PHP - Linking Related Table Data With Php/mysql

Hello,

I know i'm new, i hope it wont stop you guys from putting 5 minutes of your time to help me out.
I need a script to get some data from mysql and put this into a table.

i have a mysql database called "denora"
In there is a table called "chan"
In table chan are the columns: chanid (unique number), channel, currentusers, mode_ls

I would like the script to make a html table that lists the top10 channels (most "currentusers" on top)
And when "mode_ls" is "Y" it must not be shown (secret channel)

My knowledge of php and mysql arent that great so i really hope someone takes the time to help me uit

Kind regards
Stefan

I am trying to get specific data from a MySQL table but cannot seem to find a proper command.

Code: [Select]
                $link = mysqli_connect('#####', '########', '########');
$user = $_SESSION['username'];
$email = mysqli_query($link,"select email from members where username='$user'");
echo $email;

Specifically, I am trying to get the email address stored for the user specified by the session, and display that address.
However, I do not get any output with the current code, and am not sure what to try next. I have tried mysqli_fetch_row() but it only returns an error.

Hi all,
I'm new to php/myslq and I'm going crazy trying to figure this one out

I'm building a personal calendar and I want to display the data into a HTML table.

Code: [Select]
//query the database
$query = "SELECT * FROM tbl_events WHERE event_day=$day AND event_month=$month AND event_year=$year";
$query = mysql_query($query);

//build the table
echo '<table>';
for ($y = 0; $y < 6; $y++){
   echo '<tr><td>';
        //insert the data here
   echo '</td></tr>';
}
echo '</table>';

When I store the events into the database, I assign a slot for each one depending on the hour. I don't want to use more than 6 events daily, hence the for loop. The problem I have is how to I insert the data into the designed <td>? In a particular day I could have only 2 events: event 1 - slot 2, event 2 - slot 6. I want to be able to enter each event into its own cell

I hope I'm making myself clear enough. Sorry for any English mistakes if any.

Thank you

Hello guys, im using this code atm and it's working, but the new rows created are put in the end of the table. I want them to stack up from the beginning pushing older rows down. What should i do to make that work?


<?php
$con = mysql_connect("localhost","*****","*******");
if (!$con)
  {
  die('Could not connect: ' . mysql_error());
  }

mysql_select_db("ananaz_se", $con);

$sql="INSERT INTO stuff (adult, namn, url)
VALUES
('$_POST[adult]','$_POST[namn]','$_POST[url]')";

if (!mysql_query($sql,$con))
  {
  die('Error: ' . mysql_error());
  }
echo "1 row added";

mysql_close($con)
?>

Hi, I am extracting data from a mysql db to then edit and update back into the db and use below to list items first -

Code: [Select]
<?php

// Connect to server and select database.
mysql_connect('localhost', 'xxxxxxxxx', 'xxxxxxxxxxxxx') or die("Error: ".mysql_error());
mysql_select_db("xxxxxxxxx");

$sql="SELECT * FROM properties";
$result=mysql_query($sql);
?>
<table width="400" border="0" cellspacing="1" cellpadding="0">
<tr>
<td>
<table width="400" border="1" cellspacing="0" cellpadding="3">
<tr>
<td colspan="4"><strong>List data from mysql </strong> </td>
</tr>

<tr>
<td align="center"><strong>Name</strong></td>
<td align="center"><strong>Lastname</strong></td>
<td align="center"><strong>Email</strong></td>
<td align="center"><strong>Update</strong></td>
</tr>
<?php
while($rows=mysql_fetch_array($result)){
?>
<tr>
<td><? echo $rows['Property_Rating']; ?></td>



<td align="center"><a href="update.php?id=<? echo $rows['ID']; ?>">update</a></td>
</tr>
<?php
}
?>
</table>
</td>
</tr>
</table>
<?php
mysql_close();
?>

I then go next page where I show data and allow editing -
<?php

// Connect to server and select database.
mysql_connect('localhost', 'xxxxxxxxx', 'xxxxxxxxxxxxx') or die("Error: ".mysql_error());
mysql_select_db("xxxxxxxxx");

// get value of id that sent from address bar
$id=$_GET['id'];


// Retrieve data from database
$sql="SELECT * FROM properties WHERE id='$id'";
$result=mysql_query($sql);

$rows=mysql_fetch_array($result);
?>
<table width="400" border="0" cellspacing="1" cellpadding="0">
<tr>
<form name="form1" method="post" action="update_ac.php">
<td>
<table width="100%" border="0" cellspacing="1" cellpadding="0">
<tr>
<td>&nbsp;</td>
<td colspan="3"><strong>Update data in mysql</strong> </td>
</tr>
<tr>
<td align="center">&nbsp;</td>
<td align="center">&nbsp;</td>
<td align="center">&nbsp;</td>
<td align="center">&nbsp;</td>
</tr>
<tr>
<td align="center">&nbsp;</td>
<td align="center"><strong>Property_Name</strong></td>
<td align="center"><strong>roperty_Rating</strong></td>
<td align="center"><strong>Property_Address</strong></td>
</tr>
<tr>
<td>&nbsp;</td>
<td align="center"><input name="Property_Rating" type="text" id="Property_Rating" value="<? echo $rows['Property_Rating']; ?>"></td>

</tr>
<tr>
<td>&nbsp;</td>
<td><input name="id" type="hidden" id="id" value="<? echo $rows['id']; ?>"></td>
<td align="center"><input type="submit" name="Submit" value="Submit"></td>
<td>&nbsp;</td>
</tr>
</table>
</td>
</form>
</tr>
</table>

<?

// close connection
mysql_close();

?>

And then the update page -

<?php

// Connect to server and select database.
mysql_connect('localhost', 'xxxxxxxxx', 'xxxxxxxxxxxxx') or die("Error: ".mysql_error());
mysql_select_db("xxxxxxxxx");

// update data in mysql database
$sql="UPDATE properties SET Property_Name='$Property_Name' WHERE id='$id'";
$result=mysql_query($sql);

// if successfully updated.
if($result){
echo "Successful";

}

else {
echo "ERROR";
}

?>
Everything seems ok but when I edit the data and submit I get the success message but data not changed in db.

Any ideas?

Thanks.

The db has an table users with  id, login, password, site
Question how can i get inf from "site" raw  for logged user on  members.php   ( as a link).
Pls help thanks

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

Hello there!

I've been banging my head on  this for a while and I just  can't seem to get it to work properly.

I have a dropdown menu which selects information from table1 using a select statement (this table is called 'lid'). It selects the firstname, lastname and member id from this table and shows it in the dropdown menu. I'm glad I got that part working but the hard thing is inserting the data that the user selects into another table.  So when you select the id member from this dropdown menu it only inserts a blank row into table2 (which is called 'teamlid'). Can you guys help me? How can I insert the id member into my table2? What am I doing wrong here?

Thanks a million! This is my first post so if I'm doing anything wrong, let me know and I'll fix it asap!

Hi
I have a table (applicant) and I am looking at producing a pdf displaying various items of data from this table.

I have succeeded in getting the look I want but in my query I use a fixed applicantid (in this case an id of 4). What I want to be able to do is to have the id cary according to the url. In other words, when someone comes from one web page to this one and the url is of the format .../pdf_production.php?applicantid=42.

I'm not sure I've explained that very well but I hope someone can help - I think this is the last thing I need to sort out.

Many thanks in advance.

The code I have so far is:

<?php require_once('../Connections/process.php'); ?>
<?php
require_once('../tcpdf/config/lang/eng.php');
require_once('../tcpdf/tcpdf.php');
     
// get data from users table

mysql_select_db($database_process, $process);
$result = mysql_query("SELECT * FROM applicant WHERE applicantid = '4'");

while($row = mysql_fetch_array($result))
  {
    $appid = $row['applicantid'];
    $idcode = $row['idcode'];
    $type = $row['type'];
    $company = $row['company'];
    $email = $row['email'];
  }
   
// create new PDF document
$pdf = new TCPDF(PDF_PAGE_ORIENTATION, PDF_UNIT, PDF_PAGE_FORMAT, true, 'UTF-8', false); 

$pdf->SetPrintHeader(false); $pdf->SetPrintFooter(false);

// set default monospaced font
$pdf->SetDefaultMonospacedFont(PDF_FONT_MONOSPACED);

//set margins
$pdf->SetMargins(PDF_MARGIN_LEFT, PDF_MARGIN_TOP, PDF_MARGIN_RIGHT);

//set auto page breaks
$pdf->SetAutoPageBreak(TRUE, PDF_MARGIN_BOTTOM);

//set image scale factor
$pdf->setImageScale(PDF_IMAGE_SCALE_RATIO); 

//set some language-dependent strings
$pdf->setLanguageArray($l); 

// ---------------------------------------------------------

// set font
$pdf->SetFont('dejavusans', '', 10);

// add a page
$pdf->AddPage();
// create some HTML content
$txt = <<<EOD
Below are the details I require

Company type: $type
Company Name: $company
Company email: $email

EOD;


// output the HTML content
// $pdf->writeHTML($htmlcontent, true, 0, true, 0);
$pdf->Write(0, $txt, '', 0, 'L', true, 0, false, false, 0);

// $pdf->writeHTML($inlinecss, true, 0, true, 0);

// reset pointer to the last page
// $pdf->lastPage();

//Close and output PDF document
$pdf->Output('example_006.pdf', 'I');

//============================================================+
// END OF FILE

Hello,

I have a script that processes data from a form, and then outputs data from a MySQL table based on which selections are made on the form.

What I'm trying to do is create columns showing data for each month depending on which months the user selects, and then a "Total" column at the end of that. The output first determines the "family" the results are in, then the ID the product is for the parent family, and then it outputs the data based on what ID is listed.

Unfortunately, I have no idea how to do this without nesting while loops inside other while loops which I know is bad for server performance - and yes this does take a long time to complete.  Here is some of my code for this to show what I'm doing wrong:

Code: [Select]
$searchdatabase5 = "SELECT field3 FROM slssum2 WHERE company = '$companyname' AND CONCAT(year,month) BETWEEN '$startyear$startmonth' AND '$endyear$endmonth' AND field3 != 0 AND field4 != '995' GROUP BY field3";
$run5 = mysql_query($searchdatabase5) or die(mysql_error());
while($row5 = mysql_fetch_assoc($run5))
{
 $field5_3 = $row5['field3'];
 echo '<tr><td colspan="0"><hr style="width: 100%; height: 1px; color: #a0a0a0;"></td></tr><tr><td colspan="0" bgcolor="#ccffcc"><strong>FAMILY '. $field5_3 .'</strong><br /></td></tr>';
   $searchdatabase12 = "SELECT field4 FROM slssum2 WHERE company = '$companyname' AND CONCAT(year,month) BETWEEN '$startyear$startmonth' AND '$endyear$endmonth' AND field3 = '$field5_3' AND field4 != 0 GROUP BY field4";
   $run12 = mysql_query($searchdatabase12) or die(mysql_error());
   while($row12 = mysql_fetch_assoc($run12))
   {
    $field12_4 = $row12['field4'];
$searchdatabase6 = "SELECT field3,field4,field5,field6 FROM slssum2 WHERE company = '$companyname' AND CONCAT(year,month) BETWEEN '$startyear$startmonth' AND '$endyear$endmonth' AND field4 = '$field12_4' GROUP BY field3,field4,field5";
$run6 = mysql_query($searchdatabase6) or die(mysql_error());
while($row6 = mysql_fetch_assoc($run6))
{
$field6_3 = $row6['field3'];
$field6_4 = $row6['field4'];
$field6_5 = $row6['field5'];
$field6_6 = $row6['field6'];
echo '<tr><td colspan="0">'. $field6_5 .' - '. $field6_6 .'</td></tr><tr><td valign="middle" align="left" bgcolor="#ccc" width="183px">Units</td>';
$searchdatabase7 = "SELECT * FROM slssum2 WHERE company = '$companyname' AND CONCAT(year,month) BETWEEN '$startyear$startmonth' AND '$endyear$endmonth' AND field5 = '$field6_5' ORDER BY year,month ASC";
$run7 = mysql_query($searchdatabase7) or die(mysql_error());
while($row7 = mysql_fetch_assoc($run7))
{
$field7_3 = $row7['field3'];
$field7_4 = $row7['field4'];
$field7_5 = $row7['field5'];    
$field7_9 = $row7['field9'];
$field7_10 = $row7['field10'];
$field7_month = $row7['month'];
$field7_year = $row7['year'];
$startmonth2 = ltrim($startmonth, '0');
echo '<td bgcolor="#e6e6e6" width="95px" nowrap="nowrap" align="right">'; echo $field7_10; echo '</td>';
  }
Here is the output:



I know the code is very bad, but what would be the best way to recreate what I have in the image?

Thank you.

i have a mysql table which contains name like

mid           mname

101           AAA
102          BBB
103          CCC

now i have to print this name in a html table like AAA, BBB, CCC

i am getting this by while loop in a variable but when loop changes then value also change so please tell me how i get this only in one variable & print

I think this is the right section to post this is in.....

Anyway.....I'm building a web site  that requires i have  functionality to upload a tab delimited file (or some file format that is easiest) via php and insert the data into MYSQL. I've searched for many third party scripts but none seem to work. So I've decided to move to the community to see if someone can give me insight on how i might accomplish this script. I have some third party scripts but I'm not sure if they'd be of any use.

Thank you kindly

Hi, I'm trying to make a dynamic html table to contain the mysql data that is generated via php. I'm trying to display a user's friends in a table of two columns and however many rows, but can't seem to figure out what is needed to make this work.

Here's my code as it stands:
Code: [Select]
<?php
//Begin mysql query
$sql = "SELECT * FROM friends WHERE username = '{$_GET['username']}' AND status = 'Active' ORDER BY friends_with ASC";
$result = mysql_query($sql);
$count = mysql_num_rows($result);

$sql_2 = "SELECT * FROM friends WHERE friends_with = '{$_GET['username']}' AND status = 'Active' ORDER BY username ASC";
$result_2 = mysql_query($sql_2);
$count_2 = mysql_num_rows($result_2);

while ($row = mysql_fetch_array($result)) {
                                                          echo $row["friendswith"] . "<br>";
                                                }
while ($row_2 = mysql_fetch_array($result_2)) {
                                                          echo $row_2["username"] . "<br>";
                                                }
?>

The above simply outputs all records of a user's friends (their usernames) in alphabetical order. The question of how I'd generate a new row each time a certain amount of columns have been met, however, is beyond me. Anyone know of any helpful resources that may solve my problem? Thanks in advance =)

I am not sure if the title is correct; I tried my best. I'm a PHP/MySQL beginner and I really need some help. I have a small script that I am using for sending SMS. I recently added a phonebook. The problem with the phonebook right now is that it's available to all users, i.e. they can all update and delete all rows. What I would like to do is make it so that each user can update and delete only their own contacts. I have a table call contacts. Inside that table there is first name, last name, company and phonenumber. How can I accomplish this with PHP & MySQL?

CREATE TABLE IF NOT EXISTS `contacts` (
`contact_id` int(10) NOT NULL AUTO_INCREMENT,

`cell_no` text NOT NULL,
PRIMARY KEY (`contact_id`)
) ENGINE=InnoDB  DEFAULT CHARSET=latin1 AUTO_INCREMENT=8 ;

CREATE TABLE IF NOT EXISTS `users` (
`user_id` int(11) NOT NULL AUTO_INCREMENT,
`users_name` varchar(30) NOT NULL,
`uname` varchar(30) NOT NULL,
`u_pass` varchar(60) NOT NULL,
`utype` varchar(30) NOT NULL,
`timezone` varchar(30) NOT NULL,
`uapi_user` varchar(30) NOT NULL,
`uapi_pass` varchar(60) NOT NULL,
PRIMARY KEY (`user_id`)

<?php

    if($firstname == ''){

        exit;

        exit;

    }else{

        $result = mysql_query($query);

        $result = mysql_query($sql);
        confirm_query($result);

        </script>
    <?php
    }

        echo '<p><a href="new_contact.php" class="btn btn-success"> Back </a></p>';
        exit;

    }}
