how can I over-ride wp-link-ajax WordPress

l.pirondini comments:

Hi Dbranes, Actualy I have the stuff I want showing in the box, but then when I scroll it does call "wp_link_query_args" and "wp_link_query" I just want to prevent these two actions from happening because at the time they happened my box is already set with what I want.

Dbranes comments:

ok, what about returning a <em>NULL </em> result, with:

add_filter( 'wp_link_query', '__return_null' );


l.pirondini comments:

I just tried that but it replaces the content inside the <ul> with
"<li class="unselectable"><span class="item-title"><em>No matches found.</em></span></li>"

The solution is preventing "wp_ajax_wp-link-ajax" from running at all but i couldn't find a way to achieve that

l.pirondini comments:

i meant "wp_ajax_wp_link_ajax"

Dbranes comments:

ok, so you need to unregister it with:

remove_action( 'wp_ajax_wp-link-query', 'wp_ajax_wp_link_query', 1 );


but the question is: inside what hook this is suitable.

But what about this hack:

add_action( 'admin_init', function(){
if( isset( $_POST['action'] ) && 'wp-link-ajax' == $_POST['action'] )
unset( $_POST['action'] );

} );


;-)

I can see the logic behind this hack but event with that the action still proceed and it still return a <li> No matches found.</li> replacing my li's

l.pirondini comments:

that's the function posing problem i guess http://wpseek.com/wp_ajax_wp_link_ajax/

The problem is that making it invalid by unset( $_POST['action']); seems to returns "No matches found."

Dbranes comments:

The ajax call is in the <em>/wp-includes/js/wplink.min.js</em> file:

$.extend( Query.prototype, {
ready: function() {
return ! ( this.querying || this.allLoaded );
},
ajax: function( callback ) {
var self = this,
query = {
action : 'wp-link-ajax',
page : this.page,
'_ajax_linking_nonce' : inputs.nonce.val()
};

if ( this.search )
query.search = this.search;

this.querying = true;

$.post( ajaxurl, query, function( r ) {
self.page++;
self.querying = false;
self.allLoaded = ! r;
callback( r, query );
}, 'json' );
}
});


l.pirondini comments:

is it possible to alter it by function.php so it wont be broken on update? That's so frustrating?

Dbranes comments:

Did you try to create a new node and add the result to that one, but keeping the old one hidden, i.e. this one: <em>#wp-link-wrap #most-recent-results ul</em> ?

Maybe it's possible to alter the <em>wpLink</em> object after initialization, I don't know.

It's the <em>process </em>method that's of interest:

process: function( results, params ) {
var list = '', alt = true, classes = '',
firstPage = params.page == 1;

if ( ! results ) {
if ( firstPage ) {
list += '<li class="unselectable"><span class="item-title"><em>' +
wpLinkL10n.noMatchesFound + '</em></span></li>';
}
} else {
$.each( results, function() {
classes = alt ? 'alternate' : '';
classes += this.title ? '' : ' no-title';
list += classes ? '<li class="' + classes + '">' : '<li>';
list += '<input type="hidden" class="item-permalink" value="' + this.permalink + '" />';
list += '<span class="item-title">';
list += this.title ? this.title : wpLinkL10n.noTitle;
list += '</span><span class="item-info">' + this.info + '</span></li>';
alt = ! alt;
});
}

this.ul[ firstPage ? 'html' : 'append' ]( list );
},


Dbranes comments:

ps: I'm just wondering what kind of list you're fetching, and why it can't be constructed into $results in the <em>wp_link_query </em>filter

Hey! your sugestion <blockquote>"Did you try to create a new node and add the result to that one, but keeping the old one hidden, i.e. this one: #wp-link-wrap #most-recent-results ul ?"</blockquote>

did the trick Thanks!

actualiy i am fetching data from a repeater field inside the current post (which is already fetched with an ajax call to populate a dropdown on each flexible content field), constructing it with "$results in the wp_link_query" seemed over complicated to me as i am putting much less information in, I guess that would have been a cleaner way.

Thanks for your help again any ways.
