PHP - Comment Refresh Glitch. Mutliply Comments Need Help!

The following block of code won't work.
Code: [Select]
$prob = $prob + 1;
$_SESSION['prob']=$prob;
header( 'Location: question' . $prob . '.php' );
This is just a small part of my script. I've made sure using print that $prob is 1 and is changed to 2. HOWEVER it gives me an error 404 page at question3, not question2.
I'm trying to make a quiz system.

Hi all,

Thanks for reading.

I'm running a script using jQuery that auto-refreshes a <div> on the index page from an external PHP script to get all the rows in a database and display them on the index page. The script works great - here it is as follows:

Code: [Select]
<script type="text/javascript">

$(document).ready(function() {

$("#responsecontainer").fadeOut("fast").load("getrows.php").fadeIn("slow");

var refreshId = setInterval(function() {
$("#responsecontainer").fadeOut("fast").load('getrows.php').fadeIn("slow");
}, 5000);

$.ajaxSetup({ cache: false });

});

</script>

The getrows.php script I'm working with looks like this:

Code: [Select]
<?php 

$rowsQuery = mysql_query("SELECT * FROM Happenings WHERE HappeningDate='$today'");

if (mysql_num_rows($rowsQuery) == 0) {
$happeningsToday = "There are no happenings today.";
} else {

$allHappeningsToday = 1;

while ($getHappeningsToday = mysql_fetch_array($rowsQuery)) {

$happeningName = stripslashes($getHappeningsToday['HappeningName']);
$happeningDate = $getHappeningsToday['HappeningDate'];
$happeningDescription = $getHappeningsToday['HappeningDescription'];

if ($allHappeningsToday == 1) {

$happeningsToday .= "
<div class=\"box\">
<p>".$happeningName." | ".$happeningDate." | ".$happeningDescription."
</div>";

$allHappeningsToday = 2; 

} else { 

$happeningsToday .= "
<div class=\"box\">
<p>".$happeningName." | ".$happeningDate." | ".$happeningDescription."
</div>";

$allHappeningsToday = 1; 

}

}

}

echo $happeningsToday;

?>

This script works great as well.

Currently, the auto-refresh jQuery script as you can see if getting and fading in/out all of the rows.

Off of the above getrows.php script, is there a way after I could get only the newly created rows since the last refresh and only fade those in and out while leaving the others already loaded by the auto-refresh script to not fade in/out?

Any ideas, thoughts or suggestions would be unbelievably helpful.

Thank you very much.

I have an issue with a form where people choose from several classes, and how many people they're enrolling. If they choose the first class, select the number of students and hit submit, it is supposed to carry the number of students to the 2nd page where a variable is created for it:
$qty = $_POST['participantqty'];

It works if they pick the first class and choose a number of students.
It works if they pick the first class and another, plus the number of students for each.

But if they choose any one class except the first one (and only that class), choose their number of students and submit...
This is when it doesn't carry the number forward...

It also glitches when they select two classes that don't include the first class. It carries the number of students for one, but not the other.

qty_insert and qty_total on page two are where the data dissappears. I'm assuming it has something to do with the array, but I'm in a little over my head.

On the second page, I added in print_r($myarray); and it shows the variable is passing to the second page.

page one:
Code: [Select]

<form method="post" action="register2.php">

 <? //output each row

  while ($c_row = mysql_fetch_array($result_all_events)){
$display = date("F j", strtotime($c_row['workshop_date'])) ;
$i++;
//date('d m y', strtotime($mysql_date));


    ?>
 
<input type="checkbox" name="workshop_id[]" value="<?= $c_row['workshop_id'] ?>" /> <?= $c_row['workshop_title'] ?> </td><td><?= $c_row['workshop_date'] ?></td><td><select name="participantqty[]" id="" class="">
<option value="">select</option>
  <option value="1">1</option>
  <option value="2">2</option>
  <option value="3">3</option>
  <option value="4">4</option>
  <option value="5">5</option>
  <option value="6">6</option>
  <option value="7">7</option>
  <option value="8">8</option>
  <option value="10">9</option>
  <option value="10">10</option>
</select>
$ <?= $c_row['workshop_price'] ?></td></tr><tr><td colspan=3><hr></td></tr>


  <?

  } //end while
  ?>

<input type="submit" value="Submit" class="buttontype">


and on page two where it totals things up:

Code: [Select]

why does this not refresh if i comment "Comment..." it just dies and doesnt echo anything

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.

Code: [Select]
$editFormAction = $_SERVER['PHP_SELF'];
if (isset($_SERVER['QUERY_STRING'])) {
  $editFormAction .= "?" . htmlentities($_SERVER['QUERY_STRING']);
}

if ((isset($_POST["MM_insert"])) && ($_POST["MM_insert"] == "form2")) {
  $insertSQL = sprintf("INSERT INTO users (first_name, last_name, user_type, email, school_id) VALUES (%s, %s, %s, %s, %s)",

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();
?>

Okay...

Since my last post about the website I was working on, I've figured out what I was asking.  But now, I've run into another problem...

Once I have a functional form on my website where a user inputs data and presses submit, how do I go about getting it to remain posted where directed?  So if the user types his first and last name and presses submit, how do I get their input to remain posted on the page, much like a guestbook?

I'm a newbie at this stuff, but it's a must for mine and my partner's website.  Thanks again!

PS... I have the code for the form all typed out and it works, it just displays the data with $echo rather than posting it permanantly.

Is it true that PHP Comments are hidden from end users?

And is it dangerous to put extensive comments in your code (e.g. links to developer sites, article excerpts, etc)?

I am re-factoring my website, and have found some really helpful articles that I'd like to post in my code so I don't forget what I'm doing 6 months from now, but don't want to cause any issues.  (I know this sounds wimpy, but I am a newbie?!)

Hello,

I have built a blog in php but. On each article in the blog people are able to comment.

I would now like to build a system where people can vote on the comment up/down with Ajax.

In my comments database I have a table that looks like this:

id / article_id / user_id / dateposted / comment    / voteup / votedown

I would like it to look like this:


Any ideas how I can do this? Tutorials online?

Thanks a million

I have one small question about comments.

say you have a code like this

Code: [Select]
<?php 

$lol = 1;
$rofl = 2;
$lmao = 3;
// Above are my variable's 

echo 'this does not get executed because the apostrophy in the comment acts as the start';

?>

Now if I wrote this code the apostrophe in variable acts as a quote and does not end until it meets another to end it. Why does this do that? I thought that when you start a comment that whole line gets ignored. 

Could this possible be happening because of my text editor( I use textpad )? If so could you recommend a good text editor, thanks.

Hi all,

I have another uestion. I am currently working with an XML document that has some comments in it that need to stay however it is messing up my parser that I am working on. How can I get around this issue and make the php parser ignore the comments? here is a snippet of the code I am working on.

php
Code: [Select]
//open XML file containing data for current slide

$currentslidefilepath = "slides/xml/";
$currentslidefilepath .= $slides[$currentslide];
$currentSlideXml = simplexml_load_file($currentslidefilepath); 

XML
Quote

<!-- there are some comments here -->

<Basic>
         <another>some data</another>
</Basic>

ok here is my script , for some reason , it adds the comment and all it works great , but it wont add it to the notifications table in my database
Code: [Select]
<?php include("../includes.php");
$session = $logOptions_id;
if($session)
{
$to_id = $_POST['user_id'];
$post_id = $_POST['post_id'];
$comment = mysql_real_escape_string($_POST['comment']);
$date = mktime();
mysql_query("INSERT INTO comments SET user_id='$to_id', from_id='$session', post_id='$post_id', comment='$comment', date='$date'");
$id = mysql_insert_id();



$query = mysql_query("SELECT * FROM comments WHERE post_id='$post_id' AND from_id!='$session' AND state='0' GROUP BY from_id");
if(mysql_num_rows($query)>0)
{
$row1 = mysql_fetch_assoc(mysql_query("SELECT * FROM posts WHERE id='$post_id'"));
$post_from2 = $row1['from_id'];
mysql_query("INSERT INTO notifications SET user_id='$post_from2', from_id='$session', post_id='$id', action_type='4', date='$date'");

while($row = mysql_fetch_array($query))
{
$post_from = $row['from_id'];
if($post_from!=$post_from2)
{
mysql_query("INSERT INTO notifications SET user_id='$post_from', from_id='$session', post_id='$id', action_type='4', date='$date'");
}
}

}
else
{
$row1 = mysql_fetch_assoc(mysql_query("SELECT * FROM posts WHERE id='$post_id'"));
$post_from = $row1['from_id'];
mysql_query("INSERT INTO notifications SET user_id='$post_from', from_id='$session', post_id='$id', action_type='4', date='$date'");
}

$query = mysql_query("SELECT * FROM comments WHERE id='$id' AND state='0'");
comments($query);
}
?>

What does this code do/mean?

 /*

Hi

I'm wondering how I can output nested comments.

I have written a viewthread.php file that works nicely so far. From index.php it gets the IDOfThread and passes this to a $number then outputs all the comments assigned to the Thread ID

However I'd like to be able to respond to each comment to create nested comments

This is my viewthread.php so far

And this is what it looks like

I think I would probably change the margin of the responses to jut them in a bit and am thinking the best way would be to create a function that cycles through and where it finds a ParentId of a comment matching the Posts.id it would then put this beneath it?

My comments are stored in a table titled Posts and Posts looks like
