link displayed image to php function?

[fukumdaryl]

is there a way to link an image displayed to a function? here's my code:

function showThumbs(){
include("header.php");
opentable();
echo "<table>";
$result = mysql_query("SELECT * FROM nuke_Submit_Art WHERE category = 'painting'");
if ($result){
if (mysql_num_rows($result) > 0){
while ($row = mysql_fetch_assoc($result)){
echo "<tr><td><img src=\"{$row['thumbPath']}\"></td>\n";
echo "<td>{$row['imageID']}</td></tr>\n";
}
}
}
echo "</table>";
closetable();
include("footer.php");
}
function showPage(){
}
switch($func) {

default:

showThumbs();

break;


case:

showPage();

break;

}
?>

I'm doing for a phpnuke module, but I don't think that should enter into it. I want so when the user clicks the thumbnail, it will bring up the showPage() function, which I haven't finished yet. Thanks.

you will need to put the showimage() function in a file, then point the link to that file. dont forget php runs on the server, so in order for any php function to run, a new request needs to made to the server.

I figured that, but my main concern is about the actual linking of a thumbnail and text to the showimage function in the original code on the page, maybe with an onclick function. ex
echo "<img src=\"muffin.jpg \" onClick=\"showImages()\"";

or something in that vein. I want to know how to link the image to the function without using a form. Thanks in advance.

How about the usual way of linking:

<a href="mylink.php?var=var" alt="link to functionpage"><img src="myimage.jpg" alt="" width="" height=""></a>

php is run on the server while onclick events are on the client, so your way of thinking wont work. no matter how you do it, in order to run your php function you'll need to make a request to the server.

-I know. Onclick is javascript. I want to know if there is some php equivilent that will link to a funtion on the same page, like when the user clicks the thumbnail, the full sized image will pop up with the description, submitter, etc.

Why not just link to a new page, which will pull all the info?
