So the framework is CodeIgniter 2.0.2. I have a form that has groups of fields that correspond to rows in a database. The names of the fields are in the format:

I am developing an API using CodeIgniter, and Phils RESTserver. I am trying to send a POST request containing special characters, but the string is not added to the database.

I use PHP/mySQL/CodeIgniter pretty heavily, writing sql statements to handle/manipulate data. I feel doing all that is primitive, and I've heard good things about MongoDB, schema-less database.

I using html2fpdf library to generate a pdf in codeigniter .I have some data in a varchar field like " What are your child’s academic strengths? " which is showing like " What are your child’s academic strengths? " . How I can show it as it is in the database .(I have tried htmlspecialchars_decode , html_entity_decode function but it not worked. )

I have a textarea and a button where i send the text via ajax to the database to post it. However when i post non-latin characters... it wont get them and it returns blank... if the text is in latin characters it works fine... my js code $.ajax({ type: "POST", url: www+"controller/postText", dataType: 'json', data: { input : input.val(), }, success: function(data) { return data; } }); my php code public function postText(){ $input = isset($_POST["input"]) ? trim($_POST["input"]) : ""; echo $input; return false; }

public function dcr() { $query = $this->db->query("SELECT * FROM church_repo"); foreach ($query->result() as $row) { $data = array('churchName' => $row->church_name, 'streetAddress' => $row->street_address, 'locationalState' => $row->locational_state, 'locationalZIP' => $row->locational_zip, 'locationalCountry' => $row->locational_country, 'locationalCity' => $row->locational_city, 'overseerAccountId' => $row->overseer_account_id, 'taxExemptionNumber' => $row->tax_exemption_number, 'accountStatus' => $row->status, ); $this->load->view('admin-request', $data); } } I...

I cannot seem to get CI's session library to function the way I want it to. Essentially, I am storing 2 different categories of data within the sessions. The data within the 2 categories may contain the same value. Right now my attempt to add a key => value pair to the session is failing, as it is only allowing 1 key => value pair to be associated with the array. It overrides itself each time I do a post. $arr = array( 'favorite_products' => array(), 'viewed_products' => array() ); $arr["favorite_products"][] = $fav_id; $this->session->set_userdata($arr); This is what the array looks when I print_r it: Array ( [favorite_products] => Array ( [4f1066c2b7fff] => 1648406 ) [viewed_products] => Array ( )) Am I doing something wrong, or is this just the way CI's session library works?

How can I keep checkboxes selected after the form has been submitted? I found the set_checkbox function in the Codeigniter User Guide, but it doesn't work. Form field code from the User Guide <input type="checkbox" name="mycheck" value="1" <?php echo set_checkbox('mycheck', '1'); ?> /> <input type="checkbox" name="mycheck" value="2" <?php echo set_checkbox('mycheck', '2'); ?> /> I also googled this and found a couple of workarounds, but they were based on previous versions of Codeigniter. And they were based on Form Validation, which isn't necessary for my form, because none of the fields are required. How can I retain the checkbox field value after the form is submitted? UPDATE : This question is not about form validation and errors. I want to retain the checkbox field value AFTER the page is reloaded. Is jquery a possibility?
