PHP - Adding To A Join Query

Sorry, I originally posted part of this in MYSQL Help, but I was advised to post it here. I'm hoping someone can help me out.

I have 2 tables. "categories" and "subcats" (sub categories). I used a JOIN query for both..

Code: [Select]
SELECT categories.*, subcats.* FROM categories JOIN subcats on (categories.cat_id = subcats.cat_id) ORDER BY cat_name
Then I used a while loop to echo all the categories from the "categories" table and their respective sub-categories from the "subcats" table.

$sql = "SELECT categories.*, subcats.* FROM categories JOIN subcats on (categories.cat_id = subcats.cat_id) ORDER BY cat_name";
$cats_result = $connection->query($sql) or die(mysqli_error($connection)); 

    while ($row = $cats_result->fetch_assoc()) { 
$cat_id = $row['cat_id'];
$cat_name = $row['cat_name'];
$subcat_name = $row['subcat_name'];

       //should output all categories once and nest their subcategories
echo "<strong>".$cat_name."</strong>"; 
echo "<br />";
echo $subcat_name; 
echo "<br />";

}

No MYSQL errors but unfortunately I get this output..

What sort of code can use in the loop to echo categories just once instead of multiple times for each topic?

I was running this query and feel this is slowing down the server:

Code: [Select]
$agent_query=$this->db->query("
                       SELECT u.id,u.name,u.team_id,l.agent_id from users AS u,leads AS l WHERE u.id=l.agent_id AND u.team_id
                        IS NOT   NULL AND u.is_active='1'
ORDER BY u.name ASC
");
Is there a better way to write the above code.

I am using two seperate queries to calculate a streak, but the queries must be grouped together to find the actual streak?

Query 1:

SELECT COUNT(matchID) as streak, clan1 FROM webs_cup_matches WHERE ladID='17' AND clan1='2630' AND score1 > score2 AND confirmscore='1' AND einspruch='0' GROUP BY clan1 ORDER BY streak DESC LIMIT 1
Query 2:
SELECT COUNT(matchID) as streak, clan2 FROM webs_cup_matches WHERE ladID='17' AND clan2='2630' AND score1 < score2 AND confirmscore='1' AND einspruch='0' GROUP BY clan2 ORDER BY streak DESC LIMIT 1

is it possible someone can join these queries together?

It's been a while since I sat down to build some pages and teach myself php. So now that I've started back up, I'm at a loss for what I've done. I deleted a file, and have to rebuild from an old broken version:

I have a form that submits a query to the database, but the results pages is giving me this error:

Code: [Select]
Oops, my query failed. The query is:
SELECT COUNT 'descriptors'.* ,'plantae'.* FROM 'descriptors' LEFT JOIN 'plantae' ON ('descriptors'.'plant_id' = 'plantae'.'plant_name') WHERE 'leaf_shape' LIKE '%auriculate%' AND 'leaf_venation' LIKE '%%' AND 'leaf_margin' LIKE '%%'
The error is:
You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '.* ,'plantae'.* FROM ' at line 2
But I'm not seeing what the syntax error is.

Here's the code:
Code: [Select]
<?php 
require ('connection.php');

$display = 2;
// it's intentionally only 2 for the moment

if (isset($_GET['np'])) {

$branchmail = $row->Email ;

$query = "SELECT $usrlang FROM autoreplies WHERE ReplyID = '0'" ;
include("dbconnectlocal.php") ;
$result = mysql_query($query) or die(mysql_error()) ;

hi,

Hi,

This is probably very easy for someone who knows how but I cant seem to get it working.

Can someone please tell me how I can alter this query to select a 'WHERE gender = female' so instead of picking a random user it picks a random female user ?

Code: [Select]
$offset_result = mysql_query( " SELECT FLOOR(RAND() * COUNT(*)) AS `offset` FROM `users` ");
$offset_row = mysql_fetch_object( $offset_result );
$offset = $offset_row->offset;
$user1b = mysql_query( " SELECT * FROM `users` LIMIT $offset, 1 " );
$user1= mysql_fetch_array($user1b);

Also, would it be easy to modify it so it picks a second random user that isnt the same as the first user ? so I end up with 2 random females ( $user1 and $user2 )

Many thanks,

Scott

Is it possible to add a query string for example some_var=jk84 to any sort of link be it, http://www.website.com , http://www.website.com/?some_id=4, or http://www.website.com/post=45&category=9 or http://www.website.com/somepost/ ?

While adding that extra query string how can I make sure I'm not affecting the website's content or causing some script error?

If ($_GET['CODE'] == '1') {
    $ThreadID = mysql_escape_string($_GET['threadid']);
    $ForumID = mysql_result(mysql_query("SELECT forum_id FROM ".FORUM_THREADS." WHERE thread_id='{$ThreadID}'", $db), 0, 'forum_id');
    $PostText = mysql_escape_string($_POST['replytext']);
    $IP = $_SERVER['REMOTE_ADDR'];
    $PostQuery = "INSERT INTO ".FORUM_POSTS." (`user_id`, `thread_id`, `post_text`, `forum_id`, `ip_address`, `timestamp`) VALUES ('{$memid}', '{$ThreadID}', '{$PostText}', '{$ForumID}', '{$IP}' , CURRENT_TIMESTAMP)";
    $PostRes = mysql_query($PostQuery, $db);


For some reason whenever this query goes through, it also adds a blank result using all the same information but without any $PostTest so essentially it does query:

Code: [Select]
INSERT INTO ".FORUM_POSTS." (`user_id`, `thread_id`, `post_text`, `forum_id`, `ip_address`, `timestamp`) VALUES ('{$memid}', '{$ThreadID}', '', '{$ForumID}', '{$IP}' , CURRENT_TIMESTAMP)

This is the only query that does this part of the code and I can't see why it is adding 2 queries.

FORUM_POSTS = constant containing table name.

So I have this snippet of code:

Code: [Select]
             

                $row['ratings'] = "";


                        $ratingsSQL = $this->ipsclass->DB->query(
                                                                "SELECT `pid` , `rating` , COUNT(`rating`) as ratings
                                                                FROM `ibf_ratings`
                                                                WHERE `pid` = '" . $row['pid'] . "' GROUP BY `rating`
                                                                ");

                        $i = 0;
                        $ratingshtml = "";

                        if( $this->ipsclass->DB->get_num_rows( $ratingsSQL ) )
                        {
                                while( $rrow = $this->ipsclass->DB->fetch_row( $ratingsSQL ) )
                                {
                                        $ratingshtml .= "<div class=\"rate_it_display\" style=\"background-image: url( 'style_images/rate/" . str_replace( ' ' , '' , strtolower( $this->ratings[$rrow['rating']] ) ) . ".png' ) \"> " . $rrow['ratings']. " x " . $this->ratings[$rrow['rating']] . "!</div>";
                                        $i++;
                                }

                                $ratingshtml .= "<a href=\"#\" onclick=\"return RateItExpand( {$row['pid']} );\" style=\"color: #999;\">(list)</a>";

                        }

                        $row['ratings'] = $this->ipsclass->compiled_templates['skin_topic']->ratings( $row['pid'] , $row['author_id'] , $ratingshtml );
I want to add an if statement to the code so that the ratings won't load unless a user clicks a button at the top of the screen.  Can anyone help me with this?  I'd be very appreciative.  Thanks in advance.

Greetings,

I need a bit of php coding help.  I have a query that gives me results.  What I need to do is take those results and, I think, use php to compare the results and add a 1 to the correct section.

Example:

3 tables
table name- retail_sales
id
sales_id
amount
week

table name- online_sales
id
sales_id
amount
week

table name- sales_person
sales_id
name

I have the query that breaks down results by week:

week 1 | retail_sales.amount | online_sales.amount

What I need is some php code that will then compare the two together and:
 if retail_sales.amount > online_sales.amount +1 to retail
OR if retail_sales.amount < online_sales.amount +1 to online

so you would end up with a result like a sports record (6-2)

Any ideas

Thank you for any help

I need to add likes_username to this query and use a DISTINCT on it.   It currently counts how many likes a status has but in the table there are some statuses with multiple likes from the same username. 

SELECT s.*, COUNT(l.likes_location_id) AS likeCount
 FROM stream AS s
  LEFT JOIN likes AS l ON ( l.likes_location_id = s.stream_id )
 GROUP BY s.stream_id
 ORDER BY s.stream_id DESC LIMIT 50

Many thanks,
