[英]Supersized.js how do you call JSON Encoded Data into the settings script
好吧,我是一个新手,但是去了:
我在wordpress网站上使用supersized.js为首页创建了完整尺寸的背景图像幻灯片,足以说明脚本已设置,并且现在可以正常工作了,我的下一个问题是使脚本使用wp_attachment
提取图像
在我的functions.php文件中,我创建了以下代码:
// Get all of the images attached to the current post
// These images will be used in the Supersized homepage gallery
function supersized_get_images($size = 'full') {
global $post;
$photos = get_children( array('post_parent' => $post->ID, 'post_status' => 'inherit', 'post_type' => 'attachment', 'post_mime_type' => 'image', 'order' => 'ASC', 'orderby' => 'menu_order ID') );
$results = array();
if ($photos) {
foreach ($photos as $photo) {
// get the correct URL for the selected size
$results['image'] = wp_get_attachment_url($photo->ID);
}
}
// encode into JSON format and pass to javascript supersettings.js
echo json_encode($results);
}
所以无论如何(我把echo
放进去了),因为我想看看它产生了正确的JSON格式。 echo的输出如下所示:
{"image":"http:\/\/pilarcorrias.secondvariety.org\/wp-content\/uploads\/0bcf5aa159739b260a77758c7d33699b.jpg"}
我认为这是对的。 超大型具有如下设置文件:
jQuery(function($){
$.supersized({
//Functionality
slideshow : 1, //Slideshow on/off
autoplay : 1, //Slideshow starts playing automatically
start_slide : 1, //Start slide (0 is random)
random : 0, //Randomize slide order (Ignores start slide)
slide_interval : 3000, //Length between transitions
transition : 1, //0-None, 1-Fade, 2-Slide Top, 3-Slide Right, 4-Slide Bottom, 5-Slide Left, 6-Carousel Right, 7-Carousel Left
transition_speed : 500, //Speed of transition

]
});
});
该文件的最后一行声明参数slides
,然后将图像引用传递给幻灯片。 现在,我检查了一下,并且幻灯片显示功能在没有URL和TITLE信息的情况下也能很好地运行,这意味着我只需要给它一个image
对象(这里是文件URI),这意味着我的JSON应该可以逐字记录。 现在,我知道我正在正确地编码PHP数组,如何将其放入上面的supersettings.js文件中。...到处都在搜索,但是没有找到可以用我的小脑袋来解释它的内容。 任何帮助将非常感激。
好东西! 此外,如果要从阵列中排除缩略图图像,请执行以下操作:
function supersized_get_images($size = 'full') {
global $post;
$thumb_id = get_post_thumbnail_id(get_the_ID()); // gets the post thumbnail ID
$photos = get_children( array('post_parent' => $post->ID, 'post_status' => 'inherit', 'post_type' => 'attachment', 'post_mime_type' => 'image', 'order' => 'ASC', 'orderby' => 'menu_order ID', 'exclude' => $thumb_id) );
否则,如果您不将php json与php混合到json等,则不可以; 如果您想要一种清晰的方法来解析json文件,请使用getJson进行解析。
jQuery(function($){
var urltojson = 'getjson.json';
$.getJSON(urltojson, function(photos){
$.supersized({
// Functionality
slide_interval : 5000, // Length between transitions
transition : 6, // 0-None, 1-Fade, 2-Slide Top, 3-Slide Right, 4-Slide Bottom, 5-Slide Left, 6-Carousel Right, 7-Carousel Left
transition_speed : 1000, // Speed of transition
// Components
slide_links : 'blank', // Individual links for each slide (Options: false, 'num', 'name', 'blank')
slides : photos
});
});
});
如果Json已满载,则将开始超大容量。 多数民众赞成在JavaScript中没有肮脏的php代码。
解决了这个问题,我很笨拙-我只是将脚本放入函数文件中,并将其命名为wp-footer挂钩,这使我能够在脚本本身中回显json变量。 对于尝试在Wordpress附件系统中使用超大尺寸的其他用户,这里是我完整使用的代码:
调用附件并创建json数组:
// Get all of the images attached to the current post
// These images will be used in the Supersized homepage gallery
function supersized_get_images($size = 'full') {
global $post;
$photos = get_children( array('post_parent' => $post->ID, 'post_status' => 'inherit', 'post_type' => 'attachment', 'post_mime_type' => 'image', 'order' => 'ASC', 'orderby' => 'menu_order ID') );
$results = array();
if ($photos) {
foreach ($photos as $photo) {
$keys [] = $photo->ID;
$captions [] = $photo->post_excerpt;
$descriptions [] = $photo->post_content;
// get the correct URL for the selected size
$results[] = array('image' => wp_get_attachment_url($photo->ID, 'full'), 'title' => '', 'url' => get_attachment_link($photo->ID));
}
}
return str_replace('\/', '/', json_encode($results));
}
好的,这样就可以得到图像,创建数组并正确设置URL的格式,以除去出现在http:\\ / \\ / www这样的转义斜杠的URL。 接下来,我不得不将脚本嵌入到body标签之前的页脚中,因此在这里:
function super_settings() { ?>
<script type="text/javascript">
jQuery(function($){
$.supersized({
//Functionality
slideshow : 1, //Slideshow on/off
autoplay : 1, //Slideshow starts playing automatically
start_slide : 1, //Start slide (0 is random)
random : 0, //Randomize slide order (Ignores start slide)
slide_interval : 3000, //Length between transitions
transition : 1, //0-None, 1-Fade, 2-Slide Top, 3-Slide Right, 4-Slide Bottom, 5-Slide Left, 6-Carousel Right, 7-Carousel Left
transition_speed : 500, //Speed of transition
new_window : 1, //Image links open in new window/tab
pause_hover : 0, //Pause slideshow on hover
keyboard_nav : 1, //Keyboard navigation on/off
performance : 1, //0-Normal, 1-Hybrid speed/quality, 2-Optimizes image quality, 3-Optimizes transition speed // (Only works for Firefox/IE, not Webkit)
image_protect : 1, //Disables image dragging and right click with Javascript
image_path : '/../../../slideshow/', //Default image path
//Size & Position
min_width : 0, //Min width allowed (in pixels)
min_height : 0, //Min height allowed (in pixels)
vertical_center : 1, //Vertically center background
horizontal_center : 1, //Horizontally center background
fit_portrait : 1, //Portrait images will not exceed browser height
fit_landscape : 0, //Landscape images will not exceed browser width
//Components
navigation : 0, //Slideshow controls on/off
thumbnail_navigation : 1, //Thumbnail navigation
slide_counter : 1, //Display slide numbers
slide_captions : 1, //Slide caption (Pull from "title" in slides array)
slides : <?php echo supersized_get_images(); ?>
});
});
</script>
<?php }
add_action('wp_footer', 'super_settings');
这会向wp_footer添加一个操作,该操作调用将脚本嵌入页脚的super_settings函数,您可以看到脚本的最后一行会回显supersized_get_images()
函数,并将键和值数组直接输出到javascript中。
我很高兴自己能回答这个问题,我很尴尬地问了这个问题,但我希望这对希望使用超大尺寸而不用在wordpress中使用自定义上传路径或与FTP混为一谈的人有所帮助-只需使用标准的wordpress帖子库。 ]您所要做的就是在要显示背景的页面上包含supersized.js和设置脚本。 中提琴! 如果有人有进步,他们可以建议将其张贴在这里。
