  • PHP - Get value of imput box, without a form?

    - by Dodi300
    Hello. Does anyone know how I can get the value of an imput box, without having a form? I want a sumbit button, but instead of submiting a form, I want it to change data in a MySQL database. Something like this maybe? $img1="WHAT DO I PUT HERE?" $idx=1 $sql="INSERT INTO games SET img1='$img1' WHERE id=$idx"; $result=mysql_query($sql); Could I use that code on a "onclick" event? The imput box is named "img1". Thanks for the help!

  • How to get the value of an attribute from XML file in PHP?

    - by Matt
    Hi, Sorry if this seems like an easy question, but I've started pulling hair out on this... I have a XML file which looks like this... <VAR VarNum="90"> <option>1</option> </VAR> I'm trying to get the VarNum. So far I've been successful using the follow code to get the other information: $xml=simplexml_load_file($file); $option=$xml->option; I just can't get VarNum (the attribute value I think?) Thanks!

  • PHP SQL, SELECT corresponding data from 3 tables at once?

    - by user346325
    I have 3 tables, 'u' 'd' 's' 'u' has userid divid 'd' has divid divname 's' has sname primaryuserid secondaryuserid Now what I'd like to do is display a table with rows of the following format userid, divname, sname Plus figure out a way to decipher whether userid is a primary or secondary for this sname table. I'm able to show userid and divname using a left join, but I don't know how I would add a third table? To make it trickier, there can be more than 1 snames for each userid, up to ~20. Is there a way to display 0-20 snames depending on the userid, seperated with commas?

  • SQL & PHP - Which is faster mysql_num_rows() or 'select count()'?

    - by Joel
    I'm just wondering which method is the most effective if I'm literally just wanting to get the number of rows in a table. $res = mysql_query("SELECT count(*) as `number` FROM `table1`"); $count = mysql_fetch_result($res,0,'number'); or $res = mysql_query("SELECT `ID` FROM `table1`"); $count = mysql_num_rows($res); Anyone done any decent testing on this?

  • PHP Passing Data to a Specific Class? (Data Encapsulation)

    - by Adam184
    I've learned that OOP is all about data encapsulation, but what about passing data between classes that have nothing to do with each other (would the below example be worthy of using extends)? class Dog { private $secretVar; public function getSecretVar() { $this->secretVar = 'psst... only for rainbow!'; return $this->secretVar; } } class Rainbow { public function __construct(Dog $Dog) { print_r($Dog->getSecretVar()); } } $Dog = new Dog(); $Rainbow = new Rainbow($Dog); // ... classes that don't need the $secretVar How would you encapsulate $secretVar for only classes Dog and Rainbow? As of now, anyone can call getSecretVar(), and I'm having a hard time allowing that to happen as it seems to defeat the whole point of encapsulation.

  • Desperate help using PHP's $_SERVER["DOCUMENT_ROOT"] on a web server?

    - by Nickersoft
    I've spent the past few months building a website on localhost. Throughout the site, instead of using relative paths, I used $_SERVER["DOCUMENT_ROOT"] to access the root of my server so I could reference files from there. However, I just decided to upload my site to 000webhost. As I soon found out, and for those of you who use them, you are probably aware, that their server root is different than your actual directory in which you upload your files. I believe it's virtual hosting... anyway, my $_SERVER["DOCUMENT_ROOT"] now throws errors along the lines of this on the site: Warning: include_once() [function.include-once]: open_basedir restriction in effect. File(/usr/local/apache/htdocs/mypath) is not within the allowed path(s) Every other site I looked at said that you should just replace $_SERVER["DOCUMENT_ROOT"] with the home directory provided to you by 000webhost. However, if I want to change hosting services in the future, I'm screwed. Is there any way to use $_SERVER to access a set virtual directory or use htaccess or something to make my code work? I tried using DocumentRoot in a htaccess file in my root directory, but it threw a 404 error when trying to access the page. I'm in desperate need... can anyone help me?

  • Mac Text Editor (with function list)

    - by Meep3D
    So I've got a Mac in the post coming to me, and will probably be doing quite a bit of development on it so I am looking for a text editor (PHP + HTML mainly). I curently use Notepad++ on Windows and I simply cannot live without the function list plugin (It displays all functions in the current PHP file in a box on the right). Do any Mac text editors have this functionality? I am fairly sure that Notepad++ isn't available on an Apple. Thanks!

  • How to set mod_rewrite in WAMP?

    - by Martin Jenseb
    I learn Symfony2 and i have: http://symfony.com/doc/current/quick_tour/the_big_picture.html http://localhost/Symfony/web/app.php/demo/hello/Fabien And if you use Apache with mod_rewrite enabled, you can even omit the app.php part of the URL: http://localhost/Symfony/web/demo/hello/Fabien Last but not least, on the production servers, you should point your web root directory to the web/ directory to secure your installation and have an even better looking URL: http://localhost/demo/hello/Fabien how can i make this in WAMP Server?

  • Is there another way to run Apache2 securely for end users without using CGI mode?

    - by Volomike
    Is there another way to run Apache2 securely for multiple end users (like hosting hundreds of blogs) without using CGI mode as required by suPHP? It just seems so inefficient to use CGI mode for PHP when if we could set up permissions properly, we could host PHP through mod_php perhaps? I mean, I do want to restrict these users to their home directories for their sites, but don't want any security issues.

  • Could you share your emacs dot-files for web development

    - by Gok Demir
    Hi, could you kindly share your emacs dot-files for web development that works with CSS, HTML, JavaScript, PHP and if possible with Python Django. I really need complete setup. I looked nXhtml and its good on some parts (html code completion works but sucks on indentation and CSS code completion does not work and says tag table is empty most cases. I really need something that works: code completion works out of the box, git integration and pretty indentation and supports multi-mode for mixed HTML, CSS, JavaScript, PHP code.
