我正在修改一个PHP Wordpress插件（Ebor模板构建器，构建在aqua页面构建器上）。
这是用于文本功能的PHP：
//set and create block
function __construct() {
$block_options = array(
'name' => 'Text',
'size' => 'span6',
'block_icon' => '<i class="fa fa-font"></i>',
'block_description' => 'Use to add Text,<br />HTML or shortcodes.'
);
//create the block
parent::__construct('aq_ebor_text_block', $block_options);
}
function form($instance) {
$defaults = array(
'text' => '',
'wpautop' => 0,
'code_display' => 0,
'textcenter' => 0
);
$instance = wp_parse_args($instance, $defaults);
extract($instance);
?>
<p class="description">
<label for="<?php echo $this->get_field_id('title') ?>">
Title (optional)
<?php echo aq_field_input('title', $block_id, $title, $size = 'full') ?>
</label>
</p>
<p class="description">
<label for="<?php echo $this->get_field_id('text') ?>">
Content
<?php echo aq_field_textarea('text', $block_id, $text, $size = 'full', true) ?>
</label>
</p>
<p class="description">
<label for="<?php echo $this->get_field_id('wpautop') ?>">
Disable Auto Paragraphs? <code>wpautop</code><br/>
<?php echo aq_field_checkbox('wpautop', $block_id, $wpautop) ?>
</label>
</p>
<p class="description">
<label for="<?php echo $this->get_field_id('textcenter') ?>">
Center Text?
<?php echo aq_field_checkbox('textcenter', $block_id, $textcenter) ?>
</label>
</p>
<?php
}// end form
function block($instance) {
extract($instance);
if( !(isset( $textcenter )) )
$textcenter = 0;
if( $textcenter == 1 )
echo '<div class="text-center">';
if($title)
echo '<h3 class="sub-heading">' . $title . '</h3>';
if($wpautop){
echo do_shortcode(htmlspecialchars_decode($text));
} else {
echo wpautop(do_shortcode(htmlspecialchars_decode($text)));
}
if( $textcenter == 1 )
echo '</div>';
}//end block
}//end class
这是用于后台视频功能的PHP（如您所见，它使用“fullheight”类）：
<?php
class AQ_Background_Video_Block extends AQ_Block {
//set and create block
function __construct() {
$block_options = array(
'name' => 'Background Video',
'size' => 'span12',
'block_icon' => '<i class="icon-picons-font"></i>',
'block_description' => 'Use to add Text<br />HTML or shortcodes.'
);
//create the block
parent::__construct('aq_background_video_block', $block_options);
}//end construct
function form($instance) {
/**
* Get all revsliders and load into an array.
*/
global $wpdb;
$table_name = $wpdb->prefix . 'revslider_sliders';
$sliders = $wpdb->get_results( "SELECT id, title, alias FROM $table_name" );
$amount = count($sliders);
$slider_choices = array('none' => 'None');
if( is_array($sliders) ){
for( $i = 0; $i < $amount; $i++ ){
$slider_choices[$sliders[$i]->alias] = $sliders[$i]->title;
}
}
/**
* Build defaults and instance for this block.
*/
$defaults = array(
'text' => '',
'slider' => 'none',
'type' => 'vimeo',
'image' => ''
);
$instance = wp_parse_args($instance, $defaults);
extract($instance);
$video_types = array(
'vimeo' => 'Vimeo',
'youtube' => 'Youtube'
);
/**
* Check if we found any sliders and display a select box or a message accordingly.
*/
if( $sliders ) :
?>
<p class="description">
<label for="<?php echo $this->get_field_id('slider') ?>">

<?php echo aq_field_select('slider', $block_id, $slider_choices, $slider) ?>
</label>
</p>
<?php else : ?>
<p class="description">Please Add Some Revolution Sliders if you wish to overlay content to this video.</p>
<?php endif; ?>
<p class="description">
<label for="<?php echo $this->get_field_id('type') ?>">
Video Source
<?php echo aq_field_select('type', $block_id, $video_types, $type) ?>
</label>
</p>
<p class="description">
<label for="<?php echo $this->get_field_id('title') ?>">
Video ID <code>e.g: 81676731 (Vimeo) or http://youtu.be/BsekcY04xvQ (Youtube)</code>
<?php echo aq_field_input('title', $block_id, $title, $size = 'full') ?>
</label>
</p>
<p class="description">
<label for="<?php echo $this->get_field_id('image') ?>">
Fallback Static Image <code>Mobile devices do not allow background video from a device level, choose a static background image instead.</code>

</label>
</p>
