Enhancing Date Input Fields with HTML inputs Manipulation for Improved Web Functionality.
we focused on date input fields through out this article.
HTML date input fields are useful, but with a little manipulation, you can significantly improve web functionality and simplify the date validation process. In this guide, we’ll explore how to manipulate HTML date input fields to create dynamic, user-friendly date selection options. This method enhances the user experience and streamlines date validation in your web applications.
Why Manipulate HTML Date Input Fields?
Manipulating HTML date input fields offers several advantages:
- Simplicity: It’s a more straightforward and faster approach compared to using date pickers or select option input fields.
- Customization: You have greater control over the date format and the range of dates available for selection, such as limiting the number of years or months in the dropdown.
- Enhanced Security: By customizing date inputs, you can reinforce security measures in your application, aligning with evolving web security standards.
The Technologies Used
This project utilizes the following programming languages and frameworks:
- PHP 8.1
- HTML5 and CSS3 (Bootstrap 5.2)
- jQuery 3.06 (JavaScript)
- A dash of AJAX
How We Manipulate HTML Date Input
Let’s dive into the details of how we manipulate HTML date input fields to create a more interactive and user-friendly experience.
Creating the Date Input Field
Before you begin, create an index.php file in your project’s root folder (e.g., in XAMPP). In this file, we’ll build a dynamic Bootstrap dropdown for date selection.
Adding Bootstrap CSS and JS
Head over to the Bootstrap documentation (https://getbootstrap.com/docs/5.2/getting-started/introduction/) and include the Bootstrap CSS and JS via a Content Delivery Network (CDN). This will ensure that your dropdown styles and functionality work smoothly.

Now, let’s create dynamic Bootstrap dropdowns for day, month, and year.
Day Parameter:
<div class="input-group">
<button type="button" class="btn btn-outline-secondary dayvalue">Day</button>
<button type="button" class="btn btn-outline-secondary dropdown-toggle dropdown-toggle-split" data-bs-toggle="dropdown" aria-expanded="false">
<span class="visually-hidden">Toggle Dropdown</span>
</button>
<ul class="dropdown-menu">
<?php
$days = range(1, 31);
foreach($days as $day){
$day = str_pad($day, 2, '0', STR_PAD_LEFT);
echo '<li><a class="dropdown-item myday" href="'.$day.'">'.$day.'</a></li>';
}
?>
</ul>
</div>Month Parameter:
<div class="input-group">
<button type="button" class="btn btn-outline-secondary monthvalue">Month</button>
<button type="button" class="btn btn-outline-secondary dropdown-toggle dropdown-toggle-split" data-bs-toggle="dropdown" aria-expanded="false">
<span class="visually-hidden">Toggle Dropdown</span>
</button>
<ul class="dropdown-menu">
<?php
$months = range(1, 12);
foreach($months as $month){
$month = str_pad($month, 2, '0', STR_PAD_LEFT);
echo '<li><a class="dropdown-item mymonth" href="'.$month.'">'.date('F', mktime(0, 0, 0, $month, 10)).'</a></li>';
}
?>
</ul>
</div>Year Parameter:
<div class="input-group">
<button type="button" class="btn btn-outline-secondary yearvalue">Year</button>
<button type="button" class="btn btn-outline-secondary dropdown-toggle dropdown-toggle-split" data-bs-toggle="dropdown" aria-expanded="false">
<span class="visually-hidden">Toggle Dropdown</span>
</button>
<ul class="dropdown-menu">
<?php
$currentyear = idate('Y');
$yearend = $currentyear - 7;
$yearstart = $yearend - 90;
$years = range($yearstart, $yearend);
foreach($years as $year){
echo '<li><a class="dropdown-item myyear" href="'.$year.'">'.$year.'</a></li>';
}
?>
</ul>
</div>JavaScript and jQuery Integration
To make our date inputs dynamic, we’ll use JavaScript and jQuery. We’ll extract the selected day, month, and year values from the Bootstrap dropdowns and display them in the input fields.
Here’s the JavaScript code for handling date selection and submission:
<script>
$('.myday').click(function(e){
e.preventDefault(); // Disable the default link action
var day = $(this).attr("href");
$('.dayvalue').text(day);
$('.showlabel').removeClass('d-none');
});
$('.mymonth').click(function(e){
e.preventDefault(); // Disable the default link action
var month = $(this).attr("href");
$('.monthvalue').text(month);
$('.showlabel').removeClass('d-none');
});
$('.myyear').click(function(e){
e.preventDefault(); // Disable the default link action
var year = $(this).attr("href");
$('.yearvalue').text(year);
$('.showlabel').removeClass('d-none');
});
$(document).on('click', '.submit', function(){
var dayvalue = [];
var monthvalue = [];
var yearvalue = [];
$('.dayvalue').each(function(){
dayvalue.push($(this).text());
});
$('.monthvalue').each(function(){
monthvalue.push($(this).text());
});
$('.yearvalue').each(function(){
yearvalue.push($(this).text());
});
$.ajax({
url:"output.php",
method:"post",
data:{dayvalue:dayvalue, monthvalue:monthvalue, yearvalue:yearvalue},
success:function(data){
$('#input').removeClass('d-flex');
$('#input').fadeOut(function(){
$('#output').html(data);
});
}
});
});
</script>Processing Date Input with PHP
Now, let’s create an output.php file to process the manipulated HTML date inputs using PHP:
<?php
$dayvalue = $_POST["dayvalue"];
$monthvalue = $_POST["monthvalue"];
$yearvalue = $_POST["yearvalue"];
$dayvalue_clean = array();
$monthvalue_clean = array();
$yearvalue_clean = array();
if(isset($_POST["dayvalue"])){
for($count = 0; $count < count($dayvalue); $count++){
$dayvalue_clean = $dayvalue[$count];
$monthvalue_clean = $monthvalue[$count];
$yearvalue_clean = $yearvalue[$count];
}
echo $yearvalue[0].'-'.$monthvalue[0].'-'.$dayvalue[0];
}
?>Conclusion and Future Developments
