PHP - How To Display Number Of Correct Answers
On my application there is 10 math questions. What I want to do when the test is finished is for it to tell the user how many they got right out of 10. Also how to put this into the database. I have everything else working fine on this application, I just would like to further enhance it by doing this.
This is the code to my application. It is a small application. Code: [Select] <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>Multiplication Test</title> </head> <body> </body> <?php require_once('database.php'); session_start(); define ('ROWS', 2); define ('COLS', 5); define ('MAX_NUMBER', 12); date_default_timezone_set('America/New_York'); if (isset($_POST['btn_score'])) { $result_name= $_POST['result_name']; $correct = 0; //print_r ($_POST); $time1 = $_POST['ts']; $time1_object = new DateTime($time1); $now = new DateTime(); $time_span = $now->diff($time1_object); $minutes = $time_span->format('%i'); $seconds = $time_span->format('%s'); $seconds+= $minutes * 60; echo "It took $seconds seconds to complete the test<hr />"; foreach ($_POST as $problem => $answer) { if ($problem <> "btn_score" && $problem <> "ts" && $problem <> "result_name") { //echo "$problem -- $answer <br />"; $problem = explode('_', $problem); $num1 = $problem[2]; $num2 = $problem[3]; $right = $num1 * $num2; if ($answer != $right) { echo "$num1 * $num2 = $answer , The right answer is $right<br />"; }else { $correct = $correct + 1; } } } $result_score= 0; $result_score= ($correct / 10) * 100; echo "your score is <br/>$result_score<br/>"; } { $sql = "INSERT INTO results (result_name, result_score, result_date_time) VALUES ('$result_name','$result_score', NOW());"; $db->exec($sql); } $query = "SELECT * FROM results WHERE result_name = :result_name "; $statement = $db->prepare($query); $statement->bindValue (':result_name', $result_name); $statement->execute(); $results = $statement->fetchAll(); $statement->closeCursor(); echo "<h1>Show Grades for $result_name </h1>"; foreach ($results as $result) { echo $result['result_name'] .

I know the last 4 can be obtained as follows: Code: [Select] $number=substr($number,-4,4); But when i hit the submit button the form validates the input field and checks if the number is a valid number of a specific format. Therefore when I click on the submit button then I should still be able to unmask the masked numbers or do something similar that would help me validate the whole number. Code: [Select] <input type="text" name="no" value="<?php if(!empty($number)){ echo $number;} ?>"> This topic has been moved to MySQL Help. http://www.phpfreaks.com/forums/index.php?topic=311502.0 Hello, I currently have a .txt file with numbers, and I want PHP to display the number closest to 1000. What method would I use to go about doing this? Thanks Hi, I am new to PHP and I have this homework due Sunday, I got it on Friday btw I have complete the first part of it , but I can not complete the second part of it. This is the exercise: Largest Row and Column Write a 4x4 array and fill it with random 1's or 0's 0 0 1 1 0 1 0 0 1 0 1 1 1 0 0 1 Display which row and which column has the biggest number of 1's this is my code:
<?php
$num = array("0", "1");
$rows = rand(4, 4); //using rand() function to generate 4 different numbers, min & max=4

[edit : zane] Don't hesitate to use code tags next time ;), it's the <> button. When displaying data from a mysql table, what php code can I use to display the number of columns in said table?

Basically another program manages a bunch of images, but this script displays certain ones (ones with INCLUDE = 1 in the database) on my main page. My question is, is there an easy way to limit the number of images it displays, say to 5? I'm not too concerned which images actually display (ascending or descending)... or better yet, random! Most importantly, I only want five to display. Each image will be linked to the full page, which displays all the images. Any ideas? Thanks!

I may want to choose 17 or whatever etc, not sure how to add it into the php. I'm getting the dreaded " Invalid parameter number: number of bound variables does not match number of tokens" error and I've looked at this for days. Here is what my table looks like:
| id | int(4) | NO | PRI | NULL | auto_increment | | user_id | int(4) | NO | | NULL | | | recipient | varchar(30) | NO | | NULL | | | subject | varchar(25) | YES | | NULL | | | cc_email | varchar(30) | YES | | NULL | | | reply | varchar(20) | YES | | NULL | | | location | varchar(50) | YES | | NULL | | | stationery | varchar(40) | YES | | NULL | | | ink_color | varchar(12) | YES | | NULL | | | fontchosen | varchar(30) | YES | | NULL | | | message | varchar(500) | NO | | NULL | | | attachment | varchar(40) | YES | | NULL | | | messageDate | datetime | YES | | NULL |Here are my params:
$params = array(
':user_id' => $userid,
':recipient' => $this->message_vars['recipient'],
':subject' => $this->message_vars['subject'],
':cc_email' => $this->message_vars['cc_email'],
':reply' => $this->message_vars['reply'],
':location' => $this->message_vars['location'],
':stationery' => $this->message_vars['stationery'],
':ink_color' => $this->message_vars['ink_color'],
':fontchosen' => $this->message_vars['fontchosen'],
':message' => $messageInput,
':attachment' => $this->message_vars['attachment'],
':messageDate' => $date );
Here is my sql:
$sql = "INSERT INTO messages (user_id,recipient, subject, cc_email, reply, location,stationery, ink_color, fontchosen, message,attachment) VALUES( $userid, :recipient, :subject, :cc_email, :reply, :location, :stationery, :ink_color, :fontchosen, $messageInput, :attachment, $date);";
And lastly, here is how I am calling it:
$dbh = parent::$dbh;
$dbh->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_WARNING);
if (empty($dbh)) return false;
$stmt = $dbh->prepare($sql);
$stmt->execute($params) or die(print_r($stmt->errorInfo(), true));
if (!$stmt) { print_r($dbh->errorInfo()); }
I know my userid is valid and and the date is set above (I've echo'd these out to make sure). Since the id is auto_increment, I do not put that in my sql (though I've tried that too), nor in my params (tried that too). What am I missing? I feel certain it is something small, but I have spent days checking commas, semi-colons and spelling. Can anyone see what I'm doing wrong?
It's pretty simple to see what I am trying to do here. For some reason all results in the table are the same exact cityName replacing all existing records. The echoed results are correct. I've include a small dump of my table as well. $query = "SELECT cityName FROM sys_city_dev_2"; $resource = mysqli_query($cxn, $query) or die("MySQL error: " . mysqli_error($cxn) . "<hr>\nQuery: $query"); while($result = mysqli_fetch_assoc($resource)) { $nox = $result['cityName']; $toUpper = ucfirst($nox); echo "$toUpper" . "<br />"; $setString = "UPDATE sys_city_dev_2 SET cityName = '" . $toUpper ."' WHERE cityName != ''"; mysqli_query($cxn,$setString); } 100 Records of table dump (pre running my script above): -- -- Table structure for table `sys_city_dev_2_backup` -- CREATE TABLE IF NOT EXISTS `sys_city_dev_2_backup` ( `ID` int(11) NOT NULL AUTO_INCREMENT, `Mid` int(11) NOT NULL DEFAULT '0', `cityName` varchar(30) NOT NULL DEFAULT '', `forder` int(4) NOT NULL DEFAULT '0', `disdplay` int(4) NOT NULL DEFAULT '0', `cid` int(11) NOT NULL DEFAULT '0', PRIMARY KEY (`ID`) ) ENGINE=MyISAM DEFAULT CHARSET=latin1 AUTO_INCREMENT=113970 ; -- -- Dumping data for table `sys_city_dev_2_backup` -- INSERT INTO `sys_city_dev_2_backup` (`ID`, `Mid`, `cityName`, `forder`, `disdplay`, `cid`) VALUES (84010, 1, 'dothan', 0, 0, 0), (84011, 1, 'alabaster', 0, 0, 0), (84012, 1, 'birmingham', 0, 0, 0), (84013, 2, 'flagstaff', 0, 0, 0), (84014, 1, 'auburn', 0, 0, 0), (84015, 1, 'florence', 0, 0, 0), (84016, 1, 'gadsden', 0, 0, 0), (84017, 1, 'huntsville', 0, 0, 0), (84018, 1, 'mobile', 0, 0, 0), (84019, 1, 'montgomery', 0, 0, 0), (84020, 1, 'tuscaloosa', 0, 0, 0), (84021, 2, 'mohave valley', 0, 0, 0), (84022, 2, 'phoenix', 0, 0, 0), (84023, 2, 'prescott', 0, 0, 0), (84024, 2, 'sierra vista', 0, 0, 0), (84025, 2, 'tucson', 0, 0, 0), (84026, 2, 'yuma', 0, 0, 0), (84027, 3, 'bakersfield', 0, 0, 0), (84028, 3, 'chico', 0, 0, 0), (84029, 3, 'fresno / madera', 0, 0, 0), (84030, 3, 'gold country', 0, 0, 0), (84031, 3, 'humboldt county', 0, 0, 0), (84032, 3, 'imperial', 0, 0, 0), (84033, 3, 'inland empire', 0, 0, 0), (84034, 3, 'los angeles', 0, 0, 0), (84035, 3, 'alhambra', 0, 0, 0), (84036, 3, 'merced', 0, 0, 0), (84037, 49, 'fayetteville', 0, 0, 0), (84038, 49, 'fort smith', 0, 0, 0), (84039, 49, 'jonesboro', 0, 0, 0), (84040, 49, 'little rock', 0, 0, 0), (84041, 49, 'arkadelphia', 0, 0, 0), (84042, 49, 'texarkana', 0, 0, 0), (84043, 3, 'modesto', 0, 0, 0), (84044, 3, 'alta sierra', 0, 0, 0), (84045, 3, 'alpine', 0, 0, 0), (84046, 3, 'pedley', 0, 0, 0), (84047, 3, 'redding', 0, 0, 0), (84048, 3, 'alondra park', 0, 0, 0), (84049, 3, 'sacramento', 0, 0, 0), (84050, 4, 'canon city', 0, 0, 0), (84051, 3, 'san luis obispo', 0, 0, 0), (84052, 3, 'santa barbara', 0, 0, 0), (84053, 3, 'stockton', 0, 0, 0), (84054, 3, 'aliso viejo', 0, 0, 0), (84055, 3, 'visalia', 0, 0, 0), (84056, 3, 'yuba city', 0, 0, 0), (84057, 4, 'boulder', 0, 0, 0), (84058, 4, 'colorado springs', 0, 0, 0), (84059, 4, 'denver', 0, 0, 0), (84060, 4, 'applewood', 0, 0, 0), (84061, 4, 'pueblo', 0, 0, 0), (84062, 4, 'air force academy', 0, 0, 0), (84063, 5, 'avon', 0, 0, 0), (84064, 5, 'hartford', 0, 0, 0), (84065, 5, 'new haven', 0, 0, 0), (84066, 5, 'ansonia', 0, 0, 0), (84067, 5, 'fairfield', 0, 0, 0), (84068, 7, 'daytona beach', 0, 0, 0), (84069, 7, 'sebastian', 0, 0, 0), (84070, 5, 'wallingford center', 0, 0, 0), (84071, 8, 'belvedere park', 0, 0, 0), (84072, 7, 'sarasota springs', 0, 0, 0), (84073, 7, 'sandalfoot cove', 0, 0, 0), (84074, 7, 'san carlos park', 0, 0, 0), (84075, 7, 'st. augustine', 0, 0, 0), (84076, 7, 'tallahassee', 0, 0, 0), (84077, 7, 'safety harbor', 0, 0, 0), (84078, 7, 'ruskin', 0, 0, 0), (84079, 8, 'athens-clarke county', 0, 0, 0), (84080, 8, 'atlanta', 0, 0, 0), (84081, 8, 'augusta-richmond county', 0, 0, 0), (84082, 8, 'brunswick', 0, 0, 0), (84083, 8, 'columbus', 0, 0, 0), (84084, 8, 'americus', 0, 0, 0), (84085, 8, 'acworth', 0, 0, 0), (84086, 8, 'valdosta', 0, 0, 0), (84087, 10, 'boise', 0, 0, 0), (84088, 10, 'ammon', 0, 0, 0), (84089, 10, 'moscow', 0, 0, 0), (84090, 10, 'blackfoot', 0, 0, 0), (84091, 10, 'twin falls', 0, 0, 0), (84092, 10, 'meridian', 0, 0, 0), (84093, 10, 'jerome', 0, 0, 0), (84094, 10, 'idaho falls', 0, 0, 0), (84095, 11, 'addison', 0, 0, 0), (84096, 10, 'garden city', 0, 0, 0), (84097, 10, 'eagle', 0, 0, 0), (84098, 10, 'chubbuck', 0, 0, 0), (84099, 10, 'caldwell', 0, 0, 0), (84100, 12, 'bloomington', 0, 0, 0), (84101, 12, 'evansville', 0, 0, 0), (84102, 12, 'fort wayne', 0, 0, 0), (84103, 12, 'indianapolis', 0, 0, 0), (84104, 12, 'muncie / anderson', 0, 0, 0), (84105, 12, 'lafayette / west lafayette', 0, 0, 0), (84106, 12, 'south bend / michiana', 0, 0, 0), (84107, 12, 'terre haute', 0, 0, 0), (84108, 12, 'northwest indiana', 0, 0, 0), (84109, 13, 'ames', 0, 0, 0); Right now my application only displays the answers and problems when the user hits the score button.

Basic question and answer problem, where I am developing a website that uses Items and questions like " How many of this Item do you need?" the answer seems to simple. Lets say the answer Is "1". The display is given to the Item list and we move on. Here is the Problem: When selecting Muiltiple Items in the List and they all have the same question associated to each Item: "How Many Items do you need?" the the answer is shared between the Items, Again, sounds simple so far, However, when the USER selects Multiple Items on a list say 30 Items then the Question should only be dispalyed one time, not 30 times, then the answer is shared 30 times. Thats what I have now being displayed on my website, 30 of the same questions over and over again. The USER will get frustrated and leave the site never to return. Question: How can I get the Question to be displayed only once, but shared between several items on a list? This is a very serious problem fo my website because I will have not have just one Item on a list but 300 to 400 items, and if I get the answer to the problem I have just wasted 1 year of my life developing something undevelopable (is that a word?). Any Help you can give me would greatly be appricated. Thank you in advance. What I'm trying to do is have it select the answers that are associated to that poll so that I can make a poll form out of this. Code: [Select] function getpoll($dbc) { $query = " SELECT polls.ID, polls.question, polls.totalVotes, (SELECT pollAnswers.ID, pollAnswers.answer FROM pollAnswers WHERE pollAnswers.pollID = polls.ID) FROM polls INNER JOIN pollAnswers ON polls.ID = pollAnswers.pollID WHERE polls.statusID = '1' ORDER BY polls.ID DESC LIMIT 1"; $result = mysqli_query($dbc, $query); $numrows = mysqli_num_rows($result); if ($numrows > "0") { } else { print "<p class=none>There are currently no open polls."; } } Hi Everyone, I will have a web application that users fill out and submit. I also have the same form in PDF format. I would like users to be able to click a print preview button, then open up FoxIt or Adobe and display the PDF, with their answers mapped to the correct location. I have no code, just looking for a direction and didn't know what to search for. Thanks. I've just learned the basics of MySQL last night and made a simple app (where a user enters a song name, song title, and rating (out of 5) and it displays the list of songs with the highest rated songs first). So I decided I wanted to make something similar yet slightly more complicated and I'm not sure if I'm on the right track. Basically it's a "flash card" game whe - The user gets to input their own questions and answers into a simple form, which would then go into an MySQL table with 2 columns, questions and answers - A new page where the user see's random question, must input an answer, if the answer matches goes to next question otherwise gives error Now I'm confused as to how to go about making this. I was thinking of making some session variables and then do something along the lines of Code: [Select] $display_query = "SELECT * FROM questions"; $display = mysqli_query($connection, $display_query); while ($row = mysqli_fetch_array($display)) { $_SESSION['question'] = $row[0]; }[/syntax] //and then make some PHP that might do something like this: if ($_SESSION['answer'] != $row[1]) { echo "error, try again" } else { // I would write something here to grab the next question } So am I just completely off the wall with this, how would I make such an app? How would I make it, for example, fetch new questions? Hi, I have a job listing website which displays the closing date of applications using: $expired_date (This displays a date such as 31st December 2019) I am trying to show a countdown/number of days left until the closing date. I have put this together, but I can't get it to show the number of days.
<?php
$expired_date = get_post_meta( $post->ID, '_job_expires', true );
$hide_expiration = get_post_meta( $post->ID, '_hide_expiration', true );
if(empty($hide_expiration )) {
if(!empty($expired_date)) { ?>
<span><?php echo date_i18n( get_option( 'date_format' ), strtotime( get_post_meta( $post->ID, '_job_expires', true ) ) ) ?></span>
<?php
$datetime1 = new DateTime($expired_date);
$datetime2 = date('d');
$interval = $datetime1->diff($datetime2);
echo $interval->d;
?>
<?php }
}
?>
