Im currently creating my own plugin to window.print a post on my WordPress website.
But it seems that i cannot acces the function thru the onclick. If i put the window.print in the button itself it works, but that is not how it has to work for me.
// Only do this when a single post is displayed
if ( is_single() ) {
// Message you want to display after the post
$content .= '<button type="Submit" value="Print_PDF" onclick="GetPDF()"> Print PDF </button>';
}
// Return the content
return $content;
}```
But whenever i click the button i get an error that says that it does not acces this function:
``` function GetPDF() {
window.print();
}```
It is in the same file.

The HTML element’s onclick attribute looks for a javascript function, it cannot run a PHP function.
