PHP - On Browser Refresh/reload, Last Crud Operation Being Repeated - How To Reset/re-initialize That Behavior?
Hello All,
I've encountered one more problem (with the first WebApp I'm building), and I have no idea how to fix it. I've tried something, but it doesn't seem to work, so I'd appreciate some help in getting it fixed.
Here's what's happening:
So after I perform an operation (let's say "ADDing a record")...the records gets added correctly, but then, if/when I press [F5] in my browser window (or click on the Refresh/Reload icon), the same input details are being used and a second identical record is being added. I believe the same thing happens for some (or perhaps all) of the other CRUD operations.
What do I need to do to disable that behavior?
The only thing I could think of is to set the $functionSelected variable to blank ("") - which I've done towards the bottom of my code (shown below) - but that doesn't seem to be doing anything...the problem persists.
if(isset($_POST['action']))
{
$functionSelected = $_POST["action"];
}
if(isset($functionSelected)){
switch($functionSelected){
case "insert":
$initialize_flag = "N";
// Store POST(ed) user-entered values into memory variables
$store_name = $_POST['store_name'];
$item_description = $_POST['item_description'];
$qty_pkg = $_POST['qty_pkg'];
$pkg_of = $_POST['pkg_of'];
$price = $_POST['price'];
$flyer_page = $_POST['flyer_page'];
$limited_time_sale = $_POST['limited_time_sale'];
$flyer_date_start = $_POST['flyer_date_start'];
$nos_to_purchase = $_POST['nos_to_purchase'];
// Setup customized query
$sql = "INSERT INTO shoplist
(store_name, item_description, qty_pkg, pkg_of, price, flyer_page, limited_time_sale, flyer_date_start, nos_to_purchase, shopper1_buy_flag, shopper2_buy_flag, purchased_flag, purchase_later_flag)

try {
$statement = $conn->prepare($sql);
$statement->bindParam(':store_name', $store_name);
$statement->bindParam(':item_description', $item_description);
$statement->bindParam(':qty_pkg', $qty_pkg);
$statement->bindParam(':pkg_of', $pkg_of);
$statement->bindParam(':price', $price);

$statement->bindParam(':shopper2_buy_flag', $initialize_flag);
$statement->bindParam(':purchased_flag', $initialize_flag);
$statement->bindParam(':purchase_later_flag', $initialize_flag);
// Execute the query
$statement->execute();
$statement->closeCursor();
$functionSelected = ""; // WILL THIS STATEMENT NOT SERVE TO INITIALIZE/RESET THE OPERATION???
break;
} catch (PDOException $e) {
print "Error!: " . $e->getMessage() . "<br/>";

This problem happens in both IE9 and Chrome 13.0.782.112 m on Windows If I close the browser down, my session data is gone on browser restart, if however I just close the tab leaving other tabs say with BBC news and restart my app in a new tab, both browsers remember the old session data. Since the intended user could do this at any time before completing a transaction, I don't actually get a chance to destroy the session this only happens if they complete payment for their order via.. Code: [Select] session_destroy(); $conn->commit(); $conn->autocommit(TRUE); In an attempt to clean up I tried various combinations at the top of the start page "index.php".. Code: [Select] session_start(); // $_SESSION = array(); session_destroy($_SESSION['cart']); session_destroy($_SESSION['address']); // $_SESSION['cart'] = array(); // $_SESSION['address'] = array(); // session_destroy(); Can anyone please shed any light on this behaviour difference? Jamie Hello, guys. I'm using the following code to send me an automated mail in case the user find a broken link. But there are 2 problems: 1) after submitting I'd rather not disrupt their game by refreshing the page. So, is there any way to send mail without the post refreshing? 2) if the user hits F5, the page reloads and the code runs again, sending two or more times the same email. How can I avoid duplicated emails caused by manual browser refresh? (the most important solution currently is how to to avoid duplicated entries, in case an ajax solution is too hard to post here.) <form name="fbrlink" action="<?= $_SERVER['PHP_SELF']."?page=ok" ?>" method="post"> <?php echo('<input name="sbrlink" id="B1" type="button" value="broken Link?" style="border:none; background-color:#FFFFFF; font-family:Trebuchet MS; font-size:15px; font-weight:bold; color:#1A4877; cursor:pointer; display:block; text-decoration:underline;" onclick="this.form.submit();"/>'); ?> <?php if ($_SERVER['REQUEST_METHOD'] == 'POST') { if ($_SERVER['QUERY_STRING'] == 'page=ok') { echo '<script type="text/javascript" >confirm("Click OK to notify us.");</script>'; mail("contact@ctt.net","report broken link","Game notified:MarioBros"); echo '<script type="text/javascript" >document.fbrlink.sbrlink.disabled = true;</script>'; ?> <script type="text/javascript" >document.fbrlink.action='<?php echo $a; ?>'; alert('<?php $_SERVER['QUERY_STRING'];?>'); </script> <?php } else {} }else{ } ?> I need the following three variables to be available globally, that is to every page.

I am trying to create a customer tracking database that will allow me to get a handle on my customer support inquiries. To do this I have created a database that will store all of a customers pertinent information and then I plan on creating another table that will be 'Notes' where each note is associated with a customerID. I have created the form fine where I can input the data into the table but I am having issues with the next part. I would like to have a list/menu that will display all of the current users in the database. Then when I click on one of those it will display that information in the form so that I can view it, edit it, or delete it. But I have been stumped for multiple days and other php forums have been absolutely worthless. I know that php can pass a variable name in the address but I have no idea how to do that or how to use it when it's in the address. I know I'm a newb. Please help.

Jared Hey sorry that I am asking this question, though I have gotten around to learn connecting to a database and also do the retrieve, yet I am not necessarily getting to learn doing INSERT, UPDATE and DELETE the proper way.
The tutorials available are often not best, I have found a good book ("Object Oriented Programming in PHP5") which teaches SELECT, yet not necessarily INSERT, UPDATE and DELETE.
I am really wondering how does one get to learn CRUD with PHP OOP, how did you people learn this? How can I learn INSERT, UPDATE and DELETE as well with PHP OOP? I feel like paying for this on Elance or Fiverr. I am not sure how else to learn this by now, I have tried quite a bit, I have looked at scripts and tutorials and books. And it has just gotten as far as connecting to the database and doing the "fetching" ("SELECT", or also "retrieve"). Too bad that what is available is not necessarily best. Otherwise I would say one could understand the principle quickly and also pick up on a programming language quickly. Please bear with me, I would appreciate suggestions. This topic has been moved to Beta Test Your Stuff!. http://www.phpfreaks.com/forums/index.php?topic=307377.0 Hi all, iv benn search for a long time now for a sample on how to create MYSQL based data grid that have some CRUD functionality.. i am using dreamwever and the only thing i can get out of it is using the spray data set that gives me a table with sort abilities but i am looking for something more.. is there a PHP or JS sample of displying the data of MYSQL database that can can do CRUD and search abilities ? thank.. Hello! I need a while loop that renders out part of my "header" redirect block. <?php header ('Location: /mylocation?' /////this is where the header starts. however, for the rest of the header, it needs to be dynamic $counter=1; //I need to define some variables while (babababa) // and I need a while loop that renders out stuff for the header. { Renders out stuff for the header } ) // and then finally i close the "header" ?> However, apparently.. it's yelling at me for having dynamic stuff within the header. Parse error: syntax error, unexpected T_WHILE in /var/www/ars/includes/common.inc(1699) : eval()'d code on line 18 So.... how would I put something dynamic, like a while loop or variables, within the "header" redirect block? Thanks folks! Sorry if this is a bad question xD Hello everybody,
I want to obtain from the database the rows that have been inserted in the last seven days.
Every time that I insert a row, I add a date with this format:
$today = date("Y-m-d H:i:s");
So it should be like:
$lastweek = date("Y-m-((d)-7) H:i:s");
SELECT * FROM pub WHERE data BETWEEN('$today' AND '$lastweek')
Is it possible? which is the method to do that?
Thank you all
Hi, I am creating my first OOP MVC content management system. I created a CRUD where on the Tag view page, you click edit and it takes you to the Tag edit page. But I want to improve the user experience, so when a user clicks edit, a modal window displays allowing editing of Tag, upon clicking save, modal window closes and AJAX updates Tag view page without refresh.

If I add a form in the modal window with {{ tag.id }} and {{ tag.name }}, nothing displays obviously because it is not in the for in loop. My question is, what is the industry standard way of getting data into this modal window form? I could use a $_GET["id"] but then I am breaking MVC model by including code in template. Is the solution to use JavaScript to get ID from edit link, in the background get data from database then use JavaScript to create form in modal? Your help would be much appreciated! how do you use a while loop 2 twice from one assoc array? eg <tr> <td>1st favourite</td> <td><select name = 'fav_1'>"; while($Cat = mysql_fetch_assoc($rCat)) { echo " <option value='{$Cat['catID']}'>{$Cat['categorys']}</option>";} echo "</td> </tr> <tr> <td>2nd favourite</td> <td><select name = 'fav_2'>"; while($Cat = mysql_fetch_assoc($rCat)) { echo " <option value='{$Cat['catID']}'>{$Cat['categorys']}</option>";} echo "</td> </tr> The first one works fine but the second is empty. Hello my good people
I'm doing a content manager system in PHP and mySQLi, following a serie of video tutorials.
But in my project I am using a tree menu.
In the front office all works smoothly (the tree menu displays all results - menu and submenus - and each button carries the information of the respective page). <?php require_once('upper.php'); require_once('database.php'); require_once('LoginStatement.php'); $LoginId=$_COOKIE['LoginIdCookie']; $query="select * from activity_participation where LoginId='$LoginId'"; $result=mysqli_query($dbc,$query) or die ('Not Connected'); //echo "<div class='search_output_data'> echo "<table border='0' cellspacing='0' cellpadding='0'>"; while($row=mysqli_fetch_array($result)) { echo "<tr><th align='left' valign='top'>Activity Title</th> <th align='left' valign='top'>Date of Participation</th> </tr> <tr><td colspan='4' align='left' valign='top'><table align='left' border='0' cellspacing='0' cellpadding='0'><tr><td align='left' valign='top'>".$row['Title']."</td> <td align='left' valign='top'>".$row['Date']."</td> </tr></table> </td></tr>"; } echo "</table>"; //echo "</div>"; require_once('lower.php'); ?>In table activity_participation many rows have same values. I want to display only different rows to user not to display same rows again and again. Or Anybody have idea to prevent the row duplication in database.... Help me please......... thanks in advance............. I've played around with CakePHP, then XCrud (a decent CRUD application) but I gave up on both of them, XCrud was great for everything up until it came to managing complicated relational database tables. Anyhow, I'm using wordpress a lot now cuz it lets me stop reinventing the wheel so much and although I was able to integrate XCrud into WordPress as a plugin, I think the best way to go is just transfer my database tables to WordPress tables and display them as custom post types. My time is really limited right now though, is there a plugin/set of plugins I can use to automate the process? To show you what I mean, heres the XCrud list display of one of the tables:
thats great because it automatically sets up the CRUD thing and lets you add and edit fields to the table, and doesn't heavily box you into their system but I have a table of plants, one for products, one for pharmacology, one for categories which are all related to each other, and some of them are structured in a tree/nested hierarchy structure so long story short, I need to do advanced searches based on these relations and handle these tree structured tables and CakePHP didn't work out, and XCrud has crappy documentation and isn't popular enough to find good info.
So how would you go about transfering this system to WordPress? I'm guessing I need to make custom post types for each table but what I don't yet know is how to transfer the DB tables to WordPress format, how to handle the relationships between each table and how to handle the hierarchical tree structures.
Hi
I just finished this tutorial('http://www.startutor...torial-part-3/)
and everything was working fine until I decided to add last names to the application.
I got everything working on all the other pages except the Update page.
This is my php code.
Hi,
please help me to solve my query... I was incurring a problem in executing a PHP code which executes 'n' number of data sets..
For example -- in the below shown outputs, I need to eliminate executing the 4th output which is similar (repeated data) to the 1st output,
input output
4,4,5,6,5 4,4,5,5,6
4,4,5,7,5 4,4,5,5,7
4,4,5,7,6 4,4,5,6,7
4,4,6,5,5 4,4,5,5,6
Kindly send me the function details to execute it without repetition.
Thanks a lot for your support!
Regards,
Maanu
