Content of form.php joomla part 4

2010-07-04T13:39:00.011+05:30

We already discussed the behaviours of controllers in the last tutorial. Now it is time to learn the syntax of ‘form.php’ and ‘view.html.php’.

form.php use for both data insert and edit.

Here is the sample code of form.php

com_lanka1->views->lanka1->tmpl->form.php


<?php defined('_JEXEC') or die('Restricted access'); ?>
<?php
/**
* Lanka  Map default controller
*

?>

<form action="index.php" method="post" name="adminForm" id="adminForm">
<div class="col100">
<fieldset class="adminform">
<legend><?php echo JText::_( 'Details' ); ?></legend>

<table class="admintable">

<tr>
<td width="100" align="right" class="key">
<label for="greeting">
<?php echo JText::_( 'Your name'); ?>:
</label>
</td>
<td>
<input class="text_area" type="text" name="greeting" id="greeting" size="32" maxlength="250" value="<?php echo $this->lanka1->your_name;?>" />
</td>
</tr>
<tr>

</label>
</td>

Not only form.php but also view.html.php is essential to success this stage

2010-07-02T21:39:00.011+05:30

Lesson part 2, used to Describe only displaying information from table. But do you know how to add recodes to table? Answer is Nop.

Ok let's see how to insert data to table. Can u see there is button called "New"? Admin panel will popup html form once you click "New" button. What are the place and which are the file we used in here?

1.First Change

open - com_lanka1->views->lanka1s->tmpl->default.php

can u see there is code like,



<input type="hidden" name="controller" value="lanka1"/>

In above code, ple change "lanka" instead of" lanka1" where value of controller

2.Add new controller
add new folder "controllers" to your component folder[com_lanka1]

make new file "lanka.php"

com_lanka1->controllers->lanka.php



<?php
/**
* Lanka1   default controller
*
* @package    Joomla.component

function __construct()
{
parent::__construct();

// Register Extra tasks
$this->registerTask( 'add'  ,  'edit' );
}

/**
* display the edit form
* @return void
*/
function edit()
{

JRequest::setVar( 'view', 'Lanka1' );
JRequest::setVar( 'layout', 'form'  );
JRequest::setVar('hidemainmenu', 1);

parent::display();
}

/**
* save a record (and redirect to main page)
* @return void
*/
function save()
{
$model = $this->getModel('Lanka1');

if ($model->store($post)) {
$msg = JText::_( 'Lanka1 map Saved!' );
} else {
$msg = JText::_( 'Error Saving Lanka1 ' );
}

// Check the table in so it can be edited.... we are done with it anyway
$link = 'index.php?option=com_Lanka1';
$this->setRedirect($link, $msg);
}

/**
* remove record(s)
* @return void
*/
function remove()
{
$model = $this->getModel('Lanka1');
if(!$model->delete()) {
$msg = JText::_( 'Error: One or More Lanka1 map Could not be Deleted' );
} else {
$msg = JText::_( ' Lanka1 map(s) Deleted' );
}

$this->setRedirect( 'index.php?option=com_Lanka1', $msg );
}

/**
* cancel editing a record
* @return void
*/
function cancel()
{
$msg = JText::_( 'Operation Cancelled' );
$this->setRedirect( 'index.php?option=com_Lanka1', $msg );
}
}

Can u see wt are the code of function edit()

JRequest::setVar( 'view', 'Lanka1' ); call Lanka1 folder under view folder
JRequest::setVar( 'layout', 'form' ); call form.php
JRequest::setVar('hidemainmenu', 1); hide main manu

Advance joomla component with table connection part 1

2010-06-30T19:36:00.024+05:30

The following image shows the appearance of the admin panel of our component. Ok, let's try to load the table data [jos_contactUs] to here. For that we need to modify default.php form with the following code: -

com_lanka1->views->lanka1s->tmpl->default.php


<?php defined('_JEXEC') or die('Restricted access'); ?>
<?php
/**
* Google  Map default controller
*
* @package    Joomla.component
* @subpackage Components
* @link http://inetlanka.com
* @license  GNU/GPL
* @auth inetlanka web team - [ info@inetlanka.com / wapnishantha@gmail.com ]
*/
?>
<form action="index.php" method="post" name="adminForm">
<div id="editcell">
<table class="adminlist">
<thead>
<tr>
<th width="5">
<?php echo JText::_( 'ID' ); ?>
</th>
<th width="20">
<input type="checkbox" name="toggle" value="" onclick="checkAll(<?php echo count( $this->items ); ?>);" />
</th>
<th>
<?php echo JText::_( 'Telephone List' ); ?>
</th>
</tr>
</thead>
<?php
$k = 0;
for ($i=0, $n=count( $this->items ); $i < $n; $i++) {
$row = &$this->items[$i];
$checked  = JHTML::_('grid.id',   $i, $row->id );
$link   = JRoute::_( 'index.php?option=com_lanka1&controller=lanka1&task=edit&cid[]='. $row->id );
?>
<tr class="<?php echo "row$k"; ?>">
<td>
<?php echo $row->id; ?>
</td>
<td>
<?php echo $checked; ?>
</td>
<td>
<a href="<?php echo $link; ?>"><?php echo $row->your_name; ?></a>
</td>
</tr>
<?php
$k = 1 - $k;
}
?>
</table>
</div>

<input type="hidden" name="option" value="com_lanka1" />
<input type="hidden" name="task" value="" />
<input type="hidden" name="boxchecked" value="0" />
<input type="hidden" name="controller" value="lanka1" />
</form>

The last part of above code is very important, from the

to the

</form>

Note only default.php but also view.html.php is essential to success this stage

com_lanka1->views->lanka1s->view.html.php


<?php
/**
* Lanka1   default controller
*
* @package    Joomla.component
* @subpackage Components
* @link http://inetlanka.com

jimport( 'joomla.application.component.view' );

* @package    Joomla.component
* @subpackage Components
*/
class Lanka1sViewLanka1s extends JView
{
/**
* lanka1 view display method

**/
function display($tpl = null)
{
JToolBarHelper::title(   JText::_( 'Lanka1' ), 'generic.png' );
JToolBarHelper::deleteList();
JToolBarHelper::editListX();
JToolBarHelper::addNewX();

// Get data from the model
$items  = & $this->get( 'Data');

$this->assignRef('items',  $items);

parent::display($tpl);
}
}

This is first time we've used a module . On an MVC system, module is used to make a relationship between a table and a component.

In our example, we use two modules, lanka1.php and lanka1s.php as follows

com_lanka1->models->lanka1.php

com_lanka1->models->lanka1s.php

500 - An error has occurred - joomla

2010-05-22T07:10:00.000+05:30

Do u remember last time error? if not ple go here

"View not found [name, type, prefix]: lanka1s,html,lanka1sView" wt is this? this say, there is not 'view' page on this component. So today we can lean about 'how to make a view pages'

MVC or module view component, Now we are in view stage, For this we need new folder to store template files or view pages.

Ple make a new folder call "views" under that", again make a new folder call "lanka1s" and "view.html.php" file on there

see our folder structure

administrator->components->com_lanka1->views->lanka1s->view.html.php

see the content of "view.html.php"


<?php

/**
* Lanka1   default controller
*
* @package    Joomla.component

JToolBarHelper::deleteList();
JToolBarHelper::editListX();
JToolBarHelper::addNewX();




parent::display($tpl);
}
}

ooooop's he he ................ can u see there is another error

wt are the new things of this code

1.JToolBarHelper::title( JText::_( 'Lanka1' ), 'generic.png' );

this is use to set the TITLE of the page and can use existing image to take a handy look :D

2.JToolBarHelper::deleteList();

On this stage we do not need this but in future we need to delete items

3.JToolBarHelper::editListX();

On this stage we do not need this but in future we need to edit items

4. JToolBarHelper::addNewX()

On this stage we do not need this but in future we need to add items

failed to open stream - joomla

2010-04-28T08:20:00.000+05:30

Following error occur on last time article. Now we try to solve this issue ...............
"
Warning: require_once(C:\AppServ\www\Joomla\administrator\components\com_lanka1\controller.php) [function.require-once]: failed to open stream: No such file or directory in C:\AppServ\www\Joomla\administrator\components\com_lanka1\lanka1.php on line 17

Fatal error: require_once() [function.require]: Failed opening required 'C:\AppServ\www\Joomla\administrator\components\com_lanka1\controller.php' (include_path='.;C:\php5\pear') in C:\AppServ\www\Joomla\administrator\components\com_lanka1\lanka1.php on line 17
"

Wt is this error? Yes this is arising due to MVC. Base on MVC structure, our component automatically find "controller.php" file. But at the moment it is not in our com_lanka1 folder.

we can use any name for this. But standard naming is important. see the code of "lanka1.php" can u see

"require_once( JPATH_COMPONENT.DS.'controller.php' );"

code on their? Mmm ... this is the reason arrising above file not found issue.

Following code show the simple syntax of controller.php file


<?php
/**
* Lanka1  default controller
*
* @package    Joomla.component
* @subpackage Components
* @link http://inetlanka.com
* @license  GNU/GPL
* @auth inetlanka web team - [ info@inetlanka.com / wapnishantha@gmail.com ]
*/

// No direct access
defined( '_JEXEC' ) or die( 'Restricted access' );

jimport('joomla.application.component.controller');

/**
* Lanka1  Component Controller
*
* @package    Joomla.component
* @subpackage Components
*/
class Lanka1sController extends JController
{
/**
* Method to display the view
*
* @access public
*/
function display()
{
parent::display();
}
}

Can u guess the essential part of this code? Mmm ...........

yes it is "class Lanka1sController extends JController". Look wt is the text it use. "Lanka1sController" In this word, [ Did u remeber?our component name is com_lanka1 ]. Here we take it as lanka1s. must remember this "S" is very importent. And also our class extend to core joomla class through the "JController"

ok when after adding "controller.php" to our testing component [administrator ->components->com_lanka1->controller.php]. again visit following link, from joomla admin [ http://YOUR JOOMLA PATH/administrator/index.php?option=com_lanka1 ]

Is this the error? yes this is the error we face on this stage.
