Dynamic Form Processing

How to process an unknow number of variables

[jbalestrieri]

I have a form which I wrote to write captions for graphics in a directory.

The form counts the files in the directory and creates the form field based on the number of files it finds. Here is a stripped down version of the form script.

while ( list( $key, $fileName ) = each( $images ) )
{
if(!empty($fileName) )
{
echo " <td align=\"CENTER\" valign=\"TOP\"><IMG SRC=\"$path/$fileName\" border=0 alt=\"$count\"";
if (!empty($thumb_width)) {echo " width=\"$thumb_width\"";}
if (!empty($thumb_height)) {echo " height=\"$thumb_height\"";}
echo "></a><input name=\"graphic$count\" type=\"text\" value=\"$fileName;\"readonly=\"readonly\">&nbsp;&nbsp;<input type=\"text\"";
echo "name=\"cap$count\"><br>";
if ($count == $break) {
echo "\n </td>\n</tr>\n<tr>\n";
$break = $count + $colunas;
}
else { echo "</td>\n"; }
}
$count++;
}

}
The form that writes the information formats and writes the data to a file.
$input = "$graphic1$cap1\n$graphic2$cap2\n$graphic3$cap3\n$graphic4$cap4\n";

This method works great if there are only 4 pictures, my problem is I do not know how many graphics there will be. Is there a better way to capture the data from this type of dynamic form and format it for writing?

Count the number of files in the directory, and then loop the db entry routine ->

Count.files

Loop while < count.files
=Add to db=

The form data is passed to another script for processing, how do I do this in this case? Also I do not write to a data base but write the input to a flat file. So I'm not sure how I would do this.

OkI was just being an idiot. I loaded everything into an array and the did a count and it worked. Sorry for being so stupid...
