How to display images when a link is clicked using JQuery, PHP & MySQL?
Lets say a member is displaying 10 images by default but a link will display the rest of the users images by having them slide down when a user clicks a link.
So my question basically is I want to be able to display all the users images buy having them slide down when a user clicks on a link <a>
. How would I be able to tackle this problem 开发者_StackOverflow中文版using JQuery, PHP & MySQL?
check this plugin, it's not what you asked, but it's (IMO) a better solution

BTW : PHP and MySQL are arbitrary in that question since it depends how your images are stored on the server
This will take care of it.
<script>
$(document).ready(function() {
$(".more").toggle(
function() {
$(this).text('less');
$(this).parent().children(".bottom_images").slideDown("fast");
return false;
},
function() {
$(this).text('more');
$(this).parent().children(".bottom_images").slideUp("fast");
return false;
});
});
</script>
<style>
.bottom_images {
display: none;
}
</style>
<div class="container">
<div class="top_images">
<?php
//num images to originally display
$num_show=10;
//current position
$i=1;
//some code to get user images
//from database etc
foreach($images as $image_url) {
if($i==10) {
echo '</div><div class="bottom_images">';
}
echo '<img src="'.$image_url.'" />';
$i++;
}
?>
</div>
<a href="#" class="more">more</a>
</div>
Obviously there is some pseudo code for retrieving the user images as there are a number of ways you could get the images eg. from database (as a blob or text url), scanning the file system, user input etc etc. Also I have made it so you can add multiple containers (multiple users) into the one page.
It depends on various aspects how do you want to do it.
- You can use LazyLoading as provided by Yanick Rochon
- You can preload all the images and simply show the hidden ones when
clicked. - You can also load additional images using AJAX
- You can load the visible images first and after all they're loaded - preload invisible images so to show them instantly after clicking a link
Describe your problem a little bit deeper.
