PHP - Transactions In Php-mysql Appliations
must we always use Transactions in php-mysql applications?
i kind of made a self-discovery for a problem i was trying to solve....and found that mysql transactions would solve my problem. i wanted a set of SQLs to all be executed, or none an with undo of partial successful updates. is this transactions the standard way, and is this a must-do for realtime applications? any pros/cons/advise? thanks! Similar TutorialsHello all. I have never used transactions before and I'm building a website right now and trying to use one. Now, the question here is do I use it right? I have 3 tables, posts, users and users_to_posts which holds all ids (id, user_id, post_id). Now as I need to get the last insert id from database, I need to lock tables cause when two people post at the same time, it might get all mixed up. Now I use the lock tables statement first time. Anyway, all this story aside, the question. Do I use this block right? if(isset($_SESSION['uID'], $_SESSION['username'])) { // User try { $dbh->beginTransaction(); $stmt = $dbh->exec('LOCK TABLES `posts` WRITE, `users_to_posts` WRITE'); $insert = $dbh->prepare('INSERT INTO `posts` (`content`) VALUES (:content)'); $insert->bindParam(':content', $post, PDO::PARAM_STR, 350); $insert->execute(); $jointbl = $dbh->prepare('INSERT INTO `users_to_posts` (`user_id`, `post_id`) VALUES (:uID, :pID)'); $jointbl->bindParam(':uID', $_SESSION['uID'], PDO::PARAM_INT, 11); $jointbl->bindParam(':pID', $dbh->lastInsertId(), PDO::PARAM_INT, 11); $jointbl->execute(); $unlock = $dbh->exec('UNLOCK TABLES'); $dbh->commit(); } catch(PDOException $e) { echo $e->getMessage(); } } Oh, just in case. There are no errors, it works. I just want to know if it's the right way to use it. Hello, I would like show entries on a list based on their PayPal status. If it is "pending" I don't want them to show on the list. only if their status is "complete". I just recently switched over to WPForms for WordPress. They offer only a basic PHP file that creates a list but they do not support any modifications to that file. What would I need to do to this code to produce the results I need? Please see attached files and code pasted below. Thanks for your help, Steve
<?php
$data = preg_replace("/[^a-zA-Z' ']/", "", $data); } break;

Hi all, I have some financial transactions to perform in my system like cash deposits, withdrawals etc.I have built my system using PHP and MySQL. Can someone explain me how can i use rollback operations if something failure occurs? Heshan, How do you guys keep bookkeeping records of transactions?
An example is you pay for a domain name, monthly hosting or anything that you receive an email receipt for and a receipt is stored on the vendors website. Say up to 7 years.
Hi, I'm trying to insert data into two different tables using, but am getting an error I can't figure out. If I move the $mysqli->commit(); into the foreach loop, I get at least one returned row before the rest fail. The error current error message is Array ( [0] => Error: Couldn't insert into english! ). Any idea what is causing this?
<?php
$file_array = file('../grammar/conjunctions.txt');
$csv = array_map('str_getcsv', $file_array);
// DB
$mysqli = new mysqli('localhost', 'root', '******', 'angos');
$mysqli->autocommit(false);
$error = array();
foreach($csv as $value)
{
$angos_query = $mysqli->query("INSERT INTO angos (angos, grammar) VALUES ('$value[0]', 'con')");
$id = $mysqli->insert_id; // grab the currant angos table id
if($angos_query == false)
{
array_push($error, "Error: Couldn't insert into angos!");
}
$english_query = $mysqli->query("INSERT INTO english (angos_id, english) VALUES ('$id', '$value[1]')");
if($english_query == false)
{
array_push($error, "Error: Couldn't insert into english!");
}
if(!empty($error))
{
$mysqli->rollback();
}
}
$mysqli->commit();
print_r($error);
// print_r($csv);
?>
More info SQL:
CREATE TABLE angos

i want to download pdf or text document after clicking button or link how to do that Hello everyone, Sorry if this has been answered but if it has I can't find it anywhere. So, from the begining then. Lets say I had a member table and in it I wanted to store what their top 3 interests are. Their$ row has all the usual things to identify them userID and password etc.. and I had a further 3 columns which were labled top3_1 top3_2 & top3_3 to put each of their interests in from a post form. If instead I wanted to store this data as a PHP Array instead (using 1 column instead of 3) is there a way to store it as readable data when you open the PHPmyadmin? At the moment all it says is array and when I call it back to the browser (say on a page where they could review and update their interests) it displays 'a' as top3_01 'r' as top3_02 and 'r' as top3_03 (in each putting what would be 'array' as it appears in the table if there were 5 results. Does anyone know what I mean? For example - If we had a form which collected the top 3 interests to put in a table called users, Code: [Select] <form action="back_to_same_page_for_processing.php" method="post" enctype="multipart/form-data"> <input name="top3_01" type="text" value="enter interest number 1 here" /> <input name="top3_02" type="text" value="enter interest number 2 here" /> <input name="top3_03" type="text" value="enter interest number 3 here" /> <input type="submit" name="update_button" value=" Save and Update! " /> </form> // If my quick code example for this form is not correct dont worry its not the point im getting at :) And they put 'bowling' in top3_01, 'running' in top3_02 and 'diving' in top3_03 and we catch that on the same page with some PHP at the top --> Code: [Select] if (isset($_POST)['update_button']) { $top3_01 = $_POST['top3_01']; // i.e, 'bowling' changing POST vars to local vars $top3_02 = $_POST['top3_02']; // i.e, 'running' $top3_03 = $_POST['top3_03']; // i.e, 'diving' With me so far? If I had a table which had 3 columns (1 for each interest) I could put something like - Code: [Select] include('connect_msql.php'); mysql_query("Select * FROM users WHERE id='$id' AND blah blah blah"); mysql_query("UPDATE users SET top3_01='$top3_01', top3_02='$top3_02', top3_03='$top3_03' WHERE id='$id'"); And hopefully if ive got it right, it will put them each in their own little column. Easy enough huh? But heres the thing, I want to put all these into an array to be stored in the 1 column (say called 'top3') and whats more have them clearly readable in PHPmyadmin and editable from there yet still be able to be called back an rendered on page when requested. Continuing the example then, assuming ive changed the table for the 'top3' column instead of individual colums, I could put something like this - Code: [Select] if (isset($_POST)['update_button']) { $top3_01 = $_POST['top3_01']; // i.e, 'bowling' changing POST vars to local vars $top3_02 = $_POST['top3_02']; // i.e, 'running' $top3_03 = $_POST['top3_03']; // i.e, 'diving' $top3_array = array($top3_01,$top3_02,$top3_03); include('connect_msql.php'); mysql_query("UPDATE members SET top3='$top3_array' WHERE id='$id' AND blah blah blah"); But it will appear in the column as 'Array' and when its called for using a query it will render the literal string. a r r in each field instead. Now I know you can use the 'serialize()' & 'unserialize()' funtcions but it makes the entry in the database practically unreadable. Is there a way to make it readable and editable without having to create a content management system? If so please let me know and I'll be your friend forever, lol, ok maybe not but I'd really appreciate the help anyways. The other thing is, If you can do this or something like it, how am I to add entries to that array to go back into the data base? I hope ive explained myself enough here, but if not say so and I'll have another go. Thanks very much people, L-PLate (P.s if I sort this out on my own ill post it all here) I have following piece of code below, and I would like to be able to express it pure SQL, something that could go into a .sql file :
$request_string='SELECT topic_forum_id FROM topic_table WHERE topic_id= 2014';
$query=database->prepare($request_string);
$query->execute();
$data=$query->fetch();
$query->closeCursor();
$forum=$data['topic_forum_id'];
$request_string='INSERT INTO post_table
(post_topic,post_forum) VALUES (2014,:forum)';
$query=database->prepare($request_string);
$query->bindValue(':forum',$forum,PDO::PARAM_INT);
$query->execute();
$data=$query->fetch();
$query->closeCursor();
Is it possible ?
So i have this php as shown below. It should make a list of comments with comment replies below their comment respectively. The problem is that it only goes through and shows 1 comment and all the comment replies for that one comment. It should be showing all comments i have in the db for that article. If i remove the second while then it shows all the comments correctly but no comment replies then... How do i get this script to loop through the db for every comment but also loop through every comment reply for that $row[id]? If anyone has a better / more efficient way of what I am trying to do, please explain or show example (i am open to anything)... Code: [Select] // what article are we showing? $article_to_show_id = $_GET['article_id']; $active_is_set_text = "1"; // Active Column text that makes it okay to show // Finding the article $search_for_article = mysql_query("SELECT * FROM articles WHERE id = '$article_to_show_id' AND active = '$active_is_set_text'"); while($row = mysql_fetch_array($search_for_article)) { // format the last updated date right $update_date_edit = $row[update_date]; $update_date_edit = date('F j, Y \a\t h:ia', $update_date_edit); $row[update_date] = $update_date_edit; // format the submit updat date right $submit_date_edit = $row[submit_date]; $submit_date_edit = date('F j, Y \a\t h:ia', $submit_date_edit); $row[submit_date] = $submit_date_edit; echo ' <div> ', $row[title] ,' </div> <div> by: ', $row[author] ,' on ', $row[submit_date] ,' </div> <div> ', $row[content] ,' </div> <div> Last Updated: ', $row[update_date] ,' </div> <form action="article_reply.php" method="post"> <input type="hidden" name="article_id" value="', $row[id] ,'" /> <button name="article_reply" type="submit" value="submit">Reply</button> </form> '; } $comment_count = 0; $comment_reply_count = 0; // Finding all of the comments $search_for_article = mysql_query("SELECT * FROM article_comments WHERE article_id = '$article_to_show_id' AND reply_id = '0'"); while($row_comment = mysql_fetch_array($search_for_article)) { // format the submit updat date right $comment_date_edit = $row_comment[comment_date]; $comment_date_edit = date('F j, Y \a\t h:ia', $comment_date_edit); $row_comment[comment_date] = $comment_date_edit; echo ' <br> <br> COMMENT:<br> <div> By: ', $row_comment[username] ,' on ', $row_comment[comment_date] ,' </div> <div> ', $row_comment[comment] ,' </div> '; $comment_count++; // Finding all of the comment replies if any $search_for_article = mysql_query("SELECT * FROM article_comments WHERE article_id = '$article_to_show_id' AND reply_id = '$row_comment[id]'"); while($row_two = mysql_fetch_array($search_for_article)) { // format the submit updat date right $comment_date_edit = $row_two[comment_date]; $comment_date_edit = date('F j, Y \a\t h:ia', $comment_date_edit); $row_two[comment_date] = $comment_date_edit; echo ' <br> <br> COMMENT REPLY:<br> <div> By: ', $row_two[username] ,' on ', $row_two[comment_date] ,' </div> <div> ', $row_two[comment] ,' </div> '; $comment_reply_count++; } } Need some help I have 2 tables in a database and I need to search the first table and use the results from that search, to search another table, can this be done? and if it can how would you recommend that I go about it? Thanks For Your Help Guys! Hey guys, I've heard about MySQL being replaced with PDO some time in the future, but as a simple question, I'm coding a personal website for my use only, would I still be able to use MySQL rather than changing it to PDO and learning that?
Its not going to be anything big or nothing just to keep me active in my spare time.
Thanks for you help.
Hi Chaps, I've got something of a mixed bag, in which I need some help with a MySQL query and PHP to display the results correctly. I'm basically after the following: Query to produce results of; invoice_item_price of all jobs that include a Typesetting task and all of those that don't. The problem I'm having is that I can't figure out how to get the correct SUMtotal of the invoice_item_price, when searching through the tbl_task_item, to see if a Typesetting task has been completed. In trying to do this, it multiplies the invoice_item_price by the amount of tasks within a job.

But again, becoming a bit stuck in getting this to work too. <table border="3" cellpadding="3" cellspacing="3"> <tr> <td>Month</td> <td>Year</td> <td>JobType</td> <td>Analysis Net</td> <td>Analysis Gross</td> <td>Pages</td> <td>Invoice Total</td> <td>Language</td> </tr> <?php $previousMonth = ''; $previousType = ''; do { if ($previousMonth != $row_rsProjType['the_month']) { //if ($previousType != $row_rsProjType['JobType']) {?> <tr> <td><?php echo $row_rsProjType['the_month']; ?></td> <td><?php echo $row_rsProjType['the_year']; ?></td> <td></td> <td></td> <td></td> <td></td> <td></td> <td></td> </tr> <?php $previousMonth = $row_rsProjType['the_month'];} ?> <tr> <td></td> <td></td> <td><?php echo $row_rsProjType['JobType']; ?></td> <td></td> <td></td> <td></td> <td></td> <td></td> </tr> <?php //$previousType = $row_rsProjType['JobType'];} ?> <tr> <td></td> <td></td> <td></td> <td><?php echo $row_rsProjType['analysis_net']; ?></td> <td><?php echo $row_rsProjType['analysis_gross']; ?></td> <td><?php echo $row_rsProjType['job_pages']; ?></td> <td><?php echo $row_rsProjType['total']; ?></td> <td><?php echo $row_rsProjType['langname']; ?></td> </tr> <?php } while ($row_rsProjType = mysql_fetch_assoc($rsProjType)); ?> </table> If anyone can help me out in getting this to display correctly, it'll be highly appreciated. Not sure if this is the correct place to ask this question but here we go. I just wanted to know if I could insert into a MySQL database table a PHP conditional statement. I mean I am able to add this data to the table but when I grab that info from the table and echo it out to the browser it does not get displayed correctly. What I am trying to do is add a small login form into the table and render it out but I see the acutal code instead of the form. If I removed all PHP code the form will render correctly. So I was thinking either I cant add PHP or I am doing it wrong. hello every one

hello i am making a online cook for people to register and make and online cookbook on there account i want them to be able to add recipes and be able to see them on there file, i know how it would connect to the database and how to send the information but what tables would i use and what fields? this is my basic site now www.lachlanmcgrath.net, if you can help please reply here or even e-mail me at lmcgr44@me.com thank-you for your help Umm.. Yeah, this MySQL line needs some reviewing list($total_banned_servers) = mysql_fetch_row(mysql_query("SELECT COUNT(id) FROM `toplist` WHERE banned='1' && serverowner=". $_SESSION['user'] ."")); in php you have the following mysql API fetch commands: ■mysql_fetch_array — Fetch a result row as an associative array, a numeric array, or both ■mysql_fetch_assoc — Fetch a result row as an associative array ■mysql_fetch_field — Get column information from a result and return as an object ■mysql_fetch_lengths — Get the length of each output in a result ■mysql_fetch_object — Fetch a result row as an object ■mysql_fetch_row — Get a result row as an enumerated array If u use one of them for example i use mysql_fetch_object. Code: [Select] $run = mysql_query(SELECT `status` FROM `[settings]` WHERE `name`= *); $display = mysql_fetch_object($run); other example Code: [Select] $run = mysql_query(SELECT `status` FROM `[settings]` WHERE `name`= 'abusing' AND `name`= 'hacking' AND `name`= 'cracking'); $display = mysql_fetch_object($run); When i do Code: [Select] $display->somethingIt wil assign the SELECT condition i want to assign the WHERE condition. the value of it. like i want to do this Code: [Select] $display->WHERE->hackinghow to do this? Hi All, I inherited some code as part of a bought website, I am trying to convert it to make it better and add functionality... however I am having a hard time trying to figure out what is going on in one particular section of code. In short there is basically a block of PHP which is producing a SQL statement, but the SQL always returns 0 results. I can't figure out why this is because I can't figure out what the PHP is producing. Would someone with my knowledge than me be kind enough to take a look and advise me where possible? This is the part doing the generating: Code: [Select] // IF THE CATEGORY FIELD IS NOT EMPTY if (!empty($row['category'])) { // EXPLODE THE ARRAY ON , $strArr = explode(",",$row['category']); // FOR EACH ONE for($i=0; $i<sizeof($strArr); $i++) { $str = trim($strArr[$i]); $strs .= "'".trim($strArr[$i])."',"; $sch[] = "category LIKE '%$str%'"; } echo "Categories in the array a ". $strs; echo "<br /><br />"; $strs = substr($strs,0,-1); $sch[] = "category in ($strs)"; } // IF THE SUBCOUNTY FIELD IS NOT EMPTY if(!empty($row['subcounty'])) { // EXPLODE THE ARRAY ON , $strArr = explode(",",$row['subcounty']); // FOR EACH ONE for($i=0; $i<sizeof($strArr); $i++) { $str = trim($strArr[$i]); $strs2 .= "'".trim($strArr[$i])."',"; $sch[] = "subcounty LIKE '%$str%'"; } echo "SubCounties in the array a ". $strs2; echo "<br /><br />"; $strs2 = substr($strs2,0,-1); $sch[] = "subcounty in ($strs2)"; } // IF THE TITLE FIELD IS NOT EMPTY if(!empty($row['title'])) { // JOIN SEARCH TERM TO THE ARRAY $sch[] = "(position LIKE '%$row[title]%' || description LIKE '%$row[title]%')"; echo "The title is: ".$row['title']; echo "<br /><br />"; } And this is the SQL part that always returns blank: Code: [Select] // COUNT THE AMOUNT OF RESULTS THEN SELECT THE JOBS FROM THE DATABASE $result = mysql_query("SELECT count(*) FROM jobs ". (($sch)?"WHERE ".join(" AND ", $sch):"").""); $total = mysql_result($result, 0); $r9 = mysql_query("SELECT * FROM jobs ".(($sch)?"WHERE ".join(" and ", $sch):"")." ORDER BY jobid DESC"); echo "The count is: " . $total; echo "<br /><br />"; Any help would be appreciated, Many thanks, Greens85 I have been trying very hard to get this script to work but I am no good at arrays... Anyhow, the basic idea is that the script will read an RSS feed and post all that content to the database which will be used to display content on the site. <?php $doc = new DOMDocument(); $doc->load('http://newsrss.bbc.co.uk/rss/sportonline_uk_edition/football/rss.xml'); $arrFeeds = array(); foreach ($doc->getElementsByTagName('item') as $node) { $itemRSS = array ( 'title' => $node->getElementsByTagName('title')->item(0)->nodeValue, 'desc' => $node->getElementsByTagName('description')->item(0)->nodeValue, 'link' => $node->getElementsByTagName('link')->item(0)->nodeValue, 'date' => $node->getElementsByTagName('pubDate')->item(0)->nodeValue ); array_push($arrFeeds, $itemRSS); } include 'dbconnect.php'; foreach ($arrFeeds as $item) { $sql="INSERT INTO tb_rss (title, desc, link, date) VALUES ($item => title), $item => desc, $item => link, $item => date)"; if (!mysql_query($sql)){ die('Error: ' . mysql_error()); } } ?> Current error messege is: Code: [Select] Error: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'desc, link, date) VALUES (Array => title), Array => desc, Array => link, Array =' at line 1 Help please? |
