高级自定义字段语法错误

Question

I am editing a wordpress theme to add two fields to a slider plugin. I am using advanced custom fields to do this since I don't know PHP too well.

added customheader-img and big-descrip

 $videobg_container .= ' <li> <div class="slide-container container text-'.$videobg_alignment.'"> <div class="slide-content page-scroll" style="vertical-align:'.$videobg_vertical_alignment.';"> <div class="customheader-img">$image = get_field('.$custom_header_image.');</div> '.$videobg_description.$videobg_title.$button1.' <div class="big-descrip" <?php the_field( 'Subtext'); ?></div> </div> </div> </li>'; } 

The code above spits out a syntax error. If I change the single quotes to double quotes ('Subtext') to ("Subtext") it doesn't error out but the content I add to the custom field doesn't show up.

Any ideas what I can do here?

Thanks!

Answer 1

Try this:

$videobg_container .='   
<li>
  <div class="slide-container container text-' . $videobg_alignment . '">
     <div class="slide-content page-scroll" style="vertical-align:' . $videobg_vertical_alignment . '">
         <div class="customheader-img">' . get_field('custom_header_image')['url'] .'</div>
       '.$videobg_description.$videobg_title.$button1.'
        <div class="big-descrip">'. get_field('Subtext'). '"></div>                     
    </div>
  </div>
</li>';

For more info how to query a image ACF field you could read in ACF docs

Answer 2

To get Image field using ACF

$image = get_field('image');

Use print_r($image); and see to that there are multiple dimensions of the image uploaded and you could display based on the key values of the array // each image contains a custom field called 'link'

$link = get_field('link', $image['ID']);

At last you can have the image as <?php echo $image['url']; ?> <?php echo $image['url']; ?>

To get the text or some other contents from ACF

$variable = get_field('field_name');

Another Important thing is that you have to use render of the variable to print the image that you have obtained Usage of print_r() will lead us to display the image as per our resolutions.
