(First posting, so please be merciful if I’m off on some of the etiquette, markup, etc. :))

Server-side:

iframe-contents.php:

<?PHP

if($_POST['test-post-parameter'] == 'test-post-value'){
echo 'test-post-parameter successfully detected as "test-post-value".';
} else {
echo 'test-post-parameter either absent or of a different value than "test-post-value". :(';
}
?>

OK, so lets say i request iframe-contents using

bash$ wget --post-data='test-post-parameter=test-post-value' -O - http://example.com/iframe-contents.php

The result would be:

test-post-parameter successfully detected as "test-post-value".

If, however, I requested it using

`bash$ wget -O - http://example.com/iframe-contents.php`

I would end up getting:

test-post-parameter either absent or of a different value than "test-post-value

Now – lets say I have another file on the server, called index.html:

<html><head><title>PAGE_TITLE</title></head>
<body>
<iframe width="100%" height="100%" src="iframe-contents.php" />
</body>

If I tried typing http://example.com/index.html into my browser, I would get PAGE_TITlE in my titlebar, with test-post-parameter either absent or of a different value than "test-post-value". :( in the body.

My question is this: How can I modify the iframe element so that I get?

test-post-parameter successfully detected as "test-post-value".

    You cannot. You can do it by using GET.

    With POST:
    Maybe only if you make a temporary .php page, that has a form with that post value, and a javascript script that automatically post the form and redirects you to the iframe-contents.php

    Something like this:

    temp-iframe.php

    <html><head>
</head>
<body onLoad="document.forms.myForm.submit()">
<form name="myForm" id="myForm" method="POST" action="iframe-contents.php">
<input type="hidden" name="test-post-parameter" value="test-post-value">
</form>
</body>
</html>

    And in the iframe src you add the: temp-ifram.php

    Hope it helps.
