Question about uwpqsf_result_tempt

Can you shows me all if your codes?

Here it is:

add_filter('uwpqsf_result_tempt', 'customize_output', '', 4);
function customize_output($results , $arg, $id, $getdata ){
$apiclass = new uwpqsfprocess();
$query = new WP_Query( $arg );
ob_start();
$result = '';
$i = 0;
if ( $query->have_posts() ) {
while ( $query->have_posts() ) {
$query->the_post();
global $post;
$i++;
include 'accommodation-search-results.php';
}
echo  $apiclass->ajax_pagination($arg['paged'],$query->max_num_pages, 4, $id, $getdata);
<input type="hidden" name="referrer" value="<?php echo $referrer; ?>">
} else {
echo  '<h2>'No results'</h2>';
}
wp_reset_postdata();
$results = ob_get_clean();
return $results;
}

$referrer value is not correct when used inside that function.

Thanks for your help!

When you use this :
$referrer = get_permalink();
Note that the get_permalink() need to be in the while loop, or you will need to provide an post ID.
But I don’t know why you want to put it into a hidden input field. It seem it does nothing in the function.

I tried

$referrer = get_permalink(get_the_ID());

and

$referrer = get_permalink($post->ID);

but none of them seem to work.

The hidden input field is included in a form which sends mail and needs to outup the referrer page permalink, that’s what I’m trying to do (in my previous post I didn’t write the whole form code which is very long, just the hidden input field).

You need to put the $referrer = get_permalink(get_the_ID()); in the while loop.

while ( $query->have_posts() ) {
}

And you will have the $referrer in each of the result post.

It doesn’t work.
It shows the permalink of one filtered post, not the container page which I need.

You can use the the container page id in the get_permalink() then.

The function is called by many different container pages.
I tried something like:

if (is_page ('first-container')) {
$referrer = get_permalink(1);
}
if (is_page ('second-container')) {
$referrer = get_permalink(2);
}
if (is_page ('third-container')) {
$referrer = get_permalink(3);
}

but still no success.

Since the it is an Ajax result template, you can’t get the global object like is_page().

However, you can try to add a hidden in the search form to indicate which page the form is displayed. And use it later in the result filter.

eg:

add_action('uwpqsf_form_bottom', 'page_identifier');
function page_identifier(){
  if (is_page ('first-container')) {
     $referrer = get_permalink(1);
   }
   if (is_page ('second-container')) {
     $referrer = get_permalink(2);
   }
    if (is_page ('third-container')) {
     $referrer = get_permalink(3);
   }
   echo '<input type="hidden" name="referrer" value="'.$referrer.'">';

}

Then in the result filter:

add_filter('uwpqsf_result_tempt', 'customize_output', '', 4);
function customize_output($results , $arg, $id, $getdata ){
$apiclass = new uwpqsfprocess();
$query = new WP_Query( $arg );
ob_start();
$result = '';
$i = 0;
if ( $query->have_posts() ) {
while ( $query->have_posts() ) {
$query->the_post();
global $post;
$i++;
include 'accommodation-search-results.php';
}
echo  $apiclass->ajax_pagination($arg['paged'],$query->max_num_pages, 4, $id, $getdata);

//here get the input into your hidden field
<input type="hidden" name="referrer" value="<?php echo $getdata['referrer']; ?>">

} else {
echo  '<h2>'No results'</h2>';
}
wp_reset_postdata();
$results = ob_get_clean();
return $results;
}

Note that you can access the input value via $getdata parameter. It is an array like $_GET or $_POST, so the referrer value would be $getdata['referrer']

Thanks a lot for your help!

It was enough to add the following code in functions.php:

add_action('uwpqsf_form_bottom', 'page_identifier');
function page_identifier(){
echo '<input type="hidden" name="referrer" value="'.get_permalink().'">';
}

and $getdata[‘referrer’] in my hidden input.

Thanks again.
