<h1>eTemplate-reference - Templates and Dialog-Editor for eGroupWare</h1>
<h3>by Ralf Becker <a href="#" onClick="document.location='mai'+'lto:RalfBecker'+unescape('%40')+'outdoor-training'+unescape('%2E')+'de'; return false;">RalfBecker AT outdoor-training DOT de</a></h3>
<p>A reference documentation about the new eTemplates and the <a href="#reference">syntax and parameters</a>
of the several widgets.</p>
<hr>
<h1>Introduction - The concept of the eTemplates</h1>
<p>As I already covered this in the <a href="etemplate.html">Tutorial</a>, I like would suggest to have a look
there if your are not familiar with the overal concept.</p>
<p>There are two possibilities now to create an eTemplate:</p>
<ol>
<li>Use the eTemplate-Editor (as descript in the <a href="etemplate.html">Tutorial</a>) to interactivly
design your template.
<li>Write a xml-file in a Syntax similar to XUL (the mozilla UI-interface definition language) and import
it into the database with the eTemplate-Editor
</ol>
<hr>
<h1>The xml-interface to the eTemplates</h1>
<p>The eTemplates-Editor can import and export now eTemplates as xml-files. Here is short example showing
an eTemplate from the example app in the <a href="etemplate.html">Tutorial</a>
(here are screenshots of the template in the <a href="editor.gif">editor</a> and the
<a href="show.gif">show-function</a>):</p>
<pre>
&lt;?xml version="1.0"?>
<span>&lt;!-- $Id$ --></span>
&lt;overlay>
&lt;template id="et_media.edit" template="" lang="" group="" version="">
&lt;grid width="100%">
&lt;columns>
&lt;column/>
&lt;column/>
&lt;column/>
&lt;column/>
&lt;/columns>
&lt;rows>
&lt;row>
&lt;description options="ib" span="all" value="eTemplates MediaDB" no_lang="1" id="msg"/>
&lt;/row>
&lt;row>

&lt;/row>

&lt;/row>
&lt;row>
&lt;description span="all"/>
&lt;/row>
&lt;row>
&lt;button label="Read" id="read" statustext="reads or searches for entries matching the criteria above"/>
&lt;button label="Save" id="save" statustext="saves the change to the db"/>
&lt;button label="Cancel" id="cancel" statustext="clears the form, without changing anything"/>
&lt;button label="Delete" id="delete" statustext="deletes an entry"/>
&lt;/row>
&lt;/rows>
&lt;/grid>
&lt;/template>
&lt;/overlay>
</pre>
<p>The tags / widget-names and attributes / parameters used are as close as possible to XUL. For more
information about XUL refer to <a href="http://www.xulplanet.com">www.xulplanet.com</a> or the Mozilla docs
<a href="http://www.mozilla.org/xpfe/xulref/">www.mozilla.org/xpfe/xulref/</a>.</p>
<p>Please keep in mind that the xml-files used to store the eTemplates are only similar to XUL and
implement only a subset of XUL. Here are the main differences:</p>
<ul>
<li>only certain widgets and widget attributes are implemented
<li>xul-files can contain the actual content or refer to it via a datasources (RDF's) and use a
different template syntax to fill in content from a variable: &lt;label value="?label"/><br />
eTemplates get there content from an array passed to the exec or show-function of the template-object
and reference to the content by the id / name-field of each widget.
<li>xul-files can contain an unlimited number of nested elements, the xml-root-node of an eTemplates has to
be an overlay, containing multiple (non-xul) &lt;template>'s. That templates can contain now (HEAD)
a tree of other widgets, but not other templates direct. You can use &lt;template id="app.template_name" />
to load an other template by its name.</i>
</ul>
<p>Like XUL the eTemplate-xml-files are quite strict with the xml-syntax:</p>
<ul>
<li>All tags and attributes must be written in lowercase
<li>All strings must be double quoted, like id="string"
<li>Every XUL widget must use close tags (either &lt;tag>&lt;/tag> or &lt;tag/>) to be well-formed
<li>All attributes must have a value, no &lt;tag attr> it has to be &lt;tag attr="1">
</ul>

</tr>
<tr>
<td><b>Type</b></td>
<td>type<br /><i>(only for<br />sub-types)</td>
<td>no</td>
<td>type</td>
<td>
The type of the widget is stored in the tag itself, some widgets have sub-types (unknow to XUL).
In that case the subtype is stored in the type attribut.<br />
The Type / tag has to be either the name of a standard eTemplate-widget or of
an already existing <a href="#extensions">extension</a>.
</td>
</tr>
<tr>
<td><b>Name</b></td>
<td>id</td>
<td>yes</td>
<td>name</td>
<td>
A string to locate the content for the widget in the content array (index) to show the dialog
and for the returned content.
Can be left blank or be obmitted as xml-attribut if the widget needs no content.<p>
The name can contain the following variables, which gets expanded before they are used as
array index (for an example see the <a href="etemplate.html">Tutorial</a>):<br />
<table>
<tr>
<td><b>$c</b></td>
<td>the column-number (starting with 0, if you have a header, data-cells start at 1)</td>
</tr><tr>
<td><b>$col</b></td>
<td>the column-letter: 'A', 'B', 'C', ...</td>
</tr><tr>
<td><b>$row</b></td>
<td>the row-number (starting with 0, if you have a header, data-cells start at 1)</td>
</tr><tr>
<td><b>$cont</b></td>
<td>the content-array the (sub-)template, on auto-repeated row's this could eg. be
used to generate button-names with id-values in it: "del[$cont[id]]" expands to "del[123]",
if $cont = array('id' => 123)</td>
</tr><tr>
<td><b>$row_cont</b></td>
<td>the sub-array indexed by $row of the content-array, on auto-repeated row's this could eg. be
used to generate button-names with id-values in it: "del[$row_cont[id]]" expands to "del[123]",
if $cont = array('1' => array('id' => 123),'2' => array('id' => 456)) and $row = 1</td>
</tr><tr>
<td><b>$c_<br />$col_<br />$row_</b></td>
<td>are the respective values of the previous template-inclusion,
eg. the column-headers in the eTemplate-editor are templates itself,
to show the column-name in the header you can not use $col as it will
be constant as it is always the same col in the header-template,
what you want is the value of the previous template-inclusion.</td>
</tr>
</table>
</td>
</tr>
<tr>
<td><b>Label</b></td>
<td>label</td>
<td>no</td>
<td>label</td>
<td>
The label is displayed by default in front (for radiobuttons behind) each widget (if not empty).
If you want to specify a different position, use a '%s' in the label, which gets replaced by
the widget itself. Eg. '%s Name' to have the label Name behind a checkbox.
The label can contain variables, as descript for name.
If the label starts with a '@' it is replaced by the value of the content-array at this
index (with the '@'-removed and after expanding the variables).<br />
<b>Note</b>: The label gets always translated, if its longer than 1 char! If this is not
disired, use a label widget, place the not-to-translate label in the content-array
<u>and</u> check NoTranslation or set the xml attribute no_lang.
</td>
</tr>
<tr>
<td><b>Help</b></td>
<td>statustext</td>
<td>yes</td>
<td>help</td>
<td>
This text / help-message is displayed in the status-bar of the browser when the widget gets focus
(or as tooltip for buttons or general in gtk).
If the user has JavaScript switched off, the help-texts get NOT submitted, as this is detected.
If the helptext starts with a '@' it is replaced by the value of the content-array at this
index (with the '@'-removed and after expanding the variables).
</td>
</tr>
<tr>
<td><b>Options</b></td>
<td>?</td>
<td>?</td>
<td>size</td>
<td>
This attribute controls certain aspects of the different widgets. It's meaning and xml / xul-values
are document with the widgets.
If the options-string starts with a '@' it is replaced by the value of the content-array at this
index (with the '@'-removed and after expanding the variables).
</td>
</tr>
<tr>
<td><b>NoTranslation</b></td>
<td>no_lang</td>
<td>no</td>

If checked the content of the widget and the label gets NOT translated.<br />
The helptext of a widget is always translated.

the widget / field empty.<br />
</td>

<tr>
<td><b>Readonly</b></td>
<td>readonly</td>
<td>yes</td>
<td>readonly</td>
<td>
If checked (xml-attr: readonly="true") the widget will NOT be editable.
If it is not supported by the browser, the etemplate-class makes shure that no
changes / content is transmitted back to the app.
Only applicable to widgets with input capabilities. Readonly Buttons get removed
from the dialog, like they where disabled.
The readonly attribute could be set on runtime via a readonly-array sublied to
the exec or show function of the class, the value on index=name/id has to be true
to make a widget readonly.
</td>
</tr>
<tr>
<td><b>Disabled</b></td>
<td>disabled</td>
<td>yes</td>
<td>disabled</td>
<td>
If checked (xml-attr: disabled="true") the widget will NOT be shown.
For buttons this could be archived on runtime via setting them readonly.
</td>
</tr>
<tr>
<td><b>onChange</b></td>
<td>onchange</td>
<td>?</td>
<td>onchange</td>
<td>
If checked (xml-attr: onchange="1") and the contet of the widget is changed by
the user, the form will be submitted.
Via xml or by a program other values can be set (not in the editor at the moment and
this is not compatible with the phpGTK implementation of the eTemplates).
</td>
</tr>
<tr>
<td><b>Span, Class</b></td>
<td>span<br />class</td>
<td>span: no<br />class: yes</td>
<td>span</td>
<td>
In the editor and internaly this field contains two comma-separated values:<p>
<b>span</b>: how many cell a widget should span (default is one), the special value
of 'all' can be used to indicate it should span all remaining cells of a row.
This is not supported by xul-grid's at the moment, but is planned to be.<p>
<b>class</b>: the CSS class for the widget.
If the class-string starts with a '@' it is replaced by the value of the content-array at this
index (with the '@'-removed and after expanding the variables).

Disables (=dont show it) a row/column if a certain criteria is (not (=!)) meet.<br />
If no '=...' / 2. value is given, the test is made on the first value being not empty, else
the test is made by comparing the two values. Instead of a value you can give a name as an
index into the content prefixed by @. Examples:<br />
<b>!@data</b> disables row/col if value of data is empty, <br />
<b>@val=false</b> disables if value of val is equal to (the string) 'false'

<b>class</b>: the CSS class for the row, there are 4 predefined css-classes:
nmh: next-match-header-background, nmr: alternating next-match-row-background which
gets replaced by the etemplate class with nmr0 or nmr1.<p>
<b>valign</b>: vertical alignment of the widgets in the row: 'top', 'middle' (default)
or 'bottom'

This text get displayed if an input-field is empty <u>and</u> does not have the
input-focus (blur). It can be used to show a default value or a kind of help-text.<br />
If it contains a text (eg. 'Search...'), this text is run through lang(), if it contains
a reference to the content array (eg. '@blur_text') it does <u>not</u> get translated.

<b>Options</b>: [datetime-storage-format] [,&1=year-no-selectbox|&2=today-button|&4=one-min-steps|&8=ro-suppress-0h0]<br />
<b>datetime-storage-format</b> is the format, in which the date is stored in the variable:
empty means an unix-timestamp (in GMT), or a string containing the letters <b>Y</b>, <b>m</b>,
<b>d</b>, <b>H</b>, <b>i</b> plus separators, eg. 'Y-m-d': 2002-12-31. The storage format

to do with the format of the display, which is only determined by the users preferences.)<br />
<b>year-no-selectbox</b> if set (&1) an int-widget (input-field) is used instead of a
select-year widget.<br />
<b>today-button</b>: if set (&2) a [Today] button is displayed which sets the fields to
the up-to-date date (via javascript)<br />
<b>one-min-steps</b>: if set (&4) the minute-selectbox uses one minutes steps, default 5min steps<br />
<b>ro-suppress-0h0</b>: if set (&8) the time is suppressed for readonly and a time of 0h0<br />
<b>day-of-week-prefix</b>: if set (&16) readonly dates get prefixed with the day of week<br />
<b>week-number-prefix</b>: if set (&32) readonly dates get prefixed with lang('Wk') & weeknumber<br />
<b>Sub-widgets</b>: <b>date-time</b>: a date and a time and <b>date-timeonly</b> or <b>date-houronly</b>: only a time / hour<br />
These widgets allow the input of times too or only, they use 12h am/pm or 24h format as
specified in the user prefs.<br />

set a key that matches.
For example, if your column name is private_phone, use the eTemplate editor to set column disabled to @no_private_phone,

These widget are an optional part of the nextmatch widget.<p>
<b>nextmatch-sortheader</b><br />
Widget to be placed as a colum-header in the headerline of a nextmatch-template. It allows, by clicking on it,
to order the lines of the nextmatch after a certain column. The column-name is given as <b>name</b> (xml:id) the
<b>label</b> is show as a link of button (no javascript). One can specify a default sorting: <b>options</b>={DESC|ASC} (default=ASC),
to be used when the header is clicked for the first time. Consecutive click on the header change the sorting
direction, indicated by a little up- or down-arrow. As a second comma-separated parameter one can specify an extra
label for the column-selection.<p>
<b>nextmatch-filterheader</b><br />
Widget to allow to show only certain row, which match a selected filter-value. The column-name is given as <b>name</b>
(xml:id), the options of the displayed selectbox need to be set as for an ordinary selectbox (eg. in the options
parameter to the uietemplate::exec function). If no extra-label is given in options, lang('all') will be used for
the empty value, which means no filter activ. An (optional) <b>label</b> can be given and is also used for the column-selection.<p>
<b>nextmatch-customfilter</b><br />
The custom filterheader allows to use other (select-)widgets to filter by them. They have to be specified as the first
parameter in the comma-separated options attribute. In all other aspects it is identical to the filterheader.<p>
<b>nextmatch-accountfilter</b><br />
The Accountfilter allows to select users (via the prefered user-selection-method) to filter by them.
It's identical to a <b>nextmatch-customfilter</b> with options="select-account".<p>
<b>nextmatch-header</b><br />
Just a header-label for a nextmatch column. It names the column for the column for the column-selection (in difference to the label).
The name is used to hide the column (with a 'no_' prefix) and as the name for the preference.
A different label for the column-selection preference can be specified via the option field.<p>
<i><u>Note</u>:</i> All four widgets interoperate with the nextmatch-widget which passes the set values as part if
the query-parameter to its get_rows function, they are <u>not</u> returned in the rows sub-array.

These widgets are the UI-part of the link-class ({bo|so}link) in the API.<p>
eGroupWare has a linking system that lets you link two records from different apps together.<p>
For example, you can link the addressbook entry of the person you're meeting with to the meeting on your calendar,
or an infolog entry for the phone call you made to postpone the meeting.<p>
To display links in your own application, you should use the LinkList group of widgets.<p>
<b>link-list</b><br />
Widget to shows the links to an entry and a Unlink Button for each link. <p>
It needs an array with two entries. If you name the LinkList widget 'links', you need: </p>
<pre>
$data['links']['to_app'] = 'myapp';
$data['links']['to_id'] = $record_id;
</pre>
<p>This will display links where the $record_id record of myapp is one side of the link.
Make sure that both variables are properly defined before the form template gets executed.
<p><b>link-to</b><br />
Widget to make a links to other entries of link-aware apps and to attach files.<p>
<i><u>Note</u>:</i> Both Widgets can be used on the same template with the <u>same</u> name. They share
the content of the variable with that name, which contains just the id of the entry in the current app.<p>
<b>link-string</b><br />
Comma-separated list of link-titles with a link to its view-method, value is like the return
of bolink::get_links().<p>
<hr>
Before you can use a link to your application, you need to specify some information in a 'search_link' hook.<p>
In your setup.inc.php, you need to point $setup_info['myapp']['hooks']['search_link'] to a function that will return an array: <p>
<pre>return array(
'query' =&gt;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 'myapp.bo_myapp.link_query',&nbsp;
// A function that takes a search string
// and returns a list of matching records
'title' =&gt;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 'myapp.bo_myapp.link_title',&nbsp;
// A function that takes an id from one side
// of a link and returns a string for that entry
'view'&nbsp; =&gt;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; array('menuaction'=&gt;'myapp.ui_myapp.link_view'),
// Function to view a link, may be an existing view function
'view_id'&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; =&gt;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 'link_id',&nbsp;
// name of the id variable provided to the view function above
'add'&nbsp;&nbsp; =&gt;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; array('menuaction' =&gt; 'myapp.ui_myapp.new_entry'),&nbsp;
// Function to add a new entry
);
</pre>
<p>Also, make sure that the declared methods are implemented and methods from the UI class are listed in its $public_methods attribute:
<pre>
class ui_myapp {
var $public_methods = array(
'view' => true,
'add' => true
);
...
}

<p>The Ajax Select is a Combo Box. It lets the user type anything they want, and choose from a list of options that are presented below. The user is not limited to the choices, but there is
some checking done. If what they type returns several results, and they don't choose one, for example. You can reject
any values you don't like in your UI code. It is best used where you might normally want to use a selectbox but your list of data is too large. You can have several on one page, but the name
must be different for each.</p>
<p><b>Options</b> can be found under the "AJAX Select options" section of the pop-up. </p>
<p><b>Data Source</b>: the list options, can be any function that can provide data for a nextmatch widget.</p>
<p><b>Title Source</b>: When an option from the list is selected, the text in the search function is replaced with the result of this function. The ID Field is passed. link_title() functions work well.</p>
<p><b>ID Field</b>: Data Source is expected to return an array as for a nextmatch, with several columns. This is the key of the column you actually want returned for a value.</p>
<p><b>Result row template</b>: (Optional) You can provide a custom eTemplate to use for the list options. It should be constructed similarly to a row template for a nextmatch, and will be repeated for each option.</p>
<p><b>Link</b>: (Optional) If the field is read-only, and Link is provided, the widget will turn into a link. Link should look like: perp_ap.ui_perp_supplier.edit&supplier_id=${cont[supplier_id]} where ID Field is supplier_id.</p>
<p><b>Icon</b>: (Optional) An icon placed to the left of the search box, to help indicate what the user is searching (addresses, suppliers, etc.). It will be automatically resized.</p>

<h3>One remark about cross-site-scripting</h3>
The following eTemplate Widgets are parsing its content before displaying through <b>htmlspecialchars()</b> to
correctly display the content and to gard against malecious data (like scripts etc.):
<ul>
<li>Label
<li>Text, Textarea
<li>Integer, Float
<li>SelectBoxes (it's options-strings)
<li>LinkWidgets: link-to, link-list, link-string
</ul>
This is done in most cases by the underlaying html-class and not direct in eTemplate.

<h1>How to implement new widgets / extensions to the eTemplates?</h1>
<p>The eTemplates have an interface to extend them with new widgets. These widgets are php-classes, can use
eTemplates to define the UI of the new widget and are stored in the eTemplate's inc-dir or the inc-dir of a
eGroupWare application. The editor and the etemplate-class autoload the existing extensions.</p>
<i>I will made more documentation about the interface availible soon. For now have a look for the source
of the existing extensions.</i>
