Call jQuery function after all image are load

Some time we need to set equal height in our design. using below snippet we can easily call function or custom code.


// =============================================
// load portfolio list
// =============================================
function load_portfolio_list( post_length ) {

var category_id = jQuery(".portfolio-list").data('category_id');
jQuery( '.portfolio-ajax' ).addClass('loading');
jQuery.ajax({
type: "POST",
url: adminurl,
dataType: 'json',
data: { action : 'load_portfolio', post_length : post_length, category_id : category_id},
success: function (result){
jQuery('.portfolio-list .portfolio-ajax').remove();
jQuery('.portfolio-list .row').append(result.portfolio_list).imagesLoaded().then(function(){
equalheight('.portfilio-item');
});
},
error:function(){
alert("Error: There is some issue please try again.");
},
beforeSend:function(){
jQuery( '.portfolio-ajax' ).addClass('loading');
},
complete: function () {
jQuery( '.portfolio-ajax' ).removeClass('loading');
// Our code after load
}
});
}

below code are check image are loading after done function will return


// Fn to allow an event to fire after all images are loaded
jQuery.fn.imagesLoaded = function ($) {

// get all the images (excluding those with no src attribute)
var $imgs = this.find('img[src!=""]');
// if there's no images, just return an already resolved promise
if (!$imgs.length) {return jQuery.Deferred().resolve().promise();}

// for each image, add a deferred object to the array which resolves when the image is loaded (or if loading fails)
var dfds = [];
$imgs.each(function(){

var dfd = jQuery.Deferred();
dfds.push(dfd);
var img = new Image();
img.onload = function(){dfd.resolve();}
img.onerror = function(){dfd.resolve();}
img.src = this.src;

});

// return a master promise object which will resolve when all the deferred objects have resolved
// IE - when all the images are loaded
return jQuery.when.apply(jQuery,dfds);

}

WordPress file protected with user login

Some time we deed to give option to user download PDF, Doc file the protected with user login

On Download action code as like below


foreach($download_list as $list) {
$title = $list['title'];
$download = $list['download']['url'];

$path = get_home_url().'/';
$dir = '';
$resource_src = str_replace($path, $dir, $download);
$data = base64_encode($resource_src.'^'.get_current_user_id());

$url = get_site_url()."/download.php?file=$data";
?>
<li><a href="<?php echo $url; ?>" target="_blank"><?php echo $title; ?></a></li>
<?php
}

Create “download.php” file from root and add below code.


include('wp-load.php');

if( !get_current_user_id() )
{
wp_redirect(site_url('login/'));
exit;
}
$rew = explode('^',base64_decode($_GET['file']));
