Repeating an image according to a value from the database - El Forum - 03-20-2011

[eluser]victorche[/eluser]
I have a simple problem, which makes me crazy since yesterday. Let me show you the code:
Code:
$rows = $this->users->all_users(); // This gives me an array of all users.
One of the values here is the user rating, which is a round value from 1 to 10.
I just want to display a smile emoticon for the rating, instead of a number.
So, for example if an user has rating 8, I want to display one .gif 8 times. Like this (view file):
Code:
{rows}
<p>Username: {username}</p>
<p>Rating: {rating}<img src="emoticon.gif" />{/rating}</p>
{/rows}
Right now, I can display the rating as a number with this view:
Code:
{rows}
<p>Username: {username}</p>
<p>Rating: {rating}</p>
{/rows}
So, how can I make {rating} to become an array, which can repeat the image as many times, as the actual rating value?

Please, help me... As this makes me really crazy Sad

One more thing ... I know, I can replace the rating number with the images, using jQuery for example. But I want to manage with this in the code. Controller side, I mean.
So how can I repeat one image, when I have the repeating value from the database?

Please, give me a hint...

I don't think you can do that with pseudo-variables (template parsing). You will have to use straight PHP.

Code:
&lt;?php
foreach($rows as $row)
{
    ?&gt;
    <p>Username: &lt;?php echo $row['username']; ?&gt;</p>
    <p>Rating: &lt;?php
    for($i=0; $i<$row['rating']; $i++)
    {
        ?&gt;<img src="emoticon.gif" alt="" />&lt;?php
    }
    ?&gt;</p>
    &lt;?php
}
?&gt;

That's strange, I thought it would be really easy task. Anyway, thanks for your help! Maybe someone else can give a hint here...

The template parser class is very basic. All it can do is output variables, and loop through arrays. It cannot loop through a certain number as you want it to do. You will have to use straight PHP rather than pseudo-variables, as I suggested above.

Really thanks! This was a really useful information. And because I don't want php code in my templates... I found another solution. Thanks again!
