php request for images and fill blanks with a default image - php

Question

I have function that retrieves the images uploaded by each user. The limit per user is 5 images and I want to display a default image to fill the blanks upto 5 if they have less than 5 uploads. How can I achieve this?
function display_images() {
$imgs = get_images();
$html = '<div class="myImages">';
foreach($imgs as $img) {
$html .= '<div class="myImageContainer"><img src="'. $img .'"/></div>';
}
$html .= '</div>';
return $html;
}
function get_images() {
global $current_user;
get_currentuserinfo();
$args = array(
'author' => $current_user->ID,
'post_type' => 'attachment',
'post_mime_type' =>'image',
'post_status' => 'inherit',
'posts_per_page' => 5,
'orderby' => 'date'
);
$query_images = new WP_Query( $args );
$images = array();
foreach ( $query_images->posts as $image) {
$images[]= $image->guid;
}
return $images;
}

Answer 1

You have to check for current length of total images:
function display_images() {
$imgs = get_images();
$html = '<div class="myImages">';
foreach($imgs as $img) {
$html .= '<div class="myImageContainer"><img src="'. $img .'"/></div>';
}
if (count($imgs)<5) {
for($i=0; $i<(5-count($imgs)); $i++) {
$html .= '<div class="myImageContainer"><img src="MY_BLANK_IMAGE_LINK"/></div>';
}
}
$html .= '</div>';
return $html;
}
