Php和MySQL：根据用户点击的链接从数据库中检索数据

Question

I've put a set of small images to function as links (around 50 more or less) on a page. In that same page I have a content place holder to display data from the database, and I have a table saved in phpmyadmin that has a set of fields filled with data.

What I want is when the user clicks on a certain image link, the data related to that image gets retrieved into the site. So I want the data to be retrieved to match the image clicked.

I know how to retrieve data from a database using the binding pannel in dreamweaver, and I know this has to do with filtering the data retrieved but I don't know how to do it.. How can I make this process work?

If it helps I'm also using Jquery CSS and javascript in this project.

The project looks like this:

HTML code:

it doesnt show I took a screenshot of it:

jQuery code:

$(document).ready(function() { // begin Ready

//...................................................
// When the form changes
$('#mapForm').change(function() {

    var selectedContinent = $('#mapForm option:selected').val();
    if (selectedContinent == 'ALL'){
        $('a.dot').slideDown(1000);
    }else{
        $('a.dot[continent = "'+selectedContinent+'"]').slideDown(1000);
        $('a.dot[continent != "'+selectedContinent+'"]').slideUp(1000);
    }

});

//...................................................
// When a dot is clicked
$('a.dot').click(function(){

    $('a.dot').removeClass('selected');
    $(this).addClass('selected');

    var city = '.city_detail#' + $(this).attr('city');
    var htmlCode = $(city).html();

    $('.detail_container').fadeOut(500, function(){
        $('.detail_container .city_detail').html(htmlCode);
        $('.detail_container').fadeIn(500);
    });

});

// end Ready });

You need to create a PHP script which takes a REQUEST variable parameter depending on the image that has been clicked, and which returns the data for that image.

You can then make a call to that PHP script via AJAX and populate whichever area of the page you want to with the data retrieved.
