I have a portfolio that shows 3 rows of images in one page.
it is called portfolio.php.
I want to make it so when you will click on next button, it will go to the next page (portfolio2.php) with the same content, just different image URLs and rename that page to portfolio.php?page=2
but without using a pagination script.
Is there a way to change that pages name without using any advanced PHP script for paging?
Some friend told me to do this way:
<?php
// Get the page ID
$page_id = $_GET['page'];
// Create the page string
$page_string = "images_page" . $page_id . ".php";
// Include the page
include($page_string);
?>
But im not to sure how as I am getting Internal server error with this script.
Is there any way to rename a specify page to something like portfolio.php?page=2 ? something like (location: ) or something..
I want to do it this way because I am really clueless with PHP.
Thank you.
You can do it like this....
if(isset($_GET['page']) && $_GET['page'] != '') {
$pageno = $_GET['page']; /* Sanitize Here */
} else {
/* You can redirect user to home page */
}
if(isset($pageno)) {
if($pageno == '1') {
/* Page 1 content */
} elseif($pageno == '2') {
/* Page 2 content */
}
}
Note:- Always sanitize your data

I have a file named friend.php and I want change the friend.php content doing this:
friend.php?content=1, friend.php?content=2
Searching on google I can find change elements from url but I want change the content complete for example have content1.php, content2.php... but show that only doing this with the url.
Access this using $_GET superglobal:
<?php
if ($_GET["content"] == "1") {
// show content1.php
} else if ($_GET["content"] == "2") {
// show content2.php
}
?>
I have this code in my header.php to change the website's logo based on the page's slug:
$logo_img = 'default';
if (is_page('brookside')) {
$logo_img = 'brookside';
} elseif (is_page('hilltop')) {
$logo_img = 'hilltop';
} elseif (is_page('reserve')) {
$logo_img = 'reserve';
}
Which works great. However, the pages a need to change the logo are query string URL, so they don't have slugs. I was able to add a unique class to each page. My question is:
How do I translate that code to "if a page has "x" class? So, what function should I use instead of is_page?
Any help would be very appreciated!
Thanks!
You can use:
if($_GET['ct_additional_features'] == 'brookside') {
$logo_img = 'brookside';
}
You could use get_class that outputs the Class Name and there solve your if with what are you saying
I have set category page my default home page.But now i want to show CMS(Home page) for not logged in user while for logged-in i want to show category page.Means how i can set logic that can load both cms pages. How can i do that ? Thanks for any help in advance
<?php if(!Mage::getSingleton('customer/session')->isLoggedIn()): ?>
load->category page
<?php else: ?>//If user is NOT logged in
Load home page default one
<?php endif; ?>
IF you want only to check condition on home page .You can do like this .Change little bit code for CMS controller like this :
class Mage_Cms_IndexController extends Mage_Core_Controller_Front_Action
{
public function indexAction($coreRoute = null)
{
if(Mage::getSingleton('customer/session')->isLoggedIn())
{
Mage::app()->getFrontController()->getResponse()->setRedirect(Mage::getUrl('catalog/category/view/id/3'));
}else{
$pageId = Mage::getStoreConfig(Mage_Cms_Helper_Page::XML_PATH_HOME_PAGE);
if (!Mage::helper('cms/page')->renderPage($this, $pageId)) {
$this->_forward('defaultIndex');
}
}
}
Try and inform me about results.Hope this will solve your issue
This might work in your case :
// condition depending on login status of user
if(!$this->helper('customer')->isLoggedIn())
{
Mage::app()->getFrontController()->getResponse()->setRedirect(Mage::getBaseUrl());
die();
}
else
{
Mage::app()->getFrontController()->getResponse()->setRedirect(Mage::getUrl('YOUR_CATEGORY_URL'));
die();
}
IF above doesn't work, try this :
$sessionCustomer = Mage::getSingleton("customer/session");
if($sessionCustomer->isLoggedIn()) {
Mage::app()->getFrontController()->getResponse()->setRedirect(Mage::getUrl('YOUR_CATEGORY_URL'));
} else {
Mage::app()->getFrontController()->getResponse()->setRedirect(Mage::getBaseUrl());
}
I am trying to submit a EDIT form which edits Users Academics Details,
These Details have unique id in DB and my Code in Short Looks like below :
class edit extends ci_controller
{
function user_academics($id = NULL)
{
if(isset($id) == FALSE) //if link is ./edit/user_academics
{
$id = NULL;
$link = site_url('profile');
show_error("Invalid Page Request! <a href='$link' Go to Profile </a>");
}
$user_id = $this->session->userdata('user_id');
$data['fill'] = $this->edit_model->get_user_academics($id);
if($user_id != $data['fill']['user_id']) // check if logged in user is accessing his record or others
{
$link = site_url('profile');
show_error("This is an Invalid Request ! <a href='$link'>Go to Profile </a>");
}
else // actual work starts here
{
$this->session->set_flashdata('ua_id',$id); // update_academics will get this data
$this->load->view('edit/edit_3_view',$data);
}
}
function update_academics()
{
$ua_id = $this->session->flashdata('ua_id'); // flash data used here .
if( !$ua_id )
{
show_error('Sorry, This request is not valid!');
}
$academics = array(
// All post values
);
$this->edit_model->update_user_academics($academics,$ua_id);
//print_r($academics);
redirect('profile');
}
}
Now the problem is
- If I open two different records to edit, then It will set only one Session Flash value.
- And No matter what I edit , the existing values of the last flash value gets updated.
Please Suggest me another way or Correct me if I am wrong in above code . Thanks
save that flashdata in array, like:
$myArr = array('value 1', 'value 1');
//set it
$this->session->set_flashdata('some_name', $myArr);
And in view:
$dataArrs = $this->session->flashdata('some_name');
//loop thru $dataArrs to show the flashdata
Flash data is simply like variable which is available only in next request, you can bypass this behavior by using two different keys with record id in it, so that when you use flash data for showing message you can access key with particular record id.
I have a page with URL http://arslan/admin/category/index/0/name/asc/10 in Codeigniter.
In this URL, the uri_segment start from 0. This (0) is the default search value, name and asc are the default sort field and order, and 10 is the pagination index.
Now if I move to an add page with URL (http://arslan/admin/category/add/)
similarly like above "add" is the current function.
Now if i want to go back through a link to back page... How can I divert the user back? I can't make the URL go back.
Can somebody help me please?
I am not sure if i understand the question correctly, if not please ignore my answer, but I think you want a link to "go back to previous page", similar to the back-button in a web browser.
If so you could use javascript to solve this by simply using this line:
Go back
I extend the session class by creating /application/libaries/MY_Session.php
class MY_Session extends CI_Session {
function __construct() {
parent::__construct();
$this->tracker();
}
function tracker() {
$this->CI->load->helper('url');
$tracker =& $this->userdata('_tracker');
if( !IS_AJAX ) {
$tracker[] = array(
'uri' => $this->CI->uri->uri_string(),
'ruri' => $this->CI->uri->ruri_string(),
'timestamp' => time()
);
}
$this->set_userdata( '_tracker', $tracker );
}
function last_page( $offset = 0, $key = 'uri' ) {
if( !( $history = $this->userdata('_tracker') ) ) {
return $this->config->item('base_url');
}
$history = array_reverse($history);
if( isset( $history[$offset][$key] ) ) {
return $history[$offset][$key];
} else {
return $this->config->item('base_url');
}
}
}
And then to retrieve the URL of the last page visited you call
$this->session->last_page();
And you can increase the offset and type of information returned etc too
$this->session->last_page(1); // page before last
$this->session->last_page(2); // 3 pages ago
The function doesn't add pages called using Ajax to the tracker but you can easily remove the if( !IS_AJAX ) bit to make it do so.
Edit:
If you run to the error Undefined constant IS_AJAX, assumed IS_AJAX
add the line below to /application/config/constants.php
define('IS_AJAX', isset($_SERVER['HTTP_X_REQUESTED_WITH']) && strtolower($_SERVER['HTTP_X_REQUESTED_WITH']) == 'xmlhttprequest');
There are two ways to solve your problem: First you could place a link that is using the javascript back-function onclick, like this ...
go back
... or you always save the current full page url into a cookie and use that for generating the back link - a helper could look like this (not tested) ...
/**
* save url to cookie
*/
if(!function_exists('urlhistory_save'))
{
function urlhistory_save()
{
$CI =& get_instance();
$CI->load->library('session');
$array = array(
'oldUrl' = $CI->session->userdata('newurl'),
'newurl' = $CI->uri->uri_string()
);
$CI->session->set_userdata($array);
}
}
/**
* get old url from cookie
*/
if(!function_exists('urlhistory_get'))
{
function urlhistory_get()
{
$CI =& get_instance();
$CI->load->library('session');
return $CI->session->userdata('oldurl');
}
}
In your controller you would use urlhistory_save() to save the current URL and in the view youd could use urlhistory_get() to retreive the old address like this:
<a href="<?php echo base_url().urlhistory_get(); ?>go back</a>
The most simplest way to redirect to your previous page , try this it work for me
redirect($this->agent->referrer());
you need to import user_agent library too $this->load->library('user_agent');
You can create a Session to go to back page as:
$this->session->set_userdata('ses_back_jobs','controller
name'.array_pop(explode('controller name',$this->input->server('REQUEST_URI'),2))); //Back page
Then if u want to redirect to some page use it:
redirect($this->session->userdata('ses_back_jobs'));
or use it to the anchor.
