I want to pass an array of data to my script mygaloochart_script located in the chart.js file.

Here's what I tried:

//I'm no using $atts directly because of reasons
$dataToBePassed = array (
                'chart' => $atts['chart'],
                'element' => $atts['element'],
                'elementtype' => $atts['elementtype'],
                'title' => $atts['title']
);

function pw_load_scripts() {
    wp_enqueue_script('googlechart', 'https://www.gstatic.com/charts/loader.js');
    wp_enqueue_script('mygaloochart_script', plugins_url('chart.js', __FILE__), array('googlechart'));
    wp_localize_script('mygaloochart_script', 'php_vars', $datatoBePassed);
}

 add_action('wp_enqueue_scripts', 'pw_load_scripts');

The first line of chart.js is console.log(php_vars.chart);, however nothing appears in the console.

What am I doing wrong?

  • wp_enqueue_scripts should be the action name, I guess wp_enqueue_script is the mistake you have done while asking a question. – bravokeyl Jun 20 '16 at 12:55
  • Why are you enqueue-ing googlechart outside of the wp_enqueue_scripts action hook? – bravokeyl Jun 20 '16 at 12:56
  • Edited with your remarks, but still the same issue. @bravokeyl I think t's being enqueued in the wp_enqueue_script('mygaloochart_script', plugins_url('chart.js', __FILE__), array('googlechart')); – user97067 Jun 20 '16 at 13:02
  • my guess is chart.js is not being enqueued. On the other hand $dataToBePassed is outside the scope of the function , it gives you null. – bravokeyl Jun 20 '16 at 13:21
  • What do you mean it's not enqueued? How should I enqueue it? – user97067 Jun 20 '16 at 13:22

How does your function pw_load_scripts() know about the existence of $dataToBePassed? Is the variable global? Looking at the code you've got, I'm guessing that, as far as wp_localize_script() is concerned, $dataToBePassed is a local variable, and it's probably null.

    I solved it. The issue was... $datatoBePassed should be $dataToBePassed – user97067 Jun 20 '16 at 14:59
