Question

I would like to implement a “save” feature, which allows my users to save a particular entry that I have presented to them from my database. For example, if they see something they like, they can press the “save” button and it will save to a “bookmarks” page.

Here is my code:

<?php 

// Get all the data from the example table
$result = mysql_query("SELECT * FROM table WHERE item <> 0 ORDER BY id") 
or die(mysql_error());  

// keeps getting the next row until there are no more to get
$i = 10; 
while ($i > 0) {  
    $i--;
    $row = mysql_fetch_array( $result );
    if ($row['id'] != "" ) { 
?>

<!-- Some content in this div-->
<div class="content"> 
<img  src="<?php echo $row['logo']; ?>"/>
<?php echo $row['id']; ?>
</div>

<!-- This div will have the save icon that users can press --> 
<div class="save">
<img  src="images/saveIcon.png" />
</div>

<?php }} ?>

<div class="bookmarked"> 
Every single div that is labled as "content" that has been saved, will be displayed here. 
</div>

Question: How would I implement a feature to allow a user to add the particular ID from SQL (of the dynamically created content) to a cookie variable, so that it can be reproduced at a later time.

Answer 1

If I have understood your question correctly, you want a button which marks the related DIV, and stores this relation to cookies.

First of all, I would add the id of entry as class to the DIV. Then you’ll have the possibility to get the id easily via javascript (for further implementations).

To set the favorites via php, you should add a link to a new php script. This script sets the cookie, via the setcookie function in PHP.

In your bookmarked-DIV you would make the same while-loop as above, but check the ids with the values in the cookies. You can access cookies with $_COOKIE. Just show items, which are containing in the cookies.

This is a possible way of implementation.
