PHP 7.4 to PHP 8.1: Uncaught TypeError

  • Hello there,

    I upgraded my website from 7.4 to 8.1. Since then I’ve been getting this error message:

    Uncaught TypeError: count(): Argument #1 ($value) must be of type Countable|array, string given in […]

    This is the specified string:
    ‘count’ => count( $value ),

    $var = array(
    ‘html’ => $var . ‘Delete ‘,
    ‘count’ => count( $value ),
    ‘sortable’ => true,
    ‘limit’ => ”,
    ‘name’ => $this->parent->args[‘opt_name’] . ‘[‘ . $field[‘id’] . ‘][99999]’,
    );

    I don’t understand what’s wrong with that.

    Thanks in advance for your help,

    Jasmin

  • This is correct. Count will throw an error in above 8.0 but a warning in 7.4.33 as this “Warning: count(): Parameter must be an array or an object that implements Countable in /home/user/scripts/code.php on line 5
    1″

    I do not think it’s in WordPress but in a plugin or theme.

    You may try to inactivate plugins one by one or change theme to find the culprit.

    Thanks for your quick answer. I also think it’s a plugin issue caused by the theme. But I can’t update the theme or plugin because the theme is no longer supported. Do you have an idea how I can fix this anyway?

    What is meant by: … must be of type Countable|array … ?

    You can count elements of an array , but you can not count strings with count() function. It seems $value is a string.

    Either, the cause is a plugin or a theme. If you think is the theme, please change theme to a WP standard theme (as Twenty Twenty or Twenty Twenty Three) and look if the error dissappears!

    I do not know what theme you use, but if your theme is not maintained any more you have to select another one.

    If you know where the problem code is, you could patch the offending code. Examine the offending string value to decide what a proper count result should be. If the appropriate count is 1, conditionally (with is_string()) convert any string value into a single element array. If each string fragment should be counted, you could conditionally explode() the string into an array of string elements.

    TBH, switching to a better supported theme or plugin is the best option, but patching is possible for minor problems encountered during PHP updates.
