Hey!
i'm just starting with PHP's DOM-XML and need a little help please.
Basically, first i am trying to see if a input like a textbox has a 'VALUE='
associated with it, if yes, i leave it be, if no, i add a default value.
This *is working* as can be seen by the attached code below.
But a bit confused as to how to do the same for a textarea as textarea's do not
have a 'VALUE=' attribute.
Heres my code:
$website_data = file_get_contents('dom_test.html');//load the website data,
$dom = new DomDocument; //make a new DOM container in PHP
$dom->loadHTML($website_data); //load all the fetched data into the DOM
container
$inputs = $dom->getElementsByTagName('input'); // Find Sections
foreach ($inputs as $input) { //*** this block has the guts of the
functionality ***
if(!$input->getAttribute("value") || $input->getAttribute("value")=="")
{
$input->setAttribute("value", "RRRRRRR");
}
}
// ***** now we come to the textarea bit that is not working *****
$inputs2 = $dom->getElementsByTagName('textarea'); // Find textareas
foreach ($inputs2 as $input2) {
if(!$input2->firstChild.nodeValue=="") {
$input2->firstChild.nodeValue=="it works!";
}
}
echo $dom->saveHTML();
?>
+++++++++++++++++++++++++++++++
// I have even tried this instead of the above:
foreach ($inputs2 as $input2) {
if(!$input2->getAttribute("defaultValue")=="") {
$input2->setAttribute("defaultValue","it works!");
}
}
but no joy.
I'm betting its pretty simple but i dont have a "DOM chart" for php, the only
ones i have been able to find via google are for javascript like this one:
http://www.hscripts.com/tutorials/javascript/dom/textarea-events.php
and that chart does not help much. Does anyone have a PHP DOM chart or a
resource that i can use to get started using this?
Thanks in advance!
