PHP - Display News And Comments

Got this script he
http://www.codewalkers.com/c/a/Database-Articles/PHPMySQL-News-with-Comments/6/

Everything works, and I mean EVERYTHING. The problem is, when the form gets submitted, the database isn't being queried/updated/whatever. It worked at first, but after I started customizing/modifying it, it quit working.

Here's my modified script:
Code: [Select]

Can anyone tell me where this script is going wrong? I've literally tried EVERYTHING. I even went back to the original script and compared every single character to mine, but NO luck.

PLEASE HELP!

I have 11 news then i want to display like

first column need only one news

second column need 5 news

third column need the rest of 5 news

I tried this but no luck, it shows first column and second column and the rest outside column

 

                    $rows = array(
                        'Title1',

                    $total_rows = count($rows);
                    $total_cols  = $total_rows - 1;// remove first one for the first column
                    $left_column = ceil($total_cols / 2);
                    $right_column = $total_cols - $left_column;

                    $i = 0;
                    foreach ($rows as $row) {
                        $i++;
                        if ($i == 1) {

I have a problem with the "comments count" in the toggle link in my blog: www.albertosotophotography.com I have this script for show/hide comments in main page:

<script type= "text/javascript">
// Show/Hide Comments
jQuery(document).ready(function() {

// Get #comments div
var uniqueAppend = 1;
var tempName = 'comments';
while(jQuery("#comments").length > 0 ){
jQuery("#comments").attr('id',tempName + uniqueAppend++).addClass('commentContainer')
}
var commentsDiv = jQuery('.commentContainer');

// Only do this work if that div isn't empty
if (commentsDiv.length) {

// Hide #comments div by default
jQuery(commentsDiv).hide();

// Append a link to show/hide
jQuery('<a/>')
.attr('class', 'toggle-comments')
.attr('href', '#')
.html('Notes')
.insertAfter(commentsDiv);

// Encase button in .toggle-comments-container div
jQuery('.toggle-comments').wrap(jQuery('<div/>', {
class: 'toggle-comments-container'
}))

// When show/hide is clicked
jQuery('.toggle-comments').on('click', function(e) {
e.preventDefault();


// Show/hide the div using jQuery's toggle()

var commentContainer = jQuery(this).parent('.toggle-comments-container').prev('.commentContainer');

jQuery(commentContainer).slideToggle('slow', function() {

// change the text of the anchor
var anchor = jQuery(commentContainer).siblings('.toggle-comments-container').children('.toggle-comments');
var anchorText = anchor.text() == 'Notes' ? 'Hide' : 'Notes';
jQuery(anchor).html(anchorText);

});
});

} // End of commentsDiv.length

}); // End of Show/Hide Comments
</script>

I use:

.html('<?php comments_number( '0 notes', '1 note', '% notes' ); ?>')

for name the "comments toggle link" with the count of comments for each single post. The problem is that all posts shows the same count: the comments presents in the first post. Someone can help me? Alberto

Hello im trying to make a comment feature by having a link under my pictures kommentar.php?link=1
Then use the link=1 to see what comments that should be taken from the database. The comments have a linkid
like this

Linkid:      Text:
1               a comment on first picture
1               another comment on first picture
2               a comment on second picture
2               another comment on second picture

But i can't get my php to echo all the comments with the linkid of for example 1 without having to get them all separately.

This is my script:

<?php
ob_start();
$host="localhost";
$username="****";
$password="******";
$db_name="db"; 
$tbl_name="comment"; 

mysql_connect($host, $username, $password)or die("cannot connect"); 
mysql_select_db("$db_name")or die("cannot select DB");

$linkid=filter_input(INPUT_GET,'link');

$sql="SELECT * FROM $tbl_name WHERE linkid='$linkid'";
$result=mysql_query($sql);
$grejs=null;
while(mysql_fetch_row($result)){
$grejs.="$row[0]";
}
echo $grejs;
ob_end_flush();
?>

Hello!

I'm trying to dive into Dreamweaver's code so that I can better understand what the heck it's doing in order to modify it to my specific needs.  My PHP book is great, but it just seems like Dreamweaver's code is much more complicated than how I'd write it based on what I've read about PHP (Disclaimer: been with PHP for a week).  It would be incredibly helpful if someone could write comments for each of the lines in terms of what it's doing (the more specific the better).  I appreciate that this is a bit of a tedious question to ask, but it would be really appreciated.

Thank you.
