For those times you need to test the existence of a component or run some extra code on it before executing.
is_component()
Pass the id of the component to this function. It will return either true or false, depending on whether the component exists.
return_component()
Pass the id of the component to this function. It will return either the contents of the component in the form of a string or false, depending on whether the component exists.
Can I use it with the per page components function?
I do not think this is compatible with my per page components function, but I didn’t test it. I will not work on making it compatible if it isn’t because these two functions should be seen as extensions to the core functions and not as extensions to another extension.
is_component()
Pass the id of the component to this function. It will return either true or false, depending on whether the component exists.
Code:
function is_component($id) {
if (file_exists(GSDATAOTHERPATH.'components.xml')) {
$d = getXML(GSDATAOTHERPATH.'components.xml');
return count($d->xpath('//item[slug="'.$id.'"]'))>0?true:false;
}
}return_component()

Code:
function return_component($id) {
if (file_exists(GSDATAOTHERPATH.'components.xml')) {
$d = getXML(GSDATAOTHERPATH.'components.xml');
$v = $d->xpath('//item[slug="'.$id.'"]/value');
return !$v?false:stripslashes(htmlspecialchars_decode((string)$v[0],ENT_QUOTES));
}
