With Zend Framework 1.10 I'm having a list with articles and an search field.
When typing something in the searchfield and hit the search button it generates me the following url:
https://example.org/products?category=12&no=
On the result of the searchpage you'll find the products matching to the search field.
If there are more than 10 products with the search attribute, there is a next button. For this next button im using the following code to generate the url, which will sadly not extend the already passed arguments (category and no).
<a href="<?php echo $this->url(array('page' => $this->next)); ?>">
<?php echo $this->translate('NextPage'); ?> >
It will redirect me on https://example.org/products
How to add the already passed GET argument from the form?
You can store the GET parameters from the search in the session so when you are requesting with the next url, you can retrieve the parameters previously entered in the search form.

Today I found a totally weird behaviour and I would like to stop it.
I use CakePhp 2.9 and have a search form, with which I want to search orders. My primary key in the model is the session_id due to relations to other models.
class Order extends AppModel
{
public $primaryKey = 'session_id';
I open my search form with
<?php echo $this->Form->create(
'Order',
array(
'url' => array('controller' => 'orders', 'action' => 'search')
)
); ?>
Which results in the following HTML:
<form id="OrderSearchForm" action="/orders/search" method="post" accept-charset="utf-8">
In the controller I do different things depending on the request being of the type post or not.
For debugging the weird behaviour I added the following debug lines in the controller:
if ($this->request->is('post')) {
debug('post');
} else if ($this->request->is('get')) {
debug('get');
} else {
debug($_REQUEST);
debug($_GET);
debug($_POST);
}
So as long as i search for other values than the session_id of my Order or combine the session_id with other search values everything is fine.
But as soon as I search ONLY for the session_id the generated HTML for the search form is changed to
<form id="OrderSearchForm" action="/orders/search/mysearchvaluesessionidstring" method="post" accept-charset="utf-8">
And when I then submit my form it is suddenly no longer considered as "post". The debug output for $_GET is still empty and the one for $_POST still filled, but the condition if ($this->request->is('post')) is not triggered anymore.
How can I change this behaviour?
It is possible that cake is changing the request type to PUT when the request data only contains the session id. You can get around this by checking if ($this->request->is(array('post', 'put'))) instead of just checking for POST requests.

I am looping some specific products on the home page but unable to generate the ADD TO CART URL in magento 2
How to generate ADD TO CART URL when displaying products in loop.
I know it's been a year since this has been touched on, but as I've just done what has been requested, I thought that I may post my solution to help others.
The other answers will work, but only for simple products, where no further input is required (e.g. selecting options). When using getAddToCartUrl(), Magento first checks if the products requires any options to be selected; if it does, then it will simply supply the URL to the product page instead.
To skip all of these checks and directly obtain the add to cart URL, then make use of the Magento\Checkout\Helper\Cart helper instead. If you are within a .phtml file, then this can be utilised simply by calling $this->helper:
$cartHelper = $this->helper('Magento\Checkout\Helper\Cart');
From there, you can generate the add to cart URL via getAddUrl(), ensuring you pass the product object as the parameter:
echo $cartHelper->getAddUrl($product)
For it to fully work, you must have a hidden field for the form key as described in the other answers, and if the product in question has compulsory options to choose from (e.g. a configurable product), then make sure you include those fields as well, otherwise you will get redirected to the product page itself, with a message informing the user that options are required.
The excellent solution is to use
$cartHelper = $this->helper('Magento\Checkout\Helper\Cart');
and after that
echo $cartHelper->getAddUrl($product);
this give add to cart URL every time
(for a simple product, for a simple product with custom options etc)
use following to generate add to cart URL in magento2:
$objectManager = \Magento\Framework\App\ObjectManager::getInstance();
$listBlock = $objectManager->get('\Magento\Catalog\Block\Product\ListProduct');
$addToCartUrl = $listBlock->getAddToCartUrl($product);
Add your button code into form with form key.. It will work
$objectManager = \Magento\Framework\App\ObjectManager::getInstance();
$listBlock = $objectManager->get('\Magento\Catalog\Block\Product\ListProduct');
$addToCartUrl = $listBlock->getAddToCartUrl($product);
<form data-role="tocart-form" action="<?php echo $addToCartUrl; ?>" method="post">
<?php echo $block->getBlockHtml('formkey')?>
<button type="submit"
title="Add to Cart"
class="action tocart primary">
<span>Add to Cart</span>
</button>
</form>
You can generate "add to cart" url by following code:
$objectManager = \Magento\Framework\App\ObjectManager::getInstance();
$listBlock = $objectManager->get('\Magento\Catalog\Block\Product\ListProduct');
$addToCartUrl = $listBlock->getAddToCartUrl($_product);
I have a simple search form I want to reuse across multiple pages in my codeigniter application. For example, right now I have a search form in the sidebar and I'm planning on displaying that sidebar on the index, about, and other pages.
I want to have the form validation display errors on the same page the users submits the form from.
For example:
User is on About page.
User submits form with invalid data
User sees error in the sidebar on the About page
and
User is on Index page.
User submits form with invalid data
User sees error in the sidebar on the Index page
But I'd like to reuse that form validation logic. I just want it to display the error on whichever page the user posted from.
Any ideas how to do that? Sorry for the noob question, I'm pretty new to CI.
Here you have to think globally.
Step.1 : Make one view file : display.php
which contains :
<div id = "main">
<div id = "header">
[load header file here]
</div>
<?php
if(validation_errors() != '') {
?>
<div id = "error">
<?=validation_errors()?>
</div>
<?php
}
?>
<div id = "content">
<?=$page?>
</div>
<div id = "footer">
[load footer file here]
</div>
</div>
Step.2 : About us Page.(controlller)
.... Your data ....
at end of controller function
$data['page'] = 'aboutus';
$this->load->view('display',$data);
With regards to your comment on the above question you could use Flash data
With the assumption that you have the session library loaded, here is a helper function.
function last_page($page = null){
$ci = get_instance();
if($page === null)
return $ci->session->flashdata('last_page');
$ci->session->set_flashdata('last_page', $page);
}
then you can call last_page('about'); at the top of the about page, and then when you want to find out what the last page you were on was you can just call last_page(); with no params.
In the User Guide, there's different ways to configure sets/groups of rules. Then you can simply have something like:
if ($this->form_validation->run('signup') == FALSE)
{
$this->load->view('myform');
}
else
{
$this->load->view('formsuccess');
}
Which will run your "signup" group of validations. To me, this is the cleanest way to achieve reusable validation rules.
This is a perfectly valid question.
I'm not a PHP expert, nor a CI expert, but the fact is sometimes you want to post to a controller that didn't create the view from which you're posting. Which means posting back to itself is not going to work.
I came across this post on the Ellislab forum:
http://ellislab.com/forums/viewthread/217176/
On this page, There are 2 methods of going about it. Both of which use flashdata and both of which are totally valid, IMHO.
The first: create a helper function
http://ellislab.com/forums/viewreply/1003010/
The second: extend the CI_Form_Validation Class.
http://ellislab.com/forums/viewreply/1047536/
The second is the way I went as it seems cleanest although some may argue whether the form validation class should know anything about flash data.
I am using an application (a blog) written using the CodeIgniter framework and would like to search my blog from my browsers location bar by adding a string to the end of my blogs url like this:
http://mysite.com/blog/index.php/search...
As you can see in the example above I am not really sure how to format the rest of the url after the search part so I am hoping someone here might be able to point me in the right direction.
This is what the form looks like for the search box if that helps at all.
form class="searchform" action="http://mysite.com/blog/index.php/search" method="post">
<input id="searchtext" class="search_input" type="text" value="" name="searchtext">
<input type="submit" value="Search" name="Search">
</form>
Thx,
Mark
Since your form is posting to http://mysite.com/blog/index.php/search, I'm assuming this 'search' controller's default function is the one your are attempting to submit your data to. I think that the easiest way to do this would be to just grab the post data inside of the controller method you're posting to. Example:
function search()
{
$search_params = $this->input->post('search_text');
}
Then you would have whatever the user input stored as $search_params, and you can take actions from there. Am I misunderstanding what you're asking?
It seems like you're kind of discussing two different approaches. If you wanted to make a request to
mysite.com/blog/index.php/search&q=what_I_am_looking_for
This is going to call the search controllers default method (which is index by default). If you wanted to use the URL to pass parameters like that you would go to your function in the search controller and do:
print_r($this->input->get('q'));
This will print out "what_am_I_looking_for".
An easier approach in my opinion would be to:
1. Create a view called "search_view" with the HTML content you pasted above, and have the form "action" http://www.mysite.com/blog/index.php/test/search
Create a controller called "Test" that looks like the following:
class Test extends CI_Controller {
function search()
{
$search = $this->input->post('searchtext');
print_r($search);
}
public function display_search()
{
$this->load->view('search_view');
}
}
Visit http://www.mysite.com/blog/index.php/test/display_search in your browser. This should present you with the form you placed in search_view.php. Once the form is submitted, you should be sent to the search function and print out the variable $search, which will have whatever text you submitted on that form.
If this isn't what you were looking for then I am afraid I do not understand your question.
Im trying to preserve the user inputs from dynamic menu dropdown lists - I have an number of drowpdowns and a user input text field , when the user submits the form after selecting the options from the dropdowns.
I would like to be able to preserve the last choices made so the user does not have to reselect the options again when re posting the form with another value in the text field, i would also like this to work on errors as well ?
Im using ZF to validate the form.
i have tried the follwing code in the value attr of the option:
<option value="<?php if ($_POST && errors) {
echo htmlentities($_POST['CategoryID'], ENT_COMPAT, 'UTF-8');
}?>">Main Category</option>
But does not seem to work ?
I have a static options "Main Category" ect. which is what the form defaults to after submiting
can anyone help me on this one ??
Thanks in advance
I would highly recommend using Zend_Form. If that is not possible, I would next use Zend_View Helpers to build your HTML manually. Then you can use the formSelect in your view like this:
echo $this->formSelect('CategoryId', $selected, $attribs, array(
'main' => 'Main Category'
// ... other options
));
Where $selected variable equals to one of the following: posted value(s), default value(s), or is null and $attribs variable is simply attributes for the select element.
