Change a function in file.php

Hi everybody!!

Maybe it’s a noobie question but i am trying to change the function called

function html( $field ) that is placed in \plugins\custom-field-suite\includes\fields\file.php. Because of size limitations, i have deleted some of the 250×250 images from uploads folder and the page is sending lots of 404 errors to server. I want to check if the image exists or not. Something like this…

function html( $field ) {
$file_url = $field->value;

if ( ctype_digit( $field->value ) ) {
if ( wp_attachment_is_image( $field->value ) ) {
$file_url = wp_get_attachment_image_src( $field->value );

$headers = get_headers($file_url[0], 1);
if (strpos($headers[‘Content-Type’], ‘image/’) !== false) {
$file_url = ‘‘;
} else {
$file_url = ”;
}

/*
$file_url = ‘‘;
*/
}
else
{
$file_url = wp_get_attachment_url( $field->value );
$filename = substr( $file_url, strrpos( $file_url, ‘/’ ) + 1 );
$file_url = ‘‘. $filename .’‘;
}
}

// CSS logic for “Add” / “Remove” buttons
$css = empty( $field->value ) ? array( ”, ‘ hidden’ ) : array( ‘ hidden’, ” );
?>
<span class=”file_url”><?php echo $file_url; ?></span>
<input type=”button” class=”media button add<?php echo $css[0]; ?>” value=”<?php _e( ‘Add File’, ‘cfs’ ); ?>” />
<input type=”button” class=”media button remove<?php echo $css[1]; ?>” value=”<?php _e( ‘Remove’, ‘cfs’ ); ?>” />
<input type=”hidden” name=”<?php echo $field->input_name; ?>” class=”file_value” value=”<?php echo $field->value; ?>” />
<?php
}

Unfortunedly this also sends 404 errors to server. Any idea of how to do it?

Other question …. Could i do it in my functions.php file of my child theme? I also try to put the entire php file under my child theme structure but is not working. Only change original file works for me.

Thanks in advance!!!!
