this is my code...
How get the textbox array value to store in database...
<html>
<head>
<script type="text/javascript">
var max = 4; //highest number to go to
var currentIndex = 0;
function btnClick() {
if(currentIndex < max){
currentIndex++;
postClick();
}
}
function Previous(){
if(currentIndex>0){
currentIndex--;
postClick();
}
}
function postClick() {//whatever you want to happen goes here
var sahans = new Array();
sahans[currentIndex] == d;
var d = document.getElementById("div");
d.innerHTML = "<p><input type='text' name='name"+currentIndex+"[]'>";
d.innerHTML += "<p><input type='text' name='topic"+currentIndex+"[]'>";
document.getElementById("div").style.display = "";
}
</script>
</head>
<body>
<form id="form1">
<div>
<input type="button" value="Previous" onclick="Previous();" />
<input type="button" value="Next" onclick="btnClick();" />
<div id="div"></div>
</div>
</form>
</body>
</html>
JavaScript:
function store(form) {
var input = form.getElementsByTagName('input');
var myarray = Array();
for (var i = 0; i < input.length; i++) {
if (input[i].getAttribute('type') == 'text') {
myarray[input[i].getAttribute('name')] = input[i].value;
}
}
for (var i in myarray) {
alert(i + ': ' + myarray[i]);
}
}
HTML:
<form onsubmit="store(this); return false">
<p>
<input type="text" name="name" /><br />
<input type="text" name="topic" />
</p>
<p>
<input type="submit" value="Store in database" />
</p>
</form>
Edit:
Ok, now I made a full example with AJAX and the actual saving to the database. The AJAX call uses 'POST'. Simply fill in the number of fields that you want in the max variable.
JavaScript:
var max = 10;
var current = 0;
function goto(form, pos) {
current += pos;
form.prev.disabled = current <= 0;
form.next.disabled = current >= max - 1;
var fields = form.getElementsByTagName('fieldset');
for (var i = 0; i < fields.length; i++) fields[i].style.display = 'none';
fields[current].style.display = 'block';
form['name' + current].focus();
}
function store(form) {
var input = form.getElementsByTagName('input');
var data = '';
for (var i = 0; i < input.length; i++) {
if (input[i].getAttribute('type') == 'text')
data += '&' + input[i].getAttribute('name') + '=' + input[i].value;
}
data = encodeURI('n=' + max + data);
var xhr = window.XMLHttpRequest ? new XMLHttpRequest() : new ActiveXObject('Microsoft.XMLHTTP');
xhr.open('POST', 'store.php', true);
xhr.setRequestHeader('Content-type', 'application/x-www-form-urlencoded');
xhr.setRequestHeader('Content-length', data.length);
xhr.setRequestHeader('Connection', 'close');
xhr.onreadystatechange = function() {
if (this.readyState == 4 && this.status == 200) {
if (this.responseText != '')
alert(this.responseText);
else {
form.submit.value = 'Saved!';
setTimeout(function() { form.submit.value = 'Save to database' }, 500);
}
}
}
xhr.send(data);
}
window.onload = function() {
var form = document.forms[0];
var container = form.getElementsByTagName('div')[0];
container.innerHTML = '';
for (var i = 0; i < max; i++)
container.innerHTML += '<fieldset><legend>Entry ' + (i + 1) + ' / ' + max + '</legend><input type="text" name="name' + i + '" /><br /><input type="text" name="topic' + i + '" /></fieldset>';
goto(form, 0);
}
HTML:
<form action="submit.php" method="post" onsubmit="store(this); return false">
<p>
<input type="button" name="prev" onclick="goto(this.form, -1)" value="Previous" />
<input type="button" name="next" onclick="goto(this.form, +1)" value="Next" />
</p>
<div>
<noscript>Please enable JavaScript to see this form correctly.</noscript>
</div>
<p>
<input type="submit" name="submit" value="Store in database" />
</p>
</form>
Users who have JS disabled will see what's in the <noscript> tag, otherwise it's replaced with the fieldsets. Also it's good to make an alternative submit page (submit.php) for users who have JS disabled. Below is store.php, the AJAX submit script.
PHP (store.php):
<?php
if (empty($_POST['n']) || $_POST['n'] < 1) die('Invalid request!');
$fields = array('name', 'topic');
$errors = '';
for ($i = 0; $i < $_POST['n']; $i++) {
foreach ($fields as $field) {
if (empty($_POST[$field . $i]))
$errors .= '- ' . $field . ' ' . ($i + 1) . "\n";
}
}
if ($errors != '')
die("Please fill in the following fields:\n" . $errors);
$db = mysql_connect('localhost', 'root', '');
mysql_select_db('mydb', $db);
for ($i = 0; $i < $_POST['n']; $i++) {
$name = mysql_real_escape_string($_POST['name' . $i]);
$topic = mysql_real_escape_string($_POST['topic' . $i]);
mysql_query(' INSERT INTO entries (id, name, topic) VALUES (' . $i . ', "' . $name . '", "' . $topic . '")
ON DUPLICATE KEY UPDATE name = "' . $name . '", topic = "' . $topic . '"
') or die('Database error!');
}
mysql_close($db);
?>
The output text of this script (if there is an error) is displayed in the JavaScript alert.
I hope it's working for you now.
This would be help ful for you

hi guys I am pretty newbish in javascript and php for that matter. I am making a page where user will choose either to create a radio or input fields for others to solve.
Everything works fine except, when I save the form, fields are not in the order I added them because I first loop over the 'input' fields and then over the 'radio' fields. I know this is probably not the way to do it, feel free to give me an alternative.
Any help would be appreciated, thanks in advance.

Something like this might work.
Maintain the same count variable in the JavaScript to keep track of which input is created.
Instead of using name="fields[]", use name="field_' + count + '" so you can iterate with a loop in the controller.
VIEW
<script type="text/javascript">
var count = 0;
var a=0;
$(function(){
$('span#add_input').click(function(){
count += 1;
$('#pit').append('<p><strong>Pitanje #' + count + '</strong>'+ '<input name="field_' + count + '" type="text" /></p>' );
a=count;
document.write(a);
});
$('span#add_radio').click(function(){
count += 1;
$('#pit').append('<p><strong>DA/NE #' + count + '</strong>'+ '<input name="radio_' + count + '" type="text" /></p>' );
});
});
</script>

Use a regular expression to extract the necessary values.
$inputs = array();
$id=$this->input->post('id');
foreach($_POST as $key => $value) {
$matches = array();
if (preg_match('/(field|radio)_([\d]+)', $key, $matches)) {
$tip = $matches[1];
$count = $matches[2];
$inputs[$count] = array($id, $value, $tip);
}
}
Loop through the new $inputs array to call your add_questions method.
ksort($inputs);
foreach($inputs as $array) {
$id = $array[0];
$value = $array[1];
$tip = $array[2];
$this->page_model->add_questions($id,$value,$tip);
}
Here I am uploading this link http://harvey.binghamton.edu/~rnaik1/myForm.html where you can see how my scroll up n down button is working in javascript but now I am working with Ajax request to a php script on the server to retrieve all of the data from the database table.
Here is the link for the work i have done:http://harvey.binghamton.edu/~rnaik1/myScrollform.html

I try to make web app for creating radio button questions (like survey). The problem is defining the array of radio button options in order to call it on php page and display it in the desirable order.
In my example below, I only got one radio button of each question, and I want to display all radio buttons input on the index.html page.
This should work like this: User opens index.html, there he add the first question (button Add Question) and the proposal of answers (for example 3, which he will get by pressing the Add option button and inserting text of it). The same he should do and for the question number 2, etc...
After that, by clicking PROCEED, it should lead him to the process.php page where the survey will display radio buttons questions. But there is a mistake, please see it on the link or in the code below:
LINK FOR TESTING
index.html
<script src="script.js"></script>
<form action="http://www.balkanex.info/atest/radio/process.php" method="post">
Here is the page with which you can add your new radio button questions for survey.
<input type="button" value="ADD NEW QUESTION" onclick="addradio();">
<div id="mydiv"></div>
<br/>
<input type="submit" name="submit" value="PROCEED"><br/>
</form>
script.js
n=1;
var m = 1;
var moreradio = '<br/><input type="button" onclick="addmoreradio()" value="Add option">';
function addradio() {
m = 1;
var textarea = document.createElement("textarea");
textarea.name = "question[" + n + "]";
textarea.rows = 1;
textarea.cols = 60;
var div = document.createElement("div");
div.innerHTML = n + '. Question: ' + '<br />' + 'Que: ' + textarea.outerHTML + moreradio + '<br/><div id="opid' + n + '"' + '></div><br /><br/>';

function addmoreradio() {
var radio = '<input type="text" name="tag' + r + m + '"><br/>';
document.getElementById("opid"+r).innerHTML += radio;

$question = $_POST['question'];

You can did a mistake on form side while naming elements. Also you did mistake on backend while iterating. You can use following;
JS:
<script>
var m = 0;
function addradio() {
var textarea = document.createElement("textarea");
textarea.name = "question[]";
textarea.rows = 1;
textarea.cols = 60;
var div = document.createElement("div");
div.innerHTML = m + '. Question: ' + '<br />' + 'Que: ' + textarea.outerHTML + '<br/><input type="button" onclick="addmoreradio(' + m + ')" value="Add option">' + '<br/><div id="opid' + m + '"' + '></div><br /><br/>';
document.getElementById("mydiv").appendChild(div);
m++;
}
function addmoreradio(question_id) {
var radio = '<input type="text" name="tag' + question_id + '[]"><br/>';
document.getElementById("opid" + question_id).innerHTML += radio;
}
</script>
HTML:
<script src="script.js"></script>
<form action="http://www.balkanex.info/atest/radio/process.php" method="post">
Here is the page with which you can add your new radio button questions for survey.
<input type="button" value="ADD NEW QUESTION" onclick="addradio();">
<div id="mydiv"></div>
<br/>
<input type="submit" name="submit" value="PROCEED"><br/>
</form>
PHP:
<?php
$question = $_POST['question'];
$content = '';
foreach ($question as $k => $v) {
$area = '';
$options = $_POST["tag" . $k];
foreach ($options as $key => $val) {
$area .= '<input type="radio" name="tag[]" value="'. $key .'">' . $val . '<br/>';
}
$content .= $k + 1 . ') ' . $question[$k].'<br/>'.$area.'<br/><br/>';
}
echo $content;
?>
This is all my code I hope you can see where I'm going wrong.
var $randomnumber1;
var $randomnumber2;
var $answer;
var $counter = 1;
var $data;
function start_game() {
document.getElementById('counternumber').innerHTML = $counter;
document.getElementById('txtbox').value = "";
$randomnumber1 = Math.floor(Math.random()*11);
document.getElementById('num1').innerHTML = $randomnumber1;
$answer = $randomnumber1 + $randomnumber2;
$counter++;
setFocus();
}
function check_answer() {
var $txt = document.getElementById('txtbox');
var $value = $txt.value;
if ($value == $answer) {
alert('You are correct');
}
else {
alert('You are incorrect, the answer was ' + $answer);
}
document.getElementById('txtbox').value = "";
document.getElementById('num1').innerHTML = "";
document.getElementById('num2').innerHTML = "";
$randomnumber1 = Math.floor(Math.random()*11);
$randomnumber2 = Math.floor(Math.random()*11);
document.getElementById('num1').innerHTML = $randomnumber1;
document.getElementById('num2').innerHTML = $randomnumber2;
$answer = $randomnumber1 + $randomnumber2;
document.getElementById('counternumber').innerHTML = $counter;
$counter++;
if ($counter > 4) {
alert ('End of game......Thanks for playing');
$counter = 1;
document.getElementById('num1').innerHTML = "";
document.getElementById('num2').innerHTML = "";
}
function addAnswers() {
var data = $randomnumber1 + " + " + $randomnumber2 + " = " + ($randomnumber1+$randomnumber2)
var newListItem = document.createElement('li');
var newText = document.createTextNode(data);
newListItem.appendChild(newText);
document.getElementById("ans").appendChild(newListItem);
}
<div class="container" id="wrapper">
<h3>Games Played = <b id='counternumber'></b> / 3 </h3>
<div id="total">Total: <p id="sumtotal"></p></div>
<div class="left"><h3 id="num1"></h3></div>
<div class="plus"><img src="images/plus.png"></div>
<div class="right"><h3 id="num2"></h3></div>
<button onclick="start_game(); myCountDown()">Start Game</button>
<form id="form">
<input type="text" id="txtbox" />
<input type="button" value="Answer" onclick="check_answer(); setFocus(); ShowResults(); sumResults()" />
</form>
</div>
home page
</div> <!-- /content -->
<div id="aside">
</div>
You could use this:
function addAnswers()
{
var data = $randomnumber1 + " + " + $randomnumber2 + " = " + ($randomnumber1+$randomnumber2)
var newListItem = document.createElement('li');
var newText = document.createTextNode(data);
newListItem.appendChild(newText);
document.getElementById("ans").appendChild(newListItem);
}
Your question is unclear, but this should be something along the lines of what you're looking for. What you have to do is add a <ul> with the id of ans and this function will append li components to it (your answers) every time you run it. The answer itself will be stored into data.
Try it - if you want help customizing it, please update your answer.
