    Hello,
    I put this simple code in a snippet.
    I get an error that blocks the whole site. I can’t log in to the dashboard.
    I need to log into the database and disable the database snippet.
    Where is it wrong?

    / The Query

    $args = array(
	'post_type' => 'post',
);
$the_query = new WP_Query( $args );
 
// The Loop
if ( $the_query->have_posts() ) {
    echo '<ul>';
    while ( $the_query->have_posts() ) {
        $the_query->the_post();
        echo '<li>' . get_the_title() . '</li>';
    }
    echo '</ul>';
} else {
    echo '<h1>no posts found</h1>';
}
/* Restore original Post Data */
wp_reset_postdata();

    Log:

    I put this simple code in a snippet.

    Where? Which file?

    I recommend asking for help through the code-snippets plugin’s dedicated support channel. It’s trying to eval your snippet. Using eval isn’t always 100% reliable.

    Alternatives to eval is to place your code on a template file, or execute it from an action hook, or convert it into a shortcode or custom block.

    Hello,

    For me this code (unmodified) worked well when wrapped into a function with a shortcode and placed either in functions.php or using the plugins “my-custom-functions” or “code-snippets”.

    Hello
    I inserted the code using the Code Snippets plugin. the site crashes.
    I created a child theme of Astra and placed the code in the function.php file. It works!
    The problem is that the query affects all pages on the site including the back office. Is there any way to query for a single page only?

    Sure! Depending on whether you have the post’s ID or slug, add one or the other to the $args array (substituting valid values of course):
    'p' => 12345,
    or
    'name' => 'foobar',

    ‘name’ => ‘home’,

    in this way the query will be executed only on the “home” page. is it correct?

    Not quite. Assuming you’ve selected “static” home page in WP settings and chose a page named “home” to serve as your home page, then use pagename' => 'home',. “name” is for single post names.
