PHP - How To Check If Duplicate Rows Across Multiple Columns

Alright,
I need to find a way to display the top ten duplicated rows for a table in my database. I have tried multiple methods but I have failed. Can you please assist me with this problem. I currently run a query in phpmyadmin to get the result, but i cant figure out how to properly code the php script.

Hola Everybody !!

I'm putting together a web app similar to Digg and was wondering if there is a function or code example I can use to avoid users submitt the same url.

For example:
Right now the user can submit;
1. http://www.example.com?post01
2. http://example.com?post01
3. www.example.com?post01

I want the web app to check if the link has been submitted by the user first and look for duplicate submission.

Any ideas ?

Thank you,

V.

Hi,

having stopped php for a while, i'm a little rusty, can someone help me - instead of the results returning in a row by row format, can i have it so it returns column by column?
so, rather than result 1 being first, then 2 underneath then 3 etc etc, can i have result 2 next to result 1?

heres my code

$result = mysql_query("SELECT * FROM members ORDER BY member_id DESC")   
or die(mysql_error());  

echo "<table border='2'>";
echo "<tr> <th></th> <th></th> <th></th> </tr>";
// keeps getting the next row until there are no more to get
while($row = mysql_fetch_array( $result )) {
// Print out the contents of each row into a table
echo "<tr><td>"; 
echo $row[printf('<img src="%s" height="96" width="128" style="border: 0" />', $row['profile_pic_short'])];
echo "</td><td>"; 
echo "<a href=\"PHP-Login/advert_pages/view_profile_specific.php?seller_name=$row[login]\">". $row['login'] . "</a>";
echo "</td></tr>"; 

} 

echo "</table>";
?>


all help appreciated

thanks

Hello,

i've got this code, to insert some form data into my db, it checks for a value if it exists already, it won't insert, now i want to add another value to check, but i don't know how.

This is my code:

Code: [Select]
<?php
if(isset($_POST['submit'])){
   if (strlen($_POST['code']) == 12 && substr($_POST['code'],0,6) == '610147'){
      $code = $_POST['code'];
      $select_query = mysql_query("SELECT * FROM jupiter WHERE code = '$code'");
      if(mysql_num_rows($select_query) == 0){
         $remote_addr = $_SERVER['REMOTE_ADDR'];
         $secret = $_POST['euro'];
         mysql_query("INSERT INTO jupiter(code,euro,ip,date,used) VALUES('$code','$secret','$remote_addr',CURDATE(),'n')");
 
      }
  Print "<font color='green'>OK</font>"; 
} else { 
    
Print "<font color='red'>Error</font>"; 
}
   
}?>
This checks if "code" already exists, now i want to also have it check for "ip"

Can someone help me out here please.

Thanks !

Hello,

i am inserting some form data into my mysql db, i happen to get some duplicates so i want to check first if the entry exists already before i insert.

my current code:

Code: [Select]
<?php

if(isset($_POST['submit']))  { ?>
<?php 
if (strlen($_POST['code']) == 19 && substr($_POST['code'],0,7) == '5541258')  { 
     mysql_query("INSERT INTO table(code,secret,ip,date) VALUES('$_POST[code]','$_POST[secret]','$_SERVER[REMOTE_ADDR]',CURDATE())");
Print "<font color='green'>The code will be checked now</font>"; 
} else { 
    
Print "<font color='red'>The code is invalid</font>"; 
}
?><?php } ?>
I would like to use the value 'code' to check if the entry exists, that one is unique for each entry. How would i do that ?

Thanks !

Hello,

I have looked on the forum, but haven't found the answer to this.

I have a basic [name, email, phone, event] web form and want to make sure there person is not submitting twice by doing duplicate check of the mail.  I looked at other solutions that suggested setting up unique IDs for each user, but it would be possible for a user to sign up for more then one event.

Any info would be helpful. Not a newbie, but not an expert.

I'm working on a directory component and have kind of a tricky thing I need to do.

The list of results pop through ajax on the left side along with it's google map number tag, and the google map pops on the right side. To make it even trickier the results are popped through a radius search by proximity.

The problem is if there are multiple results with the same address you end up having all of the number tags on the map buried under the last tag with that address, plus it makes for kind of a long list.

What I need to do is run a check to see if the previous result is the same address, and if yes not pop that result in a new table cell, rather stick it in a jquery drop down div so that all of the following results with the same address are stuffed in the jquery drop down in the same table cell under the first result with that address.

In a perfect world all of the listings with the same addresses would be submitted in order so I could just do a check for the previous itemid's address, but of course that's not the case. I thought about running a query to grab ALL of the addresses and then check the item's address against it to see if it matches and if yes echo the jquery div instead of the <td>, but obviously that won't work because that will cause the first item with that address to be put in the div also. Plus I don't know if that's a very efficient way to go about it anyway.

Here's kind of the basic thing I'm working with:
Code: [Select]
$query = "SELECT data_txt FROM jos_sobi2_fields_data WHERE fieldid = 76 AND itemid = $mySobi->id";
$result = mysql_query($query) or die(mysql_error());
while($row = mysql_fetch_array($result)){
$myaddress = $row['data_txt'];
}
echo "<td $style>";

Any ideas?

Hello all,

   I am trying to learn OOP in PHP so please forgive my ignorance. I seem to be having difficulty inserting data into my database from checkbox items. My database has a column for each each fruit. I would like for each column to be populated with either a one(1) for checked or a zero(0)  for not checked. Currently, my attempts have failed. I can either get all checkboxes to insert all zeros or I can get the first column to insert a one(1) while the others as zeros. Is there anybody here that can help me figure out what I am doing wrong and help me to re-work my code so I can get this to work? If anybody can help me using OOP methods that would be fantastic. Thank you all in advance.

 

$preffruit->create_preffruit(array(

  'fruit_apple' => escape(Input::get(['fruit_selection'][0]) ? 1 : 0),
  'fruit_orange' => escape(Input::get(['fruit_selection'][1]) ? 1 : 0),
  'fruit_banana' => escape(Input::get(['fruit_selection'][2]) ? 1 : 0),
  'fruit_pear' => escape(Input::get(['fruit_selection'][3]) ? 1 : 0),
  'fruit_kiwi' => escape(Input::get(['fruit_selection'][4]) ? 1 : 0)

  ));

i'm trying to echo out the results from a query onto a page, but rather than having them echo out as rows in a table, i want them to be displayed in columns, i.e. first column would have the first 10 results and the second column would have the next to. Any ideas on how i could do this?

at the moment i'm using this code to display my results

$read=mysql_query("SELECT * FROM entry WHERE category_id=".$id." ORDER BY entry_title") or die("query failed".mysql_error());
$result=mysql_num_rows($read);
for($j = 0; $j < $result; $j++) { 
   

$row = mysql_fetch_array($read);

echo "<a href=article.php?id=".$row['entry_id']. ">".$row['entry_title']."</a><br />";
}

but this just displays it as a list down the middle

thanks

Ok I'm trying to insert multiple rows by using a while loop but having problems. At the same time, need to open a new mysql connection while running the insert query, close it then open the previous mysql connection.

I managed to insert multiple queries before using a loop, but for this time, the loop does not work? 
I think it is because I am opening another connection... yh that would make sense actually?

Here is the code:


$users = safe_query("SELECT * FROM ".PREFIX."user");
       while($dp=mysql_fetch_array($users)) { 
          
   $username = $dp['username'];
 $nickname = $dp['nickname'];
 $pwd1 = $dp['password']; 
 $mail = $dp['email'];
 $ip_add = $dp['ip'];
 $wsID = $dp['userID'];
 $registerdate = $dp['registerdate'];
 $birthday = $dp['birthday'];
 $avatar = $dp['avatar'];
 $icq = $dp['icq']; 
 $hp = $dp['homepage'];
 
echo $username." = 1 username only? :(";
      

// ----- Forum Bridge user insert -----

$result = safe_query("SELECT * FROM `".PREFIX."forum`");
$ds=mysql_fetch_array($result);
$forum_prefix = $ds['prefix'];
define(PREFIX_FORUM, $forum_prefix);
define(FORUMREG_DEBUG, 0);

$con = mysql_connect($ds['host'], $ds['user'], $ds['password']) or system_error('ERROR: Can not connect to MySQL-Server');
$condb = mysql_select_db($ds['db'], $con) or system_error('ERROR: Can not connect to database "'.$ds['db'].'"');
                
include('../_phpbb_func.php');
$phpbbpass = phpbb_hash($pwd1);
$phpbbmailhash = phpbb_email_hash($mail);
$phpbbsalt = unique_id();

safe_query("INSERT INTO `".PREFIX_FORUM."users` (`username`, `username_clean`, `user_password`, `user_pass_convert`, `user_email`, `user_email_hash`, `group_id`, `user_type`, `user_regdate`, `user_passchg`, `user_lastvisit`, `user_lastmark`, `user_new`, `user_options`, `user_form_salt`, `user_ip`, `wsID`, `user_birthday`, `user_avatar`, `user_icq`, `user_website`) VALUES ('$username', '$username', '$phpbbpass', '0', '$mail', '$phpbbmailhash', '2', '0', '$registerdate', '$registerdate', '$registerdate', '$registerdate', '1', '230271', '$phpbbsalt', '$ip_add', '$wsID', '$birthday', '$avatar', '$icq', '$hp')");
if (FORUMREG_DEBUG == '1') {
echo "<p><b>-- DEBUG -- : User added: ".mysql_affected_rows($con)."<br />";
       echo "<br />-- DEBUG -- : Query used: ".end($_mysql_querys)."</b></p><br />";
      
       $result = safe_query("SELECT user_id from ".PREFIX_FORUM."users WHERE username = '$username'");
       $phpbbid = mysql_fetch_row($result);
safe_query("INSERT INTO `".PREFIX_FORUM."user_group` (`group_id`, `user_id`, `group_leader`, `user_pending`) VALUES ('2', '$phpbbid[0]', '0', '0')");
safe_query("INSERT INTO `".PREFIX_FORUM."user_group` (`group_id`, `user_id`, `group_leader`, `user_pending`) VALUES ('7', '$phpbbid[0]', '0', '0')");
mysql_close($con);
}

         include('../_mysql.php');        
         mysql_connect($host, $user, $pwd) or system_error('ERROR: Can not connect to MySQL-Server');
mysql_select_db($db) or system_error('ERROR: Can not connect to database "'.$db.'"');
       
       }



So I need to be able to insert these rows using the while loop.. how can I do this?

I really appreciate any help.

Hello all! I'm having some issues with a snippet that I found online and have edited to how I want it.

Basically the code works at the moment, except if I were to search for 2 or 3 terms, it would search the columns username/action/result/changes for any result that have any of the words rather than results that include both terms, instead of either.

I want the query to be like (assuming 2 search terms):

Quote

username LIKE '%$filter%' OR action LIKE '%$filter%' OR result LIKE '%$filter%' OR changes LIKE '%$filter%' AND username LIKE '%$filter%' OR action LIKE '%$filter%' OR result LIKE '%$filter%' OR changes LIKE '%$filter%'


and not:

Quote

username LIKE '%$filter%' OR action LIKE '%$filter%' OR result LIKE '%$filter%' OR changes LIKE '%$filter%' OR username LIKE '%$filter%' OR action LIKE '%$filter%' OR result LIKE '%$filter%' OR changes LIKE '%$filter%'


It needs an AND instead of an OR, but I'm not sure how to go around doing it.

Here's the code as it is at the moment:

$filter = ($_POST['filter']); 

$query = "SELECT * FROM activity WHERE"; 

$searchresult = explode(" ", $filter); 

     foreach ($searchresult as $key => $filter) { 
$query .= " username LIKE '%$filter%' OR action LIKE '%$filter%' OR result LIKE '%$filter%' OR changes LIKE '%$filter%'"; 
     if ($key != (sizeof($searchresult) - 1))   
$query .= " AND ";
     }
$query .= "ORDER BY id DESC"; 

Sorry if this is a little confusing to understand, hope someone understands what I need.

hello, all:

I'm a newbie, and been trying to work out a way so that the results from an array (or mysql recordset for that matter), are nicely aranged in a table. I want them to show in a grid-like manner, with rows and columns added according to number of "items".

I worked out this small code snippet, with a sample array, and for the life of me, cant figure out how to make it so it automatically "breaks" columns at 5 and start new row. I got it to show me right number of rows, but then it repeats all 10 names within them, as opposed to just showing 5 names in each row...

Appreciate the help...

Code: [Select]
<?php
$names = array('Charles','Henry','Manny','Philip','Rose','Evelyn','Peter','Julia','Cary','Sophia');
$numberColumns = 5;
$numberNames = count($names);
$numberRows = ceil($numberNames / $numberColumns);

echo "<table border='1' width='400' cellspacing='0' cellpadding='0'>";

for ($i=1; $i<=$numberRows; $i++)
{ 
echo "<tr>";
foreach ($names as $name)
{
echo "<td>" . $name . "</td>";
}
echo "</tr>"; 
}

echo "</table>";
?>

Hi guys, is there anyway to process this $result from a mysql query inside PHP so that the data below will be formatted to a pivot-like table? The number of rows and columns of the output 'table' will be indefinite. Thanks so much!

Data:
ID   Row   Col   Name
1   1   A   A1
2   2   A   A2
3   3   A   A3
4   1   B   B1
5   2   B   B2
6   3   B   B3
7   1   C   C1
8   2   C   C2
9   3   C   C3


Results:
A1(1)   A2(2)   A3(3)
B1(4)   B2(5)   B3(6)
C1(7)   C2(   C3(9)

First of all excuse me if this topic is inappropriate in this forum. But I think it's rather a PHP problem.

I can't figure out multiple duplicate database records on submitting a form.

The database table have two columns:  the first one 'Id' with AUTO_INCREMENT and the second one 'Name'.

Here's the php code for database insertion and the form:
------------------------------------------------------------------

<?php

if($_GET['add_name']){
    $host = *******;
    $user = *******';
    $pass = *******;
    $db = *******;
    $con = mysql_connect($host,$user,$pass) or die;
    mysql_select_db($db,$con);
   
    $name = $_GET['add_name'];
    $sql = "INSERT INTO names (Name) VALUES ('$name')";
    mysql_query($sql);
}

?>

<form action="<?php echo $_SERVER['PHP_SELF'] ?>" method="GET">
Your Name:
<input name="add_name" type="text"  />
<input type="submit" value="Submit" />
</form>

------------------------------------------------------------------

After submitting the form to itself once I have multiple Name entries with different Ids. The curious thing is that with Chrome browser
I get two duplicate records, with Mozilla - three of them.
Seems like mysql_query runs multiple times.

It works fine when submitting the form to a separate script and not to itself.

Do I miss something? It must be very basic.
