Question by phall257:
Can someone help with my php problem?
Hi I need help with my php script. This is a basic site that creates a portfolio page of photographs. On the top it has the massive picture, and on the bottom there are thumbnails that update the photo on top when you hover with your mouse. My problems are that (a) I need the thumbnails to wrap after 5 images (start a new line of thumbnails) and (b) I would love it if when you CLICK the thumbnail, it “locks” that picture in place (so when you move your mouse over another photo it will not change – but I do still want the hover feature until they click, not sure if it is possible.) Here is my code so far:

< ?php

$ thumbnail_height = 60;
$ image_height = 400;

function format_portfolio ($ dirname, $ filenames)
{
global $ thumbnail_height;
global $ image_height;

$ str .= "

“;
}
$ str .= “

“; // the thumbnail box
$ str .= “”; // the overall portfolio
return $ str;
}

function get_portfolio_html ($ dirname)
{
$ count = 0;
$ filenames = array();
if ($ handle = opendir(“images/$ dirname”)) {
while (false !== ($ file = readdir($ handle))) {
if ($ file == ‘.’)
continue;
if ($ file == ‘..’)
continue;
$ filenames[$ count] = $ file;
$ count++;
}
closedir($ handle);
}

//$ str .= “found $ count items in ‘$ dirname’
“;
$ str .= format_portfolio ($ dirname, $ filenames);
return $ str;
}

function display_portfolio ($ dirname)
{
$ str = get_portfolio_html ($ dirname);
echo $ str;
}

?>
Any help would be great. I do not really care about (b) – my first need is much more urgent. Thanks in advance!!
