您也可以尝试:

如果您只有一个尺寸的缩略图:

 $thumbnail = wp_get_attachment_image_src( get_post_thumbnail_id( $post->ID ) );
 

或者...如果您有多种尺码:

 $thumbnail = wp_get_attachment_image_src( get_post_thumbnail_id( $post->ID ), "size" );
 

请注意,wp_get_attachment_image_src()返回一个数组:url,宽度,高度,is_intermediate.

因此,如果您只想要图片网址:

 echo $thumbnail[0];

• https://developer.wordpress.org/reference/functions/wp_get_attachment_image_src/

You might also try:

If you only have one size thumbnail:

$thumbnail = wp_get_attachment_image_src( get_post_thumbnail_id( $post->ID ) );

Or...if you have multiple sizes:

$thumbnail = wp_get_attachment_image_src( get_post_thumbnail_id( $post->ID ), "size" );

Note that wp_get_attachment_image_src() returns an array: url, width, height, is_intermediate.

So if you just want only the image url:

echo $thumbnail[0];

• https://developer.wordpress.org/reference/functions/wp_get_attachment_image_src/

这可以解决问题:

 <?php wp_get_attachment_image_src('subgall-thumb'); ?>
 

请确保为要调用的缩略图使用正确的名称.

This does the trick:

<?php wp_get_attachment_image_src('subgall-thumb'); ?>

Make sure you use the correct name for the thumbnail that you are calling.

自WordPress 4.4起,有一个有效的核心功能可以比此处的答案更简洁地处理此问题.

您可以使用 the_post_thumbnail_url( $size ) 打印帖子缩略图的网址.

或者,如果要返回URL而不是立即输出URL,则可以使用 $url = get_the_post_thumbnail_url( $post_id, $size )

Since WordPress 4.4, there's an efficient core function that can handle this in a cleaner way than the answers here.

You can use the_post_thumbnail_url( $size ) which will print the URL of the post thumbnail.

Alternatively if you want to return the URL instead of immediately output it, you can use $url = get_the_post_thumbnail_url( $post_id, $size )

确定使用 simplexml_load_string

 $dom = simplexml_load_string(get_the_post_thumbnail());
$src = $dom->attributes()->src;
    echo $src;
 

Ok got it using simplexml_load_string

$dom = simplexml_load_string(get_the_post_thumbnail());
$src = $dom->attributes()->src;
    echo $src;

Another method are welcome.

请使用以下代码

 <?php get_the_post_thumbnail_url(); ?>
 

如果这还不足以实现您的目标,请尝试使用以下代码

 <?php $postimages = wp_get_attachment_image_src( get_post_thumbnail_id( get_the_ID() ), 'large' );

// Check for images if ( $postimages ) {

    // Get featured image   $postimage = $postimages[0];

} else {} while (have_posts() && $i < 8) : the_post(); echo esc_url( $postimage ); ?>
 

Please Use the below code

<?php get_the_post_thumbnail_url(); ?>

If It's not enough to achieve your goal then try below code

<?php $postimages = wp_get_attachment_image_src( get_post_thumbnail_id( get_the_ID() ), 'large' );

// Check for images if ( $postimages ) {

    // Get featured image   $postimage = $postimages[0];

} else {} while (have_posts() && $i < 8) : the_post(); echo esc_url( $postimage ); ?>

快速＆amp;肮脏的解决方案,将其拍在您主题的functions.php文件中

 FUNCTION GET_STRING_BETWEEN($STRING, $START, $END){
    $STRING = " ".$STRING;
    $INI = STRPOS($STRING, $START);
    IF ($INI == 0) RETURN "";
    $INI += STRLEN($START);
    $LEN = STRPOS($STRING, $END, $INI) - $INI;
    RETURN SUBSTR($STRING, $INI, $LEN);
}
 

在循环中使用,这将为您提供所需的内容

这将返回类似 http://foo.com/wp-content/uploads/2019/02/toy-story-two-was-ok.jpg

 $THE_FEATURED_IMAGE = GET_STRING_BETWEEN(get_the_post_thumbnail(NULL,'post-large'), 'src="', '" class="');
 

* "在循环中"=寻找类似while(have_posts()):the_post();

** 您还可以使用以下任何预定义的图像尺寸来替换" 后放大": 缩略图后, 后中 后满

For a quick & dirty solution, slap this in the functions.php file of your theme

FUNCTION GET_STRING_BETWEEN($STRING, $START, $END){
    $STRING = " ".$STRING;
    $INI = STRPOS($STRING, $START);
    IF ($INI == 0) RETURN "";
    $INI += STRLEN($START);
    $LEN = STRPOS($STRING, $END, $INI) - $INI;
    RETURN SUBSTR($STRING, $INI, $LEN);
}

Used within the loop, this will give you what you're looking for

This will return something like http://foo.com/wp-content/uploads/2019/02/toy-story-two-was-ok.jpg

$THE_FEATURED_IMAGE = GET_STRING_BETWEEN(get_the_post_thumbnail(NULL,'post-large'), 'src="', '" class="');

* "Within the loop" = look for something like while ( have_posts() ) : the_post();

**You can also sub out "post-large" with any of these predefined image sizes : post-thumbnail, post-medium, post-full
