我有一个主题,使用下面的代码将帖子显示为缩略图,但它以错误的比例(400px x 300px)裁剪它,我不知道是什么告诉它这样做。我将如何更改以 210px x 210px 生成的缩略图?
<?php
foreach($all_photo_arr as $key => $portfolio_item)
{
$cur_post++;
$image_url = '';
if(has_post_thumbnail($portfolio_item->ID, 'portfolio2'))
{
$image_id = get_post_thumbnail_id($portfolio_item->ID);
$image_url = wp_get_attachment_image_src($image_id, 'portfolio2', true);
$full_image_url = wp_get_attachment_image_src($image_id, true);
}
$last_class = '';
$line_break = '';
if(($key+1) % 4 == 0)
{
$last_class = ' last';
$line_break = '<br class="clear"/>';
}
$portfolio_link_url = get_post_meta($portfolio_item->ID, 'portfolio_link_url', true);
if(empty($portfolio_link_url))
{
$permalink_url = get_permalink($portfolio_item->ID);
}
else
{
$permalink_url = $portfolio_link_url;
}
$portfolio_item_class = 'one_fourth';
if(($key+1) % 4 == 0)
{
$portfolio_item_class.= ' last';
}
$pp_portfolio_image_height = 210;
?>
