PHP - Is This The Correct Approach?

So, I'm starting a new project and thought I would try a new approach at loading files and classes to process output.  I think my logic is correct, but for some reason I'm getting a blank page.  Basically instead of having seperate pages to output different functions and such, I store everything in one page.  It's the same deal as the switch case approach, but it uses a foreach loop to cycle through the actions, classes, and functions which are stored in an array.

Here's my index.php file:
Code: [Select]
<?php

require('config.php');
include('languages/english.php');
include('classes/Template.php');

$template = new Template;

$viewPages = array( 
'category' => array('classfile' => 'Category.php', 'classname' => 'category', 'functions' => array('create', 'delete', 'modify', 'merge')),
'questions' => array('classfile' => 'Question.php', 'classname' => 'Question', 'functions' => array('create', 'delete', 'modify', 'votegood', 'votebad'))
);


$currentPage = $_REQUEST['action'];

foreach($viewPages as $action => $settings){

if($currentPage == $action){
require(INCLUDE_ROOT.'/classes/'.$settings['classfile']);

$class = new $settings['classname'];
$function = $_REQUEST['do'];
$class->$function();

$template->loadTemplate($settings['classname']->viewFile, $vars = array());
if($template->message == FALSE){
die($template->message);
}

}

}

?>
Here's the Template class file:
Code: [Select]
<?php

class Template {

var $file;
var $vars;
var $message;

function loadTemplate($file, $vars){

if(empty($file) || empty($vars)){
$this->message = LANG_ERR_7;
} else if($file = file_get_contents(INCLUDE_ROOT.'/'.$file)){
$this->message = LANG_ERR_7;
} else {
foreach($vars as $key => $val)
$file = str_replace('{'.$key.'}', $val, $file);
}

$this->message = FALSE;
return $file;

}

}

?>
I tried visiting the category action(index.php?action=category;do=create).  This is the classfile for that
Code: [Select]
<?php

class category {

var $id;
var $title;
var $description;
var $uri;
var $message = array();
var $vars = array();
var $viewFile = '';

function create(){

if($_POST['submit']){

//Review the user input and make ure everything is ok
$messages = array();
if($this->title == FALSE){
$messages['title'] = LANG_ERR_1;
} else if(strlen($this->title) > 30 || strlen($this->title < 5)){
$messages['title'] = LANG_ERR_2;
} else if($this->description == FALSE){
$messages['description'] = LANG_ERR_3;
} else if(strlen($this->description) > 400 || strlen($this->description) < 10){
$messages['description'] = LANG_ERR_4;
} else {
$messages = FALSE;
}

if($messages != FALSE){
$this->messages = $messages;
$this->viewFile = INCLUDE_ROOT.'/template/index_body.tpl';
} else {
$this->title = htmlentities($this->title);
$this->title = stripslashes($this->title);
$this->title = htmlspecialchars($this->title);

$this->description = htmlentities($this->description);
$this->description = htmlspecialchars($this->description);
$this->description = nl2br($this->description);

$query = "
INSERT INTO categories
(c_title, c_desc)
VALUES('".$this->title."', '".$this->desscription."')";

if(mysql_query($query)){
$this->message['succes'] = LANG_ERR_5;
} else {
$this->message['fail'] = LANG_ERR_6;
}

$this->viewFile = INCLUDE_ROOT.'/template/message_body.tpl';

}

} else {

$this->viewFile = INCLUDE_ROOT.'/template/create_category.tpl';

}

}

}

?>
Now if you look at the Category class, the template file it sets is the "category_create.tpl" file, which I haven't created yet.  I'm expecting there to be an error associated with the template class and the file_get_contents function that calls the file, but like I said, I'm just getting a blank page.

I've never tried this approach before, so I have no idea what's causing this.  Any help would be greatly appreciated.

Hi Guys,   Greetings! Co - PHP freaks! I was hired by a company that requires me to create a purchase department program that will generate Quotations, P.O. , Receipt All of the database of this program will be stored to a server computer in a single office and all of the computer has a software that will access the data and should be able to generate a printable file like PDF or something. What is the best approach for this? any suggestions? I appreciate it in advance.     Cheers,

I'm trying to process MS words doc in PHP. I found some samples which use COM applications for this but not working properly (I get only exceptions and no result)
and I taught it's the version of word on my localhost or my OS so I tried them on with different windows OS and MS word. but same result, since it would be harder to make it work on remote server (the remote server needs to have MS word installed on) so I'm looking for different approach, what you think?? is there nay good one rather than COM applications? have you ever tried? is it possible to write code with other like ASP or java and combine it with PHP? every little piece of advice would be appropriated, thanks

hello dear community,

i am currently wroking on a approach to parse some sites that contain datas on Foundations in Switzerland
with some details like goals, contact-E-Mail and the like,,,

See http://www.foundationfinder.ch/  which has a dataset of 790 foundations. All the data are free to use - with no limitations copyrights on it.

I have tried it with PHP Simple HTML DOM Parser - but , i have seen that it is difficult to get all necessary data -that is needed to get it up and running.

Who is wanting to jump in and help in creating this scraper/parser.   I love to hear from you.

Please help me - to get up to speed with this approach?


regards
Dilbertone

All good with sending single dimensional form data to the server using application/x-www-form-urlencoded, and having PHP convert it into an array.  Also, good with sending simple arrays using [].  But then I find myself needing to send a deeper object to the server .  For example, I have a form with three text inputs simpleFormName 1, 2, and 3 plus some deeper object.

Array
(
    [simpleFormName1] => bla
    [simpleFormName2] => bla
    [simpleFormName3] => bla
    [deeperObject] => Array
        (
            [0] => Array
                (
                    [prop1] => bla
                    [prop2] => true
                    [data] => Array
                        (
                            [0] => Array
                                (
                                    [p1] => 321
                                    [p2] => 123
                                )

                            [1] => Array
                                (
                                    [p1] => 121
                                    [p2] => 423
                                )

                            [2] => Array
                                (
                                    [p1] => 221
                                    [p2] => 133
                                )

                        )

                )

            [1] => Array
                (
                    [prop1] => blabla
                    [prop2] => false
                    [data] => Array
                        (
                            [0] => Array
                                (
                                    [p1] => 222
                                    [p2] => 443
                                )

                            [1] => Array
                                (
                                    [p1] => 321
                                    [p2] => 213
                                )

                            [2] => Array
                                (
                                    [p1] => 111
                                    [p2] => 421
                                )

                        )

                )

        )

)

 

I see at least four options:

Come up with naming structure which "flattens" the data.  I have used this approach in the past, but it quickly becomes difficult to manage and I don't want to do so. Not use PHP's POST and and instead use Content-Type: application/json and file_get_contents(php://input) and json_decode the entire request server side. Use PHP's POST and urlencoding but make deeperObject a string using JSON.stringify and json_decode this one field server side. Urlencode the entire object.

simpleFormName1=bla&simpleFormName2=bla&simpleFormName3=bla&deeperObject%5B0%5D%5Bprop1%5D=bla&deeperObject%5B0%5D%5Bprop2%5D=true&deeperObject%5B0%5D%5Bdata%5D%5B0%5D%5Bp1%5D=321&deeperObject%5B0%5D%5Bdata%5D%5B0%5D%5Bp2%5D=123&deeperObject%5B0%5D%5Bdata%5D%5B1%5D%5Bp1%5D=121&deeperObject%5B0%5D%5Bdata%5D%5B1%5D%5Bp2%5D=423&deeperObject%5B0%5D%5Bdata%5D%5B2%5D%5Bp1%5D=221&deeperObject%5B0%5D%5Bdata%5D%5B2%5D%5Bp2%5D=133&deeperObject%5B1%5D%5Bprop1%5D=blabla&deeperObject%5B1%5D%5Bprop2%5D=false&deeperObject%5B1%5D%5Bdata%5D%5B0%5D%5Bp1%5D=222&deeperObject%5B1%5D%5Bdata%5D%5B0%5D%5Bp2%5D=443&deeperObject%5B1%5D%5Bdata%5D%5B1%5D%5Bp1%5D=321&deeperObject%5B1%5D%5Bdata%5D%5B1%5D%5Bp2%5D=213&deeperObject%5B1%5D%5Bdata%5D%5B2%5D%5Bp1%5D=111&deeperObject%5B1%5D%5Bdata%5D%5B2%5D%5Bp2%5D=421

Any recommendations how to best implement?  If you recommend using urlencoding for simple forms, but some other approach for more complex data, what criteria do you use to transition from one approach to another?

Thanks

I have good knowledge of HTML, Css, Php and mysql, i would want to know, the best approach to creating an online dating site. any help 

good evening dear Community, 

Well first of all: felize Navidad - I wanna wish you a Merry Christmas!!

Today i'm trying to debug a little DOMDocument object in PHP. Ideally it'd be nice if I could get DOMDocument to output in a array-like format, to store the data in a database!

My example: head over to the url -
see the example: the target http://dms-schule.bildung.hessen.de/suchen/suche_schul_db.html?show_school=8880   

I investigated the Sourcecode:

I want to filter out the data that that is in the following class <div class="floatbox">

See the sourcecode:


<span class="grey"> <span style="font-size:x-small;">&gt;</span></span>
<a class="navLink" href="http://dms-schule.bildung.hessen.de/suchen/index.html" title="Suchformulare zum hessischen schulischen Bildungssystem">suche</a>
              </div>
            </div>
          <!-- begin of text -->
           <h3>Siegfried-Pickert Schule</h3>
 <div class="floatbox">



See my approach: Here is the solution return the labels and values in a formatted array ready for input to mysql!

<?php

$dom = new DOMDocument();
@$dom->loadHTMLFile('http://dms-schule.bildung.hessen.de/suchen/suche_schul_db.html?show_school=8880');
$divElement = $dom->getElementById('floatbox');

$innerHTML= '';
$children = $divElement->childNodes;
foreach ($children as $child) {
$innerHTML = $child->ownerDocument->saveXML( $child );

$doc = new DOMDocument();
$doc->loadHTML($innerHTML);
//$divElementNew = $dom->getElementsByTagName('td');
$divElementNew = $dom->getElementsByTagname('td');

    /*** the array to return ***/
    $out = array();
    foreach ($divElementNew as $item)
    {
        /*** add node value to the out array ***/
        $out[] = $item->nodeValue;
    }

echo '<pre>';
print_r($out);
echo '</pre>';

} 



well Duhh: this outputs lot of garbage. The code spits out a lot of html anyway.
What can i do to get a more cleaned up code!?

What is wrong with the idea of using this attribute:

 $dom->getElementById('floatbox');

any idea!?

any and all help will greatly appreciated.

I am trying to wrap my head around the best approach to accomplish this.   I am trying to come up with a random schedule for a full 24 hour day with random time periods ranges including breaks. The only constants will be the minimum time and maximum time of the events and the minimum and maximum time of the breaks between each event.   for example There are three teams Team A Team B Team C   Each event will last either a minimum of 7 minutes to a maximum of 38 minutes The breaks will last a minimum of 30 seconds to a maximum of 5 minutes.   so the events need to be generated randomly with a break period following each event and the timelines are different for each team with the current event time left going to  a timer on the page   I think I have the part to generate the random blocks figured out by using 

<!DOCTYPE html>
<html>
<body>
<?php
function eventRange($min, $max, $blocks) {
    $events = range($min, $max);
    shuffle($events);    
    return array_slice($events, 0, $blocks);
    
}

function breakRange($min, $max, $blocks) {
    $breaks = range($min, $max, 0.1);
    shuffle($breaks);    
    return array_slice($breaks, 0, $blocks);
    
}
echo"<pre>";
print_r( eventRange(7,38,32) );
echo"</pre>";

echo"<pre>";
print_r( breakRange(.5,5,32) );
echo"</pre>";

?>
</body>
</html>

bur is there a way to make it fill a full 24 hour period and then a way to determine which block to display based on the current time when either team is viewing the page.   Sounds totally confusing to me as I try to explain it so I hope what Im asking makes sense. Thanks for any guidance..          

Hi,

Is this the correct way to go by setting cookies for my login 'remember' functionality?, I've posted the relevant login and logout code.

Login:

<?php
session_start();

//some code...

if (isset($_POST['remember'])) {

$expire = time() + 1728000; // Expire in 20 days

$site_domain = 'phpfreaks.com'; //example

$_SESSION['username'] = $_POST['username']; //don't worry this has been validated :D

$username = $_SESSION['username'];

//some sql query to fetch code..

$code = $row['code'];

setcookie('username', $username, $expire, NULL,  ".$site_domain", NULL, TRUE);

setcookie('code', $code, $expire, NULL, ".$site_domain", NULL, TRUE);

}
?>


Logout:

<?php
session_start();

if (isset($_COOKIE['username'])) {

$expire = time() - 1728000; // Expire in 20 days

$site_domain = 'phpfreaks.com'; //example

$username = $_SESSION['username'];

//some sql query to fetch code..

$code = $row['code'];

setcookie('username', $username, $expire, NULL, ".$site_domain", NULL, TRUE);

setcookie('code', $code, $expire, NULL, ".$site_domain", NULL, TRUE);

}

unset($_SESSION['username']);

$_SESSION = array();

session_destroy();
?>


Please tell me if it looks good to go and/or any improvements.

PS:

I want it accessible on all areas of the domain (including subdomains and paths etc.), and HTTP ONLY (so js can't access it) - I believe I've set the right parems?

hi i would like to know why this doesnt work .the problem is that it doesnt give me multiple  tr-s like td-s.it only works for one tr and multiple td-s. help apreciated

I have using gmdate() to get the GMT time but as it does not take in to account daylight saving the time is one hour behind.

Does anyone have a fix that can work out the correct time what ever time of year it is?

As I am currently having to change the code each time the time changes.

Hi,

Im pretty much self taught when it comes to php, never read any books just picked things up as i go, and im looking for some advice on how i build my pages as i believe im not approaching it correctly.

Basically i build an index.php, this contains my header, footer, and any menus i may have, then for my content pages, in this case products, contact, about us i use use an include so these content pages just have content.

Now by doing this my address bar looks like this index.php?location=contact.php

for the sake of google and search results and so on, am i limiting my ability to be found by not using a differant file for each page? should i include a header, footer, menu etc within my content pages rather than the other way around?

Thanks in advance for any advice.

Hi, im trying to create a link where it takes the row reference number and direct user to the revelant page, however i can get it work, this is my URL HREF

<td><?php echo $reference; ?><?php echo "a href='display.php?reference=".$row['reference']."'?>View Here</a>"</td>

Hello all,
I'm trying to write a joomla page that will import LinkShare banners into the banner component.  The problem I'm having is that LinkShare doesn't seem to always have the correct image size listed.  If I use their dimensions, the images come out skewed and bad looking.
So I'm trying to use getimagesize, to get the real dimensions, and it's still not working.

Please take a look, and let me know if you have any suggestions.
