Simple CMS function like CushyCMS

BenGilbert

I'm exploring simple cms options for small content websites, where a client could possibly want to just update text in certain area of a page. While I like CushyCMS 's overall idea, I do not like them having my information and the cost associated with it.

My questions fall under, how does their system work exactly. How do they scan a webpage for certain css classes and retrieve that specific selection from the page.

For those not familiar with CushyCMS, it is a host simple cms service where you signup, and you place a CSS Class in your code ex. <p class="editcms"> text / code here </p> and it will find all instances of this class and then display the elements contained within the class in editable text areas, etc where a client can then edit and save the file.

I can't figure out how to scan / read the webpage file and select the specific content. Any advice / links to advice would be greatly appreciated. It is an interesting concept I just want to implement on a small scale.

Thanks for advice and help in advance.

PHP's [man]DOM[/man] extension could do that, if I understand correctly.

So this is where I am currently. I know it is ugly, but I am gathering my thoughts to get it to work.

<?php 

$content = file_get_contents("http://localhost/test/openme.php");

$start = '<p class="edit">';
$end = '</p>';

$pos1 = strpos($content, $start );
$pos2 = strpos($content, $end , $pos1); 

$length = $pos2-$pos1;
$result = substr($content, $pos1, $length ); 

echo $result; 

?>

However this only returns the first instance of the desired class. I would need to scan the contents until all instances were displayed. I am having trouble writing a while or for statement to do this. I do not know how to have php start it's search again after the first time through at the location after the first instance of $end in the $contents.

How can I record the location of the $end, and then have the while statement continue its scan at that point?

Thanks Again

If you want to go that route, you probably want to use [man]preg_match_all/man with the "Ungreedy" modifier.

why not install a 'real' cms ?
