我想知道除了使用regex之外，是否有一种简单的方法可以让top-stop-WordPress自动硬编码特征图像的高度和宽度属性。。。
因为我正在为我的项目使用灵活的网格（谁不是！）这导致了一些令人生厌的图像问题。
停止WordPress对img宽度和高度属性进行硬编码

您可以获取特色图像URL并手动将其添加到内容中，例如：
<?php
$image = wp_get_attachment_image_src( get_post_thumbnail_id( $post->ID ), \'thumbnail\' );
if ($image) : ?>
<img src="<?php echo $image[0]; ?>" alt="" />
<?php endif; ?>

可以通过过滤的输出来删除宽度和高度属性image_downsize 函数位于wp-includes/media.php. 要做到这一点，您需要编写自己的函数，并通过主题函数执行它。php文件或作为插件。
Example:
删除width 和height 属性。/**
* This is a modification of image_downsize() function in wp-includes/media.php
* we will remove all the width and height references, therefore the img tag
* will not add width and height attributes to the image sent to the editor.
*
* @param bool false No height and width references.
* @param int $id Attachment ID for image.
* @param array|string $size Optional, default is \'medium\'. Size of image, either array or string.
* @return bool|array False on failure, array on success.
*/
function myprefix_image_downsize( $value = false, $id, $size ) {
if ( !wp_attachment_is_image($id) )
return false;
$img_url = wp_get_attachment_url($id);
$is_intermediate = false;
$img_url_basename = wp_basename($img_url);
// try for a new style intermediate size
if ( $intermediate = image_get_intermediate_size($id, $size) ) {
$img_url = str_replace($img_url_basename, $intermediate[\'file\'], $img_url);
$is_intermediate = true;
}
elseif ( $size == \'thumbnail\' ) {
// Fall back to the old thumbnail
if ( ($thumb_file = wp_get_attachment_thumb_file($id)) && $info = getimagesize($thumb_file) ) {
$img_url = str_replace($img_url_basename, wp_basename($thumb_file), $img_url);
$is_intermediate = true;
}
}
// We have the actual image size, but might need to further constrain it if content_width is narrower
if ( $img_url) {
return array( $img_url, 0, 0, $is_intermediate );
}
return false;
}
image_downsize 挂钩：/* Remove the height and width refernces from the image_downsize function.
* We have added a new param, so the priority is 1, as always, and the new
* params are 3.
*/
add_filter( \'image_downsize\', \'myprefix_image_downsize\', 1, 3 );
/* Image sizes and alignments */
.entry-content img,
.comment-content img,
.widget img {
max-width: 97.5%; /* Fluid images for posts, comments, and widgets */
}
img[class*="align"],
img[class*="wp-image-"] {
height: auto; /* Make sure images with WordPress-added height and width attributes are scaled correctly */
}
img.size-full {
max-width: 97.5%;
width: auto; /* Prevent stretching of full-size images with height and width attributes in IE8 */
}
干杯

您可以使用post_thumbnail_html 筛选以删除属性：
function remove_img_attr ($html) {
return preg_replace(\'/(width|height)="\\d+"\\s/\', "", $html);
}
add_filter( \'post_thumbnail_html\', \'remove_img_attr\' );
functions.php 文件SO网友:Rogier van der Linde
您可以使用!important:
.wp-post-image {
width: auto !important; /* or probably 100% in case of a grid */
height: auto !important;
}

Best solution is to place jquery in footer
jQuery(document).ready(function ($) {
jQuery(\'img\').removeAttr(\'width\').removeAttr(\'height\');
});

CSS solution:
img[class*="align"], img[class*="wp-image-"] {
width: auto;
height: auto;
}
PHP solution:
这将防止在WP编辑器中的任何新添加介质上添加宽度/高度属性（通过“添加介质”）。仅供参考，这也可能会影响您的图像标题！function remove_widthHeight_attribute( $html ) {
$html = preg_replace( \'/(width|height)="\\d*"\\s/\', "", $html );
return $html;
}
add_filter( \'post_thumbnail_html\', \'remove_widthHeight_attribute\', 10 );
add_filter( \'image_send_to_editor\', \'remove_widthHeight_attribute\', 10 );

下面是一个简单的Javascript解决方案：
<script type="text/javascript">
jQuery.noConflict();
jQuery(document).ready(function($){
$(\'img\').each(function(){
$(this).removeAttr(\'width\')
$(this).removeAttr(\'height\');
});
});
</script>
$(\'.myspecificclass img\').each(function()

添加以下代码：（也适用于新的Gutenberg编辑器）
function disable_add_img_width_height( $value, $image, $context, $attachment_id ) {
if ($context === \'the_content\' || $context === \'the_excerpt\' || $context === \'widget_text_content\')
return false;
return $value;
}
add_filter( \'wp_img_tag_add_width_and_height_attr\', \'disable_add_img_width_height\', 10, 4 );
