PHP - Mysql Select Limit X,y..dont Load Last 3 Rows

Hi guys I have a problem. I limit the displayed rows by 10 (which works) and then a link saying "next" or "previous"
The link itself works, but the site always just displays teh first 10 data entries.
What do I do wrong?
Thank you!

Code: [Select]

$password="****"; // Mysql password

$tbl_name="sp_users"; // Table name

// Connect to server and select database.
mysql_connect("$host", "$username", "$password")or die("cannot connect");
mysql_select_db("$db_name")or die("cannot select DB");

//$sql="SELECT * FROM $tbl_name ORDER BY user_id";
$sql="SELECT * from sp_users,sp_schools where sp_users.user_id=sp_schools.school_id ORDER BY school_name LIMIT 0, 10";
$result=mysql_query($sql);

<?PHP

  $startrow = 0;
//otherwise we take the value from the URL
} else {
  $startrow = (int)$_GET['startrow'];
}
?>
<?PHP
//this part goes after the checking of the $_GET var
$fetch = mysql_query("SELECT * FROM sp_users,sp_schools where sp_users.user_id=sp_schools.school_id LIMIT $startrow, 10")or

I am trying to include a dropdown menu on a page so that a user can choose how many records will be shown and return that data back to the same page. what I have so far is....

The Form
Code: [Select]
<form action="PHP_SELF" method="post" name="records_per_page" target="_self">
     Number of Records per page
     <select name="records_per_page" id="records_per_page">
       <option value="5">5</option>
       <option value="10">10</option>
       <option value="15">15</option>
       <option value="20">20</option>
       <option value="25">25</option>
       <option value="30">30</option>
       <option value="40">40</option>
       <option value="50">50</option>
   </select>
   </form>
The Query
// How many rows to show per page
$rowsPerPage = 25;

// Retrieve all the data from the seasons table
$result = mysql_query
("SELECT *, 
DATE_FORMAT(`season_start`,' %D %M %Y') AS startdate, 
DATE_FORMAT(`season_end`,'%D %M %Y') AS enddate 
FROM seasons 
LIMIT ";
 if ($_POST['records_per_page'] = '')
  $result .= "'$rowsPerPage' ");
else
$result .= "'$records_per_page' ");

or die(mysql_error());  


The error I get is
Code: [Select]
Parse error: syntax error, unexpected ';' in /homepages/46/d98455693/htdocs/content/test/seasonslist2.php on line 28which refers to the line
LIMIT ";

Having posted the code into Dreamweaver it also shows errors for the two options in the if statement
$result .= "'$rowsPerPage' ");

$result .= "'$records_per_page' ");
so it is clearly that I have set the code up incorrectly, probably with misplacement of ;'s.

What I am trying to do is when the page loads normally, the records should be limited to $rowsPerPage but if a user has specified a number of rows in the dropdown it should show that number. Once I have that sorted I will also be trying to implement a'Start from Record Number' option.

As always, any advice would be immensely appreciated!

Thanks in advance

Hi all,

I need your help as I have got a problem with display the 50 rows in the search results. I want to limit 50 rows in per page and if I have less than 50 rows like 21 rows in the page 2 then display the 21 rows.

I have got a problem with the limit, because when I tried to use `LIMIT 0, 50`, it will display total 71 rows which I only want to display no more than 50 in per page.

Here is what I have tried:

    $search_mailbox = $link->prepare("SELECT * FROM $folder WHERE from_email LIKE ? OR subject LIKE ? OR message LIKE ? ORDER BY received_date DESC LIMIT 0, 50");
    $search_mailbox->execute([$searchemail, $searchsubject, $searchmessage]);

And I have also tried this:

    $search_mailbox = $link->prepare("SELECT * FROM $folder WHERE from_email LIKE ? OR subject LIKE ? OR message LIKE ? ORDER BY received_date DESC LIMIT $offset, $limit");
    $search_mailbox->execute([$searchemail, $searchsubject, $searchmessage]);

It will not limit the rows I want. It will still show the 71 rows.

Here is the full code:

   

<?php
    
    // Initialize the session
    session_start();
    
    //Connect to the database
    require_once('config.php');
    
    $searchemail = '%' . 'gmail.com' . '%';
    $searchsubject = '%' . 'gmail.com' . '%';
    $searchmessage = '%' . 'gmail.com' . '%';
    
    $mailbox = $link->prepare("SHOW TABLES");
    $mailbox->execute();
    $folders = array();
    $total = 0;
    $total_rows = 0;
    $i = 0;
            
    while ($folder = $mailbox->fetch(PDO::FETCH_NUM)) {
        $folder = $folder[0];
    
        if (strpos($folder, 'users') !== false) {
            $folder = str_replace('users', '', $folder);
        }
        else
        {
            $folders[$i] = $folder;
        }
        $i++;
    }
    
    foreach($folders as $folder) {
        $search_mailbox = $link->prepare("SELECT * FROM $folder WHERE from_email LIKE ? OR subject LIKE ? OR message LIKE ? ORDER BY received_date DESC LIMIT 0, 50");
        $search_mailbox->execute([$searchemail, $searchsubject, $searchmessage]);
        
        if ($search_mailbox->rowCount() > 0) {
            $total += $search_mailbox->rowCount();
        }
    }
    
    $page = 1;
    $limit = 50;
    //$per_page = 50;
    //$pages = ceil($total / $per_page);
    
    $offset = ($page - 1) * $limit;
    
    
    foreach($folders as $folder) {
        
        $search_mailbox = $link->prepare("SELECT * FROM $folder WHERE from_email LIKE ? OR subject LIKE ? OR message LIKE ? ORDER BY received_date DESC LIMIT $offset, $limit);
        $search_mailbox->execute([$searchemail, $searchsubject, $searchmessage]);
    
    
        if ($search_mailbox->rowCount() > 0) {
            foreach($search_mailbox->fetchAll() as $k => $row) {
                $email_number = $row['id'];
                $search_from = $row['from_email'];
                $search_subject = $row['subject'];
                $total_rows++;
                echo $search_subject . '.........................' . $total_rows;
                echo "<br>";
            }
        }
                        
    }
    
    ?>

I am unable to fetch the first 50 rows in the page 1 and I am also unable to fetch the 21 rows in the page 2. 

What I am trying to achieve is when I am in page 1, I want to display the first 50 rows, then in the page 2 if I have another 50 rows then display the 50 rows, but if I have less than 50 rows like 21 rows then display the 21 rows.

Can you please show me an example how I can start with first 50 rows when I am in the page 1 then in page 2 display 21 rows to make in total 71 rows?

Any advice would be much appreicated.

Thanks in advance.

what Im basically trying to do is just like a phpmyadmin function... you select rows you want to update with a checkbox and then it takes you to a page where the rows that are clicked are shown in forms so that you can view and edit info in them... and then have 1 submit button to update them all at once.

I have got a set of data for a country for each week of the year, but want to display the data a quarter at a time, using a form which posts a value into LIMIT, which was OK for the 1st quarter, but for subsequent quarters I needed to use LIMIT in the form LIMIT start, rows. I found by experiment that this had to be the last statement in the query. when I added the start I got an error: Parse error: syntax error, unexpected ',' in /homepages/43/d344817611/htdocs/Admin/Visitdata.php on line 10 Here is the SQL part of my code:

$Visit_data="SELECT WeekNo.WNo, WeekNo.WCom, Countries.Country, ctryvisits.CVisits FROM ctryvisits 
LEFT JOIN Countries
ON ctryvisits.country=Countries.CID
LEFT JOIN WeekNo
      ON ctryvisits.WNo=WeekNo.WNo
      WHERE Countries.Country = '".$_POST["Country"]."'
ORDER BY ctryvisits.WNo LIMIT '".$_POST["QUARTER"]."'" - 13, '".$_POST["QUARTER"]."'";

Is this the best way of doing what I require or is there an easier way of achieving what I want?

I have searched for a solution to a code that I wrote, with unique numbers in the SQL statement of LIMIT at the end and using execute().  I have also set

PDO::ATTR_EMULATE_PREPARES, false

I know that there is ways to use bindValue() or bindParam() instead of execute() for this. However, the way I have it set up works, but is there a security flaw with the way I am using LIMIT and should I be using bindParam() instead of execute()?

<?php
if ($numbered_row == 0) {
	$limitation = '';
} else {
	$started_page = ($page_number - 1) * $items_on_each_page;
	$limitation = ' LIMIT '. $started_page . ',' . $items_on_each_page;
}
$sql_query = "SELECT * FROM `myTable` WHERE `id` = :id AND `group` = :group AND `name` LIKE :name AND `country` = :country ORDER BY `date` DESC" . $limitation;
$query_result = $pdo_connecting->prepare($sql_query);
$query_result->execute(array(':id' => '73', ':group' => 'Furniture', ':name' => '%'.$name.'%', ':country' => $country));
?>

When I run this code it takes longer then I want to load the search results. I thought by only loading the first 30 rows it catches it would speed things up. Any ideas? I changed the $db to be 30, but only my first page painted and it was not much faster....

Code: [Select]
if(!empty($keyword) && $keyword!='Zip Code')
$sql="SELECT profiles.*,zipCode FROM profiles LEFT JOIN area_served  ON area_served.profileId = profiles.profileId WHERE profileType!='HO' AND

profiles.status='Y' $qrystr GROUP BY profiles.profileId $orderby CASE zipCode  $zips_order_str , companyName asc ";
else
$sql="SELECT * FROM profiles LEFT JOIN area_served  ON area_served.profileId = profiles.profileId WHERE profileType!='HO' and status='Y' $qrystr

GROUP BY profiles.profileId $orderby ";

//echo  $sql;

$db->query($sql);
$numRows=$db->numRows();
$page->set_page_data($_SERVER[PHP_SELF],$numRows,$listing,10,true,false,true);
$page->set_qry_string("searchFor=$searchFor&cat=$cat&state=$state&keyword=$keyword&distance=$distance&sorting=$sorting&listing=$listing");
$res=$db->query($page->get_limit_query($sql));
$smarty->assign('numResult',$numRows); /* show pagination */



while($row=$db->fetchAssoc($res))
{
if($row['thumbnailPhoto']=='personalPhoto' || $row['thumbnailPhoto']==''){
if(!empty($row['personalPhoto'])){
$personalPhoto="profiles/".$row['personalPhoto'];
$rimg->setImage($personalPhoto);
$row['personalPhoto']=$rimg->resize(75,75,substr($personalPhoto,0,strpos($personalPhoto,"."))."_search");
}else{
$row['personalPhoto']="images/my-photo.gif";
}
}else{
if(!empty($row['logo'])){
$personalPhoto="profiles/".$row['logo'];
$rimg->setImage($personalPhoto);
$row['personalPhoto']=$rimg->resize(75,75,substr($personalPhoto,0,strpos($personalPhoto,"."))."_search");
}else{
$row['personalPhoto']="images/my-photo.gif";
}
}
if(count($cat>0)){
$row['cat']=@implode(", ",$cat);
}

if(strlen($row['companyInfo'])>90){
$concat="...";
}
else{
$concat="";
}

Hi,

my page is currently up at brewhas.org/transactions.php.  When I retrieve a set of results > the defined # per page (such as entering 'WI' for last name), I see the first page correctly, and see the links to next pages, but when I go to the next page there are no results displayed.  Same for p.3, etc.

So I've looked around enough to know that I need to pass a variable to the subsequent pages, either via a session variable or the URL.  I have 2 fields input on the form, as well as a limit and offset.  My questions are 1) do I need to pass all 4 and if so then should I use a session variable so the URL does not get too long, and 2) can anyone provide any help with setting session variables and including them to be passed?

I'm a newbie and have grabbed some code where I can but this is where i'm stuck.  thanks in advance.

hello, im only getting the second half of my results showing in my dropdown box.  here is my code.

Code: [Select]
if(isset($_GET['id']))
{
$uid = $_GET['id'];
}

$forward = mysql_query("SELECT * FROM players WHERE status = '1' AND position = 'forward' ORDER BY name");
$forward1="";
while($row1 = mysql_fetch_array($forward))
  {
$forwardid=$row1["id"];
$forwardname=$row1["name"];
$forwardteam=$row1["team"];
$forward1.="<OPTION TITLE=\"$forwardteam\" VALUE=\"$forwardid\">".$forwardname.'</option>';
  }

$result = mysql_query("SELECT * FROM picks WHERE uid = '$uid' AND pickid = 'forward1'");
while($row = mysql_fetch_array($result))
{
  $playerid=$row['playerid'];
}

if(isset($forwardpick1)) {
$result1 = mysql_query("SELECT * FROM players WHERE id = '$playerid'");
while($row1 = mysql_fetch_array($result1))
{
  $forwardpick1=$row1['name'];   
}
$forwardpick1="<br /><br /><font color ='#000000' size = '5'><b>$forwardpick1";
} else {
$forwardpick1="
<form method='POST' action='draftpick.php' name='forward1'>
<p><font color='#000000'><select size='1' name='player'>
<?php echo '$forward1'; ?>
</select><br><br><input type='submit' value='Submit' name='submit'></font></p>
</form>
";
}
any direction is appreciated.

How can I limit the amount of time my while loop to only show the first 4 rows of my SQL table?   I am using this code to loop my whole table:  

while($row = $results->fetch(PDO::FETCH_ASSOC))
                        {
                        echo '
                        <li>Mileage: '.number_format($row["Mileage"]).'</li>
                        <li>Engine size: '.$row["EngineSize"].'cc</li>
                        ';} ?>

I only want to loop through the first 4 rows of my SQL table, I then want to duplicate the same code but start at the 5th row until the 8th row of the table, how can I do this?   Thanks, Nick

Hello, i am trying to get my form to list usernames ascending as an option, but the select field just returns blank.

Here is my code:

}
}

              <form action="/" method="post">

                <div class="column">

                    <select name="user" id="user" placeholder="Select A User To Edit" class="{validate:{required:true}}">
                      <option>Select A User To Edit</option>
                      <? editUserForm(); ?>
                    </select>
                  </p>

Thanks,

 $result = mysql_query("SELECT *  FROM `friend_system` WHERE `friend_system_accepter` = '$myusername' ");
echo mysql_num_rows($result);

This displays the total rows in the table.

$result = mysql_query("SELECT COUNT(friend_system_accepter)  FROM `friend_system` WHERE `friend_system_accepter` = '$myusername' ");
echo mysql_num_rows($result);

This displays '1', which is incorrect.   I want to echo out the number of rows where 'friend_system_accepter' = $myusername   Thanks

Hi. I'm trying to make a sort of a forum, and this is the part of the code that needs to be changed, only I don't know how.
Code: [Select]
mysql_connect("$host", "$username", "$password")or die("cannot connect");
mysql_select_db("$db_name")or die("cannot select DB");
$sql="SELECT * FROM $tbl_name ORDER BY id DESC";
// OREDER BY id DESC is order result by descending
$result=mysql_query($sql);
?>
<table width='50%' border="0" align="center" cellpadding="3" cellspacing="1">
<?php
$limit=10;
$page=0;
$numrows = mysql_num_rows($result);
$pages = intval($numrows/$limit);
if ($numrows % $limit) {
$pages++;}
$current = ($page/$limit) + 1;
if (($pages < 1) || ($pages == 0)) {
$total = 1;}
else {
$total = $pages;}
$result = mysql_query("SELECT * FROM $tbl_name ORDER BY id DESC LIMIT $page,$limit");

I made a database with 4 fields and 11 entries. The script shows the last 10 entries just as it should, but when I click on the 'next' button, nothing happens (it should show the first entry, but it just refreshes the page, and still the last 10 entries/1st page are shown). I think it has something to do with the link, but I can't figure out what exactly.
Can someone help, or at least give me a hint? Thanks in advance. Bye.

I feel like a tard for having to ask this, but I've spent way too much time trying to figure this out, so i've brought it to you guys.

I have run into a an error running a while loop off a query:

$rowcount= mysql_query("SELECT COUNT(*) FROM `shoutbox`");
$count = mysql_fetch_array($rowcount);
$count = $count['COUNT(*)'];
$said = mysql_query("SELECT * FROM shoutbox ORDER BY date ASC LIMIT ('$count' - 5),'$count' ");

while($row = mysql_fetch_array( $said )){  //line 14 in the code

echo $row['shouter'].':  '.$row['contents'].'<br />'; 

}


Code: [Select]
mysql_fetch_array(): supplied argument is not a valid MySQL result resource in /home/mahngiel/public_html/shout.php on line 14This script works when I remove the limit counts, but then I have to descend the order and things are not in the position I want them in.  I'm sure the problem is the limit vars, but dunno which way to go to fix it. thanks
