CodeIgniter notes #3

I often scribble down important notes and stuff I learn in a notebook, I prefer to use a traditional way of learning, using pen and paper. Here are some notes I jotted down.

1. Use var_dump($variable), this will outputs the variable to your screen. This is similar function to JavaScript’s console.log(variable).
2. This is a html file, there is a form, when I click the submit button, it will send a POST to submit.php, the variables can be accessed from the controller.
   XHTML

   <form method='post' action='index.php/submit'> <label name="password"> <label name="status"> </form>

   1 2 3 4

   <form method='post' action='index.php/submit'> <label name="password"> <label name="status"> </form>

   PHP

   $_POST['password'] $_POST['status']

   1 2	$_POST['password'] $_POST['status']

3. <?php echo base_url(); ?> outputs the base url of your website.
4. I noticed a lot of these patterns in the html code.
   
   PHP

   <?php if(isset($slideQuery)) && !empty($slideQuery)) { ?> <ul class="slides"> <?php foreach($slideQuery as $slide) { if($slide->slide_type == "bottom"){ continue; ?> <?php } } ?> <?php } ?>

   1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20

   <?php if(isset($slideQuery)) && !empty($slideQuery)) { ?>   <ul class="slides"> <?php foreach($slideQuery as $slide) { if($slide->slide_type == "bottom"){ continue; ?>   <?php } } ?>     <?php } ?>

5. Advice when looking at codeigniter website code for the first time, examine front page code part by part.
6. application/config/routes.php sets where the controller starts
7. Bill’s advice: Always make backup, in case batshit happens.
8. Web development is like game development, an artist/ designer gives the psd to the programmer, and the programmer program the website/ game.
9. Instead of using span6 and span6 (bootstrap) to make a row, use width:50%, float:left and width:50%, float:left.
10. Never use inline style, use CSS instead, you might have problems with responsiveness.
