Instead of cooking up your own PHP file and trying to bring in WordPress functionality, put the functionality inside of WordPress using the AJAX hooks that are designed to do that sort of thing. More info here: http://codex.wordpress.org/AJAX_in_Plugins
The documentation is well explicable of the topic, let’s have a look here https://developer.wordpress.org/reference/functions/apply_filters/. In your specific case my_filter is applied no matter what, even if there is no value it. To apply the filter only if is_array() you could insert a specific instruction directly into your filter like: function example_callback( $output ) { if(is_array($output)){ … Read more
Most probably the reason is that WordPress uses the default query on the homepage, which maybe the reason why you are getting an empty array for $_GET.
You’d need to declare $lineOne as global inside your function: global $lineOne; Messy way of coding though.
Not really. Anything that loads a template in WordPress is ultimately an include() or require() and only the variables in the caller function scope (and global scope of course) are passed on to the included file: function foo() { $bar = 1; include( ‘/path/to/template.php’ ); } $baz = 2; foo(); // template.php: echo $bar; // … Read more
if only the domain changes, you could try using relative urls: document.location=”/thank-you”; But if the domain you’re redirecting to is different than the page you’re on, a simple way to fix this problem would be to add a customizer value redirect_domain, and then make it a global variable in footer.php <script>var RedirectUrl=<?php echo get_theme_mod(redirect_domain);?></script> then … Read more
If it was me I’d not echo the text I’d make it a variable e.g. $additional_text = “” then at the end of the function return $additional_text;. if (have_posts()) : while (have_posts()) : the_post(); $additional_text=”<div class=”timeline”>”; $additional_text .= ‘<a href=”‘; $additional_text .= the_permalink(); $additional_text .= ‘”><h3>’; $additional_text .= the_title(); $additional_text .= ‘</h3></a>’; $additional_text .= ‘</div>’; … Read more
Creating variables on the fly like that is not needed. Just use an array instead. $myvars = []; inside your foreach loop you can: $myvars[] = array(‘title’=>$t,’image’=>$v); After your loop you can: //First title, First image echo $myvars[0][‘title’]; echo $myvars[0][‘image’]; //Second title, Second image echo $myvars[1][‘title’]; echo $myvars[1][‘image’]; This way you can always print_r($myvars) and … Read more
This requires a little bit of code to be placed in functions.php. If you want you can use a plugin like WP-Designer to do that. The WooCommerce filter ‘woocommerce_product_variation_title’ uses 4 arguments which are self-explanatory in the following piece of code which you can use in you functions.php. I tried it on my install and … Read more
This is more a generic PHP question than anything to do with WordPress, but I’d suggest setting the value in the constructor: class test { public $basicCols; public $optList = array( ‘one’ => ‘One’, ‘two’ => ‘Two’ ); function __construct() { $this->basicCols = array( array( ‘title’ => ‘KEY’, ‘field’ => ‘slug’, ‘options’ => $this->optList ), … Read more
