DebugKit CakePHP 3.x ReferenceError：未定义__debug_kit_id

Question

I recently upgraded php from 5.6 to 7 and I think it broke CakePHP's DebugKit. On every page I navigate to within my app, the debug_kit javascript file produces an error, specifically when setting the currentRequest. The error is:

At first I didn't install sqlite, so I thought that was the issue, but after installing the sqlite, mbstring, and intl extensions the error is still there. I can't seem to find an answer anywhere, most of the problems people encounter with debugkit seem to be solved by installing sqlite.

The code snippet from the debug_kit.js file:

$(document).ready(function() {
    toolbar = new Toolbar({
    button: $('#toolbar'),
    content: $('#panel-content-container'),
    panelButtons: $('.panel'),
    panelClose: $('#panel-close'),
    keyboardScope : $(document),
    currentRequest: __debug_kit_id,
    originalRequest: __debug_kit_id,
    baseUrl: __debug_kit_base_url
});

toolbar.initialize();

Thanks everyone!

Answer 1

This not appear to be a PHP error, but rather a Javascript one because the variable __debug_kit_id is not defined anywhere in your Javascript code. Define it to be something like

var __debug_kit_id = 0;

or whatever value it should have and that will solve your error.

I was able to solve my own problem by removing all remaining php5 packages. I followed bento's answer from this askubuntu question: https://askubuntu.com/questions/59886/how-to-compelety-remove-php and going one by one through the old php5 packages (leaving php7 packages intact). Thanks all
