<?php
$id = (isset($_GET['id'])); set the value
switch($id) {

break;
case 'aventura':include('/aventura/index.php');//second page
break;
}
?>
It takes me to /action/index.php when i access adventure Why?
Please I need a bit of help
Because you're switching on true/false here, as the result of isset - which is always boolean value - is assigned to $id directly. This line should be rewritten as...
$id = isset($_GET['id']) ? $_GET['id'] : '';
... where '' can be actually replaced with that default value.
In fact, you can redirect user at the very moment when you find that $_GET['id'] is empty, then analyze it's different values with switch. Like this:
if (! isset($_GET['id'])) { ... redirection ... }
switch ($_GET['id']) {
case 'first': ...; break;
case 'second': ...; break;
default: ...;
}

I want to send the value of textbox to the Action Method for searching the technology for that i want to get the value of textbox in Action.
I have the following code :-
#Html.TextBox("technologyNameBox", "", new { id = "technologyName", #class = "form-control", #placeholder = "Search For Technology" })
<span class="input-group-btn" style="text-align:left">
<a class="btn btn-default" id="searchTechnology"
href="#Url.Action("SearchTechnology", "Technology",
new {technologyName="technologyName",projectId=ProjectId })">
<span class="glyphicon glyphicon-search "></span>
</a>
</span>
Question :- How to get the value of textbox "technologyNameBox" in Action ?
Please help me out. Thanks in Advance!
You'd have to append the value to the URL via JavaScript before directing the user. Using jQuery (since that generally comes packaged with ASP.NET), it might look something like this (with a good bit of manual conditional checks for blank values or query string parameters):
$('#searchTechnology').click(function (e) {
e.preventDefault();
var url = '#Url.Action("SearchTechnology", "Technology", new { projectId=ProjectId })';
var technologyName = $('#technologyName').val();
if (technologyName.length < 1) {
// no value was entered, don't modify the url
window.location.href = url;
} else {
// a value was entered, add it to the url
if (url.indexOf('?') >= 0) {
// this is not the first query string parameter
window.location.href = url + '&technologyName=' + technologyName;
} else {
// this is the first query string parameter
window.location.href = url + '?technologyName=' + technologyName;
}
}
return false;
});
The idea is that when the user clicks that link, you would fetch the value entered in the input and append it to the URL as a query string parameter. Then redirect the user to the new modified URL.
I am developing an application using CakePHP 2.6 and having issues with passing a string containing url characters as a parameter through to a controller method.
In my view I have a chunk of code which echoes out a series of table rows containing data and passes through the page id, unit id and the id of the link which can sometimes contain a url.
<?php foreach($linklist as $l) { ?>
<tr id="Link_<?php echo $l['ID']; ?>">
<td><?php echo $l['Title']; ?></td>
<td class="buttontd"><?php echo $this->Form->postlink('Delete', array('action' => 'deletelink', $this->request->params['pass'][0], $results[0]['PageUnitTypeID'], $l['ID']), array('class' => 'button delete')); ?></td>
</tr>
<?php } ?>
When the postlink button passes the information over to the 'deletelink' action in the controller the url looks like this:
http://mydomainname.com/webpages/deletelink/239/7/urlhttp%3A%2F%2Fwww.google.co.uk%2F
Which shows that the url has been passed as the string but then in the action when I try to just var_dump() the third parameter it returns a string of www.google.co.uk and nothing more which is preventing me from doing a substr() call on the parameter to check if the first 3 characters are equal to url or not.
I have tried to wrap the parameter in the postlink call inside serialize() and urlencode() but neither has had the desired effect of returning the full string as
urlhttp%3A%2F%2Fwww.google.co.uk%2F
Does anyone know of a successful way to pass through a parameter like this without losing important characters?
Update 1: Deletelink action
public function deletelink($pid = null, $uid = null, $lid = null) {
$this->autoRender = false;
if (!is_null($pid) && is_numeric($pid) && !is_null($uid) && is_numeric($uid)) {
if (!is_null($lid)) {
if (substr($lid, 0, 3) == 'url') {
echo substr($lid, 0, 3);
} else {
echo substr($lid, 0, 3);
}
} else {
$this->Session->setFlash('It is unknown which link you wish to delete from the webpage', 'flash_message_bar', array('class' => 'error'));
return $this->redirect(array('action' => 'edit', $pid));
}
} else {
$this->Session->setFlash('It is unknown which on which webpage you wish to delete a link', 'flash_message_bar', array('class' => 'error'));
return $this->redirect(array('action' => 'index'));
}
}
CakePHP (or mod_rewrite I would say) is getting confused with the way your URL is formed.
Your safest option is to base64_encode the url parameter in the view, which will result in call similar to:
http://mydomainname.com/webpages/deletelink/239/7/dXJsaHR0cDovL3d3dy5nb29nbGUuY28udWsv
and base64_decode it later in the action, which will transform
dXJsaHR0cDovL3d3dy5nb29nbGUuY28udWsv
into
urlhttp://www.google.co.uk/
How to disable particular layout(example:menus.phtml) for particular pages in controller in ZF2?? In the below example menus.phtml should be disable for specific pages. Remaining pages must contain menus.phtml like header and footer.
<div>
header.phtml
</div>
<div>
menus.phtml
</div>
<div>
<?php echo $this->content; ?>
</div>
<div>
footer.phtml
</div>
There are various aproaches to this. Also modules.zendframework has quite a few modules here that may help you out.
If you are still keen on writing that yourself you could add variables to your layout within your controllers like so:
<?php
//YourController.php
public function someAction()
{
...
$this->layout()->footer = 'default';
...
}
//layout.phtml
<?php if ($this->footer === 'default') : ?>
//show the footer
<?php endif; ?>
Doing this is pretty inefficient though. Just imagine you'd need to do this to every action in all the controllers... I sure would not like to do that.
Now zf2 has a service and event layer that could help us out quite a bit here. This is a pretty nice read and introduction to it. You'd just write a service and trigger a event on your controllers/routes/whatever. Now you would also probably like to configure what is shown and what is hidden right? Thats pretty easy, too. Just write yourself a config file and merge it with the global.config like so:
<?php
//CustomModule/module.php
public function getConfig() {
$config = array();
$configFiles = array(
include __DIR__ . '/config/module.config.php',
include __DIR__ . '/config/module.customconfig.php',
);
foreach ($configFiles as $file) {
$config = \Zend\Stdlib\ArrayUtils::merge($config, $file);
}
return $config;
}

First, get the controller or action name:
$controllerName =$this->params('controller');
$actionName = $this->params('action');
then in your layout/view script add a simple logic.
<?php if ($actionName != 'action that you want to disable the layout/menu'): ?>
echo $this->render('menus.phtml');
<?php endif; ?>
In a ZF2 project I am developing, I would like to create a shell around the echo $this->content; statement in layout.phtml that would allow conditional formatting of the main content area. Specifically, I want to put the content into a column that is 75% wide and include some “ornamental” elements in a column that is 25% wide for most of the pages. However, I want to change to a single column for pages that need more space. My project is a CMS in which each page has an attribute that can tell either the view or the controller whether the page should be normal or wide. I have considered a number of methods for achieving what I’m after.
My “conditional formatting in the layout view” might look like this:
// module/Application/view/layout/layout.phtml:
//...
if ($templateNormal) {
echo "<div class='col-md-9'>";
} else {
echo "<div class='col-md-12'>";
}
echo $this->content;
if ($templateNormal) {
echo "</div>";
echo "<div class='col-md-3'>";
//... ornamentation
echo "</div>";
} else {
echo "</div>";
}
//...
While the above-method could work, for pure MVC I don’t think there is supposed to be any decision-making going on in the layout view.
My “conditional formatting in partial views” could look like this:
// module/Application/view/layout/layout.phtml:
//...
echo $this->partial('partial/open-shell.phtml');
echo $this->content;
echo $this->partial('partial/close-shell.phtml');
//...
// module/Application/view/partial/open-shell.phtml:
if ($templateNormal) {
echo "<div class='col-md-9'>";
} else {
echo "<div class='col-md-12'>";
}
// module/Application/view/partial/close-shell.phtml:
if ($templateNormal) {
echo "</div>";
echo "<div class='col-md-3'>";
//... ornamentation
echo "</div>";
} else {
echo "</div>";
}
Here the decision-making is taken out of the layout view, but it is simply put into other views so it's still in the view package and still not pure MVC.
In my “conditional formatting in the controller” solution, a pair of html script strings are developed in a controller function, and then passed on to the view. It might look like this:
// module/Application/view/layout/layout.phtml:
//...
echo $this->open-shell-script';
echo $this->content;
echo $this->close-shell-script';
//...
// some controller function:
//...
if ($templateNormal) {
$open-shell-script = "<div class='col-md-9'>";
$close-shell-script = "</div>";
$close-shell-script = "<div class='col-md-3'>";
$close-shell-script .= //... ornamentation
$close-shell-script .= "</div>";
} else {
$open-shell-script = "<div class='col-md-12'>";
$close-shell-script = "</div>";
}
//...
In this method, the decision-making is done in the controller where I assume it should be, but it seems odd to be writing html there.
Any comments or suggestions?
create two layout and in init() method of Module.php decide which layout should use .
public function init(ModuleManager $moduleManager) {
$sharedEvents = $moduleManager->getEventManager()->getSharedManager();
$sharedEvents->attach(__NAMESPACE__, 'dispatch', function($e) {
// This event will only be fired when an ActionController under the MyModule namespace is dispatched.
$controller = $e->getTarget();
$controller->layout(" your chose layout ");
}
}
There are many ways to accomplish this. This is one method and the logic lives in the controller:
controller
public function yourSampleAction()
{
// assign variables as usual to this view model
$viewModel = new ViewModel(array(
//vars
);
// this will be the "wrapper" and can be single, double column or anything else.
$wrapperViewModel = new ViewModel();
$wrapperViewModel->addChild($viewModel, 'innerContent');
// use this line when you want one column
$wrapperViewModel->setTemplate('path/to/your/single-column-wrapper.phtml');
// when this line you want two columns
$wrapperViewModel->setTemplate('path/to/your/two-column-wrapper.phtml');
return $wrapperViewModel;
}
two-column-wrapper.phtml
<div class='col-md-9'>
<?php echo $innerConntent; ?>
</div>
<div class='col-md-3'>
<!--- something else in here? -->
</div>
single-column-wrapper.phtml
<div class='col-md-12'>
<?php echo $innerConntent; ?>
</div>
Instead of setting different templates, you can adjust the Bootstrap Twitter classes by making the necessary classes dependent on a layout variable. You can use the logic in your controllers action to pass variables directly to the layout (not the view) like so:
$this->layout()->setVariables
(
array
(
'layoutVar1' => 75,
'someColClass' => ($someSwitch ? 'col-md-9':'col-md-12' ),
'layoutVar1' => 75,
)
);
and then just access these variables in the Layout as you would variables sent to the View. You don't have to even prepend them with "layout", they won't clash.
I was researching about how to check if the cookies are enabled in a browser and i found a lot of answer, i even tested a few ones, but after that a friend of mine suggest me to use Modernizr for that.
I started to search about that and i found a lot of stuff related with CSS3 and HTML5, but i don't want that, i just wanna know if is it possible to check that cookies are enabled or not with Modernizr?
check this url, hope it's helpful :
https://github.com/Modernizr/Modernizr/commit/33f00fbbeb12e92bf24711ea386e722cce6f60cc
Below code is copied from http://sveinbjorn.org/cookiecheck.
function are_cookies_enabled()
{
var cookieEnabled = (navigator.cookieEnabled) ? true : false;
if (typeof navigator.cookieEnabled == "undefined" && !cookieEnabled)
{
document.cookie="testcookie";
cookieEnabled = (document.cookie.indexOf("testcookie") != -1) ? true : false;
}
return (cookieEnabled);
}
A direct answer to the question is 'Yes!' and it is built in
Example code:
if (Modernizr.cookies == false) {
alert('Please enable cookies');
}
else {
// do something with cookies
}
You can also use the css class .cookies or .no-cookies to show/hide a panel telling the user they need cookies enabled.
.cookies #noCookies
{
display: none;
}
<div id='#noCookies'>
This site requires cookies! Please turn them on already!
</div>
(This .cookies class is added to <body> tag by Modernizr).
Note: If you are creating a custom build of Modernizr the cookies option is currently 'hidden' under the 'Non-core detects' section.
Another way with PHP
HTML/PHP:
<?php
session_start();
$_SESSION['cook'] = 1;
echo "<img src=\"cookcheck.php\">";
?>
PHP - cookcheck.php:
<?php
session_start();
if ($_SESSION['cook'] !== 1)
{ $image="/nocookmsg.png"; } # Cookies NOT Enabled
else { $image="/blank.png"; } # Cookies Enabled
$img=imageCreateFromPNG($image); # Create Image
header("Content-type: image/png"); # Send Header
imagePNG($image); # Send Image
?>
