auto generate text field value when dropdown is select

hello i'm using Yii framework and oracle database. i need some help to solve this problem. i've a form for sending an email. my form looks like this
email desc: _______|v| (dropdown value form database)
email subject : _________ (this field will automatically filled with data of selected email subject)
email body : _______ (this field will automatically filled with data of selected email subject)
my table:
email_desc| subject| body_email
payment1 | payment for house rent | address: **** city: jakarta
ex: i choose email_desc as payment1, email subject will automatically filled as "payment for rent" and email body will automatically filled as address: **** city: jakarta
here is my form
<div class="control-group">
<?php echo $form->labelEx($model,'EMAIL_DESC', array('class'=>'control-label')); ?>
<?php echo $form->dropDownlist($model,'EMAIL_DESC',
(CHtml::listData (TrnProjImplement::model()->getList(),'EMAIL_DESC','EMAIL_DESC')),
array(
'empty'=>'--Pilih salah satu--',
'value'=>$model->EMAIL_DESC,
'id'=>"dropDown",
'ajax'=>array(
'type'=>'GET',
'url'=>CController::createUrl('email/field'),
'update'=>'#subject',
'data'=>array('EMAIL_DESC'=>'js: this.value'),
),
));
?>
<span class="help-inline text-error"><?php echo $form->error($model,'EMAIL_DESC'); ?></span>
</div>
<div class="control-group">
<?php echo $form->labelEx($model,'SUBJECT', array('class'=>'control-label')); ?>
<?php echo $form->textField($model,'SUBJECT',array('size'=>60,'maxlength'=>100, 'style'=>'width:600px', 'id'=>"subject"));?>
<?php //echo CHtml::activeTextField($model, 'SUBJECT',
// array(
// 'ajax'=>array(
// 'type'=>'POST',
// 'url'=>Yii::app()->createUrl('email/create'),
// 'id'=>'subject',
// ),
// ));
?>
<span class="help-inline text-error"><?php echo $form->error($model,'SUBJECT'); ?></span>
</div>
<!--<div class="control-group" id="body-email">-->
<div class="control-group">
<?php echo $form->labelEx($model,'BODY_EMAIL', array('class'=>'control-label')); ?>
<?php echo $form->textArea($model,'BODY_EMAIL',array('size'=>1000,'maxlength'=>1000,'style'=>'height:200px; width:600px;', 'id'=>"body-email")); ?>
<span class="help-inline text-error"><?php echo $form->error($model,'BODY_EMAIL'); ?></span>
</div>
javascript
<script>
function insertField(){
var desc = document.getElementById("dropDown").value;
var subj = document.getElementById("subject").value;
var body = document.getElementById("body-email").value;
$.ajax({
type : "POST",
url : "<?php echo Yii::app()->createUrl("emaildetail/field"); ?>",
data : {
"desc" : desc,
"subj" : subj,
"body" : body,
},
success: function (){
alert('asd');
},
});
</script>
my controller
public function actionField(){
if(isset($_POST['desc'])){
$connection=Yii::app()->db;
$desc = Yii::app()->request->getPost('desc');
$subj = Yii::app()->request->getPost('subj');
$body = Yii::app()->request->getPost('body');
$sql = 'SELECT SUBJECT FROM EMAIL_DETAIL WHERE EMAIL_DESC = $desc';
$sql2 = 'SELECT BODY_EMAIL FROM EMAIL_DETAIL WHERE EMAIL_DESC = $desc';
$model2 = EMAIL_DETAIL::model()->findByAttributes(array('EMAIL_BODY'=>$desc));
if(isset($desc)){
$subj = $model->SUBJECT;
$body = $model->EMAIL_BODY;
}
}
}
i could get the value of email_desc but i still cant automatically fill other field

You can change your code as following solution.
Please change your form as below code :
<div class="control-group">
<?php echo $form->labelEx($model,'EMAIL_DESC', array('class'=>'control-label')); ?>
<?php echo $form->dropDownlist($model,'EMAIL_DESC',
(CHtml::listData (TrnProjImplement::model()->getList(),'EMAIL_DESC','EMAIL_DESC')),
array(
'empty'=>'--Pilih salah satu--',
'value'=>$model->EMAIL_DESC,
'id'=>"dropDown",
'ajax'=>array(
'type'=>'POST',
'url'=>CController::createUrl('email/field'),
'data'=>array('EMAIL_DESC'=>'js: this.value'),
'success'=> 'function(response) {if (response.status == "success") {
$("#SUBJECT").val(response.subj);
$("#BODY_EMAIL").val(response.body);
} else {
$("#SUBJECT").val("");
$("#BODY_EMAIL").val("");
}
}',
'error'=> 'function(){alert("AJAX call error..!!!!!!!!!!");}',
),
));
?>
<span class="help-inline text-error">
<?php echo $form->error($model,'EMAIL_DESC'); ?>
</span>
</div>
<div class="control-group">
<?php echo $form->labelEx($model,'SUBJECT', array('class'=>'control-label')); ?>
<?php echo $form->textField($model,'SUBJECT',array('size'=>60,'maxlength'=>100, 'style'=>'width:600px', 'id'=>"subject"));?>
<span class="help-inline text-error"><?php echo $form->error($model,'SUBJECT'); ?></span>
</div>
<div class="control-group">
<?php echo $form->labelEx($model,'BODY_EMAIL', array('class'=>'control-label')); ?>
<?php echo $form->textArea($model,'BODY_EMAIL',array('size'=>1000,'maxlength'=>1000,'style'=>'height:200px; width:600px;', 'id'=>"body-email")); ?>
<span class="help-inline text-error"><?php echo $form->error($model,'BODY_EMAIL'); ?></span>
</div>
Please change your Controller code :
<?php
public function actionField() {
if (Yii::app()->request->isAjaxRequest){
$desc = Yii::app()->request->getPost('EMAIL_DESC');
$model = EMAIL_DETAIL::model()->findByAttributes(array('EMAIL_BODY' => $desc));
if (!empty($model)) {
$data['status'] = 'success';
$data['subj'] = $model->SUBJECT;
$data['body'] = $model->EMAIL_BODY;
} else {
$data['status'] = 'error';
$data['subj'] = '';
$data['body'] = '';
}
echo json_encode($data);
Yii::app()->end();
} else
throw new CHttpException(400, '404_error_message');
}
?>
I hope this will helps you. Thanks!

JavaScript error and database update

I have a problem with my database and doing the update of it. I have a database table stock with 5 columns (stock_id, p_id, brand_id, cat_id, availability). I want to do an update from the frontend. So when the popup show up and I fill in the form, UPDATE doesn't work. I have 3 files. First one stock.php that read database and works fine. the seconf one that open if you click edit looks like this:

This is my code for update-stock.php that supposed to be updating the database:
<?php
session_start();
include ( 'config.php' );
require_once( 'class.db.php' );
$database = DB::getInstance();
if($_POST) {
$stock_id = $_POST['stock_id'];
$brand = $_POST['brand'];
$category = $_POST['category'];
$product = $_POST['product'];
$availability = $_POST['availability'];
$update = array(
'p_id' => $product,
'brand_id' => $brand,
'cat_id' => $cat,
'availability' => $availability
);
$where_clause = array(
'stock_id' => $stock_id
);
$updated = $database->update( 'stock', $update, $where_clause, 1 );
}
?>
I have a 2 problems.
Update doesn't work at all. I am just getting the message Please Enter Valid Data
My form doesn't show up the correct value of the PRODUCT NAME. Example: In the database and my main table that read information from database product name is 2.1.1 but when I click on edit and open my pop-up form that show up 2.1.3 for example.
Thank you so much in advance for your help.
This one works PERFECT fetch_brand.php:

$where_clause = array(

$updated = $database->update( 'product', $update, $where_clause, 1 );

This one works excellent! So I am pretty sure that I made a mistake in my code for the stock.

PHP forms through loop doesn't send specific session against checked radio button

I am working on an e-testing system in which when a candidate login the test for which he/she was register will be shown to him/her.
I am getting the specific test through session to show the questions containing in that test. This was successfully done with the help of some "if" checks and two while loops(1 for questions and 2nd for answers against that question) having the form of radio buttons for selecting an answer.
Now each time when loop execute it create a form for single question and its answer, that way for multiple questions it results in multiple.
I am getting the checked radio buttons through ajax and posting it to another php file but I need a question id of checked answer as well to be passed to the 2nd php file
I used session but it only get the id of 1st checked and not for the others.
The 2nd php file name is answers.php for the time being i just want to post and get all values and session in answers.php file.
the main problem is with $_SESSION ['qid'] = $id; session
Note: i have used unset and destroy session to free the session and tried to re start it but i am field to do so..
<?php
include ("connection.php");
// $mysql_row = '';
$query_run = null;
$test = $_SESSION ['id'];
var_dump ( $_SESSION ['id'] );
$query1 = "SELECT * FROM question where testid = '" . $_SESSION ['id'] . "'";
if ($query_run = mysql_query ( $query1 )) {
if (mysql_num_rows ( $query_run ) == null) {
print "No result";
} else {
// echo'<form action="ss.php" method="post">';
while ( $mysql_row = mysql_fetch_assoc ( $query_run ) ) {
$id = $mysql_row ['qid'];

How to separate data and register it in a database

I'm trying to separate the data that I get here and trying to register it in the database.
I get the data with a form that looks like this.
var max_input_fields=10;
var delimiter='|';
function http( data, callback ){
var xhr=new XMLHttpRequest();
xhr.onreadystatechange=function(){
if( xhr.readyState==4 && xhr.status==200 ) callback.call( this, xhr.response );
};
xhr.open( 'POST', document.location.href, true );
xhr.send( data );
}
function cbhttp(r){
document.querySelectorAll('output')[0].innerHTML=r
}
function bindEvents(){
var oBttnAdd=document.getElementById('bttnadd');
var oBttnSub=document.getElementById('bttnsub');
var oForm=document.getElementById('dynelems');
var oParent=document.getElementById('loopdiv');
oBttnSub.onclick=function(e){
/* scan the form and get values from all elements ( including dynamcially added ) and submit the form via xhr */
var col=oForm.querySelectorAll('input[type="text"],textarea,select');
var data=new FormData();
data.append('delimiter',delimiter);
for( var n in col ) if( col[n] && col[n].nodeType==1 ) {
data.append( col[n].name, col[n].value.replace( delimiter, '' ) + delimiter );
}
http.call( this, data, cbhttp );
};
oBttnAdd.onclick=function(e){
/* Add new rows based upon selected option from dropdown menu */
var col=oParent.querySelectorAll('section[data-id]');
var length=col.length;
if( length < max_input_fields ){
var newid=parseInt( col[ length-1 ].dataset.id ) + 1;
var clone=oParent.childNodes[1].cloneNode( true );
clone.dataset.id=newid;
/* Set new name for the textarea */
clone.childNodes[3].childNodes[1].name='videolink'+newid;
oParent.appendChild( clone );
}
}
}
document.addEventListener('DOMContentLoaded', bindEvents,false);
<form action="adddilemman.php" id="dynelems" method="post" enctype="multipart/form-data">
<br>
<div id='loopdiv'>
<?php
/* Data-id is used by js to determine next suitable id */
echo "
<section data-id=1>
<h2>Dilemma</h2>
<div>Video länk:<br><textarea rows='1' cols='40' name='videolink1'></textarea></div>";
for( $i=1; $i <= 4; $i++ ){
/* Add four text fields and four select menus */
echo "
<div>
Answer: <input type='text' name='answer{$i}[]'/>
<select name='options{$i}[]'>";
/* Add options to each select menu */
for( $j=1; $j <= 10; $j++ ){
echo "<option value={$j}>{$j}";
}
/* Close each nested div & select menu */
echo "
</select>
</div>";
}
/* Close initial section */
echo "
</section>";
?>
</div>
<div class='input_fields_wrap'>
<div></div>
</div>
<input id='bttnadd' type='button' name='add_field_button' value='Lägg till fler svar'/>
<input id='bttnsub' type='submit' name='sub' value='Submit'/>
</form>
<output></output>
I'm using "adddilemman.php" to show the data just to see if its working and its working. But I have now idea how to register this data in the database. PS I want to register it in two different tables (textarea in a table and answers in another table)
<?php
if( $_SERVER['REQUEST_METHOD']=='POST' ){
ob_clean();
/* This is here only to simplify development and display here */
$delimiter=isset( $_POST['delimiter'] ) ? $_POST['delimiter'] : '|';
/* process form submission: for testing purposes just echo out data sent */
foreach( $_POST as $field => $value ) {
if( $field!='delimiter' ){
if( is_array( $value ) ) echo 'Array values: '.$field.'='.rtrim( str_replace( $delimiter, ',', implode( ' ', $value ) ), ',' ).'<br />';
else echo 'String value: '.$field.'='.trim( str_replace( $delimiter, '', $value ) ).'<br />';
}
}
exit();
}
?>
Any recommendations how I can separate this data and register it in the database?

You would want to setup the form like so:
<textarea rows='1' cols='40' name='videolink1'><?php echo isset($_POST['videolink1'])?$_POST['videolink1']:""; ?></textarea>
<?php
for( $i=1; $i < 5; $i++ ){
/* Add four text fields and four select menus */
?>
<div>
<label>Answer:</label>
<input type='text' name='answer[<?php echo $i; ?>]' value="<?php echo isset($answer[$i])?$answer[$i]:''; ?>" />
<select name='options[<?php echo $i; ?>]'>
<?php
for( $j=1; $j <= 10; $j++ ){
if($options[$i] == $j){
echo "\t\t\t\t\t<option selected='selected' value={$j}>{$j}</option>\r\n";
} else {
echo "\t\t\t\t\t<option value={$j}>{$j}</option>\r\n";
}
}
?>
</select>
</div>
<?php
}
?>
I would prepare the post data like so:
<?php
$vidlink = "";
$answers = array();
$options = array();
if(isset($_POST['sub'])){
$vidlink = htmlentities($_POST['videolink1']);
for($i=1;$i<=count($_POST['answer']);$i++){
$answer[$i] = $_POST['answer'][$i];
$options[$i] = $_POST['options'][$i];
}
}
?>
This will place the content of the answers and options in their own arrays but with the same indexes. You can loop and place them in the DB any way you like. Here is an example:
$con = mysqli_connect("localhost", "root", "", "wildfire");
if($con === false){
die("ERROR: Could not connect. " . mysqli_connect_error());
}
for($i=1;$i<=$count($answer);$i++){
if ($stmt = mysqli_prepare($con, "INSERT INTO answer_det ('aid', 'answer', 'points') VALUES (?, ?, ? )")) {
mysqli_stmt_bind_param($stmt, "isi", $i, $answer[$i], $options[$i]);
mysqli_stmt_execute($stmt);
}
}
Here is all the code I used for testing on phpfiddle.org:
<?php
$vidlink = "";
$answers = array();
$options = array();
if(isset($_POST['sub'])){
$vidlink = htmlentities($_POST['videolink1']);
for($i=1;$i<=count($_POST['answer']);$i++){
$answer[$i] = $_POST['answer'][$i];
$options[$i] = $_POST['options'][$i];
}
}
?>
<html>
<body>
<form action="<?php echo $_SERVER['PHP_SELF']; ?>" id="dynelems" method="post" enctype="multipart/form-data">
<div id='loopdiv'>
<section data-id=1>

How to retain dropdown value after the page is reloaded?

How to retain my dropdown value after page reload? The form reloads after I submit and validates an error. Now I just want to retain the dropdown value after the form gets an error.

You can use localStorage to store selected value:
$('#mod_simpleemailform_field1_1').on('change', function() {
// Save value in localstorage
localStorage.setItem("mod_simpleemailform_field1_1", $(this).val());
});
On page refresh, get the value from localStorage and set to the select:
$(document).ready(function() {
if ($('#mod_simpleemailform_field1_1').length) {
$('#mod_simpleemailform_field1_1').val(localStorage.getItem("mod_simpleemailform_field1_1"));
}
});
localStorage is not supported in all browsers. You can use shims for that or fallback to cookie.

It is possible through PHP and you are doing it wrong select elements do not have value attributes:
So first of all remove value attribute:
<select name="mod_simpleemailform_field1_1" id="mod_simpleemailform_field1_1"
class="mod_sef_input_select select" value="<?php echo $day; ?>">
And use selected attribute on option tag.
<select name="mod_simpleemailform_field1_1" id="mod_simpleemailform_field1_1"
class="mod_sef_input_select select">
<option value="">Day</option>
<?php
for($i = 1; $i <= 10; $i++) {
if($day == $i) {
echo '<option selected="selected">' . $i . '</option>';
} else {
echo '<option>' . $i . '</option>';
}
}
</select>

you can use local storage
// set value of dropdown into local storage
localStorage.setItem("StorageName", "DropDownValue");
// retrieve value from local storage
var ddlValue = localStorage.getItem("StorageName");
