PHP - Failed Transaction Upsets The Auto Increment Values
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.
Similar Tutorialsok, 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. 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 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. 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?

So, when someone creates a new organization, it will copy the new auto-increment value into the org_id field. Is this possible? Thanks! is there a way to save a field in a session or variable while its being inserted into the data base? with out having to select it using another query $mail2 = "INSERT INTO pm SET pm_id = '', (turn pm_id into a $variable or session) WHERE blah blah blah the problem im having is Im creating two rows right after each other where each row is in differant tables and I need them to match ids and I have nothing to compare it to. only option i can think of is making a fast toggle switch or telling my select to grab in order which would work.

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?
hi, i’m currently facing a new problem (i managed to use array_unique function successfully but i face this problem)with my php loop. i couldn’t seem to increment in my foreach loop to get the value of an array. $update_id1=Array ( [0] => 398 [1] => 397 [2] => 393 [3] => 391 [8] => ); //$i=0; foreach ($update_id1 as $i => $v) { $ex= explode(",", $v); $unique=array_unique($ex); //f$ketch username from update table in db and inject it to the feed query. $imp_id= implode(',', $ids); //$id1=$ids[$i]; // $x=0; // for($x=0;$x<count(unique);$x++){ echo 'ids:- '.$i; print_r($unique[$i]); echo '<br>'; //} $totalUpdates=$project->totalUpdates($ids[$i],$_SESSION['uname'] ,$unique[$i],$load); //$i++; } i tried every method nothing seems to work can anyone help me in this regard please. Edited December 25, 2019 by narutofanI'm just learning about PHP and I'm diving in head first by attempting to modify our web site's contact form. I'm wishing to stop the form from erasing previously entered values upon "failed" data validation. It's of course going to be annoying to our visitors if their hardworked entries disappear just because they left out a name or entered an illegal email address. I regret that some potential solutions found on this forum and other locations on Google didn't seem to help on my page. As you can see, the validation is done with PHP's version of if-elseif-else. Later I'll be adding a reCAPTCHA and I hope that whatever I learn here might be useful for the potentially same problem when I am adding the CAPTCHA. The actual contact form is at http://www.woofwoofwoof.org/contact/index.php. Thank you in advance for your taking the time to help me what originally appeared to be a simple problem. I have read the rules and I hope I've followed the rules -- please let me know if I committed any sins of omission or commission.

I mess with php strictly for my own amusement. Up until now I have been able to Google my way to a answer to my questions but I'm lost on this one. I'm not really sure what to even search for. I have a few different mysql queries that returns the following arrays. qid15=37,37,37,37,37,37,37,37,37,37,37,38,38,39,39,41 qid17=47,47,47,47,47,48,49,49,49,50,50,50,51,51 qid18=52,52,52,52,52,52,52,52,54,54,55,55,55,56,56,56 qid19=57,57,57,57,58,59,59,61,61 What I would like to do is replace or create a new array for each result with the lowest value as 1 the next lowest as 2 then 3 and 4. My new array would look something like this oldqid15=37,37,37,37,37,37,38,38,39,39,41 newqid15=1,1,1,1,1,1,2,2,3,3,4 I sure would appreciate any ideas on this. I'm thinking there is probably a simple solution and before I waste anymore time I'll stop and ask for directions(as my wife would suggest). So I need to build into a PHP/MYSQL system I currently have a way for admins to see a list of things done through the CMS by all users. Any ideas? I am looking to see if I could use one of the paypal features to pay two diffierent account from a single transaction and does paypal does that automatically?.. I was checking the immediate payment for a third party from the express checkout but I don't know that much about it. Does anyone knows how to achieve this? Ok, so I am kind of just looking for some experience on this one. I am building a billing / referral system that works on a hierarchy. Now the hierarchy is simple and straight forward. However, I am trying to figure out the easiest / least error prone way of handling the payments. I have an IPN with paypal set up and working successfully. Here is how the system works: User signs up and refers several users. Each user pays $8 a month (paypal subscription). The system pays $1 7 levels deep. So The payment scheme would look like this: User 8 pays $1 to User 7, 6, 5, 4, 3, 2, and user 1. Then, the site keeps the remaining $1. I have the Paypal IPN saving the $8 payment transaction to the database. Now I need to divy it up, but I am split on when the best time to do this would be and how. There is a possibility that the user could pay a different amount less than or more than the $8 and they also pay a setup fee which should not be divided. It should only divide the shares when the current account is paid in full. Another thing to keep in mind, is that the $8 subscription, 7 levels deep, and the setup fee are variable numbers. (The admin may change it at any time.) I see multiple solutions, but not sure which would be best as all have possibility for errors in handling. Any advice would be helpful. Thanks, Tom Customers can view transaction history for approved and declined transactions (the reason for the decline should be included). Transactions are logged with their transaction reference numbers and status. |
