How To - Validate Multiple Image Upload

Ok... I have a page where user can insert some informations in a database and also upload related images (without saving to the database).
This is a free site that I'm developing for humanitary proposes, and I do want him to be good. If people responsable for submiting information of an abandonned dog do not upload an associated image, the site will have no sucess. So, its mandatory to upload some images of the dog.
Question: How can we validate the multiple upload image SB to be "required" and IF no image is uploaded then, no Insert transaction will be made?
Thanks

Hi Marcio,

Question: How can we validate the multiple upload image SB to be "required" and IF no image is uploaded then, no Insert transaction will be made?
>>
well, there´s a problem with using the Multiple Image Upload *without* saving image names etc to a table :: the Insert or Update transaction that´s required to use this "multi upload" flavor, will be executed *first* and
(just hope this isn´t plain wrong, but I don´t think so) has no clue of what´s exactly getting triggered afterwards
This is a sort of "master/slave" chain of actions where the "slave"
(the upload process) will just do his work after the "master"
(the Insert transaction) has successfully done something else before -- but not vice versa.
About the validation as such :: ADDT will always let you validate fields, as long they belong to a certain transaction -- but the "without save to database" image upload procedure is not part of the transaction, that´s why it´s not validatable.
I would suggest using the "with save to database" multi-upload flavor instead. This variant will be adding an Insert transaction, and the uploaded file names will be part of this transaction and hence are supposed to be validatable. I hope :-)
Now you might wonder why, because you assumingly don´t need all the file name info that has been stored. That´s right, but if you´d store that stuff in a "dummy" table which has no other purpose than to simply "be there", it might make some sense -- noone will ever force you to query that dummy table, so what ? :-)
That´s actually all just some "food for thought" for you, as I never tried that myself -- but from knowing ADDT´s "logic", I´m somewhat certain it will work out after all.

Multiple Image Uploading Question

Please forgive my ignorance here but I saw the question on multiple image uploading and this is something i have been trying to do for a few days now without any success.
I am using CS3 with ADDT and PHP
I want to allow my users to be able to upload say 5 pictures at a time, each user has multiple photo albums the names of which are stored in mysql table, the image name is stored in a different table with a reference to the album id.
So, I assume that i put an insert record on the page, I followed the usual process used to have a single image upload and thought it would give me or add the extra file field options on the form when telling the multi upload to allow 5 images to be uploaded, not the case. Do i have to create a form on the page first with 5 file fields or am i just missing the plot here.
Sorry if this is just something that seems simple but i just don't seem to be able to get it to work at all. I have no working example to look over and have serach google to see if there are any tutorials for doing this but can't find any at all.
Thank you in advance of any help and guidance given
Regards
Ray

Hi Günter
Thank you for your reply and also for the great tutorial site you run which has helped me quite a lot with several things.
ok, so i am maybe a little confused here, so what is the multiple image uploader for if not for uploading multiple images, and how does it give you the option to select more than one file or is it that you can't use it when inserting the image file into a database?
Please forgive my ignornace again, i can see when i have tried using the multiple image upload thatit puts a text link called upload, what is that for because it doesn't seem to do anything on the page i have tried it on?
Kind Regards
Ray

Can you move a 'Multiple Image Upload' button into the 'Update Form'?

I am able to creat and an Update form and an image upload using the "Update Form Wizard" tool and the "Multiple Image Upload" tool succesfully.
 
 The problem comes when I try to move the "UPLOAD" button inside the Update form. Right now it looks like this:
 http://www.webritesolutions.com/Test/upload/now.JPG
 
 This is how I would like it to show:
 http://www.webritesolutions.com/Test/upload/tryingto.JPG
 
 I want to "Upload" button to go next to the "Update record" button. When I do this I get a javascript error and the "Update record" button is disabled.
 Here is the code of what I tried to do:
 
 
 
 
 
<table>
<tr class="KT_buttons">
<td>
<?php // Multiple Upload Helper echo $muploadHelper->Execute(); ?>
</td>
<td colspan="1">
<input type="submit" name="KT_Update1" id="KT_Update1" value="Update record" />
 </td>
</tr>
</table>
 
 Here is the Javascript error:
 http://www.webritesolutions.com/Test/upload/error.JPG
 
 thanks for your help.

A control can only appear once in the visual tree. So you have to remove it from the Grid before you can add it to the DockPanel.
This code will move the Border element from the Grid to the DockPanel when you click the button:
Private Sub Button_Click(sender As Object, e As RoutedEventArgs)
Dim border = CType(LayoutRoot.FindName("myborder"), Border)
LayoutRoot.Children.Remove(border)
contain.Children.Add(border)
End Sub
<StackPanel>
<Grid x:Name="LayoutRoot">
<Border x:Name="myborder" BorderBrush="Black" BorderThickness="2">
<TextBlock>...</TextBlock>
</Border>
</Grid>
<DockPanel x:Name="contain" Background="Yellow">
<TextBlock>2</TextBlock>
</DockPanel>
<Button Click="Button_Click" Content="Move"/>
</StackPanel>
You can try it for yourself. But please post your code as formatted text and not as embedded images if you want anyone to be able to reproduce your issue and help you in the future.

Multiple Image Upload with Save to DB - any help would be appreciated

Hi - I'm running into the following issue when using the Multiple Image Upload with Save to DB behaviour.
When I click the link to upload multiple files, I am given the list of local files to choose to upload. No problem here - I can select multiple files.
When i select choose, the uploader shows the progress but hangs at 0%
However (if I cancel the uploads), the first image of the group is uploaded and it's corresponding database entry is entered correctly.
Anyone else have this hangup? If so how did you get around it?
Thanks!
Dan

Just thought I would update.
The problem seems to be related to redirecting.
I had specified a redirect page, which of course stops the flash file from continuing to upload images after the first one.
Anyone know how to change this so when the flash uploader finished it goes back to a list page?
Thanks again.

Multiple image upload with save to database wizard problem

hi,
i need to upload multiple images (6) in a table called pictures. i will need the names stored in the database and the files uploaded on the server. since i am new to dreamweaver i can not figure out on how to make this work.
the multiple image upload wizard uploads the images fine and creates a subfolder with the right id but i have no file names in the database at this point. i tried the multiple image upload with save to database wizard but i only get one upload button. it worked fine with one image but i need 6 pics uploaded. the i tried to first upload the pictures with the multiple image upload wizard and use the update wizard to add the names afterwards but that did not work either. hmm. would be great if someone could help me out.
thanks, jan

Thank you for the responses. I have already updated awhile ago, so I am wondering what happened. Not sure if during the server update, some files were replaced (unless I totally forgot to update to 1.0.1 on this site). So I reinstalled 1.0.1, deleted the includes folder from the server and uploaded my includes folder and it now works again.
Again, thanks for the help.

Multiple Image upload with save to database

Hi everyone,
I wonder whether anyone can help me, I have been trying to use the multiple image upload with save to database wizard. When I create the page and upload it and then view it in Safari the only thing that is on the page is an upload button. When I press the upload button I am able to browse my files and select them. When this window closes a flash loading value is shown but no images have been uploaded.
Am I missing anything? I have had no problems uploading single files and creating albums. I want to create an online gallery so that I can do a multiple upload to a specific album if this is possible.
Cheers
Sarah

Hi Sarah,
>>
but only the filename appeared in the database and no other information was stored.
>>
that´s how it´s been designed also in the "single upload" -- the path_to_the_folder where the files sit in have to be determined elsewhere
>>
{wedimg_idalb}
>>
I don´t see any reference to this "dynamic data" placeholder in any of your table columns you posted -- where does this one come from ?
>>
1. I have multiple clients and each client has their own set of images.
2. Each set of client images must be linked to an album via the album ID
>>
do you have any "foreign key" which is related to the user_table´s ID in order to make user ID 2 upload his images in album ID 2 ? How will the upload page "know" where the images are going to be uploaded to ?
>>
and the album page, wedding_alb
>>
to my mind *this* table would itself need a foreign key to the user_table in order to "map" record 2 to user ID 2 -- or do I miss something ?

Multiple Image Upload and watermarking

Hi,
I am using a gallery script which takes main images from a dynamic folder and creates thumbnails on the fly.
It gets the main images dynamically from
$config['fulls'] = $_GET['imgfolder_id'];
Then GD is applied to create thumbnails on the fly. There is no GD role for the main images. I use lightbox to show pop-up image. And the images are uploaded to a dynamic folder using ADDT multiple image upload server behavior.
My requirement: want to apply water mark on the large (pop-up) image. Not on the thumbnail.
Is it possible to have the water mark applied at the time of Multiple Image Upload?
Thanks for any help
Jay

Hi Jay,
if it were a single image upload, I would have suggested to apply a PHP watermark script to the uploaded image by embedding that code in a Custom Trigger, type AFTER -- but as the multiple upload gets proceeded by a flash file, I have no clue how to do that.

Multiple Image Uploader renaming thumbnails

I am having a blast with the ADDT! For a php noob such as myself this stuff is great, just what I have been looking for.
If only I knew how to stop ADDT's multiple image uploader FROM RENAMING THE UPLOADED THUMBNAILS.
Like this: myImage.jpg is renamed to myImage_135x150.jpg
I can deal with it stashing the thumbnail in a separate folder, but the name of the uploaded image and the thumbnail must remain the same!
I did manage to figure out where to change the thumbnails dimensions, but not the name itself...
Thanks for such a great tool,
Jason

Hi Jason,
ADDT´s default thumbnail renaming rule is defined in the file "includes/tng/triggers/tNG_DynamicThumbnail.class.php" -- at the end there´s a function named "Execute", and in here you´ll find the following:
a) $thumbnailName = path_info['filename'].'_'.$width.'x'.$height.'_w_'.$hash.(isset($path_info['extension'])? '.'.$path_info['extension']:'');
this needs to be changed to:
$thumbnailName = path_info['filename'].$hash.(isset($path_info['extension'])?'.'.$path_info['extension']:' ');
b) tNG_deleteThumbnails($thumbnailFolder, $path_info['filename'].'_'.$width.'x'.$height, $hash);
this need to be changed to:
tNG_deleteThumbnails($thumbnailFolder, $path_info['filename'], $hash);
As always, please backup the original file before making such changes ;-)
Cheers,

How do I add image upload to web app edit template?

How do I add image upload to web app edit template. When creating fields I am selecting image from the field type. But the only way to upload and image is when I create the web app item within the admin. The option to upload an image is not available when the user submit web form opens.
Wont send any of these questions through this email anymore but really needed assistance.
Thanks,
Gordon

On the Details tab of the Web App setup, under Web App Item Options; have you ticked "Allow File Upload" and specified a Default Upload Folder?

how to have multiple images on the same screen? like in the movies where you see several actions at the same time ....
i don't find a tutorial in adobe tv....
thanks !!

The short answer is that you'll put the source clip(s) for each inset on a different video track, all stacked up. Then use the Scale and Position effects (under "Motion" on the Effect Controls panel) to reduce their size and place them where you want.
If the content of an inset will involve edited content (where you're cutting among various clips or just trimming out unwanted content from a single clip), then you'll probably find it easier to do all those edits in one sequence, then nest that sequence in the master sequence, where you apply the Scale and Positioning effects. That will save the step of applying the scale and position effects to each edited track item.

ADDT multiple image upload: "error 500"

Right now, I have managed to get the update record form wizard working, the right input ends up in the correct fields in the database.
So I'm left fighting with the "multiple image upload", which gives me an "error 500" message (error connecting to server)
The window does show me the correct files in the correct folder, but when I try and upload an image I always get the error 500 message.
I have read that the "multiple file upload" uses a temporary folder, and Im assuming that the "multiple image upload" does the same, and I suppose that I should CHMOD that folder to 777.
Do you know where I can find that folder?
Can anyone help me with that error?
Please?
Sorry about my name, I tried a lot of other names, and all were taken, but this random name went just fine

I thought it did - When I used the upload and save to database it saved the original images in a folder and created a sub folder called "thumbnails" and saved the thumbnails - origianl filesname just with width and height appended at the end.
I checked my server files and their definately created.
I browsed the java script and the help files which mentions it does this but I would like to be able to change the naming format of the thumbanils if possible

Multiple image upload CRASH!!! but works with simple image upload

I'm getting MAD.
I'm using php and GD
While the simple image and re size works like a charm, the multiple image upload or the multiple file upload have a strange behavior.
It opens the pop-up with flash, then eventually shows me files or thumbnails but when I try to up load I just wait and get the typical "system becoming unstable" flash error.
As I can see the directory is always generated (I've tried also to put a static directory) but after stargin the upload the flash uploader just crashes and no result.
Any help would be really appreciated

Hi Fonzie,
as the folder is getting created, the issue you´re having is not related to wrong folder permission - it´s something else...
As I wrote before, che common upload and resize function works perfectly
this one works perfectly, because it´s just one file to upload and to process, wheras doing that with multiple files might collide with some settings on your server
So for sure it's not a simple issue as the max filesize
Are you sure ? Did you check the current "max_upload_filesize" setting ? As long you don´t check it, you can´t know :-)
As a general rule of thumb, it´s important to be aware of the fact that uploading & resizing images on the server might collide with several PHP settings -- and the more images you upload and resize in one swoop, the closer you´re getting to these limits respectively might even be exceeding them. The following "directives" are those which have an effect on whether your image/file upload & processing will work or not:
- "max_upload_filesize" :: is sometimes set to just 8 MB on a shared hosting, sometimes 16 MB, sometimes more. This setting will affect the file upload procedure only
- "set_time_limit" (e.g. 30 seconds) :: if the execution time of a script exceeds this limit for whatever reason, the server simply shuts it down without letting you (respectively the flash uploader) know it´s been shut down. This *might* be the reason why ADDT´s flash uploader hangs respectively returns that error message after some time, because it´s waiting for some response from the server which never comes.
- "memory_limit" (e.g. 8 MB) :: this directive is a sort of "allocated server RAM" for your account, and it´s in particular the image resizing process which will grab more or less memory resources -- the higher the the resizing factor is, the more RAM is spent, and the more images are getting resized in one swoop, the worser it gets.
However, all these PHP directives can be changed, and your host might even be so courteous to increase the currently defined values of those abovementioned directives for you -- and that´s what I´m suggesting at this point.
Cheers
