存储值并检查值是否为空

Question

Is there a way I can check if the value of

<?php the_field('max_working_height')?> 

is empty or store the value that will be displayed when I use acnd check if that is empty or not. If the value is not empty then I have to make it execute a set of html code and php code like this

    <tr style="height: 25px; margin-left: 10px;">
<td style="margin-left: 10px;"><b>Max
  <?php the_field('max._outreach'); ?></td> 
</tr>

Please help.

Answer 1

<?php
$maxWorkingHeight = the_field('max_working_height');

if (false == $maxWorkingHeight) {
    // print your html/php
} else {
    // you can print $maxWorkingHeight here if you need it
}

That assumes that your function returns a falsy value if the field isn't set ( null , false , 0 , or an empty string are all examples of falsy values in PHP).

If, as it appears, you are using the ACF plugin, then the_field() echos out the value of the field. If you want to capture the value of the field, use get_field() . Check out the docs here .
