I had earlier posted about the PHP undefined variable issue i was facing, but i managed to solve it somehow and after that there is a small element that is not working if i could be helped with. So it is an online noticeboard system for a school and it has a users dashboard, teachers, and the admin. So the users dashboard is okay except when a user uploads a picture, it says not found technically i was having issues regarding the image as a undefined variable, and now it says not found. Earlier it was all working well.  also there is something about the user's updating password, when they update a password, says successful then when u log out and log in with the old password, i yet manage to log in with both old and new passwords. what could be the issue there?
Below is attached a screenshot for how the user dashboard looks like.
so here is the user's view for dashboard_header page:
<!DOCTYPE html>

Hi Experts

Could you point if  phpCAS that uses API for authenticating users against a CAS server (WebSSO CAS) could be integrated at an existing Codeigniter project?

CAS - Central Authentication Server

I'm implementing a SSO (Single Sign-On)  funcionality to allow a web app conexion based on user id and  correspondent user's data obtained from LDAP (AD-Active Directory)

phpCAS

I'm planning to implement the SSO functionality at PHP Codeigniter's site index.php.

Thanks in advance!

I am using codeigniter as a framework, and it keeps logging users out.

- it ethier logs out randomly after a few minutes, or hours.
- it logs out when a user updates their order
- then as an admin if i get logged out randomly, and i log in into another account, it logs me back to the first account (the one i got randomly logged out from).

Whats the issue here? i found that i need to change the session time, but im not sure its working for me.

Hello!

We have an intranet that's behind a username/password page and one of our biggest struggles is search. We've implemented a basic search tool and it does okay at best. If searching for the word book, it'll return pages with the word book in it. However, it runs into issues when using multiple words, quotations, and does not rank the results for the user. Our intranet is using php and CodeIgniter. I looked around at codecanyon.net for php search engine scripts, but nothing really stuck out to me. Does an expert have a suggestion on what a good search solution might be for an intranet?

Hello! I'm trying to select some information from my database using drop-down lists, but when I pass my variables from my controller to the view, I get the "undefined variable" error. I can't understand why I get this error, because I've implemented other functions in a similar way and they worked. Also, I know the function in the model works, because I get my info using print_r.

This is my controller function.


This is my model function.


This is my view.
this is my view
This is the error I'm getting.

And this is what I get when I use print_r to see what my function in the controller is returning. It's correct,  just can't post it.

Please, help me!

This is what I am working with:

  • Window Server 2016
  • SQL Server 2017
  • IIS 10
  • Codeigniter 3

This is what I have done:

Installed IIS URL Rewrite 2.1

Modified the web.config file that is located in the application folder:

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
<system.webServer>
<rewrite>
    <rules>
        <rule name="Index">
            <match url="^(.*)$"/>
            <conditions>
                <add input="{REQUEST_FILENAME}" matchType="IsFile" negate="true"/>
                <add input="{REQUEST_FILENAME}" matchType="IsDirectory" negate="true"/>
            </conditions>
            <action type="Rewrite" url="index.php/{R:1}"/>
        </rule>                
    </rules>
</rewrite>
</system.webServer>

Modified the config.php file:

$config['base_url'] = 'http://10.10.0.4/portalci/';
$config['index_page'] = '';

Open in new window


Modified the autoload.php file:

$autoload['helper'] = array('url');

Open in new window


The results:

When I go to http://10.10.0.4/portalci/index.php it works fine. When I remove the index.php I get the following error: 403 - Forbidden: Access is denied.

Thanks in advance for your help!

Side note: I have spent the last 16 hours and reviewed hundreds of other post to try to resolve this myself.

I am working with some folk who are using Expression Engine Version 2. something.  They are considering upgrading to the latest version.  I know that version 2 and version 3 have a different directory setup.  Is there any definitive docs on how to upgrade with minimal pain? Tutorials? Plugins? How to videos?  I'm in the exploratory phase of this project and will appreciate any input on upgrading EE from 2.... to 3.0 - 4.0 and beyond!

I have an admin panel in codeigniter project.
There is a sidebar (<ul> <li>xxxxxx</li> </ul>) at the left and the content area in the right.
I store the content of the relevent option of sidebar in a variable , i.e the whole view and show inside a particular div in the right side content.
The functionality is working , but i want to do this without page load (i.e, by using ajax)
Here is the code in my master page
But it does not seem working

I shall be thankful if you kindly look into the issue

<script>
$(document).ready(function(){
 $('#a1').click(function(e){
            //alert("ok");
        e.preventDefault(); //To prevent the default anchor tag behaviour
        var url = this.href;
        //alert(url);
        $(".content").load(url);
        $('.content').load(<?php $this->load->view('admin/manage_student_form',$data, TRUE); ?>);
 });
 });
</script>

Hello,

I have piece of code here. I am trying to create something like a quiz application. In  <h4>Add question</h4> part, I can add a question if I want to and I store all the details I entered into the database by making an ajax call. Upon success, this piece of code gets replaced by the same code with other data so that the user can enter all the details. What I am trying to do is once I add a question in 'Add question' part, then I should be able to display it throughout the quiz. How can I do a post for new_questions in ajax and send it to the controller?

Can anyone suggest me how to do proceed with this?

Any kind of suggestion would be helpful.
   
<?php
foreach($substeps as $row) {
 ?>
 <div id='img_div'>
      <h2 id="stepslist_<?php echo $row->stepid;?>" class="step"><p><?php echo $row->stepname;?></p></h2>
      <img src='http://localhost/project/uploads/<?php echo $row->image; ?>'>
</div>
<?php } ?>
 <?php
      foreach($questions as $each){
      ?><br><br>
      <input type="text" name="questions[]" class='form-control' id="questions_<?php echo $each->questionid; ?>"  value="<?php echo $each->questionname; ?>" disabled/><br/>

The problem I'm facing is in the pagination part, while searching using the restaurant name, it retrieves all the records but while moving to the next page of the pagination link the total row count is set to 0, although retrieving the data values from backend.

In the else part of my controller res_search(search controller) the search is being carried out for using the location options, and its working fine.

**res_search (CONTROLLER)**

   
 public function index()
	{
	    $where_clause = "status = 'Y' ";
        $search = ($this->input->get("resTitle"))? $this->input->get("resTitle") : "NIL";
        $search = ($this->uri->segment(3)) ? $this->uri->segment(3) : $search;


       if($this->input->get("resTitle")!="")
       {
        $total_row_res=  $this->common_model->res_count($search,"") ;
        $limit = 3;        

        $config['base_url'] = base_url()."res_search/index/$search";
        $config['total_rows'] =  $total_row_res;
        $config['per_page'] = $limit;
        $config["uri_segment"] = 4;
        $choice = $config["total_rows"]/$config["per_page"];
        $config["num_links"] = floor($choice);   
    
        $config['full_tag_open'] = '<ul class="pagination">';
        $config['full_tag_close'] = '</ul>';
        $config['first_link'] = false;
        $config['last_link'] = false;
        $config['first_tag_open'] = '<li>';
        $config['first_tag_close'] = '</li>';
        $config['prev_link'] = 'Prev';
