Add a dynamic CSS file with PHP

[PierreC]

Hi,

 

I'm currently writing an override for the CategoryController and I'm having issues adding a dynamically generated CSS file. My goal is to make subcategories icons' width adapt to the number of subcategories. In order to do that, I'm using a little "trick" that have worked in the past : I use a PHP file and declare the content as "text/css" in the header. Here is my php file dyn_categories.php :

<?php
header( 'content-type: text/css' );

$cat_count = $_GET['count'];
$width = 100/$cat_count.'%';
?>

#subcategories ul li {
    width: <?php echo $width; ?>;
}
?>

In my CategoryController override, I use this line in order to include the file :

$this->addCSS(array(
    _THEME_CSS_DIR_.'dyn_categories.php?count='.$nb_subcategories => 'all',
));

The string for the file name is good, as a simple "<?php echo _THEME_CSS_DIR_.'dyn_categories.php?count='.$nb_subcategories; ?> prints the expected path. However, the file is not included and the string "dyn_categories" cannot be found in the source of the generated page.

 

I tried to understand the addCSS and addMedia methods of FrontController and Controller, but I don't find any explanation.

 

Can anyone help me on this.

Thanks a lot

I don't know how to remove my post, but I just misunderstood a little detail and just found the solution by myself :

$this->addCSS(array(
    _THEME_CSS_DIR_.'dyn_categories.php?count='.$nb_subcategories => 'all',
), 'all', null, false);

The last parameter of 'addCSS' is checkpath, and if set to true (its default value) the files won't be included as there is no such file as 'dyn_categories.php?count=X'

 

Sorry for the useless post

Hi welcome to the forum first,

so thanks for sharing your solution.

 

And for your problem , probably could done in different ways. I was thinking that module

blockreinsurense have something similar

It might be a cleaner way to do it, but it does not offer the flexibility I want : I would have to define a width for each 'widthX' class (X being the variable).
