<?php 

    //get the value of all the needed information 
    $student_sql = mysql_query("SELECT * FROM students WHERE student_id='$_SESSION[student]' LIMIT 1"); 
    while($s = mysql_fetch_array($student_sql)) { 
     $fname = $s["first_name"]; 
     $lname = $s["last_name"]; 
     $_SESSION['first_name'] = $fname; 

    } 
    $question_sql = mysql_query("SELECT * FROM questionnaire WHERE questionnaire_id='$_SESSION[questionnaire]'"); 
    while($q = mysql_fetch_array($question_sql)) { 
     $total = $q["questionnaire_total"]; 
    } 
    $cat_sql = mysql_query("SELECT * FROM question WHERE category_id='$_SESSION[question]'"); 
    while($y = mysql_fetch_array($cat_sql)) { 
    $cate = $y["category_id"]; 
     } 

    define("NL","<br>\n");

         ?> 

         <input name="submit" type="submit" class="btn btn-success" value="Continue">

Answer 1

使用JavaScript才達到它：

window.setTimeout(function(event) { 
    $('form').submit(); 
}, 1000); 

$('form').on('submit', function(event){ 
    event.preventDefault(); 
    alert('submited') 
}) 

這裏舉例： http://jsfiddle.net/DariuszMusielak/3pkmb49x/1/
