11 * |
|
12 * The metadata of the plugin's data searches for the following in the plugin's |
|
13 * header. All plugin data must be on its own line. For plugin description, it |
|
14 * must not have any newlines or only parts of the description will be displayed |
|
15 * and the same goes for the plugin data. The below is formatted for printing. |
|
16 * |
|
17 * <code> |
|
18 * /* |
|
19 * Plugin Name: Name of Plugin |
|
20 * Plugin URI: Link to plugin information |
|
21 * Description: Plugin Description |
|
22 * Author: Plugin author's name |
|
23 * Author URI: Link to the author's web site |
|
24 * Version: Must be set in the plugin for WordPress 2.3+ |
|
25 * Text Domain: Optional. Unique identifier, should be same as the one used in |
|
26 * plugin_text_domain() |
|
27 * Domain Path: Optional. Only useful if the translations are located in a |
|
28 * folder above the plugin's base path. For example, if .mo files are |
|
29 * located in the locale folder then Domain Path will be "/locale/" and |
|
30 * must have the first slash. Defaults to the base folder the plugin is |
|
31 * located in. |
|
32 * * / # Remove the space to close comment |
|
33 * </code> |
|
34 * |
|
35 * Plugin data returned array contains the following: |
|
36 * 'Name' - Name of the plugin, must be unique. |
|
37 * 'Title' - Title of the plugin and the link to the plugin's web site. |
|
38 * 'Description' - Description of what the plugin does and/or notes |
|
39 * from the author. |
|
40 * 'Author' - The author's name |
|
41 * 'AuthorURI' - The authors web site address. |
|
42 * 'Version' - The plugin version number. |
|
43 * 'PluginURI' - Plugin web site address. |
|
44 * 'TextDomain' - Plugin's text domain for localization. |
|
45 * 'DomainPath' - Plugin's relative directory path to .mo files. |
|
46 * |
|
47 * Some users have issues with opening large files and manipulating the contents |
|
48 * for want is usually the first 1kiB or 2kiB. This function stops pulling in |
|
49 * the plugin contents when it has all of the required plugin data. |
|
50 * |
|
51 * The first 8kiB of the file will be pulled in and if the plugin data is not |
|
52 * within that first 8kiB, then the plugin author should correct their plugin |
|
53 * and move the plugin data headers to the top. |
|
54 * |
|
55 * The plugin file is assumed to have permissions to allow for scripts to read |
|
56 * the file. This is not checked however and the file is only opened for |
|
57 * reading. |
