 |
|
hi,
My code is as follows:
$smarty->assign('customer_review',$rating);
$smarty->display("display.html");
'$rating' of integer type and it gets its value from database.
My problem is as follows:
for example suppose 'customer_review' get a value as 3. now i want to run a loop on my display.html page from 1 to value of 'customer review' and print 3 Stars. if it gets a value of 5 then print 5 stars using same loop.
How can i use 'for' or 'while' loop to achieve this.is it possible to use for or while loop using smarty in html file?
Any suggestion is highly appreciated.
Thanks in advance. |

Like this:
| Code: |
<style>
#stars img {
float: left;
margin-right: 2px;
}
</style>
<div id="stars">
{while $customer_review > 0}
<img src="img/star.png" alt="{$customer_review--} star">
{/while}
</div>

This is completely ill advised. embedding the same image on a page multiple times has no negative implications on performance. You load a single image, one request. done.
The alternative would be 10 images (for 10 stars). Do the math.

{'*'|str_repeat:$customer_review} |
that on the other hand even beats the {while} approach above. nice!

10 single Stars images - 10 Request's - One load - Request's cost time. |
Dude… I don't want to get offensive… so, let's try this first:
please create an html file and place 100 <img src="foo.jpg"> in it. make sure the foo.jpg exists. open the developer console of your favourite browser and look at the network tab. Please notice, that foo.jpg has been loaded exactly ONCE.
