自定义php文件中的PHP do_shortcode

Question

I've created a little bit of js that passes three variables to my php script loadtable.php. This php file is stored in my child theme folder and its contents are as follows:

<?php

$d = Date('Y-m-d', strtotime($_GET['d']));
$c = $_GET['c'];
$b = $_GET['b'];

$shortcode = "[wpdatatable id=3 var1=".$b." var2=".$d." var3=".$c."]";
echo do_shortcode('$shortcode');

The js part on the page:

window.onload = selectChart;

function selectChart () {
  var date = document.getElementById("date");
  var country = document.getElementById("country");
  var label = document.getElementById("label");
  var xDate = date.value.toString();
  var xCountry = country.value.toString();
  var xLabel = label.value.toString();

if (window.XMLHttpRequest) {
            // code for IE7+, Firefox, Chrome, Opera, Safari
            xmlhttp = new XMLHttpRequest();
        } else {
            // code for IE6, IE5
            xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");
        }
        xmlhttp.onreadystatechange = function() {
            if (this.readyState == 4 && this.status == 200) {
                 document.getElementById("chartTable").innerHTML = this.responseText;
            }
        };
        xmlhttp.open('GET','/wp-content/themes/Avada-Child-Theme/loadtable.php?d='+xDate+'&c='+xCountry+'&b='+xLabel,true);
        xmlhttp.send();
    }

I just can't get the do_shortcode php script to render the table when the page loads or when selectChart() is called. Do any of you know what my solution is? Thanks in advance.

Answer 1

I think that you have to import the wp-load.php file. require_once("../../../wp-load.php" );

And then echo do_shortcode('$shortcode'); I am not sure the code is working. echo do_shortcode("$shortcode");

Answer 2

You should to use wordpress autoload first to be sure every necessary wordpress files like wp-config.php is loaded to your script and then use the wordpress function do_shortcode().

So your loadtable.php script should be something like this:

<?php

require_once("../../../wp-load.php"); // wordpress autoloader

$d = Date('Y-m-d', strtotime($_GET['d']));
$c = $_GET['c'];
$b = $_GET['b'];

$shortcode = "[wpdatatable id=3 var1=".$b." var2=".$d." var3=".$c."]";
echo do_shortcode('$shortcode');

It works only when your script is in the root of your child theme folder. So if your script is located somewhere else, your path (../../../wp-load.php) should be changed.
