I have foreach and inside foreach i have input like this:
<input type="text" id="text-title" name="article_title[{{$language->code}}]" value="{{ old('article_title[$language->code]') }}" class="form_input" />
Im trying to add old input like this but its not working. Any suggestion how can i use old for array?
Also i tried this but also not working:
<input type="text" id="text-title" name="article_title[{{$language->code}}]" value="{{ old('article_title.0') }}" class="form_input" />
I have validation only for first iteration if that means anything for you.
You should be able to access the index off of your language code:
value="{{ old('article_title.'.$language_code) }}"
you can use the old to return old value as an array
# old('article_title') => array
value="{{ old('article_title')[$language_code] ?? "" }}"

How would I avoid doing calculation for 3 inputs using Livewire and use JS instead, but still can bind the inputs and their new values with the component.
Example:
<input id="cash-price"
type="text"
wire:model="total_cache_price"
class="amount-credit">
<input id="deposit"
type="text"
wire:model="deposit"
class="amount-credit">
<input id="trade-in"
type="text"
wire:model="trade_in"
class="amount-credit">
I can easily do a simple calculation using JS, but the properties in Livewire component would still be empty or null after submitting the form. I am trying to avoid livewire requests for every input change.
Note: I understand the deferred updating in livewire, the problem is with the property values not changing.
I will show you an example in alpine js + livewire way.
Here I want to set value in two inputs from a selected option in select.
Please note that x-ref is used in alpine to directly access DOM elements without using getElementById.
<div x-data="{
from_date : #entangle('from_date').defer,
to_date : #entangle('to_date').defer,
dateChange(){
select = this.$refs.years;
this.from_date = select.options[select.selectedIndex].getAttribute('data-from');
this.to_date = select.options[select.selectedIndex].getAttribute('data-to');
},
resetFilters(){
this.net_balances = false;
}}">
<select x-ref="years" #change="dateChange()">
<option value="">Year</option>
#foreach ($years as $key => $year)
<option wire:key="{{ 'years'.$key }}" data-from="{{ $year->from_date }}" data-to="{{ $year->to_date }}" value="{{ $year->id }}">{{ $year->name }} </option>
#endforeach
</select>
<div>
<text type="date" x-model="from_date" />
</div>
<div >
<text type="date" x-model="to_date" />
</div>
I used laravel validator.
I have a form wih 2 fields
If i fill one field "NAME" and i leave the other "SURNAME" empty pressing SAVE button of the form appears required alert message on SURNAME but the name inserted in the NAME field became empty! And i think form send data anyway.why?I aspect that form doesn't send datas
In the value attribute of each input you need to echo old("the-input-name") so it can retain the previous input before the error
<input name="name" value="{{old('name')}}" class="" />
You should use old('NAME') to get the value of the field after the validation fails, blade example:
<input type="text" value="{{ old('NAME') }}" />
An example In case of update forms you should display the original value from the database unless there's an error:
<input type="text" value="{{ old('NAME') ?? $your_entry->value }}" />
Take a look at the documentation for more details
I am using same form for Create and Edit i have a Folder field and i want to set its value Inbox by default however if a user want to replace it with own folder he /she can replace

I want that Default value should not be show in Edit form it just show the name from Folder remember that i can't remove value="INBOX" because i need it i am using it as default value and i am using same form for Create and Edit
Thanks For Help
You Need to pass default value as
<input type="text" name="folder" value="{{isset($mbl->folder) ? $mbl->folder : 'INBOX' }}" class="form-control" />
Try This hope it will work
Simply use it as follows:
<input type="text" name="folder" value="{{$mbl->folder or 'INBOX' }}" class="form-control" />

I have a problem in populating edit form fields in my first Laravel 5.3 application. In examples I have found online, they have used Form facade to do it. However, I prefer to use plain html.
This is my controller action
public function edit()
{
$profile = Profile::find(Auth::user()->id);
return view('profile.edit', ['profile' => $profile]);
}
In my view file I have a form like this
<form method="POST" action="{{ url('profile/update') }}">
{{ csrf_field() }}
<input id="name" type="text" name="name" value="{{ old('name') }}">
...
</form>
Problem is, above input field is not populated with the value of the $profile->name.
I can get it to work, setting the value attribute like
{{ (old('name')) ? old('name') : $profile->name }}
Since I'm new to Laravel framework I want to know if there is a better way to do that.
Use old($key, $default). It will return $default if $key is not found.

I am writing the logic for an edit form and have some complications when displaying data in the inputs.
When I initially show the form, I show the records values like:
value="{{$dog->title}}"
Then when the form does not pass the validation I need to show the old input, so that user does not loose what he has already input. So I need to have a way to display old data like:
value="{{old('title')}}"
Because I need to input old data in case it exists, I ended up with this code:
value="{{$dog->title or old('title')}}"
And in controller I check if Request has old input, I assign the $dog var a null value.
I wanted to ask if that is considered an OK practice or is there a better and 'correct' way to do it?
Function old have default parameter if no old data found in session.
function old($key = null, $default = null)
You can replace expression in template with
value="{{old('title', $dog->title)}}"
I know this has already been answered but I thought I would leave a little snippet here for others in the future.
Setting old value on input as #ikurcubic posted can be used the same way on radio button or select:
<input type="text" name="name" value="{{ old('name', $DB->default-value) }}" />
Select option:
<option value="Jeff" {{ old('name', $DB->default-value) == 'Jeff' ? 'selected' : '' }}>Jeff</option>
Radio Button:
<input type="radio" name="gender" value="M" {{ old('name', $DB->default-value)== "M" ? 'checked' : '' }} />
Another way of doing it; write a small if statement to determine which value should be evaluated:
#php
if(old('name') !== null){
$option = old('name');
}
else{ $option = $database->value; }
#endphp
<select name="name">
<option value="Bob" {{ $option == 'Bob' ? 'selected' : '' }}>Bob</option>
<option value="Jeff" {{ $option == 'Jeff' ? 'selected' : '' }}>Jeff</option>
</select>
<input type="radio" name="gender" value="M" {{ $option == "M" ? 'checked' : '' }} />
<input type="radio" name="gender" value="F" {{ $option == "F" ? 'checked' : '' }} />
Setting old value of input with an array name e.g name="name[]":
<input type="text" name="name[]" value="{{ old('name.0) }}" />
This will give you the old value of the input with an index of 0.
I have tested this and it works.
Another way to do that is get the data from the dog class, like this:
value="{{old('title') ?? $dog->title }}"
Why? Because old() is for validation; when you fail validation, the input will remain available in the field. In the case where validation hasn't fired yet, value will be filled with $dog->title.
I solved that issue in my application
if you want to get old previous inserted value in input you should try this one
I did like this.
function SaveData(Request $request)
{
$sValidationRules = [
'firstname' => 'required',
'lastname' => 'required',
'email' => 'required',
'phone' => 'required',
];
$validator = Validator::make($request->all(), $sValidationRules);
if ($validator->fails()) // on validator found any error
{
// pass validator object in withErrors method & also withInput it should be null by default
return redirect('Your Route Hare')->withErrors($validator)->withInput();
}
Employee::create($request->all());
return redirect(' your route hare ');
}
& after then get old data in input field value like this using {{ Request::old('firstname') }}
Happy Coding. :)
<input type="text" name="firstname" id="firstname" value="{{ Request::old('firstname') }}" class="form-control" placeholder="First Name">
Old Data: input type text | phone | number | ...
<input type="text" name="my_text" value="{{old('my_text')}}">
Old Data: input type checkbox | radio
<input type="checkbox" {{ old('my_checkbox') == 'on' ? 'checked' : '' }} name="my_checkbox">
There is nothing wrong with the way you are doing things as Laravel gives multiple ways to handle the situation you're describing.
What I would suggest is using the Laravel Collective Form and HTML packages to build your form. This package will automatically handle binding old request values to your form if validation fails
