random thumbs...?

[-okapi-]

just a request...

would it be a hard thing to write an addon for displaying one or more clickable random thumbnails? i think, for a photoblog, especially when it has become bigger, this is a very nice feature, because it invites visitors also to take a look at older images...

what i really love about pixelpost is it's modular structure. that makes me think (sorry, i'm a php layman) that this could maybe be done as an addon...

what is your opinion about that?

[Connie]

I don't think it would be too hard, but I don't know who has the time to do this :oops:

well, as the number of thumbnails is known from the database, it would be not too difficult

- to get this value from the database
- to find a random value between 1 and this value
- to create a link to the thumbnail with this random value

it's just a question of time and testing..

[-okapi-]

thank's for your answer, connie,
yes, i know, it takes time and effort to develop such goodies...

hmm...
all i can do now
is hope,
that somebody,
who has the skills to do it
agrees with me,
that this would be a very nice feature
and
has some time left to...

;)

[raminia]

It is done!
I uploaded it on the addon section.

Random Thumbs (random_thumb.php - version 0.1)
This addon will enables the tag <IMAGE_THUMBNAIL_RANDOM_ROW> which shows random thumbnails from the database. This tag could be used similar to the original date-oriented thumbnail tag <IMAGE_THUMBNAIL_ROW>

Usage:
Place <IMAGE_THUMBNAIL_RANDOM_ROW> in your image_template.html where you want the random thumbnails to appear.

I've done it this way
$thumbs_ahead = mysql_query("select DISTINCT id,headline,image from ".$pixelpost_db_prefix."pixelpost where id!=".$image_id." order by rand() asc limit 0,$thmb_numb");
:D

[-okapi-]

thank you so much, raminia!

perfectly done, and that was really lightning fast...!
amazing work!
i really love this feature.

by the way, i'm wondering what makes a call to a function (hopefully i'm right, maybe i should just say "tags") like <IMAGE_THUMBNAIL_RANDOM_ROW> work only with image_template.html but not with about_template.html for example, while others, like <SITE_RSS_LINK> or <SITE_CALENDAR> work with any page...

again, thanks a lot!

[Connie]

@Ramina,

you are so fast! I just made a similar addon, to train my understanding of php....

but your's is there and that is ok!

@okapi,

this phenomen is becaused some of these tags are generated by the script later than the part for the special template , the script actually does not generate all tags first and then handles the different requests...
:roll:

[-okapi-]

i see...!
as far as i can see, at least ;)

thanks connie!

i wish i had the time to learn more about php, but then, i think, i wouldn't see no daylight any more... ;)

[greentraveler]

I've been wondering if there's a way to display a random fullsize photo for a while but never threw the request out.

But now it looks like it might be possible...is there a way to alter this code to make this possible?

Thanks in advance! :)

[raminia]

Thanks okapi! Thanks Connie!
as okapi asked I've changed it right away to show 5 new thumbnails withought the displayed image as a thumb.

I put the old code here for every one who might be interested in the first version

random image is so easy! It is done! I'll post it in minutes

[greentraveler]

WOW...thank you very much!

[-okapi-]

exciting things are happening here!

[raminia]

welcome;)

I post it in the addon section. Also I opened a new thread with "Random Image Link" in the title for who search for that specific feature.

[raminia]

: ))
reading my writings in the description and these threads make me laugh ... I made many grammatical mistakes. That's because I'm lacking sleep and people make many mistakes in their symbolic level of concious when they are sleepy! oh that's a fact and I'm expericing it. It's about 2 am here...

[raminia]

... I've changed it right away to show 5 new thumbnails
Oh I've reported it wrongly. It's not just fixed 5... it's as much as you mention in your amdin/option tab and mine is 5.

[-okapi-]

you definitely need some sleep ;)

(edited: sorry, this was a crossposting, i meant it as a joke, not referring to your above post!)

so please ignore the following ;)
i have tried the random image link on my local server environment: but it only seems to work with a root install of pixelpost. the script seems to ignore the folder where pixelpost is installed in. so the output link doesn't work...

[raminia]

oh yes!!
the addon is ok. the usage is not.
use this new one and it should be ok.
&lt;a href='$PHP_SELF?showimage=&lt;IMAGE_RANDOM>' > Random photo </a>

...I'll go to seeeelp!

[-okapi-]

i apologize!
the first one works nicely, but only with image_template.html. i had tried it with other template files.

good night and thanks a lot!

[usafdcc]

Is there a way to post this on another page like an about page, links page and not just the image_template page

[raminia]

humm... There is some way. I'll try them.

[-okapi-]

good morning, raminia!

:)

for me this is a basic question...
connie has tried to explain it to me, but -
testing php galleries i have always asked myself why code couldn't be written in way to get elements (calls of functions, tags...) that can be used with every template page. then, we would be free to build the site entirely individually, like with building blocks. we could have thumbnails, images, everything, on every page we want...

maybe this is a silly question...
but i'm curious.

[raminia]

I've made changes to the addon and its now on version 0.3 !
Update: this tag is now availabe on all page of pixelpost photoblog.

[raminia]

That's not silly question but what are you suggesting is a scripting language for photoblog! There is some sort of thing but limited on localservers. If you are familiar with Blogger.com you could see it behave in a similar manner. It has certain tags available for all tasks that a blogger needs and in the publishing section replaces all these tags with corresponding content in a static HTML code.

you can do such thing in your website but u need to connect to database and grab the tags. If you see my addon for displaying thumbnail on other pages of the website you could see a primary attempt to do it there. The exception is I did not make special tags (e.g. &lt;latest_thumb> ).

[raminia]

that's the addon I mentioned in the last reply for "Latest Thumbnail in other pages of the website "

thank you very much for your work, raminia!

i'm looking forward to see the updated code in action in the evening...

have a nice day!

sorry, i haven't been logged in!

[raminia]

welcome.;)
to see it in action see my about page. I made it today al last!

[raminia]

UPDATE: version 0.3.1 bug killed!
- The problem of not mentioning the width an height of the thumb in the image tag is solved. Tested and OK on Firefox and IE6.

This bug was the reason of not showing thumbs in IE6 on pager except the main page.

I'm done here!

[BandonRandon]

How would i make this display only 1 image? Thanks

[BandonRandon]

well i got it to work, as i am new to pixle post i didn't see the number of thumb rows in the admin page so i did it the hard way and modified the limit of the database to "1" but i acually ended up just copying random_thumb and renaming it to create a file that will in the php let you set the number and changed the tag from <THUMB_IMAGE_RANDOM_ROW> to THUMB_IMAGE_RANDOM> I figured this will allow me to have the flexibilty to see how many to display in the future.
