Any Help, please.
I will rephrase it.
With the help of the ID, I just want to see whether the page with the ID is the Top Parent.
(At level 0)
If it is at the second level (Level 1), I want to return false.
For e.g.
Home Link 1
Home Link 2
Home Link 3
+++ Sub Link 31
+++ Sub Link 32
+++ Sub Link 33
Home Link 4
+++ Sub Link 41
+++ Sub Link 42
—+++ Sub Link 421
—+++ Sub Link 422
Now, if I get the Page ID of Home Link 3, I should have true, as it is the first parent. (And also true for Home Link 4 etc.)
But, if I get the ID for Sub Link 42 (which is also a parent), my code should return false, as it is not at the Top Level.
Many Thanks.
You might could use get_category_parents()?
It doesn’t return a boolean, but I think it would get the job done.
Thank you for both the answers.
But the first one tells whether the parent is category.
And the second one takes the $post handler to tell whether the current page is parent or not.
But I have only the ID and I cant proceed with the $post variable.
Within my code, which is as follows, I am able to found out by ID that whether the current page is Parent or not.
// Getting the Page ID in $sel_page_id.
foreach($include_array as $sel_page_id)
{
//Is it a parent
if(wp_list_pages("title_li=&child_of=$sel_page_id&echo=0" )):
echo $sel_page_id." is a parent";
//else it is not!
endif;
It works perfectly but the only problem, it gives me all the parents. For example, It will give me with respect to the upper example, the following Pages.
Home Link 1
Home Link 2
Home Link 3
Home Link 4
Sub Link 42 <—– I just dont want that, as it is not the Top Parent.
Please help .. 🙁
I did it with this code.
global $wpdb;
$prevalholder = array();
$arrctr = 0;
$matchFlag = false;
foreach($include_array as $sel_page_id)
{
$matchFlag = false;
if(wp_list_pages("title_li=&child_of=$sel_page_id&echo=0" )):
foreach($prevalholder as $previousValues)
{
// Check if this ID has any Parent. If it returns Zero, than there is no parent.
$idchecks = $wpdb->get_var( "select post_parent from $wpdb->posts where ID = $sel_page_id");
if ($idchecks == 0)
{
//It is a Top Parent
$matchFlag = false;
//echo "Not caught";
}
else
{
// It is not a Top Parent
$matchFlag = true;
//echo $sel_page_id . "CAUGHT " ;
}
}
if (!$matchFlag)
{
//The current ID is the Top Parent. Add it in the Array.
$prevalholder[$arrctr] = $sel_page_id;
$matchFlag = false;
$arrctr ++;
}
endif;
}
//$prevalholder Array now holds all the Top Parent IDs.
foreach($prevalholder as $pVal)
{
echo "<br />Top Parent ID : ". $pVal;
}
