# Variables loaded from config files
|
|
|
|
Variables that are loaded from the [config files](../config-files.md) are
|
|
referenced by enclosing them within `#hash_marks#`, or with the smarty
|
|
variable [`$smarty.config`](language-variables-smarty.md#smartyconfig-languagevariablessmartyconfig). The
|
|
later syntax is useful for embedding into quoted attribute values, or
|
|
accessing variable values such as `$smarty.config.$foo`.
|
|
|
|
## Examples
|
|
|
|
Example config file - `foo.conf`:
|
|
```ini
|
|
pageTitle = "This is mine"
|
|
bodyBgColor = '#eeeeee'
|
|
tableBorderSize = 3
|
|
tableBgColor = "#bbbbbb"
|
|
rowBgColor = "#cccccc"
|
|
```
|
|
|
|
A template demonstrating the `#hash#` method:
|
|
|
|
```smarty
|
|
{config_load file='foo.conf'}
|
|
<html>
|
|
<title>{#pageTitle#}</title>
|
|
<body bgcolor="{#bodyBgColor#}">
|
|
<table border="{#tableBorderSize#}" bgcolor="{#tableBgColor#}">
|
|
<tr bgcolor="{#rowBgColor#}">
|
|
<td>First</td>
|
|
<td>Last</td>
|
|
<td>Address</td>
|
|
</tr>
|
|
</table>
|
|
</body>
|
|
</html>
|
|
```
|
|
|
|
A template demonstrating the
|
|
[`$smarty.config`](language-variables-smarty.md#smartyconfig-languagevariablessmartyconfig) method:
|
|
|
|
```smarty
|
|
{config_load file='foo.conf'}
|
|
<html>
|
|
<title>{$smarty.config.pageTitle}</title>
|
|
<body bgcolor="{$smarty.config.bodyBgColor}">
|
|
<table border="{$smarty.config.tableBorderSize}" bgcolor="{$smarty.config.tableBgColor}">
|
|
<tr bgcolor="{$smarty.config.rowBgColor}">
|
|
<td>First</td>
|
|
<td>Last</td>
|
|
<td>Address</td>
|
|
</tr>
|
|
</table>
|
|
</body>
|
|
</html>
|
|
```
|
|
|
|
Both examples would output:
|
|
|
|
```html
|
|
<html>
|
|
<title>This is mine</title>
|
|
<body bgcolor="#eeeeee">
|
|
<table border="3" bgcolor="#bbbbbb">
|
|
<tr bgcolor="#cccccc">
|
|
<td>First</td>
|
|
<td>Last</td>
|
|
<td>Address</td>
|
|
</tr>
|
|
</table>
|
|
</body>
|
|
</html>
|
|
```
|
|
|
|
Config file variables cannot be used until after they are loaded in from
|
|
a config file. This procedure is explained later in this document under
|
|
[`{config_load}`](../language-builtin-functions/language-function-config-load.md).
|
|
|
|
See also [variables](../language-basic-syntax/language-syntax-variables.md) and [$smarty reserved
|
|
variables](language-variables-smarty.md).
