I have a search results page in a PHP site that returns a list of results. I now need to add a filter option to the search results page so that users can further refine the search result from some Select menu choices. The URL for the search results looks like this:
findProducts.php?action=searchAssets&orderNumber=xxxx&productName=zzz
and is performed from a GET request on the search form page.
I've added some filters using select menus like this:
<div class="panel panel-primary">
<div class="panel-heading">
<h3 class="panel-title">Filter By</h3>
</div>
<div class="panel-body">
<form class="form-horizontal" id="filter" action="filter.php" method="get" role="form">
<input type="hidden" name="action" value="filterSearch">
<div class="form-group">
<div class="col-sm-9">
<select class="form-control" name="productType" id="productType">
<option selected="selected">By Product Type</option>
<option value="Cars">Cars</option>
<option value="Trains">Trains</option>
<option value="Planes">Planes</option>
</select>
</div>
</div>
</form>
</div>
</div>
What I now need to happen, and not sure about how to do this, is that when the Select menu is modified that it performs the search again, e.g. the GET request would now be something like this:
findProducts.php?action=searchAssets&orderNumber=xxxx&productName=zzz&productType=Cars
if the user selected the Cars option from the select menu. I'm using PHP and Bootstrap so jQuery/PHP solutions can be used here.
Attach a on-chage event to your dropdown, then when triggered append it's value to the current url, and reload the page.
$(document).ready(function(){
$('#productType').change(function(){
window.location.href = window.location.href + '&productType=' + $(this).val();
});
});
this is what you need https://www.w3schools.com/php/php_ajax_database.asp
you can do even chained dropdowns. if you want to send more one param (to do WHERE something='a' AND b='c') to that php page use hidden form feilds and javascript.
Onn select "change" event, you can call a function which would do a ajax call to your search result url.. like this:
$("#productType").on('change', function(){
var product_type = $(this).val(); //selected product type
var your_search_url = "path/to/findProducts.php?action=searchAssets&orderNumber=xxxx&productName=zzz&productType="+product_type;
$.get(your_search_url, function(data, status){
// your code here to deal with the search results
});
});

Using the chosen lib I run into the following issue, you can reproduce it yourself by going to their show-and-tell-page:
https://harvesthq.github.io/chosen/
Steps to reproduce:
In their standard select section, select -any country you want- in both the standard dropdown and the chosen dropdown
Click 'fork on github'(or any link) to leave the page
Navigate back by hitting the back button in chrome
The standard dropdown shows you the previously selected country
The chosen dropdown is empty (but under the hood the value is selected, according to what I'm seeing with my form. It just is not showing)
So this leads to confusion. When the user would back and then go forward again by submitting the form(in my case) it would use another value than what is shown.
My form basically looks like:
<form id="myForm" action="${home}mySite/foo/bar" method="GET">
<select id="bar" name="barName" class="chosen-select">
<option value="a">foo 1</option>
<option value="b">foo 2</option>
<option value="c">foo 3</option>
<option value="d">foo 4</option>
</select>
<input type="submit" value="Continue"/>
</form>
If I remove the class="chosen-select" it works as I expect, but I lose chosen's nice search feature which I want. I've tried messing around with
<option value="a" selected="selected">Foo 1</option>
in the dropdown, but that doesn't help.
I've also tried changing the method="GET" to POST but there is no difference in behaviour. It still works as in the example link I provided.
The chosen lib generates the following in on the page:
<div class="chosen-container chosen-container-single" title="" id="parkingZoneOwner_chosen" style="width: 40%;"><a class="chosen-single">
<span>Foo 1</span>
<div><b></b></div>
</a>
<div class="chosen-drop">
<div class="chosen-search">
<input class="chosen-search-input" type="text" autocomplete="off">
</div>
<ul class="chosen-results"></ul>
</div></div>
But nothing about the generated html looks wrong to me, even after backing to the page.
I tried this in the js (events):
<script type="text/javascript">
$(function () {
$(document).ready(function () {
$(".chosen-select").chosen({
width: "40%",
search_contains: true
});
$('.chosen-select').on('chosen:ready', function(evt, params) {
$(".chosen-select").val("a");
});
});
});
$('.chosen-select').on('chosen:ready', function(evt, params) {
// alert("reached")
// I had really high hopes for this one:
$('.chosen-select').trigger('chosen:updated');
//Also tried this one:
$('#myForm')[0].reset();
});
Anyone know a way to fix this? Either the chosen dropdown needs to show what actually will be submitted in the form or the entire form maybe could be reset to default values somehow.
This solved it in the end, turning off autocomplete on the form.
<form id="myForm" action="${home}mySite/foo/bar" autocomplete="off" method="GET">
I don't know why this works.
I have a dropdown value out of forms and a table wih many rows to submit data.
What I'd like to do is during submit of each row submit also the getting value from the drop down list.
My table it's look like My code for dropdrown list is
<div class="panel-heading">
<label for="cat">Select a Category</label>
<select class="form-control" id='category' name="category" data-live-search="true" style="max-width:40%;" >
<?=$html?>
</select>
</div>
And the part for table rows is
<form id="sync-cat" action="controllers/product-add.php" target="_blank">
<input type="hidden" name="product" value="<?=$product['id']?>">
<button type="submit" class="btn btn-info btn-md">Sync Products</button>
</form>
I've tried with javascript copying selected value in hidden input but that run only for the first row. Also I've tried a hidden input above the dropdown list copying the select option but I didn't find a way to get value when I use submit button "Sync Products"
They should share the same form in HTML so that when the form is posted all available information is present in the form. Regardless your dropdown should also be in it's own form (if you don't put them in the same form) to be valid.
If you wanted to continue as is ignoring the proper things to consider above you could do it with something like this. This solution will make things a bit more complicated. I would recommend taking the above advice.
var form = document.getElementById('sync-cat')
form.addEventListener('submit', function(e) {
var valueFromDropDown = document.getElementById('category').value;
// Post the rest of the form
});

I am using SemanticUI for a dropdown list
<div class="ui dropdown">
<input type="hidden" name="gender">
<i class="dropdown icon"></i>
<div class="default text">Gender</div>
<div class="menu">
<div class="item" data-value="male">Male</div>
<div class="item" data-value="female">Female</div>
</div>
</div>
in the bottom of my page, I am initializing it as
jQuery(document).ready(function($) {
$('.ui.dropdown')
.dropdown()
;
});
The problem is that when a user selects an item, it does not update and it keeps showing the default value as selected.
But when I go to Chrome Console and execute the above code JQuery(document)..., then it works fine.
I am assuming it is due to that the initialization needs to execute after page loads completely. So, What I did is the following instead of the above:
window.addEventListener("load", function(){
jQuery(document).ready(function($) {
$('.ui.dropdown')
.dropdown()
;
});
});;
It worked. Dropdown list updates selection immediatly. However, when I click on Submit, I and page reloads, the selection is lost.
The drop down is being used as a filter to table. Having the selection gets lost on submit, makes filter unusable.
What is the best way to go around this.
Use AJAX to submit the form so the page doesn't refresh.
<select>
<option value="male">Male</option>
<option value="female">Female</option>
</select>
no extra js, css required,
edit: autocomplete attribute is not required because it is the default
I have the following code on another webpage on my site with a form (say on page index.html): JSFiddle
<select class="select form-control" id="dropdown" name="dropdown" onchange="showForm()">
i.e a dropdown form.
I want to have a link on another webpage that will go to this page, and have the "Sales" option already selected.
<option value="1">
Sales
</option>
from the drop down menu (instead of the current default option), how do I create this?
Query parameters can be used to achieve the result you want, but you will need to parse the query parameter manually on your current page, since there is no standard JavaScript method for doing it.
You can write the following code on your page to automatically select the option:
$(document).ready(function() {
// Parse your query parameters here, and assign them to a variable named `queryParams`
var option = queryParams.type;
$("#dropdown").val(option);
});
Now you can create an anchor with the URL of this page, e.g. http://yourpage.url?type=1, which will redirect to this page, and will automatically change the value of your dropdown accordingly.
You must add some kind of router functionality with Javascript in your site.
I think the simplest thing you could do it to have a script in that page that checks the url if it has say a #bar hash like so: http://yoursite.com/foo.html#bar.
<script>
// make sure you run this on DOM ready like in $.ready() in jQuery or in a script just before closing the body tag
if(window.location.hash === 'bar') {
// add the selected attribute to the <option> you want
}
</script>
Try with append() function of jquery .and pass this with in onchange function call .And also added with document.ready for create the link on document load with selected value
function showForm(that){
var s = $(that).children('option:selected').text()
$('#link_box').append(''+s+'</br>')
}
$(document).ready(function(){ // for window load
showForm($('select'))
})
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="form-group ">
<label class="control-label" for="dropdown">
What can we help you with?
</label>
<select class="select form-control" id="dropdown" name="dropdown" onchange="showForm(this)">
<option value="0" disabled>
Select an option

<option value="1" selected>

<!-- its a link append box-->

I have a project in which I must do something like this:
when a user's page loads, he gets a personalized select box (with some options generated by PHP for him) and then, when he changes the option, I must change the rest of the content (on the same page).
for example, let the select box for a kind of user be:
Main content
Tools
Now, my idea was to have a
<form action="processing.php">
<select name="choice" onChange="submit();"> etc. which should pass the user's choice to processing.php. The problem is, I want the first option to be automatically selected and the content for that option to appear when the page loads - somehow like the first option to be automatically submitted.
Also, different kind of users should get different options, and I thought I can use a single page to process these requests. Is this achievable?
Can you please help me with an idea on how to submit that form automatically with the first generated option? Thank you.
You can use the onChange Event of the selection. In the handler you can then do the redirect
let sel = document.getElementById('yourselect');
let form = document.getElementById('yourform');
sel.onchange = function() {
form.submit()
}
You can easily bind the select change with Javascript. Here is the example with jQuery:
$('#mySelect').on('change', function(){
// Do your staff
$('#myForm').submit();
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<form id="myForm">
<select id="mySelect" method="post" action="processing.php" name="select_name">
<option value="">Select One</option>
<option value="http://google.com">Google</option>
</select>
</form>
