Hi,
I am following the CI tutorial called "Creating a blog in 20 minutes" and the "submit" button on my comment_view page does not work. (When I click the button it is supposed to take me to a 404 error page, but nothing happens)

I noticed that when the presenter of the tutorial views his page source, he gets this ():

Code:
&lt;html&gt;

&lt;head&gt;

&lt;title&gt;&lt;?php echo $title; ?&gt; &lt;/title&gt;

&lt;/head&gt;

&lt;body&gt;

<h1>&lt;?php echo $heading; ?&gt;</h1>

&lt;form method="post" action="http://www.example.com/CodeIgniter/index.php/blog/comment_insert

&lt;input type="hidden" name="entry_id" value="1" />

&lt;?php form_open('blog/comment_insert'); ?&gt;

&lt;?php form_hidden('entry_id', $this->uri->segment(3)); ?&gt;

<p>&lt;textarea name= "body" rows="10"&gt;&lt;/textarea></p>

<p>&lt;input type="text" name = "author" /&gt;&lt;/p>

<p>&lt;input type="submit" value="Submit Comment" /&gt;&lt;/p>

&lt;/form&gt;

&lt;/body&gt;

&lt;/html&gt;

But when I view my source code, I did not get these lines:

Code:
&lt;form method="post" action="http://www.example.com/CodeIgniter/index.php/blog/comment_insert

&lt;input type="hidden" name="entry_id" value="1" />

So I was wondering whether my form helper functions were working? I've included these helpers in the constructor as instructed:

Code:
$this->load->helper('url');

$this->load->helper('form');

So what is the problem?

If you include this code in your source:

Code:
&lt;?php form_open('blog/comment_insert'); ?&gt;

&lt;?php form_hidden('entry_id', $this->uri->segment(3)); ?&gt;

it will output:

Code:
&lt;form method="post" action="http://www.example.com/CodeIgniter/index.php/blog/comment_insert

&lt;input type="hidden" name="entry_id" value="1" />

If you need further help, post the source code you are actually using, not what you see in his tutorial.

You have to "echo" it.

Use:

Code:
&lt;?php echo form_open();?&gt;

I think that's all you need.

Or use '<?=' which is the same as '<?php' and 'echo' put together.
<?=form_open();?>

Err you havn't closed the closing tag on the <form> open tag??

You have

Code:
&lt;form method="post" action="http://www.example.com/CodeIgniter/index.php/blog/comment_insert

You want

Code:
&lt;?php print form_open('blog/comment_insert');?&gt;

Thank you very much tomdelonge. You were right, it works now because I forgot to use echo. The presenter is using the shorter form of the language and I am not (because I have not figured out how to get it to work).

Thanks for your reply mddd. When I typed that, it did not work in Chrome. How do I enable this?

Thanks adamp1, I don't know how I managed to leave that out in this post.

To use short tags, you will have to enable short tags by either adding
short_open_tag On

..to php.ini or vhost.

Or enable it in config/config.php:

Code:
$config['rewrite_short_tags'] = TRUE;

Latter will work even if short tags are disabled in PHP(but works only in view files).
When enabling rewrite_short_tags and short tags are disabled from serverside, CI will use eval to the view file's code. If you have errors in view files, debugging is a little harder as it will always tell you that some error occured on line 1(if I remember right).
