Build An Automated PHP Gallery System In Minutes

for making gif thumbnails you need to have gd version which supports gif ... as the code will try to call functions specific to gif ... check your phpinfo() [under gd specifications] it will show you the list of mime types supported by GD installed with your php ...

for this array:

PHP Code:


$photo_types = array( 

'image/pjpeg' => 'jpg', 

'image/jpeg' => 'jpg', 

'image/gif' => 'gif', 

'image/bmp' => 'bmp', 

'image/x-png' => 'png' 

);

you can simply remove the gif listing to disallow any gif uploads ...

PHP Code:


$photo_types = array( 

'image/pjpeg' => 'jpg', 

'image/jpeg' => 'jpg', 

'image/bmp' => 'bmp', 

'image/x-png' => 'png' 

);

Wouldnt this be easier putting the images into the db itself also not just a referance and how would I go about doing this the best way because doing it this way into the file atm is starting to give me the ****s with a coupla updating and syncro issues between different servers that i'm thinking this would be much better of putting the images themselves into the database..

Thoughts on this please....

**mayank** · Sep 15, 2003 09:02

well ofcourse you can do that but i would not advise it ... as mysql space is limited on servers ... so if you are planing to store 100 mb of images in the db, then i am not sure you will find many hosts offering that ...

Is their a better way to name the files then? and on the new server the thumbnail images come up funny colours but the fullsized image is comming up as surposed to any ideas on what is causing this?

**mayank** · Sep 15, 2003 22:20

well the funny colors might be due to GD 1.6.x or lower version which supports only 256 colors ... so when you upload a image it will resize them to a thumbnail using only 256 colors (dithering to the nearest color).

**noddy** · Sep 15, 2003 22:24

will have to check that out but yeah maybe

That happened to me when I first fired up the sample code. I had to mod the code to not do the 1.6 ver. resize but do the 2.0 instead.

how do you mod the code mate to do that?

**noddy** · Sep 19, 2003 21:58

This is my php setting on the server that the site runs on

gd

GD Support enabled GD Version bundled (2.0 compatible) FreeType Support enabled FreeType Linkage with freetype GIF Read Support enabled JPG Support enabled PNG Support enabled WBMP Support enabled

and this is the link to the thumbnails that are comming up strang colors

take a look and give me a guess what it might be caused by

**mayank** · Sep 19, 2003 22:37

which code fragment are you using ... GD 2 or GD 1.x.x ?

But is your code setup to use gd 2.0?

PHP Code:


// Build Thumbnail with GD 2.0



$function_suffix = $gd_function_suffix[$filetype]; 

$function_to_read = 'ImageCreateFrom' . $function_suffix; 

$function_to_write = 'Image' . $function_suffix; 



// Read the source file 

$source_handle = $function_to_read($images_dir . '/' . $filename); 

        

if ($source_handle) { 

// Let's create a blank image for the thumbnail 



$destination_handle = ImageCreateTrueColor ($thumbnail_width, $thumbnail_height);



// Now we resize it 

ImageCopyResampled($destination_handle, $source_handle, 0, 0, 0, 0, $thumbnail_width, $thumbnail_height, $size[0], $size[1]); 

}     



// Let's save the thumbnail 

$function_to_write($destination_handle, $images_dir . '/tb_' . $filename);

its got gd on the server

**Tryst** · Sep 23, 2003 07:39

Hi all,

i've just started this article, and am a bit confused with the code within perupload.php.

PHP Code:


Select Category 

     <select name="category"> 

     $photo_category_list 

     </select> 

   </td></tr> 

   <!—Insert the image fields here --> 

   $photo_upload_fields 

   <tr><td>

Why have U used PHP code within HTML without braking out of the PHP tags. Wont this cause errors??

Tryts

**noddy** · Sep 23, 2003 16:48

that code should have echo <<<__HTML_END
<select name="category">
$photo_category_list
</select>
</td></tr>
<!—Insert the image fields here -->
$photo_upload_fields
<tr><td>
__HTML_END;

around it

Though I think they're waiting on something or other before they release the GIF support in the current GD releases... ?

Its because thats when the patent expires in the EU, if I remember correctly.

You guys have some knowledge abaut this stuff, I am almost ashamed to ask some early beginner questions.
please take a look at this Screenshot and tell me if this is correct so far.

http://www.quickflicks.0catch.com/Fi...togallery.html

Not able to follow the tutorial.

Before we can upload the images, we require a directory in which to store them. Therefore, let’s make a new directory, and name it “photos” (for *nix servers, set write permissions for this directory using chmod, e.g. 777

How do I build a directory in which to store them? Totally lost.

**mayank** · Sep 28, 2003 10:27

well you can do that via your FTP program itself ...
else windows server you can make a new directory by executing the following command:

PHP Code:


    md photos

for *nix servers,

PHP Code:


    mkdir photos

Silly question - but I haven't had time to test this out yet. Assuming that I have GIF (read only) support in my GD library. Shouldn't it be possible for me to create a thumbnail from a gif upload in PNG or JPG format. Or even convert both the full size image and the thumbnail to a supported write format?

And is there going to be a difference with using BMP in the code above, if my GD library lists WBMP Support and nothing that looks like plain vanilla BMP?

thanks

**mayank** · Sep 29, 2003 09:34

well as you just have read-only access ... the only thing you can do is convert it online to a known format as you suggested ...

i have the code working on my home pc. i have uploaded to my webspace and am getting an error message:

Warning: open_basedir restriction in effect.

is this something to do with the code, or is it my hosting company?

i used your code as it and it works well. BUT only 6 from 9 files i tried to upload has been uploaded an resized. The rest is somewhere in nirvana...

9 files together there is only 900KB...

and here is the setting of the php.ini file:

post_max_size = 8M
upload_max_filesize = 8M

timeout was set in php code to: set_time_limit(0)

any idea ???

On the last page of this, you seem o have two functions for deleting photos - both very similar. Which one works? One is mis-labeled 'edit category details'.

**mayank** · Oct 5, 2003 11:03

looks like this code has been added by mistake ... it wasn't in the original draft ... maybe a typo error ...

PHP Code:


Editing Category Details



function delete_photo( $photo_id ) 

{ 

 global $images_dir; 

 $result = mysql_query( "SELECT photo_filename FROM gallery_photo WHERE photo_id='".addslashes( $photo_id )."'" );   

 list($filename) = mysql_fetch_array( $result ); 

 mysql_free_result( $result ); 



 unlink($images_dir."/".$filename); 

 mysql_query( "DELETE FROM gallery_photo WHERE photo_id='".addslashes( $photo_id )."'" ); 

}/

don't use this one ... use the other one ...

**darker** · Oct 7, 2003 15:37

This is just what've been looking for, or.. at least parts of it

Thing is, i'm trying to get this to work pr. user, more or less like this:
http://www.selectdevelopment.com/aut...at.php?v_cat=6

What I mean is that when the user log in, he will be able to create an ad, and uploading 5 pictures trough this gallery.

Anyone have any ideas?
