| 36 | * Specific UploadPolicy for the coppermine picture gallery. It is based on the |
---|
| 37 | * PictureUploadPolicy, and some specific part to add the uploaded pictures to a |
---|
| 38 | * coppermine existing album. <BR> |
---|
| 39 | * Specific features for this policy are: |
---|
| 40 | * <UL> |
---|
| 41 | * <LI>Album handling : the setProperty("albumId", n) can be called from |
---|
| 42 | * javascript, when the user selects another album (with n is the numeric id for |
---|
| 43 | * the selected album). This needs that the MAYSCRIPT HTML parameter is set, in |
---|
| 44 | * the APPLET tag (see the example below). The upload can not start if the user |
---|
| 45 | * didn't first select an album. |
---|
| 46 | * <LI>If an error occurs, the applet asks the user if he wants to send a mail |
---|
| 47 | * to the webmaster. If he answered yes, the full debug output is submitted to |
---|
| 48 | * the URL pointed by urlToSendErrorTo. This URL should send a mail to the |
---|
| 49 | * manager of the Coppermine galery. |
---|
| 50 | * </UL> |
---|
| 51 | * <A NAME="example1"> <H3>Call of the applet from a php script in coppermine</H3> |
