 <title id="configuration.options-variability.title">Options variability</title>


 
 <para>


 
 


 
 This section does not descibe new field option or options. It just extend the


 
 prossibility of their initialization. Options variability feature can be


 
 applied to each field option.


 
 


 
 </para>


 
 <para>


 
 


 
 There is often a situation, when you want to have some field option in effect


 
 only on particular page(s). But on other pages you do not want to have this


 
 option in effect. So there are pages where field option should be taken into


 
 consideration, but there are also page when not.


 
 


 
 </para>


 
 <para>


 
 


 
 The good example for this is <varname>['trimlen']</> option. Imagine you will


 
 set something like this:


 
 


 
 <example><title>Init without options variability</title>


 
 <programlisting><![CDATA[


 
 $opts['fdd']['col_name']['trimlen'] = 30;


 
 ]]></programlisting>


 
 </example>


 
 


 
 This will trim the maximum length of text to 30 characters on all possible


 
 pages, which in this case for this option are:


 
 


 
 <itemizedlist spacing=compact>


 
 <listitem><simpara>table list</></>


 
 <listitem><simpara>table filter</></>


 
 <listitem><simpara>record view</></>


 
 <listitem><simpara>record delete</></>


 
 </itemizedlist>


 
 


 
 </para>


 
 <para>


 
 


 
 This is nice and it will work as expected, however on record view page it may


 
 be desirable to see whole field content, no only first 30 characters. Similary


 
 we could want this also for delete page.


 
 


 
 </para>


 
 <para>


 
 


 
 Thus there is a possiblity to restrict particular option effect only for


 
 selected types of pages. In our case we want to resctrict


 
 <varname>['trimlen']</> option affect to table listing and table filtering


 
 pages. This can be done in the following way. Take a look at "|LF" string in


 
 the definition.


 
 


 
 <example><title>Init with options variability</title>


 
 <programlisting><![CDATA[


 
 $opts['fdd']['col_name']['trimlen|LF'] = 30;


 
 ]]></programlisting>


 
 </example>


 
 


 
 </para>


 
 <para>


 
 


 
 Every restriction letter stands for particular page type. They are the same as


 
 they are described in list under <xref linkend="configuration.options"


 
 endterm="configuration.options"> subsection.


 
 


 
 </para>
