the same principles apply to many things, but here's an idea. building blogs is relatively straightforward, but can appear tricky if youre new to PHP. what information do you want for each blog entry? you need to think about content, such as the title, main text, date/time, user id (if youre not the only person posting), pictures, etc. the blog i use only has these 5 fields in my MySQL database: id - the record key public - this is set to y or n, and determines whether it's just a saved entry or whether it has been published. date - a timestamp of when the blog entry was created title - simple title for the blog entry entry - the text that makes up the main blog entry. of course, you could also use a plain text file or even a XML file if you know much about them instead of a mysql db. the principles are very similar with each. in some ways too, using a text file or a XML-type file would be easier than also having to learn MySQL. once you've planned how youre going to store the data, the whole process of putting the blog together is fairly straightforward. if you're using MySQL, then ANY mysql tutorial will get you the basics you need, including using SELECT/ORDER BY (for getting blog records to be displayed), INSERT (for creating new entries) and UPDATE (for editing existing entries). you don't need to go any further than that for now. once you've got the grasp of that, all you need to do (in HTML) is design a 'container' where a single blog entry will go. wrap it in a PHP 'while' loop to read all of your SELECTed entries from the database, using the 'echo' function to display the information you've read from a blog entry. ok, i've not gone as far as posting the code for you, but if you can get a clear idea of what you need and how it should look, the amount of PHP you need to get the whole job done is very minimal. hope that helps a bit, Mark [b]edit[/b]: i do have bits and bobs of a simple blog script i use (have a look at it working here [a href=\"http://www.crashandburn.co.uk/blog.php\" target=\"_blank\"]http://www.crashandburn.co.uk/blog.php[/a] and here [a href=\"http://www.thedinnertimes.com/columns/\" target=\"_blank\"]http://www.thedinnertimes.com/columns/[/a] ). youre welcome to have the scripts to have a look although for the sake of getting to grips with things and figuring it out, youre better have a bash at it yourself. if you want them tho, just drop me a PM.

[/quote] i'd say PHPfreaks is an odd place to come if you wanna learn C/C++, but: 1, [b]How long does it take to learn C[/b] - depends if you have any prior knowledge of programming. the most difficult thing for people to grasp it seems is the process that a program goes through to get things done. ontop of that, it's about understanding what you want to do and learning the functions to do it. C++ was taught to me to a pretty good level in a 2 year, 2 hours a week college course. 2, [b]Is C+ still around? [/b] if it's the same as C++, then yes. 3, [b]What is C++ used for?[/b] programs. both games and applications. Doom/Quake etc are written in C++ as are many web servers/packages/browsers.

[/b] you can safely knock up entire apps with C++ alone. Most C++ packages i've used actually support inline Assembly (allowing you to stick assembly language right into the code) but this is fairly unnecessary in the first instance. only when it comes to having a severe need for speed is assembly necessary, as C++ is a fairly low level language itself. 6, [b]Is there basic tutorials as beginners to advanced[/b]Google is your friend [b]or do i need to buy books?[/b] reading is good too.

hi the error would be occuring as you have no check in the event that the picture is NEITHER format. add an extra trap to cater for the event that the picture is not of any valid format. cheers Mark [b]edit:[/b]also, this bit wont work anyway as far as i know: [code] @imagecreate($filename); [/code]as 'imagecreate' requires a width/height, not a filename.

hmmm i tried your function out, as well as using strings, etc with mktime and couldnt reproduce your error. - what version of php are you using? - what is the level of error_reporting you have in your php.ini? you can find out with this if youre unsure: [code] echo ini_get('error_reporting'); [/code] apart from the warning, does the function still do its job? i think there's a function to force a datatype onto a variable, but not sure - you can use this though to force a numeric string into an integer - just add zero: [code] $number = "12345"; $now_numeric = $number + 0; [/code] [b]edit:[/b] function for forcing integer is 'intval' [code] $number = "12345"; $now_numeric = intval($number); [/code] hope that helps Cheers Mark
