my controller
<?php namespace App\Http\Controllers;

DB::table('employer')->insert($data);
}
}
I created ID column and set auto increment it in Mysql.I want to display max value(4) on Id text-field of customer registration form.
with mysql you can do this
SELECT AUTO_INCREMENT
FROM information_schema.TABLES
WHERE TABLE_SCHEMA = "databaseName"
AND TABLE_NAME = "tableName"
for laravel
$table = DB::select("SELECT AUTO_INCREMENT FROM information_schema.TABLES WHERE TABLE_SCHEMA = 'databaseName' AND TABLE_NAME = 'tableName'");
if (!empty($table)) { echo $table[0]->AUTO_INCREMENT; }
If you are asking how to show the id of a Model, first in your controller, make a collection query like:
$posts= Post::all();
return view(view.post)->withPosts($posts);
and then on your blade file, make a foreach to iterate through all the posts:
#foreach ($postsas $post)
<p>This is ID number {{ $post->id }}</p>
#endforeach
If you are asking how to manually auto increment a certain column, this is the code I used to manually make an auto-increment column (form_counter) starting with value of 1. Basically, I check if there is an existing record, if there is none, the first record for the form_counter column is 1. If it is existing, add 1 to the most current value in the column.
$lastValueCollection = Post::where('formId', $request->inputFormId)->orderBy('Term', 'desc')->first();
$form_counter = 1;
if(isset($lastValueCollection->form_counter)){
$form_counter = $lastValueCollection->form_counter + 1;
}
$data = array('E_ID'=>$ID,....., 'Client_ID'=>$form_counter);
DB::table('employer')->insert($data);
This is not exact but I hope this gives you an idea.
on your schema builder: $table->increments('yourPrimaryKey');
example :
Schema::table('users', function (Blueprint $table) {
$table->increments('id');
});

I have an HTML form that I wanna to use to generate dynamically ADD more input fields:
<div class="row cloneDefault">
<div class="form-group col-md-1">
<br />
<h4 style="text-align:right">1.</h4>
</div>
<div class="form-group col-md-1">
<label class="control-label">First name</label>
<input type="text" value='' class="form-control" id="FirstnameField"/>
</div>
<div class="form-group col-md-2">
<label for="sname" class="control-label">last name</label>
<input type="text" value='' class="form-control" id="lastnameField"/>
</div>
<i class="remove">remove</i>
</div>
<form class="frm">
<div class="row">
<div class="form-group col-md-1">
<br />
<h4 style="text-align:right">1.</h4>
</div>
<div class="form-group col-md-1">
<label for="fname" class="control-label">First name</label>
<input type="text" value='' class="form-control" id="fname"/>
</div>
<div class="form-group col-md-2">
<label for="sname" class="control-label">last name</label>
<input type="text" value='' class="form-control" id="sname"/>
</div>
<i class="remove">remove</i>
</div>
<i class="add"> Add </i>
</form>
<style>
.cloneDefault{
display: none;
}
</style>
And JS to handle adding input fields dynamically:
$(document).ready(function() {
$(".add").click(function() {
$(".cloneDefault").clone(true).insertBefore(".frm > div:last-child");
$(".frm > .cloneDefault").removeClass("cloneDefault");
return false;
});
$(document).on('click', '.remove', function() {
$(this).parent().remove();
});
});
Now, I can easily retrieve text value from an input field by element id and then query cloud firestore:
const first_name = document.querySelector('#fname').value;
const last_name = document.querySelector('#sname').value;
firebase.firestore().collection("users").add({
fame: first_name,
sname: last_name,
}).then(function () {
console.log("success");
})
.catch(function (error) {
console.log("error:", error);
});
But how to save dynamically generated input fields in JS and save them on cloud firestore? I realised that my code to generate dynamically added input data may be unsuitable if I'd like to use it afterwards. What I wanted to do is similiar as this . Any idea?
I want to be able to check two input field values (return and stakePlaced) e.g. 100 and 20
if the result field = win, then perform calculation: return (minus - ) stakePlaced and then display the result in another field called profit.
PHP is being used to pull data from table --- ignore the PHP code.
HTML
<div class="form-group">
<label for="stakePlaced">Stake Placed</label>
<input type="text" class="form-control mb-2" placeholder="stakePlaced" name="stakePlaced" value="<?php echo $stakePlaced ?>">
</div>
<div class="form-group">
<label for="result">Result</label>
<input type="text" class="form-control mb-2" placeholder="result" name="result" id="result" onchange="calcula" value="<?php echo $result ?>">
</div>
<div class="form-group">
<label for="return">Return</label>
<input type="text" class="form-control mb-2" placeholder="return" name="return" id="return" value="<?php echo $return ?>">
</div>
<div class="form-group">
<label for="return">Profit</label>
<input type="text" class="form-control mb-2" placeholder="profit" name="profit" id="profit" value="<?php echo $profit ?>">
</div>
JS
function calcula(){
$(document).ready(function(){
$("#result").keyup(function(){
if (this.value == "Win"){
var vreturn = document.getElementById('return').value;
var stake = document.getElementById('stakePlaced').value;
var result = parseFloat(vreturn)-parseFloat(stake);
var secresult = result.toFixed(2);
document.getElementById('profit').value = secresult;
}
});
});
window.onload = calcula;
Your math is unclear... I don't know how the value could be Win when dealing with numeric values... But that may be something out of scope.
To get the input values by the name (since there is no id), you can use attribute selectors.
See below... Type "Win" in the "Result" field (second). It will output "0.00" in the "Profit" field (last).
$(document).ready(function(){
$("#result").keyup(function(){
if (this.value == "Win"){
console.log("Win!");
var vreturn = $("[name='return']").val();
var stake = $("[name='stakePlaced']").val();
var result = parseFloat(vreturn)-parseFloat(stake);
var secresult = result.toFixed(2);
$("[name='profit']").val(secresult);
}
});
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class="form-group">
<label for="stakePlaced">Stake Placed</label>
<input type="text" class="form-control mb-2" placeholder="stakePlaced" name="stakePlaced" value="20">
</div>
<div class="form-group">
<label for="result">Result</label>
<input type="text" class="form-control mb-2" placeholder="result" name="result" id="result" value="100">
</div>
<div class="form-group">
<label for="return">Return</label>
<input type="text" class="form-control mb-2" placeholder="return" name="return" value="20">
</div>
<div class="form-group">
<label for="return">Profit</label>
<input type="text" class="form-control mb-2" placeholder="profit" name="profit" value="30">
</div>
And you don't need to have a $(document).ready(function(){ in a named function which runs at window.onload... ;)
I have a view that is modeled to functions which pass data through to a database. This is all working and I see the data coming back when called, but it is not pre-populating the fields in my view when it comes back. I've been banging my head for a while on this. Everything is modeled (from what I can tell) properly.
I have stepped through the JS code below in Chrome and see the data being assigned to my $scope variables from the data.XXX return.
But, after load finishes, it's not preselecting my radio button or populating the fields with the data. Any help greatly appreciated.
Here is the View:
<div class="notification-container">
<form name="notificationForm" class="form-horizontal" ng-submit="saveQrNotifications()">
<div class="list-unstyled">

<input id="voice" ng-model="NotificationMethods.NotificationMethodId" ng-change="notifyVisible()" name="voice" type="radio" ng-value="1003"> Voice<br>
<input id="nocontact" ng-model="NotificationMethods.NotificationMethodId" ng-change="notifyVisible()" name="nocontact" type="radio" ng-value="1000"> Do Not Contact<br>

Here is my controller:
DATA COMING FROM DB:
if (data.StatusCode == "SUCCESS") {
$scope.refill = data;
//$scope.deliverTypes = data.DeliveryTypes;
$scope.showError = false;
$scope.submitRefill = true;
$scope.findRefillStatus = userMessageService.QuickRefillMessage(data.Prescriptions[0]);
$scope.isRefillable = data.Prescriptions[0].IsRefillable;
$scope.prescription.noPrescription.$valid = true;
$scope.loading = false;
$scope.NotificationMethods.NotificationEmailAddress = data.NotificationEmailAddress;
$scope.NotificationMethods.NotificationMethodId = data.NotificationMethodId;
$scope.NotificationMethods.NotificationTextAreaCode = data.NotificationTextAreaCode;
$scope.NotificationMethods.NotificationTextPhoneNumber = data.NotificationTextPhoneNumber;
$scope.NotificationMethods.NotificationVoiceAreaCode = data.NotificationVoiceAreaCode;
$scope.NotificationMethods.NotificationVoicePhoneNumber = data.NotificationVoicePhoneNumber;
$scope.NotificationMethods.NotificationVoiceExtension = data.NotificationVoiceExtension;
}
Figured it out. I was declaring the controller on the view used in ng-include. Removing that and letting the view inherit controller from surrounding view solved issue.
I made a form in jQuery + Django which has only one input active and the others are read only. There is a button which when clicked activates all the input boxes and the whole form is then editable. However, before clicking the button only one input is there and I want to be able to submit the form in that state. But I want all the other values to be submitted too, as they are readonly that should not be a problem.
Here's my JS:
$('#addInventoryForm').on('submit', function(event) {
event.preventDefault();
$('#name').focus();
add_to_inventory();
});
function add_to_inventory() {
console.log("add to inventory is working!")
$.ajax({
url : "/new/item/add/",
type : "POST",
data : { upc : $('#upc').val(), name : $('#name').val(), qty : $('#qty').val(), add_qty : $('#add_qty').val(), reorder_qty : $('#reorder_qty').val(), dp : $('#dp').val(), mrp : $('#mrp').val(), supplier : $('#supplier').val() },
success : function(data) {
console.log(data);
$('#extra').html(data);
console.log("success");
}
});
}
The url in the above code points to the following view:
def NewItemAdd(request):
if request.method == "POST":
upc = request.POST['upc']
name = request.POST['name']
if 'qty' in request.POST:
qty = request.POST['qty']
add_qty = request.POST['add_qty']
reorder_qty = request.POST['reorder_qty']
dp = request.POST['dp']
mrp = request.POST['mrp']
if 'supplier' in request.POST:
supplier = Supplier.objects.get(name=request.POST['supplier'])
if 'qty' not in request.POST:
qty = 0
if 'supplier' in request.POST:
defaults = {'name': name, 'qty': int(qty) + int(add_qty), 'reorder_qty': reorder_qty, 'dp': dp, 'mrp': mrp, 'supplier': supplier, 'user': request.user}
else:
defaults = {'name': name, 'qty': int(qty) + int(add_qty), 'reorder_qty': reorder_qty, 'dp': dp, 'mrp': mrp, 'user': request.user}
inv, created = Item.objects.update_or_create(upc=upc, defaults=defaults)
supplier_list = Supplier.objects.all()
return render(request, "alpha/new-item-add.html", {'suppliers': supplier_list})
The template used with this view is as follows:
<div class="container">
<div class="form-group">
<label class="control-label col-xs-1" for="name">Name:</label>
<div class="col-xs-9">
<input type="text" class="form-control" id="name" name="name" placeholder="" tabindex="2"/>
</div>
</div>
<div class="form-group">
<label class="control-label col-xs-1" for="qty">Current Quantity:</label>

{% for supplier in suppliers %}
<option value="{{ supplier }}" {% if supplier.name == item.supplier.name %}selected{% endif %}>{{ supplier.name }}</option>
{% endfor %}
</select>
</div>
</div>
<div class="form-group">
<div class="col-xs-offset-1 col-xs-9">

I want to be able to submit the form when the inputs are readonly as well as when I click a button and activate all the inputs. Can anyone find anything wrong with the above code?
The edit button removes the readonly attribute from all the inputs of the form. So before submitting the form I trigger a click on the edit button. It's almost instantaneous and the problem is solved.
$("#edit").trigger("click");
I have to check validation on two fields with ng-change. The selected values cannot be same so i have implemented below logic but this function is not even being called. Its been hours and i cannot figure out what i am doing wrong. Please check if logic is being implemented correctly.
So far tried code....
main.html
<div class="panel-body">
<form name="addAttesForm" id="addAttesForm" novalidate k-validate-on-blur="false">
<div class="row">
<div class="form-group col-md-6">

<div class="col-md-8">

data-value-field="'id'" name="roleType"
k-option-label="'Select'"
k-data-source="roleTypeDataSource"
ng-model="attestorDTO.riskAssessmentRoleTypeKey"
id="roleType">
</select>
</div>
</div>
</div>
<div class="row">

main.js
$scope.validateProxy = function(startField, endField) {
console.log("calling validation...");
var isValid = ($scope.attestorDTO[startField]) <= ($scope.attestorDTO[endField]);
$scope.addAttesForm[endField].$setValidity('dateRange',isValid);
$scope.addAttesForm.$setValidity('dateRange',isValid);
};
Remove the readonly attribute. ng-change will not fire on the readonly input elements and the model should be changed via the UI not by the javascript code.
Try like this:
<input type="text" class="form-control" id="attestorWorker" required
ng-model="attestorDTO.attestorWorker" name="attestorWorker"
ng-change="validateProxy('attestorWorker','proxyWorker')"
ng-model-options="{updateOn: 'blur'}"
ng-click="openAttestorSearch()" />
<input type="text" class="form-control" id="proxyWorker" required
ng-model="attestorDTO.proxyWorker" name="proxyWorker"
ng-model-options="{updateOn: 'blur'}"
ng-click="openProxySearch()" ng-disabled="!attestorDTO.attestorWorker" ng-change="validateProxy('attestorWorker','proxyWorker')" />
