Wordpress Advanced Custom Fields within an if statement - php

Question

I'm trying to use ACF to output different salary amounts for a job listing board.
E.g:
Select box option in ACF for salary type ("competitive", per day, per annum etc). Looks like this:
Then I have conditional fields. So if "P.A" is selected it shows the P.A field:
I have a bunch of these conditional fields for the different select box options.
My question is:
How do I add these to an if statement so that the correct field is shown based on the content that was supplied?
E.g
if job_salary was selected as "competitive" =
echo "competitive"
else if job_salary was selected as "p.a" =
echo job_salary_singular
else if job_salary was selected as "p.a range" =
echo job_range_start " to " job_range_end
Hopefully this makes sense. This is the code I have at the moment, which just outputs the type of salary entered (e.g, competitive, P.A, Per Day Range) as text.

Answer 1

This approach should work. In my example, the main selector field where you choose if it's per annum pay, competitive, a range, etc., is called salary_type.
Then I've got per_annum. It appearing is conditional on 'Per Annum' being selected from salary_type. And finally per_annum_range_low and per_annum_range_high, both of which are conditional on 'Per Annum Range' being selected.
We can then test based on the salary_type selection to output the appropriate values and HTML. Alternatively, you could test for the existence of those fields. But I think this is a bit cleaner and allows you to skip adding an additional field for "Competitive".
PHP
<?php
if (get_field('salary_type')) { //first we check if the salary_type field exists.
$selection = get_field('salary_type'); //then we store its value as '$selection'
if ($selection === 'comp') { //we check which selection was made by looking at its label.
echo '<p>' . 'Competitive' . '</p>';
} else if ($selection === 'perannum') { //ACF allows you to store a selection as both a value (in this case, 'perannum') and a label ('Per Annum', which is what the user sees.)
echo '<p>' . get_field('per_annum') . ' per year</p>';
} else if ($selection === 'perannumrange') {
echo '<p>From ' . get_field('per_annum_range_low') . ' to ' . get_field('per_annum_range_high') . ' per year</p>'; //and then echo its output and any HTML markup you want.
} else {
echo '<p>No Salary Info Given.</p>'; //if they don't make a selection
}
}
?>
