Glad we finally got there on that.

As for writing back to the file the $_POST variable is really an array, so you can loop through the array and then write to file when you hit a key() value of name or location. This should sort you out nicely.

Have a go and if you get stuck post the code you've got and I'll have a play around with it.

u explian me how to do it...and i hve tht of this also...i wll use a count variable while reading and use name [count]=$str[0] and value[count] =$str[1] insie the while loop and as soon as we enter keep incrimenting count..
so tht its jst matter of for loop and implode in write function...

The $_POST[] is really an associative array so yo ucan simply loop through it and for any thing where the key() is either name or location you can write an appropriate line to te text file.

Try something like:
[php]
foreach($_POST as $lcItem)
{
if (key() == 'name')
{
// write a line to the file using file functions
}
if (key() == 'location'
{
// write a line to the file using file functions
}
}
[/php]


I have not tried this, I am typing this whilst I play with my 9month old daughter - so that's me done for the weekend, I'll check back on monday.

wht u hve said is 100% correct ..but i cannot hard code it ....bcos i wll be not knowing wht is in the file i wll be jst knowing tht there is a file and there are 2 strings seperated by ":" .....so i wll be not knowing tht it has name ,place or something else...so i cannot use if (key() == 'name')........i hve to dynamically read the names and write the content!!!!

Well in that case, the key() function can still be of use to you. You write to the file key(): $_POST[key()]. This should do the trick.

Based on this scant outline I would suggest that you need to investigate the directory functions in PHP. This would enable you to create an array of images. You could loop through this array using some sort of timer (note this example would need to be adapted to control when code is executed inside a loop).

I have never done anything like this, but this is how I would approach the problem.

My recommendation is to have a go with this, or any other bsae line idea. If you get stuck I would post your code and your problem to a new thread. This one has a lot of posts on it now and people may be put off by that so you could miss out on some better help.
