PHP - How Would I Create This App (fetching Questions & Answers From Mysql)
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'] != $row[1]) { echo "error, try again" } else { // I would write something here to grab the next question } So am I just completely off the wall with this, how would I make such an app? How would I make it, for example, fetch new questions? Similar TutorialsHi, I was wondering if any one can help me out with this little issue. I select some data, and put it on a while loop, so something like while($row = mysql_fetch_array($result)){ body } but at the very last element in the array I'd like to something a little different than else. So, i have 4 elements. For the first 3 I'd like to print element1, element2, element 3, element4 Notice the missing comma at element4 Can you add a WHERE clause in $row? For example: $row['city_display'] WHERE city_display = 1 $row['city_display'] WHERE city_display = 2 etc... How can this be done? hello, 2 questions 1, can i set the auto increment to start at 1400 instead of number 1? 2, if i have a field that is auto increment, can i insert a number into that field if i want also? for instance, the next auto number is 1420, but i want to use number 1200. thanks! Hello guys, i want to create array from mysql what is the script for this...? value like $data = array("1" => .0032, "2" => .0028, "3" => .0021, "4" => .0033, "5" => .0034, "6" => .0031, "7" => .0036, "8" => .0027, "9" => .0024, "10" => .0021, "11" => .0026, "12" => .0024, "13" => .0036, "14" => .0028, "15" => .0025); What I mean by dynamic is say I created a function to generate a random code. I put it in a variable named $key. I make a form with a hidden input type with the name and value of $key. When the form posts, it generates the table name to whatever $key is. Because I tried something like this & its not querying. Heres my code: <?php $dbc = mysqli_connect('localhost', 'cpacrop_todo', 'pass', 'cpacrop_todo') or die('Failed to connect to database!'); function make_key($num_chars) { if ((is_numeric($num_chars)) && ($num_chars > 0) && (! is_null($num_chars))) { $key = ''; $accepted_chars = 'ABCDEFGHIJKLMNOPQRSTUVWXYZ1234567890'; //seed srand(((int)((double)microtime()*1000003)) ); for ($i=0; $i<=$num_chars; $i++) { $random_number = rand(0, (strlen($accepted_chars) -1)); $key .= $accepted_chars[$random_number] ; } return $key; } } $key = make_key(6); ?> <form action="" method="post"> <input type="hidden" name="<?php echo "$key"; ?>" /> <input type="submit" name="submit" value="Submit" /> </form> <?php if ($_POST['submit'] == "Submit") { $query = "CREATE TABLE `$key` ( `id` INT AUTO_INCREMENT, `title` VARCHAR(35), `description` VARCHAR(365) );"; mysqli_query($dbc,$query) or die('Unable to query database.'); echo "Success"; } ?> If this is possible, what am I doing wrong? Thanks! I want to create a text file based blog ( not using MySQL or other databases). I have tried to google for tutorials but I couldn't find anything. is there anyone who can help me and give me some tips? is there any tutorials about this because I found nothing? Any good books?

I'm working on a new site idea and I've run across a problem that I know is simple enough but I'm stumped. It's in the signup form What I want to do is insert the new user into the 'Login' table and get the user id that was just created and use that to create a table with the user id in the name. Here is what I have: // now we insert user into 'Login' table mysql_real_escape_string($insert = "INSERT INTO `Login` (`UID`, `pass`, `HR`, `mail`, `FullName`) VALUES ('{$_POST['username']}', '{$_POST['pass']}', '{$_POST['pass2']}', '{$_POST['e-mail']}', '{$_POST['FullName']}')"); mysql_query($insert) or die( 'Query string: ' . $insert . '<br />Produced an error: ' . mysql_error() . '<br />' ); $error="Thank you, you have been registered."; setcookie('Errors', $error, time()+20); // Get user ID mysql_real_escape_string($checkID = "SELECT * FROM Login WHERE `mail` = '{$_POST['e-mail']}'"); while ($checkIDdata = mysql_fetch_assoc($checkID)) { $userID = $checkIDdata; // now we create table 'Transactions" for the user mysql_real_escape_string($create = "CREATE TABLE `financewatsonn`.`Transactions_{$userID}` ( `ID` INT( 20 ) NOT NULL AUTO_INCREMENT COMMENT 'Transaction ID', `name` VARCHAR( 50 ) NOT NULL COMMENT 'Name/Location', `amount` VARCHAR( 50 ) NOT NULL COMMENT 'Amount', `date` VARCHAR( 50 ) NOT NULL COMMENT 'Date', `category` VARCHAR( 50 ) DEFAULT NULL COMMENT 'Category', `delete` INT( 1 ) NOT NULL DEFAULT '0', UNIQUE KEY `ID` ( `ID` ) ) ENGINE = MYISAM DEFAULT CHARSET = utf8 COMMENT = 'User ID {$userID}'"); mysql_query($create) or die( 'Query string: ' . $create . '<br />Produced an error: ' . mysql_error() . '<br />' ); } I know in 'Get user ID' that I need to get the ID but I'm not sure how to get that information. i get the error Quote Warning: mysql_fetch_assoc(): supplied argument is not a valid MySQL result resource at 166 which is the while line under Get user ID i have two tables, employee details table(empno, emp_name , branch) and attendance table(date, Ot, attendence).

What method would I have to use? Hi to everybody I need ur help because I’m trying to make a script in php to write the same data but with different date in MySQL depending on the splitting ($data06).... like a schedule...
For example if $data06 = annual and $data03 = “2019/01/01” programm must create in MySQL : 2019/01/01 2020/01/01 2021/01/01 2022/01/01 2023/01/01
if $data06=“half year” will create 10 date , increasing 6 moths ...
But I have a problem at finish of code switch ($data06) { case 'annual': $numrate = 5; $aumdata = "+12 months"; break; case 'half year': $numrate = 10; $aumdata = "+6 month"; break;
default: echo "error"; $sql = "INSERT into $nometb ( name, scadenza ) values ( '$data01', '$data03' )"; if ($conna->query($sql) === TRUE) {} else {die('ERROR'. $conna->error); }
//IMPORT NEXT AND NEW DATE $newDate = date_create($data03); for ($mul = 2; $mul <= $numrate; ++$mul) {
$datanuova = date_create($data03); $datanuova->modify($aumdata); $datanuova->format('yy/m/d'); $newDate = $datanuova->format('yy/m/d');
$sql = "INSERT into $nometb ( name, scadenza ) values ( '$data01', '$newDate' )"; if ($conna->query($sql) === TRUE) {} else {die('ERROR'. $conna->error); }
//HERE THERE IS ERROR $data03 = $newDate;
if ($conna->query($sql) === TRUE) {} else {die('ERRORE NELL\'IMPORTAZIONE'. $conna->error); } }
} }
}
How I can resolve ?
many thanks Francesco I would like some tips on how to create a monthly archive for my weblog. I am not using MySQL or any databases. Everything is saved on file. any tips or tutorials? Thanks This topic has been moved to MySQL Help. http://www.phpfreaks.com/forums/index.php?topic=321735.0 Hi there, I hope somebody can help me creating a loop for the following code: What it currently does is, showing only 1 image, while in fact there are 3 of them. I've combined a loginsystem with slideviewer. When i use the original php code (or a part of it) it only shows one listing. I need it to list all of them. <div id="mygalone" class="svw"> <ul> <li> <?php $result = mysql_query("SELECT reference FROM user_photos WHERE`profile_id`='".$row['id']."'"); while ($row2 = mysql_fetch_array($result, MYSQL_ASSOC)) { echo "<a href=\"".$_GET['username']."/pics/".$row2['reference']."\"> <img src=\"".$_GET['username']."/pics/thumbs/".$row2['reference']."\"></a><br/><br/>"; } } ?> </li> </div> What can be stripped down to this: <?php { $result = mysql_query("SELECT reference FROM user_photos WHERE`profile_id`='".$row['id']."'"); while ($row2 = mysql_fetch_array($result, MYSQL_ASSOC)) { echo "<img src=\"".$_GET['username']."/pics/".$row2['reference']."\">"; } } ?> You would asume that this is allready a loop, but it does not act like it.
