Hi Guys,

 

I have been working on a photo gallery lately...  done a couple of tutorials to help me understand how to upload, and resize thumbnails upon uploading...  some of the stuff is pretty complicated but I am getting there in terms of my understanding.

 

What I am trying to create is a back-end application whereby a person can go into their password protected area, click on the link 'Create a photo gallery' and then start uploading pics.  But the thing is, all of the 'image gallery' tutorials I have looked at create one basic photo gallery with all of the photos contained within.  I am designing a website for a mate who is travelling.  I want him to be able to create a photo gallery for each new place that he visits.  Therefore in his main photo page he will have different links to display different galleries of the places he has been to, which friends and family can select.

 

I suspect that I need to do this using mysql.  I have been using facebook a lot lately, and would like to create a similar style photo gallery.  The user clicks on the 'create a gallery' link and then they are taken through to a page where they input the name of the Gallery and a brief description.  Once they have clicked OK button then they are taken to a page where they can upload and add comments for each photo.  Then once this has been done each different gallery is displayed on the website.  This is what I am unclear about...  how to do this.  Would I need to create a few tables in MySQL, one for the gallery name (unique id, gallery_name, description), then another for the uploaded photo (photo_id, image, comment, gallery_id)?

 

I'd be very grateful if someone could throw any ideas at me as to how I can do this.

 

Many Thanks

 

Stu

I have an image upload script that creates thumbnails and larger images.

 

I can choose which gallery I would like them placed in.  Really all the images are uplaoded to either a thumbnail directory or the large directory but the purpose of using the mysql database is to store the images names and which gallery they belong to.

 

<?php 
$idir = "../images/gallery/full/";   // Path To Images Directory 
$tdir = "../images/gallery/thumbs/";   // Path To Thumbnails Directory 
$twidth = "100";   // Maximum Width For Thumbnail Images 
$theight = "75";   // Maximum Height For Thumbnail Images 
$ldir = "../images/gallery/large/";   // Path To Thumbnails Directory 
$lwidth = "400";   // Maximum Width For Thumbnail Images 
$lheight = "300";   // Maximum Height For Thumbnail Images

$pic=($_FILES['imagefile']['name']);
$gallery = $_POST['gallery'];

if (!isset($_POST['gallery'])) {
?> 
<fieldset>
    <legend><b>Image Gallery Upload</b></legend>
<form enctype="multipart/form-data" action="<? $_SERVER['PHP_SELF']; ?>" method="post">  
    <p style="margin-left:10px;">Gallery to upload to:<br />
    <select name="gallery" size="1">
    	<option value="jack">Jack</option> 
    	<option value="honeylands">Honeylands</option> 
    	<option value="events">Events</option> 
    	<option value="art">Art Auction</option> 
    </select>
    	    <p style="margin-left:10px;">Image to upload:<br />
    	    <input type="file" name="imagefile" style="width:450px" /><br /> 
    	    <P><input type="submit" name="submit" value="Upload Image" class="submit-button" style="margin-left:10px;" /></p>
    	</form>
</fieldset><br /> 
<?}
else {   // Uploading/Resizing Script

    if ($_FILES['imagefile']['type'] == "image/jpg" || $_FILES['imagefile']['type'] == "image/jpeg" || $_FILES['imagefile']['type'] == "image/pjpeg") {

Ah, what a nice surprise...  two replies so quickly.  Thanks guys.

 

I know that I have got to start learning more SQL as I will need to join tables (won't I?) to achieve what I want.  I am pretty much a newbie at PHP, and need to find time to look more into SQL.  But this info you have given me shows I am on the right lines.

 

Am busy now but will post back about this later...  thanks again, I can tell this forum is going to be very valueable to me.

 

Cheers

This is ballpark of what you want for the database I think.

 

user

-----

id

username

password

 

gallery

---------

id

name

description

 

photos

----------

id

gallery_id

thumb

full

 

user_gallery

-----------

user_id

gallery_id

 

Alright dbo,

 

I am a little confused.  Why would I have user_id in the user_gallery.  Wouldn't this table contain gallery_id and (photo)id?

 

Cheers
