I added some new improvements to the “Insert Script” WordPress plug-in. You can now declare a JSON string and it will parse it out as $json_vals_arr, an array that gets passed directly to your external PHP script.
You can also declare “strings” instead of “vals” as a GET URL string like: “strings=’variable1=value1&variable2=value2&etc=andSoOn'”.
To download the most recent version, type in “Insert Script” and select the plug-in author “Aaron Belchamber”. To learn more, visit the official Insert Script WordPress Plug-in Page. This is a simple and clean way for WordPress PHP developers looking to integrate external scripts and content within a WordPress page, post, or widget.
