Use PHP Variable as Value for Inline Style Property

[braddalton]

I've tried everything but cannot get this to work :

 

$cats = str_replace( '<a', '<a style="color: ' . $cat_color . ' "', get_the_category_list( ', ' ), $cats );

This doesn't work either :

$cats = str_replace( '<a', '<a style="color:{$cat_color}"', get_the_category_list( ', ' ), $cats );

The result i get is this :

 

element.style {

color: ($color);

}

Use outer double quotes to insert a variable into a string.

    $cat_list = "<a href='blah'>cat 1</a>, <a href='yadayada'>cat 2</a>";
    $cat_color = '#8F1FCF';
    
    $cat_list = str_replace('<a', "<a style='color:$cat_color'", $cat_list);

Works great when posts only contain 1 category link. Thanks.

The only problem i have now is the value for the first category is used to style every category link when the post contains more than 1 category.

$category_id = get_the_category( get_the_ID());
$cat_id      = get_category($category_id[0]->term_id);

$color = get_field( 'cat_color', $cat_id );

$cats = str_replace( '<a', "<a style='color:$color'", $list );

Should i start a new thread for this 2nd problem

If you do, tell us what your real problem is.

At present you are telling us a solution that isn't working - because it's the wrong solution, perhaps?

Yes, my problem is i can't work out how to use the value foreach custom field to color each category link when the post is assigned to multiple categories.

I think i need to use a foreach loop with an indexed Array with the category id foreach value returned as a string.

Or an associative Array so i can assign a category id foreach custom field value and return an array of colors which returns this array on the first post in the loop

array (size=4) 'red' => int 0 'green' => int 0 'blue' => int 0 'alpha' => float 1

And this on the 2nd 

array ()
  'red' => int 221
  'green' => int 153
  'blue' => int 51
  'alpha' => float 1

   

    $list = get_the_category_list();

    $category_id = get_the_category( get_the_ID());
    $id          = get_category($category_id[0]->term_id);

    $color       = get_field( 'cat_color', $id );
    
    foreach( $id as $color ) {

    $cats = str_replace( '<a', "<a style='color:$color'", $list );
    
    }
