Recordset Help For Random Image From Galleries

Hi, can someone help with the sql for selecting a random image from the pg1_gallery_images table. Here is what I have so far but when I check the image properties in the browser I am missing some stuff. I just want to show a random image without the gallery itself. I can show the image I just need to get the correct path.

SELECT CONCAT(file_prefix,'.', file_ext)
FROM pg1_gallery_images
ORDER BY Rand() LIMIT 1



Thanks Chris

your query will need to return the galley id and image size as well:

SELECT CONCAT(gallery_id,'/',file_prefix,'_782p.', file_ext) as fileName
FROM pg1_gallery_images
ORDER BY Rand() LIMIT 1


then in the image tag, add the relative path to the images folder:

<img src="images/<?php echo $row_RecordsetName['fileName']; ?>" />

Thanks Jason, I think I'm almost there. My problem now is the query returns the gallery folder number not the name so I think I need a join on the other table & I think the title in that table is the folder name, is this correct to get the right path? Below is the query output & the number 6 should be the folder (I presume).

6/nina_782p.jpg



Can you help me a bit more to complete the join or syntax of the query?

Thanks Chris

you dont need a join, the gallery images are stored in a folder that is named with a number.

look in the files system on your server, you will see in the images folder for the gallery, a folder named 6, with the gallery images inside it.

Thanks Jason. All working fine now. I just had to change

<img src="images/<?php echo $row_RecordsetName['fileName']; ?>" />

to this

<img src="../Powergallery/images/<?php echo $row_rsRandomImage['fileName']; ?>" />



as my images folder is in a folder called "Powergallery" & obviously my recordset is called "rsRandomImage"


I appreciate your help.

Yes, you do need to make those changes to fit your environment, glad to hear it is working.

A bit more advanced image linking

Hi Jason, everything is working but I have had some people asking to get to the actual image in the power gallery from the random ones they clicked on in another page, at the moment I am just sending them to the gallery & then they find the image themselves.

I thought I could pass a url parameter but noticed that it doesn't have one, when viewing images in PG.

I have made another table that has the page URLs (pg1_galleryurl_grl) so I can get to the gallery, but how do I show the actual image they clicked on.

Below is the sql I am now using, as I said it all works fine I just need to get to the actual image

SELECT CONCAT(gallery_id,'/',file_prefix,'_782p.', file_ext) as fileName,pg1_gallery_images.description,pg1_gallery.title,description, pg1_gallery_images.file_ext, pg1_gallery_images.gallery_id, pg1_gallery.id, pg1_gallery.title, pg1_galleryurl_grl.galleryurl_grl
FROM ((pg1_gallery_images LEFT JOIN pg1_gallery ON pg1_gallery.id=pg1_gallery_images.gallery_id) LEFT JOIN pg1_galleryurl_grl ON pg1_galleryurl_grl.idgallery_grl=pg1_gallery.id)
WHERE gallery_id != '3'
ORDER BY Rand() LIMIT 2



Regards Chris :)

Yeah, that's not going to be supported in power gallery, it would take a lot of custom coding to accomplish.
