在PHP循环- WordPress自定义字段中添加If/Else语句

Question

我有这个WordPress自定义字段PHP循环：

<?php
    $fields = CFS()->get('image-field');
    foreach ($fields as $field) {
?>

    <a href="<?php echo $field['image-upload']; ?>">Link to image</a>
    <a href="<?php echo $field['image-url']; ?>">Link to image</a>
    <?php echo $field['image-description']; ?>

<?php } ?>

并希望添加If/ And语句，例如(这不起作用)：

<?php
    $fields = CFS()->get('image-field');
    foreach ($fields as $field) {
?>

    if ( $field['image-upload'] ) {
        <a href="<?php echo $field['image-upload']; ?>">Link to image</a>
    }
    else {
        <a href="<?php echo $field['image-url']; ?>">Link to image</a>
    }
    <?php echo $field['image-description']; ?>

<?php } ?>

我发现这很管用

<?php
    $fields = CFS()->get('image-field');
    foreach ($fields as $field) {
        if ( $field['image-upload'] ) {
        ?>
            <a href="<?php echo $field['image-upload']; ?>">Go To Store!</a>
        <?php
        } else {
            echo $field['image-url'];
        }
        echo $field['image-description'];
        }
?>

但是，在尝试添加HTML时，我在上面的代码中遇到了语法错误。

编辑:工作解决方案，谢谢水晶

    <?php
    $fields = CFS()->get('image-field');
    ?>

    <? foreach ($fields as $field) : ?>
    <ul>
        <? if ( $field['image-upload'] ) : ?>
            <li><a href="<?= $field['image-upload'] ?>">Link to image</a>
        <? else : ?>
            <li><a href="<?= $field['image-url'] ?>">Link to image</a>
        <? endif ?>
            <li><?= $field['image-description'] ?>
    </ul>
    <? endforeach ?>

Answer 1

HTML应该用echo或<?php ... ?>外部编写，如下所示：

<?php
$fields = CFS()->get('image-field');
foreach ($fields as $field) {

    if ( $field['image-upload'] ) { ?>
        <a href="<?php echo $field['image-upload']; ?>">Link to image</a>
    <?php } else { ?>
        <a href="<?php echo $field['image-url']; ?>">Link to image</a>
    <?php
    }
    echo $field['image-description'];
}
?>

如果使用short_open_tag：

<?php
$fields = CFS()->get('image-field');
?>

<? foreach ($fields as $field) : ?>
    <? if ( $field['image-upload'] ) : ?>
        <a href="<?= $field['image-upload'] ?>">Link to image</a>
    <? else : ?>
        <a href="<?= $field['image-url'] ?>">Link to image</a>
    <? endif ?>
    <?= $field['image-description'] ?>
<? endforeach ?>
