Examples
How to Display All Comment Statuses in WordPress
$statuses = get_comment_statuses();
foreach($statuses as $status => $label) {
echo "<p>Status: $status, Label: $label</p>";
}
In this code snippet, the get_comment_statuses() function is used to retrieve all comment statuses in WordPress. The function does not receive any parameters and returns an associative array of comment status labels keyed by status.
The foreach loop then iterates over each item in the array, and for each item, it outputs the status and label in a paragraph tag. The status and label are separated by a comma for clarity.
How to Check if a Specific Comment Status Exists
$statuses = get_comment_statuses();
if (array_key_exists('approved', $statuses)) {
echo "<p>The 'approved' comment status exists.</p>";
} else {
echo "<p>The 'approved' comment status does not exist.</p>";
}
In this example, the get_comment_statuses() function is used to retrieve all comment statuses. The array_key_exists() function is then used to check if the ‘approved’ comment status exists in the array of statuses.
If the ‘approved’ status exists, the message “The ‘approved’ comment status exists.” is displayed. If it does not exist, the message “The ‘approved’ comment status does not exist.” is displayed.
How to Count the Number of Comment Statuses
$statuses = get_comment_statuses();
echo "<p>There are ".count($statuses)." comment statuses.</p>";
In this example, the get_comment_statuses() function is used to retrieve all comment statuses. The count() function is then used to count the number of items in the array of statuses.
The number of comment statuses is then displayed in a paragraph tag.
