My webpage allows users to select items from a dropdown list and has a table. Javascript prints out each dropdown-list-item (plus extra info that javascript pulls from the XML file) in a new table row that javascript creates.

I want to be able to write the table information to disk.
If I was using Javascript, I would use document.getElementByID(“table”) to parse through the nodes and put that info into variables that I could write. However, most documentation I find says Javascript is not used for writing to disk. So, I think I should use php.

What is the php equivalent of Javascript’s ‘document’ object?
In Javascript I don’t need to define any new objects to use it, I can use ‘document’ anytime.
I think in php I have to use new DOMDocument. and then load the html.

Most of the php examples show loadHTML(string) and loadHTMLFile();
I don’t want to load HTML from a string that I write inside the tags.
And I don’t want to load HTML from the .htm file because that’s the original file and Javascript has changed the user’s file based on their selections from the dropdown menu.

I want to access the elements of the current document using php.
So, how does php refer to the current document?

The page I’m working on is http://music.collwyncraig.info/hajimama/setlist.htm

    I think your thoughts about the architecture are wrong. There is a way how the programming languages interact with each other.

    • php is a preprocessor and generates – what ever u want – usually html, containing javascript, css, and whatever…
    • javascript is a dynamic language that interacts in the generated html documents or calls by ajax other services that deliver html, javascript, css or whatever is needed
    • and html – that is document object that is displayed and can be modified during the runtime by javascript an styled by css, etc…

    So when u call in your documents javascript functions – the basic php has already done its job.

    Instead of printing all generated contents from php directly to the screen, you can store it first in a var.

    For example:

    $myContent = "<html><head>...</head><body><h1>Whatever...</h1></body>";

    so with that you can do the following to print it on the screen:

    print "myContent";  // and it is shown on the screen

    or

    $myFile = "testFile.html";
$fh = fopen($myFile, 'w') or die("can't open file");
$myContent = "<html><head>...</head><body><h1>Whatever...</h1></body>";
fwrite($fh, $myContent);
$myContent = "Whatever2";
fwrite($fh, $myContent);
fclose($fh);

    So the contents of your file would be:

    <html><head>...</head><body><h1>Whatever...</h1></body>Whatever2

    This generated document can then be called by loadHTML or used in which way you
    want.

    This just as a hint into which direction you can think – there are quite multiple ways of solution – so without knowing more about what u really want – it is quite not easy to mention a proper solution.
