So I saw some posts on here about this like: https://wordpress.stackexchange.com/questions/46336/wp-redirect-function-is-not-working
I tried the solution to no avail. I wrote a php function that returns a permalink located in my functions.php file, the user enters a zip code, the form sends user to another page /locations where the function is called and the zip code is passed in:
function zip_search($userZip){
$args = array(
'posts_per_page' => -1,
'post_type' => 'Locations'
);
$wp_query = new WP_Query($args);
if( $wp_query->have_posts() ): while( $wp_query->have_posts() ) : $wp_query->the_post();
$zipField=get_field('zip_codes_services');
$zipString = $zipField . ', ';
$array = explode(', ' , $zipString); //split string into array seperated by ', '
foreach($array as $value) //loop over values
{
if($value==$userZip){
$post_id = get_the_ID();
$permalink=get_permalink($post_id);
return ($permalink); //print
}
}
endwhile;
wp_reset_postdata();
endif;
}
Search form on my main page looks like this:
<form action="/locations" method="get">
<input class="form-control search-input"
autocomplete="off"
name="zipcode"
type="text"
value=""
placeholder="Enter Zip Code" />
</form>
<input type="submit" />
Then in my /locations page I call my function to get a permalink and the wp_redirect function to redirect to the outputted permalink like this:
<?php
$zipcode = ( isset($_GET['zipcode']) ? $_GET['zipcode'] : '');
echo zip_search($zipcode);
$url = zip_search( $zipcode );
wp_redirect($url);
exit();
?>
However when I try to search I get this error:
Warning: Cannot modify header information - headers already sent by (output started at /srv/bindings/bdc12884a5a545f1b029665fb0fc0d35/code/wp-includes/class.wp-styles.php:225) in /srv/bindings/bdc12884a5a545f1b029665fb0fc0d35/code/wp-includes/pluggable.php on line 1219
Am I calling this function in the wrong place? Has anyone run into this issue in the past?
