Check if a file exists and return true/false or display a string containing information about the file.
This plugin provides the function
c2c_if_file_exists() (and a couple others) that check if a file exists and either returns true/false or displays a string containing information about the file.
If a format string is not passed to it, the functions return a simple boolean (true or false) indicating if the specified file exists.
Otherwise, the format string provided to it will be used to construct a response string, which can be customized to display information about the file (such as file_name, file_url, or file_path). If the
$echo argument is true, that string is displayed on the page. Regardless of the value of
$echo, the response string is returned by the function.
By default, 'c2c_if_file_exists()' assumes you are looking for the file relative to the default WordPress upload directory. If you wish to search another directory, specify it as the $dir argument. 'c2c_if_theme_file_exists()' assumes you are looking for a file relative to the currently active theme's home directory. 'c2c_if_plugin_file_exists()' assumes you are looking for a file relative to the directory that contains WordPress plugins.
