Hi guys, It's a simple question really (just getting used to php - actionscript 3.0 developer!) but I need to know how I can pass a CSS class into the arguments in a PHP function, then have it apply that style to text in html. What I have so far is: <?php function addText($text,$class) { ?> <div class= $class > <p><?php echo $text ?></p> </div> <?php } ?> But it doesn't work, the <div class = $class > should be different I think. Anybody got a solution?

I have a class for building forms and I want to upgrade it to handle Bootstrap. I'd like to use my current methods to build the Bootstrap elements, but I don't want all of this new Bootstrap code cluttering up my current Forms class, so I'd like to put it into its own class in a separate file. Below is a very simple example of what I'm trying to do. Obviously this doesn't work and the code is wrong, however, from this you can hopefully see what I'm trying to accomplish. <?php class Forms { public function input_text($name) { return '<input type="text" name="'.$name.'">'; } } class Bootstrap { public function bootstrap_input_text($name) { $return = '<div class="control-group">'; $return .= '<label class="control-label" for="'.$name.'">First name</label>'; $return .= '<div class="controls">'; $return .= $this->Forms->input_text($name); $return .= '</div>'; $return .= '</div>'; return $return; } } $form = new Forms(); echo $form->bootstrap_input_text('fname');

Hello, I am brand new to this forum so I am not sure if I am posting in the right place but I will give it a shot: I have been making PHP Classes for a while and thinking about giving away/selling them. I currently have a Flat file database Class that allows you to turn a text file into a table within a database. The queries are easy for example: select('FROM users WHERE username=hello');. This Flatfile Database contains many of the same functions as mysql. I decided to make this as i see mysql is being discontinued in the next version of PHP. Another class i have created is a login class. Setup is easy of course, all you have to do it simply include the main file(all in a folder called Login) and then wherever you want it simple past this code: new gLogin();. TADA you have a login. Please post any questions, concerns, or requests for new classes. Thank you, gamble

I really cannot understand it, I've tried several different ways of writing it that I'm sure I've used before, and I simply cannot get :hover to work with any of my divs... html: <a href=''><div id='menu' class='button1'></div></a> <a href=''><div id='menu' class='button2'></div></a> <a href=''><div id='menu' class='button3'></div></a> <a href=''><div id='menu' class='button4'></div></a> css: #menu { width:75px; height:75px; background-color:red; /* background-image:url('menu.jpg'); */ float:left; margin:20px; } .button1:hover { /* background-position:75px 75px; */ background-color:yellow; } as you can see I've commented out the image, ultimately I want the image to appear, but for now I can't get the :hover to change the state of the div at all, no reaction... any help would be much appreciated, its really frustrating me...

I'm fairly new to object orientated PHP and I was trying to think of a better way to connect to a MySQLi database within classes and functions, instead of just putting down an include everywhere. So far I came up with this: database.php <?php class database { protected $db_name = 'database'; protected $db_user = 'root'; protected $db_password = 'password'; protected $db_host = 'localhost'; function __construct(){ $this->connect(); } public function connect(){ $this->db = new mysqli($this->db_host, $this->db_user, $this->db_password, $this->db_name); } } $db = new database; ?> test.php class test{ private function getDb(){ include("database.php"); return $db; } public function test1(){ $find = $this->getDb()->db->query("SELECT * FROM user"); $rows = $find->num_rows; return $rows; } } and then just putting echo $test->test1(); on my page. I did have other functions inside the database class, but I've since scrapped those, so it just looks like that atm. It does work... however, I'm not sure how good or bad it is. In particular the first line in the test1() function. I have a feeling its a terrible way to do it... Or is it fine? like efficiency wise etc? before I would just use an include within every function. so I'd just do: $db->query(" "); Eventually I will have a few classes like user, etc, and these would all need to manipulate the database. So I was just thinking of plopping the getDb() function at the top of each of them and just include the database stuff... I tried looking at how phpBB and wordpress handle databases, but theirs are just full of unnecessary stuff for me and its just difficult to decipher. They use a global I think?

Long ago I started with a php function that generated an html select list from a mysql table. Over time, I've needed versions that did various things differently (two fields displayed between the <option> and </option> or a div displayed based on the selected value) so I've kept building new versions. Every time I build a new version I think "boy I should make a class and extend it to do things the new way" but I never have and now I must have half a dozen versions of the code. Today I sat down and started coding my class and quickly realized that I need to actually figure out what I put in the parent class and where I draw the line and create another class based on the first. Mostly I code procedural and I could really use some help thinking this through. Here's what I have in terms of permutations that I want to accomplish: Build an SQL select set a where clause set an order by select multiple columns to concatenate as labels (for example: <option citycode='$cid'>$city, $state, $country</option> ) Build html Allow list to start with value ='' (eg <option value=''>Choose a state</option> <option value='AK'>Alaska...) set a selected= value (or values for multiples) <div> s No <div> display Display of a <div> if other is selected input type=text textarea Display of a <div> for each value seected Types Select list single or multiple Radio checkboxes So, do I create a class with methods for each type of html list and a child class for the divs? A parent with the divs and children where I override the method that created the html for radio and checkboxes, something else entirely? Thanks, David

Hi everybody, I am currently working with the php_serial.class to send out signals through the serial port of my computer. I set up a webserver on Windows with Apache and its working fine. The only problem is, that when I press the button on the homepage, it takes like 6 seconds to actually send something out the port. You guys have any ideas why this could be happening? I tested under Windows 7 and XP with the newest version of Apache Server and several different computers with different hardware. Always the same results.

I have a simple category table in which 5 or 6 names are there. Now I want to retrieve them. When I connect to mysql database in procedural way, the while loop is working great, giving nice output. But when I go through a class and trying to retrieve the data, it stops after giving the first table name. My procedural code is here: mysql_connect("localhost", "root", ""); mysql_selectdb("12reach"); $cat = mysql_query("SELECT * FROM `category` LIMIT 0 , 30"); if (!$cat){ die ('Error'); } while ($row = mysql_fetch_array($cat)) { extract($row); echo $row['name'].'<br>'; } It works fine. Giving six category name. But problem begins with the following code: I have two classes and a php file where I created an instance of category class and trying to get the category table names one by one. class ConnectClass { private $_connection; public function getConnect() { $this->_connection = mysql_connect("localhost", "root", ""); if (mysql_errno()) { throw new RuntimeException('Cannot access database: '.mysql_error()); } else { mysql_selectdb("12reach", $this->_connection); } } include 'ConnectClass.php'; class CatClass extends ConnectClass{ public function getcat() { $cat = mysql_query("SELECT * FROM `category` LIMIT 0 , 30"); if (!$cat){ die ('Error'); } while ($row = mysql_fetch_array($cat)) { extract($row); return $row['name'].'<br>'; } } } include 'CatClass.php'; $obj=new CatClass(); $obj->getConnect(); echo $obj->getcat(); Probably while loop is working inside the class. As I want to return the last name of the category table, I can get it placing it outside the loop. But if I want the full name list, it does not work in object oriented format. Any idea, where is my fault?

Good afternoon everyone, and happy holidays! Although my membership might not qualify as "new" to this forum, I've never used my account here before but today I think I finally found a reason to!

Therefore, I cannot simply exclude array keys [1], [2], [17], [18] Here's the code I'm working with now: <div id="depapttab"> <p>Select your departure airport:</p> <select id="depicao" name="depicao"> <option value="">Select All</option> <?php if(!$depairports) $depairports = array(); foreach($depairports as $airport) { if($depairports->id != array(13,18,19,22)) { echo '<option value="'.$airport->icao.'">'.$airport->icao.' - '.$airport->name.'</option>'; } } ?> </select> <input type="submit" name="submit" value="Find Flights" /> </div> I just don't know how to include that darn stdClass Object() in my if() statement. If someone could lend a hand, it'd be much appreciated! Thanks in advance!

Hello: Any suggestions how to use all variables of a methods inside an array to apply another method on each one? fuction fn0(){....}//end fn0 function fn1($x1,$x2,$x3,$x4){ $mAr=array($x1,$x2,$x3,$x4); foreach($mAr as $val){ $this->fn0($val); }//end foreach }//end fn1 In reality I have like $x12. Thanks.

I am using parent::__construct() in almost every classes to connect Mysql DB. Example class class secondClass extends dbconnect { public function __construct() { parent::__construct(); dbconnect class class dbconnect { private $mysqli_handler; public function __construct() { try { mysqli_report(MYSQLI_REPORT_STRICT); $this->mysqli_handler = mysqli_connect(DB_HOSTNAME, DB_USERNAME, DB_PASSWORD, DB_DBNAME); } catch (mysqli_sql_exception $e) { throw new Exception('Error: Could not make a database link using ' . DB_USERNAME . '@' . DB_HOSTNAME . '!'); } if ($this->mysqli_handler->connect_error) { trigger_error('Error: Could not make a database link (' . $this->mysqli_handler->connect_errno . ') ' . $this->mysqli_handler->connect_error); } $this->mysqli_handler->query("SET NAMES 'utf8'"); $this->mysqli_handler->query("SET CHARACTER SET utf8"); $this->mysqli_handler->query("SET CHARACTER_SET_CONNECTION=utf8"); $this->mysqli_handler->query("SET SQL_MODE = ''"); $this->mysqli_handler->query("SET time_zone = 'Asia/Kolkata'"); } Is this create multiple instance of mysql dbconnection? I am frequently getting mysql connection error on my shared hosting. If so how to avoid? I am using PHP Version 7.4.16, some detailed explanation will be useful for me as I am using like this for many projects. Thank you for your time. Prabakaran
