hmmm, that is the Javascript part. Perhaps I will expand on this..
* I have a very simple HTML page, with a FORM, with an INPUT TEXT
* there is a button that activates some javascript
* the javascript causes this to happen
// Create new JS element
var jsel = document.createElement('SCRIPT');
jsel.type = 'text/javascript';
jsel.src = url;
// Append JS element (therefore executing the the PHP call)
document.body.appendChild (jsel);
url points to a PHP file! the appendChild has the effect of causing the
script to be executed. Apparently the broswer thinks it is Javascript,
so the javascript in it runs, but the suffix is .php, so the server sees
it , and the PHP runs. Really, it works.
The reason I did this is to run a MySQL query from PHP, based on a
dynamic input value. But here is where I got stuck.. I can read the DOM
element in javascript. I need the value in the PHP block. I thouht I
would just try the DOM calls in PHP, but they read an HTML file, or else
read 'html', but I don't know how to point the php call at the _workin_
page; or alternatively, read the element in JS and pass it in SOMEHOW to
the pHP code block.
Questions and clarifications gladly made, I really want to make this
work. thanks in advance
