 array(4) { [109]=> array(11) { ["ID"]=> string(3) "109" ["name"]=> string(29) "unsplash_52cd96f512830_1.jpeg" ["path"]=> string(113) "/Users/framecero/Framecero_Clientes/MIMO/MAMP/fashionist/wp-content/uploads/2014/03/unsplash_52cd96f512830_1.jpeg" ["url"]=> string(97) "http://localhost:8888/fashionist/wp-content/uploads/2014/03/unsplash_52cd96f512830_1-150x150.jpeg" ["width"]=> int(150) ["height"]=> int(150) ["full_url"]=> string(89) "http://localhost:8888/fashionist/wp-content/uploads/2014/03/unsplash_52cd96f512830_1.jpeg" ["title"]=> string(24) "unsplash_52cd96f512830_1" ["caption"]=> string(0) "" ["description"]=> string(0) "" ["alt"]=> string(0) "" } [113]=> array(11) { ["ID"]=> string(3) "113" ["name"]=> string(29) "unsplash_52d65d1ebeeb2_1.jpeg" ["path"]=> string(113) "/Users/framecero/Framecero_Clientes/MIMO/MAMP/fashionist/wp-content/uploads/2014/03/unsplash_52d65d1ebeeb2_1.jpeg" ["url"]=> string(97) "http://localhost:8888/fashionist/wp-content/uploads/2014/03/unsplash_52d65d1ebeeb2_1-150x150.jpeg" ["width"]=> int(150) ["height"]=> int(150) ["full_url"]=> string(89) "http://localhost:8888/fashionist/wp-content/uploads/2014/03/unsplash_52d65d1ebeeb2_1.jpeg" ["title"]=> string(24) "unsplash_52d65d1ebeeb2_1" ["caption"]=> string(0) "" ["description"]=> string(0) "" ["alt"]=> string(0) "" } [132]=> array(11) { ["ID"]=> string(3) "132" ["name"]=> string(29) "unsplash_523ae1f5502d6_1.jpeg" ["path"]=> string(113) "/Users/framecero/Framecero_Clientes/MIMO/MAMP/fashionist/wp-content/uploads/2014/03/unsplash_523ae1f5502d6_1.jpeg" ["url"]=> string(97) "http://localhost:8888/fashionist/wp-content/uploads/2014/03/unsplash_523ae1f5502d6_1-150x150.jpeg" ["width"]=> int(150) ["height"]=> int(150) ["full_url"]=> string(89) "http://localhost:8888/fashionist/wp-content/uploads/2014/03/unsplash_523ae1f5502d6_1.jpeg" ["title"]=> string(24) "unsplash_523ae1f5502d6_1" ["caption"]=> string(0) "" ["description"]=> string(0) "" ["alt"]=> string(0) "" } [163]=> array(11) { ["ID"]=> string(3) "163" ["name"]=> string(12) "building.jpg" ["path"]=> string(96) "/Users/framecero/Framecero_Clientes/MIMO/MAMP/fashionist/wp-content/uploads/2014/03/building.jpg" ["url"]=> string(80) "http://localhost:8888/fashionist/wp-content/uploads/2014/03/building-150x150.jpg" ["width"]=> int(150) ["height"]=> int(150) ["full_url"]=> string(72) "http://localhost:8888/fashionist/wp-content/uploads/2014/03/building.jpg" ["title"]=> string(8) "building" ["caption"]=> string(0) "" ["description"]=> string(0) "" ["alt"]=> string(0) "" } }

我需要在 foreach 中获取 url，我正在使用此代码：

<?php global $post;$medias = rwmb_meta( 'mimo_imgadv', 'type=image_advanced' );?>
<?php  } else {$medias = '';}; ?>
<?php if ($medias !== ''){ ?>
<div  class="cn_wrapper flexslider" >
    <ul id="allimg_id<?php the_Id(); ?>" class="format_images slides">
        <?php foreach($medias as $media){

        // check if string ends with image extension
            if (preg_match('/(\.jpg|\.png|\.bmp)$/', $media['url'])) {
                echo '<li class="selector">';
                ?>
                <a class="mimo-link-overimage" href="<?php the_permalink(); ?> " >
                         <div class="mimo-image-hover"><i class="fa fa-file-o"></i></div> 

                <?php
                echo '<img src="' . $media['url']  . '" alt=""/>';
                echo '</a>';
                echo '</li>';
            // check if there is youtube.com in string
            }           
        }       

        ?>
    </ul>
</div>

但它只给了我最后一个网址。

有人知道代码发生了什么吗？

【问题讨论】：

我实际看到的唯一网址以"jpeg" 结尾，这与您的正则表达式完全不匹配。
嗨，我终于解决了，问题是上面的代码正在运行:)
我也是你推荐的 'jpeg' 但没有它也能正常工作？¿?

标签： php arrays foreach

【解决方案1】：

您只需要编辑您的正则表达式来检测您阵列中的文件类型。您正在寻找 .jpg、.png 和 .bmp 类型，但这些类型的数组中只有一个文件。这就是为什么你只得到一个结果。其他三个图像是 .jpeg。这是包含其他文件的编辑代码：

<?php foreach($medias as $media){
    // check if string ends with image extension
    if (preg_match('/(\.jpg|\.jpeg|\.png|\.bmp)$/', $media['url'])) {
        echo '<li class="selector">';
        //remaining code unchanged...
?>
