I have a table in which there are 10 fields related to student skills i.e. skill_1, skill_2 etc, and I am saving these fields using form, now I want that, on the detail page, I have a diabled text field that displays the total numbers of skill that the user entered. so how can I do this as there are 10 fields, so how can I count these fields ?
<div class="fields">
<label class="field-label" for=skills">Total Skills</label>
<div class="controls">
<inputname="" type="text" value="<?php // Here I want to show the tatal number of skill that the users entered. ?>" disabled="">
</div>
</div>
e.g.
if we want to show the total number of posts then the code will be
$countposts = Posts::model->count();
echo $countpposts; // it will display the tatal number of posts.
but in my case there are 10 individual fields, and I want to show that in how much fields the skill is entered and how much is blank.
