<p>another question again regarding codeigniter, here a few details: </p> <p>view page: </p> <pre><code><?php if (isset($error)){echo $error; } ?> <form action="<?php echo site_url('mem_posting/post');>" method="post"> <input type="text" name="fname"> some fields goes here... </form> </code></pre> <p>controller page(mem_posting): </p> <pre><code>public function post_form() { $this->load->view('header'); $this->load->view(form_page); } public function post() { $post_data=array( 'mem_id'=>$this->input->post('mem_id'), //other inputs... ) $this->load->model('member_model'); if ($this->member_model->check_member($post_data)===true) { //row exist // **i would like to load the same page but // **with error message "like already exist". }else{ $this->member_model->inset_member($post_data); } } </code></pre> <p>model page: </p> <pre><code>public function insert_member($post_data=array()) { extract($post_data); $this->db->where('member_id', $member_id); $this->db->insert('membership', $post_data); } public function check_member($post_data=array()) { extract($post_data); $this->db->select('mem_id'); $this->db->where('mem_id', $mem_id); $query = $this->db->get('membership'); if ($query->num_rows() > 0){ return true; }else{ return false; } } </code></pre> <p>as you can see the view page contains the form, now what i would like to achieve is to echo an error like 'already exist' so i dont have to code another $this->load->view('post_form') inside the if statement.</p> <p>thank you in advance..</p>

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
