Question

I have 2 mysql queries retrieved from my php class 2 different methods and they look as it follows

 SELECT
domains.id,  domains.name, domains.meta_title,
domains.meta_keywords,  domains.meta_description,
produkt_modul.keywords, produkt_modul.program_id,produkt_modul.title, produkt_modul.items, produkt_modul.search_type
 FROM domains
 JOIN produkt_modul ON domains.id = produkt_modul.domains_id WHERE domains.name='$domain_name' ORDER BY position

is fetching the rows for my product modules
and the second one

SELECT
domains.id, text_module.position, text_module.title, text_module.text
FROM    domains
JOIN    text_module
ON  domains.id = text_module.domains_id
WHERE   domains.name='$domain_name' AND active= 1 ORDER BY position

should give me the rows of the text modules.

When I generate the html output of the rows in my view I would like to order theme after the positions value.

what should look for example something like:

text_modul pos1
prod_modul pos2
prod_modul pos3
text_modul pos4

the actual view of the rows looks

text_modul1
text_modul4
prod_modul2
prod_modul3

How can I fetch the rows in such a way to have theme in the correct order.

Here’s how to do it in PHP. Note that this code assumes position is unique across both produkt_module and text_module results.

$allrows = array();
$res = mysql_query(/* your first query on produkt_module */);
while ($row = mysql_fetch_assoc($res) {
    $row['type'] = 'p';
    $allrows[$row['position']] = $row;
}

$res = mysql_query(/* your second query on text_module */);
while ($row = mysql_fetch_assoc($res) {
    $row['type'] = 't';
    $allrows[$row['position']] = $row;
}

ksort($allrows);  // sort all rows by position

foreach ($allrows as $pos => $row) {
    if ($row['type'] == 'p') {
        /* display a produkt_module row, i.e $row['title'], etc. */
    } elseif ($row['type'] == 't') {
        /* display a text_module row */
    }
}
