IF statement inside a function to get value from an ACF field-CodePudding

I'm trying to create custom function in WordPress with ACF, and use it as a shortcode.

What I want to do is quite simple:

Get a field from ACF
Check if the text is "not found" or something else
If it's something else, I'll show an H2 and a sentence with field content.
If its "not found" I don't want to show anything

I tried various code, here's my last one:

// write a shortcode that creates a text if the field is not "not found"

function show_alliance() {
    $alliance = get_field('field_6383d4b46deed');

    if ($alliance !='not found'): {
        return '<h2>TITLE</h2><p>This is... '. $alliance .' </p>';
    }
    else: {
        return '';}
    }

add_shortcode('alliance', 'show_alliance')

By WordPress always comes up with errors when I save my snippet. I can't find a way to make it work.

(I use Code Snippets in WordPress)

Any ideas? (I'm sure it's very simple...)

Tried different syntax, but WordPress never validates the code snippet.

Last one is:

`L’extrait de code que vous essayez d’enregistrer a produit une erreur fatale à la ligne 11 :

syntax error, unexpected '}'`

When I delete the } to put it a the end it tells me that I should not have it there...

Please try this code I think this is working fine.

**PHP Code**

<?php if(get_field('field_6383d4b46deed')){ ?><h2>TITLE</h2><p>This is... '. $alliance .' </p>
else ?>
echo' ';
<?php } ?>

It looks like you have a syntax error in your code. The error message you provided suggests that you have an unexpected '}' character on line 11.

To fix this error, make sure that you have properly matched your curly braces '{' and '}'. In your code, you have an opening curly brace '{' after the if statement on line 5, but you are missing the closing curly brace '}' before the else statement on line 9.

You can fix this error by adding the missing closing curly brace '}' before the else statement, like this:

function show_alliance() {
$alliance = get_field('field_6383d4b46deed');
if ($alliance !='not found') {
    return '<h2>TITLE</h2><p>This is... '. $alliance .' </p>';
}
else {
    return '';
}

Here's the answer that works :

function show_alliance() {
    $alliance = get_field('field_6383d4b46deed');
    if ($alliance !='not found') {
        return '<h2>TITLE</h2><p>This is... '. $alliance .' </p>';
    }
    else {
        return '';
    }
}
add_shortcode('alliance', 'show_alliance');
