You need to give mysql_select_db() the actual name of your database, i.e. mydomain_test1. When you've created the database then you can have as many tables as you would like inside that database. Seeing as you have a curious way of using punctuation and spacing I don't think that will be possible

NOW() is a MySQL function and not a PHP function. You must use it inside the query like toplay explained.

There is no point in having an ORDER BY if you limit it to one row.

I wish I had your design skills. It looks awesome.

@dsaba: All URLs does not need at least one dot. E.g. from within my LAN my computer will be accessible by the name daniel-laptop. That means that http://daniel-laptop will be a valid URL from within my LAN seeing as my computer is running an httpd on port 80.

Try to change if(filemtime($cache_file) + 1*60 > time()) to if(filemtime($cache_file) - 1*60 > time() || !file_exists($cache_file)) Then delete cache/menu.html and try again.

Could you post the code you have?

Just spotted an error in the class. Updated: <?php class Cache { static protected $cache_dir; protected $contents; protected $path; public function __construct($filename) { $this->path = self::$cache_dir . $filename; if(!file_exists($filename)) { throw new Exception("Cache file '{$filename}' could not be found"); return false; } $this->contents = file_get_contents($this->path); } public function isOlderThan($seconds) { return filemtime($this->path) + $seconds < time(); } public function update($new_content) { $this->contents = $new_content; file_put_contents($this->path, $this->contents); } public function getContents() { return $this->contents; } public function __toString() { return $this->getContents(); } static public function setCacheDir($dir) { self::$$cache_dir = $dir; } } ?> Note: I have not tested this version or any other code I have posted in this topic.

Change it to: mysql_query ('INSERT INTO ' . $table . ' VALUES ( {$_REQUEST["Name"]}, {$_REQUEST["Info"]} );'); And then read this: http://php.net/string#language.types.string.parsing.complex

I feel generous so I decided to make the class: <?php class Cache { static protected $cache_dir; protected $contents; protected $path; public function __construct($filename) { $this->path = self::$cache_dir . $filename; if(!file_exists($filename)) { throw new Exception("Cache file '{$filename}' could not be found"); return false; } $this->contents = file_get_contents($this->path); } public function isOlderThan($seconds) { return filemtime($this->path) + 30*60 < time(); } public function update($new_content) { $this->contents = $new_content; file_put_contents($this->path, $this->contents); } public function getContents() { return $this->contents; } public function __toString() { return $this->getContents(); } static public function setCacheDir($dir) { self::$$cache_dir = $dir; } } // In another file: require_once 'library/Cache.php'; Cache::setCacheDir('/home/somebody/cache/'); // ... $cache = new Cache('menu.html'); if($cache->isOlderThan(30 * 60)) { // generate content and store in $menu_html $cache->update($menu_html); } else { $menu_html = $cache->getContents(); } ?>

You could do something like this: <?php $cache_file = 'cache/menu.html'; if(filemtime($cache_file) + 30*60 > time()) { // generate the content here and store it in $menu_html; file_put_contents($cache_file, $menu_html); } else { $menu_html = file_get_contents($cache_html); } ?> You might want to expand it and make it into a class so you can do this: <?php $cache = new Cache('menu.html'); if($cache->isOlderThan(30 * 60)) { // generate content and store in $menu_html $cache->update($menu_html); } else { $menu_html = $cache->getContents(); } ?>

In that case the query probably failed. Try running the query manually using e.g. the MySQL command line or GUI tools like phpMyAdmin and see what the result is.

1) You cannot know if you want to change something later. 2) The amount of saved space is negligible. 3) It takes longer to other people to read. I don't think it's worth nesting ternary operators.

You can do something as basic as this: <?php $file = '/home/somebody/the_file.txt'; if(!isset($_POST['content'])) { $content = file_get_contents($file); echo <<<EOF <h1>Edit file '{$file}'</h1> <form action='{$_SERVER['PHP_SELF']}' method='post'> <label for='content'>Content:</label><br /> <textarea name='content' id='content'>{$content}</textarea><br /> <input type='submit' value='submit' /> </form> EOF; } else { if(file_put_contents($file, $_POST['content'])) { echo 'The file was updated'; } else { echo 'The file could not be updated'; } } ?>

I'm not quite sure what you're trying to accomplish. Is it template files you wish to cache so they don't have to be parsed at every request?

Try to var_dump($wynik); and see what it outputs.

$_POST['dropdown'] or $_GET['dropdown'] depending on how you submit the form.

Instructions on writing some code written in the imperative mood strongly suggests that it is a task somebody else has assigned to you. Seeing as this is rather trivial it's most likely homework and this is not a "do my homework for me" website.

Not really, the file must already be on the server. To upload a file do this: http://www.php.net/manual/en/features.file-upload.php

Try to attach the file and let us take a look.

There are various ways you could do that. You could do a simple SELECT * FROM table WHERE field LIKE '%Simon%'; or you could take use of MySQL's full-text searching. Alternatively, you could use more advanced searching algorithms such as Zend Framework's implementation of Lucene: Zend_Search_Lucene. I suppose that you by searching mean "check if it contains".

Ah, didn't realize it was that. I haven't really used any pear libraries, but it's the same naming convention in Zend Framework which is the one I find best for PHP.

What kind of encryption do you want? PDF has built in support for encryption. Or do you want to encrypt it with e.g. PGP?

PHP Answer: No, but you can do it when they are uploaded.
