Passing parameters from view to controller in CodeIgniter

Question

I have this basic question

Is this :

<a href="userconsole/indivstore/<?php echo $obj->store_id; ?>/">
<?php echo $obj->title; ?></a> 

Different from this:

<a href="/userconsole/indivstore/<?php echo $obj->store_id; ?>/">
<?php echo $obj->title; ?></a>

Or is there no difference?

(I am using CodeIgniter at present)

Answer 1

Unless I've missed something, the only difference (and there is at least one difference) is in the HTML, not in the PHP per se.

The second one has a link that starts with a / , so that means it points to the link at

http://yoursite.tld/userconsole/etc

the first one points to /userconsole/etc relative from the place you call it. So if you are in the dir /yourpath , it will point you to http://yoursite.tld/yourpath/userconsole/etc

Answer 2

Lets say ur on www.somesite.com/url/

With

<a href="userconsole/indivstore/<?php echo $obj->store_id; ?>/">
<?php echo $obj->title; ?></a> 

Ur Going to www.somesite.com/url/userconsole/indivstore/

With

<a href="/userconsole/indivstore/<?php echo $obj->store_id; ?>/">
<?php echo $obj->title; ?></a>

Here is the / important! your going back to your root path that means www.somesite.com . The result: www.somesite.com/userconsole/indivstore/

So at all its realative vs absolute path.

Answer 3

The first link has a relative path to the actual page you are visiting, but the second page has the absolute path so:

If you are at: http://example.com/something/other-thing

In first case the next url will be: http://example.com/something/other-thing/userconsole..etc In the second case the next url will be: http://example.com/userconsole..etc

Answer 4

<a href="userconsole/indivstore/<?php echo $obj->store_id; ?>/"> is relative URL so if you are on http://host/site/current-page it will point to http://host/site/current-page/userconsole/indivstore/<?php echo $obj->store_id; ?> http://host/site/current-page/userconsole/indivstore/<?php echo $obj->store_id; ?> which is wrong

<a href="/userconsole/indivstore/<?php echo $obj->store_id; ?>/"> is absolute URL so if you are on http://host/site/current-page it will point to http://host/userconsole/indivstore/<?php echo $obj->store_id; ?> http://host/userconsole/indivstore/<?php echo $obj->store_id; ?> which is wrong if your site is under a sub folder.

the correct way to generate URL with codeigniter is using site_url() helper please check http://codeigniter.com/user_guide/helpers/url_helper.html
