Rats. Looks like you can't encapsulate DOM objects in your own classes.
I tried this and the browser 'view source' shows a completely empty
document.
<?php
$x = new MyDom();
$x->createScriptElement('howdy.js');
class MyDom
{
function MyDom()
{
$dom = new DOMDocument('1.0', 'iso-8859-1');
return $this;
}
function createScriptElement($inScriptPath)
{
$script = $this->dom->createElement('script','');
$script->setAttribute('language', 'javascript');
$script->setAttribute('src', 'howdy.js');
$this->dom->appendChild($script);
echo $this->dom->saveXML();
}
}
?>
Made a few changes to it as follows and it works perfectly here (PHP
5.0.5, Gentoo Linux):
<?php
$x = new MyDom();
$x->createScriptElement('howdy.js');
print($x->saveXML());
class MyDom {
private $dom;
/* __construct() = PHP5 constructor */
function __construct() {
$this->dom = new DOMDocument('1.0', 'iso-8859-1');
/* No need to return $this from a constructor */
}
function createScriptElement($scriptPath) {
$script = $this->dom->createElement('script', '');
$script->setAttribute('type', 'text/javascript');
$script->setAttribute('src', $scriptPath);
$this->dom->appendChild($script);
/*
Doesn't make sense for a createScriptElement()
method to also print out the XML, so I made a
separate method and called that from the
mainline code.
*/
}
function saveXML() {
return $this->dom->saveXML();
}
}
?>
