Debugging & Tracy

Debugger::enable();

Catching bugs early

In the case of syntax or logic errors, Tracy would show a screen such as the one below. For this example we made a mistake not writing the closing ) parenthesis for the the_content() WordPress function.

<div class="content">
  {the_content(}
</div>

Error screen thrown by Tracy:

Logging

When it comes to logging, we have two options with Tracy.

• Logging in-place – dump() function
• Logging to the Tracy debug bar – bdump() function

We’ll use the same simple example for both cases.

Let’s say we have this array that we want to log (It might be coming from the database).

{var $test_arr = [
  [
    'id' => 1,
    'name' => 'Jane Doe'
  ],
  [
    'id' => 2,
    'name' => 'John Doe'
  ]
]}

To log this array in place, we would use Tracy’s dump() function like so.

{do dump($test_arr)}

This would be the result of calling the dump() function.

---

To log to Tracy’s debug bar, we would call the bdump() function.

{do bdump($test_arr)}

Now, the logged array would be shown inside Tracy’s debug bar, like so.
