How big is the HTML 'hidden' field?

<< < (2/2)

housetier:
md5 does not have a limit of the input data. That is what I meant with "regardless of input size": no matter how much or how little data you provide as input, you always get a result that is 128 bits long.

I strongly suggest you upgrade to php5. If you deal with such large amounts of data, php5 will be much better.

barney:
OK,

I have a workaround.  Add another textarea with DISPLAY:none.  Not wild about it, but should be functional.  Still like to know those upper limits, though <sigh />.

barney:
I'd love it if PHP5 were available, but I have to work within the limits of the client's hosting.  According to her, the host has no immediate plans to upgrade PHP.  Caution when upgrading is understandable, but this seems a bit extreme.  Oh, well ... who am I to say?

Anyway, thanks for the help.  Now I have belt and suspenders <chortle />.
