I have some dropdown select as below
<div class="dep" style="display: inline;">
<select name="dep" id="dep" class="drp" style="width:19%;">
<option value="">Choose departament</option>
<?php
if($rowCount > 0){
while($row = $query->fetch_assoc()){
$selected = "";
if(isset($_POST['dep'])){
if ($_POST['dep'] == $row['D_id']) {
$selected = "selected='selected'";
}
}
echo '<option value="'.$row["D_id"].'" '.$selected.' >'.$row['Emri'].'</option>';
}
}else{
echo '<option value="">No Departaments</option>';
}
?>
</select>
</div>
The below dropdown filled when i select department using ajax
<div class="dega" style="display: inline;">
<select name="dega" id="dega" class="drp" style="width:19%;">
<option value="">Choose Sector </option>
</select>
</div>
to be filled need the follows :
ajax:
<script type="text/javascript">
$(document).ready(function(){
$('#dep').on('change',function(){
var dep_id = $(this).val();
if(dep_id){
$.ajax({
type:'POST',
url:'ajaxData.php',
data:'D_id='+dep_id,
success:function(html){
$('#dega').html(html);
}
});
}else{
$('#dega').html('<option value="">choose departament</option>');
}
});
});
And the ajaxData.php file where the ajax code take the values
include('dbConfig.php');
if(isset($_POST["D_id"]) && !empty($_POST["D_id"])){
$query = $db->query("SELECT * FROM deget WHERE D_id = ".$_POST['D_id']."");
$rowCount = $query->num_rows;
if($rowCount > 0){
echo '<option value="">Choose sector</option>';
while($row = $query->fetch_assoc()){
$sel = "";
if (isset($_POST['dega'])) {
if ($_POST['dega'] == $row['Dg_id']) {
$sel = "selected='selected'";
}
}
echo '<option value="'.$row['Dg_id'].'" '.$sel.'>'.$row['Emri'].'</option>';
}
}else{
echo '<option value="">No sectors revalent to department</option>';
}
}
Everything works fine except something.When i post the button all my dropdown are selected because i use selected='selected' EXCEPT the second dropdown choose sector and that because i have used ajax.I have tried on php file that took with ajax to make the option selected but it does not works.Any idea?
i find my problem and the solution is :
<div class="dega" style="display: inline;">
<select name="dega" id="dega" class="drp" style="width:19%;">
<?php if(isset($_POST['kot'])){
//Include database configuration file
include('dbConfig.php');
//Merr te dhenat e degeve perkatese te departamentit te selektuar
$query = $db->query("SELECT * FROM deget WHERE D_id = ".$_POST['dep']."");
//Rreshtat e querit
$rowCount = $query->num_rows;
//Mbush dropdown e degeve
if($rowCount > 0){
echo '<option value="">Zgjidh Degen</option>';
while($row = $query->fetch_assoc()){
$sel = "";
if($_POST['dega'] == $row['Dg_id']){
$sel = "selected='selected'";
}
echo '<option value="'.$row['Dg_id'].'" '.$sel.'>'.$row['Emri'].'</option>';
}
}else{
echo '<option value="">Nuk ka dege perkatese</option>';
}
}else{?>
<option value="">Selekto Degen </option>
<?php }?>
</select>
</div>

I am newbie to JQuery Ajax. May i know how to create a PHP to read the subcategory list depends on the selected maincategory? So far i had create a jQuery AJAX in my asset_add.php
<script src="jquery.min.js"></script>
<script type="text/javascript">
$(document).ready(function()
{
$('#main_category').on('change',function(){
var categoryNAME = $(this).val();
if(categoryNAME){
$.ajax({
type:'POST',
url:'ajaxData.php',
data:'ac_maincategory='+categoryNAME,
success:function(html){
$('#sub_category').html(html);
}
});
}else{
$('#sub_category').html('<option value="">Select main category first</option>');
}
});
});
</script>
and for HTML,
<tr>
<td valign=top><strong>MAIN CATEGORY</td>
<td><select name="main_category" id="main_category" onchange="this.form.submit()" required>
<?php
$sql = "SELECT * FROM asset_category GROUP BY ac_maincategory" ;
$result = mysqli_query($conn, $sql);
$count=mysqli_num_rows($result);
?>
<option value=""></option>
<?php
if($count > 0)
{
while ($rs = mysqli_fetch_array($result))
{
$ac_maincategory = $rs["ac_maincategory"];
$ac_id = $rs["ac_id"];
?>
<option value="<?=$ac_id?>"><?=$ac_maincategory?></option>
<?php
}
}
?>
</select>
</td>
</tr>
<tr>
<td valign=top><strong>SUB CATEGORY</td>
<td><select id= "sub_category" name="sub_category" autocomplete="off"/ required>
<option value=""></option>
</select>
</tr>
while in my ajaxData.php
<?php
//Include database configuration file
require("config.php");
$conn = dbconnect();
if(isset($_POST["ac_maincategory"]) && !empty($_POST["ac_maincategory"]))
{
$sql = "SELECT * FROM asset_category WHERE ac_maincategory = ".$_POST['ac_maincategory']."" ;
$result = mysqli_query($conn, $sql);
$count=mysqli_num_rows($result);
if($count > 0)
{
echo '<option value="">Select Subcategory</option>';
while ($rs = mysqli_fetch_array($result))
{
$ac_subcategory = $rs["ac_subcategory"];
$ac_id = $rs["ac_id"];
echo '<option value="'.$rs['ac_subcategory'].'">'.$rs['ac_subcategory'].'</option>';
}
}
}
?>
However, when i choose a maincategory in asset_add.php, nothing shown in subcategory. Can anyone tell me which part i do wrong? Thanks for help
Seems you are replacing whole div with $('#sub_category').html(html); so there is only options printed on the view
You can solve it by replacing the line
$('#sub_category').html(html);
to
$('#sub_category').append(html);
Or Just replace this code in ajaxData.php , S
//Include database configuration file
require("config.php");
$conn = dbconnect();
if(empty($_POST["ac_maincategory"])){
die("category is empty");
}
$sql = "SELECT * FROM asset_category WHERE ac_maincategory = " . $_POST['ac_maincategory'];
$result = mysqli_query($conn, $sql);
$count = mysqli_num_rows($result);
if($count > 0)
{
echo '<select id= "sub_category" name="sub_category" autocomplete="off"/ required>';
echo '<option value="">Select Subcategory</option>';
while ($rs = mysqli_fetch_array($result))
{
$ac_subcategory = $rs["ac_subcategory"];
$ac_id = $rs["ac_id"];
echo '<option value="'.$rs['ac_subcategory'].'">'.$rs['ac_subcategory'].'</option>';
}
echo "</select>";
}
this is simple question and should be fixed ASAP. but idk why still not solved yet.
so, please try this
html
remove onchange attribute (remove native js event trigger style with jquery style)
optional:
fix several unclosed tag html
remove unrecomended PHP writing style
into this
<tr>
<td valign="top"><strong>MAIN CATEGORY</strong></td>
<td>
<select name="main_category" id="main_category" required>
<option value=""></option>
<?php
$sql = "SELECT * FROM asset_category GROUP BY ac_maincategory" ;
$result = mysqli_query($conn, $sql);
$count=mysqli_num_rows($result);
if($count > 0)
{
while ($rs = mysqli_fetch_array($result))
{
echo '<option value="'. $rs["ac_id"] .'">'.$rs["ac_maincategory"].'</option>';
}
}
?>
</select>
</td>
</tr>
<tr>
<td valign="top"><strong>SUB CATEGORY</strong></td>
<td>
<select id= "sub_category" name="sub_category" autocomplete="off" required>
<option value="">Select main category first</option>
</select>
</td>
</tr>
jquery
change on('change') with change() // possible dont know when to use on or not
change wrong comparasion on categoryNAME
optional:
change serialize data style using data {} //better for newbie to study
into this
<script>
$(function(){
$('#main-category').change(, function(){
var categoryNAME = $(this).val();
if(categoryNAME != ''){
$.ajax({
type:'POST',
url:'ajaxData.php',
data:{ac_maincategory: categoryNAME},
success:function(html){
$('#sub_category').html(html);
}
});
}else{
$('#sub_category').html('<option value="">Select main category first</option>');
}
})
});
</script>
PHP
reposition default sub-category value out of $count comparasion
into this
<?php
//Include database configuration file
require("config.php");
$conn = dbconnect();

I want to add part search into a website powered by WordPress. I have currently achieved the function, but I have trouble of integrating it into WordPress. I tried several ways but the dynamic dependent select box still not working.
I followed this tutorial: Dynamic Dependent Select Box using jQuery, Ajax and PHP
Below are my code which works well outside WordPress.
index.php
<head>
<script src="http://code.jquery.com/jquery-3.1.1.min.js"></script>

<option value="">Select Manufacturer</option>
<?php
if($rowCount > 0){
while($row = $query->fetch_assoc()){

Now the problem is, when select the first box, the second one becomes empty, nothing is returned from the database:
Capture - After select the first box
Really appreicate Christos Lytras to help me solve the previous problem.
I have a new problem with action="ps-result.php" in the line <form class="select-boxes" action="ps-result.php" method="POST">.
ps-result.php
<?php
if (isset($_POST['search'])) {
$clauses = array();
if (isset($_POST['manufacturer_text']) && !empty($_POST['manufacturer_text'])) {
$clauses[] = "`manufacturer` = '{$_POST['manufacturer_text']}'";
}
if (isset($_POST['type_text']) && !empty($_POST['type_text'])) {
$clauses[] = "`type` = '{$_POST['type_text']}'";
}
if (isset($_POST['year_text']) && !empty($_POST['year_text'])) {
$clauses[] = "`year` = '{$_POST['year_text']}'";
}
if (isset($_POST['model_text']) && !empty($_POST['model_text'])) {
$clauses[] = "`model` = '{$_POST['model_text']}'";
}
$where = !empty( $clauses ) ? ' where '.implode(' and ',$clauses ) : '';
$sql = "SELECT * FROM `wp_products` ". $where;
$result = filterTable($sql);
}
else {
$sql = "SELECT * FROM `wp_products` WHERE `manufacturer`=''";
$result = filterTable($sql);
}
function filterTable($sql) {
$con = mysqli_connect("localhost", "root", "root", "i2235990_wp2");
if (!$con) {

$filter_Result = mysqli_query($con, $sql);
return $filter_Result;
}
?>
<?php get_header(); ?>
<div class="container">

<?php get_footer(); ?>
Now when I click Search, it returns

The proper way to do this, is to create a wordpress shortcode and then use that shortcode wherever you want, page or post, but if you want to create something more specific, then you should create a small wordpress plugin. I won't get into this, but it’s really not a big deal to create a simple wordpress plugin having such functionality. I’ll go through the steps on how you can have this working in wordpress with the files and the code you already have.
I assume you already have the tables of your example created. My tables are like this:
wp_citytours_dynsel_cities
wp_citytours_dynsel_states
wp_citytours_dynsel_countries
I have imported some data and I have all those tables filled with proper data. I can provide some sql files if you like, but I assume you already have your tables filled with the proper data for each table.
My test theme root directory is:
/wp-content/themes/citytours/
I have created the directory under my theme root directory and I have included all the code files there, so we have 3 files:
/wp-content/themes/citytours/dynsel/index-partial.php
<?php
//Include database configuration file
include('dbConfig.php');
//Get all country data
$query = $db->query("SELECT * FROM wp_citytours_dynsel_countries WHERE status = 1 ORDER BY country_name ASC");
//Count total number of rows
$rowCount = $query->num_rows;
?>
<select name="country" id="country">
<option value="">Select Country</option>
<?php
if($rowCount > 0){
while($row = $query->fetch_assoc()){
echo '<option value="'.$row['country_id'].'">'.$row['country_name'].'</option>';
}
}else{
echo '<option value="">Country not available</option>';
}
?>
</select>
<select name="state" id="state">
<option value="">Select country first</option>
</select>
<select name="city" id="city">
<option value="">Select state first</option>
</select>
<script type="text/javascript">
jQuery(function($) {
$('#country').on('change',function(){
var countryID = $(this).val();
if(countryID){
$.ajax({
type:'POST',
url:'<?php echo home_url('wp-content/themes/citytours/dynsel/ajaxData.php') ?>',
data:'country_id='+countryID,
success:function(html){
$('#state').html(html);
$('#city').html('<option value="">Select state first</option>');
}
});
}else{
$('#state').html('<option value="">Select country first</option>');
$('#city').html('<option value="">Select state first</option>');
}
});
$('#state').on('change',function(){
var stateID = $(this).val();
if(stateID){
$.ajax({
type:'POST',
url:'<?php echo home_url('wp-content/themes/citytours/dynsel/ajaxData.php') ?>',
data:'state_id='+stateID,

//Display states list
if($rowCount > 0){
echo '<option value="">Select state</option>';
while($row = $query->fetch_assoc()){

As you can see, the index-partial.php now contains only needed code, without <body>, <head> and script files included. Wordpress already includes jQuery to the application for most themes, but you should always check that.
Now, you can add the functionality wherever you want, even at the theme index.php file, but always with caution. I have used theme's single post template file, which is single-post.php. I have included the example code, under the main post body inside a div. I just include the index-partial.php like this:
<div class="<?php echo esc_attr( $content_class ); ?>">
<div class="box_style_1">
...
</div><!-- end box_style_1 -->
<div class="box_style_1">
<?php include(__DIR__.'/dynsel/index-partial.php'); ?>
</div>
</div><!-- End col-md-9-->
I also have used the wordpress home_url function, to have a proper url rooted for the ajaxData.php file like this:
url:'<?php echo home_url('wp-content/themes/citytours/dynsel/ajaxData.php') ?>'
Now, if you have followed all these steps, then you should have your code example working at under each post. You can now included it wherever you want by using that line of code <?php include(__DIR__.'/dynsel/index-partial.php'); ?>.
Please let me know if that worked for you.
I have 2 select options, Make and Model.. I have data in my DB with a bunch of different vehicles and would like the model field to update based on the make selection..
** UPDATED QUESTION WITH EXTERNAL PHP FILE FOR AJAX CALL **
So I made this change, I have dataAJax.php -
if(isset($_POST["make"]) && !empty($_POST["make"])){
$query = $db->query("SELECT DISTINCT Make, Model FROM inv WHERE Make = ".$_POST['Make']."");
$rowCount = $query->num_rows;
if($rowCount > 0){
echo '<option value="">Select model</option>';
while($row = $query->fetch_assoc()){
echo '<option value="'.$row['Model'].'">'.$row['Model'].'</option>';
}
}else{
echo '<option value="">Model not available</option>';
}
}
Index.php -
$query = $conn->query("SELECT DISTINCT Make FROM inv");
$rowCount = $query->num_rows;
?>
<select name="make" id="make">
<option value="">Select Make</option>
<?php
if($rowCount > 0){
while($row = $query->fetch_assoc()){
echo '<option value="'.$row['Make'].'">'.$row['Make'].'</option>';
}
}
?>
</select>
<select name="model" id="model">
<option value="">Select Make first</option>
</select>
And here is my ajax call -
$(document).ready(function(){
$('#make').on('change',function(){
var make = $(this).val();
if(make){
$.ajax({
type:'POST',
url:'dataAjax.php',
data:'make='+make,
success:function(html){
$('#model').html(html);
}
});
}else{
$('#make').html('<option value="">Select Model First</option>');
}
});
});
The problem I have is it doesn't populate the model field it just gets the else statement " Model Not Available"
I figured out my problem it was with my sql query in dataAjax.php -
$make = $_POST['make'];
$query = $conn->query("SELECT * FROM inv WHERE Make = '$make'");
$rowCount = $query->num_rows;
if($rowCount > 0){
echo '<option value="">Select model</option>';
while($row = $query->fetch_assoc()){
echo '<option value="'.$row['Model'].'">'.$row['Model'].'</option>';
}
}else{
echo '<option value="">Model not available</option>';
}
I am using dropdown to select values, and after I click the submit button, my values change. Please help me retain the selected values. Using POST method I have got the solution, but I want to use with GET method. Is it possible?
1.) 1st select stmt:
<form action="" method="GET">
<select name="sort" >
<option value="inc_patientName">Patient Name</option>
<option value="inc_date">Date</option>
<option value="inc_status">Status</option>
<option value="inc_patientAge">Age</option>
</select>
<input type="submit" name="GETREPORT" value="Get Report"/>
if ($_GET)
{echo"hi";}
</form>
2.) 2nd select with while
<?php
//Selecting ward from table ward master
$sql = "SELECT ward_name,ward_id FROM ward_master";
$result = mysql_query($sql);
echo "<select name='ward'>";
while ($row = mysql_fetch_array($result))
{
echo "<option value='" . $row['ward_id'] . "'>" . $row['ward_name'] . "</option>";
}
echo "</select>";
?>
3.) 3rd select with javascript:
<select name="daydropdown" id="daydropdown" ></select>
<select name="monthdropdown" id="monthdropdown"></select>
<select name="yeardropdown" id="yeardropdown"></select>
<script type="text/javascript">
populatedropdown("daydropdown", "monthdropdown", "yeardropdown")
Javascript code:
<script type="text/javascript">
var monthtext=['Jan','Feb','Mar','Apr','May','Jun','Jul','Aug','Sept','Oct','Nov','Dec'];
function populatedropdown(dayfield, monthfield, yearfield)
{
var today=new Date()
var dayfield=document.getElementById(dayfield)
var monthfield=document.getElementById(monthfield)
var yearfield=document.getElementById(yearfield)
for (var i=1; i<=31; i++)
dayfield.options[i]=new Option(i, i)
dayfield.options[today.getDate()]=new Option(today.getDate(), today.getDate(), true, true) //select today's day
for (var m=0; m<12; m++)
monthfield.options[m]=new Option(monthtext[m], monthtext[m])
monthfield.options[today.getMonth()]=new Option(monthtext[today.getMonth()], monthtext[today.getMonth()], true, true) //select today's month
var thisyear=1999
for (var y=0; y<45; y++){
yearfield.options[y]=new Option(thisyear, thisyear)
thisyear+=1
}
yearfield.options[0]=new Option(today.getFullYear(), today.getFullYear(), true, true) //select today's year
}
</script>
try
if(isset($_GET['sort'])) {
echo $_GET['sort'];
}
and get selected index
<option value="inc_patientName" <?php if (isset($_GET['sort']) && $_GET['sort'] == "inc_patientName") echo 'selected="seleceted"'; ?>>Patient Name</option>
and so on for all options values match
For 2nd dropdown:-
while ($row = mysql_fetch_array($result)) {?>
<option value="<?php echo $row['ward_id'];?>" <?php if (isset($_GET['sort']) && $_GET['sort'] == $row['ward_id']) echo 'selected="seleceted"'; ?>><?php echo $row['ward_name'];?></option>
<?php }
use it like this... it myt work.
<select name="ward">
<?php
$sql = "SELECT ward_name,ward_id FROM ward_master";
$result = mysql_query($sql);
while ($row = mysql_fetch_array($result)) {
if ($_GET['ward']==$row["ward_id"]) {
echo '<option selected="selected" value='.$row["ward_id"].'>'.$row["ward_name"].'</option>';
} else {
echo '<option value='.$row["ward_id"].'>'.$row["ward_name"].'</option>';
}
}
?>
</select>
You can do something like this:
<select name="sort" >
<option value="inc_patientName"<?php if ($_GET['sort'] == 'inc_patientName') echo ' selected="seleceted"'; ?>>Patient Name</option>
<option value="inc_date"<?php if ($_GET['sort'] == 'inc_date') echo ' selected="seleceted"'; ?>>Date</option>
<option value="inc_status" <?php if ($_GET['sort'] == 'inc_status') echo ' selected="seleceted"'; ?>>Status</option>
<option value="inc_patientAge"<?php if ($_GET['sort'] == 'inc_patientAge') echo ' selected="seleceted"'; ?>>Age</option>
</select>
Try this:
Use this function in ur script:
function setday(id,elementname)
{
document.getElementById(elementname).value=id;
}
Use this in ur php form, Repeat the same code for year and month dropdowns:
if (isset($_GET['daydropdown']))
{
echo "<script type='text/javascript'>setday('".$_GET['daydropdown']."','daydropdown')</script>";
}
I am currently working with a dynamic dropdown menu(dependable select boxes). I am pulling the values straight from MySQL DB(if your curious here is how i have the DB SETUP). I am able to get the values of each table and display them accordingly. The problem I am having is echoing the SELECTED value of each selct box. I have a created JS function that will request postfile.php which will then echo the SELECTED value of each box. I am not getting anything echoed. I have checked with firebug but nothing is being posted.
How can I make this work? or Am I approaching this wrong? or Is there a better way? EXAMPLE
Working HTML/PHP
<?php

$list = $statement->fetchAll(PDO::FETCH_ASSOC);
} catch(PDOException $e) {
echo 'There was a problem';

Maybe you would like to use jQuery UI auto-complete. It is easier to use and less code. It has a remote data source also. Try this one, maybe this can solve your problem. http://jqueryui.com/demos/autocomplete/
Add on submit action to the form. In the function use the following:
var Myvar = $('#subc3 :selected').text();
