How to send multiple parameters in echo based on isset
I have pagination code that is working perfect when filters are not set. However when i use filters on my page it displays every product but unlimited number of pages are shown with nothing on it after products are done. I checked if it would work if i send filter like :
if(isset($brand)){
echo " <a href='{$_SERVER['PHP_SELF'}}?currentpage=$nextpage&brand=$brand'>></a> "
}else{
echo " <a href='{$_SERVER['PHP_SELF'}}?currentpage=$nextpage'>></a>
}
but this is not efficient way to do this because i will have to check for 20 filter. Also I tried with string adding and adding it later to <a> but it is not working like:
$filters;
if(isset($brand)){
$filters .= "&brand=".$brand;
}
So my question is: Is there a way to check in echo if filters are set and send them all to next page(like: brand, color, size..).

Use http_build_query to build an HTTP query string from an array of values. When building your array, use the null coalescing operator to avoid notices about using undefined variables.
$filter_array = [
"currentpage" => $nextpage,
"brand" => $brand ?? "",
"color" => $color ?? "",
"size" => $size ?? "",
// and the rest of your variables
];
$query = http_build_query($filter_array);
echo sprintf('<a href="%s?%s">></a>', $_SERVER["PHP_SELF"], $query);
Or, for old unsupported PHP versions:
$filter_array = [
"currentpage" => $nextpage,
"brand" => isset($brand) ? $brand : "",
"color" => isset($color) ? $color : "",
"size" => isset($size) ? $size : "",
// and the rest of your variables
];
$query = http_build_query($filter_array);
echo sprintf('<a href="%s?%s">></a>', $_SERVER["PHP_SELF"], $query);

add all the filters into an array first
$filters = array();
$filters['brand'] = $brand;
$filters['color'] = $color;
$filters['size'] = $size;
loop through the filters array to make params string
$anchor_tag_params = "";
foreach($filters as $key => $value)
{
$anchor_tag_params .= "&".$key."=".$value;
}
and then just append the params string to the anchor tag href
$anchor_tag_html = '<a href="'.$_SERVER['PHP_SELF'].'?currentpage='.$nextpage.$anchor_tag_params.'"></a>';
