PHP Zikula_View::getTplVar方法代码示例

/**
 * Pop a field of an array and assign its value to a template variable.
 *
 * Available attributes:
 *  - array  (string) Name of the template array variable to process
 *  - field  (string) Name of the array field to assign then unset
 *  - unset  (bool)   Flag to specify if the field must be unset or not (default: true)
 *  - assign (string) Name of the assign variable to setup (optional)
 *
 * Example:
 *
 *  Having an $objarray in our template, we want to process its fields in different
 *  sections of the template, so we get the needed fields separately on the desired positions,
 *  clearing the array in the process.
 *
 *  For instance, the $hooks array resulted of notify the 'display_view' hooks, can be
 *  processed individually using this plugin:
 *
 *  <samp>{array_pop array='hooks' field='EZComments'}</samp>
 *  <samp>{array_pop array='hooks' field='EZComments' assign='comments'}</samp>
 *
 *  And display later the remaining ones with a foreach.
 *
 * @param array       $params All attributes passed to this function from the template.
 * @param Zikula_View $view   Reference to the {@link Zikula_View} object.
 *
 * @return mixed False on failure, void if the value is assigned, or the value extracted itself.

/**
 * Assign an array field to a variable or display it in the output.
 *
 * Available attributes:
 *  - array  (mixed)  Name of the template array variable or the array itself to process
 *  - field  (string) Name of the array field to assign
 *  - assign (string) Name of the assign variable to setup (optional)
 *
 * Example:
 *
 *  Having an $objarray in our template, we want to check if a field is set
 *  or extract one field on another var to process it apart.
 *
 *  For instance, we need the localized output of a category. We have the
 *  $category variable, and we pass the display_name to the plugin, to get the local name:
 *
 *  <samp>{array_field array=$category.display_name field=$lang assign='displayname'}</samp>
 *
 *  And if you need to be sure that the value is set, you must test it:
 *
 *  <samp>{if $displayname}</samp>
 *
 *  In the other hand, if you have a field that exists for sure, that is in the first level
 *  of the array and you want to extract it to another variable, you can do:
 *
 *  <samp>{array_field array='category' field='id' assign='cid'}</samp>
 *
 * @param array       $params All attributes passed to this function from the template.
 * @param Zikula_View $view   Reference to the {@link Zikula_View} object.
