Question

observe the code

if($line[$x]==1 and !empty($cat_ids[$x]))
    array_push($cat1,$cat_ids[$x]);
    elseif($line[$x]==1 and $cat_ids[$x]="")
    array_push($cat1,"id not allocated");

$line[$x] contains 1 and $cat_ids[$x] contains the id.

when the id is empty, i want to push “id not allocated” into the array at that particular $line[$x]. Please help me…

the code i written is skipping the empty field instead of printing ‘id not allocated’

Answer 1

Try changing

elseif($line[$x]==1 and $cat_ids[$x]="")

to

elseif($line[$x]==1 and $cat_ids[$x]=="")

as $cat_ids[$x]="" statement will assign the value null to $cat_ids[$x]
