The Effect I'm Trying to Achieve...

nick1 · April 27, 2006

I'm not sure how to describe the effect I'm trying to achieve, so I'll point out a website that has implemented what I'd like to do:

[a href=\"http://isohunt.com/torrents.php?ihq=nature&ext=&op=and\" target=\"_blank\"]http://isohunt.com/torrents.php?ihq=nature&ext=&op=and[/a]

Notice that a 'drop down' menu appears when a title is clicked on.
How is this done? Can PHP accomplish this neat feature?
On my website I have a blog and I want readers to have the option of leaving a comment about a blog entry.
But I don't want all the comments displayed at once. At first, I only want to display the number of comments that exist for a specific blog entry. Then make that number a hyperlink that drops down the comments for that specific blog entry. Make sense?

So basically:

------------------------
| Blog entry here............|
| blah blah blah blah blah |
| blah blah blah blah blah |
| blah blah blah blah blah |
| blah blah blah blah blah |
| blah blah blah blah blah |
------------------------

There are 5 comments available. (clicking the #5 would display the comments)

--------------------------
|comment 1: blah blah blah |
--------------------------

--------------------------
|comment 2: blah blah blah |
--------------------------

--------------------------
|comment 3: blah blah blah |
--------------------------

--------------------------
|comment 4: blah blah blah |
--------------------------

--------------------------
|comment 5: blah blah blah |
--------------------------

Close Comments (this feature would make the comments disappear again)

Any help would be greatly appreciated! Thank you for your time,

*Nick*

Looks more like JavaScript, remember - PHP is a server side language.

You don't need php to do this, you need javascript/css

1. create a div that contains all your comments, give it an id or a class that you refer to in your css file

<div id='comment'>
comments go here
</div>

2. in the css, set 'display: none;' for the div that contain comments
3. create a button on your page
4. add the onclick event (javascript) to the button

<input type='button' value='show comments' onclick="document.getElementById('comment').style.display=block;">

this is all from the top of my head, I usually keep javascript language reference nearby. If you want to do some other things or just to keep things readable in your code, you could create a function that doest the same.

<input type='button' value='show comments' onclick="showcomments()">

<script type='javascript'>
var comment = document.getElementById('comment').style;
comment.display = 'block';
</script>

Warning: this will NOT create the slider effect, you need something like on [a href=\"http://script.aculo.us\" target=\"_blank\"]http://script.aculo.us[/a] for that, don't ask me questions about it, cos I just know it exists, never used it

Greetings,

Thank you for trying to help me out with this small project. I very much appreciate your ideas and time.
Unfortunately the only thing I see when I try to execute this code is the button. I'm not sure why it isn't working.

Here is my index.html page:

[code]<html>
<head>
<title></title>
<link rel="stylesheet" href="index.css" type="text/css" media="screen" />
</head>

<body>

    <div id='comment'>
        comments go here
    </div>

    <input type='button' value='show comments' onclick="document.getElementById('comment').style.display=block;">

</body>
</html>[/code]

And here is my index.css page:

[code]#comment {
  display: none;
}[/code]

Sorry, I don't know Java at all. I tried researching some things on Google, however, that lead to lots of frustration trying to troubleshoot something I don't understand. What do you think needs adjusting in this code?

Thank you for your continued help,

*Nick*

you need to ask this question on javascript forum this is php forum not trying to be rude but you're more likely to find a good answer there.

I'll move this to our JavaScript forum. Please be aware, Java and JavaScript are two very different languages!

Hi there,

Try this code example,,
html/javascript part is about:
[code]
<html>
<head>
<link rel="stylesheet" href="index.css" type="text/css" media="screen" />
</head>
<body>

<script>
function ShowComments(comment_id,text_id,nb)
{
var tochange="<span class=\"comments\" onclick=\"HideComments('"+comment_id+"','"+text_id+"',"+nb+");\"";
tochange=tochange+" style=\"background-color:#ECECD9;\"";
tochange=tochange+" onmouseover=\"\"";
tochange=tochange+" onmouseout=\"\">";
tochange=tochange+"see the comment "+nb+"</span>";
document.getElementById(comment_id).innerHTML=tochange;
document.getElementById(text_id).style.display="block";
}

function HideComments(comment_id,text_id,nb)
{
var tochange="<span class=\"comments\" onclick=\"ShowComments('"+comment_id+"','"+text_id+"',"+nb+");\"";
tochange=tochange+" style=\"background-color:#CAD9EA;\"";
tochange=tochange+" onmouseover=\"this.style.backgroundColor='#ECECD9';\"";
tochange=tochange+" onmouseout=\"this.style.backgroundColor='#CAD9EA';\">";
tochange=tochange+"see the comment "+nb+"</span>";
document.getElementById(comment_id).innerHTML=tochange;
document.getElementById(text_id).style.display="none";
}
</script>

<div id="comment1">
<span class="comments" onmouseover="this.style.backgroundColor='#ECECD9';" onmouseout="this.style.backgroundColor='#CAD9EA';" onclick="ShowComments('comment1','text1',1);" >see the comment 1</span>
</div>
<div id="text1" class="text" style="display:none;">
<table border=1 align=center width="700px">
<tr><td style="background-color:#CAD9EA;">
This is my first comment,...<br>hoping it's a nice one,...
</td>
</tr>
</table>
</div>
<div id="comment2">
<span class="comments" onmouseover="this.style.backgroundColor='#ECECD9';" onmouseout="this.style.backgroundColor='#CAD9EA';" onclick="ShowComments('comment2','text2',2);" >see the comment 2</span>
</div>
<div id="text2" class="text" style="display:none;">
<table border=1 align=center width="700px">
<tr><td style="background-color:#CAD9EA;">
& this is my second comment,,  :)
</td>
</tr>
</table>
</div>
</body>
</html>
[/code]
& index.css file:
[code]
.comments {
    cursor:pointer;
    background-color:#CAD9EA;
    border: 1px solid gray;
    width:800px;
    padding:0.1em;
}

.text {
    background-color:#ECECD9;
    border: 1px solid gray;
    border-top:none;
    width:800px;
    padding:0.1em;
}
[/code]
it gives also the slider effect using onmouseout/onmouseover properties,

Hoping it helps,,
