PHP - Putting A Unique Auto Increment Id Into A Session Variable Without A Queryt
I've been trying to grab the unique auto incrementing table id and put into a session variable.
$name_id = mysql_insert_id(); $query = sprintf("INSERT INTO profile ( name_id, bio, ex) VALUES (LAST_INSERT_ID(),'%s','%s')", mysql_real_escape_string($_SESSION['pro']['bio']), mysql_real_escape_string($_SESSION['pro']['ex'])); $result = mysql_query($query, $db) or die(mysql_error($db)); $name_id = mysql_insert_id(); $_SESSION['name_id'] = $name_id; //this is the key line $_SESSION['logged'] = 1; header('Refresh: 5; URL=main.php'); I've echoed out the result of $_SESSION['name_id'] and it says '0'. I've tried changing the key line to $_SESSION['name_id'] = LAST_INSERT_ID(); but I get this error message: Fatal error: Call to undefined function LAST_INSERT_ID() in C:\x\xa Is my goal acheivavle or should I just set up a select query after the insert query and extract the id key? Similar TutorialsHello! Everybody in my class have their own folder on a domain, so its like: www.thedomain.no/nameofstudent. The problem we are facing is that when i log in on my site i also get logged in on all the other students sites too... (we are all using Dreamweaver CS5.5) We all have a: Welcome, USERNAME, massage on our sites. However if i first log in on my site, then visit another students site i get the massage: Welcome, (and the username i logged in with on my site!) another problem is when i try to access the shopping cart of student X's site (then i get redirected to the loging page on his site), If i then leave that tab open in chrome and open a new one, then i go to my login page in than new tab ON my site, then i log in on my site. Instead of getting redirected to MY index i get redirected to student X's shopping cart... I tried to rename the Session variable without luck. (default dreamweaver is $_Session['MM_Username']) Any Suggestions? Hope i made myself understandable Thanks Hey, In my table, I have 773 rows like this: 10800 ... 772 ... 771 ... 770 ... 769 ... etc ... When I insert a new row, it will have an ID of 10801 and not 773. I delete row 10800 and I want to insert a new row that has an ID of 773. Is there a code I can use also so that it creates the IDs in order? 1, 2, 3 etc no missing numbers. Thanks. Hello, I am creating a job setup form and have a need for the job id field to increment based on the last inserted job id into our Oracle database. So far I have created a function that selects the maximum job id from the job table and adds 1 to the number. However, I run into the problem of when a user is filling out the form and another user opens it and begins filling out the form they both will receive the same job id in the field. I'm assuming this could possibly be solved with sessions, but I'm not sure where to start. Also, the form is not inserted into the table on submit (instead an excel sheet is created with the information and someone will enter the data into the database manually). Since the form data can be entered anytime from completion to next week/two weeks, how can I ensure that that job id is not used again. Thanks Hi, I have coded a lot in the past but only now getting into PHP and web coding in general, when I use a while loop in most other languages I need to increment some form of counter to move to the next item e.g. Code: [Select] while (count < 10) { Do something; count + 1; } I am going through a set of tutorials that have just enlightened me to the following code when looking up a MYsql d'base: Code: [Select] $reults = "SELECT * FROM table"; while ($row = mysql_fetch_assoc($results)){ extract($row); echo $tblcol1; echo " - "; echo $tblcol2; echo "<br>"; } Now in fairness I have no real problem with this, if thats how you extract your results from a query then fine but I feel I am missing something and have not been able to nail it on the head. Am I to assume that $row in the loop returns the first row from the query results, moves through the actions of the loop, returns then automatically points to the next row of the array? Does that mean while($row){} where $row is a 3x3 array(for example) it would loop through this 3 times assigning the next row until the end? Is there a better way to explain this? ok, how do I add an auto incremented value to another table at the same time the value is created. so I will do a query to insert into db, and it creates auto incremented value of 1, then I need this value to also be put into another table just as text. how do I go about doing this? I need this all in one query. Is there a way to copy an auto-increment value (`id`) into another field in the same table (`org_id`)? So, when someone creates a new organization, it will copy the new auto-increment value into the org_id field. Is this possible? Thanks!

This topic has been moved to MySQL Help. http://www.phpfreaks.com/forums/index.php?topic=321437.0 Hi everyone,
I have an application that makes use of a transaction, inserting and updating values in different tables. One of the first tables it inserts into has an auto increment ID field. This ID values is used / updated in some other tables. Everything works fine. If however the transaction fails then the auto_increment values are upset - meaning that the sequence is jumped.
For ex. if I had auto_increment values from 1 to 6 in this table and then the insert query fails for an auto_increment value of ID=7, then this value of ID = 7 is lost because the next time the query is run the auto_increment ID value will be equal to 8 and accordingly updated in the tables. ID value = 7 is lost. Is there any way to prevent this ? Please know that this is a multi - user application.
Thanks.
i'm need to retrieve a session after i've collected the data and went to PayPal (...urk...) i think i'm starting off correctly... but how the hell do i get the session name on the other side? Code: [Select] $uuid = uniqid(); session_name = $uuid; session_start(); // do some stuff // go to PayPal // come back from PayPal ....um... now i'm lost! how do i get the $uuid here?? once i come back from PayPal... this is where i get lost. how do i load a UUID-based session if i can't get the $uuid? and if there's a better way, by all means let me know! someone said i could pass the $uuid through PayPal, but i'm not seeing how yet... TIA gang! WR! I have a dropdown menu <td width="148" height="35" valign="top"><b>Type: </b> </td> <td><select name ="tabledrop"> <option value="goggles">goggles</option> <option value="headbands">headbands</option> <input type='hidden' id='tabledrop' name='tabledrop' value = ''/> </select> </td> those 2 options are actually names of my tables. I tried this and got some syntax error. $type = $_POST['tabledrop']; $item = $_POST['goggles_name']; $price = $_POST['goggles_price']; $file = $_FILES['goggles_image']['name']; $query = "INSERT into $type SET [$type]_name = '$item' , [$type]_price = '$price' , [$type]_image = '$file'"; I'm trying to take a number of items from a database using a while loop and put the results into a variable so that I can send one email with all the results. I'm having trouble figuring this out though. Can anyone please give me any ideas as to how to make this work? Here's what I've done so far... all it does is result in an email with the first set of results in the while loop, not all of them.

For some unapparent reason, i'm getting errors stating that $user and $priv are undefined variables, though I've attempted to define $user as being equal to $_SESSION['name'], using $user to look up the the user's privilege level (stored as the su column ) in the SQL table, and then where the result of the sql query is $priv which is then evaluated in an if statement. I can't seem to figure out why this might not be working. The code I'm using: <?php session_start(); function verify() { //verify that the user is logged in via the login page. Session_start has already been called. if (!isset($_SESSION['loggedin'])) { header('Location: /index.html'); exit; } //if user is logged in, we then lookup necessary privleges. $_SESSION['name'] was written with the login name upon login. Privleges // are written in db as a single-digit integer of of 0 for users, 1 for administrators, and 2 for special users. $user === $_SESSION['name']; //Connect to Databse $link = mysqli_connect("127.0.0.1", "database user", "password", "database"); if (!$link) { echo "Error: Unable to connect to MySQL." .

Hello everyone, I can get Test 2 to successfully operate the if statement using a variable variable. But when I try the same method using a session variable (Test 1) the if statement is not executed. Please could you tell me why the if statement in Test 1 is not being executed? Code: [Select] <?php # TEST 1 $_SESSION[test_variable] = "abcd"; $session_variable_name = "_SESSION[test_variable]"; if ($$session_variable_name == "abcd") { echo "<br>line 373, abcd<br>"; } # TEST 2 $test_variable = "efgh"; $test_variable_name = "test_variable"; if ($$test_variable_name == "efgh") { echo "<br>line 379, efgh<br>"; } ?> Many thanks, Stu Basically I'm trying to set up a shopping cart using PHP & MySql (oh really!?) and I've gotten to the point where I need to insert the bought products into a database. Currently, at the checkout, there is a session which stores data for all of the products which have been added into the cart. From here I am just trying to create an order id code that is only relevant to this session. So in the database it would end up looking something like this: order_id = 001, product_id = 2, order_quantity = 3 order_id = 001, product_id = 4, order_quantity = 2 order_id = 001, product_id = 1, order_quantity = 5 order_id = 002, product_id = 2, order_quantity = 3 order_id = 002, product_id = 4, order_quantity = 2 order_id = 002, product_id = 1, order_quantity = 5 So I would be able to pull these results later by selecting the order relevant to the order_id. At least I think this is the easiest option for me. Every product which is put into the cart has a $_SESSION name of 'product_x', 'x' being the id associated with that product Any help? Hi Guys Ever had the feeling your being a spoon and can't see the wood for the trees? Well, that's how I feel today. All I am trying to to is implement a variable in a "foreach" loop that increments by one through each iteration of the loop. I know how to do it in a "for" loop but can't for the life of me get it to work here. Here is the code: foreach ($cart as $prodcode => $qty) { $item = get_product_details($prodcode); echo '<input type="hidden" name="item_name_'.[b]$needavariablehere[/b].'" value="'.$item['description'].$_SESSION['finish'][$prodcode].$_SESSION['handles'][$prodcode].'" />' . "\n"; } Where I have highlighted $needavariablehere is where I want a number to appear i.e. if there is one item available and the foreach loop iterates once I want the number 1 here. If there are two items and the foreach loop iterates twice I want the output to have number 1 in the first line and number 2 the second time around and so on. How many times the foreach loop iterates is based on the $cart array which contains items in a shopping cart. Thanks for any help you can give guys. I have a mysql table which will store users email addresses (each is unique and is the primary field) and a timestamp. I have added another column called `'unique_code' (varchar(64), utf8_unicode_ci)`. What I would very much appreciate assistance with is; a) Generating a 5 digit alphanumeric code, ie: 5ABH6 b) Check all rows the 'unique_code' column to ensure it is unique, otherwise re-generate and check again c) Insert the uniquely generated 5 digit alphanumeric code into `'unique_code'` column, corresponding to the email address just entered. d) display the code on screen. What code must I put and where? **My current php is as follows:** Code: [Select] require "includes/connect.php"; $msg = ''; if($_POST['email']){ // Requested with AJAX: $ajax = ($_SERVER['HTTP_X_REQUESTED_WITH'] == 'XMLHttpRequest'); try{ if(!filter_input(INPUT_POST,'email',FILTER_VALIDATE_EMAIL)){ throw new Exception('Invalid Email!'); } $mysqli->query("INSERT INTO coming_soon_emails SET email='".$mysqli->real_escape_string($_POST['email'])."'"); if($mysqli->affected_rows != 1){ throw new Exception('You are already on the notification list.'); } if($ajax){ die('{"status":1}'); } $msg = "Thank you!"; } catch (Exception $e){ if($ajax){ die(json_encode(array('error'=>$e->getMessage()))); } $msg = $e->getMessage(); } } |
