$mysql_database = "XXXXXXX";

$connection = mysql_connect("$host","$mysql_user","$mysql_password") or die ("Unable to connect to MySQL server.");
mysql_select_db($mysql_database) or die ("Unable to select requested database.");

Getting Selective Data From Mysql And Ordering It In A Table!

Ok I was wondering is there a way I can select a mysql database, and order it but only show data of a certain criteria: for example

Mysql database:
ID | User | XP | Won | Lost
1 Freid 100 1 4
2 Smic 300 5 4
3 Retna 300 3 2
4 OBW 200 3 2

And then some php code that will retrieve this information but only display the users that have lost = 4 in a list. In other words some php code that will only list the players Freid and Smic from the msql database becuase they have Lost = 4 the code would not show Retna or OBW becuase there Lost is not = to 4

Any help would be great thanks

Retrievin Data From Data Base .. Based On The Logged In User

View Content

I have two tables.

Table Name:Users

Fields:

User_name
user_email
user_level
pwd

2.Reference

Fields:

refid
username
origin
destination

user_name in the users table and the username field in reference fields are common fields.

There is user order form.whenever an user places an order, refid field in reference table will be updated.So the user will be
provided with an refid

Steps:

1.User needs to log in with a valid user id and pwd
2.Once logged in, there will be search, where the user will input the refid which has been provided to him during the time of order placement.
3.Now User is able to view all the details for any refid
3.Up to this we have completed.

Query:

Now we need to retrieve the details based on the user logged in.

For eg: user 'USER A' has been provided with the referenceid '1234' during the time of order placement
user 'USER B' has been provided with the referenceid '2468' during the time of order placement

When the userA login and enter the refid as '2468' he should not get any details.He should get details only for the reference ids which is assigned to him.

<?php

session_start();

if (!$_SESSION["user_name"])



{
        // User not logged in, redirect to login page
        Header("Location: login.php");
     }
$con = mysql_connect('localhost','root','');
if (!$con)
  {
  die('Could not connect: ' . mysql_error());
  }

mysql_select_db("login", $con);
$user_name = $_POST['user_name'];
$refid = $_POST['refid'];
$query = "SELECT * from reference,users WHERE reference.username=users.user_name AND reference.refid='$refid' AND ";

$result = mysql_query($query) or trigger_error('MySQL encountered a problem<br />Error: '  . mysql_error() . '<br />Query: ' . $query);

while($row = mysql_fetch_array($result))
  {
  echo $row['refid'];
  echo $row['origin'];
  echo $row['dest'];
  echo $row['date'];
  echo $row['exdate'];
  echo $row['username'];
  }
echo "<p><a href=\"logout.php\">Click here to logout!</a></p>";
?>

<html>
<form method="post" action="final.php">
Ref Id:<input type="text" name="refid">
<input type="submit" value="submit" name="submit">
</html>

Why Query Fails To Pull All Data From Data Base ?

Hi,

I want to pull data from db, where sometimes all rows and sometimes rows matching given "username".

Here is my code:

	//Grab Username of who's Browsing History needs to be searched. 
	if (isset($_GET['followee_username']) && !empty($_GET['followee_username'])) 
{ 
    $followee_username = $_GET['followee_username']; 
    
    if($followee_username != "followee_all" OR "Followee_All") 
    { 
        $query = "SELECT * FROM browsing_histories WHERE username = \"$followee_username\""; 
        $query_type = "followee_username"; 
        $followed_word = "$followee_username"; 
        $follower_username = "$user"; 
        echo "$followee_username"; 
    } 
    else 
    { 
        $query = "SELECT * FROM browsing_histories"; 
        $query_type = "followee_all"; 
        $followed_word = "followee_all"; 
        $follower_username = "$user"; 
        echo "all"; 
    } 
}

When I specify a "username" in the query via the url:

browsing_histories_v1.php?followee_username=requinix&page_number=1

I see result as I should. So far so good.

Now, when I specify "all" as username then I see no results. Why ? All records from the tbl should be pulled!

browsing_histories_v1.php?followee_username=all&page_number=1

This query shouldv'e worked:

	$query = "SELECT * FROM browsing_histories";

Data Not Properly Displayed In Html Table By Using While Loops To Fetch Data From Mysql Database

Similar Tutorials

View Content

Hello to all,

I have problem figuring out how to properly display data fetched from MySQL database in a HTML table.

In the below example I am using two while loops, where the second one is nested inside first one, that check two different expressions fetching data from tables found in a MySQL database. The second expression compares the two tables IDs and after their match it displays the email of the account holder in each column in the HTML table.

The main problem is that the 'email' row is displayed properly while its while expression is not nested and alone(meaning the other data is omitted or commented out), but either nested or neighbored to the first while loop, it is displayed horizontally and the other data ('validity', 'valid_from', 'valid_to') is not displayed.'

Can someone help me on this, I guess the problem lies in the while loop?
Here is part of the HTML code:

<thead>
 <tr>
 <th data-column-id="id" data-type="numeric">ID</th>
 <th data-column-id="email">Subscriber's Email</th>
 <th data-column-id="validity">Validity</th>
<th data-column-id="valid_from">Valid From</th>
 <th data-column-id="valid_to">Valid To</th>
</tr>
</thead>

Here is part of the PHP code:

    <?php
    while($row = $stmt->fetch(PDO::FETCH_ASSOC))
    {
        echo '
            <tr>
                <td>'.$row["id"].'</td>
        ';
        while ($row1 = $stmt1->fetch(PDO::FETCH_ASSOC)) {
        echo '
                <td>'.$row1["email"].'</td>
        ';
        }
        if($row["validity"] == 1) {
            echo '<td>'.$row["validity"].' month</td>';
        }else{
            echo '<td>'.$row["validity"].' months</td>';
        }
        echo '  <td>'.$row["valid_from"].'</td>
                <td>'.$row["valid_to"].'</td>
        </tr>';
    }
    ?>

P.S. Please know that I have purposely omitted the connection part and the methods in the class that are used in this code to keep the spot of the problem as clean as possible. If you need me to rephrase the question, please ask.

Thank you.
