Question

早上好，我正在为客户建立一个网站，我正在使用Wordpress进行CMS，我的PHP知识非常有限。我正在使用自定义字段插件，我正在尝试在模板中添加if语句以显示元数据，如果字段在CMS中填写，这是我目前所拥有的，但它仍然显示即使没有填写元字段，也可以使用该按钮。

<?php if(get_field('owners_manual')) ?>
<?php {  ?>
    <a href="<?php the_field('owners_manual'); ?>" class="pdf-button" target=_"blank">Owners Manual</a>
<?php }  ?>

<?php if(get_field('parts_booklet')) ?>
<?php {  ?>
    <a href="<?php the_field('parts_booklet'); ?>" class="parts-button" target=_"blank">Parts Booklet</a>
<?php }  ?>

<?php if(get_field('sales_leaflet')) ?>
<?php {  ?>
    <a href="<?php the_field('sales_leaflet'); ?>" class="leaflet-button" target=_"blank">Sales Leaflet</a>
<?php }  ?>

Answer 1

试试这个

<?php if(get_field('owners_manual') != "") ?>
<?php {  ?>
    <a href="<?php the_field('owners_manual'); ?>" class="pdf-button" target=_"blank">Owners Manual</a>
<?php }  ?>

<?php if(get_field('parts_booklet') != "") ?>
<?php {  ?>
    <a href="<?php the_field('parts_booklet'); ?>" class="parts-button" target=_"blank">Parts Booklet</a>
<?php }  ?>

<?php if(get_field('sales_leaflet') != "") ?>
<?php {  ?>
    <a href="<?php the_field('sales_leaflet'); ?>" class="leaflet-button" target=_"blank">Sales Leaflet</a>
<?php }  ?>

解决

                        <!-- Owners Manual -->
                        <?php
                            if( get_field('owners_manual') ):
                            $owners_link = get_field('owners_manual');
                        ?>
                        <a href="<?php echo $owners_link ?>" class="pdf-button" target=_"blank">Owners Manual</a>
                        <?php endif; ?>

                        <!-- Parts Booklet -->
                        <?php
                            if( get_field('parts_booklet') ):
                            $parts_link = get_field('parts_booklet');
                        ?>
                        <a href="<?php echo $parts_link ?>" class="parts-button" target=_"blank">Parts Booklet</a>
                        <?php endif; ?>

                        <!-- Sales leaflet -->
                        <?php
                            if( get_field('sales_leaflet') ):
                            $sales_link = get_field('sales_leaflet');
                        ?>
                        <a href="<?php echo $sales_link ?>" class="leaflet-button" target=_"blank">Sales Leaflet</a>
                        <?php endif; ?>
