Simple Plug-in not Working.

This is a continuation from another thread, but the content has already changed sig. from the original thread.

Trying to get the latest 6 thumbails to display under the navbar. "highlightthread" is indeed the name of the table as I forgot to add the prefix.

Here is the plugin:

PHP Code:


		
			
$highlightthreads = $db->query_read("SELECT * FROM highlightthread ORDER BY reference DESC LIMIT 0, 6); 



while ($row = mysql_fetch_array($highlightthreads)) {

echo "<img src=".$row["imageurl"]." />";

    }

Screenie: http://img80.imageshack.us/img80/1023/problemlf3.jpg

Last line on the navbar, I just plucked in $highlightthreads , but to no avail. Nothing is showing up in the source either when I load forumhome so I'm sure I've gone wrong somewhere.

Any ideas? Many thanks :)

Instead of echoing the image tags, save them into a variable, and that's the variable you need to put in a template.

PHP Code:


		
			
$highlightthreads = $db->query_read("SELECT * FROM highlightthread ORDER BY reference DESC LIMIT 0, 6"); 

while ($row = $db->fetch_array($highlightthreads)) 
{
    $image .= '<img src='.$row['imageurl'] .' />';
}

Try that, then use $image in your template to show the images.

It's a good habit to initialize your variables $image = ''; before you start concatenating information onto it.

Analogpoint & Opserty,

Thank you very much for your help. I've edited the code to show this now:

edited, see below:

--------------- Added [DATE]1192514327[/DATE] at [TIME]1192514327[/TIME] ---------------

Interesting, when I load the PHP through logicians template it displays the last 6 as the code states. However when I run it through the plugin I only get the last value (i.e. the 6th). Any thoughts on what may be causing this? Note: $highlightimage is situated at the bottom of the navbar.

New code:

PHP Code:


		
			
$result = @mysql_query('SELECT reference, imageurl, threadurl FROM highlightthread ORDER BY reference DESC LIMIT 0, 6');
if (!$result) {
exit('<p>Error performing query: ' . mysql_error() . '</p>');
}

while ($row = mysql_fetch_array($result)) {
$highlightimage = $row['reference'];
}

Thank you :)

Change:

PHP Code:


		
			
$highlightimage = $row['reference'];

To:

PHP Code:


		
			
$highlightimage .= $row['reference'];

Thank you Marco, still a lot to learn :)

Think the only issue I really have left is now "how do I seperate the data?". Currently, it's outputting <a href="url1url2url3url4url5url6"> when I'd like it to create the link for each of the url's. Code now is as follows:

PHP Code:


		
			
$result = @mysql_query('SELECT reference, imageurl, threadurl FROM highlightthread ORDER BY reference DESC LIMIT 0, 6');

if (!$result) {

exit('<p>Error performing query: ' . mysql_error() . '</p>');

}



while ($row = mysql_fetch_array($result)) {

$threadurl .= $row['threadurl'];

$imageurl .= $row['imageurl'];

eval('$highlights = "' . fetch_template('highlights') . '";');

}

Code in template $highlights, pretty straightforward..

PHP Code:


		
			
<a href="$threadurl"><img src="$imageurl"></a>

Thank you again for all the support, learning a lot by all means.

Change:

PHP Code:


		
			
while ($row = mysql_fetch_array($result)) { 
$threadurl .= $row['threadurl']; 
$imageurl .= $row['imageurl']; 
eval('$highlights = "' . fetch_template('highlights') . '";'); 
}

To:

PHP Code:


		
			
while ($row = mysql_fetch_array($result)) 
{ 
 $threadurl = $row['threadurl']; 
 $imageurl = $row['imageurl']; 
 eval('$highlights .= "' . fetch_template('highlights') . '";'); 
}

Thank you Marco, that did the trick. I have been trying to figure out how to populate the thumbnails in 3 rows, 2 per row (total 6), i.e.:

thumb1 thumb2
thumb3 thumb4
thumb5 thumb6

Now obviously I could probably use 3 queries, but I'm thinking this is probably inefficient and there is a better solution. What function or code would I need to insert to make such possible?

Many thanks :)
