I've been having some really crazy problems with my session userdata. It seems like it just stops showing up in my views page after making some edits, and I cannot figure out why. I am using notepadd++ to do my editing of the php files, so I just "undo" the edits, but then it still will not work. It makes no sense. I'm a novice so I will do my best to explain.
Website visitor fills out a form. The form is validated with the following function in the controller:
PHP Code:
function _mainsearchvalidate($searchtype)
{
$this->form_validation->set_rules('fname', 'First Name', 'required|trim|xss_clean');
$this->form_validation->set_rules('lname', 'Last Name', 'required|trim|xss_clean');
$this->form_validation->set_rules('age', 'Age', 'trim|xss_clean');
$this->form_validation->set_rules('city', 'City', '');
$this->form_validation->set_rules('state', 'State', 'required');
if($this->form_validation->run() == FALSE){
$data['search_type'] = $searchtype;
$this->themes->view('searches/home', $data);
} else {
$data['search_type'] = $searchtype;
$tempfname = $this->input->post('fname');
$templname = $this->input->post('lname');
$currentstate = $this->input->post('state');
$originalage = $this->input->post('age');
if (!empty($originalage)){
$numberofrows = rand(4, 7);
} else {
$numberofrows = rand(9, 25);
}
if (!empty($originalage) && ($originalage < 18)) {
$originalage = rand(18, 21);
}
elseif (!empty($originalage) && ($originalage > 102)) {
$originalage = rand(81, 101);
}
elseif (empty($originalage)) {
$mainpersonage = rand(18,78);
}
if (empty($mainpersonage)) {
$mainpersonage = $originalage;

In my views page, I am retrieving the userdata with this:
PHP Code:
<?= ucwords($this->session->userdata[1]); ?>
This WAS working until I made some edits. I undid the edits and it's still not working. My views page is giving me this error for each reference to the userdata:
A PHP Error was encountered
Severity: Notice
Message: Undefined offset: 1
Filename: searches/completed.php
Line Number: 11
I have been having some problems with this over the weekend while working on this page but I have always been able to "fix" it. Usually undoing edits will fix the problem, but one time when this happened undoing the edits didn't work. I fixed it by just switching these two lines of code around from the controller (near the bottom of what I posted for the controller's validate function code):
PHP Code:
$this->session->set_flashdata('type', $searchtype);
$this->session->set_userdata($resultsarray);
That doesn't make sense to me that switching those two lines of code suddenly fixed the undefined offset error, but it did. Naturally, that's the first thing I tried when this happened this time, but that did not work for me. I have run the code form the controller and the view page through a php syntax error error checker and both pages were clean. So I am out of ideas.
Also I would like to add some information regarding the setup of the views page. Right now I am testing this new functionality I am designing, which is based off existing functionality on the site, just another branch of it with more features, by using an if statement. Basically,
PHP Code:
<?php if($search_type == 'thesearchtype'): ?>
new functionailty here
old functionality here
I am doing this so I can test what I am designing while the visitors of the site can still use the old functionality.
Anytime the old functionality code is being used, I can refresh the search results page (the view page) and all of the information generated for the table stays the same. This is what I want. When search results are returned, those results should display any time a user refreshes the page. However, this does not happen with my new functionality. Instead, the search results on the views page return the results from the PREVIOUS search. Then when I refresh the page, the results from the intended search are displayed. So whenever the view page is displayed showing my search results from the new functionality, I must refresh the page again to display the actual search results. That is, if that damn undefined index error isn't getting in the way. Assuming I can get rid of the undefined index error and get my data to display on the views page, I will also need to address this problem where I need to refresh the page to see the actual results. I am not sure if there is a relation between these problems so I figured I would mention this.
