CodeIgniter - Upload an Image

CodeIgniter - Upload an Image

Copy the following code and store it at application/view/Upload_form.php. 
<html>
   <head> 
      <title>Upload Form</title> 
   </head>
   <body> 
      <?php echo $error;?> 
      <?php echo form_open_multipart('upload/do_upload');?> 
      <form action = "" method = "">
         <input type = "file" name = "userfile" size = "20" /> 
         <br /><br /> 
         <input type = "submit" value = "upload" /> 
      </form> 
   </body>
</html>

Copy the code given below and store it at application/view/upload_success.php

<html>
   <head> 
      <title>Upload Image</title> 
   </head>
   <body>  
      <h3>Upload an Image Success!</h3>  
   </body>
</html>

Copy the code given below and store it at application/controllers/upload.php. Create "uploads" folder at the root of CodeIgniter i.e. at the parent directory of application folder.

<?php
  
   class Upload extends CI_Controller {
 
      public function __construct() { 
         parent::__construct(); 
         $this->load->helper(array('form', 'url')); 
      }
  
      public function index() { 
         $this->load->view('upload_form', array('error' => ' ' )); 
      } 
  
      public function do_upload() { 
         $config['upload_path']   = './uploads/'; 
         $config['allowed_types'] = 'gif|jpg|png'; 
         $config['max_size']      = 100; 
         $config['max_width']     = 1024; 
         $config['max_height']    = 768;  
         $this->load->library('upload', $config);
   
         if ( ! $this->upload->do_upload('userfile')) {
            $error = array('error' => $this->upload->display_errors()); 
            $this->load->view('upload_form', $error); 
         }
   
         else { 
            $data = array('upload_data' => $this->upload->data()); 
            $this->load->view('upload_success', $data); 
         } 
      } 
   } 
?>

Make the following change in the route file in application/config/routes.php and add the following line at the end of file.

$route['upload'] = 'Upload';

Now let us execute this example by visiting the following URL in the browser. Replace the yoursite.com with your URL.

http://yoursite.com/index.php/upload

Django - Template System

Django - Template System 

Django makes it possible to separate python and HTML, the python goes in views and HTML goes in templates.

The Render Function
This function takes three parameters −

Request − The initial request.

The path to the template − This is the path relative to the TEMPLATE_DIRS option in the project settings.py variables.

Dictionary of parameters − A dictionary that contains all variables needed in the template. This variable can be created or you can use locals() to pass all local variable declared in the view.

Displaying Variables
A variable looks like this: {{variable}}. The template replaces the variable by the variable sent by the view in the third parameter of the render function.

hello.html
Hello World!!!Today is {{today}}
Then our view will change to − 
def hello(request):
from django.shortcuts import render
from django.http import HttpResponse 

from datetime import datetime

def index(request):
     return render(request, "index.html", {})
 
def hello(request):
   myDate = datetime.now()
   #formatedDate = myDate.strftime("%Y-%m-%d %H:%M:%S")
   #today = myDate.strftime("%A")
   today = myDate.strftime("%a")
   
   daysOfWeek = ['Mon', 'Tue', 'Wed', 'Thu', 'Fri', 'Sat', 'Sun']
   return render(request, "hello.html", {"today" : today, "days_of_week" : daysOfWeek})
   
   #return render(request, "hello.html", {"today" : today})
We will now get the following output after accessing the URL/myapp/hello −
Hello World!!!
Today is Sept. 11, 2016

Tag if
Just like in Python you can use if, else and elif in your template −
 
<html>
   <body>
      Hello World!!!<p>Today is {{today}}</p>
      We are
      {% if today == 'Sun' %}
      
      the Sunday day of month.
      {% elif today == 30 %}
      
      the last day of month.
      {% else %}
      
      I don't know.
      {%endif%}
   </body>
</html>
In this new template, depending on the date of the day, the template will render a certain value.
Tag for
Just like 'if', we have the 'for' tag, that works exactly like in Python. Let's change our hello view to transmit a list to our template −
 
def hello(request):
   today = datetime.datetime.now().date()
   
   daysOfWeek = ['Mon', 'Tue', 'Wed', 'Thu', 'Fri', 'Sat', 'Sun']
   return render(request, "hello.html", {"today" : today, "days_of_week" : daysOfWeek})
The template to display that list using {{ for }} −
 
<html>
   <body>
      Hello World!!!<p>Today is {{today}}</p>
      We are
      {% if today.day == 1 %}
      
      the first day of month.
      {% elif today == 30 %}
      
      the last day of month.
      {% else %}
      
      I don't know.
      {%endif%}
      
      <p>
         {% for day in days_of_week %}
         {{day}}
      </p>
  
      {% endfor %}
      
   </body>
</html>
And we should get something like −

Hello World!!!
Today is Sept. 11, 2015
We are I don't know.
Mon
Tue
Wed
Thu
Fri
Sat
Sun

Block and Extend Tags
A template system cannot be complete without template inheritance. Meaning when you are designing your templates, you should have a main template with holes that the child's template will fill according to his own need, like a page might need a special css for the selected tab.

Let’s change the hello.html template to inherit from a main_template.html.

main_template.html

 
<html>
   <head>
      
      <title>
         {% block title %}Page Title{% endblock %}
      </title>
      
   </head>
 
   <body>
   
      {% block content %}
         Body content
      {% endblock %}
      
   </body>
</html>
hello.html
 
{% extends "main_template.html" %}
{% block title %}My Hello Page{% endblock %}
{% block content %}

Hello World!!!Today is {{today}}


We are
{% if today.day == 1 %}

the first day of month.
{% elif today == 30 %}

the last day of month.
{% else %}

I don't know.
{%endif%}

{% for day in days_of_week %}
   {{day}}




{% endfor %}
{% endblock %}
