This isn't a Laravel specific problem. You are taking about DOM manipulation and so you best bet is to use jQuery or Vuejs or even vanilla Javascript if you so choose. Basically, you will write a script to watch for when your <select> changes, and then based on it's new value, show the part of the form you want.
Keep in mind that Laravel is a backend framework and so the user will never interact with it on a page. After a page loads, Laravel has done all it can do until another request is made. This is why Javascript was born - to let the user change things without reloading the page.

I have two almost identical forms. One is meant to edit an item, and the other is meant to create an item. For some reason, the create-form does not react at all to submit button clicks, while the edit/update form works exactly as expected. I can not find any differences between the two that should result in this behavior.
I am as sure as I can be that this has nothing to do with back end. I have monitored network activity, ant the submit button for the create-form does not activate any kind of network activity at all.
Working update form:

Here how to use it according to its GitHub
I already install the package:
Use Opengraph
$data = OpenGraph::fetch("http://www.addemyplus.com/blogs/my-faith-for-your-love");
that may return an array:
{"type":"website","title":"My Faith For Your Love","description":"","image":"http:\/\/www.addemyplus.com\/images\/frontend_images\/blogs\/medium\/57670.jpg"}
My problem is how can I use it on my blade that whenever I type a link in the form it will fetch the Og data of that site.
and show below the image and description
I have this code on form:
<form action="{{route('store_post_path')}}" method="POST">
{{csrf_field()}}
<div class="form-group">
<label class="sr-only" for="title">title</label>
<input type="text" class="form-control" name="title" placeholder="Your Post Title or Question">
</div>
<div class="form-group">
<label class="sr-only" for="post">post</label>
<textarea class="form-control" name="post_content" id="post_content" rows="3" placeholder="Briefly explain your question or Your Post Content"></textarea>
</div>
<div class="tab-pane fade" id="images" role="tabpanel" aria-labelledby="images-tab">
<div class="form-group">
<div class="custom-file">
</div>
</div>
<div class="py-4"></div>
</div>
<div class="btn-toolbar justify-content-between">
<div class="btn-group">
<button type="Submit" class="btn btn-primary">Share your Post</button>
</div>
</div>
</form>
How can I use the code to fetch the Og property of the link? I want to view the image and title of the link below before submitting my post.. Please show some tutorial sites for this.
Get the link from the form in post content. You can do it using regex.
function getUrl($string)
{
$regex = '/https?\:\/\/[^\" ]+/i';
preg_match_all($regex, $string, $match);
return ($match);
}
$url = getUrl($string)
If there are any links in post content you will get array of links.
Use OpenGraph::fetch($url) to fetch the OG data of the url. That you can show in the view.

First thing first. You need to change queries.
Company::where(‘status’, 0)->get();
And next you missed the tailing get() in the next dropdown.
And why are you not using relationships to query?
Like Muhammad Naumann already said you have to use the get() method to get the actual data:
Company::where(‘status’, 0)->get();
On the company select field you could add an event listener like onChange. In this listener you run a ajax get request to fetch the dealerships for the selected company.
I figured it out with Ajax.
Create a custom function in controller file. In this case Branch controller, this function contains query builder to retrieve the data
Write Ajax, in the index file, the dealership dropdown is hidden default when you select the company the dropdown will show corresponding data.

Branch Controller File With a custom function
public function filter_dealer(Request $request)
{
$company_id=$request->input('option');
$dealership=DB::table('dealerships')->select('dlr_id','name')->where([['comp_id','=',$company_id],['status','=','0']])->get();
return response()->json($dealership);
}
Route File
Route::post('filter_dealer', 'BranchController#filter_dealer')->name('filter_dealer');
If you want to dynamically change the contents of dealership dropdown, on the event of changing the company dropdown, you should use javascript, jquery or similar javascript framework, because PHP is a server side scripting language and require page refresh to change the contents of a web page.
I'm trying to edit some database record based on an ID that I'm saving into a button value.
#foreach ($employment as $empl)
<button data-toggle="modal" data-target="#edit-empl" href="#edit-empl" class="btn btn-default editbtn-modal" value="{{ $empl->id }}" type="button" name="editbtn">Edit</button>
<h3 class="profile-subtitle">{{ $empl->company }}</h3>
<p class="profile-text subtitle-desc">{{ $empl->parseDate($empl->from) }} - {{ $empl->parseDate($empl->to) }}</p>
#endforeach
As you can see here, I have an edit button with an id attached.
When I click edit I open a modal window to edit the fields and later on submit the form.
The thing is, I'm not sure how to get that id from the button into the modal window so I can compare the values and display the correct fields..
<form class="app-form" action="/profile/employment/edit/{id}" method="POST">
{{ csrf_field() }}
<input class="editID" type="hidden" name="editID" value="">
#foreach ($employment as $empl)
#if ($empl->id == buttonidhere)
<div class="form-group">
<label for="company">Company:</label>
<input type="text" name="company" value="{{ $empl->company }}">
</div>
<div class="form-group">
<label for="month">From:</label>
<input type="date" name="from" value="{{ $empl->from }}">
</div>
<div class="form-group">
<label for="to">To:</label>
<input type="date" name="to" value="{{ $empl->to }}">
</div>
#endif
#endforeach
<div class="row">
<div class="col-sm-6">
<input type="submit" class="btn btn-primary profile-form-btn" value="Save Changes">
</div>
</div>
</form>
I was able to pass the button value into the modal using javascript.. I put it into a hidden input but that doesn't help me at all because I can't get the input value in order to compare the values..
Solution 1: Using ajax
Step 1: Create a route in laravel which will return a JSON object containing employing data of requested employee.
For e.g,
/profile/employment/data/{empl_id}
Will get you employement data of id empl_id.
Step 2: Change your form as below
<form class="app-form" action="/profile/employment/edit/{id}" method="POST">
<input class="editID" type="hidden" name="editID" value="">
<div class="form-group">
<label for="company">Company:</label>
<input type="text" name="company" value="">
</div>
<div class="form-group">
<label for="month">From:</label>
<input type="date" name="from" value="">
</div>
<div class="form-group">
<label for="to">To:</label>
<input type="date" name="to" value="">
</div>
<div class="row">
<div class="col-sm-6">
<input type="submit" class="btn btn-primary profile-form-btn" value="Save Changes">
</div>
</div>
</form>
Step 3: Use javascript(jQuery) to get the data using ajax and load it into the form in modal.
jQuery code:
$(document).on("click", ".editbtn-modal", function() {
var id = $(this).val();
url = "/profile/employment/data/"+id;
$.ajax({
url: url,
method: "get"
}).done(function(response) {
//Setting input values
$("input[name='editID']").val(id);
$("input[name='company']").val(response.company);
$("input[name='to']").val(response.to);
$("input[name='from']").val(response.from);
//Setting submit url
$("modal-form").attr("action","/profile/employment/edit/"+id)
});
});
Solution 2: Using remote modal
Step 1:
Create another blade file for eg. editEmployee.blade.php and add the above form in it.
<form class="app-form" id="modal-form" action="/profile/employment/edit/{{ $empl->id }}" method="POST">
{{ csrf_field() }}
<input class="editID" type="hidden" name="editID" value="{{ $empl->id }}">
<div class="form-group">
<label for="company">Company:</label>
<input type="text" name="company" value="{{ $empl->company }}">
</div>
<div class="form-group">
<label for="month">From:</label>
<input type="date" name="from" value="{{ $empl->from }}">
</div>
<div class="form-group">
<label for="to">To:</label>
<input type="date" name="to" value="{{ $empl->to }}">
</div>
<div class="row">
<div class="col-sm-6">
<input type="submit" class="btn btn-primary profile-form-btn" value="Save Changes">
</div>
</div>
</form>
Step 2: Create a controller which would return the above form as HTML.
Tip: use render() function. example
Step 3: load the form into modal window before showing using javascript(jQuery)
considering your modal id is "emp-modal"
$(document).on("click", ".editbtn-modal", function() {
var id = $(this).val();
url = "/profile/employment/data/"+id;
$('#emp-modal').modal('show').find('.modal-body').load(url);
});
One solution would be to send the details you want the same way you send the id to the modal.
and the proper way to send variables to modal is to include this in the button that opens modal:
data-variablename="{{$your-variable}}"
use this jQuery to get the values of your variables to modal. where edit-empl is the id of your modal and data-target of your button
$('#edit-empl').on('show.bs.modal',function (e) {
var variablename= $(e.relatedTarget).data('variablename');
$(e.currentTarget).find('input[id="yourinputID"]').val(variablename);
Here my code consists 2 fields(1.select field, 2.input filed),i am displaying data into these fields based on id's (using json data through ajax call)like ($("#allergictoId").val(data.allergy.allergicTo1)).Now my requirement changed like if i click on button (save and add allergy)the copy of that is added to previous code.Once he added clones and clicks on save the entire data will saved on database.Now he clicks again edit i can display the entire data with clones jsp code.Here is my jsp code
<div id="divHideAllergies" class="clone">
<div class="copy">
<div class="col-md-12">
<div class="portlet box carrot ">
<div class="portlet-title">
<div class="caption">
<i class="fa fa-medkit"></i> Allergies
</div>
</div>
<div class="portlet-body form">
<div class="form-body">
<div class="form-group">
<label class="control-label col-md-3">Allergy Type:</label>
<div class="col-md-9">
<div class="input-group">
<span class="input-group-addon"><i class="fa fa-medkit"></i></span>
<select class="form-control" id="allergy_type">
<option selected value="">--Select One--</option>
<option value="Drug">Drug</option>
<option value="Environmental">Environmental</option <option value="Food">Food</option>
</select>
</div>
</div>
</div>
<div class="form-group">
<label class="control-label col-md-3">Allergic to:</label>
<div class="col-md-9">
<div class="input-group">
<span class="input-group-addon"><i class="fa fa-medkit"></i></span>
<input type="text" class="form-control" name="first name" id="allergictoId"/>
</div>
</div>
</div>
</div>
</div><a class="btn btn-lg green pull-right" id="addallergy">Save and Add Allergy <i class="fa fa-plus"></i></a>
<a class="btn btn-lg red" id="removeallergy"><i class="fa fa-times"></i> Cancel</a>
</div>
</div>
</div>
</div>
</div>
I am not sure I can understand your question at 100% but here are some thoughts:
Check the "Processing JSON objects in JSP" question. Here they are using scriptlets but you can do basically the same with JSTL.
Your JSP seems to have lack of JSP code in it - it is just a HTML - and that's fine, but you can consider using JavaScript to process you JSON response since it is so much natural (at least to me).
