A sub-template is what the HTML is in. For example, admins can change the admin_login sub-template to make the administrative password prompt look different. They could change the error sub-template to change what is displayed upon an error.
It's important to note that sub-templates are grouped within templates. The error sub-template "template_fatal_error()" can be found in the Errors.template.php, just as shown below.
// Show an error message...
function template_fatal_error()
{
global $context, $settings, $options, $txt;
echo '
<table border="0" width="80%" cellspacing="0" align="center"
cellpadding="4" class="tborder">
<tr class="titlebg">
<td>', $context['error_title'], '</td>
</tr>
<tr class="windowbg">
<td style="padding-top: 3ex; padding-bottom: 3ex;">
', $context['error_message'], '
</td>
</tr>
</table>';
// Show a back button (using javascript.)
echo '
<div align="center" style="margin-top: 2ex;">
<a href="javascript:history.go(-1)">', $txt[250], '</a>
</div>';
}
Breaking it down:
Code:
// Show an error message...
This is used for comments to guide and tell the admin what the following block of code is.
Code:
function template_fatal_error()
{
}
In JavaScript, this is the sub-template that will be executed upon encountering an error.
Code:
global $context, $settings, $options, $txt;
This is a PHP declaration of some variables.
Code:
echo '
<table border="0" width="80%" cellspacing="0" align="center"
cellpadding="4" class="tborder">
<tr class="titlebg">
<td>', $context['error_title'], '</td>
</tr>
<tr class="windowbg">
<td style="padding-top: 3ex; padding-bottom: 3ex;">
', $context['error_message'], '
</td>
</tr>
</table>';
This is the actual HTML that will be sent to the browser. Note the use of the previously declared variable, $context.
Code:
// Show a back button (using JavaScript.)
This is another comment.
Code:
echo ' <div align="center" style="margin-top: 2ex;"> <a href="javascript:history.go(-1)">', $txt[250], '</a> </div>';
This is some more HTML code that will be sent to the browser.
