[making a pagination from data array with ajax and jquery!]

I am using ajax to get an array of data.

 

I then output the contents of array to the screen.

 

Is there any pagination that will work with array, and without reloading the page.

 

Thank you!

[Is it possible to retrieve data from controller with ajax in php mvc?]

[is there any way to export data from php to javascript and using ajax to grab it]

I was thinking of json, but the server what i am trying to do it is running php 5.1.6, but json_encode needs 5.2.0.

 

i wonder if there is anything that i could do, to use one of the following: print_r(), var_dump(), var_export() or anything else, to dump the information on the screen, then grab with ajax and save it as a javascript array.

 

thx.

[Is it possible to retrieve data from controller with ajax in php mvc?]

my ajax function:

function getGroupDataWithAjax(){
$(document).ready(function() {
  		var data = $.ajax({
  		url: "groupData.php",
  		async: false
		}).responseText;
	return data;
});
}

 

function in my controller:

function getGroupData(){
	$groupData = $this->HomeModel->returnGroups();
	return	$groupData;
}

 

what i would like to do, is to call groupData.php with ajax, and store in a variable for later use.

[Having big issues with session variables!]

I figured out the issue somewhat.

 

I am using and mvc design. And when i research it, i found out that i either need to make a library to handle session variables or use cookies. Since i used the code for mvc of tutorial on build your own mvc that i found on some site, its pretty bugged. When i tried cookies, they seem to work, but i will test them out more concretely tomorrow.

[Having big issues with session variables!]

I have a header.php which is included to all php files.

 

Header.php has the following:

<?php 
session_start();
if(isset($_SESSION)|| $_SESSION != null){
if(isset($_SESSION['message'])){
	echo '<br />Login status: '. $_SESSION['message'] ;

}
}

?>

 

I have a login.php which has header.php included.

 

<?php
include header.php
...code

if($validate){$_SESSION['message']  = 'Validated';}
else{$_SESSION['message']  = 'Unautorized';}
?>

 

when i refresh the page after submit , and check for $_SESSION['message'] it is always empty.

same thing is i created another php page, included header.php, and when i redirect to it after login.php the session variable is still empty?

 

Cant figure out why.

[Question regrading mvc, model and controller!]

thank you for all of the info!

[Question regrading mvc, model and controller!]

Yes, Home is object of class home. The MVC that i am using, there isnt much documentation explaining every little detail.

 

I searched though codes from various tutorials from the same author of MVC until l i came upon that line. And when i modified to work with my model and function it work.

 

And it also did not required for me to do any includes.

 

The main issues as i have stated above, i haven't touched php for a couple of years. Thats why it is a little slow for me at this time.

[Question regrading mvc, model and controller!]

As far as i understand, $this refers to current class.

 

Most likely there is an instance of Home class too somewhere.

 

Since there is an instance of home class, calling its function works no problem.

 

This is as far as i can explain it for now.

[Question regrading mvc, model and controller!]

Edit:

Ok, I have figured out what i needed to have:

$this->Home->printText('123');

Home is the name of the model, while printText the name of the function.

 

[Question regrading mvc, model and controller!]

Here is what i did:

 

<?php
class HomeController extends Controller {

function __construct() { 
	$model = new Home();
} 

function index($id = null,$name = null) {

	$this->set('title',$name.' - First Test page');
	//$this->set('todo',$this->Item->select($id));
	$model->printText('123');
}
}

 

Here is what it tells me only when i add __construct:

Fatal error: Call to a member function set() on a non-object in /usr/local/www/vhosts/htdocs/library/controller.class.php on line 21

 

controller.class.php

<?php
class Controller {

protected $_model;
protected $_controller;
protected $_action;
protected $_template;

function __construct($model, $controller, $action) {

	$this->_controller = $controller;
	$this->_action = $action;
	$this->_model = $model;

	$this->$model =& new $model;
	$this->_template =& new Template($controller,$action);

}

function set($name,$value) {
#this line#		$this->_template->set($name,$value);
}

function __destruct() {
		$this->_template->render();
}

}

[Question regrading mvc, model and controller!]

here is what i did:

 

<?php
include('home.php');
class HomeController extends Controller {
$model = new Home();

function index($id = null,$name = null) {

	$this->set('title',$name.' - First Test page');
	$model->printText('123');
}
}

 

I get the following:

Parse error: syntax error, unexpected T_VARIABLE, expecting T_FUNCTION in /usr/local/www/vhosts/htdocs/application/controllers/homecontroller.php on line 4

[Question regrading mvc, model and controller!]

I have done mvc few years back, but forgot most of it.

when i need to access functions of model from controller class. How would i do that?

 

I have home controller and home model.

[running a javascript function inside jquery]

I cant say if what was the case or not. but it seemed the colorbox was not compatible with jquery 1.4.1 and I have applied 1.3.2 for which it automatically grabs the height, and I dont need to specify it. But thx for the suggestion. I will test the code separately.

[running a javascript function inside jquery]

Hi,

 

I have the following line:

$.fn.colorbox({inline:'true', href:'#content-area',width:'700px', height:getHeight() });

 

From the following code:

var boxHeight = document.getElementById('content-area').clientHeight;
function getHeight(){
    boxHeight += 90;
return  boxHeight = boxHeight + "px";    
}
if(boxHeight > 200){
$(document).ready(function(){
$.fn.colorbox({inline:'true', href:'#content-area',width:'700px', height: getHeight() });
});}

 

jquery fn.colorbox just would not run if I put getHeight() in it. Any ways to go around it or fix it?

[Getting html loaded in div container via link! code not working.]

nvm I got it working

[Getting html loaded in div container via link! code not working.]

Hi,

 

I am trying to load html page into div via link.

here is my code.

 

<a href="?p=index">Main</a>
<a href="?p=history">history</a>

<div id='content'>
<?php
if(isset($_GET['p'])) 
{
$p = $_GET['p'];

include($p.'.htm');

} else {
include('index.htm');
}
?>
</div>

 

But the thing nothing happens, I have tried to echo, and that doesn't even get printed out.

[cant get margin-left to work.]

There is probably a CSS selector with a higher precedence than the selector you are trying to use.

 

Use Firefox with the firebug plugin, and inspect that element (the left sidebar) to find out which selector is taking higher precedence.

 

Actually, there is one other possibility with Drupal - you may have your CSS set to cache. Go to admin->settings->performance (Drupal 6), and see if it is. You can clear your cache there, and any changes you have made may start to work, if there isn't a selector with higher precedence.

 

I have tried clearing css cashe. No change.

 

Thanks, I completely forgot about firebug. It was layout-liquid.css that was taking precedence.

[cant get margin-left to work.]

Here is the div element, its an id.

 

<div id="sidebar-left"><div id="sidebar-left-inner" class="region region-left">
          <?php print $left; ?>
        </div></div> <!-- /#sidebar-left-inner, /#sidebar-left -->

 

Although I have no idea what this means 'class="region region-left"'. I have tried to remove it, nothing happends.

[cant get margin-left to work.]

I am customizing drupal zen theme.

 

I am trying to set left margin of a div element using css.

#sidebar-left
  {
  margin-left:20px;
}

 

When I test it out nothing happens.

 

Any help would be appreciated.

 

[mssql query analyser returns results, while php returns [rownum] => -1 ?]

It might not like that it is two queries.  (That could potentially return 2 row resources, and I bet MDB2 wasn't designed for that.

 

I would suggest just breaking it into 2 query() calls.

 

I think I have already tried that. But I will try again.

 

Thank you!

 

I have tryed to run it into 2 query calls, but I dont think I was doing it correctly, would you be able to show me an example.

 

Than you!
