Show / Hide custom php field with title

I want to display a custom field we have [using the Estatik wordpress real estate plugin] if the database field has a value and hide that if it is empty. I can get the field to display and hide if empty or filled out, but, I cannot display the text: "Year built" when the year is filled out:

<?php if( es_the_property_field('year-built1594411179f5f08c8ab6ff14') ): ?>
    <p>Year built: <?php es_the_property_field('year-built1594411179f5f08c8ab6ff14'); ?></p>
<?php endif; ?>

What can i change the code above to achieve:

If the year is filled out, I'd like it to display: Year built: 1994

If the year is left empty, i'd like the paragraph to not print at all

thanks in advance!

I am not familiar with the Estatik theme but I can tell you that you could test the content like this.

<?php 

$year_built = es_property_field('year-built1594411179f5f08c8ab6ff14');
if( $year_built != "" || $year_built != false ): ?>
    <p>Year built: <?php echo date("Y", strtotime ($year_built)); ?></p>
<?php endif; ?>

So the two things you were missing was a proper test in the if statement and then echoing out the year_built with the date format. Now this is assuming a few things.

  1. that es_the_property_field echos instead of returning which would be a very wordpress thing to do
  2. that removing the "the" from that function is the version of that function that returns instead of echos.

For most data in WordPress, there are the_[…]() and get_the_[…]() style functions. Generally the the_ functions will output the data, and the get_the_ functions will return. Most plugins and themes have similar functionality. I downloaded the demo Estatik plugin and noticed that it does have that functionality as well.

In your if statement, you're actually outputting the year field there, and it's not returning a truthy value, so it stops there (otherwise it would show 1994Year Built: 1994).

The returning function is es_get_the_property_field( $field, $post_id = 0 );

So, coupling that with a little bit of cleanup (utilizing the before/after arguments of es_the_property_field, you would end up with something like this:

<?php if( es_get_the_property_field('year-built1594411179f5f08c8ab6ff14') ){
    es_the_property_field('year-built1594411179f5f08c8ab6ff14', '<p>Year built: ', '</p>' );
} ?>

HOWEVER:

Here's the whole markup for the es_the_property_field() function:

/**
 * Render property field.
 *
 * @param $field
 * @param string $before
 * @param string $after
 */
function es_the_property_field( $field, $before = '', $after = '' ) {
    $result = es_get_the_property_field( $field );

    echo ! empty( $result ) ? $before . $result . $after : null;
}

This means you could actually drop your if statement altogether, because that function checks to see if it's empty for you. So you could simplify it even further to just:

<?php es_the_property_field( 'year-built1594411179f5f08c8ab6ff14', '<p>Year Built: ', '</p>' ); ?>

Note: I don't have any personal experience with this plugin, this is all just based on what I found in the estatik/functions.php file.
