Mysql / php query question. - GoFuckYourself.com

I'm collecting data from 3 tables, of which one of the tables (social_meminfo) has multiple rows for results. How can I isolate the results of social_meminfo identifying each rows results? Or should I use two separate queries? At there should be at least two rows that would be found. Also instead of using `$en['m'.$key]` I want to use `$en['b'.$key]`

Code:

        $res = mysql_query("SELECT *, DATE_FORMAT(sm.m_lld,'%m/%d/%y') 
                            AS m_lld_formatted 
                            FROM social_members sm
                            JOIN social_meminfo smi ON (sm.m_id = smi.m_id)
                            LEFT OUTER JOIN social_memtext smt ON (sm.m_id = smt.m_id)
                            WHERE sm.m_user = '".mysql_real_escape_string($en['user'])."'");            
        if (mysql_num_rows($res) == 0) call404();
    #while ($line = mysql_fetch_assoc($res)) {
        $line = mysql_fetch_assoc($res);
        foreach ($line as $key => $value) {
                $en['m'.$key] = str_replace("\n",'<br/>',stripslashes($value));
                }

or should I just use two queries and a while statement?

I believe you want to use the SELECT DISTINCT() and the GROUP BY clause.

I decided to split the query... using the code below how can I get each row plus field result? (i.e. $line['m_pos'][0] or something like that. which would be fieldname and row result 1)

Code:

$bio = mysql_query("SELECT * FROM social_meminfo 
            WHERE m_id = '".mysql_real_escape_string($en['mm_id'])."'");
                             
if (mysql_num_rows($bio) == 0) call404();
while ($line = mysql_fetch_assoc($bio)) {
foreach ($line as $key => $value) {
        $en['b'.$key] = str_replace("\n",'<br/>',stripslashes($value));
        }
echo '<pre>'; 
    print_r($line);
echo '</pre>';
}

Best for rapid development is to use custom query functions like this

Code:

	function fetchAll($query = false, $key = false) {
		$fetch = false;

		if($query) {
			if($result = mQuery($query)) {
	    		while($res = mysql_fetch_assoc($result)) {

	    			if($key && $res[$key]) {
	    				$fetch[$res[$key]] = $res;
	    			} else {
	    				$fetch[] = $res;
	    			}
	    		}
	    	}
	    }

	    return $fetch;
	}

and than you can tune it all, you will not have your code doubled

	    	}
	    }

	    return $fetch;

still running into the problem of not being able to separate the data by the outputting rows. everytime it does a loop it grabs another row or data. but I can't figure out how to designate a specific id or var for each row+field. if I have 5 rows of data I want to be able to say echo row:2 field: m_pos ... show data

All that code gives me a headache, I am a relative novice at this stuff.

I know you are trying to refine and use best coding practice and all that stuff, but unless this is a job for someone else or for a site with MASSIVE traffic why worry so much?

Use 2 or more queries - any modern server could handle it...

I decided to just go with two queries in post #4 but I'm running into the problem of not knowing how to separate the outputting data by rows. I need to do something like $line['m_pos'][0] where 0 means row one. That way I can properly place the data where it needs be. As of right now $line['FIELD'] doesn't let me know when row it came from

explain...? I personally am not a big fan of joins cause they can slow a system down if used to much.

decided to go with two queries and solved my row issue with an increment. so everything is working.

Code:

$bio = mysql_query("SELECT * FROM social_meminfo 
            WHERE m_id = '".mysql_real_escape_string($en['mm_id'])."'");
$i = 1;
if (mysql_num_rows($bio) == 0) call404();
    while ($line = mysql_fetch_assoc($bio)) { 
        foreach ($line as $key => $value) {
        $en['b'.$key . $i] = str_replace("\n",'<br/>',stripslashes($value));
        }
    $i++;        
    }
