Send Data from Disabled HTML Input Field

If you want to disable an input field and but still post it’s data to a database via a back end programming language like PHP, give it the readonly attribute i.e.

<input name="Percentage" readonly="readonly" type="textbox" value="100" />

If assigned the disabled attribute, then it will not be able to post data.

What if you are working with a <textarea> element?

<textarea id="description-text" class="form-control" name="description_change" rows="5" required readonly><?php echo set_value('description_change');?></textarea>
