You can always use the ValidateServerFunction parameter to specify the name of a callback function that will make a database query to see if ise there any user name with the value passed to that function. If there is a record with that user name return 0 and the class will set the respective input field as invalid. I'm trying to create that for a few hours. Can you PLS give me an example? -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Re: [PHP] High bandwidth application tips
Radu Manole wrote: Hi all, I do have a question about optimizing the php for large applications. Many applications group the functions in files (eg. functions.inc.php) or build classes, and these files/classes are called with 'require' or 'include' on the top of each main file. What would be the speed penalty if we have to include many files or if these functions containter files are over 100k in size. I know the php engine will parse them too. Are any tips to follow when using many functions? It is much better to include only one big file, but only if you need all of that functions. You should try to separate your functions into 3 or + files: LoginFunctions.php, OtherFunctions.php, PictureFunctions.php and include only the ONE you need. If you need all of them, make only one file, and include only one file. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
