PHP Photo Album script v2.0 help

[Yaz]

I was wondering how in the PHP Photo Album script v2.0 script if I can modify it to use the file names of the pictures as the photo description. I want to parse out the extension in the file names and simply use the names for all the photo descriptions. I looked at the php file and I know the file names are passed and I think the file is gets these paths and file names, but I can't seem to figure out how to parse them and assign them to the auto-generated description.

The DD files are located at http://www.dynamicdrive.com/dynamici...photoalbum.htm

Thanks for your help

Sure. This is untested, but should work. Inside ddphpalbum.js, find the lines below, and add to it the line in red:

		var desc=(desc && desc!="")? '<br />' + desc.replace(/(%i)|(%d)|(%s)/g, function(m){
				return (m=="%i")? i+1 : (m=="%d")? albumvar.images[i][2] : ""
			}) : ''
		desc=(desc=="%filename")? albumvar.images[i][1].split('.')[0] : desc

Then, for a particular album, if you want the description to just be the filename of each image, inside its invocation code, do the following:

new phpimagealbum({
	albumvar: myvacation, //ID of photo album to display (based on getpics.php?id=xxx)
	dimensions: [3,2],
	sortby: ["file", "asc"], //["file" or "date", "asc" or "desc"]
	autodesc: "%filename", //Auto add a description beneath each picture? (use keyword %i for image position, %d for image date)
	showsourceorder: true, //Show source order of each picture? (helpful during set up stage)
	onphotoclick:function(thumbref, thumbindex, thumbfilename){
		thumbnailviewer.loadimage(thumbref.src, "fit2screen")
	}
})

I have added the first if statment that is commented out at the beg of this function (this is only a partial copy of the function). the rest is the original code. I think it is getting the desc array values from the html file that is calling this function. I wanted to override the values and insert the name of the image. I put an alert on this.albumvar.images[i][1] so I know this is where the file name is housed. I want to take this and use it as the desc but get an error that says phpimagealbum is undefined. Please any suggestions would be appreciated.

function phpimagealbum(setting)
{
this.albumvar=setting.albumvar
for (var i=0; i<this.albumvar.images.length; i++){


//if (this.albumvar.images[i][1])
//{
//this.albumvar.desc[i]= this.albumvar.images[i][1]
//}else
//this.albumvar.desc[i]="no name found"
// }
if (this.albumvar.desc[i]) //if a manual desc exists for this image
this.albumvar.images[i][3]=this.albumvar.desc[i] //extend image array with desc
}

ddamin,
Thank you I will try it.

ddadmin,
I get "%filename" for each picture. If I only have one album do I leave autodesc: an empty string in the html file?

[ddadmin]

No, autodesc should be set to "%filename". Anyhow, I just realized an error in my code above. The line in red should read the following instead:

		var desc=(desc && desc!="")? '<br />' + desc.replace(/(%i)|(%d)|(%s)/g, function(m){
				return (m=="%i")? i+1 : (m=="%d")? albumvar.images[i][2] : ""
			}) : ''
		desc=(desc.indexOf('%filename')!=-1)? albumvar.images[i][1].split('.')[0] : desc

Thanks that worked I concatenated the break.

I have a related question. After making the updates listed in this thread I notice that some of the filenames are a little longer than the images and end up pushing the images to the right. Is there a way to do a character wrap for the file names?

[ddadmin]

If you mean trim the filenames if they exceed a certain length, you can try:

desc=(desc.indexOf('%filename')!=-1)? albumvar.images[i][1].split('.')[0].substring(0, 10) : desc

where 10 means the first 10 characters.

[james438]

I was thinking more along the lines of a character wrap, but I like your suggestion more because it helps to avoid vertical pushdown of the second or third row.
