I'm trying to display a company name from a company table, and then loop out news from another table. The two tables are joined. This means that: I want to just pick out one row from one table in the join, and loop out data from the other table in the join. Is this possible? My code below only display two out of three posts in the news table in my loop.
Thanks!
$sql = "SELECT
newID, newTitle, newSummary, newDate,
comID, comName, comImageThumb
FROM
tblNews a RIGHT JOIN tblCompanies b
ON a.newCompanyID = b.comID
ORDER BY newDate DESC";
// Get company name and display
$companyData = mysql_fetch_assoc($result);
$comName = $companyData['comName'];
echo "<a href='#' class='name'>$comName</a>";
// Looping news
while($news = mysql_fetch_assoc($result)) {
// Display news posts
$newTitle = $news['newTitle'];
echo $newTitle;
}
Put everything inside while loop and try :
while($news = mysql_fetch_assoc($result)) {
// Get company name and display
$comName = $news ['comName'];
echo "<a href='#' class='name'>$comName</a>";
// Looping news
// Display news posts
$newTitle[] = $news['newTitle'];
echo $newTitle;
}
You should look at mysql GROUP_CONCAT for more detail.
Easiest solution probably would be to keep track of whether you are in the first iteration:
// query company name and news entries here
$firstRow = true;
while($news = mysql_fetch_assoc($result)) {
if ($firstRow) { echo $news['comName']; }
$firstRow = false;
echo $news['newTitle'];
}
You could also keep your current code and use mysql_data_seek(0) to reset the cursor after extracting the company name first.
And on a side note: Don't use mysql_* functions anymore! Use PDO instead.
Move the fetch operation to the end of the loop:
$companyData = mysql_fetch_assoc($result);
$comName = $companyData['comName'];
echo "<a href='#' class='name'>$comName</a>";
// you've already fetched a news item....
$news=$companyData;
do {
$newTitle = $news['newTitle'];
echo $newTitle;
} while ($news=mysql_fetch_assoc($result));

Can't believe this is giving me a problem but here it is. An example of the query and code is:
$sql = "SELECT
o.order_id, o.order_number, o.broker_id, o.agent_id
FROM orders o";
$sql_res = safe_query($sql);
/* I want to echo broker_id and angent_id only once here,
before the while loop, because the values are all the same */
while ($row = pg_fetch_array($sql_res)){
echo $order_number;
}
Assume broker and agent id numbers are each the same in every row. I don't want to echo them every time in the loop. I just want them to echo one time before the loop. Since they are the same, it does not matter which row they are echoed from.
I figured out a different way for a means to an end. It works well.
$sql = "SELECT
o.order_id, o.order_number, o.broker_id, o.agent_id
FROM orders o";
$sql_res = safe_query($sql);
$count = 0;
while ($row = pg_fetch_array($sql_res)){
if ($count == 0) {
echo $broker_id;
echo $agent_id;
}
echo $order_number;
$count += 1;
}
I realize I'm echoing the broker and agent IDs inside the while loop, but it's only an echo the first time through, and I can display them at top. And then every unique order is echoed. Visually, it accomplished what was needed for the end user.
Sorry for my English,
I need to display a banner ad from a database every third row in php. Banner ads and rows with the classified are selecting from database. To this moment I create something like this:
Rows with the classifieds from database:
while(#$row_select_kat = mysql_fetch_assoc($results_select_kat))
{
... //classifieds from database
if(($row_select_kat['id_ogloszenia']%3)==0)
{
$lim = 1;
echo"<div id=\"rek_poz_a\">";
modAddsDisplayHelper::wyswietlReklamyPozA();
echo"</div>";
}
}
Selecting banner ads from databes:
public static function wyswietlReklamyPozA()
{
$baza_danych = &JFactory::getDbo();
$query_sel_all_banners = "SELECT * FROM juxhv_banners";
$baza_danych->setQuery($query_sel_all_banners);
$baza_danych->query();
$banner_ads = $baza_danych->loadObjectList();
echo$query_sel_all_banners;
echo"Liczba x= ".$l_ogloszen;
foreach($banner_ads as $banner_ad)
{
if($banner_ad->state==1)
{
echo"$banner_ad->name<br/><img src=\"images/$banner_ad->username/bannerwerbung/$banner_ad->zdjecie\" width=\"434px\" height=\"94px\" />";
}
else
{
echo"No banner";
}
}
}
When I doing this in that way at every three rows displaying all three banner ads. How can I display only one banner ad every three rows?

Greetings
You need to use external counter variable which will be incremented on each iteration and depending on its condition you can check modulo condition: Please see the following updated code.
[code]
$recordCount = 0;
while(#$row_select_kat = mysql_fetch_assoc($results_select_kat))
{
if(($recordCount%3)==0)
{
echo"<div id=\"rek_poz_a\">";
modAddsDisplayHelper::wyswietlReklamyPozA();
echo"</div>";
}
$recordCount++;
}
if($banner_ad->state == 1) {
echo"$banner_ad->name<br/><img src=\"images/$banner_ad->username/bannerwerbung/$banner_ad->zdjecie\" width=\"434px\" height=\"94px\" />";
break;
}
In this way you only print one banner, but always will be the first with state == 1 in the database.
Maybe is better improve the query:
$query_sel_all_banners = "SELECT * FROM juxhv_banners WHERE state = 1 LIMIT 1";
That will give you the same result, I think.
I hope it helps
This is part of code from my backoffice page. ( is an edit.php page for a user to edit / modify )
// first query to get cats from user table
$query = "select * from user where name='".$_SESSION['username']."' order by id ASC limit 1";
$result=mysql_query($query);
if (mysql_num_rows($result)) {
while($row=mysql_fetch_array($result)){
$cat1 = $row['cat1'];
$cat2 = $row['cat2'];
$cat3 = $row['cat3'];
$cat4 = $row['cat4'];
$cat5 = $row['cat5'];
$cat6 = $row['cat6'];
$cat7 = $row['cat7'];
$cat8 = $row['cat8'];
$cat9 = $row['cat9'];
$cat10 = $row['cat10'];
}
}
// now i want to build 10 select boxes with selected according the user table $cats
// below is what i can build to first box $cat1
// is there a way i can produce this for the 10 select boxes whitout having to make 10 cycles of bellow code
<select name="theme" id="theme">
<?php
$q1 = 'SELECT * FROM cats ORDER BY title ASC';
$r1 = mysql_query($q1);
while( $row = mysql_fetch_array($r1)) {
if ( $cat1 == $row['id'] ) {
print "<option class=\"cssoption\" selected=\"selected\" value=\"".$row['id']."\">".htmlentities($row['title'])."</option>";
}
else {
print "<option class=\"cssoption\" value=\"".$row['id']."\">".htmlentities($row['title'])."</option>";
}
}
?>
</select>
I am not a coder so this might not be effective code.
Hope someone can help me here and understands what i am trying to do.
Many Thanks.
The code is fine. This 10 cycles as you name it is a almost zero cost.
This is the usual way we do it, we fetch sequentialy the records one by one.
In addition it makes no sense to ask not to do the 10 cycles because you are applying an if else condition in the same time, this means that you check every record if the cat id is the same with the row so you need the loop.
On the other hand if for some reason you want to skip some records, you can use the mysql seek function to start fetching from the desired record.
for($i=0;$i<99999;$i++)
(9999*9999);
echo 'This time the cost of this loop was:',(microtime()-$start),' seconds.';

I'm trying to create a dynamic list (5 row results) in php by first getting data from one table then using a resulting var to get the latest uploaded "image_links" (just 1 from each of the 5 artists) from another table -- then echo out.
The code here gives me the only one row with the latest image. When I comment out the "// get the latest image link uploaded ///" section of the code I get the 5 rows of different artists I really want but, of course, w/o images. I tried (among a bunch of things) mysql_result() w/o the while statement but that didn't work.
So what am I missing?
Thanks

If I read your code correctly, I see you looping using data from query1 in the control structure, and a lookup on query2 within each loop. You are reusing the variables in your loop1 control structure for query2 ($num and the query handle ($res)) for the second loop. Probably not desirable within the loop.
You're sharing the variables $num and $res between the two queries ... your original properties will be overwritten when the second query is run. Use different property names for the inner query.
Example of problem:
$result = QueryA();
while( $row = $result->getRow() )
{
// -- You're overwriting the original result here ...
$result = QueryB();
// Next time the loop runs, it will run using the result from QueryB();
}
So change ...
$res = mysql_query($QUERY2);
$num = mysql_num_rows($res);
if($num>0 )
{
while($row = mysql_fetch_assoc($res))
{
mysql_fetch_assoc($res);
$image_link= $row['image_link'];
}
to
$res2 = mysql_query($QUERY2);
$num2 = mysql_num_rows($res2);
if($num2 > 0)
{
while($row2 = mysql_fetch_assoc($res2))
{
$image_link= $row2['image_link'];
}
this is a mess - as others have said you're using the same variables for different purposes.
That you're storing integers which seem to represent enumerations in a char field is bad.
You're iterating through the second result set to find the last record (from an unsorted result set!).
You only need one query - not 2.
SELECT f.artist_name, f.artist_id, f.dateLastSent....
SUBSTR(
MAX(
CONCAT(DATE_FORMAT(date_submit, '%Y%m%d%H%i%s'), a.image_link)
), 15) as img_link
FROM followArtist f
LEFT JOIN artWork a
ON (a.artist_id=f.artist_id AND a.make_avail = '1')
WHERE user_id = $user_id
GROUP BY f.artist_name, f.artist_id, f.dateLastSent....
Here's what I've got so far-
$awards_sql_1 = mysql_query('SELECT * FROM categories WHERE section_id = 1') or die(mysql_error());
$awards_sql_2 = mysql_query('SELECT * FROM categories WHERE section_id = 2') or die(mysql_error());
$awards_sql_3 = mysql_query('SELECT * FROM categories WHERE section_id = 3') or die(mysql_error());
$awards_sql_4 = mysql_query('SELECT * FROM categories WHERE section_id = 4') or die(mysql_error());
$loop = 1;
while($row_sections = mysql_fetch_array($sections_query)) {
$category = 1;
echo "<h3>" . $row_sections['section_name'] . " (Loop# $loop)</h3>";
while($categories = mysql_fetch_array(${"awards_sql_{$loop}"})) {
${"winners_sql_{$loop}"} = mysql_query("SELECT * FROM 2009_RKR_bestof WHERE section = $loop && category = $category ORDER BY result_level ASC") or die(mysql_error());
echo "<h4><strong>{$categories['category_name']}</strong></h4>";
echo "<ul class=\"winners\">";
>> while($winners = mysql_fetch_array(${"winners_sql_{$loop}"})) {
switch ($winners['result_level']) {
case 1: $result_level = "Platinum"; break;
case 2: $result_level = "Gold"; break;
case 3: $result_level = "Silver"; break;
}
if (isset($winners['url'])) { $anchor = ""; $close = ""; }
echo "<li>$anchor{$winners['winner']}$close ($result_level)</li>";
unset($anchor);
unset($close);
}
echo "</ul>";
$category++;
}
$loop++;
}
Where I'm getting stumped, is I'm getting this thing to loop through correctly, my loop counter ($loop) is working, but when it gets time to spit out the actual reward recipients after the first loop through winners, it's only producing the category titles, the list-items are not getting looped out.
I added a little pointer to where I think the problem begins or centers around (>>).
My guess is I need to maybe unset a var somewhere, but I don't know, I can't see it.
I'm with KM - you're displaying a single page and with your loops, you've got a LOT of queries happening at once - what if 1,000 people hit that page at the same time? ouch...
Maybe consider a larger query (with some repeated data) and loop through it once?
For example:
SELECT
section_name,
category_name,
result_level,
url,
winner
FROM 2009_RKR_bestof
INNER JOIN categories ON 2009_RKR_bestof.category = categories.id
INNER JOIN sections ON 2009_RKR_bestof.section = sections.id
ORDER BY section_name,category_name ASC
In your loop, you can do checks to determine if you're in a new section (category/whatever):
//pseudo-code
$current_section = "";
while($stuff = mysql_fetch_array($sql))
{
if ($current_section == "")
{
$current_section = $stuff["section_name"];
}
if ($current_section == $stuff["section_name"])
{
//keep going in your loop
}
else
{
//we've gotten to a new section - so close your html and start a new section
}
}
You get the idea..
My guess would be that it is a data problem. It isn't having trouble reading the titles, only the winners. If it iterated once, I would check the data, and ensure that winners_sql_2 - winnders_sql_4 are getting actual data. Perhaps add an echo winners_sql_2 line, to output the contents of the query, and ensure the query is framed correctly.
