Using Combined Template Conditionals

[Jay Lee]

I'm trying to understand how to use conditionals in templates, using the following thread as an initial guide:

https://vborg.vbsupport.ru/showthread.php?t=217570

So basically what I'm trying to do is to show a track listing. Let's say the following is what's in the database:

Field "trackartist": Artist 1, Artist 2, Artist 3
Field "tracktitle": Title 1, Title 2, Title 3

So I need to figure out how to convert the following php code so that it's compatible with vBulletin:

$doquery = mysql_query("SELECT trackartist, tracktitle FROM `tracklisting`");
$numberoftracks = mysql_num_rows($doquery);
$count = 0;

for ($i = 0; $i < $numberoftracks; $i++)
{
$trackartist[$i] = mysql_result($doquery, $count, "trackartist");
$tracktitle[$i] = mysql_result($doquery, $count, "tracktitle");
echo $trackartist . " - " . $tracktitle . "<br>";
}

The output should be simple:

Artist 1 - Title 1
Artist 2 - Title 2
Artist 3 - Title 3

The problem is, I don't know how to combine template conditionals, meaning I was only able to show each variable separately:

<vb:each from="trackartist" key="character1" value="trackartist">
<li> {vb:var trackartist} </li>
</vb:each>

Output:

Artist 1
Artist 2
Artist 3

<vb:each from="tracktitle" key="character2" value="tracktitle">
<li> {vb:var tracktitle} </li>
</vb:each>

Output:

Title 1
Title 2
Title 3

The closest I was able to get to the correct result was the following:

<vb:each from="trackartist" key="character1" value="trackartist">
<vb:each from="tracktitle" key="character2" value="tracktitle">
<li> {vb:var trackartist} - {vb:var tracktitle} </li>
</vb:each>
</vb:each>

Output:

Artist 1 - Title 1
Artist 1 - Title 2
Artist 1 - Title 3

So how do I get the correct result? Any help would be greatly appreciated!

Just concat the HTML output in the loop.

PHP Code:


$tracks = mysql_query("SELECT trackartist, tracktitle FROM tracklisting");

$tracks_bit = '';
while($track = mysql_fetch_array($tracks, MYSQL_ASSOC)
{
    $tracks_bit .= '<p>' . $track['trackartist'] . ' -  ' . $track['tracktitle'];
} 


Then register the variable, and you should have the correct output.

I knew I was missing something simple! Your code works! Thank you so much!

It would be even better if you didn't use HTML in the code.
Instead of

PHP Code:

while($track = mysql_fetch_array($tracks, MYSQL_ASSOC) 
{ 
    $tracks_bit .= '<p>' . $track['trackartist'] . ' -  ' . $track['tracktitle']; 
} 


create a template for each bit and do something like

PHP Code:

while($track = mysql_fetch_array($tracks, MYSQL_ASSOC) 
{ 
$templater = vB_Template::create('tracks_bit');
    $templater->register('track', $track);
$tracks_bit .= $templater->render(); 
}

Thanks for the additional tip Retal. I'll use your code and if I encounter any problems I'll post questions.
