config.tpl (required)
|
|
\layout Standard
|
|
|
|
In your application/templates/default directory, create a new template file
|
|
named 'config.tpl'.
|
|
This will be included by config.php and used to draw the page.
|
|
This template should include a POST method form.
|
|
The following template tags may be used:
|
|
\layout Enumerate
|
|
|
|
{action_url} - A egw->link to config.php will be inserted.
|
|
\layout Enumerate
|
|
|
|
{title} - This will be parsed to display 'Site Configuration'.
|
|
\layout Enumerate
|
|
|
|
{th_bg},{th_text},{row_on},{row_off} - Replaced with the current theme colors.
|
|
\layout Standard
|
|
|
|
and the following special types:
|
|
\layout Enumerate
|
|
|
|
{lang_XXX} - Filled with lang('XXX').
|
|
\layout Enumerate
|
|
|
|
{value_XXX} - Filled with the current value of config item 'XXX'.
|
|
\layout Enumerate
|
|
|
|
{selected_XXX} - set to '', or ' selected' if an option value is current.
|
|
\layout Enumerate
|
|
|
|
{hook_XXX} - Calls a function named XXX (will be discussed later).
|
|
\layout Standard
|
|
|
|
Following is an example from the addressbook application:
|
|
\layout Code
|
|
|
|
<form method="POST" action="{action_url}">
|
|
\layout Code
|
|
|
|
<table border="0" align="center">
|
|
\layout Code
|
|
|
|
<tr bgcolor="{th_bg}">
|
|
\layout Code
|
|
|
|
<td colspan="2"><font color="{th_text}"> <b>{title}</b></font></td>
|
|
\layout Code
|
|
|
|
</tr> <tr bgcolor="{th_err}">
|
|
\layout Code
|
|
|
|
<td colspan="2"> <b>{error}</b></font></td>
|
|
\layout Code
|
|
|
|
</tr>
|
|
\layout Code
|
|
|
|
<!-- END header -->
|
|
\layout Code
|
|
|
|
<!-- BEGIN body -->
|
|
\layout Code
|
|
|
|
<tr bgcolor="{row_on}">
|
|
\layout Code
|
|
|
|
<td colspan="2"> </td>
|
|
\layout Code
|
|
|
|
</tr>
|
|
\layout Code
|
|
|
|
<tr bgcolor="{row_off}">
|
|
\layout Code
|
|
|
|
<td colspan="2"> <b>{lang_Addressbook}/{lang_Contact_Settings}</b></font>
|
|
\layout Code
|
|
|
|
</td>
|
|
\layout Code
|
|
|
|
</tr>
|
|
\layout Code
|
|
|
|
<tr bgcolor="{row_on}">
|
|
\layout Code
|
|
|
|
<td>{lang_Contact_application}:</td>
|
|
\layout Code
|
|
|
|
<td><input name="newsettings[contact_application]" value="{value_contact_appli
|
|
cation}"></td>
|
|
\layout Code
|
|
|
|
</tr>
|
|
\layout Code
|
|
|
|
...
|
|
\layout Standard
|
|
|
|
Note the fieldname, newsettings[contact_application].
|
|
This array name must be used for the form values.
|
|
Next, note the value setting for this form element, {value_contact_application}.
|
|
This indicates that we want the current value of the config setting, 'contact_a
|
|
pplication', to be set and displayed on the form.
|
|
Lastly, look at the template element, {lang_Contact_application}.
|
|
Here, the value from the lang db table will be inserted if available.
|
|
\layout Standard
|
|
|
|
Let's take a look at part of the preferences/default/config.tpl:
|
|
\layout Code
|
|
|
|
<tr bgcolor="{row_on}">
|
|
\layout Code
|
|
|
|
<td>{lang_Country_Selection} ({lang_Text_Entry}/{lang_SelectBox}):</td>
|
|
\layout Code
|
|
|
|
<td>
|
|
\layout Code
|
|
|
|
<select name="newsettings[countrylist]">
|
|
\layout Code
|
|
|
|
{hook_country_set}
|
|
\layout Code
|
|
|
|
</select>
|
|
\layout Code
|
|
|
|
</td>
|
|
\layout Code
|
|
|
|
</tr>
|
|
\layout Standard
|
|
|
|
Here, we are adding a new element, {hook_country_set}.
|
|
This brings up the next file we will need to parse this value...
|
|
\layout Subsection
|
|
|
|
hook_config.inc.php (optional)
|
|
\layout Standard
|
|
|
|
At each invocation of config.php, a call to the common class function hook_single
|
|
() is made.
|
|
It attempts to include a file, hook_config.inc.php as a set of code for config.php
|
|
to use.
|
|
In the case of the preferences example above, using hook_country_set, here
|
|
is the corresponding function in preferences/inc/hook_config.inc.php:
|
|
\layout Code
|
|
|
|
function country_set($config)
|
|
\layout Code
|
|
|
|
{
|
|
\layout Code
|
|
|
|
$country = array( 'user_choice' => 'Users Choice', 'force_select' =>
|
|
'Force Selectbox' );
|
|
\layout Code
|
|
|
|
while (list ($key, $value) = each ($country))
|
|
\layout Code
|
|
|
|
{
|
|
\layout Code
|
|
|
|
if ($config['countrylist'] == $key)
|
|
\layout Code
|
|
|
|
{
|
|
\layout Code
|
|
|
|
$selected = ' selected';
|
|
\layout Code
|
|
|
|
}
|
|
\layout Code
|
|
|
|
else
|
|
\layout Code
|
|
|
|
{
|
|
\layout Code
|
|
|
|
$selected = '';
|
|
\layout Code
|
|
|
|
}
|
|
\layout Code
|
|
|
|
$descr = lang($value);
|
|
\layout Code
|
|
|
|
$out .= '<option value="' .
|
|
$key .
|
|
'"' .
|
|
$selected .
|
|
'>' .
|
|
$descr .
|
|
'</option>' .
|
|
"
|
|
\backslash
|
|
n";
|
|
\layout Code
|
|
|
|
}
|
|
\layout Code
|
|
|
|
return $out;
|
|
\layout Code
|
|
|
|
}
|
|
\layout Standard
|
|
|
|
Note again the template value we used earlier, {hook_country_set}.
|
|
This causes config.php to look for a function named country_set().
|
|
Since we included the file with this function via the hook_single() call,
|
|
this function is executed.
|
|
It's return is a string, and the function prints nothing itself.
|
|
\layout Subsection
|
|
|
|
hook_config_validate.inc.php (optional)
|
|
\layout Standard
|
|
|
|
Once the admin clicks the submit button to post the form, we can optionally
|
|
validate their input using one or many different functions.
|
|
This is done by first making another call to hook_single() in the API common
|
|
class.
|
|
This time, the name config_validate is used, so common tries to include
|
|
'application/inc/hook_config_validate.inc.php'.
|
|
\layout Standard
|
|
|
|
If this file exists, it sets a var to tell config.php it was found.
|
|
Following then are functions named after each config we want to validate.
|
|
The following example is for addressbook:
|
|
\layout Code
|
|
|
|
$GLOBALS['phpgw_info']['server']['found_validation_hook'] = True;
|
|
\layout Code
|
|
|
|
\layout Code
|
|
|
|
/* Check a specific setting.
|
|
Name must match the setting.
|
|
*/
|
|
\layout Code
|
|
|
|
function ldap_contact_context($value='')
|
|
\layout Code
|
|
|
|
{
|
|
\layout Code
|
|
|
|
if($value == $GLOBALS['phpgw_info']['server']['ldap_context'])
|
|
\layout Code
|
|
|
|
{
|
|
\layout Code
|
|
|
|
$GLOBALS['config_error'] = 'Contact context for ldap must be
|
|
different from the context used for accounts';
|
|
\layout Code
|
|
|
|
}
|
|
\layout Code
|
|
|
|
elseif($value == $GLOBALS['phpgw_info']['server']['ldap_group_context'])
|
|
\layout Code
|
|
|
|
{
|
|
\layout Code
|
|
|
|
$GLOBALS['config_error'] = 'Contact context for ldap must be
|
|
different from the context used for groups';
|
|
\layout Code
|
|
|
|
}
|
|
\layout Code
|
|
|
|
else
|
|
\layout Code
|
|
|
|
{
|
|
\layout Code
|
|
|
|
$GLOBALS['config_error'] = '';
|
|
\layout Code
|
|
|
|
}
|
|
\layout Code
|
|
|
|
}
|
|
\layout Standard
|
|
|
|
Here we created a function to check the entered value for the config item,
|
|
ldap_contact_context.
|
|
We want to make sure the admin did not set this value to one which would
|
|
conflict with another config item, used for accounts or groups in eGroupWare.
|
|
\layout Standard
|
|
|
|
config.php calls this function, sending it the POSTed value.
|
|
config.php continues, adding all other config items from the POSTed values.
|
|
\layout Standard
|
|
|
|
The variable $GLOBALS['config_error'] is parsed through lang(), then appended
|
|
to the local variable, $error.
|
|
If this has any value after the POSTed variables are checked, the form
|
|
then has its {error} tag filled with this result.
|
|
The form is displayed again, with the error.
|
|
If $error has no value, config.php redirects to admin/index.php.
|
|
\layout Standard
|
|
|
|
However, there is one more function that may be included in hook_config_validate.
|
|
inc.php:
|
|
\layout Code
|
|
|
|
/* Check all settings to validate input.
|
|
Name must be 'final_validation' */
|
|
\layout Code
|
|
|
|
function final_validation($value='')
|
|
\layout Code
|
|
|
|
{
|
|
\layout Code
|
|
|
|
if($value['contact_repository'] == 'ldap' && !$value['ldap_contact_dn'])
|
|
\layout Code
|
|
|
|
{
|
|
\layout Code
|
|
|
|
$GLOBALS['config_error'] = 'Contact dn must be set';
|
|
\layout Code
|
|
|
|
}
|
|
\layout Code
|
|
|
|
elseif($value['contact_repository'] == 'ldap' && !$value['ldap_contact_c
|
|
ontext'])
|
|
\layout Code
|
|
|
|
{
|
|
\layout Code
|
|
|
|
$GLOBALS['config_error'] = 'Contact context must be set';
|
|
\layout Code
|
|
|
|
}
|
|
\layout Code
|
|
|
|
else
|
|
\layout Code
|
|
|
|
{
|
|
\layout Code
|
|
|
|
$GLOBALS['config_error'] = '';
|
|
\layout Code
|
|
|
|
}
|
|
\layout Code
|
|
|
|
}
|
|
\layout Standard
|
|
|
|
config.php checks for the existence of the function 'final_validation()'.
|
|
This function can be used to check all form values at once.
|
|
It gets sent the entire $newsettings array POSTed from the form.
|
|
As with the other functions in this file, final_validation() should set
|
|
$GLOBALS['config_error'] if there is a problem.
|
