i have reviewed code , found have not storing options in first page , when trying post on next page become 0 because radio button have same name , when post on next page post selected radio value.
for fulfill requirement need use below code first page:
<?php $random = rand(4, 5); $random2 = rand(1, 12); $random3 = rand(1, 60); $random4 = rand(1, 60); $random5 = rand(1, 60); if ($random2 % 4 != 0) { $random2 += 4 - ($random2 % 4); $call = $random; } else { $random2 += 4 - ($random2 % 4); $call = $random2; } $answer = $random * $random2; ?> <html> <head> <meta charset="utf-8"> <meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=1, user-scalable=no"> <link rel="stylesheet" href="css/main.css" type="text/css"/> <link rel="stylesheet" href="css/easy2.css" type="text/css"/> <title> easy game 2 </title> <center> <h1> easy game 2 </h1> <h2> multiple choice! </h2> <div class="border_solid"> <div id="timer"></div> </div> <hr> </center> </head> <body> <form method="post" action="doeasygame2.php"> <table cellspacing="40" class="table"> <tr> <td> <label for="question_1"><?php echo $random; ?> x <?php echo $random2; ?> =?</label> <input type="radio" id="mcq" name="mcq" value="<?php echo $random3; ?>"><?php echo $random3; ?> <input type="radio" id="mcq" name="mcq" value="<?php echo $random4; ?>"><?php echo $random4; ?> <input type="radio" id="mcq" name="mcq" value="<?php echo $random5; ?>"><?php echo $random5; ?> <input type="radio" id="mcq" name="mcq" value="<?php echo $answer; ?>"><?php echo $answer; ?> </td> <td> <input type="submit" class="submit" value="submit" name="submit"/><br> </td> </tr> </table> <input type="hidden" name="random" value="<?php print $random ?>"> <input type="hidden" name="random2" value="<?php print $random2 ?>"> <input type="hidden" name="random3" value="<?php print $random3 ?>"> <input type="hidden" name="random4" value="<?php print $random4 ?>"> <input type="hidden" name="random5" value="<?php print $random5 ?>"> <input type="hidden" name="answer" value="<?php print $answer ?>"> </form> </body> <script type="text/javascript"> var myvar = setinterval(function () { mytimer() }, 1000); var d = 0; function mytimer() { document.getelementbyid("timer").innerhtml = d++; } </script> </html> please use below code second page:
