 How to filter news based on an XField |
 |
With the help of this code you can show news filtered by an XField. For example, show only news where the value of XField "mood" equals "happy".
 | | $xfieldfilter = array('mood', '=', 'happy'); |
In inc/show.news.php change this:
| | foreach ($query as $bg => $row){ |
to this:
| | if(isset($xfieldfilter)){
function xfield_filter($id){
global $xfieldfilter;
$return = true;
$path_to_xfields = '../data/xfields-data.txt';
$xfield_data = file($path_to_xfields);
foreach($xfield_data as $line){
$line_arr = explode("|>|", $line);
if($line_arr[0] == $id){
$all_xfields = explode("||", $line_arr[1]);
foreach($all_xfields as $single_xfield){
$my_xfield = explode("|", $single_xfield);
if($my_xfield[0] == $xfieldfilter[0]){
if($xfieldfilter[1] == '='){
if(trim($my_xfield[1]) == $xfieldfilter[2]){
$return = false;
}
}
if($xfieldfilter[1] == '<'){
if(trim($my_xfield[1]) < $xfieldfilter[2]){
$return = false;
}
}
if($xfieldfilter[1] == '>'){
if(trim($my_xfield[1]) > $xfieldfilter[2]){
$return = false;
}
}
if($xfieldfilter[1] == '<='){
if(trim($my_xfield[1]) <= $xfieldfilter[2]){
$return = false;
}
}
if($xfieldfilter[1] == '>='){
if(trim($my_xfield[1]) >= $xfieldfilter[2]){
$return = false;
}
}
}
else{
continue;
}
}
}
else{
continue;
}
}
return $return;
}
}
foreach ($query as $bg => $row){
if(isset($xfieldfilter)){
if(xfield_filter($row['id'])){
continue;
}
} |
How to use it:
Use something like this in your include code:
| | $xfieldfilter = array('my_xfield', '>', '5'); |
This will only show news which have an xfield with a value bigger than 5.
"my_xfield" is the name of the xfield, 5 is the value of the xfield and '>' is the operator. You can use "<", ">", "<=", ">=" or "=" as operators. Of course, if you don't have numbers in your xfield only "=" will work.
