Need help : posting content in sql database using php

[rajesh8619]

I have a form which created in codeigniter framework. I want to post html content into sql database using that form. I am using cleditor editor for text area.
when i was working in local host, this works fine. but in web server when i post content using this form, sometimes page not found error comes.

what 's the problem. i am struggling with this problem for the past one week.

i found the problem is not because of
1)post_max-size in php.ini
2)magic_quotes
3)editor

what are the other possiblities?
can any one help me?

Sounds like a path error in your code... can you post the relavent bits?

it's not path error..if path error means , it won't work all the time. some times only i get the page not found error.Any way i given the code below..

Codeigniter model function for this is

$title = strip_tags($barray['E_B_title']);
        $description = strip_tags($barray['E_B_desc'],'<p><a><br><strong><em><li><ul><ol><img><span><font><b><i><u><strike><sup><sub><font><h3><h4><h5><h6><hr><table><tr><td><tbody><tfoot><th><thead>');
        
        $url = $barray['E_B_url'];
        $v_url = $barray['E_B_vurl'];
        
        $javascript = '/<script[^>]*?>.*?<\/script>/si';
        $noscript = ''; 
        $remove_iframe = '/<iframe[^>]*?>.*?<\/iframe>/si';
        $remove_xml = '/<xml[^>]*?>.*?<\/xml>/si';
        
        $description = preg_replace($javascript, $noscript, $description); 
        $description = preg_replace($remove_iframe, $noscript, $description);
        $description = preg_replace($remove_xml, $noscript, $description);
        $description = rawurlencode($description);
        $tags = $barray['E_B_tags'];
        $date = time();
        $E_post_flag = $this->session->userdata('Post_flag');
        if($E_post_flag == $barray['E_add_post_flag']) {
            $data = array(
                        'component' => 'blog',
                        'type' => 'posted a blog',
                        'title' => $title,
                        'description' => $description,
                        'u_id' => $uid,
                        'date' => $date,
                        'c_id' =>$barray['E_B_catg'],
                        'no_of_comments' => 0,
                        'url' => $url,
                        'place_id' => $barray['E_B_place'],
                        'v_url' => $v_url,
                        'flag' => 's'
                        );    
            //$query = $this->db->insert('enx_blogs',$data);
            $query = $this->db->insert('activity',$data); 

i got description from cleditor editor and then i try insert all into the activity table.some times this works well. but sometimes i got page not found error.
