How to retrieve the last inserted id from another method inside same class?

I have two methods inside Home class called addProperty and uploadImages.
I'm calling the uploadImages() method from the jquery dropzone to post the images and addProperty() for inserting the form inputs into the database.
I want to pass the last inserted Id from the addProperty method to uploadImages to save the image details into the database.

I want to insert the image details into the table called tbl_property_images
File Upload working
Form inputs also successfully inserted
Problem :
I need to insert image details to the table with the propertyid, The propertyid is the last inserted id we get from the $result variable in addProperty method.

Solution 1
Create a procedure which will insert the record and return the id of the inserted record.
Solution 2
Create a procedure which will insert all the data to the respective tables and return success or failure.

how to add multi captcha in same page and check both checkbox its fill

I have two forms on a single page, one of them is a login form and the other is a register form (two tabs) and I want to check the the captchas, but when I click the check captcha from register form I can't login.
The login form:
HTML:
<div id="loginUserTab" class="tab-pane fade">
<form>
<div class="form-group login-width-100">
<label for="id_number" class="m-rtl-label"><span class="requiredMark">*</span>passport number:</label>
<input type="text" class="form-control" id="pNo" name="pNo" data-validetta="required,minLength[10],maxLength[10]" lang="fa" style="text-align: left;">
</div>
<div class="form-group login-width-100">
<label for="mNumber" class="m-rtl-label"><span class="requiredMark"></span> telephone :</label>
<input type="text" class="form-control" id="tNumber" name="tNumber" data-validetta="required,minLength[11],maxLength[11]" lang="fa" style="text-align: left;">
</div>
<div class="form-group" style="float:right;padding-right: 20px;">
<div class="g-recaptcha" data-sitekey="...."></div>
</div>
<div class="form-group login-width-100">
<button type="submit" class="btn btn-primary colorGreenBTN">login</button>
</div>
</form>
</div>
JS:
var v = grecaptcha.getResponse();
if (v.length == 0) {
alert("fill the form");
return;
} else if (!$("#Terms").prop("checked")) {
alert("check the rules");
}

Simplest Way to validate as much g-captcha validate
Hope you have included api.js before </head> tag as per below
<script src="https://www.google.com/recaptcha/api.js?onload=CaptchaCallback&render=explicit"></script>
Your HTML Code looks like below
<div class="g-recaptcha-contact" data-sitekey="Your Site Key" id="RecaptchaField2"></div>
<input type="hidden" class="hiddenRecaptcha" name="ct_hiddenRecaptcha" id="ct_hiddenRecaptcha">
<div class="g-recaptcha-quote" data-sitekey="Your Site Key" id="RecaptchaField1"></div>
<input type="hidden" class="hiddenRecaptcha" name="qt_hiddenRecaptcha" id="qt_hiddenRecaptcha">
After you add this code in footer with tag
var CaptchaCallback = function() {
var widgetId1;
var widgetId2;
widgetId1 = grecaptcha.render('RecaptchaField1', {'sitekey' : 'Your Site Key', 'callback' : correctCaptcha_quote});
widgetId2 = grecaptcha.render('RecaptchaField2', {'sitekey' : 'Your Site Key', 'callback' : correctCaptcha_contact});
};
var correctCaptcha_quote = function(response) {
$("#qt_hiddenRecaptcha").val(response);
};
var correctCaptcha_contact = function(response) {
$("#ct_hiddenRecaptcha").val(response);
};
And Last easy step for developer add Jquery Validation as per below
$("#form_id").validate({
ignore: [],
rules: {
ct_hiddenRecaptcha: { required: true, },
qt_hiddenRecaptcha: { required: true, },
},
});
If you have same class for both the forms, you can use it to validate above.

AJAX call PHP same page and reload option values

i have an html form with a date input and a multiselect.
When loading page I load the options of the multiselect through a php function.
What i want to do is to capture onChange event of the date input with a js script and launch the php script to reload the option values of the select using the new date.
This is the php code
<?php
//DEFINE
$dateMinimumInput = "";
// Handle AJAX request for changing DateMinimumInput(start)
if(isset($_POST['ajax']) && isset($_POST["dateMinimumChanged"]) ){
echo "Inside function dateMinimumChanged: " .$_POST['dateMinimumChanged'];
$dateMinimumInput = verify_input($_POST['dateMinimumChanged']);
}
$stationList = selectStations($dateMinimumInput); ?>
This is the javascript
<script>
$(document).ready(function(){
$("#dateMinimumInput").change(function(){
//Selected value
inputValue = $(this).val();
console.log(inputValue);
$.ajax({
type: 'POST',
url: '',
data: {ajax: 1, dateMinimumChanged: inputValue},
success: function(data){
console.log('works');
console.log(data);
$('body').append(response);
},
error: function(){
alert('something went wrong');
}
});
});
});
</script>
and this is the html form
<form class="" role="form" action="<?php echo htmlspecialchars($_SERVER["PHP_SELF"]);?>" method="post">
<div class="row">
<div class="col-md-6">
<div class="form-group form-row">
<label for="dateMinimumInput" class="col-form-label col-sm-4">Date Minimum:</label>
<div class="col-sm-8">
<div class="form-group">
<input type="date" class="form-control <?php if ( $dateMinimumInputErr !== "") { echo 'is-invalid'; }?>" id="dateMinimumInput" name="dateMinimumInput" placeholder="Enter date minimum" value="<?php echo $dateMinimumInput;?>">
<div class="invalid-feedback"> <?php if ( $dateMinimumInputErr !== "") { echo 'Please, ' .$dateMinimumInputErr; } ?> </div>
</div>
</div>
</div>
</div>
</div>
<div class="row">
<div class="col-md-6">
<div class="form-group form-row">
<label for="stationInput" class="col-form-label col-sm-4">Station:</label>
<div class="col-sm-8">
<select id="stationInput" name="stationInput[]" class="form-control" multiple>
<?php
foreach($stationList as $station){
if($station['numberofmeasurements'] == 0){
echo '<option disabled="true" value="'.$station['id'] .'">'.$station['location'] .' (' .$station['numberofmeasurements'] .') </option>';
}else{
echo '<option value="'.$station['id'] .'">'.$station['location'] .' (' .$station['numberofmeasurements'] .') </option>';
}
}
?>
</select>
</div>
</div>
</div>
<div class="row">
<div class="col-md-12 text-right">
<button id="submit" name="submit" type="submit" class="btn btn-primary">Search</button>
</div>
</div>
</form>
The fragments of code are all from the same page.
The problem is that when I change the date, the javascript captures the event but the PHP script is not executed and the options are not reload.
Any help about what I'm doing wrong?
Thank you

How to specify minlength in jquery?

If the status value is completed then comment field is required is working good.But the problem is, I want to specify comment field is required for minimum of 50 character.
The Below code: index.php
<!-- Select Basic -->
<div class="form-group">
<label class="col-md-4 control-label" for="selectbasic">Status</label>
<div class="col-md-4">
<select id="status" name="status[]" class="form-control" >
<option value="Pending">Pending</option>
<option value="Work in process">Work in process</option>
<option value="Completed">Completed</option>
</select>
</div>
</div>
<!-- Text input-->
<div class="form-group">
<label class="col-md-4 control-label" for="textinput">Comment</label>
<div class="col-md-4">
<input id="commentss" name="comment[]" type="text" placeholder="" class="form-control input-md" />
</div>
</div>
<div class="col-md-8 col-sm-12 col-24">
<div class="input_fields" style="color:black">
<button class="add_field btn " onclick="incrementValue()" >Add More</button>
<div>
<input type="text" name="mytextt[]" hidden="" ></div>
</div>
</div>
Javascript
<script type="text/javascript">
$(document).ready(function () {
$("#status").click(function () {
if ($("#status").val() == "Completed") {
$("#commentss").attr("required", "required");
}
else
$("#commentss").attr("required", false);
});
});
</script>

Use length to find the length of the string
if($('#commentss').val().length < 50){
alert("Please enter 50 characters atleast");
} else {
//submit
}

For this please use below code :
<script type="text/javascript">
$(document).ready(function () {
$("#status").click(function () {
var commenttext = document.getElementById('commentss').value;
if (commenttext.length < 50)
{
alert("Please Enter minimum 50 character!")
}
else
{
//Add code
}
});
});
</script>

In Jquery ...
For Dynamic Tracking ...
(You can use blur or keyup even too.)
$(function() {
//disable submit if you want to
$('#commentss').on('input', function(e) {
if(this.value.length >= 50) {
//success
} else {
//fail?
}
});
});
To Validate on Click only ...

You should change selectbox's name attribute with value
<select name="job_est">
<option value="select">--SELECT--</options>
<option value="job">Job</option>
<option value="est">Estimation</option>
</select>
and in your javascript, it should be
if (job_est.val() == 'select') {
job_est.addClass('hightlight');
return false;
}
