Codeigniter passing variable to URL

Question

I have a list of posts and an edit link for each. When clicking edit it goes to a page where I can edit the specific post I clicked on. For this I will have to pull from the db the id of the post.

Would this be the correct way to do it?

<a href="<?php echo site_url("post/edit/$row->id"); ?>">Edit</a>

post is my controller, edit is my function, and $row->id should pull the id of the post.

Answer 1

Yes, it seems correct to do

<a href="<?php echo site_url("post/edit/".$row->id); ?>">Edit</a> 

Just make sure that your action method (edit in this case) accepts an argument with the post id that you need to fetch.

Answer 2

是的，这是正确的方法，就像SO中的编辑链接一样...只需确保在处理之前验证控制器中的ID

Answer 3

PHP won't interpret $row->id correctly within your string. you need to concatenate it at the end, EG: site_url("post/edit/".$row->id)

Answer 4

This is correct... Your code would throw an error

<a href="<?php echo site_url("post/edit/{$row->id}"); ?>">Edit</a>
