CodeIgniter Fatal error: Allowed memory size of by

问题:

I'm getting this Fatal Error Message in my codeIgniter, I've already tried some answers which has the same question.

I've already set my php.ini

    max_execution_time = 300
    max_input_time = 600
    memory_limit = 128M

But still I'm getting the same Fatal error message, I don't know if the problem is in my code or in php settings.

Here are some my of codes in controller:

public function blog(){
    $this->load->model("blog_model");
    $data["title"] = "CodeIgniter Projects - Blog";
    if($this->getLastUrl() == 'blog'){
        $data["result"] = $this->blog_model->getBlogs();
        $this->load->view("view_blog", $data);  
    }else{
        $blog_name = $this->getLastUrl();
        $data["result"] = $this->blog_model->getBlogDetails($blog_name);
        $data["comment"] = $this->blog_model->getBlogComments($blog_name);
        $this->load->view("view_blog_details", $data);
        //check for reply
        $url =$_SERVER['REQUEST_URI'];
        $getLast = explode("/", $url);
        $last = end($getLast);
        if($last == 'reply'){
            $this->load->library('form_validation');
            $this->form_validation->set_rules('name', 'Name', 
                'trim|required|min_length[4]|xss_clean');
            $this->form_validation->set_rules('message', 'Comment', 
                'trim|required|min_length[4]|xss_clean');
            $this->form_validation->set_rules('email', 'Email Address', 
                'trim|required|valid_email');

            if($this->form_validation->run() == FALSE)
            {
                $this->blog();
            }
            else
            {
                $msg = 'Message sent.';
                $this->blog_model->addBlogComment();
                $this->blog();
            }
        }

    }
}

My main function is to add new comment in a blog, it works but it inserts duplicate data and I cant get rid of the fatal error message.

addBlogComment Function

    function addBlogComment(){
    $data=array(
    'blog_id'=> $this->input->post('blog_id'),
    'name'  => $this->input->post('name'),
    'email' => $this->input->post('email'),
    'message' => $this->input->post('message'),
    'created'   => date('Y-m-d H:i:s')
    );

    $this->db->insert('comment',$data);
    }

I just found out the wrong loop in my code. The loop will has no exit and it will turns back all over again.

if($this->form_validation->run() == FALSE)
{
      $this->blog();
}
else
{
      $msg = 'Message sent.';
      $this->blog_model->addBlogComment();
      $this->blog();
}

it will always return a false value so it will execute and execute no end of loop.

Try construct your controller like so:

public function blog( $blog_name = '', $action = '' ){

    $this->load->model("blog_model");

    // What if there is no blog name in the url
    if ( empty( $blog_name ) ) {

        // Load the list of blogs
        $data["result"] = $this->blog_model->getBlogs();
        $this->load->view("view_blog", $data);

    } else {

        // If the blog name in url exists and there is no action display the blog
        if ( !empty( $blog_name ) && empty( $action ) ) {

            $blog_name = $this->getLastUrl();
            $data["result"] = $this->blog_model->getBlogDetails( $blog_name );
            $data["comment"] = $this->blog_model->getBlogComments( $blog_name );
            $this->load->view("view_blog_details", $data);

        }
        // else If there is the action "reply" check if there is some post
        else if ( $action == 'reply' && $this->input->post( 'Comment' ) ) {

            $this->load->library( 'form_validation' );
            $this->form_validation->set_rules( 'name', 'Name', 'trim|required|min_length[4]|xss_clean' );
            $this->form_validation->set_rules( 'message', 'Comment', 'trim|required|min_length[4]|xss_clean' );
            $this->form_validation->set_rules( 'email', 'Email Address', 'trim|required|valid_email' );

            if($this->form_validation->run() == FALSE) {

                redirect( site_url( $blog_name ) );

            } else {

                $msg = 'Message sent.';
                $this->blog_model->addBlogComment();

                // Redirect to prevent F5 submitting duplicate data
                redirect( site_url( $blog_name ) );
            }
        }
    }
}
