Troubleshooting in WordPress can often seem like a daunting task. However, one feature that can assist with this endeavor is the wp_die function, which is particularly helpful for displaying error messages. Utilised correctly, this function can make the process of locating and identifying the root of your problems much more manageable. In this article, we will delve into the details of when, why and how to use the wp_die function for error messages, simplifying the debugging process for your WordPress site.
function wpturbo_custom_wp_die_error_message($message) {
wp_die( __( $message, 'wpturbo' ), __( 'An Error Occurred', 'wpturbo' ), array( 'response' => 403 ) );
}
wpturbo_custom_wp_die_error_message('Your custom error message here.');
This snippet starts by defining a new function named wpturbo_custom_wp_die_error_message($message). This function will be responsible for creating an error message that will halt script execution and display the provided message to the user.
function wpturbo_custom_wp_die_error_message($message) {
wp_die( __( $message, 'wpturbo' ), __( 'An Error Occurred', 'wpturbo' ), array( 'response' => 403 ) );
}When we invoke this function, it uses the wp_die() function. wp_die() is a WordPress function that is used to output a message and terminate script execution. This is typically used when an error is encountered. In our case, we’re using it to display our custom error message and halt any further script from running.
The wp_die() function takes three parameters. The first one is __( $message, 'wpturbo' ) which is the text message that will be displayed to the user. The __() function ensures this text is translatable to other languages in case your site or application supports multi-language.
The second parameter is __( 'An Error Occurred', 'wpturbo' ) which is the title of the error message page. This is also made translatable with the __() function.
The third parameter is array( 'response' => 403 ) and in this case, it represents the HTTP response code that will be sent back to the browser when the wp_die() function is executed. Here we’re specifying a 403 error code.
Lastly, we invoke or call our custom function to execute with `wpturbo_custom_wp_die_error_message(‘Your custom error message here.’);. Replace ‘Your custom error message here.’ with the error message you desire to display to your users in the event of a script execution error.
