PHP - How Do I Return A Error?
Say I have my login form which then when person tries to log in with the wrong user name and password and sent straight back to the log in page, how do I send back they got the password and/or username wrong.
I read somewhere in some code header("location: index.php&$errorvariable"); or something like that. I haven't tested it, not even sure how to get it to work on the index, would I just use an isset on a get/post to check if it exists then echo the error? Similar TutorialsI have a form that worked fine on my personal server, but then when I tried it on another server, it is giving me a Return Error: 4. I don't even know what that code means or why I am getting it. Can someone help me get rid of this stupid error code?!? Please? :-) Here is the link to the page with the error: http://midwestcreativeconsulting.com/jhrevell/add/ Click submit to see the error. Can anyone help me get rid of it? Here is my code : https://paiza.io/projects/SUiG5qp_wttfcrQn-0Mwew?language=php FYI -> [index.htm -> LineNo : 781 & 782] After successfully received payment response page return 404 error The form & CC-Avenue Payment Gateway Request page working good, after customer paid the response page return 404 error. How can i solve the error? Edited May 22, 2019 by aveevaI am a new developer, trying to figure out what causing a memory error. The code goes through registered appointments and depends on the service ID, I have to free a 45 minutes for another service to be booked. Now, once I book an appointment for any of the services that can have 45 minutes free spot, the website takes forever to load the hours but doesn't show them, instead I get this error A PHP Error was encountered Severity: Error Message: Maximum execution time of 120 seconds exceeded

Appreciate if you folks could pls. help me understand (and more importantly resolve) this very weird error:
Fatal error: Uncaught exception 'PDOException' with message 'SQLSTATE[42000]: Syntax error or access violation: 1064 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 'ASC, purchase_later_flag ASC, shopper1_buy_flag AS' at line 3' in /var/www/index.php:67 Stack trace: #0 /var/www/index.php(67): PDO->query('SELECT shoplist...') #1 {main} thrown in /var/www/index.php on line 67
Everything seems to work fine when/if I use the following SQL query (which can also be seen commented out in my code towards the end of this post) :
$sql = "SELECT shoplist.*, store_master.store_name, item_master.item_name FROM shoplist, store_master, item_master WHERE shoplist.store_id = store_master.store_id AND shoplist.item_id = item_master.item_id";However, the moment I change my query to the following, which essentially just includes/adds the ORDER BY clause, I receive the error quoted above: $sql = "SELECT shoplist.*, store_master.store_name, item_master.item_name FROM shoplist, store_master, item_master ORDER BY purchased_flag ASC, purchase_later_flag ASC, shopper1_buy_flag ASC, shopper2_buy_flag ASC, store_name ASC) WHERE shoplist.store_id = store_master.store_id AND shoplist.item_id = item_master.item_id";In googling for this error I came across posts that suggested using "ORDER BY FIND_IN_SET()" and "ORDER BY FIELD()"...both of which I tried with no success. Here's the portion of my code which seems to have a problem, and line # 67 is the 3rd from bottom (third last) statement in the code below: <?php
/*
$sql = "SELECT shoplist.*, store_master.store_name, item_master.item_name

*/
$sql = "SELECT shoplist.*, store_master.store_name, item_master.item_name
FROM shoplist, store_master, item_master
ORDER BY FIND_IN_SET(purchased_flag ASC,
purchase_later_flag ASC,
shopper1_buy_flag ASC,
shopper2_buy_flag ASC,
store_name ASC)
WHERE shoplist.store_id = store_master.store_id
AND shoplist.item_id = item_master.item_id";
$result = $pdo->query($sql);
// foreach ($pdo->query($sql) as $row) {
foreach ($result as $row) {
echo '<tr>';
print '<td><span class="filler-checkbox"><input type="checkbox" name="IDnumber[]" value="' . $row["idnumber"] . '" /></span></td>';

Thank you
Hello First of all i am very weak about OOP and classes in php. I am learning now but i stuck with very silly problem. My codes are below. <?php class myTestClass { function __construct() { $this->OldName("This is Old Name"); } function OldName($VeryOld) { if($VeryOld == "This is Old Name") $this->NewName(); else $VeryOld = "Something Wrong"; return $VeryOld; } function NewName() { echo "This is Brand New Name"; } } $i = new myTestClass(); ?> if i send value to OldName "This is Old Name" then codes works fine. But if i send "This is Old Nameeee" then does not appear anything. what i want to do is print "Something Wrong" text if i enter different value. I have no idea what return do and how it do? How to retrieve/print "Something Wrong"? i can do that with echo but i want to transfer result of return to another function. Really appreciate for any help/idea. If a user is on Page X, but not logged in, when they log in to my website, I want them to return back to Page X (in this example). To handle this, I am adding this code to the top of each webpage... Code: [Select] // Set current Script Name. $_SESSION['returnToPage'] = $_SERVER['SCRIPT_NAME']; And then as part of my Log In script I have... Code: [Select] // Redirect User. if (isset($_SESSION['returnToPage'])){ header("Location: " . BASE_URL . $_SESSION['returnToPage']); }else{ // Take user to Home Page. header("Location: " . BASE_URL . "index.php"); } What do you think about this approach? Thanks, Debbie Hey all. My site has a config database table that has a column showlogin to set whether or not login functionality is enabled. I'm playing around with MySQLi, Classes, and Returns. My return is always 1.

My name is Raoul Grosser, live in The Netherlands.
I'm a front/backend developer working with AngularJS and Bootstrap and Symphone2.
I've been writing PHP code for over 4 years now my focus is on opensource projects.
If you have any question, please let me know!
Where should I validate the return value?
In the function should I validate the value before returning it.
Or once the value has been returned, should I check it?
Is it really necessary to validate the return value?
Thank you.

Hi, I have setup my paypal payment method for a shopping cart on my site, all is well but in order for my server to flag an invoice as paid, the user must return to my website after paying and the query string in the url give the script the go ahead to mark it as paid which in turn alerts the appropriate department that its ok to source the order. ~The problem is, if the user for whatever reason skip the redirect back to my site, the invoice is remain 'unpaid' and has to be changed manually when the payment has been checked in the account. As you might imagine this is a bit of a problem because not only can it cause quite a delay, it also requires manually changing values which can lead to other problems. So if there is a better way i would appreciate the info, thanks a lot. I am trying make my code display different things depending on how many rows are returned This is my code Code: [Select] <?PHP include 'db_con.php'; $month = date("n"); $day = date("j"); $sql = mysql_query("SELECT * FROM table WHERE month = $month AND day = $day ")or die(mysql_error()); while($row = mysql_fetch_array($sql) ) if (mysql_fetch_array($row = 1 ) ) ///THIS IS AN ERROR BUT IF ONE ROW RETURNED THEN THIS { echo "ONE THING"; } elseif (mysql_fetch_array($row >1 ) )////IF > 1 ROW RETURNED THAN THIS { echo"TWO THINGS"; } else { echo "SOMETHING ELSE "; } ?> I have tried several variations of the above code but cannot get it to work. Thanks for any help anyone can give me. Hi all, I am kinda stuck on the return() statement in the php.net manual about control structures. (http://au.php.net/manual/en/function.return.php) All I see is notes on when not to use it and some scary examples with loads of foo and bar but, it's hard to find out when it would be nice to use it. At the moment i am thinking its another way of echo, but I bet that's wrong. If someone could enlighten me a bit on when return() is useful I would be very happy since i see it more often everyday. CHeers! By calling function two will it break the loop?; or do i have to echo what is returned? Code: [Select] functione one() { $getids = mysql_query("SELECT * FROM table"); while($row=mysql_fetch_assoc($getids); { $this->two(); } } function two() { return 'break;'; } Hi everyone for my end of studies projects I decided to do a little e-commerce problem on the filter ..
