An image for each contributor

Is it possible to associate an image (ie, a pic of the contributor) to each contributor?
Cheers,
Davide

This can be easily done with a plugin.

I just created one and added it to the additional_plugins CVS module of serendipity. Here's the code of it, just save it as "serendipity_event_authorpic.php" inside a new folder "plugins/serendipity_event_authorpic" - then you can activate it in your plugin configuration.

The plugin looks for images called just like the authorname in the img subfolder of your template directory; so if the authorname is "garvin hicking", it will fetch a file from "templates/default/img/garvin_hicking.jpg".

Have fun with it!

Code: Select all

Thanks Gravin, a BTO plugin iss more than I expected.
I am really sorry to report that there probably is a bug:
That's what I find in the plugin panel, in the Event plugin section:

Parse error: parse error, unexpected T_STRING, expecting T_CASE or T_DEFAULT or '}' in /web/htdocs/www.cnomania.it/home/serendipity/plugin ... horpic.php on line 4

I'd like to fix this bug myself, but I have no knowledge of php.
Thanks a million anyway,
Davide

I suppose you made a mistake by copy/pasting the script from here? What is line 4 of your file? I can mail you the right file, if you supply me with your mail adress :-)

Regards,
Garvin.

Well, thanks again!
If all pricey application were supported as this free one... :-)
Maybe something went wrong in the copy/paste process...
You can mail the file at

Cheers again,

Hi Garvin, and hello to all the folks in the forum.
I have been experimenting with your "BTO" :-) Picture-of-the author plugin. I have put it in the correct directory, and I can see it in the administration panel; the plugin seems to be working. Yet no picture appears... I have inserted a picture for my user, Nutsmuggler, in the Idea template directory (Idea is indeed the template I am using); I have kept the capital N, since Unix is case sensitive, right? No image...
Can you suggest me what the problem might be?
Cheers,
Davide

Posted: Fri Dec 03, 2004 10:49 am

nutsmuggler,

you are right with the capitals; but you need to put the image in templates/idea/img/Nutsmuggler.jpg (or .gif or whatever extension you configurued)...

Regards,
Garvin

Posted: Fri Dec 03, 2004 11:15 am
by nutsmuggler
The image is exactly in the templates/idea/img/ directory, but there is no trace of the picture in the weblog entries...
Just a question: is this plugin applying to ALL the ntries or just to the new ones?
What do you think is the problem?

Thanks again,
Davide

Are you using version 0.8 of serendipity? If so, the caching plugin may interfer; can click on 'rebuild cached entries' in that case?

If you're using 0.7 we would have to add a little debugging. Have you looked at the HTML source and see there if there's any image HTML printed?

Regards,
Garvin.

I'm using version 0.7.
I've looked at the page HTML source; I don't think there is any image in the source. Here's the extract of a news entry:

Thanks for letting me know.

Now, please edit your plugin file and alter this piece:

Code: Select all

if (isset($this->found_images[$eventData['username']])) {
    // Author image was already found previously. Display it.
    $eventData['body'] = $this->found_images[$eventData['username']] . $eventData['body'];
} elseif ($img = serendipity_getTemplateFile('img/' . preg_replace('@[^a-z0-9]@i', '_', $eventData['username']) . '.' . $this->get_config('extension'))) {
    // Author image exists, save it in cache and display it.
    $this->found_images[$eventData['username']] = '<img class="serendipity_authorpic" src="' . $img . '" alt="' . AUTHOR . '" title="' . htmlspecialchars($eventData['username']) . '" />';
    $eventData['body'] = $this->found_images[$eventData['username']] . $eventData['body'];
} else {
     // No image found, do not try again in next article.
    $this->found_images[$eventData['username']] = '';
}
to this:

Code: Select all

if (isset($this->found_images[$eventData['username']])) {
    // Author image was already found previously. Display it.
    $eventData['body'] = '<!-- reusing -->' . $this->found_images[$eventData['username']] . $eventData['body'];
} elseif ($img = serendipity_getTemplateFile('img/' . preg_replace('@[^a-z0-9]@i', '_', $eventData['username']) . '.' . $this->get_config('extension'))) {
    // Author image exists, save it in cache and display it.
    $this->found_images[$eventData['username']] = '<img class="serendipity_authorpic" src="' . $img . '" alt="' . AUTHOR . '" title="' . htmlspecialchars($eventData['username']) . '" />';
    $eventData['body'] = '<!-- img found -->' . $this->found_images[$eventData['username']] . $eventData['body'];
} else {
     // No image found, do not try again in next article.
    $this->found_images[$eventData['username']] = '<!-- no image img/' . preg_replace('@[^a-z0-9]@i', '_', $eventData['username']) . '.' . $this->get_config('extension') . ' was found (' . $img . ') -->';
}
I added some more verbose HTML-comment output which should in any case be added to your blog.

I am online in #s9y.org on freenode if you want some "realtime" help with this :-)

Regards,
Garvin.

I've modified the file; still I can see no changes in the page layout.
Here's the HTML code:

Code: Select all

 <div class="serendipity_Entry_Date">
        <h3 class="serendipity_date">Domenica, novembre 28. 2004</h3>

        <h4 class="serendipity_title"><a href="/serendipity/index.php?/archives/7-Cinque-cereali,-il-film.html">Cinque cereali, il film?</a></h4>

        <div class="serendipity_entry">
            <div class="serendipity_entry_body_folded">La notte porta consiglio, recita l'adagio popolare.<br />
E la notte scorsa di certo ha portato consiglio agli Accademici, o meglio, alla piccola delegazione riunita per il drink della buonanotte al Leon d'Oro.<br />
I cattedratici, meditando fra un bicchiere di birra e una tazza di latte, hanno deliberato la necessità di riprendere in mano un progetto di vecchia data, rimasto, ahinoi, sempre sulla carta. <br />
Il tempo è giunto, si sono detti, di mettere mano alla macchina da presa, e far vedere all'orbe terraqueo chi siamo.<br />
Eh sì, avete capito bene, se la fortuna ci sarà propizia avremo per le mani una produzione cinematografica firmata "Cinque Cereali".<br />
Le maggiori difficoltà sono sul versante del finanziamento, anche se pare che una nota ditta di grappe di Vigolovattaro sia interessata alla produzione.<br />

This definitely seems like you haven't installed the plugin.

You need to go to "Plugins" and then choose the plugin to insert from the dropdown list of the lower part of the screen ("Event plugins") and click on 'insert plugin'...can you make a screenshot of how your list of installed event plugins looks like? The plugins isn't executed at all, because then the HTML comments would be seen...

Regards,
Garvin
