使用$ _GET数据自动填充插入表单

Question

I have a search form, where the user can insert in the same field the name of one or more authors.
I have this code:

Author<br /><input type="text" name="autore" value=<?php echo $_GET['autore'] ?> ><br/>

To automatically fill the Author field on the next page.

My problem is that if the user writes for example:

san, gli, tro

In the Author field I'll get only 'san,' , while I want 'san, gli, tro' .

How can I solve this?

Answer 1

What happens if you do:

Author<br /><input type="text" name="autore" value="<?php echo $_GET['autore'] ?>" ><br/>

(Notice quotes around the value attribute)
