这是我的第一篇文章,所以我将努力做到尽可能彻底。我也是PHP的新手。
这是一个使用PODS CMS插件的wordpress网站,因此请记住wordpress图像上传器允许访问一个单一图像上传的多种尺寸。这个概念是我有一组称为“团队”的数据,这个组有三个领域 - images,title,bio。我将为每个团队成员生成一个包含无序列表的缩略图列表,然后在另一个包含div的内容中,我将拥有更大版本的图像,标题和生物。我基本上是在制作一个标签式内容区域,其中缩略图是标签
最终的HTML输出将是:
<ul>
<li> <img src="thumbnailurl.jpg"/></li>
<li> <img src="thumbnailurl2.jpg"/></li>
<li> <img src="thumbnailurl3.jpg"/></li>
</ul>
<div class="panes">
<div><h2>Title 1</h2> <p> BIO CONTENT </p></div>
<div><h2>Title 1</h2> <p> BIO CONTENT </p></div>
<div><h2>Title 1</h2> <p> BIO CONTENT </p></div>
</div>
我当前遇到的问题是我可以获取第一条记录的所有图像网址,但是当涉及第二条foreach中的第二条记录时,我需要为新记录重新运行数组但是我无法弄清楚如何。
<?php
$Record = new Pod('the_team');
$Record->findRecords($orderby = 't.id DESC');
$mylist=array();
while ($Record->fetchRecord())
{
$image_array = $Record->get_field('photo');
$title = $Record->get_field('name');
$desc = $Record->get_field('bio');
$id = $Record->get_field('id');
$mylist[] = array('name' => $title, 'desc' => $desc, 'id'=> $id );
?>
<ul>
<?php
foreach($image_array as $i => $image)
{
$image_thumb_url = wp_get_attachment_image_src( $image['ID'], 'thumbnail', false );
$image_thumb_url = $image_thumb_url[0];
$image_med_url = wp_get_attachment_image_src( $image['ID'], 'medium', false );
$image_med_url = $image_med_url[0];
$image_large_url = wp_get_attachment_image_src( $image['ID'], 'large', false );
$image_large_url = $image_large_url[0];
$image_full_url = wp_get_attachment_image_src( $image['ID'], 'full', false );
$image_full_url = $image_full_url[0];
?>
<li>
<a href="<?php echo $image_large_url; ?>">
<img src="<?php echo $image_thumb_url; ?>" />
</a>
</li>
<?php } ?>
<?php } ?>
</ul>
<div class="panes">
<?php
foreach ($mylist as $person)
{ ?>
<div class="team-member" id="member<?php echo $person['id']; ?>">
<h2><?php echo $person['name']; ?></h2>
<?php echo $person['desc']; ?>
<a href="<?php echo $person['photo']; ?>">
<img src="<?php echo $person['photo']; ?>" />
</a>
<?php } ?>
</div>
</div>
Okkkay ..所以我解决了第一个问题!但它带来了第二个。我想我将需要第二个图像字段或只调用<li>
中数组中的第一个图像,而只调用<div>
数组中的第二个图像:
<?php
$Record = new Pod('the_team');
$Record->findRecords($orderby = 't.id DESC');
$mylist=array();
$cnt = 0;
?>
<ul class="tabs">
<?php
while ($Record->fetchRecord()) :
$mylist[$cnt] = array(
'name' => $Record->get_field('name'),
'desc' => $Record->get_field('bio'),
'id'=> $Record->get_field('id')
);
?>
<?php
$image_array = $Record->get_field('photo');
foreach($image_array as $i => $image) :
$image_thumb_url = wp_get_attachment_image_src( $image['ID'], 'thumbnail', false );
$mylist[$cnt]['img_thumb'] = $image_thumb_url[0];
$image_med_url = wp_get_attachment_image_src( $image['ID'], 'medium', false );
$mylist[$cnt]['img_med'] = $image_med_url[0];
$image_large_url = wp_get_attachment_image_src( $image['ID'], 'large', false );
$mylist[$cnt]['img_large'] = $image_large_url[0];
$image_full_url = wp_get_attachment_image_src( $image['ID'], 'full', false );
$mylist[$cnt]['img_full'] = $image_full_url[0];
?>
<li>
<a href="#">
<img src="<?php echo $image_thumb_url[0]; ?>" />
</a>
</li>
<?php endforeach; ?>
<?php
$cnt++;
endwhile;
?> </ul>
<div class="panes">
<?php foreach ($mylist as $person) : ?>
<div class="team-member" id="member<?php echo $person['id']; ?>"><div id="member-info"><h2>Meet <?php echo $person['name']; ?></h2>
<?php echo $person['desc']; ?></div>
<a href="<?php echo $person['img_large']; ?>" rel="prettyPhoto">
<img src="<?php echo $person['img_med']; ?>" style="float:left" />
</a>
</div>
<?php endforeach; ?>
</div>
答案 0 :(得分:0)
我想我能看出你的问题是什么。您的第二个foreach
循环不会从while
循环中受益,因此,如果遵循此路径,则唯一的选择是重新循环获取的数据。我不建议这样做,因为几乎总有一种方法可以将第二个循环所需的代码写入原始循环。
作为一个例子,我重写了你的代码,将第二个foreach
循环合并到while循环中(否定它的需要)。这样,每条记录都有$html
和$html2
的新条目。一旦它循环通过你有两个变量,你可以连接生成你正在寻找的完整的HTML。
<?php
$Record = new Pod('the_team');
$Record->findRecords($orderby = 't.id DESC');
// Custom variables
$html = "<ul>\n";
$html2 = "";
$image_type=array('thumbnail','medium','large','full');
while ($Record->fetchRecord()) {
$image_array = $Record->get_field('photo');
$title = $Record->get_field('name');
$desc = $Record->get_field('bio');
$id = $Record->get_field('id');
foreach($image_array as $i => $image) {
foreach ($image_type as $type) {
$image_temp = wp_get_attachment_image_src( $image['ID'], $type , false );
$image_url[$type] = $image_temp[0];
} # End of Foreach loop
// Create List HTML in primary output variable
$html .= "<li>\n".
"<a href=\"" . $image_url['large'] ."\">\n".
"<img src=\"" . $image_url['thumbnail'] ."\" />\n".
"</a>\n".
"</li>\n";
} #End of foreach loop
// Create User HTML in secondary output variable
$html2 .= "\t<div class=\"team-member\" id=\"member" . $id . ">\n".
"<h2>" . $title . "</h2>\n".
$desc . "\n".
"<a href=\"" . $photo . ">\n". # $photo is not declared in this code (will error)
"<img src=\"" . $photo . " />\n". # as above comment
"</a>\n";
"</div>\n";
} # End of while loop
// Wrap up the list elements, concat the secondary HTML.
$html .= "</ul>\n\n".
"<div class=\"panes\">\n".
$html2 . "\n".
"</div>\n";
echo $html;
?>
