Introduction

Highcharts is a powerful JavaScript library used to create interactive charts and graphs. It is widely used in web applications to visualize data in an easy-to-understand format. However, when setting Highcharts head tag, it can be difficult to get PHP variables in the JS script. This article will discuss how to solve this issue and provide a solution.

Solution

The best way to get PHP variables into a JavaScript script is to use AJAX. You can use the jQuery library to make an AJAX call to a PHP script that will return the data you need. Then, you can use the data returned from the AJAX call to set the options for your Highcharts chart.

Here is an example of how to do this:

// Make an AJAX call to a PHP script that will return the data you need
$.ajax({
url: ‘get_data.php’,
type: ‘GET’,
dataType: ‘json’,
success: function(data) {
// Set the options for your Highcharts chart
var options = {
chart: {
type: ‘bar’
},
title: {
text: ‘My Chart’
},
xAxis: {
categories: data.categories
},
series: [{
name: ‘Data’,
data: data.data
}]
};
// Create the chart
Highcharts.chart(‘container’, options);
}
});

Solved: Can’t Get PHP Variables in the JS Script When Setting Highcharts Head Tag

If you’re having trouble getting PHP variables to work in the JavaScript script when setting the Highcharts head tag, you’re not alone. Many developers have encountered this issue and have been unable to find a solution. Fortunately, there is a way to get around this problem and make sure your PHP variables are properly set in the JavaScript script.

The key to solving this issue is to use the json_encode() function in PHP. This function will take any data type and convert it into a JSON string, which can then be used in the JavaScript script. To use this function, simply pass the PHP variable into the function and it will return a JSON string.

Once you have the JSON string, you can then use it in the JavaScript script. For example, if you have a PHP variable called $data, you can use the following code to set the Highcharts head tag:

Highcharts.setOptions({
    chart: {
        type: 'line',
        data: 
    }
});

By using the json_encode() function, you can ensure that your PHP variables are properly set in the JavaScript script. This will allow you to use the Highcharts head tag without any issues.
