In this tutorial, I explore how to convert a select dropdown into a text input field in a CodeIgniter or PHP application. This process is ideal when I need a more flexible input option, allowing users to type in a custom value.
Step-by-Step Guide
Original Dropdown Example: Using a standard select dropdown, the options could be cars (e.g., Volvo, Audi). This setup works for predefined choices but limits user input.
Transformation to Text Field: To convert this to a text input, I start by replacing the <select> tag with an <input type="text">. I ensure that class names, IDs, and form controls match the original setup, as many applications rely on proper naming conventions for form elements.
Adjusting PHP Code: The original dropdown might be populated using PHP and connected to a database. However, when I convert it to a text field, the input won’t be tied to predefined values from the database. Instead, users can freely input any value.
Important Considerations: I make sure to preserve essential attributes like name, class, and ID, as these are crucial for the form to function correctly in PHP applications. The form will still work without a database, but values will be manually entered by the user.
Code:
<select class="form-control select" name="city" id="city">
<option value=""><?php echo $language['lg_select_city'];?></option>
</select>
<input type="text" class="form-control" name="city" id="city" value="<?php echo $profile['city'];?>">
Conclusion
This simple approach allows for flexibility in cases where a dropdown isn’t the best option. For instance, in fields like “name” or custom user inputs, converting a select dropdown to a text field is a practical solution.
