PHP - Join Query Slowing Down The Server

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 am having a warning which indicates there is a not valid mysql result, I think the problems lay down at the WHERE clause, but I am not sure.

Warning: mysql_num_rows(): supplied argument is not a valid MySQL result resource in /storeprueba/sidebar.php on line 21

Code: [Select]

$categoryurl = $_GET['categoryurl'];
$sql= mysql_query("SELECT * FROM products, categories WHERE products.category = '$categoryurl' DESC LIMIT 6");
$productCount = mysql_num_rows($sql); // line 21
if ($productCount>0 )
     {
     while($row = mysql_fetch_array($sql))
          {
            $id= $row["id"];
$product_name= $row["product_name"];
$price = $row["price"];
$category = $row["category"];
$subcategory = $row["subcategory"];
$location = $row["location"];
$date_added = strftime("%b %d, %Y", strtotime($row["date_added"]));


thanks.

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

Is there a cleaner way to do this?

include("dbconnectlocal.php") ;
$result = mysql_query($query) or die(mysql_error());

$row = mysql_fetch_object($result) ;

$branchmail = $row->Email ;

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

$row = mysql_fetch_object($result) ;

hi,

This topic has been moved to MySQL Help.

http://www.phpfreaks.com/forums/index.php?topic=308855.0

I have a PHP web system that store in a windows server. In the system, there is a function for user to upload files to another server (Shared server in Unix).

When i try to upload a file, it gives warning:

Warning: move_uploaded_file(\\unixserver/sharedfolder/upload/test.txt) [function.move-uploaded-file]: failed to open stream: Permission denied in C:\wamp\www\upload\index.php on line 40

For your information, my username has been assigned in xxx's group that has access to read and write on that folder. Besides, i'm able to open,create and delete files on that folder's server manually (samba).

The safe mode setting is off.

Does anybody has any idea why this thing happen?

Hi,  I am not a PHP programmer.

I took on a new client with a simple PHP site, without any databases.
The site is up and running on the web.
I would like to get it running on my local machine for further development.
I have latest version of WAMP installed, running Apache version 2.2.11 and PHP version 5.3.0
I created a directory in the WAMP "www" project directory and it shows up there like it's supposed to when I browse to "localhost"

Problem:

The home page of website displays text but no, images, styles, footer, header, nav links, etc.


Here is the code for the home page:

<?
  define("NAV","home");
require_once('local/local.php');
?>

Any help would be greatly appreciated. I have spent many hours on this.

I'm trying to make a simple website where people register to my website.

When the user doesn't fill anything inside the boxes they get a message "Please fill all required fields" on the register.php page

On my local host require_once works good. It shows up.

 

But when i upload the files to my sever the require_once does not show up on the register.php

It just refreshes and i dont get the message "Please fill all required fields"

 

This is the code that works in local host but not in a live server

<?php require_once 'messages.php'; ?>

 

 

Here is my full code

 

Register page:

<html>


<?php require_once 'messages.php'; ?>

<br><br>


<form action="register-clicked.php" method="POST">

Username:<br>
<input type="text" name="usernamebox" placeholder="Enter Username Here">
<br><br>
Email:<br>
<input type="text" name="emailbox" placeholder="Enter email here">
<br><br>
Password:<br>
<input type="password" name="passwordbox" placeholder="Enter password here">
<br><br>
Confirm Password:<br>
<input type="password" name="passwordconfirmbox" placeholder="Re-enter password here">
<br><br>

<input type="submit" name="submitbox" value="Press to submit">
<br><br>

</form>

</html>

 

 

Register clicked

<?php


session_start();



$data = $_POST;

if( empty($data['usernamebox']) ||
    empty($data['emailbox']) ||
    empty($data['passwordbox']) ||
    empty($data['passwordconfirmbox'])) {
    $_SESSION['messages'][] = 'Please fill all required fields';
    header('Location: register.php');
    exit;

}




if ($data['passwordbox'] !== $data['passwordconfirmbox']) {
    $_SESSION['messages'][] = 'Passwords do not match';
    header('Location: register.php');
    exit;
}


$dsn = 'mysql:dbname=mydatabase;host=localhost';
$dbUser='myuser';
$dbPassword= 'password';

try{
$connection = new PDO($dsn, $dbUser, $dbPassword);
} catch (PDOException $exception){
    $_SESSION['messages'][] = 'Connection failed: ' . $exception->getMessage();
    header('Location: register.php');
    exit;
}

 

 

messages.php

<?php
session_start();

if (empty($_SESSION['messages'])){
    return;
}

$messages = $_SESSION['messages'];
unset($_SESSION['messages']);
?>



<ul>
    <?php foreach ($messages as $message): ?>
        <li><?php echo $message; ?></li>
    <?php endforeach; ?>

Hi folks,

I'm curious if I can for example, save a file from my server and it will save to all other servers - obviously if they accepted the connection first. It's for a software I developed and is almost complete and know there will be frequent updates to it. Instead of users downloading upates, I want the update files from my server to somehow synchronize to their server automatically?

Anything called this??

Thanks for info.

This isn't exactly an application design question, but rather a system design one.   I am about to install an Inventory Control System inside this store I work in.   The store itself also owns a Linode VPS running Centos 6.4 which hosts our website.   This new Inventory System will come built in with a Microsoft SQL Server, and supposedly it is a SQL Anywhere database, but I'm not too sure what that means.     I need to make this database publicly accessible, but only via the Linode VPS.  Surely, setting restrictions is easy enough to address that issue.  That isn't my question.   My first idea is to put this server into the DMZ, easy.  But it doesn't exactly sound safe.  So my next idea was to put a middleman server in the DMZ, this way the Linode can send queries to that middleman server and it will send that data to the SQL Server and back.  This is very vaguely described I know, but I don't want to get too much into details, but rather, understand how I can create that middleman server, and what could Install onto it that would allow me to securely process queries?   My first thought was to install a webservice, that accepts an XML/JSON request and returns an XML/JSON response. Then, I realized directly afterwards that I don't have any experience setting up a webservice like that. What kind of options are there out there?
  Ultimately, my question is, should I just put the Server in the DMZ or should I create the middleman, and if so, can someone point me in the right direction as to getting a webservice set up?

Following a tutorial on udemy, i tried to learn the very basics of mvc structure. I built the same project on my local server and it worked without giving me any error. but when i tried it on live server. its not working as it should. not showing any error. I tried to figure out the problem and found that for every page loading, it stops at the same line in my main.php file.

<?php require($view); ?>

starting from the above line. it stops. i came here to share my problem but i am unable to upload my files here. if there is a way to upload and share my files, please guide. zip file size of the whole project is 31.6 kb
