  • Define a class dynamically?

    - by Pekka
    Is there a way to dynamically and conditionally create a class definition in PHP, i.e. if (condition matches) include file containing class definition else class myclass extends ancestor_class { .................... } without eval()? My background is the accepted answer to this question. I am looking for the best way to build a untouchable core library, with user-defined empty classes extending the core library if necessary. I want to create the final class definition "on the fly" if there is no user-defined empty class for a certain ancestor class.

    - by Idealflip
    Hello all! Quick question I originally had a submit button. <input class="submit" type="submit" class="input" value="Add" name="command" /> but now I would like to use a instead.

Issue is, the site is not picking up that this specific was clicked, and therefore won't run my php code.

  • How to document a Symfony based REST API (similar to enunciate's documentation capabilities)

    - by Dominic
    If I have a REST based service written in the Symfony [symfony-project.org] framework (i.e. PHP), is there any decent tools/frameworks out there that will parse my code and generate API documentation? The Java based framework enunciate has documentation capabilities similar to what I need, you can view an example of this here: http://enunciate.codehaus.org/wannabecool/step1/index.html. I understand the premise of REST based services are supposed to be self evident, however I was after something that would generate this documentation for me without the need to manually write up all my endpoints, supported formats, sample output etc. Thanks

  • Sending passwords over the web

    - by Falmarri
    So I'm working on a mobile platform application that I'd like to have users authenticate over the web. I was wondering the best way to do security. The user is sending a password for HTTP to a php server wich authenticates against a mysql database on the same server. Obviously I don't want to send the password in plain text over the internet, but I also don't want to do 2 SHA hashes. This is what the server looks like (in pseudocode) $pass = $_POST['pass']; if ((get PASSWORD where USERNAME = USERNAME) == SHA($pass)) return PASS; This is pretty standard and I don't think there's any other way to do this. But I was wondering how I should prepare the data before sending it over the internet.

  • Displaying objects based on if a user is logged in or not

    - by MaxMackie
    I'm learning about PHP sessions for user authentication on my website. I know how to restrict the viewing of a complete page using sessions (simply check if the 'uid' session variable is set and if it is, show content, if not redirect to an error). However I'm trying to figure out the best way to selectively show and hide different objects (div, text, images) based on if a user is logged in or not. Is it as simple as checking for the 'uid' session variable and displaying based on if it set or not? Is there a more efficient way of doing this id there are a lot of conditional elements on a page?

  • How to make a page print to printer just once

    - by menislici
    I have a basic html page generated through php and it prints to a printer after a link click using Ben Nadel's print plugin. However, I don't want the user to print the page again. I tried setting the 'print' link to a negative z-index using jquery after it's being clicked, but the user can refresh the page and reuse the link so it would print again. I also know that I can somehow disable the refresh feature, by modifying what F5 does, but that would't save the day since the user can refresh the page through the url bar, and I can't remove/hide, it as much as I know. It also runs on localhost so the user client and server are on the same side. Even the browser doesn't matter since I could use the one that fits this case.

  • How to set the session timeout in Zend Framework 2

    - by user2261761
    I don't have much Zend experience and want to change someone's login code in Zend to make the session not expire. It seems the code is basic behavior: $adapter = $this->getAuthService()->getAdapter(); $adapter->setIdentity($email)->setCredential($password); $result = $this->getAuthService()->authenticate(); What do I have to do to make the session not expire or to at least set the session for a specific time? Right now the user doesn't stay logged in for long, I think perhaps it is just relying on default php settings behavior like the standard 24 minutes for the gc_maxlifetime. What is the connection between Zend_Session and AuthService?

  • Why doesn't MySQL support millisecond / microsecond precision?

    - by Byron Whitlock
    So I just found the most frustrating bug ever in MySQL. Apparently the TIMESTAMP field, and supporting functions do not support any greater precision than seconds!? So I am using PHP and Doctrine, and I really need those microseconds (I am using the actAs: [Timestampable] property). I found a that I can use a BIGINT field to store the values. But will doctrine add the milliseconds? I think it just assigns NOW() to the field. I am also worried the date manipulation functions (in SQL) sprinkled through the code will break. I also saw something about compiling a UDF extension. This is not an acceptable because I or a future maintainer will upgrade and poof, change gone. Has anyone found a suitable workaround?

  • Zend Framework Relations vs. Table Select

    - by rtmilker
    Hey! I just want to know your guys opinion on using join tables within the zend framework. Of course you can use relations by defining a referenceMap and dependentTables and stuff, or using setIntegrityCheck(false) within a db select(). The setIntegrityCheck version seems a little bit dirty to me, but the other version is not very suitable for big querys and joining many tables... I'm a PHP developer for 5 years now and new to the zend framework and just want get a direction for my first project. Thanks!!!

  • Joomla article not showing in the frontend but its visible in administrative part.

    - by user248674
    I have a very big article to be put into our joomla site. At first I was getting "Fatal error: Allowed memory size of 8388608 bytes exhausted (tried to allocate 285487 bytes) in..." . But then I increased the memory_limit in php.ini . And I was able to create the article. Now I can view the article by logging into backend. But the article is not at all visible in the front end. If I click on the menu item pointing to that article, all I can see is a blank page with nothing in it. All other articles in the site are visible properly. Any idea? ps: I have enabled the error reporting to maximum, also ran the site in debugging mode. But saw nothing unusual.

    I have searched this site and Google and even though the idea is pretty simple I can't figure it out. I need to (like seen on YouTube) calculate the % of up-votes based on the amount up-votes and down-votes. I have two vars, $upvotes and $downvotes now i need to calculate $ratio For example $upvotes = 3; $downvotes = 1; The ratio here needs to be 75 (%) If you have $upvotes = 0; $downvotes = 100; It needs to be 0 (%) How do I calculate the percentage (in PHP)?

  • Test/expand my email regex

    - by Ross
    I'm really not confident with Regex, I know some basic syntax but not enough to keep me happy. I'm trying to build a regular expression to check if an email is valid. So far here's what I've got: [A-Za-z0-9._-]+@[A-Za-z0-9]+.[A-Za-z.]+ It needs to take account of periods in the username/domain and I think it works with multiple TLDs (e.g. co.uk). I'm working with the preg engine in PHP so it needs to work with that. Thanks if you can help!

  • What's the difference between /123 and /?123?

    - by BoltClock
    I've noticed that some sites (including http://jobs.stackoverflow.com) have query strings that look like this: http://somewebapp.example/?123 as compared to: http://somewebapp.example/123 or http://somewebapp.example/id/123 What are the reasons that developers choose to implement their web apps' URLs using the first example instead of the second and third examples? And as a bonus, how would one implement the first example in PHP, given that 123 is the primary key of some row in a database table? (I just need to know how to retrieve 123 from the URL; I already know how to query the database for a primary key of 123.)

  • PHPUnit doesn't recognize file_exists()

    - by Ondrej Slinták
    I've set up a project with unit test files in NetBeans. I set bootstrap to C:\www\foo\_tests\TestAutoload.php and put simple autoload method to this file: function __autoload( $class_name ) { // series of ifs if ( ... ) { $file_name = ... } if ( file_exists ( $file_name ) ) { require_once( $file_name ); } else { echo "autoload error"; } } All of my tests fail on autoload this way. They always output just "autoload error". If I don't check if file_exists and just use require_once( $file ) no matter what's in $file, it works perfectly. Anyone encountered anything like this before? It's not something I couldn't resolve by simply not checking whether file exists or not, but I'm interested why it does this and if I can cheat it somehow.

  • Advice needed for a small web application's architecture/implementation

    - by Johhny P
    I was asked to build a website where a company's employees (around 20) could login and fill in their working schedules for a present and past (if needed) month. Employees should ofcourse only be able to see their own schedules, but the manager should have the privilege to access every schedule. I have little experience in web development therefore an advice is needed. I have already created a PHP/MySql login page. Now what? How do I go about it? Just some architectural or implementational(if you will) guidance would be really appreciated.

  • is there a way to show what field you updated in mysql?

    - by ggfan
    When users edit their account, I want to display a confirmation page that shows their updated information with the fields that they changed in bold. Is there a mysql statement that allows you to select the fields that a user changes? If not, how exactly can I achieve this Ex: (editaccount.php) first_name: bob last_name: builder email: [email protected] When they change say their first name to "james", the confirmation page shows their first name in bold because they changed that but the other areas are still normal text. first_name: <b>James</b> last_name: builder email: [email protected]

  • What's the right way to handle "One, Both, or None" logic?

    - by Stephen
    I have a logic situation that is best described as two "Teams" trying to win a task. The outcome of this task could be a single winner, a tie (draw), or no winner (stalemate). Currently, I'm using a nested if/else statement like so: // using PHP, but the concept seems language agnostic. if ($team_a->win()) { if ($team_b->win()) { // this is a draw } else { // team_a is the winner } } else { if ($team_b->win()) { // team_b is the winner } else { // This is a stalemate, no winner. } } This seems rather spaghetti-like and repetitive. Is there a more logical, DRY pattern I could use?
