PHP - List All Queries

Hey guys - me again!

I have a discount box, where i wish to check two "if" queries.  These are i) the 'uniquecode' and ii) the 'uses' - so a code can only be used a set amount of times.

1) How do i state that question in php, bearing in mind the "if uses > 0" needs to relate to the same row as the unique code entered?

2) Also, i have stored the session price in $_SESSION['sessionprice'] - is this the best way to do this, and if not how should i store the current price. 

3) Lastly, and how do I do the php mathematics of "$_SESSION['sessionprice'] minus the discount" - again bearing in mind the "discount" needs to relate to the same row as the unique code entered? (as different codes will have different discounts).


This is how far i've gotten:

Code: [Select]
<?php
//connection settings bla bla bla

$uniquecode = $_POST['discountcode'];

mysql_connect($localhost,$username,$password);
@mysql_select_db($database) or die( "Unable to select database");

$discountcodecheck = mysql_query("SELECT uniquecode FROM discounttable WHERE uniquecode = '".$uniquecode."'");
$remainingusescheck = mysql_query("SELECT uses FROM discounttable WHERE uniquecode = '".$uniquecode."'");

if (mysql_num_rows($discountcodecheck) > 0) and if (mysql_num_rows($remainingusescheck) > 0)  // <-- this "and if" doesn't work
{
// discount calculation:
// session price minus the unique code's corresponding discount
// update $_session['discountammount']

}
else
{
?><script type="text/javascript">
alert("Discount Code Entered Is Either Not Valid Or Has Been Previously Used.");
        history.back();
      </script><?php
}

// rest of code and close connection
?>

Any help or comments will, as always be politely welcomed and appreciated

Cheers,

Tom.

how can i join the two queries so that they function as one. for example, if $keywords or $username is empty then the result will be null.

$query1 = "SELECT * FROM forums WHERE MATCH (topics) AGAINST ('$keywords' IN BOOLEAN MODE)";

$query2 = "SELECT * FROM users WHERE username='$username";

I'm trying to figure out how to combine these queries, to decrease server load and load time, but I'm not so good with MySQL queries. Does anyone have any ideas, any help is greatly appreciated, I've been tinkering with this for days now.

$Actv = 0;
$ActvCount = -1;
$ActvUpgrade = 0;

Hi, I am trying two compare to dates but have not been successful.

A row is filled in Mysql database called htime with   $check=mktime(17,0,0,04,10,2011);

My first question is  that in the mktime function I have entered 17 which is hours. I would like to know if thats like the 17th hour of the given day or thats not how it works?

My second question is it a valid query to use <= or >= or < in a  mysql query for example.

$query="SELECT * FROM hdb WHERE htime <='".time()."'";

Thirdly I want to know if a row is filled with mktime(17,0,0,04,10,2011);  for example How can I only extract the day from the database based on the time has passed? This is because my own query doesnt seem to be working which is the query above I have no errors but the results dont seem to be right. Any help is much appreciated thanks.

Hi there everyone!

I've got a problem combining two queries. The situation is this. I've got a list of links and I want to allow the user to get a result list of all, only unread, all in a particular category and then only unread in a particular category.

My query for all:
 

/* No filtering and no unread */
$q_urls = "SELECT * FROM shortenified_urls WHERE is_social = '1' AND active = '1' ORDER BY date_added DESC";

My query for in a particular category:
 

/* All links in a particular category */
$q_urls = "
SELECT * FROM shortenified_urls
WHERE shortenified_urls.primary_cat = $vu_cat_view
OR EXISTS (
SELECT link_id FROM linkcats
WHERE link_id = shortenified_urls.id AND cat_id = $vu_cat_view
)
AND shortenified_urls.is_social = '1' AND shortenified_urls.active = '1'
ORDER BY date_added DESC"
;

My query for Unread in all cats:
 

/* Unread only for all categories */
$q_urls = "SELECT * FROM shortenified_urls
WHERE shortenified_urls.date_added > $vu_mark_as_read
AND NOT EXISTS (
SELECT lid FROM linkviews
WHERE lid = shortenified_urls.id AND uid = $viewing_user_id
)
AND shortenified_urls.is_social = '1' AND shortenified_urls.active = '1'
ORDER BY date_added DESC"
;

These seem to be working well. It's the next one that isn't working for me. I tried to combine the "All in a particular category" and "Unread in all categories" using the two above as starting points. The result, however, seems to be that I'm getting all in a particular category. It seems to be ignoring the unread status.
 

/* Unread links in a particular category */
$q_urls = "
SELECT * FROM shortenified_urls
WHERE shortenified_urls.primary_cat = $vu_cat_view AND shortenified_urls.date_added > $vu_mark_as_read
OR EXISTS (
SELECT link_id FROM linkcats
WHERE link_id = shortenified_urls.id AND cat_id = $vu_cat_view
)
AND NOT EXISTS (
SELECT lid FROM linkviews
WHERE lid = shortenified_urls.id AND uid = $viewing_user_id
)
AND shortenified_urls.is_social = '1' AND shortenified_urls.active = '1'
ORDER BY date_added DESC"
;

I'm not smart enough to know why it's not working, but it seems to me like I need to somehow bracket the first two parts containing the category retrieval to make this work right. The only problem is I don't know how to do that.

Any help on how to get this to work would be greatly appreciated!

Hello, in short, here is my problem:

There are 2 tables:

a table called postcodes, which contains UK postcodes
and a table called wp_bp_xprofile_data (i want to integrate this search with the Buddypress plugin's tables) which contains the user data.

I tried searching this, but to be honest, i didn't quite know how to go about it..



Here is what i have:

$query1 = "SELECT value, user_id, (SQRT(POW((b.x - a.x), 2) + POW((b.y - a.y), 2))/1000) * 0.621 AS distance
    FROM postcodes a, postcodes b, wp_bp_xprofile_data
    WHERE a.outcode = '"$postcode"' AND b.outcode = wp_bp_xprofile_data.value
    HAVING (distance < '"$area"')
    ORDER BY distance asc ";


$result1=mysql_query($query1) or die(mysql_error());

        echo "<p style=\"font-size:10px;line-height:14px;color:#888;\">Straight line distances shown.<br>";
        echo "<table border=\"0\" cellspacing=\"0\" cellpadding=\"0\" width=\"100%\" ><tr>";

        // display results
        while ($list = mysql_fetch_array($result1)) {
        $user_postcode = $list['value'];
        $distance = $list['distance'];
        $distance = round($distance);

   echo "<td align=\"right\">$distance miles away</td></tr>";
   echo "<tr><td colspan=\"3\" align=\"left\" width=\"130px\">$user_postcode </td>";
   echo "<td align=\"right\"><a href=\"blahblah\">Directions using Google Maps</a></td>";
   echo "<tr><td align=\"left\">&nbsp;</td><tr>";
        echo "</tr>";
}
echo "</table>";


Code: ("wp_bp_xprofile_data") [Select]
id field_id user_id value
1 1          1 admin
8 3          3 NW10
6 1          3 Test User 1
9 4          3 IT, Web Development
11 1          4 Test User 2
12 3          4 HA5
13 4          4 Test, It, Some Work
Code: ("postcodes") [Select]
outcode x y latitude longitude
B10 392900 804900 57 -2
AB11 394500 805300 57 -2
AB12 393300 801100 57 -2
AB13 385600 801900 57 -2
AB14 383600 801100 57 -2


Here is an example of what i need:

field_id "3" corresponds to a postcode. My script so far, can search a postcode and return results with the postcodes sorted by distance. What i'm trying to do, is also get the username on the result (i.e the 'value' column again..).

in short, im trying to search a postcode, find it on wp_bp_xprofile_data, associate it with the correspondent user, and return both.  Someone told me i need to INNER JOIN, but im lost..



The end result im looking for is if i type the search: "NW9 1AA"

It returns:

Test User 1
NW10
 

Test User 2
HA5   
(the code sorts them by distance. So far i can get it to return the postcode, but cannot associate the relevant name.

Can anyone help me with this?
I hope this is in the right forum.

Thanks for your attention.

Hi all,

I've built a few amateur sites in the past but am keen to utilize php combined with mysql for my current project.  However, I have little knowledge of php and am just picking it up as I go (same way I've done for all my computer knowledge)

What I'm looking for may sound simple, but I really don't know where to start and I'm hoping there are some kind souls here that will lend a hand.  I've got some fantastic help here before and am hoping I'll get lucky again.

SQL Database
meetingid venue
001 new york
002 chicago
003 new york
004 new york
005 new york
006 texas
007 texas
008 chicago
009 new york
010 new york

Question
If I hard code everything around it, I'm just looking for the code I would need to have it display as follows: (hard coded text in blue)

"New York has been used * times." 
(Where * would count the number of times "New York" appears in the venue column of the database.)
"The most consecutive times New York has been used is % ." 
(Where % would count the maximum number of consecutive times "New York" appears in the venue column of the database.)

Giving the output:
New York has been used 6 times.
The most consecutive times New York has been used is 3.

I need two queries cause I don't know how to put them into one. Problem here is I need to know the field Liters from the database in the first query to subtract it from the second query to be able to calculate the average fuel consumption of the chosen range.   This is my code, hope you can help

function getContent() {
	include 'connection.php';

$dx = date('m', strtotime('today - 30 days'));	

	if (!isset($_POST["month_select"])) {
		$month = $dx;
		$year = "2014";
	}
	else {
		$month = $_POST["month_select"];
		$year = $_POST["year_select"];
	}

//last fuel fill value 
		$query2 = "SELECT d.liter as FirstFill 
  FROM members AS m
LEFT OUTER
  JOIN diesel AS d
    ON d.userid = m.id
   WHERE YEAR(dato) = $year AND MONTH(dato) = $month AND d.liter > 0 ORDER BY d.id ASC LIMIT 1";

		$sql2=$oDB->prepare($query2);
		$sql2->execute();
		$row2 = $sql2->fetchAll();
    return $row2;
	
    $FirstFill = $row2['FirstFill'];
	
		$query = "SELECT m.username, m.id, 10 * (SUM(d.liter) - $FirstFill) / (MAX(d.km) - MIN(d.km)) as AvgFuel

I've been playing around with PDO lately, and I've been trying to get use to the basic functions as I've mentioned in some of my other posts/questions. Recently I switched to the ? bind/token (can't remember it's called), so I reformatted my processQuery. I've also tried to add in a fetching option in the method, but I can't seem to get anything to work.

I've looked up several internet tutorials but it seems like I'm doing everything the same. Yet, the query doesn't seem to run. :/

$database->processQuery2("INSERT INTO test (test, testa) VALUES (?, ?)", array('noob', 'newb2'), false);

Now for my method:


public function processQuery2($query, array $binds, $fetch)
    {
        $query_handle = $this->dbc->prepare($query);
        
        if(count($binds) > 0)
        {
            $i = 1;
            $value = array();
            
            foreach($binds as $bind)
            {
                $query_handle->bindParam($i, $value[$i]);
                $value[$i] = $bind;
                $i++;
            }
        }
        $query_handle->execute();
        
        //if($fetch == true)
        //{
            //return $query_handle->fetchAll();
        //}
    }


Any reasons to why it's not working? No errors are outputted, either.

whats the differance between

mysql_query("UPDATE banned SET time

and doing

$safe4 = "UPDATE banned SET time
mysql_query($safe4);


is there a reason as to why do it the 2nd way i mentioned?

if someone could please explain it to me so i wont be in confusion on this anymore

This must be easy enough, but I'm a noob so go easy on me, please :-)   I have two pieces of code and they're working well on their own. All I need is to put these two conditions into one query.   The first one:

<?php
function childtheme_cat_limited_blog( $query ) {
    if ( $query->is_home() && $query->is_main_query() ) {
        $query->set( 'events_categories', 'mycategory1' );
    }
}
add_action( 'pre_get_posts', 'childtheme_cat_limited_blog' );
?>

And the second:

<?php
function childtheme_cat_limited_blog( $query ) {
    if ( $query->is_home() && $query->is_main_query() ) {
        $query->set( 'category_name', 'mycategory2' );
    }
}
add_action( 'pre_get_posts', 'childtheme_cat_limited_blog' );
?>

I'm sure it's a piece a cake for you guys, but I can't figure it out for the life of me, so any help would be greatly appreciated!   Thank you!   (My goal is here to display posts from two categories on a homepage of a Wordpress site, but to complicate things the two categories are from two different post types.)

Here is the original query:

Code: [Select]
$query_extract = mysql_query("SELECT downloads,date,title,username,views,id FROM skins ORDER BY id DESC LIMIT 100");

Is it possible to also grab the row username from the table users, without making multiple queries?

The first query goes through but the second does not just seeing if I'm missing something.

<?php

// Include the database page
require ('../inc/dbconfig.php');

if (isset($_POST['submittitle'])) {
    $titlename = mysqli_real_escape_string($dbc, $_POST['titlename']);
    $titleshortname = mysqli_real_escape_string($dbc, $_POST['titleshortname']);
    $titlestyle = mysqli_real_escape_string($dbc, $_POST['titlestyle']);
    $titlestatus = mysqli_real_escape_string($dbc, $_POST['titlestatus']);

    $query = "INSERT INTO `titles` (titlename, titleshortname, style_id, status_id, creator_id, datecreated) VALUES ('$titlename','$titleshortname','$titlestyle','$titlestatus', 1, NOW())";
    mysqli_query($dbc, $query);
    $query_id = mysqli_insert_id($dbc); 
    $query1 = "INSERT INTO `champions` (title_id) VALUES ('$query_id')";
    mysqli_query($dbc, $query1);  
}
?>
