PHP of custom field inside PHP Tag

Question

I´m display a slider that get´s the images from custom field, now I need that the slider shows different images depending on the language (es - ca):

This is the code of the slider:

        <a href="<?php the_field('slider_home_1_enlace') ?>">
            <img src="<?php the_field('slider_home_1'); ?>">
        </a>

So I´m creating a conditional tag to load images depending of the language of qtranslate plugin:

        <?php
        _e('<!--:es-->
                <a href="<?php the_field('slider_home_1_enlace') ?>">
                    <img src="<?php <the_field('slider_home_1'); ?>">
                </a>
            <!--:-->
            <!--:ca-->
                <a href="<?php the_field('slider_home_1_enlace_ca') ?>">
                    <img src="<?php the_field('slider_home_1_ca'); ?>">
                </a>
            <!--:-->');
        ?>

I´m a php begginer so I see the problem maybe that the php is inside another php, because this way its not working, if i just put text between tags it works properly for the language.

Any ideas how to syntax this?

you should complete each php tag.before writing new php tag lik <?php code here ?> — bounty_killer525

You need to check language first, using if - else

detect the language and store it to the variable named $language and then check the condition as below.

<?php
if(qtrans_getLanguage()=="es"){
?>
  <a href="<?php the_field('slider_home_1_enlace'); ?>">
      <img src="<?php the_field('slider_home_1'); ?>">
  </a>
<?php
} else if(qtrans_getLanguage()=="ca"){
?>
  <a href="<?php the_field('slider_home_1_enlace_ca'); ?>">
      <img src="<?php the_field('slider_home_1_ca'); ?>">
  </a>
<?php
}
?>

@diego how you are detecting the language selected? I mean how would u know which language to show?

codek Over a year ago

i'm just using qtranslate and with this it detects the language "" i'm not using anymore

Pankit Kapadia Over a year ago

if you are using qtranslate then check the if condition like this if(qtrans_getLanguage()=='en')

You can't have php-tags inside each other.

Use basic string concatenation to combine your strings: http://php.net/manual/en/language.operators.string.php

You can't use it that way. Compare: (I guess that the_field() returns the string ;))

<a href="'.the_field("slider_home_1_enlace").'">
    <img src="'.the_field("slider_home_1").'" />
</a>

There are multiple mistakes. At first, you can't use the

'.(your things here).'

Second, theres a < in your fourth line and you forget to close your img-tag.

this doesn´t gives error, but the problem is that it shows the url of the image instead of displaying it :S do you know why?

looper Over a year ago

Are you sure that the path is correct? Most browsers display the path, if the image doesn't exist. Note: I had a typo in my code. Try again.

looper Over a year ago

Hm. The img-tag is correct; if the path is too, I don't know. Please check the resulting html!

codek Over a year ago

the resulting html is that it displays the full text plain of the "a" and the "img", not with the tags

First, install the qTranslate Wordpress plugin.

Then, you can try this:

<?php

    $slider_img_fields_langs = array(
        '',
        'ca',
        'es',
    );

    $lang = qtrans_getLanguage();
    if( !in_array( $lang, $slider_img_fields_langs ) );
        $lang = '';

    echo '
<a href="' . the_field( 'slider_home_1_enlace' . $lang ) . '">
    <img src="' . the_field( 'slider_home_1' . $lang ) . '">
</a>';

?>
