Check if a file exists and return true/false or display a string containing information about the file.

Scott Reilly

This plugin provides the functions <code>c2c_if_file_exists()</code>, <code>c2c_if_theme_file_exists()</code>, <code>c2c_if_plugin_file_exists()</code> that check if a file exists and either return true/false or display a string containing information about the file.
<ul>
<li>If a format string is not passed to it, the functions returns a simple boolean (true or false) indicating if the specified file exists.</li>
<li>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 directory, extension, name, path, size, or url). If the <code>$echo</code> argument is true, that string is displayed on the page. Regardless of the value of <code>$echo</code>, the response string is returned by the function.</li>
</ul>
By default, <code>c2c_if_file_exists()</code> 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 <code>$dir</code> argument. <code>c2c_if_theme_file_exists()</code> assumes you are looking for a file relative to the currently active theme’s home directory. <code>c2c_if_plugin_file_exists()</code> assumes you are looking for a file relative to the directory that contains WordPress plugins.

<h3>Developer Documentation</h3>
Developer documentation can be found in <a href="https://github.com/coffee2code/if-file-exists/blob/master/DEVELOPER-DOCS.md" rel="nofollow ugc">DEVELOPER-DOCS.md</a>. That documentation covers the template tags and hooks provided by the plugin.
As an overview, these are the template tags provided by the plugin:
<ul>
<li><code>c2c_if_file_exists()</code> : Checks if a file exists and returns true/false or displays a string containing information about the file.</li>
<li><code>c2c_if_plugin_file_exists()</code> : Checks if a file exists (relative to the plugins directory) and returns true/false or displays a string containing information about the file.</li>
<li><code>c2c_if_theme_file_exists()</code> : Checks if a file exists (relative to the current theme’s directory) and returns true/false or displays a string containing information about the file. If the current theme is a child theme, then the function will check if the file exists first in the child theme’s directory, and if not there, then it will check the parent theme’s directory.</li>
</ul>
These are the hooks provided by the plugin:
<ul>
<li><code>c2c_if_file_exists</code> : Filter that allows use of an alternative approach to safely invoke <code>c2c_if_file_exists()</code> in such a way that if the plugin were deactivated or deleted, then your calls to the function won’t cause errors in your site.</li>
<li><code>c2c_if_plugin_file_exists</code> : Filter that allows use of an alternative approach to safely invoke <code>c2c_if_plugin_file_exists()</code> in such a way that if the plugin were deactivated or deleted, then your calls to the function won’t cause errors in your site.</li>
<li><code>c2c_if_theme_file_exists</code> : Filter that allows use of an alternative approach to safely invoke <code>c2c_if_theme_file_exists()</code> in such a way that if the plugin were deactivated or deleted, then your calls to the function won’t cause errors in your site.</li>
</ul>
