An LED pull request has been made by: ' . get_user_full_name($_SESSION['user_id'], $pdo) . '. Please go to the LED Request Manager to review the request.';
//send the messages
$chat_message_id = send_system_message( $message, $send_to_users, $order_id, $pdo );
//establish relationship for messages
$pdo->query('
INSERT INTO
chat_message_rel_leds(
chat_message_id,
original_request_id
) VALUES (
'. $chat_message_id .',
'. $original_request_id .'
)
');
}
else {
exit();
}
}
Here is a screenshot of the problem:
If you look at row 235 and 236, they have a value of 233 and 234 in the 'original_request_id' column. If you look below 235, the last key was 232 so that should have been correct (original_request_id should be the initial key assigned to the record from the table). Is my method for determining what that key is going to be fault in some way? IE:
$original_request_id = $pdo->query("SELECT MAX(id) FROM leds_requests LIMIT 1")->fetch(PDO::FETCH_NUM)[0] + 1;
From what I understand, there isn't a way in PDO to get the current max primary key except after an insert function is performed. Is this correct and am I doing something wrong here? I have a form that ask user to enter other details but the primary key as this is automated and when they click on Submit button it takes the user to different form. now on this form I would like to retreive the primary that has just been added to the table. How can I do this? I am using function to insert into database. But the primary key is automatic and I used Quote $_SESSION['Tes_ID'] = mysql_insert_id(); to retrieve this. But now that I use function method. I am not sure how to retrieve the primary key on to the next page. Code: [Select] $value = modulesql($postVar1, $postVar2, $SessionVar1, $SessionVar2); $_SESSION['Tes_ID'] = mysql_insert_id(); echo $value, $_SESSION['Tes_ID']; Code: [Select] <?php function modulesql($Tes_Name, $Tes_Description, $Use_ID, $Sub_ID){ $con = OpenConnection(); mysql_select_db("examination", $con); $module = ("INSERT INTO test (`Tes_Name`, `Tes_Description`, `Use_ID`, `Sub_ID`) VALUES ($Tes_Name, $Tes_Description, $Use_ID, $Sub_ID)") or die('Cannot Execute:'. mysql_error()); CloseConnection($con); return $module; } ?> Have I lost you with my question?? I have a successful select query, where I'm looping and building a row for getting parameters which works correctly while ($row = $orderDetailCheck->fetch(PDO::FETCH_ASSOC)) {
$params = [ } My issue now is that, for each row, I need to perform two merges because the data from that select is going to be split into two tables in db2. Some values are truly split between the tables but some values are shared between the two. I'm not sure the best way to perform these two merges because if the first one (products table) inserts, then it creates an ID that I need as a foreign key basically, to insert into the orders table. So on insert I need to grab that newly created ID and use it for ```product_id``` in the second merge. If the first merge performs the update when matched, then I need to grab the existing ID for that record so that I can update the proper record in the orders table. My two merge statements:
/*products table*/
:GROUP,
)
AS S(GROUP,DTL12,DTL13,CUSTNM,SELLINGN,COUNT_PLMN_1,LAST_DATE)
WHEN MATCHED
WHEN NOT MATCHED
/*ORDERS Table*/
/*need foreign key, which is id from products table*/
AS S(PRODUCT_ID,quantity_ordered,LAST_DATE,invoice_number)
WHEN MATCHED
WHEN NOT MATCHED Examples:
INVOICE | CUSTNM | SELLINGNUM | GROUP | DTL12 | DTL13 | QUANTITY | COUNT_PLMN_1 | LAST_DATE
products
ID | GROUP | DTL12 | DTL13 | CUSTNM | SELLINGNUM | COUNT_PLMN_1 | LAST_DATE
ORDERS
PRODUCT_ID | QUANTITY_ORDERED | LAST_DATE | INVOICE
INVOICE | CUSTNM | SELLINGNUM | GROUP | DTL12 | DTL13 | QUANTITY | COUNT_PLMN_1 | LAST_DATE
products
ID | GROUP | DTL12 | DTL13 | CUSTNM | SELLINGNUM | COUNT_PLMN_1 | LAST_DATE and update orders like so: ORDERS
PRODUCT_ID | QUANTITY_ORDERED | LAST_DATE | INVOICE I guess the main question is: How can I get the ID of a record from the products table (whether it's an existing match OR newly created in the merge) and once I get it, how can I use it for the 2nd merge? Hi, I am trying to build a function that takes in the current primary key as a parameter. My question is how do I extract it/retrieve it and store it in a variable? Any help is much appreciated! |
