Hello,

I have a script that uploads photos to a directory. I am trying to rename the file on the fly with an incrementing value, i.e. 0001.jpg, 0002.jpg. I can not figure out for the life of me how to do it. Usually I would use rand(), but I need the file name to increase incrementally, preferably with the date prefixed. The code I have now just outputs a file named "11.png" every time. Can anyone point out what the problem is? Maybe a solution, also... Thanks!

PHP Code:

$file_name=date('m-d-y');
$file_int=$file_name + 1;
$image_name=$file_int.'.'.$extension;
$newname="images/".$image_name; 


Basically, your code could look like this:

PHP Code:

$index=yourFunctionToGetTheCurrentValue();

$file_name=date('m-d-y');
$file_int=$file_name.'_'.$index;
$image_name=$file_int.'.'.$extension;
$newname="images/".$image_name;

yourFunctionToWriteDownTheNewValue($index+1); 


You could store the current value in an extern file for example. yourFunctionToGetTheCurrentValue() would be a function that opens this extern file and reads this value.

Date returns a string, not a number.

PHP Code:

$file_int=$file_name + 1; //invalid 


The best approach would probably be to store the current count somewhere and increment it every time you add an image:

PHP Code:

$count; //the current image count
$filename = 'images/' . date('m-d-y') . $count . '.' .$extension;
$count++;
//store the new value of count 


You'll have to figure out how to store $count.

Hello,
The solution that Trey Walter gived to you is a good one. The rest of the problem with the yourFunctionToGetTheCurrentValue() can be found here:

In order for this to work you will have either to put the date after the index number or to format the date in an alphabetical incrementing way ( y/m/d ).
