Repeating the same query

I am doing a query where the choices are title=$extra1 or title=$extra2 or title=$extra3 (up to 6 extras)

I am getting the same result for all, and I ended up doing the below 6 times.

Surely there must be another way to do this to avoid the 6 queries?

PHP Code:


		
			
 $extra1songsquery = $DB_site->query("SELECT songid, title, url FROM soundtracks WHERE title='$extra1' AND 
active=1");
while($extra1songrow = $DB_site->fetch_array($extra1songsquery)) 
        {    
         $clip1=$extra1songrow['title'];
    $clip1id=$extra1songrow['songid'];
    $clip1url=$extra1songrow['url'];
    $extra1="<a href=\"showproduct.php?product=$product&do=main&mysong=$clip1id\">$clip1</a>"; 
        } 
 
$extra2songsquery = $DB_site->query("SELECT songid, title, url FROM soundtracks WHERE title='$extra2' AND 
active=1");
while($extra2songrow = $DB_site->fetch_array($extra2songsquery)) 
        {    
         $clip2=$extra2songrow['title'];
    $clip2id=$extra2songrow['songid'];
    $clip2url=$extra2songrow['url'];
    $extra2="<a href=\"showproduct.php?product=$product&do=main&mysong=$clip2id\">$clip2</a>"; 
        }

PHP Code:


		
			
$DB_site->query("SELECT songid, title, url FROM soundtracks WHERE title IN ('$extra1', '$extra2', '$extra3') AND active=1");

Can't you do a:

SELECT * FROM

That does not return the other items (url and songid).
This is a non Vb script where I cannot do a normal eval for a templatebit.
when I do:

PHP Code:


		
			
 $extra1songsquery = $DB_site->query("SELECT songid, title, url FROM soundtracks WHERE WHERE title IN ('$extra1', '$extra2', '$extra3') AND active=1");
 
while($extra1songrow = $DB_site->fetch_array($extra1songsquery)) 
        {    
         $clip1=$extra1songrow['title'];
    $clip1id=$extra1songrow['songid'];
    $clip1url=$extra1songrow['url'];
    $extra1="<a href=\"showproduct.php?product=$product&do=main&mysong=$clip1id\">$clip1</a>"; 
        }

and put in template:

$extra1

only the first one is returned. The others have no results.

I dont seem to understand your problem :)

Please post a scheme of your Table with example Data, the values for extra1, extra2, etc. and what you would like to have returned.

But I think your problem does have nothing to do with the query:

PHP Code:


		
			
$extra1.="<a href=\"showproduct.php?product=$product&do=main&mysong=$clip1id\">$clip1</a>";

OK, here is what I am doing:

When I input the data in that page

I have $desc which I am using to parse Geek autolink to lyrics.
I have 6 extra fields that I could use. I am using them to query a database of MP3s. I put the exact title in the various extra fields. Then I do a query in the php. If the soundtracks title matches one of the extras, then I need to get the info for each one of the extras (I have embeded a player in the page and when you click on the link at the bottom of the page, it plays the selected clip). My method works, but I have to do the same query six times.

The linked page is in french and I understand nothing :)

Please, just post your table scheme, example data, the extraX values and which rows you want to have selected for those.

Oh well, sorry for the French.

I am no guru. What you saw is from painfully put together hours of trial and error spaghetti codes. I don't even know what you mean by schema.

schema=scheme?

This is the scheme of Table datastore:

Code:

CREATE TABLE `datastore` (

  `title` varchar(15) NOT NULL default '',

  `data` mediumtext  NOT NULL,

  PRIMARY KEY  (`title`)

);

And this is example Data for this Table:

Code:

INSERT INTO `datastore` VALUES ('cron', '1122540900');

INSERT INTO `datastore` VALUES ('banemail', '');

Or in other words: A (part) dump of the Table.

ok thanks. I am putting only a few, because I have hundreds of data

PHP Code:

        }

how I am displaying it now:

Quote:

<span class="smallfont">$extra1$extra2$extra3$extra4$ext ra5$extra6</span>

and the result attached (I have 2 now, still testing)

Thanks.

OK. Now if you could also post example Values for extra1, etc. and what should be the output then, I might be able to help you ;)

Values for extras are exactly the same as in title.
we put in a different song title in each one of the 6 extras textboxes. Then we query db. If title matches any extra, then we grab the info for that title.

Please read post #5 again (mind that '=' is changed to '.='), i think that is your solution.

Phew! Thanks Marco. I would have never figured out that one. As a rule, when do we put a dot? LOL, looks like I will have to go back to some other scripts I made and start putting dots all over.

= is an assignment, .= is a concatenation
$foo = 'bar';
$foo = 'bar';
results is $foo being 'bar';

$foo = 'bar'
$foo .= 'bar'
results in $foo being 'barbar'

Got it. Thanks. Not bad after 6 hours for just one dot :-)

Hmm ... lol.
SCNR ;)

Examples:

PHP Code:


		
			
$line = '';

foreach (array('line1\n', 'line2\n') AS $text)

{

 $line = $text;

}

$line will now contain

Code:

line2

, since that was the last assignment.

2nd example:

PHP Code:


		
			
$line = '';

foreach (array('line1\n', 'line2\n') AS $text)

{

 $line .= $text;

}

$line will now contain:

Code:

line1

line2

Now that's English! Nothing like the php website where they assumed that you were born a programmer.

Got a tiny problem: Apostrophe

Quote:

WHERE title = 'J'ai besoin de toi'

is giving me an error. How should I handle that?
thanks.

ok, never mind. Instead of a single quote, I put double quotes, escaping them. \"
