<?php

// The function strlen() returns the interger value of the string length within the parentheses
// We can string multiple together with math operators for equations

// PHP enabled in template
// Parsing Stage: Output

// Simple conditional here
// We group the strlen values in parentheses to get their value
// and compare to the following integer (10 in the example)

// Basic example
if ((strlen("{custom_field_1}") + strlen("{custom_field_2}")) > 10)
{
   // whatever your code requires
}


// Alternate syntax
if ((strlen("{custom_field_1}") + strlen("{custom_field_2}")) > 10) :

   // whatever your code requires

endif;

?>



<p>Here's how I would use it in a template:</p>

<?php if ((strlen("{custom_field_1}") + strlen("{custom_field_2}")) > 100) : ?>   

This shows up because the combined length of {custom_field_1} and {custom_field_2} is greater than 100.
